Steps for Determining Correct Load Limit 1. Locate the statement “The combined weight of occu- pants and cargo should never exceed XXX lbs or XXX kg” on your vehicle’s placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. STARTING AND OPERATING 359 NOTE: • The following table shows examples on how to calcu- late total load, cargo/luggage, and towing capacities of your vehicle with varying seating configurations and number and size of occupants. This table is for illustration purposes only and may not be accurate for the seating and load carry capacity of your vehicle. • For the following example, the combined weight of occupants and cargo should never exceed 865 lbs (392 kg). 3. Subtract the combined weight of the driver and pas- sengers from XXX lbs or XXX kg. 4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if “XXX” amount equals 1,400 lbs (635 kg) and there will be five 150 lb (68 kg) passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (295 kg) (since 5 x 150 = 750, and 1400 – 750 = 650 lbs [295 kg]). 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4. 6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle. 360 STARTING AND OPERATING WARNING! Safety STARTING AND OPERATING 361 Overloading of your tires is dangerous. Overloading can cause tire failure, affect vehicle handling, and increase your stopping distance. Use tires of the recommended load capacity for your vehicle. Never overload them. TIRES — GENERAL INFORMATION Tire Pressure Proper tire inflation pressure is essential to the safe and satisfactory operation of your vehicle. Three primary areas are affected by improper tire pressure: WARNING! cause accidents. sult in over-heating and tire failure. • Improperly inflated tires are dangerous and can • Under-inflation increases tire flexing and can re- • Over-inflation reduces a tire’s ability to cushion shock. Objects on the road and chuckholes can cause damage that result in tire failure. • Unequal tire pressures can cause steering prob- • Over-inflated or under-inflated tires can affect vehicle handling and can fail suddenly, resulting in loss of vehicle control. lems. You could lose control of your vehicle. (Continued) 362 STARTING AND OPERATING WARNING! (Continued) • Unequal tire pressures from one side of the ve- hicle to the other can cause the vehicle to drift to the right or left. • Always drive with each tire inflated to the recom- mended cold tire inflation pressure. Economy Improper inflation pressures can cause uneven wear patterns to develop across the tire tread. These abnormal wear patterns will reduce tread life resulting in a need for earlier tire replacement. Under-inflation also increases tire rolling resistance and results in higher fuel consumption. Ride Comfort and Vehicle Stability Proper tire inflation contributes to a comfortable ride. Over-inflation produces a jarring and uncomfortable ride. Both under-inflation and over-inflation affect the stability of the vehicle and can produce a feeling of sluggish response or over responsiveness in the steering. Unequal tire pressures can cause erratic and unpredict- able steering response. Unequal tire pressure from side to side may cause the vehicle to drift left or right. Tire Inflation Pressures The proper cold tire inflation pressure is listed on the driver’s side “B” Pillar. The pressure should be checked and adjusted, as well as inspected for signs of tire wear or visible damage, at least once a month. Use a good quality pocket-type gauge to check tire pressure. Do not make a visual judgement when determining proper inflation. Radial tires may look properly inflated even when they are under-inflated. CAUTION! After inspecting or adjusting the tire pressure, al- ways reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage it. Inflation pressures specified on the placard are always cold tire inflation pressure. Cold tire inflation pressure is defined as the tire pressure after the vehicle has not been driven for at least three hours, or driven less than 1 mile (1.6 km) after a three-hour period. The cold tire inflation pressure must not exceed the maximum inflation pres- sure molded into the tire sidewall. Check tire pressures more often if subject to a wide range of outdoor temperatures, as tire pressures vary with temperature changes. STARTING AND OPERATING 363 Tire pressures change by approximately 1 psi (7 kPa) per 12°F (7°C) of air temperature change. Keep this in mind when checking tire pressure inside a garage, especially in the winter. Example: If garage temperature = 68°F (20°C) and the outside temperature = 32°F (0°C) then the cold tire inflation pressure should be increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12°F (7°C) for this outside temperature condition. Tire pressure may increase from 2 to 6 psi (13 to 40 kPa) during operation. DO NOT reduce this normal pressure build-up, or your tire pressure will be too low. 364 STARTING AND OPERATING Tire Pressures For High Speed Operation The manufacturer advocates driving at safe speeds within posted speed limits. Where speed limits or condi- tions are such that the vehicle can be driven at high speeds, maintaining correct tire inflation pressure is very important. Increased tire pressure and reduced vehicle loading may be required for high-speed vehicle opera- tion. Refer to original equipment or an authorized tire dealer for recommended safe operating speeds, loading and cold tire inflation pressures. WARNING! High speed driving with your vehicle at or above maximum load is dangerous. The added strain on your tires could cause them to fail. You could have a serious accident. Do not drive a vehicle loaded to the maximum capacity at continuous speeds above 75 mph (120 km/h). Radial-Ply Tires WARNING! Combining radial ply tires with other types of tires on your vehicle will cause your vehicle to handle poorly. The instability could cause an accident. Al- ways use radial tires in sets of four. Never combine them with other types of tires. Cuts and punctures in radial tires are repairable only in the tread area because of sidewall flexing. Consult your authorized dealer for radial tire repairs. Compact Spare Tire – If Equipped The compact spare is for temporary emergency use with radial tires. It is engineered to be used on your style vehicle only. Since this tire has limited tread life, the original tire should be repaired (or replaced) and rein- stalled at the first opportunity. WARNING! CAUTION! STARTING AND OPERATING 365 Temporary use spare tires are for emergency use only. With these tires, do not drive more than 50 mph (80 km/h). Temporary use spare tires have limited tread life. When the tread is worn to the tread wear indicators, the temporary use spare tire needs to be replaced. Be sure to follow the warnings, which apply to your spare. Failure to do so could result in spare tire failure and loss of vehicle control. Do not install a wheel cover or attempt to mount a conventional tire on the compact spare wheel, since the wheel is designed specifically for the compact spare. Do not install more than one compact spare tire/wheel on the vehicle at any given time. Because of the reduced ground clearance, do not take your vehicle through an automatic car wash with the compact spare installed. Damage to the vehicle may result. Tire Spinning When stuck in mud, sand, snow, or ice conditions, do not spin your vehicle’s wheels above 30 mph (48 km/h). WARNING! Fast spinning tires can be dangerous. Forces generated by excessive wheel speeds may cause tire damage or failure. A tire could explode and injure someone. Do not spin your vehicle’s wheels faster than 30 mph (48 km/h) when you are stuck, and do not let anyone near a spinning wheel no matter what the speed. 366 STARTING AND OPERATING Tread Wear Indicators Tread wear indicators are in the original equipment tires to help you in determining when your tires should be replaced. These indicators are molded into the bottom of the tread grooves. They will appear as bands when the tread depth becomes 1/16 in (2 mm). When the tread is worn to the tread wear indicators, the tire should be replaced. CAUTION! Proper operation of four-wheel drive vehicles de- pends on tires of equal size, type and circumference on each wheel. Any difference in tire size can cause damage to the transfer case. Tire rotation schedule should be followed to balance tire wear. 1 — Worn Tire 2 — New Tire Life Of Tire The service life of a tire is dependent upon various factors including but not limited to: • Driving style • Tire pressure • Distance driven WARNING! Tires and the spare tire should be replaced after six years, regardless of the remaining tread. Failure to follow this warning can result in sudden tire failure. You could lose control and have an accident resulting in serious injury or death. Keep dismounted tires in a cool, dry place with as little exposure to light as possible. Protect tires from contact with oil, grease, and gasoline. STARTING AND OPERATING 367 Replacement Tires The tires on your new vehicle provide a balance of many characteristics. They should be inspected regularly for wear and correct cold tire inflation pressure. The manu- facturer strongly recommends that you use tires equiva- lent to the originals in size, quality and performance when replacement is needed. (Refer to the paragraph on “Tread Wear Indicators”). Refer to the “Tire and Loading Information” placard for the size designation of your tires. The service description and load identification will be found on the original equipment tire. Failure to use equivalent replacement tires may adversely affect the safety, handling, and ride of your vehicle. We recommend that you contact your original equipment or an autho- rized tire dealer with any questions you may have on tire specifications or capability. 368 STARTING AND OPERATING WARNING! • Do not use a tire, wheel size or rating other than that specified for your vehicle. Some combinations of unapproved tires and wheels may change sus- pension dimensions and performance characteris- tics, resulting in changes to steering, handling, and braking of your vehicle. This can cause unpredict- able handling and stress to steering and suspen- sion components. You could lose control and have an accident resulting in serious injury or death. Use only the tire and wheel sizes with load ratings approved for your vehicle. • Never use a tire with a smaller load index or capacity than what was originally equipped on your vehicle. Using a tire with a smaller load index could result in tire overloading and failure. You could lose control and have an accident. (Continued) WARNING! (Continued) • Failure to equip your vehicle with tires having adequate speed capability can result in sudden tire failure and loss of vehicle control. CAUTION! Replacing original tires with tires of a different size may result in false speedometer and odometer read- ings. TIRE CHAINS Use only compact chains, or other traction aids that meet SAE type “Class S” specifications. Chains must be the proper size for the vehicle, as recommended by the chain manufacturer. In addition, only install tire chains on P225/75R16 or smaller tires. CAUTION! To avoid damage to your vehicle, tires, or chains, observe the following precautions: • Do not use tire chains on vehicles equipped with tires other than P225/75R16 or smaller tires. There may not be adequate clearance for the chains and you are risking structural or body damage to your vehicle. • Because of limited chain clearance between tires and other suspension components, it is important that only chains in good condition are used. Bro- ken chains can cause serious vehicle damage. Stop the vehicle immediately if noise occurs that could suggest chain breakage. Remove the damaged parts of the chain before further use. (Continued) STARTING AND OPERATING 369 CAUTION! (Continued) • Install chains on the rear wheels as tightly as possible and then retighten after driving about 1⁄2 mile (0.8 km). bumps, especially with a loaded vehicle. • Do not exceed 45 mph (72 km/h). • Drive cautiously and avoid severe turns and large • Use on Rear Wheels only. • Do not drive for a prolonged period on dry pave- • Observe the tire chain manufacturer’s instructions on method of installation, operating speed, and conditions for use. Always use the lower sug- gested operating speed of the chain manufacturer if different from the speed recommended by the manufacturer. ment. 370 STARTING AND OPERATING These cautions apply to all chain traction devices, includ- ing link and cable (radial) chains. TIRE ROTATION RECOMMENDATIONS Tires on the front and rear axles of vehicles operate at different loads and perform different steering, handling, and braking functions. For these reasons, they wear at unequal rates, and develop irregular wear patterns. The suggested rotation method is the “forward-cross” shown in the following diagram. Tire Rotation These effects can be reduced by timely rotation of tires. The benefits of rotation are especially worthwhile with aggressive tread designs such as those on On/Off Road type tires. Rotation will increase tread life, help to main- tain mud, snow, and wet traction levels, and contribute to a smooth, quiet ride. CAUTION! Proper operation of four-wheel drive vehicles de- pends on tires of equal size, type and circumference on each wheel. Any difference in tire size can cause damage to the transfer case. Tire rotation schedule should be followed to balance tire wear. Refer to “Maintenance Schedule” for the proper mainte- nance intervals. Remember, more frequent rotation is permissible if desired. Also, correct for anything causing rapid or unusual wear prior to performing the tire rotation. TIRE PRESSURE MONITOR SYSTEM (TPMS) The Tire Pressure Monitor System (TPMS) will warn the driver of a low tire pressure based on the vehicle recom- mended cold placard pressure. STARTING AND OPERATING 371 The tire pressure will vary with temperature by about 1 psi (6.9 kPa) for every 12°F (6.5°C). This means that when the outside temperature decreases, the tire pressure will decrease. Tire pressure should always be set based on cold inflation tire pressure. This is defined as the tire pressure after the vehicle has not been driven for at least three hours, or driven less than 1 mile (1.6 km) after a three hour period. The cold tire inflation pressure must not exceed the maximum inflation pressure molded into the tire sidewall. Refer to “Tires – General Information” in “Starting and Operating” for information on how to properly inflate the vehicle’s tires. The tire pressure will also increase as the vehicle is driven. This is normal and there should be no adjustment for this increased pres- sure. The TPMS will warn the driver of a low tire pressure if the tire pressure falls below the low-pressure warning limit for any reason, including low temperature effects and natural pressure loss through the tire. 372 STARTING AND OPERATING The TPMS will continue to warn the driver of low tire pressure as long as the condition exists, and will not turn off until the tire pressure is at or above the recommended cold placard pressure. Once the low tire pressure warn- ing (Tire Pressure Monitoring Telltale Light) illuminates, you must increase the tire pressure to the recommended cold placard pressure in order for the “Tire Pressure Monitoring Telltale Light” to turn off. The system will automatically update and the “Tire Pressure Monitoring Telltale Light” will turn off once the system receives the updated tire pressures. The vehicle may need to be driven for up to 20 minutes above 15 mph (25 km/h) in order for the TPMS to receive this information. For example, your vehicle may have a recommended cold (parked for more than three hours) placard pressure of 33 psi (227 kPa). If the ambient temperature is 68°F (20°C) and the measured tire pressure is 28 psi (193 kPa), a temperature drop to 20°F (-7°C) will decrease the tire pressure to approximately 24 psi (165 kPa). This tire pressure is low enough to turn ON the “Tire Pressure Monitoring Telltale Light.” Driving the vehicle may cause the tire pressure to rise to approximately 28 psi (193 kPa), but the “Tire Pressure Monitoring Telltale Light” will still be on. In this situation, the “Tire Pressure Monitoring Telltale Light” will turn off only after the tires are inflated to the vehicle’s recommended cold placard pressure value. CAUTION! • The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures and warning have been established for the tire size equipped on your vehicle. Undesirable system operation or sensor damage may result when us- ing replacement equipment that is not of the same size, type, and/or style. Aftermarket wheels can cause sensor damage. Do not use aftermarket tire sealants or balance beads if your vehicle is equipped with a TPMS, as damage to the sensors may result. • After inspecting or adjusting the tire pressure, always reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the Tire Pressure Moni- toring Sensor. STARTING AND OPERATING 373 while adjusting your tire pressure. NOTE: • The TPMS is not intended to replace normal tire care and maintenance, or to provide warning of a tire failure or condition. • The TPMS should not be used as a tire pressure gauge • Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. • The TPMS is not a substitute for proper tire mainte- nance, and it is the driver’s responsibility to maintain correct tire pressure using an accurate tire pressure gauge, even if under-inflation has not reached the level to trigger illumination of the “Tire Pressure Monitoring Telltale Light.” 374 STARTING AND OPERATING • Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire. Base System The Tire Pressure Monitor System (TPMS) uses wireless technology with wheel rim mounted electronic sensors to monitor tire pressure levels. Sensors, mounted to each wheel as part of the valve stem, transmit tire pressure readings to the receiver module. It is particularly important for you to check the NOTE: tire pressure in all of the tires on your vehicle monthly and to maintain the proper pressure. The TPMS consists of the following components: • Receiver Module • Four Tire Pressure Monitoring Sensors • Tire Pressure Monitoring Telltale Light The matching full-size spare wheel and tire assembly (if equipped) has a tire pressure monitoring sensor. The matching full-size spare can be used in place of any of the four road tires. The TPMS will only monitor the pressure in the full-size spare when it is used in place of a road tire. Otherwise, a spare with a pressure below the low- pressure limit will not cause the “Tire Pressure Monitor- ing Telltale Light” to illuminate or the chime to sound. Tire Pressure Monitoring Low Pressure Warnings The “Tire Pressure Monitoring Telltale Light” will illuminate in the instrument cluster and a chime will sound when tire pressure is low in one or more of the four active road tires. Should this occur, you should stop as soon as possible, check the inflation pressure of each tire on your vehicle, and inflate each tire to the vehicle’s recommended cold placard pressure value. Once the system receives the updated tire pres- sures, the system will automatically update and the “Tire Pressure Monitoring Telltale Light” will turn off. The vehicle may need to be driven for up to 20 minutes above 15 mph (25 km/h) in order for the TPMS to receive this information. Check TPMS Warning When a system fault is detected, the “Tire Pressure Monitoring Telltale Light” will flash on and off for 75 seconds and then remain on solid. The system fault will also sound a chime. If the ignition key is cycled, this sequence will repeat, providing the system fault still exists. The “Tire Pressure Monitoring Telltale Light” will turn off when the fault condition no longer exists. A system fault can occur due to any of the following: 1. Jamming due to electronic devices or driving next to facilities emitting the same radio frequencies as the TPMS sensors. 2. Installing some form of aftermarket window tinting that affects radio wave signals. STARTING AND OPERATING 375 3. Lots of snow or ice around the wheels or wheel housings. 4. Using tire chains on the vehicle. 5. Using wheels/tires not equipped with TPMS sensors. Vehicles with Full-Size Spare 1. The matching full-size spare wheel and tire assembly has a tire pressure monitoring sensor that can be moni- tored by the TPMS. 2. If you install the full-size spare in place of a road tire that has a pressure below the low-pressure warning limit, a chime will sound and the “TPMS Telltale Light” will turn on upon the next ignition key cycle. 3. Driving the vehicle for up to 20 minutes above 15 mph (25 km/h) will turn off the “TPMS Telltale Light,” as long as no tire pressure is below the low-pressure warning limit in any of the four active road tires. 376 STARTING AND OPERATING Vehicles with Compact Spare 1. The compact spare tire does not have a tire pressure monitoring sensor. Therefore, the TPMS will not monitor the pressure in the compact spare tire. 2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure warning limit, a chime will sound and the “TPMS Telltale Light” will turn on upon the next ignition key cycle. 3. After driving the vehicle for up to 20 minutes above 15 mph (25 km/h), the “TPMS Telltale Light” will flash on and off for 75 seconds and then remain on solid. 4. For each subsequent ignition key cycle, a chime will sound and the “TPMS Telltale Light” will flash on and off for 75 seconds and then remain on solid. 5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare, the TPMS will update automatically and the “TPMS Telltale Light” will turn off, as long as no tire pressure is below the low-pressure warning limit in any of the four active road tires. The vehicle may need to be driven for up to 20 minutes above 15 mph (25 km/h) in order for the TPMS to receive this information. Premium System – If Equipped The Tire Pressure Monitor System (TPMS) uses wireless technology with wheel rim mounted electronic sensors to monitor tire pressure levels. Sensors, mounted to each wheel as part of the valve stem, transmit tire pressure readings to the receiver module. It is particularly important for you to check the NOTE: tire pressure in all of the tires on your vehicle monthly and to maintain the proper pressure. The TPMS consists of the following components: • Receiver Module • Four Tire Pressure Monitoring Sensors STARTING AND OPERATING 377 will sound when tire pressure is low in one or more of the four active road tires. In addition, the Electronic Vehicle Information Center (EVIC) will display a graphic show- ing the pressure values of each tire with the low tire pressure values flashing. wheel-wells) • Three Trigger Modules (mounted in three of the four • Various Tire Pressure Monitoring System messages, which display in the Electronic Vehicle Information Center (EVIC) • Tire Pressure Monitoring Telltale Light The matching full size spare wheel and tire assembly (if equipped) has a tire pressure monitoring sensor. The full size spare can be used in place of any of the four road tires. A spare with a pressure below the low-pressure limit will not cause the “Tire Pressure Monitoring Telltale Light” to illuminate or the chime to sound. However, it will cause a “SPARE LOW PRESSURE” message to display in the EVIC. Tire Pressure Monitoring Low Pressure Warnings The “Tire Pressure Monitoring Telltale Light” will illuminate in the instrument cluster and a chime 378 STARTING AND OPERATING Should this occur, you should stop as soon as possible and inflate the tires with low pressure (those flashing in the EVIC graphic) to the vehicle’s recommended cold placard pressure value. Once the system receives the updated tire pressures, the system will automatically update, the graphic display in the EVIC will stop flash- ing, and the “Tire Pressure Monitoring Telltale Light” will turn off. The vehicle may need to be driven for up to 20 minutes above 15 mph (25 km/h) in order for the TPMS to receive this information. Check TPMS Warning When a system fault is detected, the “Tire Pressure Monitoring Telltale Light” will flash on and off for 75 seconds and then remain on solid. The system fault will also sound a chime. In addition, the EVIC will display a ⬙CHECK TPM SYSTEM⬙ message for three seconds and then display dashes (- -) in place of the pressure value to indicate which sensor is not being received. If the ignition key is cycled, this sequence will repeat, providing the system fault still exists. If the system fault no longer exists, the “Tire Pressure Monitoring Telltale Light” will no longer flash, and the ⬙CHECK TPM SYSTEM⬙ message will no longer display, and a pressure value will display in place of the dashes. A system fault can occur due to any of the following: 1. Jamming due to electronic devices or driving next to facilities emitting the same radio frequencies as the TPMS sensors. 2. Installing some form of aftermarket window tinting that affects radio wave signals. 3. Lots of snow or ice around the wheels or wheel housings. 4. Using tire chains on the vehicle. 5. Using wheels/tires not equipped with TPMS sensors. STARTING AND OPERATING 379 Vehicles with Full-Size Spare 1. The matching full size spare wheel and tire assembly has a tire pressure monitoring sensor that can be moni- tored by the TPMS. 2. If you install the full size spare in place of a road tire that has a pressure below the low-pressure warning limit, a chime will sound and the “TPMS Telltale Light” will turn on upon the next ignition key cycle. In addition, the EVIC will display a Low Pressure message and a graphic showing the low tire pressure value flashing. 3. After driving the vehicle for up to 20 minutes above 15 mph (25 km/h) the “TPMS Telltale Light” will turn OFF, as long as no tire pressure is below the low-pressure warning limit in any of the four active road tires. 4. The EVIC will display a graphic showing the tire pressure value in place of the flashing low tire pressure 380 STARTING AND OPERATING value. The EVIC will also display a “SPARE LOW PRESSURE” message to remind you to service the flat tire. Vehicles with Compact Spare 1. The compact spare tire does not have a tire pressure monitoring sensor. Therefore, the TPMS will not monitor the pressure in the compact spare tire. 2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure warning limit, upon the next ignition key cycle, the “TPMS Telltale Light” will remain on and a chime will sound. In addition, the graphic in the EVIC will still display a flashing pressure value. 3. After driving the vehicle for up to 20 minutes above 15 mph (25 km/h), the “TPMS Telltale Light” will flash on and off for 75 seconds and then remain on solid. In addition, the EVIC will display a ⬙CHECK TPM SYS- TEM⬙ message for three seconds and then display dashes (- -) in place of the pressure value. 4.

Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare, the TPMS will update automatically. In addition, the “TPMS Telltale Light” will turn off and the graphic in the EVIC will display a new pressure value instead of dashes (- -), as long as no tire pressure is below the low-pressure warning limit in any of the four active road tires. The vehicle may need to be driven for up to 20 minutes above 15 mph (25 km/h) in order for the TPMS to receive this information. General Information This device complies with Part 15 of the FCC rules and RSS 210 of Industry Canada. Operation is subject to the following conditions: • This device may not cause harmful interference. • This device must accept any interference received, including interference that may cause undesired operation. The tire pressure sensors are covered under one of the following licenses: United States . . . . . . . . . . . . . . . . . . . . . KR5S120123 Canada . . . . . . . . . . . . . . . . . . . . . . . . 2671-S120123 STARTING AND OPERATING 381 FUEL REQUIREMENTS All engines are designed to meet all emis- sions regulations and provide excellent fuel economy and performance when us- ing high quality unleaded “regular” gaso- line having an octane rating of 87. The use of premium gasoline is not recommended, as it will not provide any benefit over regular gasoline in these engines. Light spark knock at low engine speeds is not harmful to your engine. However, continued heavy spark knock at high speeds can cause damage and immediate service is required. Poor quality gasoline can cause problems such as hard starting, stalling, and hesitations. If you experi- ence these symptoms, try another brand of gasoline before considering service for the vehicle. 382 STARTING AND OPERATING Over 40 auto manufacturers worldwide have issued and endorsed consistent gasoline specifications (the World- wide Fuel Charter, WWFC) which define fuel properties necessary to deliver enhanced emissions, performance, and durability for your vehicle. The manufacturer recom- mends the use of gasoline that meets the WWFC speci- fications if they are available. Reformulated Gasoline Many areas of the country require the use of cleaner burning gasoline referred to as “Reformulated Gasoline.” Reformulated gasolines contain oxygenates, and are spe- cifically blended to reduce vehicle emissions and im- prove air quality. The manufacturer supports the use of reformulated gaso- lines. Properly blended reformulated gasolines will pro- vide excellent performance and durability of engine and fuel system components. Gasoline/Oxygenate Blends Some fuel suppliers blend unleaded gasoline with oxy- genates such as 10% ethanol, MTBE, and ETBE. Oxygen- ates are required in some areas of the country during the winter months to reduce carbon monoxide emissions. Fuels blended with these oxygenates may be used in your vehicle. CAUTION! DO NOT use gasolines containing Methanol or E85 Ethanol. Use of these blends may result in starting and drivability problems and may damage critical fuel system components. Problems that result from using methanol/gasoline or E85 Ethanol blends are not the responsibility of the manufacturer. While MTBE is an oxygenate made from Methanol, it does not have the negative effects of Methanol. E-85 Usage In Non-Flex Fuel Vehicles Non-FFV vehicles are compatible with gasoline contain- ing 10% ethanol (E10). Gasoline with higher ethanol content may void the vehicle’s warranty. If a Non-FFV vehicle is inadvertently fueled with E-85 fuel, the engine will have some or all of these symptoms: • operate in a lean mode • OBD II “Malfunction Indicator Light” on • poor engine performance • poor cold start and cold drivability • increased risk for fuel system component corrosion To fix a Non-FFV vehicle inadvertently fueled once with E-85 perform the following: • drain the fuel tank (see your authorized dealer) • change the engine oil and oil filter • disconnect and reconnect the battery to reset the STARTING AND OPERATING 383 engine controller memory More extensive repairs will be required for prolonged exposure to E-85 fuel. MMT In Gasoline MMT is a manganese containing metallic additive that is blended into some gasoline to increase octane. Gasoline blended with MMT provides no performance advantage beyond gasoline of the same octane number without MMT. Gasoline blended with MMT reduces spark plug life and reduces emission system performance in some vehicles. The manufacturer recommends that gasoline without MMT be used in your vehicle. The MMT content of gasoline may not be indicated on the gasoline pump; therefore, you should ask your gasoline retailer whether the gasoline contains MMT. It is even more important to look for gasolines without MMT in Canada, because 384 STARTING AND OPERATING MMT can be used at levels higher than those allowed in the United States. MMT is prohibited in Federal and California reformulated gasoline. Materials Added To Fuel All gasoline sold in the United States is required to contain effective detergent additives. Use of additional detergents or other additives is not needed under normal conditions and they would result in additional cost. Therefore, you should not have to add anything to the fuel. Fuel System Cautions CAUTION! Use the following guidelines to maintain your vehi- cle’s performance: (Continued) CAUTION! (Continued) • The use of leaded gas is prohibited by Federal law. Using leaded gasoline can impair engine perfor- mance, and damage the emission control system. • An out-of-tune engine, or certain fuel or ignition malfunctions, can cause the catalytic converter to overheat. If you notice a pungent burning odor or some light smoke, your engine may be out of tune or malfunctioning and may require immediate service. Contact your authorized dealer for service assistance. • The use of fuel additives, which are now being sold as octane enhancers, is not recommended. Most of these products contain high concentra- tions of methanol. Fuel system damage or vehicle performance problems resulting from the use of such fuels or additives is not the responsibility of the manufacturer. Intentional tampering with emissions control in civil penalties being assessed NOTE: systems can result against you. Carbon Monoxide Warnings WARNING! Carbon monoxide (CO) in exhaust gases is deadly. Follow the precautions below to prevent carbon monoxide poisoning. (Continued) STARTING AND OPERATING 385 WARNING! (Continued) • Do not inhale exhaust gases. They contain carbon monoxide, a colorless and odorless gas, which can kill. Never run the engine in a closed area, such as a garage, and never sit in a parked vehicle with the engine running for an extended period. If the vehicle is stopped in an open area with the engine running for more than a short period, adjust the ventilation system to force fresh, outside air into the vehicle. • Guard against carbon monoxide with proper maintenance. Have the exhaust system inspected every time the vehicle is raised. Have any abnor- mal conditions repaired promptly. Until repaired, drive with all side windows fully open. • Keep the liftgate closed when driving your vehicle to prevent carbon monoxide and other poisonous exhaust gases from entering the vehicle. 386 STARTING AND OPERATING ADDING FUEL Fuel Filler Cap (Gas Cap) The gas cap is located behind the fuel filler door, on the driver’s side of the vehicle. If the gas cap is lost or damaged, be sure the replacement cap has been designed for use with this vehicle. CAUTION! • Damage to the fuel system or emission control system could result from using an improper fuel cap (gas cap). A poorly fitting cap could let impu- rities into the fuel system. Also, a poorly fitting aftermarket cap can cause the “Malfunction Indi- cator Light (MIL)” to illuminate, due to fuel vapors escaping from the system. • A poorly fitting gas cap may cause the MIL to turn • To avoid fuel spillage and overfilling, do not “top on. off” the fuel tank after filling. Fuel Filler Cap WARNING! • Never have any smoking materials lit in or near the vehicle when the gas cap is removed or the tank filled. • Never add fuel when the engine is running.

STARTING AND OPERATING 387 • If the gas cap is not tightened properly, the MIL will come on. Be sure the gas cap is tightened every time the vehicle is refueled. Loose Fuel Filler Cap Message If the vehicle diagnostic system determines that the fuel filler cap is loose, improperly installed, or damaged, a gASCAP” message will display in the odometer or a “CHECK GASCAP” message will be displayed in the Electronic Vehicle Information Center (EVIC). Refer to “Electronic Vehicle Information Center (EVIC)” in “Un- derstanding Your Instrument Panel” for further review. Tighten the fuel filler cap until a “clicking” sound is heard. This is an indication that the fuel filler cap is properly tightened. Refer to “Onboard Diagnostic Sys- tem” further information. in “Maintaining Your Vehicle” for 388 STARTING AND OPERATING VEHICLE LOADING Certification Label As required by National Highway Traffic Safety Admin- istration regulations, your vehicle has a certification label affixed to the driver’s side door or B-Pillar. This label contains the month and year of manufacture, Gross Vehicle Weight Rating (GVWR), Gross Axle Weight Rating (GAWR) front and rear, and Vehicle Identification Number (VIN). A Month-Day-Hour (MDH) number is included on this label and indicates the month, day, and hour of manufacture. The bar code that appears on the bottom of the label is your VIN. Gross Vehicle Weight Rating (GVWR) The GVWR is the total permissible weight of your vehicle including driver, passengers, vehicle, options, trailer tongue weight, and cargo. The label also specifies maxi- mum capacities of front and rear axle systems (GAWR). Total load must be limited, so GVWR, and front and rear GAWR are not exceeded. Payload The payload of a vehicle is defined as the allowable load weight a truck or any given vehicle can carry, including the weight of the driver, all passengers, options and cargo. Gross Axle Weight Rating (GAWR) The GAWR is the maximum permissible load on the front and rear axles. The load must be distributed in the cargo area so that the GAWR of each axle is not exceeded. Each axle’s GAWR is determined by the components in the system with the lowest load carrying capacity (axle, springs, tires, or wheels). Heavier axles or suspension components, sometimes specified by purchasers for in- creased durability, does not necessarily increase the ve- hicle’s GVWR. Tire Size The tire size on the label represents the actual tire size on your vehicle. Replacement tires must be equal to the load capacity of this tire size. Rim Size This is the rim size that is appropriate for the tire size listed. Inflation Pressure This is the cold tire inflation pressure for your vehicle for all loading conditions up to full GAWR. Curb Weight The curb weight of a vehicle is defined as the total weight of the vehicle with all fluids, including vehicle fuel, at full capacity conditions, and with no occupants or cargo STARTING AND OPERATING 389 loaded into the vehicle. The front and rear curb weight values are determined by weighing your vehicle on a commercial scale before any occupants or cargo are added. Loading The actual total weight and the weight of the front and rear of your vehicle at the ground can best be determined by weighing it when it is loaded and ready for operation. The entire vehicle should first be weighed on a commer- cial scale to ensure that the GVWR has not been ex- ceeded. The weight on the front and rear of the vehicle should then be determined separately to be sure that the load is properly distributed over front and rear axle. Weighing the vehicle may show that the GAWR of either the front or rear axles has been exceeded, but the total load is within the specified GVWR. If so, weight must be shifted from front to rear, or rear to front, as appropriate until the specified weight limitations are met. Store the 390 STARTING AND OPERATING heavier items down low and be sure that the weight is distributed equally. Stow all loose items securely before driving. Improper weight distributions can have an adverse affect on the way your vehicle steers and handles, and the way the brakes operate. CAUTION! Do not load your vehicle any heavier than the GVWR or the maximum front and rear GAWR. If you do, parts on your vehicle can break, or it can change the way your vehicle handles. This could cause you to lose control. Also, overloading can shorten the life of your vehicle. TRAILER TOWING In this section, you will find safety tips and information on limits to the type of towing you can reasonably do with your vehicle. Before towing a trailer, carefully review this information to tow your load as efficiently and safely as possible. To maintain warranty coverage, follow the requirements and recommendations in this manual concerning ve- hicles used for trailer towing. Common Towing Definitions The following trailer towing related definitions will assist you in understanding the following information: Gross Vehicle Weight Rating (GVWR) The GVWR is the total allowable weight of your vehicle. This includes driver, passengers, cargo, and tongue weight. The total load must be limited so that you do not exceed the GVWR. Gross Trailer Weight (GTW) The GTW is the weight of the trailer plus the weight of all cargo, consumables, and equipment (permanent or tem- porary) loaded in or on the trailer in its ⬙loaded and ready for operation⬙ condition. The recommended way to measure GTW is to put your fully loaded trailer on a vehicle scale. The entire weight of the trailer must be supported by the scale. WARNING! (GTW) If the Gross Trailer Weight is 3,500 lbs (1 587 kg) or more, it is mandatory to use a weight- distributing hitch to ensure stable handling of your vehicle. If you use a standard weight- carrying hitch, you could lose control of your vehicle and cause an accident. STARTING AND OPERATING 391 Gross Combination Weight Rating (GCWR) The GCWR is the total permissible weight of your vehicle and trailer when weighed in combination. NOTE: The GCWR rating includes a 150 lbs (68 kg) allowance for the presence of a driver. Gross Axle Weight Rating (GAWR) The GAWR is the maximum capacity of the front and rear axles. Distribute the load over the front and rear axles evenly. Make sure that you do not exceed either front or rear GAWR. WARNING! It is important that you do not exceed the maximum front or rear GAWR. A dangerous driving condition can result if either rating is exceeded. You could lose control of the vehicle and have an accident. 392 STARTING AND OPERATING Tongue Weight (TW) The tongue weight is the downward force exerted on the hitch ball by the trailer. In most cases, it should not be less than 10% or more than 15% of the trailer load. You must consider this as part of the load on your vehicle. Frontal Area The frontal area is the maximum height and maximum width of the front of a trailer. Trailer Sway Control – Mechanical The trailer sway control is a telescoping link that can be installed between the hitch receiver and the trailer tongue that typically provides adjustable friction associated with the telescoping motion to dampen any unwanted trailer swaying motions while traveling. Weight-Carrying Hitch A weight-carrying hitch supports the trailer tongue weight, just as if it were luggage located at a hitch ball or some other connecting point of the vehicle. These kinds of hitches are the most popular on the market today and they are commonly used to tow small- and medium- sized trailers. Weight-Distributing Hitch A weight-distributing system works by applying lever- age through spring (load) bars. They are typically used for heavier loads, to distribute trailer tongue weight to the tow vehicle’s front axle and the trailer axle(s). When used in accordance with the manufacturers’ directions, it provides for a more level ride, offering more consistent steering and brake control thereby enhancing towing safety. The addition of a friction/hydraulic sway control also dampens sway caused by traffic and crosswinds and contributes positively to tow vehicle and trailer stability. Trailer sway control and a weight distributing (load equalizing) hitch are recommended for heavier Tongue Weights (TW) and may be required depending on Vehicle and Trailer configuration/loading to comply with Gross Axle Weight Rating (GAWR) requirements. WARNING! • An improperly adjusted Weight Distributing Hitch system may reduce handling, stability, brak- ing performance, and could result in an accident. • Weight Distributing Systems may not be compat- ible with Surge Brake Couplers. Consult with your hitch and trailer manufacturer or a reputable Rec- reational Vehicle dealer for additional information. STARTING AND OPERATING 393 Without Weight Distributing Hitch (Incorrect) 394 STARTING AND OPERATING With Weight Distributing Hitch (Correct) Improper Adjustment of Weight- Distributing Hitch (Incorrect) Trailer Hitch Classification Your vehicle is capable of towing trailers up to 2,000 lbs (907 kg) without added equipment or alterations to the standard equipment. Your vehicle may be factory equipped for safe towing of trailers weighing over 2,000 lbs (907 kg) with the optional Trailer Tow Prep Package. See your authorized dealer for package content. The following chart provides the industry standard for the maximum trailer weight a given trailer hitch class can tow. This should be used to assist you in selecting the correct trailer hitch for your intended towing condition. Refer to the “Trailer Towing Weights (Maximum Trailer Weight Ratings)” chart for the Max.

NOTE: The trailer tongue weight must be considered as part of the combined weight of occupants and cargo, and it should never exceed the weight referenced on the “Tire and Loading Information” placard. Refer to “Tire Safety Information” in “Starting and Operating” for further information. Trailer and Tongue Weight Always load a trailer with 60% to 65% of the weight in the front of the trailer. This places 10% to 15% of the Gross Trailer Weight (GTW) on the tow hitch of your vehicle. Loads balanced over the wheels or heavier in the rear can cause the trailer to sway severely side to side which will cause loss of control of vehicle and trailer. Failure to load trailers heavier in front is the cause of many trailer accidents. 398 STARTING AND OPERATING Never exceed the maximum tongue weight stamped on your bumper or trailer hitch. Consider the following items when computing the weight on the rear axle of the vehicle: • The tongue weight of the trailer. • The weight of any other type of cargo or equipment put in or on your vehicle. • The weight of the driver and all passengers. NOTE: Remember that everything put into or on the trailer adds to the load on your vehicle. Also, additional factory-installed options, or authorized dealer-installed options, must be considered as part of the total load on your vehicle. Refer to the “Tire and Loading Information” placard for the maximum combined weight of occupants and cargo for your vehicle. Towing Requirements To promote proper break-in of your new vehicle drive- train components, the following guidelines are recom- mended: CAUTION! • Do not tow a trailer at all during the first 500 miles (805 km) the new vehicle is driven. The engine, axle or other parts could be damaged. (Continued) CAUTION! (Continued) • Then, during the first 500 miles (805 km) that a trailer is towed, do not drive over 50 mph (80 km/h) and do not make starts at full throttle. This helps the engine and other parts of the vehicle wear in at the heavier loads. WARNING! Improper towing can lead to an injury accident. Follow these guidelines to make your trailer towing as safe as possible: (Continued) STARTING AND OPERATING 399 WARNING! (Continued) • Make certain that the load is secured in the trailer and that is will not shift during travel. When trailering cargo that is not fully secured, dynamic load shifts can occur that may be difficult for the driver to control. You could lose control of your vehicle and have an accident. • When hauling cargo, or towing a trailer, do not overload your vehicle or trailer. Overloading can cause a loss of control, poor performance, or dam- age to brakes, axle, engine, transmission, steering, suspension, chassis structure, or tires. • Safety chains must always be used between your vehicle and trailer. Always connect the chains to the frame or hook retainers of the vehicle hitch. Cross the chains under the trailer tongue and allow enough slack for turning corners. (Continued) 400 STARTING AND OPERATING WARNING! (Continued) • Vehicles with trailers should not be parked on a grade. When parking, apply the parking brake on the tow vehicle. Put the tow vehicle transmission in PARK. Always, block or ⴖchockⴖ the trailer wheels. • GCWR must not be exceeded. • Total weight must be distributed between the tow vehicle and the trailer such that the following four ratings are not exceeded: 1. GVWR 2. GTW 3. GAWR 4. Tongue weight rating for the trailer hitch uti- lized (This requirement may limit the ability to always achieve the 10% to 15% range of tongue weight as a percentage of total trailer weight). Towing Requirements – Tires − Do not attempt to tow a trailer while using a compact spare tire. − Proper tire inflation pressures are essential to the safe and satisfactory operation of your vehicle. Refer to “Tires – General Information” in “Starting and Oper- ating” for information on tire pressures and for proper tire inflation procedures. − Check the trailer tires for proper tire inflation pres- sures before trailer usage. − Check for signs of tire wear or visible tire damage before towing a trailer. Refer to “Tires – General Information” in “Starting and Operating” for informa- tion on tread wear indicators and for the proper inspection procedure. STARTING AND OPERATING 401 − Trailer brakes are recommended for trailers over 1,000 lbs (454 kg) and required for trailers in excess of 2,000 lbs (907 kg). CAUTION! If the trailer weighs more than 1,000 lbs (454 kg) loaded, it should have its own brakes, and they should be of adequate capacity. Failure to do this could lead to accelerated brake lining wear, higher brake pedal effort, and longer stopping distances. − When replacing tires, refer to “Tires – General Infor- mation” in “Starting and Operating” for information on replacement tires and for the proper tire replace- ment procedures. Replacing tires with a higher load carrying capacity will not increase the vehicle’s GVWR and GAWR limits. Towing Requirements – Trailer Brakes − Do not interconnect the hydraulic brake system or vacuum system of your vehicle with that of the trailer. This could cause inadequate braking and possible personal injury. − An electronically actuated trailer brake controller is required when towing a trailer with electronically actuated brakes. When towing a trailer equipped with a hydraulic surge actuated brake system, an electronic brake controller is not required. 402 STARTING AND OPERATING WARNING! • Do not connect trailer brakes to your vehicle’s hydraulic brake lines. It can overload your brake system and cause it to fail. You might not have brakes when you need them and could have an accident. • Towing any trailer will increase your stopping distance. When towing you should allow for addi- tional space between your vehicle and the vehicle in front of you. Failure to do so could result in an accident. Towing Requirements – Trailer Lights and Wiring Whenever you pull a trailer, regardless of the trailer size, stoplights and turn signals on the trailer are required for motoring safety. The Trailer Tow Package may include a four and seven- pin wiring harness. Use a factory approved trailer har- ness and connector. NOTE: Do not cut or splice wiring into the vehicles wiring harness. The electrical connections are all complete to the vehicle but you must mate the harness to a trailer connector. Refer to the following illustrations. STARTING AND OPERATING 403 1 — Female Pins 2 — Male Pin 3 — Ground Four-Pin Connector 4 — Park 5 — Left Stop/Turn 6 — Right Stop/Turn 1 — Battery 2 — Backup Lamps 3 — Right Stop/Turn 4 — Electric Brakes Seven-Pin Connector 5 — Ground 6 — Left Stop/Turn 7 — Running Lamps 404 STARTING AND OPERATING Towing Tips Before setting out on a trip, practice turning, stopping, and backing the trailer in an area located away from heavy traffic. Automatic Transmission The “D” range can be selected when towing. However, if frequent shifting occurs while in this range, you will want to activate the TOW/HAUL feature. Refer to “Au- tomatic Transmission” in “Starting and Operating” for further information. NOTE: Using the TOW/HAUL feature while operating the vehicle under heavy operating conditions will im- prove performance and extend transmission life by re- ducing excessive shifting and heat build up. This action will also provide better engine braking. If you REGULARLY tow a trailer for more than 45 min- utes of continuous operation, then change the automatic transmission fluid and filter according to the interval specified for “police, taxi, fleet, or frequent trailer tow- ing.” Refer to “Maintenance Schedule” for the proper maintenance intervals. TOW/HAUL To reduce potential for automatic transmission overheat- ing, press the TOW HAUL button when driving in hilly areas or shift the transmission to Drive position “2” on more severe grades. Refer to “Automatic Transmission” in “Starting and Operating” for further information. Electronic Speed Control – If Equipped − Do not use in hilly terrain or with heavy loads. − When using the speed control, if you experience speed drops greater than 10 mph (16 km/h), disengage until you can get back to cruising speed. − Use speed control in flat terrain and with light loads to maximize fuel efficiency. Cooling System To reduce potential for engine and transmission over- heating, take the following actions: − City Driving When stopped for short periods of time, shift the trans- mission into NEUTRAL and increase engine idle speed. − Highway Driving Reduce speed. − Air Conditioning Turn off temporarily. STARTING AND OPERATING 405 RECREATIONAL TOWING (BEHIND MOTORHOME, ETC.) Two-Wheel Drive Models Recreational towing is allowed ONLY if the driveshaft is removed. Towing with the rear wheels on the ground while the driveshaft is connected can result in severe transmission damage. WARNING! If the driveshaft is removed, the vehicle can roll even if the transmission is in PARK, which could cause serious injury or death. 406 STARTING AND OPERATING The parking brake must be firmly engaged and the wheels chocked during driveshaft removal and installa- tion. The parking brake must remain engaged unless the vehicle is securely and properly connected to the tow vehicle, or the driveshaft is completely reinstalled. See your authorized dealer for proper driveshaft removal and reinstallation procedures, including flange orienta- tion/alignment, use of thread-locking compound, proper bolt torque specifications, etc. Four-Wheel Drive Models The transfer case must be shifted into NEUTRAL and the transmission must be placed in PARK for recreational towing. The NEUTRAL selection button is located at the top of the transfer case switch. Shifts into and out of transfer case NEUTRAL can take place with the selector switch in any mode position. CAUTION! • The transmission must be in PARK position for recreational towing. Failure to follow these proce- dures can cause severe transmission and/or trans- fer case damage. • Internal damage to the transmission or transfer case will occur if a front or rear wheel lift is used when recreational towing. • Before recreational towing, perform the procedure outlined under “Shifting into NEUTRAL” to be certain that the transfer case is fully in NEUTRAL. Otherwise, internal damage will result. • Do not use a bumper mounted clamp-on tow bar on your vehicle. The bumper face bar will be damaged. WARNING! You or others could be injured if you leave the vehicle unattended with the transfer case in the NEUTRAL position without first fully engaging the parking brake. The transfer case NEUTRAL position disengages both the front driveshaft and rear drive- shaft from the powertrain and it will allow the vehicle to move, even if the transmission is in PARK. The parking brake should always be applied when the driver is not in the vehicle. Shifting into NEUTRAL Perform the following procedure to prepare your vehicle for recreational towing: 1. Bring the vehicle to a complete stop. 2. Turn OFF the engine. STARTING AND OPERATING 407 3. Turn the ignition switch to the ON position, but do not start the engine. 4. Press the brake pedal. 5.

Apply the parking brake. 408 STARTING AND OPERATING 13. Turn the ignition switch to the unlocked OFF posi- tion. 14. Shift the transmission into PARK. 15. Attach the vehicle to a tow vehicle with a tow bar. 16. Release the parking brake. NOTE: Steps 1 through 5 are requirements for shifting the transfer case. If these requirements are not met prior to depressing the NEUTRAL selection button or while the shift attempt is in process, then the NEUTRAL indicator light will flash continuously until all require- ments are met or until the NEUTRAL button is released. The ignition switch must be in the ON position for a shift to take place and for the position indicator lights to be operable. If the ignition switch is not in the ON position, the shift will not take place and no position indicator lights will be on or flashing. Flashing NEUTRAL position indicator light indicates that shift requirements have not been met. CAUTION! Damage to the transmission may occur if the trans- mission is shifted into PARK with the transfer case in NEUTRAL and the engine RUNNING. With the transfer case in NEUTRAL, ensure that the engine is OFF prior to shifting the transmission into PARK. Shifting Out of NEUTRAL Perform the following procedure to prepare your vehicle for normal usage: 1. Bring the vehicle to a complete stop. 2. Place the ignition switch in the LOCK position (if it has been moved or the engine has been started). 3. Turn the ignition switch to the ON position, but do not start the engine. 4. Press the brake pedal. 5. Shift the transmission into NEUTRAL. 6. Use the point of a ballpoint pen or similar object to press the recessed transfer case NEUTRAL button. Re- lease the NEUTRAL button after the NEUTRAL indicator light turns off (approximately one second). After the NEUTRAL button is released, the transfer case will shift to the position identified by the selector switch. 7. Start the engine. 8. Shift the transmission into DRIVE. 9. Set the parking brake. 10. Shift the transmission into PARK. STARTING AND OPERATING 409 NOTE: Steps 1 through 6 are requirements for shifting the transfer case. If these requirements are not met prior to depressing the NEUTRAL selection button or while the shift attempt is in process, then all of the mode position indicator lights will flash continuously until all requirements are met or until the NEUTRAL button is released. The ignition switch must be in the ON position for a shift to take place and for the position indicator lights to be operable. If the ignition switch in not in the ON position, the shift will not take place and no position indicator lights will be on or flashing. Flashing NEUTRAL position indicator light indicates that shift requirements have not been met.

Press the switch to turn on the Hazard Warning flasher. When the switch is activated, all directional turn signals will flash on and off to warn oncoming traffic of an emergency. Press the switch a second time to turn off the Hazard Warning flasher. This is an emergency warning system and it should not be used when the vehicle is in motion. Use it when your vehicle is disabled and it is creating a safety hazard for other motorists. When you must leave the vehicle to seek assistance, the Hazard Warning flasher will continue to operate even though the ignition switch is in the LOCK position. NOTE: With extended use, the Hazard Warning flasher may wear down your battery. IF YOUR ENGINE OVERHEATS In any of the following situations, you can reduce the potential for overheating your engine by taking the appropriate action. • On the highways — slow down. • In city traffic — while stopped, put transmission in NEUTRAL, but do not increase engine idle speed. CAUTION! Driving with a hot cooling system could damage your vehicle. If the temperature gauge reads “H,” pull over and stop the vehicle. Idle the vehicle with the air conditioner turned off until the pointer drops back into the normal range. If the pointer remains on the “H” and you hear continuous chimes, turn the engine off immediately and call for service. NOTE: There are steps that you can take to slow down an impending overheat condition: • If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this heat. • You can also turn the temperature control to maximum heat, the mode control to floor and the blower control to high. This allows the heater core to act as a supplement to the radiator and aids in removing heat from the engine cooling system. WARNING! You or others can be badly burned by hot engine coolant (antifreeze) or steam from your radiator. If you see or hear steam coming from under the hood, do not open the hood until the radiator has had time to cool. Never try to open a cooling system pressure cap when the radiator or coolant bottle is hot. JACKING AND TIRE CHANGING WHAT TO DO IN EMERGENCIES 413 WARNING! • Getting under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You could be crushed. Never get any part of your body under a vehicle that is on a jack. If you need to get under a raised vehicle, take it to a service center where it can be raised on a lift. • The jack is designed to use as a tool for changing tires only. The jack should not be used to lift the vehicle for service purposes. The vehicle should be jacked on a firm level surface only. Avoid ice or slippery areas. 414 WHAT TO DO IN EMERGENCIES Jack Location The scissor-type jack and tire changing tools are located in the cargo compartment behind a trim cover on the left rear trim panel. The latch is located at the bottom of the trim cover. Spare Tire Stowage The spare tire is stowed underneath the rear of the vehicle and is held in place by a cable winch mechanism. Spare Tire Removal Fit the jack handle extension over the drive nut located in the rear cargo area inside the vehicle. Use the lug wrench to rotate the nut counterclockwise until the spare is on the ground with enough slack in the cable to allow you to pull the tire out from under the vehicle. Jack Storage Location WHAT TO DO IN EMERGENCIES 415 When the spare is clear, tilt the retainer at the end of the cable, and pull it through the center of the wheel. Preparations For Jacking 1. Park the vehicle on a firm level surface as far from the edge of the roadway as possible. Avoid icy or slippery areas. WARNING! Do not attempt to change a tire on the side of the vehicle close to moving traffic. Pull far enough off the road to avoid being hit when operating the jack or changing the wheel. 2. Set the parking brake. Lowering/Raising Spare Tire CAUTION! The winch mechanism is designed for use with the jack extension tube only. Use of an air wrench or other power tools is not recommended and they can damage the winch. 416 WHAT TO DO IN EMERGENCIES 3. Place the shift lever into PARK (automatic transmis- sion) or REVERSE (manual transmission). 4. Turn the ignition to the LOCK position. 5. Turn on the Hazard Warning flasher. 6. Block both the front and rear of the wheel diagonally opposite of the jack- ing position. For example, if changing the right front tire, block the left rear wheel. NOTE: Passengers should not remain in the vehicle when the vehicle is being jacked. Jacking Instructions WARNING! Carefully follow these tire changing warnings to help prevent personal injury or damage to your vehicle: • Always park on a firm, level surface as far from the edge of the roadway as possible before raising the vehicle. • Block the wheel diagonally opposite the wheel to • Set the parking brake firmly and set an automatic transmission in PARK; a manual transmission in REVERSE. • Never start or run the engine with the vehicle on a be raised. jack.

Loosen (but do not remove) the wheel lug nuts by turning them to the left one turn while the wheel is still on the ground. 418 WHAT TO DO IN EMERGENCIES 4. Locate the jack as shown. For the front tires, place it (rearward) of the notch on the body weld seam behind wheel to be changed. For the rear tires, place it under the axle by the wheel to be changed. Position the jack handle on the jack. Do not raise the vehicle until you are sure the jack is fully engaged. Rear Jacking Location 5. Raise the vehicle by turning the jack screw to the right. Raise the vehicle only until the tire just clears the surface and enough clearance is obtained to install the spare tire. Minimum tire lift provides maximum stability. Front Jacking Location WARNING! Raising the vehicle higher than necessary can make the vehicle less stable and cause an accident. It could slip off the jack and hurt someone near it. Raise the vehicle only enough to remove the tire. 6. Remove the lug nuts and wheel. 7. Position the spare wheel/tire on the vehicle and install lug nuts with the cone-shaped end toward the wheel. Lightly tighten the nuts. To avoid the risk of forcing the vehicle off the jack, do not tighten the nuts fully until the vehicle has been lowered. 8. Lower the vehicle by turning the jack screw to the left, and remove the jack and wheel blocks. WHAT TO DO IN EMERGENCIES 419 9. Finish tightening the lug nuts. Push down on the wrench while tightening for increased leverage. Alternate nuts until each nut has been tightened twice. The correct wheel nut tightness is 95 ft lb (130 N·m). If in doubt about the correct tightness, have them checked with a torque wrench by your authorized dealer or at a service station. 10. Lower the jack to it’s fully closed position. WARNING! A loose tire or jack, thrown forward in a collision or hard stop, could endanger the occupants of the ve- hicle. Always stow the jack parts and the spare tire in the places provided. 11. Secure the tire, locations. jack, and tools in their proper 420 WHAT TO DO IN EMERGENCIES JUMP-STARTING PROCEDURES If your vehicle has a discharged battery it can be jump- started using a set of jumper cables and a battery in another vehicle or by using a portable battery booster pack. Jump-starting can be dangerous if done improperly so please follow the procedures in this section carefully. NOTE: When using a portable battery booster pack follow the manufacturer’s operating instructions and precautions. CAUTION! Do not use a portable battery booster pack or any other booster source with a system voltage greater than 12 Volts or damage to the battery, starter motor, alternator or electrical system may occur. WARNING! When temperatures are below the freezing point, electrolyte in a discharged battery may freeze. Do not attempt jump-starting because the battery could rup- ture or explode and cause personal injury. Battery temperature must be brought above the freezing point before attempting a jump-start. Preparations for Jump-Start The battery in your vehicle is located in the front of the engine compartment, behind the left headlight assembly. NOTE: The positive battery post is covered with a protective cap. Lift up on the cap to gain access to the positive battery post. WHAT TO DO IN EMERGENCIES 421 WARNING! • Take care to avoid the radiator cooling fan when- ever the hood is raised. It can start anytime the ignition switch is on. You can be injured by moving fan blades. • Remove any metal jewelry such as watch bands or bracelets that might make an inadvertent electrical contact. You could be seriously injured. • Batteries contain sulfuric acid that can burn your skin or eyes and generate hydrogen gas which is flammable and explosive. Keep open flames or sparks away from the battery. 1. Set the parking brake, shift the automatic transmission into PARK and turn the ignition to LOCK. 2. Turn off the heater, radio, and all unnecessary electri- cal accessories. Positive Battery Post 422 WHAT TO DO IN EMERGENCIES 3. If using a another vehicle to jump-start the battery, park the vehicle within the jumper cables reach, set the parking brake and make sure the ignition is OFF. WARNING! Do not allow vehicles to touch each other as this could establish a ground connection and personal injury could result. Jump-Starting Procedure WARNING! Failure to follow this procedure could result in per- sonal injury or property damage due to battery ex- plosion. CAUTION! Failure to follow these procedures could result in damage to the charging system of the booster vehicle or the discharged vehicle. 1. Connect the positive (+) end of the jumper cable to the positive (+) post of the discharged vehicle. 2. Connect the opposite end of the positive (+) jumper cable to the positive (+) post of the booster battery. 3. Connect the negative end (-) of the jumper cable to the negative (-) post of the booster battery. 4. Connect the opposite end of the negative (-) jumper cable to a good engine ground (exposed metal part of the discharged vehicle’s engine) away from the battery and the fuel injection system. WARNING! Do not connect the cable to the negative post (-) of the discharged battery. The resulting electrical spark could cause the battery to explode and could result in personal injury. 5. Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, and then start the engine in the vehicle with the discharged battery. Once the engine is started, remove the jumper cables in the reverse sequence: 6. Disconnect the negative (-) jumper cable from the engine ground of the vehicle with the discharged battery. 7. Disconnect the negative end (-) of the jumper cable from the negative (-) post of the booster battery. WHAT TO DO IN EMERGENCIES 423 8. Disconnect the opposite end of the positive (+) jumper cable from the positive (+) post of the booster battery. 9. Disconnect the positive (+) end of the jumper cable from the positive (+) post of the discharged vehicle. If frequent jump-starting is required to start your vehicle you should have the battery and charging system in- spected at your authorized dealer. CAUTION! Accessories that can be plugged into the vehicle power outlets draw power from the vehicle’s battery, even when not in use (i.e., cellular phones, etc.). Eventually, if plugged in long enough, the vehicle’s battery will discharge sufficiently to degrade battery life and/or prevent the engine from starting. 424 WHAT TO DO IN EMERGENCIES TOWING A DISABLED VEHICLE Two-Wheel Drive Vehicles If the rear wheels are on the ground (whether front wheels are raised or not), the vehicle may be towed with the transmission in NEUTRAL, if the speed does not exceed 30 mph (50 km/h) and the distance does not exceed 15 miles (25 km). If the vehicle must be towed at a speed OR distance exceeding these limits, it must be towed on a flatbed or with the driveshaft removed. Refer to “Recreational Tow- ing” in “Starting and Operating” for further information. CAUTION! Towing the vehicle with the rear wheels on the ground at more than 30 mph (50 km/h) or for more than 15 miles (25 km) can cause severe transmission damage. Such damage is not covered by the New Vehicle Limited Warranty. Four-Wheel Drive Vehicles The manufacturer recommends flatbed towing with all four wheels OFF the ground. If a flatbed is not available, the vehicle must be towed with all four wheels ON the ground, the transfer case in neutral, and the transmission in PARK (automatic trans- mission) or in gear (manual transmission). NOTE: Refer to “Recreational Towing” in “Starting and Operating” for further information. CAUTION! Towing a four-wheel drive vehicle with only two wheels on the ground (whether front wheels are raised, or rear wheels) is NOT permitted and can cause severe transmission and/or transfer case dam- age. Such damage is not covered by the New Vehicle Limited Warranty.

This system monitors the performance of the emissions, engine, and automatic transmission control systems. When these systems are operating properly, your vehicle will provide excellent performance and fuel economy, as well as engine emis- sions well within current government regulations. If any of these systems require service, the OBD II system will turn on the “Malfunction Indicator Light (MIL).” It will also store diagnostic codes and other information to assist your service technician in making repairs. Al- though your vehicle will usually be drivable and not need towing, see your authorized dealer for service as soon as possible. CAUTION! • Prolonged driving with the MIL on could cause further damage to the emission control system. It could also affect fuel economy and drivability. The vehicle must be serviced before any emissions tests can be performed. • If the MIL is flashing while the engine is running, severe catalytic converter damage and power loss will soon occur. Immediate service is required. Loose Fuel Filler Cap Message If the vehicle diagnostic system determines that the fuel filler cap is loose, improperly installed, or damaged, a “gASCAP” message will display in the odometer or a “CHECK gASCAP” message will be displayed in the Electronic Vehicle Information Center (EVIC). Refer to “Electronic Vehicle Information Center (EVIC)” in “Un- derstanding Your Instrument Panel” for further informa- tion. Tighten the gas cap until a ⬙clicking⬙ sound is heard. This is an indication that the gas cap is properly tight- ened. Press the odometer reset button to turn the message off. If the problem persists, the message will appear the next time the vehicle is started. This might indicate a damaged cap. If the problem is detected twice in a row, the system will turn on the MIL. Resolving the problem will turn the MIL light off. EMISSIONS INSPECTION AND MAINTENANCE PROGRAMS In some localities, it may be a legal requirement to pass an inspection of your vehicle’s emissions control system. Failure to pass could prevent vehicle registration. MAINTAINING YOUR VEHICLE 429 For states that require an Inspection and Mainte- nance (I/M), this check verifies the “Malfunction Indicator Light (MIL)” is functioning and is not on when the engine is running, and that the OBD II system is ready for testing. Normally, the OBD II system will be ready. The OBD II system may not be ready if your vehicle was recently serviced, recently had a dead battery or a battery replace- ment. If the OBD II system should be determined not ready for the I/M test, your vehicle may fail the test. Your vehicle has a simple ignition key-actuated test, which you can use prior to going to the test station. To check if your vehicle’s OBD II system is ready, you must do the following: 1. Turn the ignition switch to the ON position, but do not crank or start the engine. 430 MAINTAINING YOUR VEHICLE 2. If you crank or start the engine, you will have to start this test over. 3. As soon as you turn the ignition switch to the ON position, you will see the MIL symbol come on as part of a normal bulb check. 4. Approximately 15 seconds later, one of two things will happen: a. The MIL will flash for about 10 seconds and then return to being fully illuminated until you turn OFF the ignition or start the engine. This means that your vehicle’s OBD II system is not ready and you should not proceed to the I/M station. b. The MIL will not flash at all and will remain fully illuminated until you turn OFF the ignition or start the engine. This means that your vehicle’s OBD II system is ready and you can proceed to the I/M station. If your OBD II system is not ready, you should see your authorized dealer or repair facility. If your vehicle was recently serviced or had a battery failure or replacement, you may need to do nothing more than drive your vehicle as you normally would in order for your OBD II system to update. A recheck with the above test routine may then indicate that the system is now ready. Regardless of whether your vehicle’s OBD II system is ready or not, if the MIL is illuminated during normal vehicle operation you should have your vehicle serviced before going to the I/M station. The I/M station can fail your vehicle because the MIL is on with the engine running. REPLACEMENT PARTS Use of genuine MOPAR威 parts for normal/scheduled maintenance and repairs is highly recommended to en- sure the designed performance. Damage or failures caused by the use of non-MOPAR威 parts for maintenance and repairs will not be covered by the manufacturer’s warranty. DEALER SERVICE Your authorized dealer has the qualified service person- nel, special tools, and equipment to perform all service operations in an expert manner. Service Manuals are available which include detailed service information for your vehicle. Refer to these manuals before attempting any procedure yourself. Intentional tampering with emissions control NOTE: systems may void your warranty and could result in civil penalties being assessed against you. WARNING! You can be badly injured working on or around a motor vehicle. Only do service work for which you have the knowledge and the proper equipment. If you have any doubt about your ability to perform a service job, take your vehicle to a competent me- chanic. MAINTAINING YOUR VEHICLE 431 MAINTENANCE PROCEDURES The pages that follow contain the required maintenance services determined by the engineers who designed your vehicle. Besides those maintenance items specified in the fixed maintenance schedule, there are other components which may require servicing or replacement in the future.
