Definition


The vehicle B-Pillar is a structural member of the body located between the front and rear door (of a four-door vehicle) running from the sill to the roof. Cold tire inflation pressure is defined as the tire pressure after the vehicle has not been driven for at least 3 hours, or driven less than 1 mile (1.6 km) after sitting for a three hour period. Inflation pressure is measured in units of PSI (pounds per square inch) or KPa (kilopascals). The maximum inflation pressure is the maximum permissible cold tire inflation pressure for this tire. The max inflation pressure is molded into the sidewall. Vehicle manufacturer’s recommended tire inflation pressure as shown on the tire placard. A paper label permanently attached to the vehicle showing the vehicle’s loading capacity, the original equipment tire size and the recommended inflation pressure.

Tire Placard Location


Tire and Loading Information Placard


This placard tells you important information about the: 1) number of people that can be carried in the vehicle 2) total weight your vehicle can carry 3) tire size designed for your vehicle 4) cold tire inflation pressures for the front, rear, and spare tires.


Loading The vehicle maximum load on the tire must not exceed the load carrying capacity of the tire on your vehicle. You will not exceed the tire’s load carrying capacity if you adhere to the loading conditions, tire size, and cold tire inflation pressures specified on the Tire and Loading Information placard and in the “Vehicle Loading” section of this manual. NOTE: Under a maximum loaded vehicle condition, gross axle weight ratings (GAWRs) for the front and rear axles must not be exceeded. For further information on GAWRs, vehicle loading, and trailer towing, refer to “Vehicle Loading” in this section. To determine the maximum loading conditions of your vehicle, locate the statement “The combined weight of


STARTING AND OPERATING 335
occupants and cargo should never exceed XXX lbs or XXX kg” on the Tire and Loading Information placard. The combined weight of occupants, cargo/luggage and trailer tongue weight (if applicable) should never exceed the weight referenced here. 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. 3. Subtract the combined weight of the driver and pas- sengers from XXX lbs or XXX kg.


336 STARTING AND OPERATING 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.


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).

Safety


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

lems. You could lose control of your vehicle.


(Continued)


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 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

STARTING AND OPERATING 339
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.


340 STARTING AND OPERATING


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.


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.


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).


STARTING AND OPERATING 341


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.


342 STARTING AND OPERATING


WARNING!


CAUTION!


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.


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).


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.


WARNING!


Fast spinning tires can be dangerous. Forces gener- ated by excessive wheel speeds may cause tire dam- age or failure. A tire could explode and injure some- one. 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.


Tread Wear Indicators Tread wear indicators are in the original equipment tires to help you in determining when your tires should be replaced.


STARTING AND OPERATING 343


1 — Worn Tire 2 — New Tire 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.


344 STARTING AND OPERATING


CAUTION!


WARNING!


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.


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.


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


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.


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.


STARTING AND OPERATING 345


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)


346 STARTING AND OPERATING


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 “Class S” chains or other traction aids that meet SAE Type “S” specifications. NOTE: Chains must be the proper size for the vehicle as recommended by the chain manufacturer.


CAUTION!


To avoid damage to your vehicle, tires or chains, observe the following precautions: • 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. • Install chains as tightly as possible and then • Do not exceed 45 mph (72 km/h). • Drive cautiously and avoid severe turns and large • Do not drive for a prolonged period on dry pave-

ment.


(Continued)


CAUTION! (Continued)


• Observe the tire chain manufacturer’s instructions on method of installation, operating speed, and conditions for usage. Always use the lower sug- gested operating speed of the chain manufacturer if different than the speed recommended by the manufacturer.


These cautions apply to all chain traction devices, includ- ing link and cable (radial) chains. Tire chain use is permitted only on the rear tires. NOTE: The use of class “S” chains is permitted with P235/65R17 and P225/75R16 tires.


STARTING AND OPERATING 347


CAUTION!


Do not use tire chains on vehicles equipped with tires other than P235/65R17 and P225/75R16 tires. There may not be adequate clearance for the chains and you are risking structural or body damage to your vehicle.


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. 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.


348 STARTING AND OPERATING


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. More frequent rotation is permissible if desired. The reasons for any rapid or unusual wear should be corrected prior to rotation being performed. NOTE: The premium Tire Pressure Monitor System will automatically locate the pressure values displayed in the correct vehicle position following a tire rotation. The suggested rotation method is the “forward-cross” shown in the following diagram.


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. 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.


STARTING AND OPERATING 349
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.


350 STARTING AND OPERATING 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.


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.”


STARTING AND OPERATING 351


• 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


352 STARTING AND OPERATING 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.


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.

FUEL REQUIREMENTS


3.7L Engine


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.


4.0L Engine


The 4.0L engine is designed to meet all emissions regulations and provide satisfac- tory fuel economy and performance when using high quality unleaded gasoline hav- ing an octane range of 87 to 89. The manu- facturer recommends the use of 89 octane for optimum performance. 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 experience these symptoms, try another brand of gasoline before consid- ering service for the vehicle.


STARTING AND OPERATING 359
Over 40 auto manufacturers worldwide have issued and endorsed consistent gasoline specifications (the World- wide Fuel Charter, WWFC) to 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.


360 STARTING AND OPERATING 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


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 or not his/her gasoline contains MMT.


STARTING AND OPERATING 361
It is even more important to look for gasolines without MMT in Canada, because MMT can be used at levels higher than those allowed in the United States. MMT is prohibited in Federal and California reformu- lated 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 would result in additional cost. Therefore you should not have to add anything to the fuel.


362 STARTING AND OPERATING Fuel System Cautions


CAUTION!


Follow these guidelines to maintain your vehicle’s performance: • 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.


(Continued)


CAUTION! (Continued)


• 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.


NOTE: systems can result against you.


Intentional tampering with emissions control in civil penalties being assessed


STARTING AND OPERATING 363


WARNING! (Continued)


• 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.


Carbon Monoxide Warnings


WARNING!


Carbon monoxide (CO) in exhaust gases is deadly. Follow the precautions below to prevent carbon monoxide poisoning: • 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.

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

NOTE: • When the fuel nozzle “clicks” or shuts off, the fuel • Tighten the gas cap about one quarter turn until you hear one click. This is an indication that the cap is properly tightened.


STARTING AND OPERATING 365


• 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” in “Understand- ing Your Instrument Panel” for further information. 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.

366 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 367
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


368 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. Refer to “Vehicle Loading/Vehicle Certification Label” in Starting and Operating” for fur- ther information.


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!


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 369


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. Refer to “Vehicle Loading/Vehicle Certifica- tion Label” in Starting and Operating” for further infor- mation.


370 STARTING AND OPERATING


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.


Tongue Weight 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 multiplied by the maximum width of the front of a trailer. Trailer Sway Control 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 kind 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 manufacturer’s directions, it pro- vides 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, and 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 additional information.

376 STARTING AND OPERATING 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 from 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.


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 • The weight of the driver and all passengers.


put in or on your vehicle.


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 “Tire Safety Information/Tire and Loading Information Placard” in “Starting and Operat- ing” 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)


STARTING AND OPERATING 377


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)


378 STARTING AND OPERATING


WARNING! (Continued)


• Make certain that the load is secured in the trailer and 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)


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 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 the proper inspection procedure.


− When replacing tires, refer to “Tires – General Infor- mation” in “Starting and Operating” for proper tire


STARTING AND OPERATING 379
replacement 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.


− Trailer brakes are recommended for trailers over 1,000 lbs (454 kg) and required for trailers in excess of 2,000 lbs (907 kg).


380 STARTING AND OPERATING


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.


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.


(Continued)


WARNING! (Continued)


• 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, stop lights and turn signals on the trailer are required for motoring safety. The trailer tow package may include a four-pin and seven-pin wiring harness. Use a factory approved trailer harness 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.

382 STARTING AND OPERATING Towing Tips Before setting out on a trip, practice turning, stopping and backing up the trailer in an area away from heavy traffic. Automatic Transmission The “D” range can be selected when towing. However, if frequent shifting occurs while in this range, the “TOW/ HAUL” button (if equipped) or a lower gear range should be selected. NOTE: Using the “TOW/HAUL” button (3.7L engine) or “4” range (4.0L engine) while operating the vehicle under heavy operating conditions will improve perfor- mance and extend transmission life by reducing exces- sive shifting and heat build up. This action will also provide better engine braking. The automatic transmission fluid and filter should be changed if you regularly tow a trailer for more than


45 minutes of continuous operation. Refer to “Mainte- nance Schedule” for the proper maintenance intervals. TOW/HAUL – If Equipped 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 Transmis- sion” 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.

386 WHAT TO DO IN EMERGENCIES HAZARD WARNING FLASHER The Hazard Warning Flasher switch is located on the lower switch bank below the climate controls.


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 should not be used when the vehicle is in motion. Use it when your vehicle is disabled and is creating a safety hazard for other motorists. If it is necessary to leave the vehicle to go for service, the Hazard Warning flasher will continue to operate with the ignition key removed and the vehicle locked. 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.


388 WHAT TO DO IN EMERGENCIES JACKING AND TIRE CHANGING


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.


Jack Location The scissor-type jack and tire changing tools are located in the left rear trim panel behind the second row seat.


Jack Storage Location


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. 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.


WHAT TO DO IN EMERGENCIES 389


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.


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. Avoid icy or slippery areas.


Lowering/Raising Spare Tire


390 WHAT TO DO IN EMERGENCIES


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. 3. Place the shift lever into PARK. 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.

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.


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 the 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. 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


WHAT TO DO IN EMERGENCIES 393
wheel nut tightness is 95 ft lbs (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 its 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.

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


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.


394 WHAT TO DO IN EMERGENCIES 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!


Do not attempt jump-starting if the battery is frozen. It could rupture or explode and cause personal injury.


Positive Battery Post


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.


WHAT TO DO IN EMERGENCIES 395
3. If using 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.


396 WHAT TO DO IN EMERGENCIES


CAUTION!


WARNING!


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.


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.


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.
