292 STARTING AND OPERATING Tire and Loading Information Placard

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 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. 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]).

STARTING AND OPERATING 293
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

STARTING AND OPERATING 295

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:

296 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 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

in higher

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.

STARTING AND OPERATING 297
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.

298 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 299

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).

300 STARTING AND OPERATING

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.

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.

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 301

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.

302 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 Certain models have sufficient tire-to-body clearance to allow use of tire chains. Install chains on rear tires only. Follow these recommendations to guard against damage and excessive tire and chain wear:

• Do not install tire chains or traction devices on ve- hicles with larger than P235/65R17 tires. Tires larger than this may not provide sufficient body clearance with chains or other traction devices. • Use SAE class “S” tire chains or traction devices only. • Follow tire chain manufacturer’s instructions for • Install chains snugly and tighten after 0.5 mile (1 km) • Do not exceed 30 mph (48 km/h), unless otherwise • Drive cautiously, avoiding large bumps, potholes and

extreme driving maneuvers.

STARTING AND OPERATING 303

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. 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. 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.

304 STARTING AND OPERATING The suggested rotation method is the “forward-cross” shown in the following diagram.

Tire Rotation

TIRE PRESSURE MONITOR SYSTEM (TPMS) The Tire Pressure Monitoring System (TPMS) will warn the driver of a low tire pressure based on the vehicle recommended cold tire pressure.

The tire pressure will vary with temperature by about 1 psi (7 kPa) for every 12°F (–11°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. Refer to “Tires – General Informa- tion” 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 pressure. The TPMS will warn the driver of a low tire pressure if the tire pressure falls below the low pressure warning threshold for any reason, including low temperature effects, or natural pressure loss through the tire.

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 recommended cold tire pressure. Once the low tire pressure warning has been illuminated, the tire pressure must be increased to the recommended cold tire pressure in order for the Tire Pressure Monitoring Telltale Light to be turned off. The system will automatically update and the Tire Pressure Monitoring Telltale Light will extinguish once the up- dated tire pressures have been received. The vehicle may need to be driven for up to 20 minutes above 15 mph (24 km/h) to receive this information.

STARTING AND OPERATING 305
For example, your vehicle has a recommended cold (parked for more than three hours) tire 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 tempera- ture drop to 20°F (-7°C) will decrease the tire pressure to approximately 24 psi (165 kPa). This tire pressure is sufficiently 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 have been inflated to the vehicle’s recommended cold tire pressure value.

306 STARTING AND OPERATING

CAUTION!

• The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures have been established for the tire size equipped on your vehicle. Undesirable system operation or sensor damage may result when using replacement equipment that is not of the same size, type, and/or style. Aftermarket wheels can cause sensor dam- age. 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 gauge, even if under-inflation has not reached the level to trigger illumination of the Tire Pressure Monitoring Telltale Light.

• 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 regularly NOTE: check the tire pressure in all of your tires, 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

STARTING AND OPERATING 307
A tire pressure monitoring sensor is located in the spare wheel, if the vehicle is equipped with a matching full-size spare wheel and tire assembly. The matching full-size spare tire can be used in place of any of the four road tires. A low spare tire will not cause the Tire Pressure Monitoring Telltale Light to illuminate, a warning mes- sage to appear, or the chime to sound.

The Tire Pressure Monitoring Telltale Light will illuminate in the instrument cluster, a “TIRE LOW PRESSURE” message will display in the instru- ment cluster for 60 seconds, and an audible chime will be activated, when one or more of the four active road tire pressures are low. 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. The system will automatically update and the Tire Pressure Monitor- ing Telltale Light will extinguish, once the updated tire

308 STARTING AND OPERATING pressures have been received. The vehicle may need to be driven for up to 20 minutes above 15 mph (24 km/h) to receive this information. The Tire Pressure Monitoring Telltale Light will flash on and off for 75 seconds, and remain on solid when a system fault is detected. In addition, a “CHECK TPM SYSTEM” message will be displayed for 75 seconds when a system fault is detected, and a chime will sound. If the ignition switch is cycled, this sequence will repeat, pro- viding 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 by any of the following: 1. Jamming due to electronic devices or driving next to facilities emitting the same Radio Frequencies as the TPM 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 TPM sensors. NOTE: • If your vehicle is equipped with a matching full-size spare wheel and tire assembly, it has a tire pressure monitoring sensor, and can be monitored by the Tire Pressure Monitoring System (TPMS). In the event that the matching full-size spare tire is swapped with a low pressure road tire, the next ignition switch cycle will still show the Tire Pressure Monitoring Telltale Light to be ON, a “TIRE LOW PRESSURE” message will be displayed in the instrument cluster for 60 seconds, and a chime to sound. Driving the vehicle for up to 20 minutes above 15 mph (24 km/h) will turn OFF the

Tire Pressure Monitoring Telltale Light as long as none of the road tires are below the low pressure warning threshold. • If your vehicle is not equipped with a matching full-size spare wheel and tire assembly, it does not have a tire pressure monitoring sensor in the spare tire. The TPMS will not be able to monitor the tire pressure. If you install the spare tire, in place of a road tire, that has a pressure below the low-pressure warning limit, upon the next ignition switch cycle, a chime will sound, a “TIRE LOW PRESSURE” message will be displayed in the instrument cluster for 60 seconds, and the Tire Pressure Monitoring Telltale Light will turn ON. After driving the vehicle for up to 20 minutes above 15 mph (25 km/h), the Tire Pressure Monitoring Telltale Light will flash on and off for 75 seconds and then remain on solid. In addition, a “CHECK TPM SYSTEM” message will be displayed for 75 seconds. For each subsequent ignition switch cycle, a chime will

STARTING AND OPERATING 309
sound, a “CHECK TPM SYSTEM” message will be displayed for 75 seconds, and the Tire Pressure Moni- toring Telltale Light will flash on and off for 75 seconds and then remain on solid. Once you repair or replace the original road tire, and reinstall it on the vehicle in place of the spare tire, the TPMS will update automati- cally and the Tire Pressure Monitoring 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 (24 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.

310 STARTING AND OPERATING It is particularly important, for you to regularly NOTE: check the tire pressure in all of your tires and to maintain the proper pressure. The Tire Pressure Monitor System (TPMS) consists of the following components: • Receiver Module • Four Tire Pressure Monitoring Sensors • Three Trigger Modules (mounted in three of the four • Various Tire Pressure Monitoring System Messages, which display in the Electronic Vehicle Information Center (EVIC), and a graphic displaying tire pressures

wheel wells)

• Tire Pressure Monitoring Telltale Light

A tire pressure monitoring sensor is located in the spare wheel, if the vehicle is equipped with a matching full-size spare wheel and tire assembly. The matching full-size spare tire can be used in place of any of the four road tires. A low spare tire will set the “SPARE LOW PRES- SURE” message, but it will not cause the Tire Pressure Monitoring 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 an au- dible chime will be activated, when one or more of the four active road tire pressures are low. In addition, the EVIC will display one or more Low Pressure messages (Left Front, Left Rear, Right Front, Right Rear) for three seconds, and a graphic display of the pressure value(s) with the low tire(s) “flashing.” Refer to “Electronic Ve- hicle Information Center (EVIC)” in “Understanding Your Instrument Panel” for further information.

NOTE: Your system can be set to display pressure units in PSI, kPa, or BAR.

Should a low tire condition occur on any of the four active road tire(s), you should stop as soon as possible, and inflate the low tire(s) that is “flashing” on the graphic display to the vehicle’s recommended cold tire pressure.

STARTING AND OPERATING 311
The system will automatically update, the graphic dis- play of the pressure value(s) will stop “flashing,” and the Tire Pressure Monitoring Telltale Light will extinguish once the updated tire pressure(s) have been received. The vehicle may need to be driven for up to 20 minutes above 15 mph (24 km/h) to receive this information. CHECK TPM SYSTEM Warning The Tire Pressure Monitoring Telltale Light will flash on and off for 75 seconds, and remain on solid when a system fault is detected. The system fault will also sound a chime. The EVIC will display a “CHECK TPM SYS- TEM” message for three seconds. This message is then followed by a graphic display, with “- -“ in place of the pressure value(s), indicating which Tire Pressure Moni- toring Sensor(s) is not being received.

312 STARTING AND OPERATING NOTE: Your system can be set to display pressure units in PSI, kPa, or BAR.

If the ignition switch 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, the ⬙CHECK TPM SYSTEM⬙

message will not be present, and a pressure value will be displayed instead of dashes. A system fault can occur by any of the following: 1. Jamming due to electronic devices or driving next to facilities emitting the same Radio Frequencies as the TPM 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 TPM sensors. The EVIC will also display a ⬙CHECK TPM SYSTEM⬙ message for three seconds when a system fault is de- tected possibly related to the trigger component. In this

case, the ⬙CHECK TPM SYSTEM⬙ message is then fol- lowed by a graphic display, with pressure values still shown. This indicates the pressure values are still being received from the TPM Sensors. However, the system still needs to be serviced as long as the ⬙CHECK TPM SYSTEM⬙ message exists. NOTE: • If your vehicle is equipped with a matching full-size spare wheel and tire assembly, it has a tire pressure monitoring sensor, and can be monitored by the Tire Pressure Monitoring System (TPMS). In the event that the matching full-size spare tire is swapped with a low pressure road tire, the next ignition switch cycle will still show the Tire Pressure Monitoring Telltale Light to be ON, a chime to sound, a Low Pressure message to appear in the EVIC, and the graphic display will still show the low tire pressure value “flashing.” Driving the vehicle for up to 20 minutes above 15 mph (24 km/h) will turn OFF the Tire Pressure Monitoring

STARTING AND OPERATING 313
Telltale Light as long as none of road tires are below the low pressure warning threshold. The EVIC will also display a “SPARE LOW PRESSURE” message, and the graphic display will show a tire pressure value in place of the “flashing” low tire pressure value. • If your vehicle is not equipped with a matching full-size spare wheel and tire assembly, it does not have a tire pressure monitoring sensor in the spare tire. The TPMS will not be able to monitor the tire pressure. If you install the spare tire in place of a road tire that has a pressure below the low-pressure warning limit, upon the next ignition switch cycle, the Tire Pressure Monitoring Telltale Light will remain ON, a chime will sound, and the EVIC will still display a “flashing” pressure value in the graphic display. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the Tire Pressure Monitoring Telltale Light will flash on and off for 75 seconds and then remain on solid. In addition, the EVIC will display a “CHECK TPM

SYSTEM⬙ message for three seconds and then display dashes (- -) in place of the pressure value. For each subsequent ignition switch cycle, a chime will sound, the Tire Pressure Monitoring Telltale Light will flash on and off for 75 seconds and then remain on solid, and the EVIC will display a ⬙CHECK TPM SYSTEM⬙ message for three seconds and then display dashes (- -) in place of the pressure value. Once you repair or replace the original road tire, and reinstall it on the vehicle in place of the spare tire, the TPMS will update automatically.

In addition, the Tire Pressure Monitoring 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 (24 km/h) in order for the TPMS to receive this information.

3.7 Engine

All engines (except 5.7L engines) are de- signed to meet all emissions regulations and provide excellent fuel economy and performance when using high-quality un- leaded “regular” gasoline having an oc- tane rating of 87. The use of premium gasoline is not recommended, as it will not provide any benefit over regular gasoline in these engines. 5.7L Engine

The 5.7L 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

STARTING AND OPERATING 315
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. 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.

316 STARTING AND OPERATING Reformulated Gasoline Many areas of the country require the use of cleaner burning gasoline referred to as “Reformulated Gasoline.” Reformulated gasoline contains oxygenates, and are spe- cifically blended to reduce vehicle emissions and im- prove air quality. The manufacturer supports the use of reformulated gaso- line. Properly blended reformulated gasoline 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 gasoline containing Methanol. Use of these blends may result in starting and drivability problems and may damage critical fuel system com- ponents.

Problems that result from using Methanol/gasoline 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.

STARTING AND OPERATING 317

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 if the gasoline contains MMT. It is even more important to look for gasoline 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.

318 STARTING AND OPERATING 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.

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.

CAUTION! (Continued)

• 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.

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

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. This is in violation of most state and federal fire regula- tions and will cause the malfunction indicator light to turn on. • A fire may result if gasoline is pumped into a portable container that is inside of a vehicle. You could be burned. Always place gas containers on the ground while filling.

NOTE: • When the fuel nozzle “clicks” or shuts off, the fuel

tank is full.

STARTING AND OPERATING 321

• Tighten the gas cap about one-quarter turn until you hear one click. This is an indication that the cap is properly tightened. • If the gas cap is not tighten 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 “CHECK GASCAP” message will be displayed in the EVIC (Electronic Vehicle Information Center). Refer to “Electronic Vehicle Information Center (EVIC)” in “Un- derstanding Your Instrument Panel” for further informa- tion. 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.

322 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 323
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

324 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 trailer 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. 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.

STARTING AND OPERATING 325

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.

Trailer Tongue Weight (TW) The TW 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.

326 STARTING AND OPERATING 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 hitch system works by applying leverage 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’ direc- tions, 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 cross- winds, and contributes positively to tow vehicle and

trailer stability. Trailer sway control and a weight- distributing (load equalizing) hitch are recommended for heavier trailer 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 hitch systems may not be compatible with Surge Brake Couplers. Consult with your hitch and trailer manufacturer or a reputable Recreational Vehicle dealer for addi- tional information.

Refer to local laws for maximum trailer towing speeds.

NOTE: The trailer tongue weight must be considered as part of the combined weight of occupants and cargo, and should never exceed the weight referenced on the Tire and Loading Information placard. The addition of pas- sengers and cargo may require reducing trailer tongue

load and Gross Trailer Weight (GTW). Redistributing cargo (to the trailer) may be necessary to avoid exceeding Rear Gross Axle Weight Rating (GAWR) of 3,200 lbs (1 451 kg).

Trailer And Trailer 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.

STARTING AND OPERATING 331

Consider the following items when computing the weight on the front/rear axles of the vehicle: • The trailer 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.

332 STARTING AND OPERATING 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 further information. Towing Requirements To promote proper break-in of your new vehicle drive- train components, the following guidelines are recom- mended.

CAUTION!

• Avoid towing a trailer for the first 500 miles (805 km) of vehicle operation. Doing so may dam- age your vehicle. • During the first 500 miles (805 km) of trailer

towing, limit your speed to 50 mph (80 km/h).

Perform the maintenance listed in the “Maintenance Schedule.” Refer to “Maintenance Schedule” for the proper maintenance intervals. When towing a trailer, never exceed the GAWR or GCWR ratings.

WARNING!

Improper towing can lead to an injury accident. Follow these guidelines to make your trailer towing as safe as possible: • 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.

(Continued)

STARTING AND OPERATING 333

WARNING! (Continued)

• 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. Trailer tongue weight rating for the trailer hitch utilized (This requirement may limit the ability to always achieve the 10% to 15% range of tongue weight as a percentage of total trailer weight).

WARNING! (Continued)

• 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 hook retainers of the vehicle hitch. Cross the chains under the trailer tongue and allow enough slack for turning corners. • 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. For four-wheel drive vehicles, make sure the transfer case is not in NEUTRAL. Always, block or ⴖchockⴖ the trailer wheels.

(Continued)

334 STARTING AND OPERATING 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 proper inspection procedure.

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

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).

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)

STARTING AND OPERATING 335

WARNING! (Continued)

• Towing any trailer will increase your stopping distance. When towing, you should allow for ad- ditional space between your vehicle and the ve- hicle 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 includes a seven–pin connector at the rear of the vehicle and a four-pin harness located under the rear bumper. The four-pin harness must be unclipped before use. Use a factory-approved trailer harness and connector.

336 STARTING AND OPERATING The electrical connections are all complete to the vehicle but you must mate the harness to a trailer connector. Refer to the following illustrations.

Towing Tips Before setting out on a trip, practice turning, stopping and backing the trailer in an area away from heavy traffic. Automatic Transmission The DRIVE range can be selected when towing. How- ever, if frequent shifting occurs while in this range, the TOW/HAUL mode (if equipped), or a lower gear range, should be selected. NOTE: Using the TOW/HAUL mode (if equipped) or selecting a lower gear range (using the Electronic Range Select (ERS) feature) while operating the vehicle under heavy operating conditions, will improve performance and extend transmission life by reducing excessive shift- ing and heat buildup. This action will also provide better engine braking.

STARTING AND OPERATING 337
The transmission fluid and filter should be changed if you REGULARLY tow a trailer for more than 45 minutes of continuous operation. Refer to “Maintenance Sched- ule” for the proper maintenance intervals. NOTE: Check the transmission fluid level before towing (5.7L engine). 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.

338 STARTING AND OPERATING 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.

SNOW PLOW Snow plows, winches, and other aftermarket equipment should not be added to the front end of your vehicle. The airbag crash sensors may be affected by the change in the front end structure. The airbags could deploy unexpect- edly or could fail to deploy during a collision.

WARNING!

Do not add a snow plow, winches, or any other aftermarket equipment to the front of your vehicle. This could adversely affect the functioning of the airbag system and you could be injured.

RECREATIONAL TOWING (BEHIND MOTORHOME, ETC.)

Towing – 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.

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 flange orientation/alignment, use of thread-locking compound, proper bolt torque specifications, etc.

IF YOUR ENGINE OVERHEATS In any of the following situations, you can reduce the potential for overheating by taking the appropriate ac- tion. • On the highways — Slow down. • In city traffic — While stopped, shift the transmission to NEUTRAL, but do not increase the engine idle speed.

346 WHAT TO DO IN EMERGENCIES HAZARD WARNING FLASHERS The Hazard Warning flasher switch is located on the switch bank just above 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 run down your battery.

CAUTION!

Driving with a hot cooling system could damage your vehicle. If the temperature gauge reads HOT (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 HOT (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.

WHAT TO DO IN EMERGENCIES 347

• 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.

348 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 be used 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 passenger side compartment, behind the second row seat.

Jack Storage Location

Spare Tire Stowage The spare tire is stowed under the rear of the vehicle by means of a cable winch mechanism. To remove or stow the spare, use the jack handle to rotate the “spare tire drive” nut. The nut is located under a plastic cover at the center-rear of the cargo floor area, just inside the liftgate opening.

CAUTION!

Do not use power tools to winch the tire up or down. Impact type tools can damage the winch mechanism.

Front Jacking Location

Rear Jacking Location

For the rear axle, place it under the axle near the wheel to be changed. Ensure the jack is closest to the inside of the wheel when jacking on the rear axle. Do not raise the vehicle until you are sure the jack is fully engaged.

5. Raise the vehicle by turning the jack screw clockwise. 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.

354 WHAT TO DO IN EMERGENCIES

WARNING!

Raising the vehicle higher than necessary can make the vehicle less stable. 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 counter- clockwise, 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

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.

11. Secure the tire, jack, and tools in their proper loca- tions. NOTE: A tire should be stowed with the “beauty” side up. Storing the tire upside down may result in scratching or damage to the wheel face. Continue winching up the tire until you hear the winch “ratchet” three times.

Double check to ensure the tire is snug against the underbody of the vehicle. Damage to the winch cable may result if the vehicle is driven with the tire loose.

WHAT TO DO IN EMERGENCIES 355
NOTE: When using a portable battery booster pack follow the manufacturer’s operating instructions and precautions.

WARNING!

CAUTION!

Do not use power tools to winch the tire up or down. Impact-type tools may damage the winch mecha- nism.

12. Reinstall the plastic plug into the floor of the cargo area.

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.

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 freezing point before attempting a jump-start.

356 WHAT TO DO IN EMERGENCIES Preparations for Jump-Start The battery in your vehicle is located in the front of the engine compartment, behind the left headlight assembly.

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.

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.

WHAT TO DO IN EMERGENCIES 357

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.

358 WHAT TO DO IN EMERGENCIES

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.

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. 10. Reinstall the air intake duct. 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.

EMERGENCY TOW HOOKS — IF EQUIPPED If your vehicle is equipped with tow hooks, there will be one in the rear and two mounted on the front of the vehicle. The rear hook will be located on the driver’s side of the vehicle. NOTE: For off-road recovery, it is recommended to use both of the front tow hooks to minimize the risk of damage to the vehicle.

CAUTION!

Tow hooks are for emergency use only, to rescue a vehicle stranded off road. Do not use tow hooks for tow truck hookup or highway towing. You could damage your vehicle.

WHAT TO DO IN EMERGENCIES 359

WARNING!

Stand clear of vehicles when pulling with tow hooks. Tow straps and chains may break, causing serious injury.

TOWING A DISABLED VEHICLE

Two-Wheel Drive Models Only Provided the transmission is operable, tow only in NEU- TRAL at speeds not exceeding 30 mph (48 km/h), for distances of not more than 15 miles (24 km).

CAUTION!

Towing at more than 30 mph (48 km/h) or for more than 15 miles (24 km), can cause severe transmission damage. Such damage is not covered by the New Vehicle Limited Warranty.

360 WHAT TO DO IN EMERGENCIES If the transmission is not operable, or the vehicle must be towed faster than 30 mph (48 km/h) or farther than 15 miles (24 km), remove the driveshaft or tow with all four wheels OFF the ground. Acceptable methods are to tow the vehicle on a flatbed, or with one end of the vehicle raised and the other end on a towing dolly.

Four-Wheel Drive Models Only The manufacturer requires towing your vehicle with all four wheels OFF the ground using a flatbed.

CAUTION!

Towing this vehicle using any other method could result in extensive damage to the transfer case and/or transmission. Such damage is not covered by the New Vehicle Limited Warranty.

ONBOARD DIAGNOSTIC SYSTEM – OBD II Your vehicle is equipped with a sophisticated onboard diagnostic system called OBD II. 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.

MAINTAINING YOUR VEHICLE 365

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 After fuel is added, the vehicle diagnostic system can determine if the fuel filler cap is loose, improperly installed, or damaged. A “CHECK GASCAP” message will be displayed in the EVIC. Refer to “Electronic Vehicle
