reduce engine power and apply the brake of the appro- priate wheel(s) to counteract the sway of the trailer. TSC will become active automatically once an excessively swaying trailer is recognized. Note that TSC cannot stop all trailers from swaying. Always use caution when towing a trailer and follow the trailer tongue weight recommendations. Refer to “Trailer Towing” in this sec- tion for further information. When TSC is functioning, the “ESC Activation/Malfunction Indicator Light” will flash, the engine power may be reduced and you may feel the brakes being applied to individual wheels to attempt to stop the trailer from swaying. TSC is disabled when the ESC system is in the “Partial Off” mode.WARNING!
If TSC activates while driving, slow the vehicle down, stop at the nearest safe location, and adjust the trailer load to eliminate trailer sway.
450 STARTING AND OPERATING Hill Start Assist (HSA) The HSA system is designed to assist the driver when starting a vehicle from a stop on a hill. HSA will maintain the level of brake pressure the driver applied for a short period of time after the driver takes their foot off of the brake pedal. If the driver does not apply the throttle during this short period of time, the system will release brake pressure and the vehicle will roll down the hill. The system will release brake pressure in proportion to the amount of throttle applied as the vehicle starts to move in the intended direction of travel. HSA Activation Criteria The following criteria must be met in order for HSA to activate: • Vehicle must be stopped. • Vehicle must be on a 6% (approximate) grade or
greater hill.
• Gear selection matches vehicle uphill direction (i.e., vehicle facing uphill is in forward gear; vehicle back- ing uphill is in REVERSE gear).
HSA will work in REVERSE and all forward gears when the activation criteria have been met. The system will not activate if the vehicle is placed in NEUTRAL or PARK.
WARNING!
There may be situations on minor hills with a loaded vehicle, or while pulling a trailer, when the system will not activate and slight rolling may occur. This could cause a collision with another vehicle or object. Always remember the driver is responsible for brak- ing the vehicle.
Towing With HSA HSA will provide assistance when starting on a grade when pulling a trailer.
WARNING!
• If you use a trailer brake controller with your trailer, your trailer brakes may be activated and deactivated with the brake switch. If so, when the brake pedal is released, there may not be enough brake pressure to hold the vehicle and trailer on a hill and this could cause a collision with another vehicle or object behind you. In order to avoid rolling down the hill while resuming acceleration, manually activate the trailer brake prior to releas- ing the brake pedal. Always remember the driver is responsible for braking the vehicle.

STARTING AND OPERATING 451
WARNING! (Continued)
• HSA is not a parking brake. If you stop the vehicle on a hill without putting the transmission in PARK and using the parking brake, it will roll down the hill and could cause a collision with another ve- hicle or object. Always remember to use the park- ing brake while parking on a hill, and that the driver is responsible for braking the vehicle.

When the throttle is released very quickly, Ready Alert Braking applies a small amount of brake pressure. This brake pressure will not be noticed by the driver. The brake system uses this brake pressure to allow a fast brake response if the driver applies the brakes. Rain Brake Support — If Equipped Rain Brake Support may improve braking performance in wet conditions. It will periodically apply a small amount of brake pressure to remove any water buildup on the front brake rotors. It only functions when the windshield wipers are in the LO or HI mode, it does not function in the intermittent mode. When Rain Brake Support is active, there is no notification to the driver and no driver interaction is required.
Hill Descent Control Switch
HDC is intended for low speed off road driving while in 4WD Low Range. HDC maintains vehicle speed while
descending hills during various driving situations. HDC controls vehicle speed by actively controlling the brakes. HDC has three states: 1. Off (feature is not enabled and will not activate). 2. Enabled (feature is enabled and ready but activation conditions are not met, or driver is actively overriding with brake or throttle application).
3. Active (feature is enabled and actively controlling

ESC Activation/Malfunction Indicator Light And ESC OFF Indicator Light
The “ESC Activation/Malfunction Indicator Light” in the instrument cluster will come on when the ignition switch is cycled to the ON/ RUN position. It should go out with the engine running. If the “ESC Activation/Malfunction Indicator Light” comes on continuously with the engine running, a malfunction has been detected in the ESC system. If this light remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers) at speeds greater than 30 mph (48 km/h), see your autho- rized dealer as soon as possible to have the problem diagnosed and corrected. The “ESC Activation/Malfunction Indicator Light” (lo- cated in the instrument cluster) starts to flash as soon as the tires lose traction and the ESC system becomes active. The “ESC Activation/Malfunction Indicator Light” also flashes when TCS is active. If the “ESC Activation/ Malfunction Indicator Light” begins to flash during ac- celeration, ease up on the accelerator and apply as little throttle as possible. Be sure to adapt your speed and driving to the prevailing road conditions. NOTE: • The “ESC Off
Indicator Light” and the “ESC Activation/Malfunction Indicator Light” come on mo- mentarily each time the ignition switch is turned to the ON/RUN position.
• Each time the ignition is cycled to the ON/RUN position, the ESC system will be ON even if it was cycled off previously. • The ESC system will make buzzing or clicking sounds when it is active. This is normal; the sounds will stop when ESC becomes inactive following the maneuver that caused the ESC activation.
The “ESC OFF Indicator Light” indicates the Electronic Stability Control (ESC) is partially off or full off.

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.
STARTING AND OPERATING 469
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.
470 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 lbs (68 kg) = 750 lbs (340 kg), and 1400 lbs (635 kg) – 750 lbs (340 kg) = 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.
NOTE: • If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. The follow- ing table shows examples on how to calculate total load, cargo/luggage, and towing capacities of your vehicle with varying seating configurations and num- ber 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).

WARNING!
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
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: • Safety • Economy • Ride Comfort And Vehicle Stability
WARNING!
• Improperly inflated tires are dangerous and can cause collisions. • Under-inflation increases tire flexing and can re- sult in over-heating and tire failure. • Over-inflation reduces a tire’s ability to cushion shock. Objects on the road and chuckholes can cause damage that result in tire failure. • Over-inflated or under-inflated tires can affect ve- hicle handling and can fail suddenly, resulting in loss of vehicle control. • Unequal tire pressures can cause steering prob- lems. You could lose control of your vehicle.
(Continued)
WARNING! (Continued)
• Unequal tire pressures from one side of the vehicle 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 resulting in higher fuel consump- tion. 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 473
stability of the vehicle and can produce a feeling of sluggish response or over responsiveness in the steering. NOTE: • Unequal tire pressures from side to side may cause • Unequal tire pressure from side to side may cause theerratic and unpredictable steering response.
vehicle to drift left or right.
Tire Inflation Pressures The proper cold tire inflation pressure is listed on the driver’s side B-Pillar or rear edge of the driver’s side door. At least once a month: • Check and adjust tire pressure with a good quality pocket-type pressure gauge. Do not make a visual
474 STARTING AND OPERATING
judgement when determining proper inflation. Tires may look properly inflated even when they are under- inflated. • Inspect tires for signs of tire wear or visible damage.
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 the valve stem.
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 infla- tion pressure 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 and 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 your authorized tire dealer or original equipment vehicle dealer for recommended safe operat- ing speeds, loading and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maxi- mum load is dangerous. The added strain on your tires could cause them to fail. You could have a serious collision. Do not drive a vehicle loaded to the maximum capacity at continuous speeds above 75 mph (120 km/h).
Radial Ply Tires
STARTING AND OPERATING 475
WARNING!
Combining radial ply tires with other types of tires on your vehicle will cause your vehicle to handle poorly. The instability could cause a collision. Al- ways use radial ply tires in sets of four. Never combine them with other types of tires.
Tire Repair If your tire becomes damaged, it may be repaired if it meets the following criteria: • The tire has not been driven on when flat. • The damage is only on the tread section of your tire • The puncture is no greater than ¼⬙ (6 mm).
(sidewall damage is not repairable).
476 STARTING AND OPERATING Consult an authorized tire dealer for tire repairs and additional information. Damaged Run Flat tires, or Run Flat tires that have experienced a loss of pressure should be replaced imme- diately with another Run Flat tire of identical size and service description (Load Index and Speed Code). All Season Tires — If Equipped All Season tires provide traction for all seasons (spring, summer, fall and winter). Traction levels may vary be- tween different all season tires. All season tires can be identified by the M+S, M&S, M/S or MS designation on the tire sidewall. Use all season tires only in sets of four; failure to do so may adversely affect the safety and handling of your vehicle. Summer Or Three Season Tires — If Equipped Summer tires provide traction in both wet and dry conditions, and are not intended to be driven in snow or
on ice. If your vehicle is equipped with summer tires, be aware these tires are not designed for winter or cold driving conditions. For more information, contact a au- thorized dealer. Summer tires do not contain the “all season” designation or “mountain/snowflake” symbol on the tire sidewall. Use summer tires only in sets of four; failure to do so may adversely affect the safety and handling of your vehicle. Snow Tires Some areas of the country require the use of snow tires during the winter. Snow tires can be identified by a mountain/snowflake symbol on the tire sidewall. If you need snow tires, select tires equivalent in size and type to the original equipment tires. Use snow tires only in sets of four; failure to do so may adversely affect the safety and handling of your vehicle.
Snow tires generally have lower speed ratings than what was originally equipped with your vehicle and should not be operated at sustained speeds over 75 mph (120 km/h). For speeds above 75 mph (120 km/h) refer to original equipment or an authorized tire dealer for recommended safe operating speeds, loading and cold tire inflation pressures. While studded tires improve performance on ice, skid and traction capability on wet or dry surfaces may be poorer than that of non-studded tires. Some states pro- hibit studded tires; local laws should be checked before using these tire types. Spare Tire Matching Original Equipped Tire And Wheel — If Equipped Your vehicle may be equipped with a spare tire and wheel equivalent in look and function to the original equipment tire and wheel found on the front or rear axle of your vehicle. This spare tire may be used in the tire

rotation for your vehicle. If your vehicle has this option, refer to an authorized tire dealer for the recommended tire rotation pattern. Compact Spare Tire — If Equipped The compact spare is for temporary emergency use only. You can identify if your vehicle is equipped with a compact spare by looking at the spare tire description on the Tire and Loading Information Placard located on the driver’s side door opening or on the sidewall of the tire. Compact spare tire descriptions begin with the letter “T” or “S” preceding the size designation. Example: T145/ 80D18 103M. T, S = Temporary Spare Tire Since this tire has limited tread life, the original equip- ment tire should be repaired (or replaced) and reinstalled on your vehicle at the first opportunity.478 STARTING AND OPERATING 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 tire. Do not install more than one compact spare tire and wheel on the vehicle at any given time.
WARNING!
Compact spares are for temporary emergency use only. With these spares, do not drive more than 50 mph (80 km/h). Temporary use spares 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.
Full Size Spare — If Equipped The full size spare is for temporary emergency use only. This tire may look like the originally equipped tire on the
front or rear axle of your vehicle, but it is not. This spare tire may have limited tread life. When the tread is worn to the tread wear indicators, the temporary use full size spare tire needs to be replaced. Since it is not the same as your original equipment tire, replace (or repair) the original equipment tire and reinstall on the vehicle at the first opportunity. Limited-Use Spare — If Equipped The limited-use spare tire is for temporary emergency use only. This tire is identified by a label located on the limited-use spare wheel. This label contains the driving limitations for this spare. This tire may look like the original equipped tire on the front or rear axle of your vehicle, but it is not. Installation of this limited-use spare tire affects vehicle handling. Since it is not the same as your original equipment tire, replace (or repair) the original equipment tire and reinstall on the vehicle at the first opportunity.
WARNING!
Limited-use spares are for emergency use only. In- stallation of this limited-use spare tire affects vehicle handling. With this tire, do not drive more than the speed listed on the limit-use spare wheel. Keep inflated to the cold tire inflation pressures listed on your Tire and Loading Information Placard located on the driver’s side B-Pillar or the rear edge of the driver’s side door. Replace (or repair) the original equipment tire at the first opportunity and reinstall it on your vehicle. Failure to do so could result in loss of vehicle control.
Tire Spinning When stuck in mud, sand, snow, or ice conditions, do not spin your vehicle’s wheels above 30 mph (48 km/h) or for longer than 30 seconds continuously without stop- ping.
STARTING AND OPERATING 479
Refer to “Freeing A Stuck Vehicle” in “What To Do In Emergencies” for further information.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) for more than 30 seconds continu- ously 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.

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. Refer to “Replacement Tires” in this section for further infor- mation. Life Of Tire The service life of a tire is dependent upon varying factors including, but not limited to: • Driving style • Tire pressure • Distance driven • Performance tires, tires with a speed rating of V or higher, and summer tires typically have a reduced tread life. Rotation of these tires per the vehicle main- tenance schedule is highly recommended.
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 a collision 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. 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
STARTING AND OPERATING 481
Information placard or the Vehicle Certification Label for the size designation of your tire. The Load Index and Speed Symbol for your tire will be found on the original equipment tire sidewall. See the Tire Sizing Chart ex- ample found in the Tire Safety Information section of this manual for more information relating to the Load Index and Speed Symbol of a tire. It is recommended to replace the two front tires or two rear tires as a pair. Replacing just one tire can seriously affect your vehicle’s handling. If you ever replace a wheel, make sure that the wheel’s specifications match those of the original wheels. It is recommended you contact your authorized tire dealer or original equipment dealer with any questions you may have on tire specifications or capability. Failure to use equivalent replacement tires may adversely affect the safety, handling, and ride of your vehicle.482 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 a collision 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, other 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 a collision.
(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 (TRACTION DEVICES) Use of traction devices require sufficient tire-to-body clearance. Follow these recommendations to guard against damage. • Traction device must be of proper size for the tire, as
recommended by the traction device manufacturer.
• Install on Rear Tires Only • Due to limited clearance, the Security Chain Company (SCC) Super Z6 low profile traction device or equiva- lent is recommended on P265/60R18 or 265/50R20
tires.WARNING!
Using tires of different size and type (M+S, Snow) between front and rear axles can cause unpredictable handling. You could lose control and have a collision.
CAUTION!
To avoid damage to your vehicle or tires, observe the following precautions: • Because of restricted traction device clearance be- tween tires and other suspension components, it is

STARTING AND OPERATING 483
CAUTION! (Continued)
important that only traction devices in good condi- tion are used. Broken devices can cause serious damage. Stop the vehicle immediately if noise occurs that could indicate device breakage. Remove the damaged parts of the device before further use. • Install device as tightly as possible and then re- tighten after driving about ½ mile (0.8 km). • Do not exceed 30 mph (48 km/h). • Drive cautiously and avoid severe turns and large bumps, especially with a loaded vehicle. • Do not drive for a prolonged period on dry pavement. • Observe the traction device manufacturer’s instruc- tions on the method of installation, operating speed, and conditions for use. Always use the suggested operating speed of the device manufac- turer’s if it is less than 30 mph (48 km/h). • Do not use traction devices on a compact spare tire.
484 STARTING AND OPERATING TIRE ROTATION RECOMMENDATIONS The tires on the front and rear of your vehicle 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. Refer to the “Maintenance Schedule” for the proper main- tenance 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) 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. NOTE: It is particularly important, for you to regularly 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 • Various Tire Pressure Monitoring System Messages, which display in the Electronic Vehicle Information Center (EVIC), and a graphic displaying tire pressures
STARTING AND OPERATING 485
• Tire Pressure Monitoring Telltale Light The Tire Pressure Monitoring System (TPMS) will warn the driver of a low tire pressure based on the vehicle recommended cold tire placard pressure. The tire pressure will vary with temperature by about 1
psi (7 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. 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.486 STARTING AND OPERATING 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 placard 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 updated 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. For example, your vehicle has a recommended cold (parked for more than three hours) tire 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 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.
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 equip- ment 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 al- ways reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the Tire Pressure Monitoring Sensor.
NOTE: • The TPMS is not intended to replace normal tire care and maintenance, or to provide warning of a tire failure or condition.
STARTING AND OPERATING 487
while adjusting your tire pressure.
• 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.
488 STARTING AND OPERATING Premium System — If Equipped The Tire Pressure Monitor System (TPMS) uses wireless technology with wheel rim-mounted electronic sensors to monitor tire pressure levels.

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 in a different color on the graphic display to the vehicle’s recommended cold tire pressure displayed in the ⬙Inflate Tire to XXX⬙ message.
490 STARTING AND OPERATING The system will automatically update, the graphic dis- play of the pressure value(s) will return to its original color 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 infor- mation. SERVICE 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 “SERVICE TPM SYS- TEM” message for a minimum of five seconds. This message is then followed by a graphic display, with “- -“ in place of the pressure value(s), indicating which Tire Pressure Monitoring Sensor(s) is not being received. NOTE: Your system can be set to display pressure units in PSI or kPa.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 ⬙SERVICE 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 ⬙SERVICE TPM SYSTEM⬙ message for a minimum of five seconds when a system fault is detected possibly related to an incorrect sensor location fault. In this case, the ⬙SERVICE TPM SYSTEM⬙ message is then followed by a graphic display, with pressure values still shown. This indicates the pressure values are still being received from the TPM Sensors but they may not be located in the correct vehicle position. However, the system still needs to be serviced as long as the ⬙SERVICE TPM SYSTEM⬙ message exists. NOTE: There is no 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 pressure value in the different color graphic display and an ⬙Inflate to XXX kPa⬙ message will be displayed. After driving the vehicle
STARTING AND OPERATING 491
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 “SERVICE TPM SYSTEM⬙ message for five 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 ⬙SERVICE TPM SYSTEM⬙ message for five seconds and then dis- play 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 to492 STARTING AND OPERATING be driven for up to 20 minutes above 15 mph (24 km/h) in order for the TPMS to receive this information.

3.6L Engine — If Equipped
This engine is 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. 5.7L Engine — If Equipped
This engine is designed to meet all emis- sions regulations and provide satisfactory fuel economy and performance when us- ing high-quality unleaded gasoline having
an octane range of 87 to 89. The manufacturer recom- mends 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 experi- ence these symptoms, try another brand of gasoline before considering service for the vehicle. Over 40 auto manufacturers worldwide have issued and endorsed consistent gasoline specifications (the World- wide Fuel Charter, WWFC) which define fuel properties necessary to deliver enhanced emissions, performance, and durability for your vehicle. The manufacturer recom- mends the use of gasolines that meet the WWFC speci- fications if they are available.
STARTING AND OPERATING 493
Reformulated Gasoline Many areas of the country require the use of cleaner burning gasoline referred to as “Reformulated Gasoline.” Reformulated gasoline contain 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 Ethanol. Fuels blended with oxygenates may be used in your vehicle.
494 STARTING AND OPERATING
CAUTION!
DO NOT use gasoline containing Methanol or gaso- line containing more than 10% Ethanol. Use of these blends may result in starting and drivability prob- lems, damage critical fuel system components, cause emissions to exceed the applicable standard, and/or cause the “Malfunction Indicator Light” to illumi- nate. Pump labels should clearly communicate if a fuel contains greater than 10% Ethanol.
Problems that result from using gasoline containing Methanol or gasoline containing more than 10% Ethanol are not the responsibility of the manufacturer and may not be covered under New Vehicle Limited Warranty.
E-85 Usage In Non-Flex Fuel Vehicles Non-Flex Fuel Vehicles (FFV) are compatible with gaso- line containing 10% ethanol (E10). Gasoline with higher ethanol content may void the New Vehicle Limited 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).STARTING AND OPERATING 495
therefore, you should ask your gasoline retailer whether the gasoline contains MMT. MMT is prohibited in Federal and California reformulated gasoline. Materials Added To Fuel All gasoline sold in the United States is required to contain effective detergent additives. Use of additional detergents or other additives is not needed under normal conditions and they would result in additional cost. Therefore, you should not have to add anything to the fuel.• 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 Methylcyclopentadienyl Manganese Tricarbonyl (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 emissions 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,
CAUTION! (Continued)
Most of these products contain high concentrations of methanol. Fuel system damage or vehicle perfor- mance problems resulting from the use of such fuels or additives is not the responsibility of the manufacturer.
NOTE: Intentional tampering with the emissions control system can result in civil penalties being assessed against you.
496 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 emissions 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 ser- vice. Contact your authorized dealer for service assistance. • The use of fuel additives, which are now being sold as octane enhancers, is not recommended.

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. • Guard against carbon monoxide with proper main- tenance. Have the exhaust system inspected every

FLEXIBLE FUEL (3.6L ENGINE ONLY) — IF EQUIPPED
E-85 General Information The information in this section is for Flexible Fuel ve- hicles only. These vehicles can be identified by a unique fuel filler door label that states Ethanol (E-85) or Un- leaded Gasoline Only. This section only covers those subjects that are unique to these vehicles. Please refer to the other sections of this manual for information on features that are common between Flexible Fuel and gasoline-only powered vehicles.
498 STARTING AND OPERATING
CAUTION!
Only vehicles with the E-85 fuel filler door label can operate on E-85.
E-85 Badge
Ethanol Fuel (E-85) E-85 is a mixture of approximately 85% fuel ethanol and 15% unleaded gasoline.
WARNING!
Ethanol vapors are extremely flammable and could cause serious personal injury. Never have any smok- ing materials lit in or near the vehicle when remov- ing the fuel filler tube cap (gas cap) or filling the tank. Do not use E-85 as a cleaning agent and never use it near an open flame.
Fuel Requirements If your vehicle is E-85 compatible, it will operate on unleaded gasoline with an octane rating of 87, or E-85
fuel, or any mixture of these two fuels.For best results, a refueling pattern that avoids alternat- ing between E-85 and unleaded gasoline is recom- mended. When you do switch fuel types it is recommended that: • You do not add less than 5 gallons (19 Liters) when • You drive the vehicle immediately after refueling for at
refueling.
least 5 miles (8 km).
Observing these precautions will avoid possible hard starting and/or significant deterioration in driveability during warm up. NOTE: • Use seasonally adjusted E-85 fuel (ASTM D5798). With non-seasonally adjusted E-85 fuel, you may experience hard starting and rough idle following start up even if the above recommendations are followed, especially when the ambient temperature is below 32°F (0°C).
STARTING AND OPERATING 499
• Some additives used in regular gasoline are not fully compatible with E-85 and may form deposits in your engine. To eliminate driveability issues that may be caused by these deposits, a supplemental gasoline additive, such as MOPAR® Injector Cleanup or Techron may be used.
Selection Of Engine Oil For Flexible Fuel Vehicles (E-85) And Gasoline Vehicles FFV vehicles operated on E-85 require specially formu- lated engine oils. These special requirements are included in MOPAR® engine oils, and in equivalent oils meeting Chrysler Specification MS-6395. The manufacturer only recommends engine oils that are API Certified and meet the requirements of Material Standard MS-6395. MS-6395
contains additional requirements, developed during ex- tensive fleet testing, to provide additional protection to Chrysler Group LLC engines. Use MOPAR® or an equivalent oil meeting the specification MS-6395.500 STARTING AND OPERATING Starting The characteristics of E-85 fuel make it unsuitable for use when ambient temperatures fall below 0°F (-18°C). In the range of 0°F (-18°C) to 32°F (0°C), you may experience an increase in the time it takes for your engine to start, and a deterioration in driveability (sags and/or hesitations) until the engine is fully warmed up. NOTE: Use of the engine block heater (if equipped) is beneficial for E-85 startability when the ambient tempera- ture is less than 32°F (0°C). Cruising Range Because E-85 fuel contains less energy per gallon/liter than gasoline, you will experience an increase in fuel consumption. You can expect your miles per gallon (mpg)/miles per liter and your driving range to decrease by about 30%, compared to gasoline operation.
Replacement Parts Many components in your Flexible Fuel Vehicle (FFV) are designed to be compatible with ethanol. Always be sure that your vehicle is serviced with correct ethanol com- patible parts.
CAUTION!
Replacing fuel system components with non-ethanol compatible components can damage your vehicle.
Maintenance
CAUTION!
Do not use ethanol mixture greater than 85% in your vehicle. It will cause difficulty in cold starting and may affect drivability.

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 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 and cargo. The label also specifies maximum 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 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 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 vehi- cle’s GVWR.
STARTING AND OPERATING 505
Tire Size The tire size on the Vehicle Certification 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 loaded into the vehicle. The front and rear curb weight
506 STARTING AND OPERATING 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 insure that the GVWR has not been exceeded. 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 the front and rear axle. Weigh- ing 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 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 effect 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 the New Vehicle Limited Warranty coverage, follow the requirements and recommendations in this manual concerning vehicles 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 further 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 a collision.
Gross Combination Weight Rating (GCWR) The GCWR is the total permissible weight of your vehicle and trailer when weighed in combination. 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 information.
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 a collision.
Tongue Weight (TW) The tongue weight is the downward force exerted on the hitch ball by the trailer. In most cases it should not be less than 10% 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 can be a mechanical telescoping link that can be installed between the hitch receiver and the trailer tongue that typically provides adjustable fric- tion associated with the telescoping motion to dampen any unwanted trailer swaying motions while traveling. If equipped, the electronic Trailer Sway Control (TSC) recognizes a swaying trailer and automatically applies individual wheel brakes and/or reduces engine power to attempt to eliminate the trailer sway. Weight-Carrying Hitch A weight-carrying hitch supports the trailer tongue weight, just as if it were luggage located at a hitch ball or some other connecting point of the vehicle. These kinds of hitches are the most popular on the market today and they are commonly used to tow small and medium sized trailers.

Weight-Distributing Hitch A weight-distributing system works by applying lever- age through spring (load) bars. They are typically used for heavier loads to distribute trailer tongue weight to the tow vehicle’s front axle and the trailer axle(s). When used in accordance with the 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, braking performance, and could result in a collision. • Weight Distributing Systems may not be compat- ible with Surge Brake Couplers. Consult with your hitch and trailer manufacturer or a reputable Rec- reational Vehicle dealer for additional information.

information. The addition of passengers 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 3,700 lbs (1 678 kg).
512 STARTING AND OPERATING Trailer Hitch Receiver Cover Removal (Summit Models) — If Equipped Your vehicle may be equipped with a trailer hitch re- ceiver cover, this must be removed to access the trailer hitch receiver (if equipped). This hitch receiver cover is located at the bottom center of the rear fascia. 1. Turn the two locking retainers located at the bottom of the hitch receiver cover a 1/4 turn counterclockwise. NOTE: Use a suitable tool such as a coin in the slot of the locking retainer if needed for added leverage.

2. Pull the bottom of the cover outward (towards you), pull downwards to disengage the tabs located at the top of the hitch receiver cover.
STARTING AND OPERATING 513
NOTE: Be sure to engage all tabs of the hitch receiver cover in the bumper fascia prior to installation. Trailer And Tongue Weight Always load a trailer with 60% of the weight in the front of the trailer. This places 10% of the 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 the vehicle and trailer. Failure to load trailers heavier in front is the cause of many trailer collisions. Never exceed the maxi- mum tongue weight stamped on your trailer hitch.Hitch Receiver Cover
To reinstall the hitch receiver cover after towing repeat the procedure in reverse order.
514 STARTING AND OPERATING
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 dealer-installed options must be considered as part of the total load on your vehicle. Refer to “Tire Safety Information/Tire and Loading In- formation Placard” in “Starting and Operating” for fur- ther information. Towing Requirements To promote proper break-in of your new vehicle drive- train components, the following guidelines are recom- mended.
CAUTION!
• Do not tow a trailer at all during the first 500 miles (805 km) the new vehicle is driven. The engine, axle or other parts could be damaged.
(Continued)
CAUTION! (Continued)
• Then, during the first 500 miles (805 km) that a trailer is towed, do not drive over 50 mph (80 km/h) and do not make starts at full throttle. This helps the engine and other parts of the vehicle wear in at the heavier loads.
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.
STARTING AND OPERATING 515
WARNING!
Improper towing can lead to a collision. 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 a collision. • 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

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
WARNING!
• Do not connect trailer brakes to your vehicle’s hydraulic brake lines. It can overload your brake system and cause it to fail. You might not have brakes when you need them and could have an accident. • Towing any trailer will increase your stopping distance. When towing you should allow for addi- tional space between your vehicle and the vehicle in front of you. Failure to do so could result in an accident.
518 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. • 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 1,653 lbs (750 kg).
Towing Requirements — Trailer Lights And Wiring Whenever you pull a trailer, regardless of the trailer size, stoplights and turn signals on the trailer are required for motoring safety. The Trailer Tow Package may include a four- and seven- pin wiring harness. Use a factory approved trailer har- ness and connector. NOTE: Do not cut or splice wiring into the vehicles wiring harness. The electrical connections are all complete to the vehicle but you must mate the harness to a trailer connector. Refer to the following illustrations.

520 STARTING AND OPERATING Towing Tips Before setting out on a trip, practice turning, stopping and backing the trailer up in an area away from heavy traffic. Automatic Transmission The DRIVE range can be selected when towing. The transmission controls include a strategy to avoid frequent shifting when towing. However, if frequent shifting does occur while in DRIVE, you can use the Paddle Shift switches to manually select a lower gear. NOTE: Using a lower gear while operating the vehicle under heavy loading conditions, will improve perfor- mance and extend transmission life by reducing exces- sive shifting and heat buildup. This action will also provide better engine braking.
Paddle Shift Mode • When using the Paddle Shift switches, select
the highest gear that allows for adequate performance and avoids frequent downshifts. For example, choose “5” if the desired speed can be maintained. Choose “4” or “3” if needed to maintain the desired speed. • To prevent excess heat generation, avoid continuous driving at high RPM. Reduce vehicle speed as neces- sary to avoid extended driving at high RPM. Return to a higher gear or vehicle speed when grade and road conditions allow.
Electronic Speed Control — If Equipped • Do not use in hilly terrain or with heavy loads. • When using the speed control, if you experience speed drops greater than 10 mph (16 km/h), disengage until you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System To reduce potential for engine and transmission over- heating, take the following actions: City Driving When stopped for short periods of time, shift the trans- mission into NEUTRAL and increase engine idle speed. Highway Driving Reduce speed. Air Conditioning Turn off temporarily.
