FOUR-WHEEL DRIVE OPERATION

MP1522 Command-TracT Transfer Case — If Equipped

Operating Information & Precautions The Command-Tract transfer case provides four posi- tions: † 2 (rear) wheel drive high range.

† 4-wheel drive high range. † Neutral. † 4-wheel drive low range. This transfer case is intended to be driven in the 2-wheel drive position (2WD) for normal street and highway conditions such as dry hard surfaced roads. When additional traction is required, select the transfer case 4WD Lock position or 4WD Low position. This position locks the front driveshaft and rear driveshaft together and forces the front and rear wheels to rotate at the same speed. Use the transfer case Neutral (N) position for recreational towing only. Refer to “Recreational Towing” in this section for specific procedures on shifting into and out of Neutral (N).

STARTING AND OPERATING 293

CAUTION!

WARNING!

† Do not attempt to make a shift while only the front wheels or rear wheels are spinning. The MP1522 Command-Tract transfer case is not equipped with a synchronizer and therefore the speed of the front driveshaft and rear drive- shaft must be equal for the shift to take place. Shifting while only the front wheels or rear wheels are spinning can cause damage to the transfer case. † The 4WD Lock position and 4WD Low position are in- tended for loose or slippery road surfaces only. Driving in these positions on dry hard surfaced roads may cause increased tire wear and damage to the driveline compo- nents. † When operating your vehicle in 4WD LOW, the engine speed is approximately three times that of the 2WD posi- tion or 4WD LOCK position at a given road speed. Take care not to over-speed the engine and do not exceed 25 mph (40 km/h). † Proper operation of 4-wheel drive vehicles depends on tires of equal size, type, and circumference on each wheel. Any difference in tire size can cause damage to the transfer case.

† You or others could be injured if you leave the vehicle unattended with the transfer case in the Neutral (N) position without first fully engaging the parking brake. The transfer case Neutral (N) position disengages both the front driveshaft and rear driveshaft from the powertrain and it will allow the vehicle to move despite the transmission position. The parking brake should always be applied when the driver is not in the vehicle. † Always engage the parking brake when powering down the vehicle if the “SERV 4WD” light is illuminated. Not engaging the parking brake may allow the vehicle to roll, which may cause personal injury. † Since 4-wheel drive provides improved traction, there is a tendency to exceed safe turning and stopping speeds. Do not go faster than road condi- tions permit. You or others could be injured.

4WD Control Switch

2WD Rear Wheel Drive High Range - Normal street and highway driving. Dry hard surfaced roads.

4WD Lock 4-Wheel-Drive High Range - Locks the front driveshaft and rear driveshaft together and forces the front and rear wheels to rotate at the same speed. Additional traction for loose or slippery road surfaces only. 4WD Low 4-Wheel-Drive Low Range - Low speed 4-wheel drive that locks the front driveshaft and rear driveshaft to- gether and forces the front and rear wheels to rotate at the same speed. Additional traction and maximum pulling power for loose or slippery road surfaces only. Do not exceed 25 mph (40 km/h). This position allows engine starting without depressing the clutch pedal on vehicles equipped with a manual transmission. Refer to “Clutch Interlocking Ignition System” under “Manual Transmis- sion” or to “Starting Procedures” in this section for details.

N Neutral - Disengages both the front driveshaft and rear driveshaft from the powertrain. To be used for flat towing behind another vehicle. Refer to “Recreational Towing” in this section for more information. Transfer Case Position Indicator Lights The 4WD indicator lights are located in the instrument cluster. The “N” (Neutral) indicator light is located on the 4WD Control Switch. If there is no indicator light on or flashing, the transfer case position is 2-wheel drive (2WD). If the indicator light is on, the desired position (4WD LOCK, 4WD LOW, or NEUTRAL) has been ob- tained. If One or More Shift Requirements are not met: † An indicator light will flash. † The transfer case will not shift.

STARTING AND OPERATING 295

NOTE: The “SERV 4WD” warning light monitors the electric shift 4WD system. If this light remains on after engine start up, or it illuminates during driving, it means that the 4WD system is not functioning properly and that service is required. Shifting Procedures

If any of the requirements to select a new NOTE: transfer case position have not been met, the transfer case will not shift, the indicator light for the previous position will remain ON, and the newly selected position indica- tor light will continue to flash until all the requirements for the selected position have been met. To retry a shift, move the 4WD Control Switch back to the original position, make certain all shift requirements have been met, wait five (5) seconds, and try the shift again.

296 STARTING AND OPERATING

2WD to 4WD Lock Move the 4WD Control Switch to the desired position. Shifts between 2WD and 4WD LOCK can be done with the vehicle stopped or in motion. With the vehicle in motion, the transfer case will engage / disengage faster if you momentarily release the accelerator pedal after mov- ing the 4WD Control Switch. If the vehicle is stopped, the ignition switch must be in the ON position with the engine either OFF or RUNNING. This shift cannot be completed if the ignition switch is in the ACC position. NOTE: † The 4-wheel drive system will not allow shifts be- tween 2WD and 4WD LOCK if the rear wheels are spinning (no traction). In this situation, the selected position indicator light will flash and the original position indicator light will remain ON. At this time,

reduce speed and stop spinning the wheels to com- plete the shift. There may be a delay up to 10 seconds for the shift to complete after the wheels have stopped spinning. † Delayed shifting out of 4WD LOCK may be experi- enced due to uneven tire wear, low tire pressure, or excessive loading.

4WD Lock to 4WD Low When shifting into or out of 4WD LOW, some gear noise may be heard. This noise is normal and is not detrimental to the vehicle or its occupants Shifting can be performed with the vehicle rolling 2-3
mph (3-5 km/h) using the “Preferred Procedure” or completely stopped using the “Alternate Procedure.”

Preferred Procedure 1. With the engine RUNNING, slow the vehicle speed to 2-3 mph (3-5 km/h). 2. Shift the transmission into “N” (Neutral) (automatic transmission), or depress the clutch pedal (manual trans- mission). 3. While still rolling, move the 4WD Control Switch to the desired position. 4. After the desired position indicator light is ON (not flashing), shift the transmission into gear (automatic transmission), or release the clutch pedal (manual trans- mission). Alternate Procedure 1. Bring the vehicle to a complete stop.

STARTING AND OPERATING 297

2. With the ignition switch in the ON position, and the engine OFF or RUNNING, shift the transmission into “N” (Neutral) (automatic transmission), or depress the clutch pedal (manual transmission). 3. Move the 4WD Control Switch to the desired position. 4. After the desired position indicator light is ON (not flashing), shift the transmission into gear (automatic transmission), or release the clutch pedal (manual trans- mission). NOTE: † Steps 1 and 2 in the “Preferred Procedure” and the “Alternate Procedure” are requirements for shifting the transfer case. If these requirements are not met prior to attempting the shift or while the shift attempt is in process, then the indicator light will flash, and the current transfer case position will be maintained. To retry a shift, move the 4WD Control Switch back to the

original position, make certain all shift requirements have been met, wait five (5) seconds, and try the shift again. † The ignition switch must be in the ON position for a shift to take place and for the position indicator lights to be operable. If the ignition switch is not in the ON position, then the shift will not take place and no position indicator lights will be on or flashing.

MP3022 Selec-Trac IIT Transfer Case — If Equipped

Operating Information & Precautions The Selec-Trac IIt active on-demand transfer case pro- vides four positions: † 2 (rear) wheel drive high range. † 4-wheel drive auto high range.

† Neutral. † 4-wheel drive low range. This transfer case is intended to be driven in either the 2-wheel drive position (2WD) or the 4-wheel drive Auto position (4WD Auto) for normal street and highway conditions such as dry hard surfaced roads. For added capability when traversing steep grades, rough terrain, or extremely poor traction surfaces, select the transfer case 4WD Low position. This position locks the front driveshaft and rear driveshaft together and forces the front and rear wheels to rotate at the same speed while multiplying engine torque. Use the transfer case Neutral (N) position for recreational towing only. Refer to “Recreational Towing” in this section for specific procedures on shifting into and out of Neutral (N).

CAUTION!

† The 4WD Low position is intended for loose or slippery road surfaces only. Driving in this posi- tion on dry hard surfaced roads may cause in- creased tire wear and damage to the driveline components. † When operating your vehicle in 4WD LOW, the engine speed is approximately three times that of the 2WD position or 4WD AUTO position at a given road speed. Take care not to over-speed the engine and do not exceed 25 mph (40 km/h). † Proper operation of 4-wheel drive vehicles de- pends on tires of equal size, type, and circumfer- ence on each wheel. Any difference in tire size can cause damage to the transfer case.

ON-ROAD DRIVING TIPS Utility vehicles have higher ground clearance and a narrower track to make them capable of performing in a wide variety of off-road applications. Specific design characteristics give them a higher center of gravity than ordinary cars. An advantage of the higher ground clearance is a better view of the road, allowing you to anticipate problems. They are not designed for cornering at the same speeds as

304 STARTING AND OPERATING

conventional 2-wheel drive vehicles any more than low- slung sports cars are designed to perform satisfactorily in off-road conditions. If at all possible, avoid sharp turns or abrupt maneuvers. As with other vehicles of this type, failure to operate this vehicle correctly may result in loss of control or vehicle rollover.

OFF-ROAD DRIVING TIPS

When To Use 4WD Low Range When off-road driving, shift to 4WD Low for additional traction and control on slippery or difficult terrain, ascending or descending steep hills, and to increase low-speed pulling power. This range should be limited to extreme situations such as deep snow, mud, or sand where additional low speed pulling power is needed. Vehicle speeds in excess of 25 mph (40 km/h) should be avoided when in 4WD Low range.

Driving Through Water Although your vehicle is capable of driving through water, there are a number of precautions that must be considered before entering the water:

CAUTION!

When driving through water, do not exceed 5 mph (8
km/h). Always check water depth before entering as a precaution, and check all fluids afterward. Driving through water may cause damage that may not be covered by the new vehicle limited warranty.

Driving through water more than a few inches deep will require extra caution to ensure safety and prevent dam- age to your vehicle. If you must drive through water, try to determine the depth and the bottom condition (and location of any obstacles) prior to entering. Proceed with

caution and maintain a steady controlled speed less than 5 mph (8 km/h) in deep water to minimize wave effects. Flowing Water If the water is swift flowing and rising (as in storm run-off) avoid crossing until the water level recedes and/or the flow rate is reduced. If you must cross flowing-water, avoid depths in excess of 9 inches. The flowing water can erode the streambed causing your vehicle to sink into deeper water. Determine exit point(s) that are downstream of your entry point to allow for drifting. Standing Water Avoid driving in standing water deeper than 20 inches, and reduce speed appropriately to minimize wave ef- fects. Maximum speed in 20 inches of water is less than 5
mph (8 km/h).

STARTING AND OPERATING 305

Maintenance After driving through deep water, inspect your vehicle fluids and lubricants (engine, transmission, axle, transfer case) to assure they have not been contaminated. Con- taminated fluids and lubricants (milky, foamy in appear- ance) should be flushed/changed as soon as possible to prevent component damage. Driving In Snow, Mud and Sand In heavy snow, when pulling a load, or for additional control at slower speeds, shift the transmission to a low gear and shift the transfer case to 4WD Low if necessary. Refer to “Four-Wheel Drive Operation” in this section. Do not shift to a lower gear than necessary to maintain headway. Over-revving the engine can spin the wheels and traction will be lost. Avoid abrupt downshifts on icy or slippery roads, be- cause engine braking may cause skidding and loss of control.

306 STARTING AND OPERATING

Hill Climbing

NOTE: Before attempting to climb a hill, determine the conditions at the crest and/or on the other side. Before climbing a steep hill, shift the transmission to a lower gear and shift the transfer case to 4WD Low. Use first gear and 4WD Low for very steep hills. If you stall or begin to lose headway while climbing a steep hill, allow your vehicle to come to a stop and immediately apply the brakes. Restart the engine and shift to R (Reverse). Back slowly down the hill allowing the compression braking of the engine to help regulate your speed. If the brakes are required to control vehicle speed, apply them lightly and avoid locking or skidding the tires.

WARNING!

If the engine stalls or you lose headway or cannot make it to the top of a steep hill or grade, never attempt to turn around. To do so may result in tipping and rolling the vehicle. Always back straight down a hill in R (Reverse) gear carefully. Never back down a hill in N (Neutral) using only the brake.

Remember, never drive diagonally across a hill-always drive straight up or down. If the wheels start to slip as you approach the crest of a hill, ease off the accelerator and maintain headway by turning the front wheels slowly left and right. This may provide a fresh “bite” into the surface and will usually provide traction to complete the climb.

Traction Downhill Shift the transmission into a low gear and the transfer case to 4WD Low range. Let the vehicle go slowly down the hill with all four wheels turning against engine compression drag. This will permit you to control the vehicle speed and direction. When descending mountains or hills, repeated braking can cause brake fade with loss of braking control. Avoid repeated heavy braking by downshifting the transmis- sion whenever possible. After Driving Off-Road Off-road operation puts more stress on your vehicle than does most on-road driving. After going off-road, it is always a good idea to check for damage. That way you can get any problems taken care of right away and have your vehicle ready when you need it.

STARTING AND OPERATING 307

† Completely inspect the underbody of your vehicle. Check tires, body structure, steering, suspension, and exhaust system for damage. † Check threaded fasteners for looseness, particularly on the chassis, drivetrain components, steering, and sus- pension. Retighten them, if required, and torque to the values specified in the Service Manual. † Check for accumulations of plants or brush. These things could be a fire hazard. They might hide damage lines, brake hoses, axle pinion seals, and to fuel propeller shafts. † After extended operation in mud, sand, water, or similar dirty conditions, have brake rotors, wheels, brake linings, and axle yokes inspected and cleaned as soon as possible.

308 STARTING AND OPERATING

WARNING!

Abrasive material in any part of the brakes may cause excessive wear or unpredictable braking. You might not have full braking power when you need it to prevent an accident. If you have been operating your vehicle in dirty conditions, get your brakes checked and cleaned as necessary.

† If you experience unusual vibration after driving in mud, slush, or similar conditions, check the wheels for impacted material. Impacted material can cause a wheel imbalance and freeing the wheels of it will correct the situation.

PARKING BRAKE To set the parking brake, pull the lever up as firmly as possible. When the parking brake is applied with the ignition ON, the “Brake Warning Light” in the instru- ment cluster will light. To release the parking brake, pull up slightly, press the center button, then lower the lever completely. NOTE: The instrument cluster “Brake Warning Light” indicates only that the parking brake is applied. You must be sure the parking brake is fully applied before leaving the vehicle.

STARTING AND OPERATING 309

Be sure the parking brake is firmly set when parked, and the gear selector lever is in the “P” (Park) position (automatic transmission) or “R” (Reverse) or 1st gear (manual transmission). When parking on a hill, you should apply the parking brake before placing the gear selector lever in “P” (Park); otherwise, the load on the transmission locking mechanism may make it difficult to move the selector out of “P” (Park).

Parking Brake

310 STARTING AND OPERATING

WARNING!

† Always apply the parking brake fully when leav- ing your vehicle or it may roll and cause damage or injury. Also, be certain to leave an automatic transmission in “P” (Park) or a manual transmis- sion in “R” (Reverse) or 1st gear. Failure to do so may allow the vehicle to roll and cause damage or injury. † Leaving children in a vehicle unattended is dan- gerous for a number of reasons. A child or others could be injured. Don’t leave the keys in the ignition. A child could operate power windows, other controls, or move the vehicle. † Be sure the parking brake is fully disengaged before driving, failure to do so can lead to brake problems due to excessive heating of the rear brakes.

When parking on a hill, turn the front wheels toward the curb on a downhill grade and away from the curb on an uphill grade. The parking brake should always be applied whenever the driver is not in the vehicle.

ANTI-LOCK BRAKE SYSTEM The Anti-Lock Brake System (ABS) is designed to aid the driver in maintaining vehicle control under adverse braking conditions. The system operates with a separate computer to modulate hydraulic pressure to prevent wheel lock-up and help avoid skidding on slippery surfaces. All vehicle wheels and tires must be the same size and type and tires must be properly inflated to produce accurate signals for the computer.

WARNING!

WARNING!

STARTING AND OPERATING 311

Significant over or under inflation of tires or mixing sizes of tires or wheels on the vehicle can lead to loss of braking effectiveness.

The Anti-Lock Brake System conducts a low-speed self- test at about 12 mph (20 km/h). If you have your foot lightly on the brake while this test is occurring, you may feel slight pedal movement. The movement can be more apparent on ice and snow. This is normal. The Anti-Lock Brake System pump motor runs during the self-test at 12 mph (20 km/h) and during an ABS stop. The pump motor makes a low humming noise during operation, which is normal.

Pumping of the Anti-Lock Brakes will diminish their effectiveness and may lead to an accident. Pumping makes the stopping distance longer. Just press firmly on your brake pedal when you need to slow down or stop.

312 STARTING AND OPERATING

WARNING!

CAUTION!

† The Anti-Lock Brake System (ABS) cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking or steering efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction afforded.

† The ABS cannot prevent accidents,

including those resulting from excessive speed in turns, following another vehicle too closely, or hydro- planing. Only a safe, attentive, and skillful driver can prevent accidents. † The capabilities of an ABS equipped vehicle must never be exploited in a reckless or dangerous manner, which could jeopardize the user’s safety or the safety of others.

The Anti-Lock Brake System is subject to possible detrimental effects of electronic interference caused by improperly installed after-market radios or telephones.

NOTE: During severe braking conditions, a pulsing sensation may occur and a clicking noise will be heard. This is normal, the Anti-Lock Brake System is functioning.

indicating that

WARNING!

To use your brakes and accelerator more safely, follow these tips:

† Do not “ride” the brakes by resting your foot on the pedal. This could overheat the brakes and result in longer stopping dis- unpredictable braking action, tances, or brake damage. † When descending mountains or hills, repeated brak- ing can cause brake fade with loss of braking control. Avoid repeated heavy braking by downshifting the transmission or locking out overdrive whenever pos- sible. † Engines may idle at higher speeds during warm-up, which could cause rear wheels to spin and result in loss of vehicle control. Be especially careful while driving on slippery roads, in close quarter maneuver- ing, parking, or stopping. † Do not drive too fast for road conditions, especially when roads are wet or slushy. A wedge of water can

STARTING AND OPERATING 313

build up between the tire tread and the road. This hydroplaning action can cause loss of traction, braking ability, and control. † After going through deep water or a car wash, brakes may become wet, resulting in decreased performance and unpredictable braking action. Dry the brakes by gentle, intermittent pedal action while driving at very slow speeds.

POWER STEERING The standard power steering system will give you good vehicle response and increased ease of maneuverability in tight spaces. The system will provide mechanical steering capability if power assist is lost. If for some reason the power assist is interrupted, it will still be possible to steer your vehicle. Under these condi- tions, you will observe a substantial increase in steering effort, especially at very low vehicle speeds and during parking maneuvers.

314 STARTING AND OPERATING

Increased noise levels at the end of the steering NOTE: wheel travel are considered normal and do not indicate that there is a problem with the power steering system. Upon initial start-up in cold weather, the power steering pump may make noise for a short amount of time. This is due to the cold, thick fluid in the steering system. This noise should be considered normal, and it does not in any way damage the steering system.

WARNING!

Continued operation with reduced power steering assist could pose a safety risk to yourself and others. Service should be obtained as soon as possible.

CAUTION!

Prolonged operation of the steering system at the end of the steering wheel travel will increase the steering fluid temperature and it should be avoided when possible. Damage to the power steering pump may occur.

ELECTRONIC BRAKE CONTROL SYSTEM Your vehicle is equipped with an advanced electronic brake control system commonly referred to as ESP. This system includes ABS (Anti-Lock Brake System), TCS (Traction Control System), BAS (Brake Assist System), HSA (Hill Start Assist), ERM (Electronic Roll Mitigation), and ESP (Electronic Stability Program). These systems work together to enhance both vehicle stability and control in various driving conditions.

Two additional electronic brake control system options are HDC (Hill Descent Control) and TSC (Trailer Sway Control). Your vehicle may be equipped with one or both of these options. ABS (Anti-Lock Brake System)

This system aids the driver in maintaining vehicle control under adverse braking conditions. The system controls hydraulic brake pressure to prevent wheel lock-up to help avoid skidding on slippery surfaces during braking. Refer to “Anti-Lock Brake System” in Section 5 of this manual for more information about ABS.

STARTING AND OPERATING 315

WARNING!

ABS (Anti-Lock Brake System) cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded by prevailing road conditions. ABS cannot prevent accidents, in- cluding those resulting from excessive speed in turns, driving on very slippery surfaces, or hydro- planing. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ABS- equipped vehicle must never be exploited in a reck- less or dangerous manner, which could jeopardize the user’s safety or the safety of others.

316 STARTING AND OPERATING

TCS (Traction Control System)

This system monitors the amount of wheel spin of each of the driven wheels. If wheel spin is detected, brake pressure is applied to the slipping wheel(s) and engine power is reduced to provide enhanced acceleration and stability. A feature of the TCS system functions similar to a limited slip differential and controls the wheel spin across a driven axle. If one wheel on a driven axle is spinning faster than the other, the system will apply the brake of the spinning wheel. This will allow more engine torque to be applied to the wheel that is not spinning. This feature remains active even if TCS and ESP are in the “Partial Off” mode or the “Full Off” mode. Refer to “ESP (Electronic Stability Program)” in this section for more information.

BAS (Brake Assist System) The BAS is designed to optimize the vehicle’s braking capability during emergency braking maneuvers. The system detects an emergency braking situation by sens- ing the rate and amount of brake application and then applies optimum pressure to the brakes. This can help reduce braking distances. The BAS complements the anti-lock brake system (ABS). Applying the brakes very quickly results in the best BAS assistance. To receive the benefit of the system, you must apply continuous brak- ing pressure during the stopping sequence, (do not “pump” the brakes). Do not reduce brake pedal pressure unless braking is no longer desired. Once the brake pedal is released, the BAS is deactivated.

WARNING!

BAS (Brake Assist System) cannot prevent the natu- ral laws of physics from acting on the vehicle, nor can it increase the traction afforded by prevailing road conditions. BAS cannot prevent accidents, including those resulting from excessive speed in turns, driving on very slippery surfaces, or hydroplaning.

lift,

ERM (Electronic Roll Mitigation) This system anticipates the potential for wheel lift by monitoring the driver’s steering wheel input and the speed of the vehicle. When ERM determines that the rate of change of the steering wheel angle and vehicle’s speed are sufficient to potentially cause wheel it then applies the appropriate brake and may also reduce engine power to lessen the chance that wheel lift will occur. ERM will only intervene during very severe or evasive driving maneuvers. ERM can only reduce the chance of wheel lift occurring during severe or evasive driving maneuvers. It cannot prevent wheel lift due to other factors, such as road conditions, leaving the road- way, or striking objects or other vehicles. NOTE: ERM is disabled anytime the ESP is in “Full Off” mode. Refer to ESP (Electronic Stability Program) for a complete explanation of the available ESP modes.

318 STARTING AND OPERATING

WARNING!

Many factors, such as vehicle loading, road condi- tions, and driving conditions, influence the chance that wheel lift or rollover may occur. ERM (Electronic Roll Mitigation) cannot prevent all wheel lift or rollovers, especially those that involve leaving the roadway or striking objects or other vehicles. Only a safe, attentive, and skillful driver can prevent acci- dents. The capabilities of an ERM-equipped vehicle must never be exploited in a reckless or dangerous manner, which could jeopardize the user’s safety or the safety of others.

TSC (Trailer Sway Control) – If Equipped TSC uses sensors in the vehicle to recognize an exces- sively swaying trailer. TSC activates automatically once the excessively swaying trailer is recognized. When TSC is functioning, the “ESP/TCS Indicator” light will flash, the engine power will be reduced, and you will feel the brake being applied to individual wheels in an attempt to stop the trailer from swaying. NOTE: The TSC is disabled when the ESP system is in the “Partial Off” mode and “Full Off” mode.

WARNING!

† TSC (Trailer Sway Control) cannot stop all trailers from swaying. Always use caution when towing a trailer and follow the tongue weight recommenda- tions. Refer to ”Vehicle Loading” and “Trailer Towing” in this section for more information be- fore towing a trailer with your vehicle. † If TSC activates while towing a trailer, stop the vehicle at the nearest safe location and adjust the trailer load to eliminate the trailer sway. † Failure to follow these warnings can result in an

accident or serious personal injury.

STARTING AND OPERATING 319

HSA (Hill Start Assist) The HSA system is designed to help the driver accelerate the vehicle from a complete stop while on an incline. If the driver releases the brake while stopped on an incline, HSA will continue to hold the brake pressure for a short period. If the driver does not apply the throttle before this time expires, the system will release brake pressure and the vehicle will roll down the hill as normal. The system will release brake pressure in proportion to amount of throttle applied. The following conditions must be met in order for HSA to activate: † The vehicle must be stopped. † The vehicle must be on a 7% or greater incline. † The Gear selection must match vehicle uphill direction (i.e. vehicle facing uphill is in forward gear; vehicle backing uphill is in reverse gear).

320 STARTING AND OPERATING

† For vehicles equipped with an automatic transmission, the HSA will work in reverse gear and all forward gears. The system will not activate if the transmission is in “P” (Park). † For vehicles equipped with a manual transmission, the HSA will work in reverse gear, neutral, and all forward gears.

WARNING!

There may be situations where the HSA (Hill Start Assist) will not activate and slight rolling may occur, such as on minor hills (i.e., less than 7%), or with a loaded vehicle, or while pulling a trailer. HSA is not a substitute for active driving involvement. It is always the driver’s responsibility to be attentive to distance to other vehicles, people, and objects, and most importantly brake operation to ensure safe operation of the vehicle under all road conditions. Your complete attention is always required while driving to maintain safe control of your vehicle. Failure to follow these warnings can result in an accident or serious personal injury.

Towing with HSA HSA will provide assistance during acceleration on an incline while towing a trailer.

WARNING!

† If you use a trailer brake controller with your trailer, the trailer brakes may be activated and deactivated with the brake switch. If so, there may not be enough brake pressure to hold both the vehicle and the trailer on a hill when the brake pedal is released. In order to avoid rolling down an incline while resuming acceleration, manually activate the trailer brake or apply more vehicle brake pressure prior to releasing the brake pedal. † HSA is not a parking brake. Always apply the parking brake fully when leaving your vehicle. Also, be certain to leave an automatic transmission in “P” (Park) or a manual transmission in “R” (Reverse) or 1st gear. † Failure to follow these warnings can result in an

accident or serious personal injury.

If the sequence was completed properly, the “ESP/TCS Indicator” light will blink sev- eral times to confirm HSA is disabled. 10. Repeat these steps if you want to return this feature to its previous setting.

HDC (Hill Descent Control) – If Equipped HDC is only intended for low speed off-road driving. HDC maintains vehicle speed while descending hills in off-road driving conditions by applying the brakes when necessary. When enabled, HDC senses the terrain and activates when the vehicle is descending a hill. HDC speed may be adjusted by the driver to suit the driving conditions. The speed corresponds to the transmission gear selected. Gear 1st 2nd D (Drive) R (Reverse) N (Neutral) However, the driver can override HDC operation by applying the brake to slow the vehicle down below the

ESP (Electronic Stability Program) This system enhances directional control and stability of the vehicle under various driving conditions. ESP cor- rects for oversteering and understeering the vehicle by applying the brake of the appropriate wheel. Engine power may also be reduced to help the vehicle maintain the desired path.

The ESP uses sensors in the vehicle to determine the path that the driver intends to steer the vehicle and compares it to the actual path of the vehicle. When the actual path does not match the intended path, the ESP applies the brake of the appropriate wheel to assist in counteracting the condition of oversteer or understeer. † Oversteer - when the vehicle is turning more than † Understeer - when the vehicle is turning less than

ESP/TCS Indicator Light

The 9ESP/TCS Indicator” light located in the instrument cluster, starts to flash as soon as the tires lose traction and the ESP system becomes active. The 9ESP/TCS Indicator” light also flashes when TCS is active. If the 9ESP/TCS Indicator” light begins to flash during acceleration, 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.

WARNING!

ESP (Electronic Stability Program) cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded by prevailing road conditions. ESP cannot prevent accidents, in- cluding those resulting from excessive speed in turns, driving on very slippery surfaces, or hydro- planing. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ESP- equipped vehicle must never be exploited in a reck- less or dangerous manner, which could jeopardize the user’s safety or the safety of others.

STARTING AND OPERATING 325

Depending upon model and mode of operation, the ESP system has up to three operating modes: “ESP On” “Partial Off,” and “Full Off.” ESP On — 2WD Vehicles & 4WD Vehicles in 2WD & 4WD High Range This is the normal operating mode for ESP when operat- ing a 2WD vehicle. It is also the normal mode for operating a 4WD vehicle in 2WD or 4WD high range. The ESP system will be in “ESP On” mode whenever the vehicle is started or the transfer case (if equipped) is shifted out of 4WD low range. This mode should be used for most driving situations. ESP should only be turned to “Partial Off” or “Full Off” for specific reasons as noted. Refer to “Partial Off” and to “Full Off” for additional information.

326 STARTING AND OPERATING

Partial Off — 2WD Vehicles & 4WD Vehicles in 2WD & 4WD High Range The “Partial Off” mode is intended for driving in deep snow, sand, or gravel. This mode raises the threshold for TCS and ESP activation, which allows for more wheel spin than what ESP normally allows. The “ESP OFF” button is located in the lower switch bank below the climate Control. To enter the “Partial Off” mode, momentarily depress the “ESP OFF” button and the 9ESP/TCS Indicator” light will illuminate. To turn the ESP on again, momentarily depress the 9ESP OFF9 button and the 9ESP/TCS Indicator” light will turn off. This will restore the normal “ESP On” mode of operation.

ESP Off Button

NOTE: To improve the vehicle’s traction when driving with snow chains, or when starting off in deep snow, sand, or gravel, it may be desirable to switch to the “Partial Off” mode by momentarily depressing the “ESP OFF” button. Once the situation requiring “Partial Off”

mode is overcome, turn ESP back on by momentarily depressing the “ESP OFF” button. This may be done while the vehicle is in motion. Full Off — 4WD Vehicles in 4WD High & 4WD Low Range The “Full Off” mode is intended for off-highway and off-road use when ESP stability features could inhibit vehicle maneuverability due to trail conditions. The “ESP OFF” button is located in the lower switch bank below the climate Control. To enter “Full Off” mode, depress and hold the “ESP Off” button for 5 seconds while the vehicle is stopped with the engine running. After 5 seconds, the “ESP/TCS Indicator” light will illuminate and an “ESP Off” message will appear in the odometer. Press and release the trip odometer button located on the instrument cluster to turn off this message. In this mode, ESP and TCS are turned off (except for the “limited slip” feature described in the TCS section) until

STARTING AND OPERATING 327

the vehicle reaches a speed of 40 mph. At speeds over 40
mph, the system automatically switches to “Partial Off” mode, described above. When the vehicle speed returns to less than 35 mph, the ESP system will return to “Full Off” mode. The “ESP/TCS Indicator” light is always illuminated when ESP is off. To turn ESP on again, momentarily depress the “ESP Off” button. This will restore the normal “ESP On” mode of operation. NOTE: † “Full Off” is the only operating mode for ESP in 4WD low range. Therefore, ESP system will be in this mode whenever the vehicle is started in 4WD low range or the transfer case is shifted into 4WD low range. † The “ESP OFF” message will display and a chime will sound when the gear selector is moved from any position to the “P” (Park) position and then moved out of the “P” (Park) position. This will occur even if the message was cleared previously.

328 STARTING AND OPERATING

WARNING!

With the ESP switched off, the enhanced vehicle stability offered by ESP is unavailable. In an emer- gency evasive maneuver, the ESP system will not engage to assist in maintaining stability. “Full Off” mode is only intended for off-highway or off-road use.

ESP/BAS Warning Light & ESP/TCS Indicator Light

The malfunction indicator for the ESP is com- bined with the BAS indicator. The “ESP/BAS Malfunction Indicator” light and the “ESP/ TCS Indicator” light in the instrument cluster both turn on when the ignition switch is turned to the ON position. They should both turn off with the engine running. If the “ESP/BAS Malfunction Indicator” light

turns on continuously with the engine running, a mal- function has been detected in either the ESP or the BAS system, or both. If this light remains on after several ignition cycles, and the vehicle has been driven several miles at speeds greater than 30 mph (48 km/h), see your authorized dealer as soon as possible to have the problem diagnosed and corrected. NOTE: † 9The 9ESP/TCS Indicator” light and the 9ESP/BAS Malfunction Indicator” light will turn on momentarily each time the ignition switch is turned ON. † Each time the ignition is turned ON, the ESP System † The ESP Control System will make buzzing or clicking sounds when it is active.

Tire and Loading Information Placard

STARTING AND OPERATING 333

Tire Placard Location NOTE: The proper cold tire inflation pressure is listed on either the face of the driver’s door or the driver’s side “B” pillar.

Tire and Loading Information

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

Tire Placard Location

334 STARTING AND OPERATING

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” sec- tion of this manual. NOTE: Under a maximum loaded vehicle condition, gross axle weight ratings (GAWR’s) for the front and rear axles must not be exceeded. For further information on GAWR’s, vehicle loading, and trailer towing, refer to the “Vehicle Loading” section of this manual. To determine the maximum loading conditions of your vehicle, locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” 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 pounds” 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 kilograms or XXX pounds. 4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if “XXX” amount equals 1400 lbs. and there will be five 150 lb. passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (since 5 x 150 = 750, and 1400 – 750 = 650 lbs.)

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.

kg).

336 STARTING AND OPERATING

WARNING!

1. Safety—

STARTING AND OPERATING 337

Overloading of your tires is dangerous. Overloading can cause tire failure, affect vehicle handling, and increase your stopping distance. Use tires of the recommended load capacity for your vehicle. Never overload them.

TIRES — GENERAL INFORMATION

Tire Pressure Proper tire inflation pressure is essential to the safe and satisfactory operation of your vehicle. Three primary areas are affected by improper tire pressure:

WARNING!

† Improperly inflated tires are dangerous and can cause accidents. † Under inflation increases tire flexing and can result in 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. † Unequal tire pressures can cause steering problems. You could lose control of your vehicle. † Over inflated or under inflated tires can affect vehicle handling and can fail suddenly, resulting in loss of vehicle control. † 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 recommended cold tire inflation pressure.

338 STARTING AND OPERATING

2. Economy— Improper inflation pressures can cause uneven wear patterns to develop across the tire tread. These abnormal wear patterns will reduce tread life resulting in a need for earlier tire replacement. Under inflation also increases tire rolling resistance and results in higher fuel consump- tion. 3. Ride Comfort and Vehicle Stability— Proper tire inflation contributes to a comfortable ride. Over inflation produces a jarring and uncomfortable ride. Both under inflation and over inflation affect the stability of the vehicle and can produce a feeling of sluggish response or over responsiveness in the steering. Unequal tire pressures can cause erratic and unpredict- able steering response. Unequal tire pressure from side to side may cause the vehicle to drift left or right.

Tire Inflation Pressures The proper cold tire inflation pressure is listed on either the face of the driver’s door or the driver’s side “B” pillar.

Tire Placard Location

The pressure should be checked and adjusted as well as inspecting 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 (if equipped). 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 3 hours, or driven less than 1 mile (1 km) after a 3 hour period. The cold tire inflation pressure must not exceed the maximum inflation pres- sure molded into the tire sidewall.

STARTING AND OPERATING 339

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.

340 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. Don’t 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 dealer for radial tire repairs. Tire Spinning When stuck in mud, sand, snow, or ice conditions, do not spin your vehicle’s wheels above 35 mph (55 km/h).

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 35
mph (55 km/h) when you are stuck, and do not let anyone near a spinning wheel no matter what the speed.

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

STARTING AND OPERATING 341

These indicators are molded into the bottom of the tread grooves. They will appear as bands when the tread depth becomes 1/16 inch (2 mm). When the indicators appear in 2 or more adjacent grooves, the tire should be replaced. Many states have laws requiring tire replacement at this point.

342 STARTING AND OPERATING

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

WARNING!

Tires and 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. 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 tire. The service description and load identification will be found on the original equipment tire. Failure to use equivalent replacement tires may adversely affect the safety, handling, and ride of your vehicle. We recommend that you contact your original equipment or an autho- rized tire dealer with any questions you may have on tire specifications or capability.

STARTING AND OPERATING 343

WARNING!

CAUTION!

† 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 suspension dimensions and performance characteristics, result- ing in changes to steering, handling, and braking of your vehicle. This can cause unpredictable handling and stress to steering and suspension 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, 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 an accident. † Failure to equip your vehicle with tires having ad- equate speed capability can result in sudden tire failure and loss of vehicle control.

Replacing original tires with tires of a different size may result in false speedometer and odometer readings.

Alignment and Balance Poor suspension alignment may result in: † Fast tire wear. † Uneven tire wear, such as feathering and one-sided † Vehicle pull to right or left. Tires may also cause the vehicle to pull left or right. Alignment will not correct this problem. See your autho- rized dealer for proper diagnosis.

wear.

344 STARTING AND OPERATING

Improper alignment will not cause vehicle vibration. Vibration may be a result of tire and wheel out-of- balance. Proper balancing will reduce vibration and avoid tire cupping and spotty wear.

TIRE CHAINS Use only compact chains, or other traction aids that meet SAE type “Class S” specifications. Chains must be the proper size for the vehicle, as recommended by the chain manufacturer. In addition, only install tire chains on P235/65R17 or smaller tires.

CAUTION!

To avoid damage to your vehicle, tires, or chains, observe the following precautions: † Do not use tire chains on vehicles equipped with tires other than P235/65R17 tires. There may not be adequate clearance for the chains and you are risking structural or body damage to your vehicle. † Because of limited chain clearance between tires and other suspension components, it is important that only chains in good condition are used. Broken chains can cause serious vehicle damage. Stop the vehicle immediately if noise occurs that could suggest chain breakage. Remove the damaged parts of the chain before further use. † Install chains on the rear wheels as tightly as possible and then retighten † Do not exceed 45 mph (72 km/h). † Drive cautiously and avoid severe turns and large bumps, especially with † Use on Rear Wheels only. † Do not drive for a prolonged period on dry pavement. † Observe the tire chain manufacturer’s instructions on method of instal- lation, operating speed, and conditions for use. Always use the lower suggested operating speed of the chain manufacturer if different from the speed recommended by the manufacturer.

after driving about 1⁄2 mile (0.8 km).

a loaded vehicle.

These cautions apply to all chain traction devices, includ- ing link and cable (radial) chains.

TIRE ROTATION RECOMMENDATIONS Tires on the front and rear axles of vehicles operate at different loads and perform different steering, handling, and braking functions. For these reasons, they wear at unequal rates, and develop irregular wear patterns. 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.

STARTING AND OPERATING 345

Follow the “Maintenance Schedule” in Section 8 of this manual for the recommended tire rotation frequency. Remember, more frequent rotation is permissible if de- sired. Also, correct for anything causing rapid or unusual wear prior to performing the tire rotation. The suggested rotation method is the “forward-cross” shown in the following diagram.

346 STARTING AND OPERATING

TIRE PRESSURE MONITOR SYSTEM (TPMS) — IF EQUIPPED † The Tire Pressure Monitor System (TPMS) will warn the driver of a low tire pressure based on the vehicle recommended cold placard pressure. † The tire pressure will vary with temperature by about 1 psi (6.9 kPa) for every 12°F (6.5°C). This means that when the outside temperature decreases, the tire pres- sure 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 3 hours, or driven less than 1 mile (1 km) after a 3 hour period. The cold tire inflation pressure must not exceed the maximum inflation pressure molded into the tire sidewall. Refer to the “Tires – General Information” in this section 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 TPM System will warn the driver of a low tire pressure if the tire pressure falls below the low- pressure warning limit for any reason, including low temperature effects and natural pressure loss through the tire. † The TPM System will continue to warn the driver of low tire pressure as long as the condition exists, and will not turn off until the tire pressure is at or above the recommended cold placard pressure. Once the low tire pressure warning (Tire Pressure Monitoring Tell- tale Light) illuminates, you must increase the tire pressure to the recommended cold placard pressure in order for the Tire Pressure Monitoring Telltale Light to turn off. The system will automatically update and the Tire Pressure Monitoring Telltale Light will turn off

once the system receives the updated tire pressures. The vehicle may need to be driven for up to 10 minutes above 15 mph (25 km/h) in order for the TPMS to receive this information. − For example, your vehicle may have a recom- mended cold (parked for more than 3 hours) placard pressure of 33 psi (227 kPa). If the ambient tempera- ture 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 are inflated to the vehicle’s recommended cold placard pressure value.

STARTING AND OPERATING 347

CAUTION!

† The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures and warning have been established for the tire size equipped on your vehicle. Undesirable system operation or sensor damage may result when us- ing replacement equipment that is not of the same size, type, and/or style. Aftermarket wheels can cause sensor damage. Do not use aftermarket tire sealants or balance beads if your vehicle is equipped with a TPMS, as damage to the sensors may result. † After inspecting or adjusting the tire pressure, always reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the Tire Pressure Moni- toring Sensor.

348 STARTING AND OPERATING

while adjusting your tire pressure.

NOTE: † The TPMS is not intended to replace normal tire care and maintenance, or to provide warning of a tire failure or condition. † The TPMS should not be used as a tire pressure gauge † Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. † The TPMS is not a substitute for proper tire mainte- nance, and it is the driver’s responsibility to maintain correct tire pressure using an accurate tire pressure gauge, even if under-inflation has not reached the level to trigger illumination of the Tire Pressure Moni- toring Telltale light.

† Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire.

Base System — If Equipped The Tire Pressure Monitor System (TPMS) uses wireless technology with wheel rim mounted electronic sensors to monitor tire pressure levels. Sensors, mounted to each wheel as part of the valve stem, transmit tire pressure readings to the Receiver Module. It is particularly important for you to check the NOTE: tire pressure in all of the tires on your vehicle monthly and to maintain the proper pressure. The TPMS consists of the following components: † Receiver Module † 4 Tire Pressure Monitoring Sensors † Tire Pressure Monitoring Telltale Light

The matching full size spare wheel and tire assembly (if equipped) has a tire pressure monitoring sensor. The matching full size spare can be used in place of any of the four road tires. The TPMS will only monitor the pressure in the full size spare when it is used in place of a road tire. Otherwise, a spare with a pressure below the low- pressure limit will not cause the Tire Pressure 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 a chime will sound when tire pressure is low in one or more of the four active road tires. Should this occur, you should stop as soon as possible, check the inflation pressure of each tire on your vehicle, and inflate each tire to the vehicle’s recommended cold placard pressure value. Once the system receives the updated tire pres- sures, the system will automatically update and the Tire Pressure Monitoring Telltale Light will turn off. The

vehicle may need to be driven for up to 10 minutes above 15 mph (25 km/h) in order for the TPMS to receive this information. Check TPMS Warning When a system fault is detected, the Tire Pressure Moni- toring Telltale Light will flash on and off for 75 seconds and then remain on solid. The system fault will also sound a chime. If the ignition key is cycled, this sequence will repeat, providing the system fault still exists. The Tire Pressure Monitoring Telltale Light will turn off when the fault condition no longer exists. A system fault can occur due to any of the following: 1. Jamming due to electronic devices or driving next to facilities emitting the same Radio Frequencies as the 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:

Vehicles with Full Size Spare 1. The matching full size spare wheel and tire assembly has a tire pressure monitoring sensor that can be moni- tored by the TPMS. 2. If you install the full size spare in place of a road tire that has a pressure below the low-pressure warning limit, upon the next ignition key cycle, a chime will sound and the TPM Telltale Light will turn ON. 3. Driving the vehicle for up to 10 minutes above 15 mph (25 km/h) will turn off the TPM Telltale Light, as long as no tire pressure is below the low-pressure warning limit in any of the four active road tires.

NOTE:

Vehicles with Compact Spare 1. The compact spare tire does not have a tire pressure monitoring sensor. Therefore, the TPMS will not monitor the pressure in the compact spare tire. 2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure warning limit, upon the next ignition key cycle, a chime will sound and the TPM Telltale Light will turn ON. 3. After driving the vehicle for up to 10 minutes above 15
mph (25 km/h), the TPM Telltale Light will flash on and off for 75 seconds and then remain on solid. 4. For each subsequent ignition key cycle, a chime will sound and the TPM Telltale Light will flash on and off for 75 seconds and then remain on solid. 5. Once you repair or replace the original road tire, and reinstall it on the vehicle in place of the compact spare, the TPMS will update automatically and the TPM 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 10

FUEL REQUIREMENTS

Your 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. Under normal conditions, the use of premium gasoline will not provide a benefit over high quality regular gasolines, and in some circumstances may result in poorer performance. Light spark knock at low engine speeds is not harmful to your engine. However, continued heavy spark knock at

356 STARTING AND OPERATING

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 gasoline that meets the WWFC speci- fications if they are available. Reformulated Gasoline Many areas of the country require the use of cleaner burning gasoline referred to as “Reformulated Gasoline.” Reformulated gasolines contain oxygenates, and are spe- cifically blended to reduce vehicle emissions and im- prove air quality.

The manufacturer supports the use of reformulated gaso- lines. Properly blended reformulated gasolines will pro- vide excellent performance and durability of engine and fuel system components. Gasoline/Oxygenate Blends Some fuel suppliers blend unleaded gasoline with oxy- genates such as 10% ethanol, MTBE, and ETBE. Oxygen- ates are required in some areas of the country during the winter months to reduce carbon monoxide emissions. Fuels blended with these oxygenates may be used in your vehicle.

CAUTION!

DO NOT use gasolines containing Methanol or E85
Ethanol. Use of these blends may result in starting and driveability problems and may damage critical fuel system components.

Problems that result from using methanol/gasoline or E85 Ethanol blends are not the responsibility of the manufacturer. While MTBE is an oxygenate made from Methanol, it does not have the negative effects of Metha- nol. MMT In Gasoline MMT is a manganese containing metallic additive that is blended into some gasoline to increase octane. Gasoline blended with MMT provides no performance advantage beyond gasoline of the same octane number without MMT. Gasoline blended with MMT reduces spark plug life and reduces emission system performance in some vehicles. The manufacturer recommends that gasoline without MMT be used in your vehicle. The MMT content of gasoline may not be indicated on the gasoline pump; therefore, you should ask your gasoline retailer whether his/her gasoline contains MMT. It is even more impor- tant to look for gasolines without MMT in Canada, because MMT can be used at levels higher than those

STARTING AND OPERATING 357

allowed in the United States. MMT is prohibited in Federal and California reformulated gasoline. Materials Added to Fuel All gasoline sold in the United States is required to contain effective detergent additives. Use of additional detergents or other additives is not needed under normal conditions and they would result in additional cost. Therefore, you should not have to add anything to the fuel. Fuel System Cautions

CAUTION!

Follow these guidelines to maintain your vehicle’s performance:

358 STARTING AND OPERATING

† The use of leaded gas is prohibited by Federal law. Using leaded gasoline can impair engine performance, and damage the emission control system. † An out-of-tune engine, or certain fuel or ignition malfunctions, can cause the catalytic converter to overheat. If you notice a pungent burning odor or some light smoke, your engine may be out of tune or malfunctioning and may require immediate service. Contact your 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 concentrations of methanol.
