Note:  For important information regarding the safe operation of this type of vehicle, see General Information in the Wheels and Tires chapter.
Note:  Do not use 4H or 4L mode on dry, hard surfaced roads. Doing so can produce excessive noise, increase tire wear and may damage drive components. 4H or 4L mode is only intended for consistently slippery or loose surfaces. Use of 4L mode on these surfaces may produce some noise (such as occasional clunks), but will not damage drive components.
Note:  If 4L is selected while your vehicle is moving above 3 mph (5 km/h), the 4WD system will not perform a shift. This is normal and should be no reason for concern. Refer to Shifting to or from 4L (4X4 Low) for proper operation.
Note:  You can switch on and switch off the electronic locking differential by pressing the center of the 4WD control.   See  Electronic Locking Differential
4WD Indicator Lights
Note:  When a 4X4 system fault is present, the system will typically remain in whichever 4X4 mode was selected prior to the fault condition occurring. It will not default to 4X2 in all circumstances. When this warning is displayed, have your vehicle serviced by an authorized dealer.

Using the 2-Speed Automatic 4WD System With Mechanical Lock
This system provides similar 4A capabilities as other 2-speed Torque-On-Demand™ (TOD™) systems but with mechanically locking 4H and 4L settings. In 4A mode, the system is interactive with the road, continually monitoring and adjusting power delivery to the front and rear wheels to optimize traction based on terrain mode selection.   See  Principle of Operation
Note:  The AdvanceTrac system has the ability to take over control of the transfer case clutch in 4A mode and disable it during driving maneuvers when necessary.
Note:  4WD mode availability is based on terrain mode selection.   See  Principle of Operation
Note:  The information display may show messages during 4WD operation.   See  Information Messages

2H (4X2)
For general on-road driving, this mode provides optimal smoothness and fuel economy at high speeds. Sends power to the rear wheels only.
Note:  2H may engage or disengage automatically based on terrain mode selection.   See  Principle of Operation
4A (4X4 AUTO)
Provides electronic controlled four-wheel drive with power delivered to the front and rear wheels, as required, for increased traction. The system continuously monitors road conditions, driver's input as well as other vehicle sensors and optimizes the system's behavior based on terrain mode selection.
Note:  4A may engage or disengage automatically based on terrain mode selection.   See  Principle of Operation
4H (4X4 HIGH)
Provides mechanically locked four-wheel drive power to both the front and rear wheels for use in off-road or winter conditions such as deep snow, sand or mud. This mode is not for use on dry pavement.
Note:  4H may engage or disengage automatically based on terrain mode selection.   See  Principle of Operation
4L (4X4 LOW)
Provides mechanically locked four-wheel drive power to both the front and rear wheels with additional gearing for increased torque multiplication. Intended only for off-road applications such as deep sand, steep grades, or pulling heavy objects. 4L (4X4 low) will not engage while your vehicle is moving above 3 mph (5 km/h); this is normal and should be no reason for concern. Refer to Shifting to or from 4L (4X4 low) for proper operation.
Note:  4L may engage or disengage automatically based on terrain mode selection.   See  Principle of Operation
Shifting between 4WD system modes
Note:  Momentarily releasing the accelerator pedal while a shift in progress message displays will improve engagement or disengagement performance.
Note:  Do not perform this operation if the rear wheels are slipping or when applying the accelerator pedal.
Note:  You may hear some noise as the system shifts or engages; this is normal.
You can move the control from 2H to 4A or 4H at a stop or while driving. The information display may display a message indicating a 4X4 shift is in progress and the LED light for the selected mode flashes. Once the shift is complete the information display shows the system mode selected and the LED light for the selected mode turns solid.
Shifting to or from 4L (4X4 low)
Note:  You may hear some noise as the system shifts or engages; this is normal.
  1. Bring your vehicle to a speed of 3 mph (5 km/h) or less.
  1. Place the transmission in neutral (N).
  1. Move the 4WD control to the desired position.
The information display will display a message indicating a 4X4 shift is in progress. The information display will then display the system mode selected. If any of the above shift conditions are not present, the shift will not occur and the information display will display information guiding the driver through the proper shifting procedures. If the above conditions are not satisfied in 30 seconds, the system reverts back to the previous 4WD mode or terrain mode.
If Shift Delayed Pull Forward displays in the information display, a transfer case gear tooth blockage is present. To alleviate this condition, place the transmission in a forward gear, move your vehicle forward approximately 5 ft (1.5 m), and shift the transmission back to neutral (N) to allow the transfer case to complete the range shift.
How Your Vehicle Differs From Other Vehicles
  WARNING:  Vehicles with a higher center of gravity (utility and four-wheel drive vehicles) handle differently than vehicles with a lower center of gravity (passenger cars). Avoid sharp turns, excessive speed and abrupt steering in these vehicles. Failure to drive cautiously increases the risk of losing control of your vehicle, vehicle rollover, personal injury and death.

Truck and utility vehicles can differ from some other vehicles. Your vehicle may be higher to allow it to travel over rough terrain without getting hung up or damaging underbody components.
The differences that make your vehicle so versatile also make it handle differently than an ordinary passenger car.
Maintain steering wheel control at all times, especially in rough terrain. Since sudden changes in terrain can result in abrupt steering wheel motion, make sure you grip the steering wheel from the outside. Do not grip the spokes.
Drive cautiously to avoid vehicle damage from concealed objects such as rocks and stumps.
You should either know the terrain or examine maps of the area before driving. Map out your route before driving in the area. To maintain steering and braking control of your vehicle, you must have all four wheels on the ground and they must be rolling, not sliding or spinning.
Driving Off-Road With Truck and Utility Vehicles
Note:  On some models, the initial shift from two-wheel drive to four-wheel drive while your vehicle is moving can cause some momentary clunk and ratcheting sounds. This is the front drivetrain coming up to speed and the automatic locking hubs engaging and is not cause for concern.
Note:  Momentarily releasing the accelerator pedal while a shift in progress message displays will improve engagement or disengagement performance.
Four-wheel drive vehicles are specially equipped for driving on sand, snow, mud and rough terrain and have operating characteristics that are somewhat different from conventional vehicles, both on and off the road.
The transfer case supplies power to all four wheels. On four-wheel drive vehicles, the transfer case allows you to select different 4WD modes when necessary. You can find information on transfer case operation and shifting procedures in this chapter. You can find information on transfer case maintenance in the Maintenance chapter. You should become thoroughly familiar with this information before you operate your vehicle.
Four-wheel drive (when you select a 4WD mode) uses all four wheels to power your vehicle. This increases traction, enabling you to drive over terrain and road conditions that a conventional two-wheel drive vehicle cannot.
Basic Operating Principles
  • Drive slower in strong crosswinds which can affect the normal steering characteristics of your vehicle.
  • When driving your vehicle on surfaces made slippery by loose sand, water, gravel, snow or ice proceed with care.
  • Do not use 4H or 4L on dry, hard surfaced roads. Doing so will produce excessive noise, increase tire wear and may damage drive components. 4H or 4L modes are only for consistently slippery or loose surfaces.
If Your Vehicle leaves the Road
If your vehicle leaves the road, reduce your vehicle speed and avoid severe braking. When your vehicle speed decreases, ease your vehicle back onto the road. Do not turn the steering wheel sharply while returning your vehicle to the road.
It may be safer to stay on the shoulder of the road and slow down gradually before returning to the road. You may lose control if you do not slow down or if you turn the steering wheel too sharply or abruptly.
It may be less risky to strike small objects, such as freeway reflectors, with minor damage to your vehicle rather than attempt a sudden return to the road which could cause your vehicle to slide sideways out of control or roll over. Remember, your safety and the safety of others should be your primary concern.
Emergency Maneuvers
In an unavoidable emergency situation where a sudden sharp turn must be made, remember to avoid over-driving your vehicle (i.e. turn the steering wheel only as rapidly and as far as required to avoid the emergency). Excessive steering can result in loss of vehicle control. Apply smooth pressure to the accelerator pedal or brake pedal when changes in vehicle speed are required. Avoid abrupt steering, acceleration and braking. This could result in an increased risk of vehicle roll over, loss of vehicle control and personal injury. Use all available road surface to bring your vehicle to a safe direction of travel.
In the event of an emergency stop, avoid skidding the tires and do not attempt any sharp steering wheel movements.
If your vehicle goes from one type of surface to another (i.e. from concrete to gravel) there will be a change in the way your vehicle responds to a maneuver (i.e. steering, acceleration or braking).
Sand
When driving over sand, try to keep all four wheels on the most solid area of the trail. Avoid reducing the tire pressures but shift to a lower gear and drive steadily through the terrain. Apply the accelerator slowly and avoid excessive wheel slip.
When driving at slow speeds in deep sand under high outside temperatures, use a low gear when possible. Low gear operation will maximize the engine and transmission cooling capability.
Avoid driving at excessive speeds, this causes vehicle momentum to work against you and your vehicle could become stuck to the point that assistance may be required from another vehicle. Remember, you may be able to back out the way you came if you proceed with caution.
Mud and Water
Mud
Be cautious of sudden changes in vehicle speed or direction when you are driving in mud. Even four-wheel drive vehicles can lose traction in slick mud. If your vehicle does slide, steer in the direction of the slide until you regain control of your vehicle.
After driving through mud, clean off residue stuck to rotating driveshafts and tires. Excess mud stuck on tires and rotating driveshafts can cause an imbalance that could damage drive components.
Water
If you must drive through high water, drive slowly. Traction or brake capability may be limited.
When driving through water, determine the depth to make sure your vehicle can safely travel through it.   See  Off-Road Driving.  If the ignition system gets wet, your vehicle may stall.
Once through water, always try the brakes. Wet brakes do not stop your vehicle as effectively as dry brakes. Drying improves by applying light pressure to the brake pedal while moving slowly.
Note:  Driving through deep water may damage the transmission. If the front or rear axle is submerged in water, the axle lubricant and power transfer unit lubricant should be checked and changed if necessary.
Driving on Hilly or Sloping Terrain
Although natural obstacles may make it necessary to travel diagonally up or down a hill or steep incline, you should always try to drive straight up or straight down.
Note:  Avoid turning on steep slopes or hills.A danger lies in losing traction, slipping sideways and possible vehicle roll over.Whenever driving on a hill, determine beforehand the route you will use.Do not drive over the crest of a hill without seeing what conditions are on the other side.Do not drive in reverse over a hill without the aid of an observer.
When climbing a steep slope or hill, start in a lower gear rather than downshifting to a lower gear from a higher gear once the ascent has started. This reduces strain on the engine and the possibility of stalling.
If your vehicle stalls, do not try to turn around because this could cause vehicle roll over. It is better to reverse back to a safe location.
Apply just enough power to the wheels to climb the hill. Too much power will cause the tires to slip, spin or lose traction, resulting in loss of vehicle control.
Missing Image
Descend a hill in the same gear you would use to climb up the hill to avoid excessive brake application and brake overheating. Do not descend in neutral. Disengage overdrive or move the transmission selector lever to a lower gear. When descending a steep hill, avoid sudden hard braking as you could lose control. The front wheels have to be turning in order to steer your vehicle.
If your vehicle has anti-lock brakes, apply the brakes steadily. Do not pump the brakes.
Driving on Snow and Ice
  WARNING:  If you are driving in slippery conditions that require tire chains or cables, then it is critical that you drive cautiously. Keep speeds down, allow for longer stopping distances and avoid aggressive steering to reduce the chances of a loss of vehicle control which can lead to serious injury or death. If the rear end of your vehicle slides while cornering, steer in the direction of the slide until you regain control of your vehicle.

Note:  Excessive tire slippage can cause transmission damage.
Four-wheel drive vehicles have advantages over two-wheel drive vehicles in snow and ice but can skid like any other vehicle. Should you start to slide while driving on snowy or icy roads, turn the steering wheel in the direction of the slide until you regain control.
Avoid sudden applications of power and quick changes of direction on snow and ice. Apply the accelerator slowly and steadily when starting from a full stop.
Avoid sudden braking. Although a four-wheel drive vehicle may accelerate better than a two-wheel drive vehicle in snow and ice, it will not stop any faster as braking occurs at all four wheels. Do not become overconfident as to road conditions.
Make sure you allow sufficient distance between you and other vehicles for stopping. Drive slower than usual and consider using one of the lower gears. In emergency stopping situations, apply the brake steadily. Do not pump the brake pedal.
If Your Vehicle Gets Stuck In Mud or Snow
  WARNING:  Do not spin the wheels at over 34 mph (55 km/h). The tires may fail and injure a passenger or bystander.

If your vehicle gets stuck in mud or snow, you may rock it out by shifting between forward and reverse gears, stopping between shifts in a steady pattern. Press lightly on the accelerator in each gear.
Note:  Do not rock your vehicle if the engine is not at normal operating temperature, damage to the transmission may occur.
Note:  Do not rock your vehicle for more than a minute, damage to the transmission and tires may occur or the engine may overheat.
Parking
  WARNING:  If the parking brake is fully released, but the brake warning lamp remains illuminated, the brakes may not be working properly. Have your vehicle checked as soon as possible.
  WARNING:  Always fully apply the parking brake. Make sure you shift into park (P) for vehicles with an automatic transmission. Switch the ignition off and remove the key whenever you leave your vehicle.

On some four-wheel drive vehicles, when the transfer case is in the neutral (N) position, the engine and transmission disconnect from the rest of the driveline. Therefore, your vehicle is free to roll even if the automatic transmission is in park (P) or the manual transmission is in gear. Do not leave your vehicle unattended with the transfer case in the neutral (N) position. Always set the parking brake fully and turn off the ignition when leaving your vehicle.
Maintenance and Modifications
The suspension and steering systems on your vehicle have been designed and tested to provide predictable performance whether loaded or empty. For this reason, we strongly recommend that you do not make modifications such as adding or removing parts (for example, lift kits or stabilizer bars) or by using replacement parts not equivalent to the original factory equipment.
We recommend that you use caution when your vehicle has either a high load or device (such as ladders or luggage racks). Any modifications to your vehicle that raise the center of gravity may cause your vehicle to roll over when there is a loss of vehicle control.
Failure to maintain your vehicle correctly may void the warranty, increase your repair cost, reduce vehicle performance and operational capabilities and adversely affect you and your passenger's safety. We recommend you frequently inspect your vehicle's chassis components when your vehicle is subject to off road usage.
