4X4 LOW (4WD Low)- Uses extra gearing to provide maximum power
to all four wheels. Intended onlyfor off-road applications such as deep
sand, steep grades or pulling heavyobjects. 4L (4WD Low) will not
engage while the vehicle is moving; this is normal and should be no
reason for concern. Refer toShifting to/from 4L (4WD Low)for proper
operation.
Shifting between 2WD (2WD High) and 4X4 HIGH (4WD High)
•Move the 4WD control between 2WD and 4X4 HIGH at anyforward
speed.
Note:Do not perform this operation at speeds above 72 km/h (45 mph)
if the outside temperature is below 0°C (32°F).
Note:Do not perform this operation if the rear wheels are slipping.
Shifting to/from 4X4 LOW (4WD Low)
1. Bring the vehicle to a complete stop
2. Depress the brake
3. On vehicles equipped with an automatic transmission, place the
transmission in N (Neutral); on vehicles equipped with a manual
transmission, depress the clutch.
4. Move the 4WD control to the desired position.
•If shifting into 4X4 LOW (4WD Low), wait for the LOW RANGE light
in the instrument cluster to turnonindicating the shift is complete.
•If shifting out of 4X4 LOW (4WD Low), wait for the LOW RANGE light
in the instrument cluster to turnoffindicating the shift is complete.
Driving off-road with truck and utility vehicles
4WD vehicles are speciallyequipped 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.
How your vehicle differs from other vehicles
Truck and utilityvehicles can differ from some other vehicles. Your
vehicle maybe higher to allow it to travel over rough terrain without
getting hung up or damaging underbodycomponents.
The differences that make your vehicle so versatile also make it handle
differentlythan an ordinarypassenger car.
Maintain steering wheel control at all times, especiallyin 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.

Vehicles with a higher center of gravitysuch as utilityand
four-wheel drive vehicles handle differentlythan vehicles with a
lower center of gravity. Utility and four-wheel drive vehicles arenot
designed for cornering at speeds as high as passenger cars anymore
than low-slung sports cars are designed to perform satisfactorilyunder
off-road conditions. Avoid sharp turns, excessive speed and abrupt
maneuvers in these vehicles. Failure to drive cautiouslycould result in
an increased risk of loss of vehicle control, vehicle rollover, personal
injuryand death.
•If the vehicle goes from one type of surface to another (i.e., from
concrete to gravel) there will be a change in the waythe vehicle
responds to a maneuver (steering, acceleration or braking). Again,
avoid these abrupt inputs.
Parking
On some 4WD vehicles, when the transfer case is in the N (Neutral)
position, the engine and transmission are disconnected from the rest of
the driveline. Therefore, the vehicle is free to roll even if the automatic
transmission is in P (Park) or the manual transmission is in gear. Do not
leave the vehicle unattended with the transfer case in the N (Neutral)
position. Always set the parking brake fully and turn off the ignition
when leaving the vehicle.
4WD Systems
4WD (when you select a 4WD mode), uses all four wheels to power the
vehicle. This increases traction, enabling you to drive over terrain and
road conditions that a conventional two-wheel drive vehicle cannot.
Power is supplied to all four wheels
through a transfer case. On 4WD
vehicles, the transfer case allows
you to select 4WD when necessary.
Information on transfer case
operation and shifting procedures
can be found in theDriving
chapter. Information on transfer
case maintenance can be found in theMaintenance and specifications
chapter. You should become thoroughlyfamiliar with this information
before you operate your vehicle.
Normal characteristics
On some 4WD models, the initial shift from two-wheel drive to 4x4 while
the vehicle is moving can cause some momentaryclunk and ratcheting

sounds. This is the front drivetrain coming up to speed and the
automatic locking hubs engaging and is not cause for concern.
Sand
When driving over sand, tryto 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 steadilythrough the terrain. Applythe accelerator slowly
and avoid spinning the wheels.
If you must reduce the tire pressure for whatever reason in sand, make
sure you re-inflate the tires as soon as possible.
Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to 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
If you must drive through high
water, drive slowly. Traction or
brake capabilitymaybe limited.
When driving through water,
determine the depth; avoid water
higher than the bottom of the hubs
(if possible) and proceed slowly. If
the ignition system gets wet, the
vehicle maystall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectivelyas drybrakes. Drying can be improved bymoving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even 4WD vehicles can lose traction in slick mud. As
when you are driving over sand, applythe accelerator slowlyand avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
Driving through deep water may damage the transmission.
Refer toTransmission temperature gaugein theInstrument cluster
chapter for transmission fluid temperature information.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.

Note:Do not exceed the GVWR or the GAWR specified on the
certification label.
Towing trailers beyond the maximum recommended gross trailer
weight exceeds the limit of the vehicle and could result in
engine damage, transmission damage, structural damage, loss of vehicle
control, vehicle rollover and personal injury.
Refer toTransmission temperature gaugein theInstrument cluster
chapter for transmission fluid temperature information.
