USING FOUR-WHEEL DRIVE
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. 4X4 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 4X4 low is selected while the
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 pulling the
4WD control (4WD vehicles) or turning the
electronic locking differential control (2WD
vehicles). See
Electronic Locking
Differential (page 225).
Manual Shift On Stop (MSOS)
4WD system
(If Equipped)
Note: The vehicle should not be driven in
4X4 High or 4X4 Low modes with the hub
locks set to FREE as this condition may
damage driveline system components. The 4WD system is engaged or disengaged
by rotating the control for both front wheel
hub locks from the FREE or LOCK position,
then manually engaging or disengaging the
transfer case with the floor-mounted
shifter. For increased fuel economy in 2WD,
rotate both hub locks to the FREE position.
Electronic Shift-On-the-Fly
(ESOF) 4WD system
(If Equipped)
Note: If 4X4 Low is selected while the
vehicle is moving above
3 mph (5 km/h),
the 4WD system will not perform a shift.

completely clockwise; to engage AUTO,
turn the hub locks completely
counterclockwise.
The ESOF 4WD system:
•
provides 4x4 High engagement and
disengagement while the vehicle is
moving.
• is operated by a rotary control located
on the instrument panel that allows
you select 4x2, 4x4 High or 4x4 Low
operation.
• uses auto-manual hub locks that can
be engaged and disengaged
automatically based on the 4x4 mode
selected.
• will increase fuel economy when used
in the hub lock's recommended AUTO
mode.
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.
4X2 Momentarily illuminates when
2H is selected.
4X4 HIGH Continuously illuminates when
4H is selected. 4X4 LOW Continuously illuminates when
4L is selected.
CHECK 4X4 Displays when a 4X4 fault is
present.
Using a Manual Shift On Stop
(MSOS) 4WD system (If Equipped)
Note: High shift efforts may be encountered
when attempting to shift into and out of 4x4
modes. It is recommended to allow the
vehicle to roll at a speed below
3 mph
(5 km/h) when shifting between modes. 2H (4X2)

applications such as deep sand, steep
grades or pulling heavy objects.
Shifting between system modes
Note:
Do not perform these operations if
the rear wheels are slipping or when
applying the accelerator pedal.
Note: Some noise may be heard as the 4x4
system shifts or engages. This is normal. In
order to reduce engagement noise, it is
recommended that all shifts be performed

If Shift Delayed Pull Forward appears in
the information display, transfer case gear
tooth blockage is present. To alleviate this
condition, place the transmission in a
forward gear, move the vehicle forward
approximately
5 ft (1.5 m), and shift the
transmission back to neutral 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
the 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: Your vehicle may be equipped with
a front air dam that can become damaged
(due to reduced ground clearance) when
taking your vehicle off-road. This air dam
can be taken off by removing 15 bolts.
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.
Power is supplied to all four wheels
through a transfer case. On four-wheel
drive vehicles, the transfer case allows you
to select 4WD when necessary.
Information on transfer case operation and
shifting procedures can be found in this
chapter. Information on transfer case
maintenance can be found 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 the
vehicle. This increases traction, enabling
you to drive over terrain and road
conditions that a conventional two-wheel
drive vehicle cannot.
