USING FOUR-WHEEL DRIVE
Note: For important information regarding
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 and 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 does not damage
drive components.
Note: If 4L mode is selected when your
vehicle is moving above 3 mph (5 km/h),
the 4WD system does not perform a shift.
This is normal and should be no reason for
concern. Refer to Shifting to or from 4L for
proper operation.

CHECK 4X4
Displays when a 4X4 system
fault is present.
Note: When a 4X4 system fault is present,
the system typically remains in whichever
4WD mode was selected prior to the fault
condition occurring. It does not default to
4X2 in all circumstances. When this warning
is displayed, have your vehicle serviced by
an authorized dealer.
4WD Switch Selections
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.
Note: If your vehicle is equipped with
AdvanceTrac® with RSC®, the system
automatically turns off the stability
enhancement feature when you shift the
4WD system into 4L - 4X4 LOW. You can
manually turn the system off by pressing
the AdvanceTrac button. See Using
Traction Control (page 219). This turns off
the engine management feature, allowing
the vehicle to maintain full power and
enhanced momentum through the obstacle.
The brake traction enhancement feature is
still turned on.
Note: The AdvanceTrac system has the
ability to take over control of the transfer
case clutch and disable it during driving
maneuvers when necessary.
Note: 4WD mode availability is based on
Drive Mode selection. See Drive Control
(page 266).
