USING FOUR-WHEEL DRIVE
WARNING
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 will produce
excessive noise, increase tire wear and may
damage drive components. 4H and 4L mode
is only intended for consistently slippery or
loose surfaces.
Note: If 4L mode 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 for
proper operation.
4WD Indicator Lights
The indicator lights illuminate in the
information display in the reconfigurable
telltale (RTT) location under the following
conditions. See Warning Lamps and
Indicators (page 88).
Note: When a 4X4 system fault is present,
the system will typically remain in whichever
4WD 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.

WARNING
Utility and four-wheel drive vehicles
are not designed for cornering at
speeds as high as passenger cars any
more than low-slung sports cars are
designed to perform satisfactorily under
off-road conditions. Avoid sharp turns or
abrupt maneuvers in these vehicles.
Note: If your vehicle is equipped with
AdvanceTrac® with RSC®, the system will
automatically turn 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 175). This will
disable the engine management feature,
allowing the vehicle to maintain full power
and enhanced momentum through the
obstacle. The brake traction enhancement
feature will still be enabled.
Note: The Control Trac® selector switch
should not be changed while the rear wheels
are slipping.
