Note:
The AdvanceTrac® with RSC® stability
enhancement system can be switched off
by deselecting the feature on the instrument
panel. See Using Traction Control (page
247). This disables the engine management
feature, allowing the vehicle to maintain full
power and enhanced momentum through
the obstacle.
Note: The AdvanceTrac system can take
control of the transfer case clutch and
disable it during driving maneuvers when
necessary.
2H - 4X2
This turns on when you select normal or
conserve. Power is delivered to the rear
wheels only. This mode is appropriate for
normal on-road driving on dry pavement and
provides the best fuel economy. 4A - 4X4 Auto
This turns on when you select excite, normal,
4x4 auto or slippery. It provides electronically
controlled four-wheel drive with power
delivered to all four wheels, as required, for
increased traction. 4A is calibrated in
conjunction with drive mode. Using 4A in
excite is less aggressively tuned and is
appropriate for dry road surfaces. Using 4A
in normal and 4x4 auto is appropriate for all
on-road driving conditions, such as dry road
surfaces, wet pavement, light snow or gravel.
Using 4A in slippery is more aggressively
tuned and is appropriate for slippery
surfaces, such as light snow or gravel.
4H - 4X4 High
This turns on when you select deep
conditions. It provides electronically 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.4L - 4X4 Low (If Equipped)
This turns on when you select slow climb. It
provides electronically locked four-wheel
drive power to both the front and rear wheels
for use on low traction surfaces, but does so
with additional gearing for increased torque
multiplication. Intended only for off-road
applications such as deep sand, steep slopes
or pulling heavy objects. Using 4L does not
engage when your vehicle is moving above
3 mph (5 km/h)
. This is normal and is no
reason for concern.
Shifting Between Four-Wheel Drive System
Modes
Note: Momentarily releasing the accelerator
pedal when a shift in progress message
displays improves engagement and
disengagement performance.
Note: Do not perform this operation if the
rear wheels are slipping.
Note: You may hear some noise as the
system shifts or engages, This is normal.

TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications WARNING: When you install a wheel, always remove any corrosion, dirt or foreign m\
aterials present on the mounting surfaces of the
wheel or the surface of the wheel hub, brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners that attach
the rotor to the hub so they do not interfere with the mounting surfaces\
of the wheel. Installing wheels without correct metal-to-metal contact
at the wheel mounting surfaces can cause the wheel nuts to loosen and th\
e wheel to come off while your vehicle is in motion, resulting in
loss of vehicle control, personal injury or death. lb.ft (Nm)
