9-54 Driving and Operating
Notice: If the wheel(s) of one axle
is allowed to spin excessively
while the StabiliTrak
® , ABS, brake
warning lights, and any relevant
DIC messages are displayed, the
transfer case could be damaged.
The repairs would not be covered
by the vehicle warranty. Reduce
engine power and do not spin the
wheel(s) excessively while these
lights and messages are
displayed.
The traction control system may
activate on dry or rough roads or
under conditions such as heavy
acceleration while turning or abrupt
upshifts/downshifts of the
transmission. When this happens, a
reduction in acceleration may be
noticed, or a noise or vibration may
be heard. This is normal.
If cruise control is being used when
the system activates, the StabiliTrak
light will flash and cruise control will
automatically disengage. Cruise
control may be reengaged when
road conditions allow. See Cruise
Control on page 9‑55.
StabiliTrak may also turn off
automatically if it determines that a
problem exists with the system.
If the problem does not clear itself
after restarting the vehicle, see your
dealer for service.
Locking Rear Axle
Vehicles with a locking rear axle can
give more traction on snow, mud,
ice, sand, or gravel. It works like a
standard axle most of the time, but
when traction is low, this feature will
allow the rear wheel with the most
traction to move the vehicle.
Continuous Damping
Control (CDC)
This vehicle may have a continuous
damping control system called
Autoride
® . With this feature,
improved vehicle ride and handling
is provided under a variety of
passenger and loading conditions.
Autoride is fully automatic and
uses a computer controller to
continuously monitor vehicle speed,
wheel to body position, lift/dive,
and steering position of the vehicle.
The controller then sends signals
to each shock absorber to
independently adjust the damping
level to provide the optimum
vehicle ride.
Autoride also interact with the tow/
haul mode that, when activated, will
provide additional control of the
shock absorbers. This additional
control results in better ride and
handling characteristics when the
vehicle is loaded or towing a trailer.
See “Tow/Haul Mode” under Trailer
Towing on page 9‑77 for more
information.
Automatic Level Control
The automatic level control rear
suspension is available on light‐duty
vehicles and comes as a part of the
Continuous Damping Control (CDC)
suspension, if equipped.
