It may also be necessary to turn off
the system when driving in extreme
off-road conditions where high wheel
spin is required. See If Your Vehicle
is Stuck in Sand, Mud, Ice, or Snow
on page 4-16.
Traction Control Operation
The traction control system is part
of the StabiliTrak system. Traction
control limits wheel spin by reducing
engine power to the wheels (engine
speed management) and by applying
brakes to each individual wheel
(brake-traction control) as necessary.
The traction control system is
enabled automatically when the
vehicle is started. It will activate
and the StabiliTrak light will flash
if it senses that any of the wheels
are spinning or beginning to lose
traction while driving. If traction
control is turned off, only the
brake-traction control portion of
traction control will work. The engine
speed management will be disabled.
In this mode, engine power is not
reduced automatically and the driven
wheels can spin more freely. This
can cause the brake-traction control
to activate constantly.
Notice: If the wheel(s) of one axle
is allowed to spin excessively
while the StabiliTrak, ABS and
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 3-9.
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/retailer for service.
All-Wheel Drive (AWD)
System
If the vehicle has this feature, engine
power is sent to all four wheels when
extra traction is needed. This is like
four-wheel drive, but there is no
separate lever or switch to engage
or disengage the axle. It is fully
automatic, and adjusts itself as
needed for road conditions.
