3-58 Instrument Panel

The traction control system is
enabled automatically when the
vehicle is started. It will activate and
the StabiliTrak light will ash 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 ash and cruise control
will automatically disengage. Cruise
control may be reengaged when
road conditions allow. SeeCruise
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.
When using a compact spare tire
on the AWD equipped vehicle,
the AWD system automatically
detects the presence of the compact
spare and the AWD is disabled.
To restore the AWD operation and
prevent excessive wear on the
AWD system, replace the compact
spare with a full-size tire as
soon as possible. SeeCompact
Spare Tire on page 5-81for more
information.
