If the brake traction-control system activates constantly or
if the brakes have heated up due to high-speed braking,
brake traction-control will be disabled and the TRACTION
CONTROL ACTIVE message will be displayed. In the
limited mode, the traction control system will only use
engine traction-control and is limited in its ability to
provide optimal performance since the system will not
utilize brake traction-control to control slip on the drive
wheels. The system will return to normal operation after
the brakes have cooled. This can take up to two minutes
or longer depending on brake usage.
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 you may
notice a reduction in acceleration, or may hear a noise
or vibration. This is normal.
If your vehicle is in cruise control when the system
activates, the STABILITY CONTROL ACTIVE message
will appear on the DIC and the cruise control will
automatically disengage. When road conditions allow
you to use cruise again, you may re-engage the cruise
control. See Cruise Control on page 3-10.

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,
you should see your dealer for service.
All-Wheel Drive (AWD) System
If your vehicle has all-wheel drive (AWD), the AWD
system operates automatically without any action
required by the driver. If the front drive wheels begin
to slip, the rear wheels will automatically begin to drive
the vehicle as required. There may be a slight
engagement noise during hard use but this is normal.
During heavy AWD applications, the engine torque
may be reduced to protect AWD system components.
If the vehicle is exposed to extended heavy AWD usage,
the AWD system will shut itself off to protect the system
from overheating. When the system cools down, the
AWD system will activate itself again automatically; this
cool-down can take up to 20 minutes depending on
outside temperature and vehicle use.
