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 transaxle. 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.
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,
you should see your dealer/retailer for service.

Power Steering

If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.

Steering Tips

It is important to take curves at a reasonable speed.
Traction in a curve depends on the condition of the tires
and the road surface, the angle at which the curve is
banked, and your speed. While in a curve, speed is the
one factor you can control.
If you need to reduce speed, do it before you enter the
curve, while the front wheels are straight ahead.
Try to adjust the speed so you can drive through the
curve. Maintain a reasonable, steady speed. Wait
to accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
