Notice:When traction control is turned off,
or Competitive Driving Mode is active, it is
possible to lose traction. If you attempt to shift
with the rear wheels spinning with a loss of
traction, it is possible to cause damage to the
transmission. Do not attempt to shift when the
rear wheels do not have traction. Damage
caused by misuse of the vehicle is not covered.
See your warranty book for additional
information.
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 ESC/TCS light will ash and the
cruise control will automatically disengage. When
road conditions allow you to use cruise control
again, you may re-engage the cruise control. See
Cruise Control on page 115.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modi cations on page 235for more information.Limited-Slip Rear Axle
Your vehicle may have a limited-slip rear
differential which provides maximum power and
performance. It is designed to give you additional
traction on snow, mud, ice, sand or gravel. It
works like a standard axle most of the time, but
when one of the rear wheels has no traction
and the other does, this feature will allow
the wheel with traction to move the vehicle.
During a sudden shift, such as shifting from
FIRST (1) to SECOND (2) gear at low engine
speeds or suddenly applying the clutch, you may
feel or hear a clunking or rattling noise. This is
normal.
Electronic Stability Control
Your vehicle may be equipped with an Electronic
Stability Control (ESC) system which combines
antilock brake, traction and stability control
systems and helps the driver maintain directional
control of the vehicle in most driving conditions.
When you rst start your vehicle and begin to drive
away, the system performs several diagnostic
checks to ensure there are no problems. You may
hear or feel the system working.
