Traction Control Operation - Chevrolet 2011 HHR Owner's Manual

Traction Control Operation

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, and it will activate and flash
the ESC/TCS light and display the LOW TRACTION
message if it senses that either of the front wheels are
spinning or beginning to lose traction while driving. For
more information on the LOW TRACTION message,
see Driver Information Center (DIC) on page 4 38.
Notice: If the wheel(s) of one axle are allowed to
spin excessively while the ESC/TCS, ABS and
Brake warning lights and the SERVICE ESC and/or
SERVICE TRACTION messages are displayed, the
differential 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 this message
are displayed.

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 drive wheels spinning with a loss of
traction, it is possible to cause damage to the
transmission. Do not attempt to shift when the
drive wheels do not have traction. Damage caused
by misuse of the vehicle is not covered. See the
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, a reduction in
acceleration may be noticed or a noise or vibration may
be heard. This is normal.
If the vehicle is in cruise control while the system
activates, the ESC/TCS light flashes and the cruise
control automatically disengages. The cruise control
can be re-engaged when road conditions allow. See
Cruise Control on page 4 8.
Adding non dealer/non retailer accessories can affect
the vehicle's performance. See Accessories and
Modifications on page 6 3 for more information.
