Traction Control System (Tcs) - Chevrolet 2011 HHR Owner's Manual

When the ESC system is turned off, the TRACTION
OFF and ESC OFF messages appear, and the
ESC/TCS light comes on to warn the driver that
both traction control and ESC are disabled.
It is recommended that the system remain on for normal
driving conditions, but it may be necessary to turn the
system off if the vehicle is stuck in sand, mud, ice or
snow, and you want to rock your vehicle to attempt to
free it. It may also be necessary to turn off the system
when driving in extreme off-road conditions where high
wheel spin is required. See If Your Vehicle is Stuck in
Sand, Mud, Ice, or Snow on page 5 22.
ESC may also turn off automatically if it determines
that a problem exists with the system. The ESC OFF
and SERVICE ESC messages and the ESC/TCS light
comes on to warn the driver that ESC is disabled and
requires service. If the problem does not clear after
restarting the vehicle, see your dealer for service. See
DIC Warnings and Messages on page 4 41 for more
information.
Adding non dealer/non retailer accessories can affect
the vehicle's performance. See Accessories and
Modifications on page 6 3 for more information.

Traction Control System (TCS)

The vehicle has a Traction Control System (TCS) that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that the front wheels are spinning too much or are
beginning to lose traction. When this happens, the
system works the front brakes and reduces engine
power by closing the throttle and managing engine
spark to limit wheel spin.
The system may be heard or felt while it is working.
This is normal and does not mean there is a problem
with the vehicle.
See Electronic Stability Control (ESC)/Traction Control
System (TCS) Indicator/Warning Light on page 4 31 for
more information.
