Traction Control System (Tcs) - Chevrolet 2009 Cobalt Owner's Manual

Launch Control (SS Models Only)
Launch Control is a form of traction control, to control
tire spin while launching the vehicle during closed track
events and competitive driving. The feature is activated
when the vehicle is at rest while in Competitive Mode.
At rest, if the accelerator pedal is pressed to the
floor with the clutch engaged, the RPM is limited to a
predetermined level. A smooth, quick release of
the clutch while keeping the accelerator pedal on the
floor will provide controlled wheel spin for consistent
acceleration. If the vehicle is equipped with a manual
transmission, complete shifts as described in Manual
Transmission Operation on page 2-28.
LAUNCH CONTROL displays in the DIC after the
COMPETITIVE MODE message, when the vehicle is
stopped. The system will exit to COMPETITIVE MODE
after the vehicle is launched. See "Competitive Driving
Mode" earlier in this section. The normal Traction
Control System (TCS) will not be operating while in the
Competitive Driving mode and the TCS light on the
instrument panel cluster comes on. Adjust your driving
accordingly. See DIC Warnings and Messages on
page 3-46 for more information.

Traction Control System (TCS)

The vehicle may have 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 3-31
for more information.
This light flashes while the
traction control system is
limiting wheel spin.
