Pontiac 2010 Automobile User Manual


 
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” the 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 5-23.
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/retailer for service. See DIC
Warnings and Messages on page 4-38 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 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.
This light flashes while the
traction control system is
limiting 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 4-28
for more information.
