Pontiac 2008 G5 Owner's Manual page 201

If your vehicle is in cruise control while TCS begins to
limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, the cruise control can be re-engaged. See
Turn Signal/Multifunction Lever on page 3-7.
Adjust your driving accordingly. See DIC Warnings and
Messages on page 3-44 for more information.
The Traction Control System is automatically enabled
whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should always
leave the system enabled. You can turn TCS off if you
ever need to.
When this light is on and
either the SERVICE
TRACTION or TRACTION
OFF message is
displayed, the system will
not limit wheel spin.
It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn
the system off if your 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 4-24.
The DIC displays the appropriate message as described
previously when the button is pressed.
To turn the system off or
on, press and release the
ESC/TCS button located
on the instrument panel.
