Chevrolet 2009 Cobalt Owner's Manual page 227

If the vehicle is in cruise control while TCS begins to
limit wheel spin, the cruise control will automatically
disengage. The cruise control can be re-engaged when
road conditions allow. See Turn Signal/Multifunction
Lever on page 3-7.
Adjust your driving accordingly. See DIC Warnings and
Messages on page 3-46 for more information.
The Traction Control System comes on automatically
whenever the vehicle is started. It is recommended
to leave the system 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.
When this light is on and
either the SERVICE
TRACTION or TRACTION
OFF message is displayed,
the system will not limit
wheel spin.
It may also be necessary to turn off the system when
driving in off-road conditions where high wheel spin
is required. See If Your Vehicle is Stuck in Sand, Mud,
Ice, or Snow on page 4-25.
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.
