Saturn 2009 SKY, Owner'S Manual

Page: 182 / 358

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” 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 4-21.
To turn the system off or
on, press and release the
ESC/TCS button located
on the instrument panel.
The DIC will display the appropriate message the button
is pressed.
Traction Control Operation
Traction control limits wheel spin by reducing engine
power to the wheels (engine speed management)
and by applying brakes to each individual wheel
(brake-traction control) as necessary.
The traction control system is enabled automatically
when the vehicle is started, and it will activate and flash
the ESC/TCS light and display the LOW TRACTION
message if it senses either of the rear wheels are
spinning or beginning to lose traction while driving.
For more information on the LOW TRACTION message,
see Driver Information Center (DIC) on page 3-34.
Notice: If the wheel(s) of one axle are allowed to
spin excessively while the ESC/TCS, ABS and
Brake warning lights and the SERVICE ESC and/or
SERVICE TRACTION messages are displayed,
the differential could be damaged. The repairs
would not be covered by the vehicle warranty.
Reduce engine power and do not spin the wheel(s)
excessively while these lights and this message
are displayed.
