Traction Control System (TCS)
If the vehicle has a 5.3L V8 engine, it has 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 one or both of the
front wheels are spinning or beginning to lose traction.
When this happens, the system works the front
brakes and reduces engine power to limit wheel spin.
This symbol, along with the
TRACTION CONTROL
ACTIVE message, comes
on the DIC screen when
the system is active.
You may feel or hear the system working, but this
is normal.
This symbol, along with
the message TRACTION
CONTROL OFF will
display in the DIC for
three seconds when
the traction control
system is disabled.
If there is a problem with the system, the service
traction system will also appear on the DIC. When
these symbols and messages appear on the instrument
panel and the DIC, the system will not limit wheel
spin. Adjust driving accordingly.
The traction control system automatically comes
on whenever the vehicle is started. To limit wheel
spin, especially in slippery road conditions, always
leave the system on. But the traction control system
can be turned off if needed. The system should
be turned off if the vehicle ever gets stuck in sand,
mud, or snow and rocking the vehicle is required.
See Rocking Your Vehicle to Get It Out on page 4-22
and If Your Vehicle is Stuck in Sand, Mud, Ice, or
Snow on page 4-21 for more information.
Press the traction
control button located
on the console to turn
the system off.
If the system is limiting wheel spin when the traction
control button is pressed, the system will turn off
instantly. Turn the system back on at any time by
pressing the button again.
