Traction Control System (TCS)
Your 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 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. It may also upshift
the transmission to limit wheel spin. You may feel
or hear the system working, but this is normal.
The TRACTION CONTROL ACTIVE message on the
Driver Information Center (DIC) will be displayed
when the system is limiting wheel spin.
If the vehicle is in cruise control when the TCS begins
to limit wheel spin, the cruise control will automatically
disengage. When road conditions allow safe use of
the cruise control, it can be used again. See Cruise
Control on page 3-10.
The TCS operates in all transmission shift lever
positions. But the system can upshift the transmission
only as high as the shift lever position that was chosen,
so use the lower gears only when necessary. See
Automatic Transmission Operation on page 2-27.
This light, along with the
TRACTION CONTROL
OFF message, will
display on the DIC for
three seconds when
the TCS is not on.
If there is a problem with the system, the SERVICE
TRACTION SYSTEM message will also come on in the
DIC. When this warning light is on, the system will not
limit wheel spin. Adjust driving accordingly.
To limit wheel spin, especially in slippery road conditions,
you should always leave the TCS on. But you can turn the
system off if you ever need to. The TCS 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 4-20 and If Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 4-20.
To turn the TCS on or off, press the TCS button located
above the radio.
When the TCS is turned off, the TCS warning light will
come on along with the TRACTION CONTROL OFF
message on the DIC. It will disappear when the TCS is
turned back on. If the TCS is limiting wheel spin when the
TCS button is pressed, the TCS warning light will come
on and the TCS will turn off right away.
