9-26 Driving and Operating
Ride Control Systems
Traction Control
System (TCS)
The 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 reduces engine power and
may also upshift the transmission
and apply the front brakes to limit
wheel spin.
This light will flash when the TCS is
limiting wheel spin.
The system may be heard or felt
while it is working, but this is
normal.
If cruise control is being used when
TCS begins to limit wheel spin, the
cruise control will automatically
disengage. Cruise control may be
reengaged when road conditions
allow. See Cruise Control on
page 9‑29.
The TCS operates in all
transmission shift lever positions.
But the system can upshift the
transmission only as high as the
shift lever position chosen, so use
the lower gears only when
necessary. See Automatic
Transmission on page 9‑21.
When the system is on, this warning
light comes on and stays on if there
is a problem.
A SERVICE TRACTION CONTROL
message also appears on the DIC.
When this warning light is on, the
system will not limit wheel spin.
Adjust your driving accordingly. See
Ride Control System Messages on
page 5‑31 for more information.
To limit wheel spin, especially in
slippery road conditions, TCS
should always be left on. But the
system can be turned off if needed.
Turn the system off if the vehicle
gets stuck in sand, mud, or snow
and rocking the vehicle is required.
See If the Vehicle Is Stuck on
page 9‑8 for more information.
