Traction Control System (TCS)
Your vehicle may have a traction control system
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 transaxle and apply the front
brakes to limit wheel spin.
This light will flash
when your traction
control system is limiting
wheel spin.
You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when the
traction control system begins to limit wheel spin,
the cruise control will automatically disengage.
When road conditions allow you to safely
use it again, you may re-engage the cruise
control. See Cruise Control on page 155.
The traction control system operates in all transaxle
shift lever positions. But the system can upshift the
transaxle only as high as the shift lever position
you’ve chosen, so you should use the lower gears
only when necessary. See Automatic Transaxle
Operation on page 117.
When the system is on,
this warning light will
come on and stay on to
let you know if there’s
a problem.
A SERVICE TRACTION CONTROL message will
also appear on the DIC. When this warning
light is on, the system will not limit wheel spin.
Adjust your driving accordingly. See DIC Warnings
and Messages on page 197 for more information.
To limit wheel spin, especially in slippery road
conditions, you should always leave the traction
control system on. But you can turn the system off
if you ever need to. You should turn the system
off if your vehicle ever gets stuck in sand, mud or
snow and rocking the vehicle is required.
