You may feel or hear the system working, but this is
normal. This light will also come on when the anti-lock
brake system is working.
If your vehicle is in cruise control when the enhanced
traction 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 3-11.
The Enhanced Traction 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 2-20.
This light, located on the
instrument panel cluster,
will come on when
your Enhanced Traction
System is limiting
wheel spin. See Enhanced
Traction System Active
Light on page 3-29.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave the Enhanced
Traction System on. But you can turn the system off if
you prefer.
When the system is on
and the parking brake is
fully released, this warning
light, located on the
instrument panel cluster,
will come on to let you
know if there's a problem.
