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 3-10.

This light will come on
when your Enhanced
Traction System is limiting
wheel spin. See
Enhanced Traction System
Active Light on page 3-29.
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 2-24.
See Enhanced Traction System Warning Light on
page 3-28. When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.
When the system is on
and the parking brake is
fully released, this warning
light will come on to let
you know if there's a
problem.
