Enhanced Traction System Warning
Light
If your vehicle has the
Enhanced Traction System
(ETS), this warning light
should come on briefly as
you start the engine.
If the warning light doesn’t come on then, have it fixed
so it will be ready to warn you if there’s a problem.
If the warning light stays on, or comes on when you’re
driving, there may be a problem with your Enhanced
Traction System and your vehicle may need service.
When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
The Enhanced Traction System warning light may come
on for the following reasons:
•
If you turn the system off by pressing the ETS
button on the center console near the gear
shift lever, the warning light will come on and stay
on. To turn the system back on, press the button
again. The warning light should go off. See
Enhanced Traction System (ETS) on page 4-9 for
more information.
•
If the traction control system is affected by an
engine-related problem, the system will turn off and
the warning light will come on.
•
If the vehicle is driven on an extremely rough road,
the warning light may come on momentarily but will
go off again when the vehicle leaves the rough
surface.
If the Enhanced Traction System warning light comes
on and stays on for an extended period of time when the
system is turned on and the parking brake is fully
released, your vehicle needs service.
