Enhanced Traction System Warning Light
(If Equipped)
ETS
OFF
With 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 it 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 button on
the 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" in the Index for
more information.)
The warning light will come on when you set your
parking brake with the engine running, and it will
stay on if your parking brake doesn't release fully.
If the system is turned on and the warning light stays
on after your parking brake is fully released, it
means there's
a
problem with the system.
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.
