Pontiac 2004 Grand Am - Manual (Page 135)

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.
Enhanced Traction System
Active Light
If your vehicle has the
Enhanced Traction System
(ETS), this light will
come on when the system
is limiting wheel spin.
Slippery road conditions may exist if the Enhanced
Traction System active light comes on, so adjust your
driving accordingly.
The light will stay on for a few seconds after the
Enhanced Traction System stops limiting wheel spin.
The Enhanced Traction System active light also comes
on briefly when you turn the ignition key to ON. If
the light doesn’t come on then, have it fixed so it will be
there to tell you when the system is active.
