Reduced Engine Power Light
If the reduced engine
power light is on, a chime
will sound and a noticeable
reduction in the vehicle’s
performance may occur.
Highbeam On Light
This light comes on when
the high-beam headlamps
are in use.
If the reduced engine power light is on, but there is no
reduction in performance, proceed to your destination.
The performance may be reduced the next time the
vehicle is driven. The vehicle may be driven at a reduced
speed while the reduced engine power light is on, but
acceleration and speed may be reduced.
Anytime the reduced engine power light stays on,
the vehicle should be taken to an authorized GM
dealer/retailer as soon as possible for service.
See Headlamp High/Low-Beam Changer on page 3-8
for more information.
Headlamps Suggested Light
This light will come
on when the use of
headlamps is suggested.
