Reduced Engine Power Warning Light
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 SERVICE ENGINE SOON light stays on,
the vehicle should be taken to an authorized GM dealer
as soon as possible for service.
If the SERVICE ENGINE
SOON and REDUCED
ENGINE POWER lights are
on, a noticeable reduction in
the vehicle's performance
may occur.
Air Pressure Gage (If Equipped)
The yellow pointer shows the pressure available for the
front system, while the green pointer shows pressure for
the rear. There should be no more than 4 psi (28 kPa)
difference showing between the systems.
Don't drive until both pointers are showing at least
120 psi (830 kPa), so you'll have enough air if you need
to apply your brakes.
If your vehicle has air
brakes, this gage located on
the instrument panel cluster
shows the air pressure for
both your front and rear
brake systems.
