Differential Lock Indicator Light; Reduced Engine Power Light; Highbeam On Light - Chevrolet T-Series Owner's Manual

Differential Lock Indicator Light

The light will come on momentarily during starting.
If the light fails to come on, have it repaired as
soon as possible so you will be aware when
the lock system is in use.

Reduced Engine Power Light

If your vehicle has this
feature, this light is
located in the center of
the instrument panel.
The light is on when the
inter-axle differential
lock system is in use.
If the check engine and
reduced engine power
lights are on, the throttle
may be disabled, and
a noticeable change
in the vehicle's
performance may occur.
If the reduced engine power light is on, but there
is no change 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 slower speed while the reduced
engine power light is on, but acceleration
and speed may be limited.
Anytime the check engine light stays on, the
vehicle should be taken to an authorized dealer as
soon as possible for service.

Highbeam On Light

See Headlamp High/Low-Beam Changer on
page 88.
This light comes on
when the high-beam
headlamps are in use.
