Service Four-Wheel Drive

Warning Light

The service four-wheel drive light comes on,
except for the SS model, to indicate that there may
be a problem with the drive system and service
is required. Malfunctions can be indicated by
the system before any problem is apparent, which
may prevent serious damage to the vehicle.
This system is also designed to assist your
GM dealer in correctly diagnosing a malfunction.

This light should come
on briefly when you turn
on the ignition, as a
check to show you
it is working.

Check Gages Warning Light

If the light comes on and stays on while you are
driving, check your coolant temperature and
engine oil pressure gages to see if they are in the
warning zones.

Gate Ajar Light

Close the liftgate or liftglass. Never drive with the
liftgate or liftglass even partially open.
The check gages light
will come on briefly
when you are starting
the engine.
If this light comes on,
the liftgate or liftglass is
not completely shut.
