Service All-Wheel Drive Light; Check Gages Warning Light; Gate Ajar Light - Buick 2006 Rainier Maintenance Manual

Service All-Wheel Drive Light

The service all-wheel drive light comes on 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,
your liftgate or liftglass
is not completely shut.
