Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light
on can lead
to an accident.
If the light is still on after you’ve
pulled off the road and stopped carefully, have
the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come
on when you set your parking brake. The
light will stay on
if your parking brake doesn’t release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.
Anti-Lock Brake System Warning Light
ANTI -
LOCK
United States
Canada
With the anti-lock brake system, this light
will
come on when you start
your engine and may stay
on for several
seconds.
That’s normal.

Downloaded from www.Manualslib.com manuals search engine If the light stays on, or comes on when you’re driving,
your vehicle needs service. If the regular brake system
warning light isn’t on, you still have brakes, but you
don’t have anti-lock brakes. If the regular brake system
warning light is also on, you don’t have anti-lock brakes
and there’s a problem with your regular brakes. See
“Brake System Warning Light” earlier
in this section.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn
you if there is a problem.
Daytime Running Lamps Indicator Light
You may have this light on
the instrument panel. It will
light whenever
the DRL are
on.
It is also a reminder to
turn on your headlamps when driving at night. For
more details about DRL, see
“Headlamps and Vehicle
Lighting” in this section.
Malfunction Indicator Lamp (Service
Engine Soon Light) (Gasoline Engine)
Your vehicle is equipped
with
a computer which
monitors operation of the
fuel, ignition and emission
control systems.
SERVICE
ENGINE SOON
This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions
are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment.
(In Canada, OBD IT is replaced by
Enhanced Diagnostics.) The SERVICE
ENGINE SOON
light comes on to indicate that there is a problem and
service is required. Malfunctions often
will be indicated
by the system before any problem is apparent. This may
prevent more serious damage to
your vehicle. This
system is
also designed to assist your service technician
in correctly diagnosing any malfunction.

Downloaded from www.Manualslib.com manuals search engine Center High-Mounted Stoplamp
Your vehicle’s center high-mounted stoplamp is located
above the
rear doors at the center of the vehicle. If
items are loaded
on the roof of the vehicle, as in a
luggage carrier, care should be taken not to block or
damage the center high-mounted stoplamp unit.
If you tow a trailer that is equipped with provisions for a
center high-mounted stoplamp, see your
GM dealer for
instructions on how to make it operate with your
vehicle’s electrical system.
As with any electrical system
modification, have the work performed by a qualified
electrical service person.

objects. This helps air to circulate throughout
your vehicle.
Your vehicle has air vents in the center and
on the sides
of your instrument panel.
You can move the vents from side to side or up and
down to direct the flow of air,
or close the vents
altogether. When you close a vent, it will increase the
flow of air coming out
of any vents that are open.
