Fuel Gage

Your fuel gage shows about
how much
fuel is in your
tank. It works
only when
the engine is on. When the
indicator nears
“E,” you
still have a little fuel left.
You need to get more right
away.
Here are
four concerns some owners have had about the
fuel gage. All these situations are normal and indicate
nothing wrong with the
fuel gage.

but
it took more -- or less -- than half of the tank’s
capacity
to fill it.
e It takes more (or less) gas to fill up than the gage

up, or stop your vehicle.
When
you turn the engine off, the gage doesn’t go all

Malfunction Indicator Lamp
(Service Engine Soon Light)
A computer monitors operation of your fuel, ignition
and emission control systems. This light should come

when the ignition is on, but the engine is not running, as
a check
to show you it is working. If it does not come on
at all, have it fixed right away.
If it stays on, or it comes
on while you are driving, the computer is indicating that
you have a problem. You should take your vehicle in for

AM Stereo
This means the DelcoB system can receive C-QUAM@
stereo broadcasts. Many AM stations around the country
use C-QUAM@
to produce stereo, though some do not.
(C-QUAM@ is a registered trademark

If your Delcoa system can get C-QUAM@, your
“STEREO” light will come on when you’re receiving it.

If you keep pace with the traffic and allow realistic
following distances, you will eliminate a lot of
unnecessary braking. That means better braking and
longer brake life.
0 If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes.
If you do, the
pedal may get harder to push down.
If your engine
stops, you will still have some power brake assist.
But you will
use it when you brake. Once the power
assist is used up, it may take longer to stop and the
brake pedal will be harder to push.
Anti-Lock Brakes (Option)
If your Buick has this system, your Buick has an
advanced electronic braking system that will help
prevent skidding.
If you have an anti-lock brake system (ABS), the brake
pedal will say
so. And this light on the instrument panel
will go
on when you start your vehicle.
When you start your vehicle
and begin to drive away,
you may hear a momentary motor or clicking noise. And
you may even notice that your brake pedal moves a little
while this is going on. This is the
ABS system testing
itself. If you have your foot
on the brake pedal, this
check won’t happen until the vehicle goes about
4 mph
(6 km/h) or until you take your foot off the brake pedal.
After an
ABS stop, you may hear a clicking noise the
next time the vehicle goes about 4 mph (6 km/h).
