fuel pump PONTIAC BONNEVILLE 1993 Owners Manual

Fuel Gage
You will either have this fuel gage or
one very similar. Your fuel gage tells
you about how much fuel you have left,
when
the ignition is on. When the gage
reads in the yellow band, a warning
chime will sound and the
CHECK
GAGES warning light will go on, if you
have it.
Here are five things that some owners
ask about. None of these show a
problem with your fuel gage:
At the gas station, the gas pump shuts
off before the gage reads
F (Full).
It takes a little more or less fuel to fill
up than the gage indicated. For
example, the gage may have indicated
the
tank was half full, but it actually
took a little more or less than half the
tank's capacity to fill the tank.
The gage moves a little when you turn
a corner or speed up.
The gage doesn't go back to E (Empty)
when you turn off the ignition.
If you have the large span (220") gage,
the needle moves more for a given
amount
of fuel. This does not indicate
excessive fuel consumption, and is
normal.
For your fuel
tank capacity, see Sewice
Station Informution
on the last page of
this manual.
Engine Coolant Temperature
Gage
(OPTION)
A coolant temperature gage shows the
engine coolant temperature.
If the gage pointer moves into the red
warning area, your engine is too hot!
The
CHECK GAGES light will go on
and a warning chime will sound, if you
have this option. It means that your
engine coolant has overheated. If you
have been operating your vehicle under
normal driving conditions, you should
pull off the road, stop your vehicle and
turn off
the engine as soon as possible.
HOT COOLANT CAN
BURN YOU
BADLY! In Problems on the Road, this
manual shows what to do. See the
Index
under Engine Overheating.

“Riding” your brakes can
1 cause them to overheat to the
point that they won’t work well.
You might not be able to stop your
vehicle in time to avoid an
accident. If you “ride” your
brakes, they will get so hot they
will require a lot of pedal force to
sIow you down. Avoid “riding” the
brakes.
’
I NOTICE I
“Riding” the brakes wears them
out much faster. You would need
costly brake replacement much sooner than normal, and
it also
reduces fuel economy.
!
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.
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
Your Pontiac has an advanced electronic
braking system that will help prevent
skidding.
