1996 GMC SAVANA fuel cap

If the Light Is Flashing Are you low on fuel‘?
The following may prevent more serious damage to
your vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
0 Avoid steep uphill grades.
If towing a trailer, reduce the amount of cargo being
hauled as soon as
it is possible.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady“ following.
If the light continues to flash, when it is safe to do so.
stop the vehicle. Put your vehicle in PARK (P). Turn the
key
off, wait at least 10 seconds and restart the engine.
If the light remains on steady, see
“If the Light Is On
Steady” following.
If the light is still flashing follow the
previous steps, and drive the vehicle to your dealer or
qualified service center for service.
If’ the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did
you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be c0rrecte.d when the electrical system
dries out. A few driving trips should turn the light off. As
your engine starts to run
out of fuel, your engine may
not run as efficiently as designed since
s~nall amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly.
It
will take a few driving trips to turn the light off.
Have you recently changed brands of fuel‘?
If so, be sure to fuel your vehicle with quality fuel (see
“FLE~”
in the Index). Poor fuel quality will cause your
engine not to
run as efficiently as designed. You may
notice this as stalling after start-up, stalling when
you put
the vehicle into gear, misfiring, hesitation on acceleration
or stumbling on acceleration. (These conditions may go
away once the engine is warmed up.) This will be
detected by the system and cause the light to turn on.
If you experience this condition, change the fuel brand
you use. It will require at least one full tank of the
proper fuel to
turn the light off.
If none
of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to
fix any mechanical or electrical
problems that
may have developed.

Listed are four situations you may experience with your
fuel gage:
0
0
0
0
At the gas station, the fuel pump shuts off before the
gage reads
FULL (F).
It takes a little more or less fuel to fill up than the
fuel 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 EMPTY (E) when you
turn off the ignition.
None
of these indicate a problem with the fuel gage.
Engine Coolant Temperature Gage

It means that your engine coolant has overheated. If you
have been operating your vehicle under normal
operating conditions, you should pull off the road, stop
your vehicle, and
turn off the engine as soon as possible.
In “Problems on the Road,” this manual shows what to
do. See ”Engine Overheating”
in the Index.

Run your engine only as long as you must. This saves
fuel. When you run the engine, make
it go a little fdster
than just idle. That
is, push the accelerator slightly.
This uses
less fuel for the heat that you get and it
keeps the battery (or batteries) charged. You will need
a well-charged battery (or batteries) to restart the
vehicle, and possibly for signaling later on with your
headlamps. Let the heater
run for awhile.
If you have a diesel engine, you may have to run it at a
higher speed to get enough heat. Then, shut the engine
off and close the window almost all the way to preserve
the heat. Start the engine again and repeat this only
when you feel really uncomfortable from the cold.
But
do it as little as possible. Preserve the fuel as long as you
can. To help keep warm, you can get out of the vehicle
and
do some fairly vigorous exercises every half hour or
so until help comes.

Towin; a Traile
A CAUTION:
If you don’t use the correct equipment and drive
properly, you can lose control when you pull
a
trailer. For example, if the trailer is too heavy, the
brakes may not work
well -- or even at all. You
and your passengers could be seriously injured.
Pull
a trailer only if you have followed all the
steps in this section.
Ask your GM dealer for
advice and information about towing
a trailer
with your vehicle.
NOTICE:
Pulling a trailer improperly can damage your
vehicle and result in costly repairs not covered by
your warranty.
To pull a trailer correctly, follow
the advice in this part, and see your
GM dealer
for important information about towing a trailer
with your vehicle.
Your vehicle can tow
a trailer. To identify what the
vehicle trailering capacity is for your vehicle, you
should read
the information in “Weight of the Trailer”
that appears later
in this section. But trailering is
different than just driving your vehicle by itself.
Trailering means changes
in handling, durability and
fuel economy. Successful, safe trailering takes correct
equipment, and
it has to be used properly.
That’s the reason for this section.
In it are many
time-tested, important trailering tips and safety rules.
Many of these are important for your safety and that of
your passengers. So please read this section carefully
before you pull
a trailer.

L
If you get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline can spray out
on you if you open the
fuel filler cap too quickly.
This spray can happen
if your tank
is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any “hiss” noise to stop. Then unscrew
the cap all the way.
While refueling, hang the cap inside the fuel door.
To take off the cap, turn it slowly to the left
(counterclockwise). Be
careful not
to spill gasoline. Clean gasoline from
painted surfaces
as soon as possible. See “Cleaning the-
Outside of Your Vehicle” in.the Index.

When you put the cap back on, turn it to the right until
you hear at least three clicks. Make sure you fully install
the cap. The diagnostic system can determine if the fuel
cap has been left off
or improperly installed. This would
allow fuel to evaporate int.0 the atmosphere. See
“Malfunction Indicator Lamp”
in the Index.
I NOTICE:
If you need a new cap, be sure to get the right
type. Your dealer can get one for you.
If you get
the wrong type, it
may not fit or have proper
venting, and your fuel tank and emissions system
might be damaged.
Checking Things Under the Hood
To open the hood, first pull
this handle inside the
vehicle. It is just
in front of
the driver’s side door frame
near
the floor.

Engine Oil (Gasoline Engine)
If your vehicle has a diesel engine, see “Engine Oil
(Diesel Engine)” in the Diesel Engine Supplement.
It‘s
a good idea to check your engine oil every time you
be warm and the vehicle must be on level ground.
c‘ Get fuel. In order to get an accurate reading, the oil must
Turn
off the engine and give
the oil
a few minutes to drain
back into the
oil pan. If you
don’t, the oil dipstick might
not show the actual level.
Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push
it back in all the way. Remove it again,
keeping the tip down, and check the level.
When to Add Oil
If the oil is at or below the ADD mark, then ~011’11 need to
add some oil. But you must use the right kind. This part
explains what kind
of oil to use. For crankcase capacity,
see “Capacities and Specifications”
in the Index.
NOTICE:
Don’t add too much oil. If your engine has so much
oil that the oil level gets above the upper mark that
shows the proper operating range, your engine could be damaged.

Inflation -- Tire Pressure
The Certification/Til-e-~ label, which is on the rear edge of
the driver’s door, shows the correct inflation pressures
for your tires when they’re cold. “Cold” means your
vehicle
has been sitting for at least three hours or driven
no 1mre than
1 mile (1.6 ktn).
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation
is all right. It’s not. If your tires
don’t have enough air (underinflation), you can
get the following:
0 Too much flexing
Too much heat
0 Tire overloading
Bad wear
0 Bad handling
Bad fuel economy.
NOTICE: (Continued)
I NOTICE: (Continued) I
If your tires have too much air (overinflation),
you can get the following:
0 Unusual wear
0 Bad handling
0 Rough ride
0 Needless damage from road hazards.
When
to Check
Check your tires once a month or more.
Also, check the
tire pressure
of the spare tire.
Haw to Check
Use a
good quality pocket-type gage to check tire
pressure.
You can’t tell if yom tires are properly inflated
simply
by looking at them. Radial tires may look
properly inflated even
when they’re underinflated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and moisture.
