2003 Oldsmobile Bravada fuel cap

If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
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 recently put fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. See
Filling Your Tank on page 5-7. The
diagnostic system can determine
if the fuel cap has
been left
off or improperly installed. A loose or missing
fuel cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light
off.
Did you just drive through a deep puddle of water? Have
you recently changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-5. 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 one or more of these conditions,
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.
If
so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.

Gate Ajar Light
‘1
United States Canada
If this light comes on, your liftgate or liftglass is ajar. Try
closing the liftgate or liftglass again. Never drive with
the liftgate or liftglass even partially open.
Fuel Gage
a
When the ignition is on, the fuel gage tells you about
how much fuel you have remaining.
Here are four 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 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
The gage doesn’t go back to empty when you turn
speed up.
off the
ignition.
Low Fuel Warning Light
The light next to the fuel gage will come on briefly when
you are starting the engine.
This light comes on when the fuel tank is low on fuel.
To turn it
off, add fuel to the fuel tank. See Fuel on
page 5-5.

Towing Loading Your Vehicle
Towing
Your Vehicle
Consult your dealer or a professional towing service if
you need to have your disabled vehicle towed. See
Roadside Assistance Program on page 7-5.
If you want to tow your vehicle behind another vehicle
for recreational purposes (such as behind a motorhome),
see “Recreational Vehicle Towing” following.
Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle
- such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as “dinghy towing” (towing your vehicle
with all four wheels on the ground) and “dolly towing”
(towing your vehicle with two wheels on the ground and
two wheels up on a device known as a “dolly”).
Your vehicle was not designed to be towed with any
OJ
its wheels on the ground. If your vehicle must be
towed, see “Towing Your Vehicle” earlier in this section. The
Certificationflire label is found on the driver’s door
edge, above the door latch. The label shows the
size of your original tires and the inflation pressures
needed to obtain the gross weight capacity of your
vehicle. This is called the Gross Vehicle Weight Rating (GVWR). The GVWR includes the weight of the
vehicle, all occupants, fuel, cargo and trailer tongue
weight,
if pulling a trailer.

Towing a Trailer
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
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 dealer for
important information about towing a trailer with
your vehicle. Additional rear axle maintenance
is required for a vehicle used to tow a trailer. See
“Scheduled Maintenance Services’’
in the Index.
To identify the trailering capacity of your vehicle,
you should read the information in “Weight of the Trailer’’
that appears later in this section.
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 part. In
it are many time-testea,
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.

Filling Your Tank
II
Fuel vapor is highly flammable. It burns
violently, and that can cause very bad injuries. Don’t smoke if you’re near fuel or refueling
your vehicle. Keep sparks, flames and smoking
materials away from fuel.
The fuel cap is located behind a hinged door on the
driver’s side
of your vehicle.
5-7

.-
While refueling, hang the fuel cap by the tether using
the hook located on the inside of the filler door.
To remove the fuel cap, turn it slowly to the left
(counterclockwise). The fuel cap has
a spring in it. If
you let go of the cap too soon, it will spring back to the
right. If you gel ,Jel on yoursel,.
,nd then some.,,,ng
ignites
it, you could be badly burned. Fuel can
spray out on you
if you open the fuel cap too
quickly. This spray can happen
if your tank is
nearly full, and is more likely in hot weather.
Open the fuel
cap slowly and wait for any
“hiss” noise to stop. Then unscrew the cap all
the way.
Be careful not to spill fuel. Clean fuel from painted
surfaces
as soon as possible. See Cleaning the Outside
of Your Vehicle on page 5-80. When filling the tank
do not overfill by squeezing in much more fuel after the
pump shuts
off.
5-8

When you put the fuel cap back on, turn it to the right
(clockwise) until you hear a clicking sound. 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 into the
atmosphere. See
Malfunction lndicator Lamp on
page 3-35.
Notice: If you need a new fuel 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 properly.
This may cause your malfunction indicator lamp to
light and may damage your fuel tank and emissions
system. See “Malfunction lndicator Lamp”
in the
Index.
Filling a Portable Fuel Container
NeveL ,,I1 a portable f,,l container while it is in
your vehicle. Static electricity discharge from
the container can ignite the gasoline vapor. You can be badly burned and your vehicle damaged if
this occurs. To help avoid injury to
you and others:
Dispense gasoline only into approved
containers.
Do not fill a container while it is inside a
vehicle,
in a vehicle’s trunk, pickup bed or
on any surface other than the ground.
Bring the fill nozzle in contact with the
I inside of the fill opening before operating
i the nozzle. Contact should be maintained
Don’t smoke while pumping gasoline.
until the filling
is complete.
