2003 Oldsmobile Bravada window

Driving with a ‘railer
I..
If you have a rear-most window open and you
pull a trailer with your vehicle, carbon
monoxide
(CO) could come into your vehicle.
You can’t see or smell CO.
It can cause
unconsciousness
or death. See “Engine
Exhaust” in the Index.
To maximize your safety
when towing a trailer:
Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
Keep the rear-most windows closed.
If exhaust does come into your vehicle
through a window
in the rear or another
opening, drive with your front, main heating
or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle.
Do not use
the climate control setting for maximum air because
it only recirculates the air inside
your vehicle. See “Climate Controls”
in the
Index. Towing a trailer requires a certain
amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you
start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment.
If the trailer has
electric brakes,
start your vehicle and trailer moving and
then apply the trailer brake controller by hand
to be
sure the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally
to be sure that the
load is secure, and that the lamps and any trailer
brakes are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as
you would when driving your vehicle without a trailer.
This can help you avoid situations that require
heavy braking and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer, you’ll need
to go much farther beyond the
passed vehicle before you can return
to your lane.

1-1 Your vehicle may have this
feature. The engine air cleanedfilter assembly has
an indicator that lets
you know when the air
filter is dirty and needs to
be serviced. The
indicator is located on the
engine air cleaner/filter
air duct.
The service window

shows the amount of engine air cieanedfilter life used.
When both service window
(A) and service window
(B) turn orange, replace the engine air cleanedfilter
After changing the engine air cleaner/filter, press
the button on top of the indicator to reset it.
For vehicles without an indicator, refer
to the
maintenance schedule to determine when
to replace the

If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. In heavy traffic, let the engine idle in neutral while
stopped.
If it is safe to do so, pull off the road, shift
to
PARK (P) or NEUTRAL (N) and let the
engine idle.
speed and open the window as necessary.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 minutes.
If the warning doesn’t come back on, you can drive
normally.
If the warning continues and you have not stopped, pull
over, stop, and park your vehicle right away.
2. Turn on your heater to full hot at the highest fan
If there’s still no sign of steam, you can push down the
accelerator until the engine speed
is about twice as
fast as normal idle speed for at least three minutes while
you’re parked.
If you still have the warning, turn off
the engine and get everyone out of the vehicle until it
cools down.
You may decide not to lift the hood but to get service
help right away.
Cooling System
When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Engine Fan
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it
cools down. The vehicle
should be parked on a level surface.

Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst into flames
if you strike a
match or get them on a hot part
of the vehicle. Some are
dangerous
if you breathe their fumes in a closed
space. When you use anything from a container to clean
your vehicle, be sure to follow the manufacturer’s
warnings and instructions. And always open your doors
or windows when you’re cleaning the inside.
Never use these to clean your vehicle:
Gasoline
0 Benzene
Naphtha
Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
Lacquer Thinner
0 Nail Polish Remover
They can all be hazardous
- some more than
others
- and they can all damage your vehicle, too. Don’t use
any of these unless this manual says you
can. In many uses, these will damage your vehicle:
Alcohol
Laundry Soap
Bleach
Reducing Agents
Cleaning the Inside of Your Vehicle
Use a vacuum cleaner often to get rid of dust and
loose dirt. Wipe vinyl, leather, plastic and painted
surfaces with a clean, damp cloth.
FabriclCarpet
Your dealer has cleaners for the cleaning of fabric and
carpet. They will clean normal spots and stains very well.
You can get
GM - approved cleaning products from
your dealer. See
GM Vehicle Care/Appearance
Materials
on page 5-83.
5-77

Interior Plastic Components
Use only a mild soap and water solution on a soft cloth
or sponge. Commercial cleaners may affect the
surface finish.
Vinyl
Use warm water and a clean cloth.
Rub with a clean, damp cloth to remove dirt. You
may have to do this more than once.
Things like tar, asphalt and shoe polish will stain if
you don’t get them off quickly. Use a clean cloth
and vinyl/leather cleaner. See your dealer for
this product.
Leather
Use a soft cloth with lukewarm water and a mild soap or
saddle soap and wipe dry with a soft cloth. Then, let
the leather dry naturally.
Do not use heat to dry.
0 For stubborn stains, use a leather cleaner. See your
dealer for this product.
Never use oils, varnishes, solvent-based or abrasive
cleaners, furniture polish or shoe polish on leather.
Soiled or stained leather should be cleaned
immediately.
If dirt is allowed to work into the finish,
it can harm the leather.
Top of the Instrument Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones
or waxes may cause annoying reflections in the
windshield and even make it difficult
to see through the
windshield under certain conditions.
Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner or a
liquid household glass cleaner will remove normal
tobacco smoke and dust films on interior glass. See
GM
Vehicle Care/Appearance Materials on page
5-83.
Notice: Don’t use abrasive cleaners on glass,
because they may cause scratches. Avoid placing
decals on the inside rear window, since they
may have to be scraped
off later. If abrasive cleaners
are used on the inside
of the rear window, an
electric defogger element may be damaged. Any
temporary license should
not be attached across the
defogger grid.

Electrical System
Add-on Electrical Equipment
Notice: Don’t add anything electrical to your
vehicle unless you check with your dealer first.
Some electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment can
keep other components from working as they
should.
Your vehicle has an air bag system. Before attempting
to add anything electrical to your vehicle, see
Servicing Your Air Bag-Equipped Vehicle on page 1-55.
Headlamps
The headlamp wiring is protected by four fuses. An
electrical overload will cause a lamp
to go on and off. If
this happens, have your headlamp wiring checked
right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a fuse.
If the motor overheats due to heavy
snow or ice, the wiper will stop until the motor cools.
If the overload is caused by some electrical problem, be
sure
to get it fixed.
Power Windows and Other Power
Options
Circuit breakers protect the power windows and other
power accessories. When the current load is
too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of fires
caused by electrical problems.
Look at the silver-colored band inside the fuse.
If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage.
Just pick some feature of your vehicle
that you can get along without
- like the radio or
cigarette lighter
- and use its fuse, if it is the correct
amperage. Replace it
as soon as you can.
