spare wheel Oldsmobile Bravada 2003 Owner's Manuals

Inflation -- Tire Pressure
The Certificationnire label, which is on the driver’s door
edge, above the door latch, 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 more than
1 mile (1.6 km).
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
0 Bad fuel economy
If your tires have too much air (overinflation), you
can get the following:
0 Unusual wear
0 Bad handling
0 Rough ride
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.
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell if your 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.
Tire Inspection and Rotation
Tires should be rotated every 7,500 miles (12 500 km).
Any time you notice unusual wear, rotate your tires
as soon as possible and check wheel alignment.
Also
check for damaged tires or wheels. See When It Is Time
for New Tires
on page 5-55 and Wheel Replacement
on page 5-58 for more information.
Make sure the spare tire
is stored securely. Push, pull,
and then try
to rotate or turn the tire. If it moves,
use the wheel wrench to tighten the cable. See
Changing a Flat Tire on page 5-62.

The tools you'll be using include the wheel wrench (A),
tire blocks (B), extension (socket end) (C), handle
(jack end)
(D), and jack (E).
The following instructions explain how to remove the
spare tire mounted underneath your vehicle.
Notice: Never remove or restow a tire from/to a
storage position under the vehicle while the vehicle
is supported by a jack. Always tighten the tire
fully against the underside
of the vehicle when
restowing.
f
1. To remove the underbody-mounted spare, insert
the socket end of the extension on a
45" angle
downward into the hoist drive shaft hole. This will
be exposed when the rear gate is open and is
just above the rear bumper. Be sure the socket end
of the extension connects into the hoist shaft.
5-64

2. Turn the wheel wrench counterclockwise to lower
the spare tire. Keep turning the wheel wrench until
the spare tire can be pulled out from under the
vehicle.
If the spare tire does not lower to the ground, the
secondary latch is engaged causing the tire
not to lower. See “Secondary Latch System” later in
this section.
When the tire has been completely lowered, tilt the
retainer at the end of the cable and pull it through
the wheel opening. Pull the tire out from under
the vehicle.
Notice:
To help avoid vehicle damage, do not drive
the vehicle before the cable is restored.
3. Put the spare tire near the flat tire.
4. Position the chisel end of
your wheel wrench in the
notch of the center
cap and pry
off the
center cap.
See “Removing the Flat Tire and Installing the Spare
Tire” later in this section to continue changing the flat tire.

1. Check under the vehicle
to see
if the cable is
visible.
2. If it is not visible, proceed to Step 6.
If visible, first try to tighten the cable by turning the
wheel wrench clockwise until you hear two clicks
or feel it skip twice. You cannot overtighten
the cable.
3. Loosen the cable by turning the wheel wrench
counterclockwise three or four turns.
4. Repeat this procedure at least two times.
If the spare tire lowers to the ground, continue with

approximately
6 inches (15 cm) of cable is exposed.
5. Turn the wrench counterclockwise until
6. Attach the jack handle, extension and the wheel
wrench to the jack and place it under the vehicle
towards the front of the rear bumper. Position
the center lift point of the jack under the center of
the spare tire.
7. Turn the wrench clockwise to raise the jack until it
lifts the end fitting.
8. Continue raising the jack until the spare tire stops
moving upward and is held firmly in place. The
secondary latch has released and the spare tire is
balancing on the jack.

9.
10. Lower the jack by turning the wheel wrench
counterclockwise. Keep lowering the jack until the
spare tire slides
off the jack or is hanging by
the cable.
Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to push
against the spare while firmly pulling the jack out
from under the spare tire with the other hand.
If the spare tire is hanging from the cable, insert the
jack handle, extension and wheel wrench into the
hoist shaft hole in the bumper, on an angle, and turn
the wheel wrench counterclockwise
to lower the
spare the rest of the way.
11. Tilt the retainer at the end of the cable and pull it
through the wheel opening. Pull the tire out from
under the vehicle.
12. If the cable is hanging under the vehicle, turn the
wheel wrench in the hoist shaft hole in the bumper
clockwise to raise the cable back up.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or flat tire using
the hoist assembly until it has been repaired or replaced.

Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could

In a sudden stop or collision,
loose equipment could strike someone. Store
all these in the proper place.

and suddenly fall from your vehicle. If this
happened when your vehicle was being driven,
the tire might contact a person or another
vehicle, causing injury and, of course, damage
to itself as well. Be sure the underbody-
mounted spare tire
is stored with its valve
stem pointing up.
Notice: An aluminum wheel with a flat tire should
always be stored under the vehicle with the hoist. However, storing
it that way for an extended
period could damage the wheel. To avoid this,
always stow the wheel properly with the valve stem
pointing up and have the wheel repaired as soon
as possible.
Follow this diagram to store the underbody-mounted
spare.

5. Make sure the tire is stored securely. Push, pull,
and then try to rotate or turn the tire. If the tire
moves, use the wheel wrench to tighten the cable.

proper location under the rear seat of the vehicle.
Roll up the instruction label and return it to the slot in
the tool kit.
Return the rear seat to its proper position.

At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag
system does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace
blade inserts that appear worn or damaged or that
streak or miss areas of the windshield.
Also see
Cleaning the Outside of Your Vehicle on page 5-80.
Spare Tire Check
At least twice a year, after the monthly inflation check of
the spare tire determines that the spare is inflated
to
the correct tire inflation pressure, make sure that
the spare tire is stored securely. Push, pull, and then try
to rotate or turn the tire. If it moves, use the wheel
wrenchhatchet
to tighten the cable. See Changing a Flat
Tire on page
5-62.
Engine Air Cleaner Filter Restriction
Indicator Check
Your vehicle may be equipped with an engine air
cleaner filter restriction indicator located on the air
cleaner in the engine compartment. The indicator lets
you know when the air cleaner filter is dirty and needs
to
be changed. Check the indicator at least twice a year
or when your engine oil is changed, whichever
occurs first. See
Engine Air Cleaner/Fi/fer on page 5-18
for more information. Inspect your air cleaner filter
restriction indicator more often
if the vehicle is used in
dusty areas or under
off road conditions.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be required. See
Part D: Recommended Fluids and
Lubricants on page
6-17.
Automatic Transmission Check
Check the transmission fluid level; add if needed. See
Automatic Transmission Fluid on page 5-20. A fluid loss
may indicate a problem. Check the system and repair
if needed.
