2004 Oldsmobile Silhouette lock

3. To remove the compact spare tire from the cable,
tilt the retainer at the end of the cable so it can be
pulled up through the wheel opening.
4. If your vehicle is an AWD vehicle, after removing
the compact spare tire, turn the wrench clockwise
to raise the cable back up.On an AWD vehicle, you can not store a full-size
tire under the vehicle. It should be stowed inside
the vehicle by the cable provided. See ªStoring the
Flat Tire on an All-Wheel-Drive Vehicleº later in
this section.
If you have a front-wheel-drive vehicle, the hoist is
used to store a full-size or a ¯at road tire under
the vehicle. See ªStoring the Spare Tire and Toolsº
and ªStoring the Flat Tire on a Front-Wheel Drive
Vehicleº later in this section.
If the compact spare tire will not lower, check under the
vehicle to see if the tire is hanging loose and the
cable end and spring under the wheel plate are missing.
If so, the secondary latch system is engaged. See
ªSecondary Latch Systemº later in this section.
To continue changing the ¯at tire see ªRemoving the Flat
Tire and Installing the Spare Tireº later in this section.

1. Place the jack under the vehicle, ahead of the rear
bumper. Position the center lift point of the jack
under the center of the compact spare tire.
2. Turn the folding wrench clockwise to raise the jack
until it lifts the secondary latch device under the
wheel plate.
3. Keep raising the jack until the compact spare tire
stops moving upward and is held ®rmly in place,
this lets you know that the secondary latch
has released.4. Lower the jack by turning the folding wrench
counterclockwise. Keep lowering the jack until the
compact spare tire is resting on the folding wrench.
5. Grasp the compact spare tire with both hands and
pull it out from under the vehicle.
6. Reach under the vehicle and remove the folding
wrench and jack.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or ¯at tire using
the hoist assembly until it has been repaired or replaced.

Removing the Wheel Covers
If the wheel has a center cap, use the handle of the
folding wrench to pry it off. Then, with the other end of
the folding wrench, loosen the nuts.
If your vehicle has the plastic bolt-on wheel covers,
loosen the bolts completely using the folding wrench,
and remove the wheel cover.
Removing the Flat Tire and Installing
the Spare Tire
1. Loosen the wheel
nuts Ð but do not
remove them Ð using
the folding wrench.
Turn the handle about
180 degrees, then
¯ip the handle back to
the starting position.
This avoids taking
the wrench off the
lug nut for each turn.
For wheels with a wheel lock key, use the wheel
lock key between the lock nut and folding wrench.
The key is supplied in the front passenger door
pocket.
Notice:If your vehicle has wheel locks and you
use an impact wrench to remove the wheel
nuts, you could damage the lock nut or wheel lock
key. Do not use an impact wrench to remove
the wheel nuts if your vehicle has wheel locks.

3. Attach the folding
wrench to the jack,
and turn the wrench
clockwise to raise
the jack head a few
inches.
4. Raise the vehicle by turning the folding wrench
clockwise in the jack. Raise the vehicle far enough
off the ground so there is enough room for the
compact spare tire to ®t under the wheel well.
5. Remove all the wheel nuts and take off the ¯at tire.
6. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
the places where the wheel attaches to the
vehicle. In an emergency, you can use a cloth
or a paper towel to do this; but be sure to use
a scraper or wire brush later, if you need to,
to get all the rust or dirt off.
{CAUTION:
Never use oil or grease on studs or nuts.
If you do, the nuts might come loose. Your
wheel could fall off, causing a serious
accident.

7. Install the compact spare tire and put the wheel
nuts back on with the rounded end of the nuts
toward the wheel. Tighten each nut by hand until
the wheel is held against the hub.
8. Lower the vehicle by attaching the folding wheel
wrench to the jack and turning the wrench
counterclockwise. Lower the jack completely.9. Tighten the wheel nuts
®rmly in a crisscross
sequence, as shown.
{CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to come loose
and even come off. This could lead to an
accident. Be sure to use the correct wheel
nuts. If you have to replace them, be sure to
get new GM original equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to the
proper torque speci®cation. See ªCapacities
and Speci®cationsº in the Index for wheel nut
torque speci®cation.

Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker in the instrument panel fuse panel. An electrical
overload will cause the lamps to go on and off, or in
some cases to remain off. If this happens, have
your headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due
to heavy snow, etc., the wiper will stop until the
motor cools. If the overload is caused by some electrical
problem, be sure to get it ®xed.
Power Windows and Other Power
Options
Circuit breakers in the instrument panel fuse panel
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 ®xed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers,
and fusible thermal links.
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 do not have
a spare fuse, you can borrow one that has the same
amperage or use one of the spare fuses in the
underhood fuse block. Just pick some feature of your
vehicle that you can get along without Ð like the radio or
cigarette lighter Ð and use its fuse, if it is the right
amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle, the instrument
panel fuse block and the underhood fuse block.

Instrument Panel Fuse Block
The instrument panel
fuse block is located to
the right of the glove
box on the end of the
instrument panel.
Pull the door open to access the instrument panel
fuse block.
