Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for
wear or cracking. SeeScheduled Maintenance
on page 396for more information on wiper blade
inspection.Replacement blades come in different types and
are removed in different ways. For proper type and
length, seeNormal Maintenance Replacement
Parts on page 408. Here is how to remove
the wiper blades:
1. Pull the windshield wiper arm away from the
windshield.
2. Push the release lever and slide the wiper
assembly toward the driver’s side of the
vehicle.
3. Install a new blade by reversing Steps 1 and 2.

The purpose of regular rotation is to achieve
more uniform wear for all tires on the vehicle. The
rst rotation is the most important. SeeScheduled
Maintenance on page 396.
When rotating your tires, always use the correct
rotation pattern shown here.
Do not include the compact spare tire in your tire
rotation.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the
Tire and Loading Information label.Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 390.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When
you change a wheel, remove any rust or
dirt from 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 needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 358.

If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your vehicle’s
tires properly. If air goes out of a tire, it is
much more likely to leak out slowly. But if you
should ever have a blowout, here are a few tips
about what to expect and what to do:
If a front tire fails, the at tire will create a drag
that pulls the vehicle toward that side. Take
your foot off the accelerator pedal and grip the
steering wheel rmly. Steer to maintain lane
position, and then gently brake to a stop well
out of the traffic lane.
A rear blowout, particularly on a curve, acts much
like a skid and may require the same correction you
would use in a skid. In any rear blowout remove
your foot from the accelerator pedal. Get the vehicle
under control by steering the way you want the
vehicle to go. It may be very bumpy and noisy,
but you can still steer. Gently brake to a stop,
well off the road if possible.{CAUTION:
Lifting a vehicle and getting under it to
do maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a
at tire. If it is used for anything else, you
or others could be badly injured or killed
if the vehicle slips off the jack. Use the
jack provided with your vehicle only for
changing a at tire.
If a tire goes at, the next part shows how to
use the jacking equipment to change a at
tire safely.
Changing a Flat Tire
If a tire goes at, avoid further tire and wheel
damage by driving slowly to a level place.
Turn on your hazard warning ashers.

{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel
nuts become loose after time. The wheel
could come off and cause an accident.
When changing a wheel, remove any rust
or dirt from the places where the wheel
attaches to the vehicle. In an emergency,
a cloth or a paper towel can be used to do
this; but be sure to use a scraper or wire
brush later, if needed, to get all the rust or
dirt off.11. Remove any rust or
dirt from the wheel
bolts, mounting
surfaces, and
spare wheel.
367

12. Place the compact spare tire on the
wheel-mounting surface.
{CAUTION:
Never use oil or grease on studs or nuts.
Because the nuts might come loose.
The vehicle’s wheel could fall off, causing
a serious accident.
13. Reinstall the wheel nuts with the rounded end
of the nuts toward the wheel. Tighten each nut
by hand until the wheel is held against the hub.
14. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.
{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 specication. See
Capacities and Specifications on page 390
for wheel nut torque specication.

the sleeve into the existing spare tire
hold-down bolt.
3. If your vehicle has aluminum wheels, rst
remove the center cap with your hand or
the wheel wrench.
4. Place the at tire face down into the spare tire
tub. Avoid scraping the aluminum wheel, if the
vehicle has one, on the hold-down bolt.
5. Re-attach the wheel wrench to the jack.
6. Place the jack into the center of the at tire,
being careful not to scratch the inside of

7. Place the smaller jack hold-down nut (base
models only) in a safe place for use when
you put the compact spare tire back into
the trunk.
8. Remove the plastic sleeve from the stow bolt
extension rod. Secure the jack and road
wheel using the larger plastic retainer.
The compact spare tire is for temporary use only.
Replace the compact spare with a full-size tire
as soon as possible.
Compact Spare Tire
Although the compact spare tire was fully inated
when the vehicle was new, it can lose air after
a time. Check the ination pressure regularly.
It should be 60 psi (420 kPa).
After installing the compact spare on the vehicle,
stop as soon as possible and make sure the spare
tire is correctly inated. The compact spare is made
to perform well at speeds up to 65 mph (105 km/h)
for distances up to 3,000 miles (5 000 km), so you
can nish your trip and have the full-size tire
repaired or replaced at your convenience.Of course, it is best to replace the spare with a
full-size tire as soon as possible. The spare tire
will last longer and be in good shape in case it is
needed again.
Notice:When the compact spare is installed,
do not take your vehicle through an automatic
car wash with guide rails. The compact spare
can get caught on the rails. That can damage
the tire and wheel, and maybe other parts of
your vehicle.
Do not use the compact spare on other vehicles.
And do not mix the compact spare tire or
wheel with other wheels or tires. They will not t.
Keep the spare tire and its wheel together.
Notice:Tire chains will not t your compact
spare. Using them can damage your vehicle
and can damage the chains too. Do not use
tire chains on your compact spare.

Do not clean your vehicle using the following
cleaners or techniques:
Never use a knife or any other sharp object
to remove a soil from any interior surface.
Never use a stiff brush. It can cause damage
to your vehicle’s interior surfaces.
Never apply heavy pressure or rub
aggressively with a cleaning cloth. Use of
heavy pressure can damage your interior
and does not improve the effectiveness of
soil removal.
Use only mild, neutral-pH soaps. Avoid
laundry detergents or dishwashing soaps with
degreasers. Using too much soap will leave a
residue that leaves streaks and attracts dirt.
For liquid cleaners, about 20 drops per gallon
(3.78 L) of water is a good guide.
Do not heavily saturate your upholstery while
cleaning.
Damage to your vehicle’s interior may result
from the use of many organic solvents such as
naptha, alcohol, etc.
Fabric/Carpet
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only
be used on oor carpet and carpeted oor mats.
For soils, always try to remove them rst with plain
water or club soda. Before cleaning, gently remove
as much of the soil as possible using one of the
following techniques:
For liquids: gently blot the remaining soil with a
paper towel. Allow the soil to absorb into the
paper towel until no more can be removed.
For solid dry soils: remove as much as possible
and then vacuum.
374

To clean, use the following instructions:
1. Saturate a lint-free, clean white cloth with
water or club soda.
2. Wring the cloth to remove excess moisture.
3. Start on the outside edge of the soil and gently
rub toward the center. Continue cleaning,
using a clean area of the cloth each time it
becomes soiled.
4. Continue to gently rub the soiled area until the
cleaning cloth remains clean.
5. If the soil is not completely removed, use a
mild soap solution and repeat the cleaning
process that was used with plain water.
If any of the soil remains, a commercial fabric
cleaner or spot lifter may be necessary. When a
commercial upholstery cleaner or spot lifter is to be
used, test a small hidden area for colorfastness
rst. If the locally cleaned area gives any
impression that a ring formation may result,
clean the entire surface.
After the cleaning process has been completed,
a paper towel can be used to blot excess moisture
from the fabric or carpet.Leather
A soft cloth dampened with water may be used
to remove dust. If a more thorough cleaning is
necessary, a soft cloth dampened with a mild
soap solution can be used. Allow the leather to
dry naturally. Do not use heat to dry. Never use
steam to clean leather. Never use spot lifters or
spot removers on leather. Many commercial leather
cleaners and coatings that are sold to preserve
and protect leather may permanently change the
appearance and feel of your leather and are not
recommended. Do not use silicone or wax-based
products, or those containing organic solvents to
clean your vehicle’s interior because they can
alter the appearance by increasing the gloss in a
non-uniform manner. Never use shoe polish on
your leather.
