wheel BUICK RANDEZVOUS 2006 Workshop Manual

Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned and
balanced carefully at the factory to give you the longest
tire life and best overall performance. Adjustments to
wheel alignment and tire balancing will not be necessary
on a regular basis. However, if you notice unusual tire
wear or your vehicle pulling to one side or the other,
the alignment may need to be checked. If you notice your
vehicle vibrating when driving on a smooth road, your
tires and wheels may need to be rebalanced. See your
dealer for proper diagnosis.
Wheel Replacement
Replace any wheel that is bent, cracked or badly
rusted or corroded. If wheel nuts keep coming loose,
the wheel, wheel bolts and wheel nuts should be
replaced. If the wheel leaks air, replace it (except some
aluminum wheels, which can sometimes be repaired).
See your dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted
the same way as the one it replaces.If you need to replace any of your wheels, wheel bolts or
wheel nuts, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your vehicle.
{CAUTION:
Using the wrong replacement wheels, wheel
bolts or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts and wheel nuts for replacement.
Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance and tire or tire chain
clearance to the body and chassis.
SeeChanging a Flat Tire on page 5-70for more
information.

Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You cannot know how it has been
used or how far it has been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.
Tire Chains
{CAUTION:
Do not use tire chains. There is not enough
clearance. Tire chains used on a vehicle
without the proper amount of clearance can
cause damage to the brakes, suspension,
CAUTION: (Continued)
CAUTION: (Continued)
or other vehicle parts. The area damaged by
the tire chains could cause you to lose control
of your vehicle and you or others may be
injured in a crash.
Use another type of traction device only if
its manufacturer recommends it for use on
your vehicle and tire size combination and
road conditions. Follow that manufacturer’s
instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if it is contacting your vehicle, and
do not spin the wheels. If you do nd traction
devices that will t, install them on the
front tires for front-wheel-drive vehicles.
If your vehicle has all-wheel drive, install
traction devices on either the front tires or
all four tires, but never on the rear tires only.

Notice:If you run the accessory inator longer than
30 minutes at a time, you could damage the inator.
The repairs would not be covered by your warranty.
Run the inator for short periods of time only.
After running the accessory inator for 30 minutes, wait at
least 10 minutes before restarting the accessory inator.
To turn off the inator, do the following:
1. Press the switch and detach the hose, rst from
the inated object, then from the outlet.
2. Put the protective cap back on.
3. Place the inator kit tools in the pouch, and store
in the glove box.
To put the cover back on, line up the tabs at the back
of the cover and put it in place. Push down the tab
to secure the cover.
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 vehicle’s
hazard warning ashers. SeeHazard Warning Flashers
on page 3-6for more information.
{CAUTION:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you
or other people. You and they could be badly
injured or even killed. Find a level place to
change your tire. To help prevent the vehicle
from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
CAUTION: (Continued)
CAUTION: (Continued)
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle will not
move, you should put blocks at the front
and rear of the tire farthest away from the
one being changed. That would be the tire,
on the other side, at the opposite end of the
vehicle.

Removing the Flat Tire and
Installing the Spare Tire
1. If there is a wheel cover, loosen the plastic nut
caps with the wheel wrench. They will not come
off. Then, using the at end of the wheel wrench,
pry along the edge of the cover until it comes off.
Be careful; the edges may be sharp. Do not
try to remove the cover with your bare hands.
If your vehicle has aluminum wheels, remove the
wheel nut caps using the wheel wrench.
2. Loosen the wheel
nuts — but do not
remove them — 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. Locate the notch
(A is 3.0 inches
(7.5 cm) from the
front tire or B is
5.5 inches (14.0 cm)
from the rear tire).
The notch is located
near each wheel in
the vehicle’s body.
Notice:If you use a jack to raise the vehicle
without positioning it correctly, you could damage
your vehicle. When raising your vehicle on a
jack, avoid contact with the rear axle control arms.
Do not raise the vehicle yet. Put the compact spare
tire near you.

{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to t the
jack lift head into the proper location before
raising the vehicle.4. Attach the folding
wrench to the jack,
and turn the wrench
clockwise to raise
the jack head
3 inches (7.6 cm).
5. Raise the vehicle by turning the folding wrench
clockwise in the jack. Raise the vehicle far
enough off the ground so that there is enough room
for the spare tire to t under the wheel well.
6. Remove all the wheel nuts and take off the at tire.
5-78

{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 needed, 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. Remove any rust or
dirt from the wheel
bolts, mounting
surfaces and spare
wheel.
8. Lower the vehicle by attaching the folding wrench to
the jack and turning the wrench counterclockwise.
Lower the jack completely.
