BUICK TERRAZA 2005 Owner's Manual

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 5-62for more
information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been
used or how far it’s been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.
5-59

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 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 your vehicle’s wheels. If you do nd
traction devices that will t, install them on
the front tires.
Accessory Inator
Your vehicle has an accessory inator. With it, you
can inate things like air mattresses and basketballs,
and you can also use it to bring your tires up to the
proper pressure.
The accessory inator is located in the rear
compartment on the driver’s side. To access the
accessory inator, do the following:
1. Open the liftgate. SeeLiftgate on page 2-22for
more information.
2. Lift the lever to move the third row rear seatback
forward. SeeThird Row Seat on page 1-12for
more information.
3. Remove the cover by pulling the lever out.
This symbol is on the
accessory inator switch.
5-60

There may be an accessory inator kit stored in the rear
compartment on the passenger’s side. It includes a
20-foot (6 m) hose with an air pressure gage and nozzle
adapters.
{CAUTION:
Inating something too much can make it
explode, and you or others could be injured.
Be sure to read the inator instructions, and
inate any object only to its recommended
pressure.
To use your accessory inator system, do the following:
1. Turn the ignition to ACCESSORY or RUN.
2. Attach the appropriate nozzle adapter, if required,
to the end of the hose that has the pressure gage.
3. Attach that end of the hose to the object you wish
to inate.
4. Remove the protective cap covering the outlet.
5. Attach the other end of the hose to the outlet.
6. Press the accessory inator switch. The light in the
switch will come on to show the system is working.If the accessory inator system does not turn on or
the light does not come on, the fuse may be blown or
installed incorrectly. SeeFuses and Circuit Breakers
on page 5-87or see your dealer for service.
Your accessory inator will automatically shut off after
about 10 minutes. The light in the switch will blink. After
about one minute you can use the system again. Press
the switch and the indicator light will come on.
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.

If a Tire Goes Flat
It is unusual for a tire to blowout while you’re driving,
especially if you maintain your 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 your
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.
5-62

{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).
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.When your vehicle has a at tire, use the following
example as a guide to assist you in the placement of
wheel blocks.
The following information will tell you next how to use
the jack and change a tire.

5-65

2. Turn the folding wrench counterclockwise to lower
the compact spare tire to the ground. Continue to
turn the wrench so the compact spare tire can
be pulled out from under the vehicle.
3. Tilt the retainer at the end of the cable to remove
the compact spare tire, so it can be pulled up
through the wheel opening.After removing the compact spare tire, turn the
wrench clockwise to raise the cable back up. You
can not store a full-size tire under the vehicle.
It should be stowed inside the vehicle by the cable
provided. SeeStoring a Flat or Spare Tire and
Tools on page 5-74for more information.
4. Remove the compact spare tire from the cable.
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.
SeeSecondary Latch System on page 5-72.
To continue changing the at tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 5-67.

Removing the Flat Tire and
Installing the Spare Tire
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.
Once the center cap and/or wheel cover are removed,
use the following steps to remove the at tire and
install the spare tire.1. Loosen the wheel
nuts — but do not
remove them — using
the folding wrench.
Turn the handle
counterclockwise 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 equipped 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.
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.
5-67

Notice:If you position the jack under the rocker
molding and attempt to raise the vehicle, you could
break the molding and/or cause other damage to
your vehicle. Always position the jack so that when
the jack head is raised, it will t rmly in the
notch located inboard from the rocker molding.
2. Near each wheel, there is a notch (A and B) in
the vehicle’s frame, inboard of the rocker molding.
Position the jack and raise the jack head until it
ts rmly into the notch in the vehicle’s frame
nearest the at tire.3. Do not raise the vehicle yet.
4. 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.
