2006 BUICK TERRAZA Owner's Manual

{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.

The tools you will be using include the jack (A),
extension (B), and folding wrench (C).
The compact spare tire is located under the rear of the
vehicle. SeeCompact Spare Tire on page 5-86for
more information about the compact spare.

and insert the chisel end on an angle through the
hole in the rear bumper and into the hoist shaft (A).

5-73

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.
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 “Storing the Flat Tire on an
All-Wheel-Drive Vehicle” underStoring a Flat or
Spare Tire and Tools on page 5-83for more
information.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 “Storing the Flat Tire on an
Front-Wheel-Drive Vehicle” underStoring a Flat or
Spare Tire and Tools on page 5-83for 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. See
Secondary Latch System on page 5-81.
To continue changing the at tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 5-75.

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
using the folding
wrench, but do not
remove them.
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.
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.
5-75

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.
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.
A. Front Location
B. Rear Location2. 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.
Do not raise the vehicle yet.
3. 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.
5-76

{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 (A) to the jack (B), and
turn the wrench clockwise to raise the jack head
approximately 3 inches (7.6 cm).
5-77

5. 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.
6. Remove all the wheel nuts and take off the at tire.
{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.
