BUICK TERRAZA 2007 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.

loosening and then removing the wing nut (D)
and bracket (C).
5. Separate the plastic pouch from the jack and
remove the jacking tools, including the folding
wrench and extension, from the pouch.
472

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 486for more information about the compact
spare.To remove the compact spare tire, do the
following:
A. Hoist Shaft
B. Hoist Assembly
C. Retainer
D. Compact
Spare TireE. Extension
(Chisel End)
F. Folding Wrench
1. Attach the folding wrench (F) to the
extension (E) and insert the chisel end on an
angle through the hole in the rear bumper
and into the hoist shaft (A).
473

2. Turn the folding wrench counterclockwise to
lower the compact spare tire (D) 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.The hoist is used to store a full-size or a at
road tire under the vehicle. SeeStoring a
Flat or Spare Tire and Tools on page 483for
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 481.
To continue changing the at tire, seeRemoving
the Flat Tire and Installing the Spare Tire on
page 474.
Removing the Flat Tire and
Installing the Spare Tire
Your vehicle may have aluminum wheels. If so, you
will see exposed stainless steel wheel nuts. Use the
wheel wrench to loosen all of the wheel nuts. Do not
remove them yet. Or, your vehicle may have steel
wheel covers. To remove the wheel covers and
wheel nut caps, loosen the plastic nut caps with the
wheel wrench in a counterclockwise direction.
474

If needed, you can nish loosening with your
ngers. The plastic nut caps will not come off. Use
the at end of the wheel wrench and pry along the
edge of the cover until it comes off. The edge of the
wheel cover could be sharp, so do not try to remove
it with your bare hands. Do not drop the cover or lay
it face down, as it could become scratched or
damaged. Once you have removed the wheel
cover, use the following procedure 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.
475

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 Location
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.
Do not raise the vehicle yet.
3. Put the compact spare tire near you.
476

{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 (A) to the jack (B),
and turn the wrench clockwise to raise the
jack head approximately 3 inches (7.6 cm).
477

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.
478

7. Remove any rust or
dirt from the wheel
bolts, mounting
surfaces and spare
wheel.
{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.8. 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.
479

9. Lower the vehicle by attaching the folding
wheel wrench to the jack and turning the
wrench 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 503
for wheel nut torque specication.
Notice:Improperly tightened wheel nuts can
lead to brake pulsation and rotor damage.
To avoid expensive brake repairs, evenly
tighten the wheel nuts in the proper sequence
and to the proper torque specication. See
Capacities and Specifications on page 503for
the wheel nut torque specication.
