If there is a wheel cover, 
loosen the plastic  nut caps 
with the wheel wrench. 
They won’t come off. Then,  using the  flat end 
of the 
wheel wrench, pry  along the 
edge  of the cover until  it 
comes off.  Be careful;  the 
edges  may be sharp. Don’t 
try  to remove the cover with 
your bare hands. 
Removing  the  Flat  Tire  and  Installing  the 
Spare  Tire 
If  your vehicle  has wheel nut  caps, remove them using 
the wheel wrench. 
1. Using the wheel wrench, loosen all the wheel nuts. 
Don’t remove them  yet. 
2. Turn the jack  handle  clockwise  to  raise  the jack  lift 
head 
a few  inches.

& CAUTION: 
- - 
Raising  your  vehicle  with  the jack i 
positioned can damage  the  vehicle  and even  make 
the  vehicle  fall.  To  help  avoid  personal  injury and 
vehicle  damage,  be  sure 
to fit the jack  lift  head  into 
the  proper  location  before  raising  the vehicle. 
3. Raise the  vehicle by turning  the jack  handle 
clockwise. Raise the  vehicle  far enough off the 
ground  for the  spare  tire  to  fit  under the vehicle. 
Remove  all wheel nuts and take  off the  flat  tire. 
4. Remove any rust or dirt 
from  the wheel  bolts, 
mounting surfaces 
and 
spare  wheel. 
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.

7. Tighten the wheel nuts 
firmly  in 
a crisscross 
sequence as shown. 
Incorrect  wheel nuts or improperly  tightened 
wheel  nuts can cause  the wheel  to become  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 
100 Ib-ft (140 Nom). ’ 
NOTICE: 
Improperly tightened  wheel nuts can lead to 
brake  pulsation  and  rotor  damage. 
To avoid 
expensive  brake  repairs,  evenly tighten the  wheeI 
nuts  in the  proper  sequence  and  to the proper 
torque  specification. 
Don’t try to  put  the wheel  cover on your compact 
spare tire. 
It won’t fit. Store  the  wheel cover in the 
trunk until  you have th’e  flat tire repaired  or replaced. 
NOTICE: 
Wheel  covers  won’t fit on your compact spare. If 
you try to put  a wheel  cover on  your compact 
spare,  you could  damage the cover  or the spare.

Storing the  Flat Tire and Tools 
Storing a jack, a tire  or  other  equipment  in  the 
passenger  compartment 
of the  vehicle  could 
cause 
injury. In  a  sudden  stop  or  collision,  loose 
equipment  could  strike  someone.  Store 
all these 
in  the  proper  place. 
After you’ve put the compact  spare tire on your vehicle, 
you’ll  need to  store  the  flat  tire  in your trunk. Use the 
following procedure 
to secure the flat  tire  in  the trunk.  When storing a full-size  tire you must use  the  extension 
to help avoid wheel  surface damage. Use extension  and 
protector/guide located  in  foam holder. 
To store a 
full-size  tire, place  tire  valve  stem  facing  down then 
remove protectivelguide and  attach  retainer securely. 
When reinstalling compact  spare put protective/guide 
back  in foam  holder.  Store the cover 
as far forward 
as possible.

Compact Spare Tire 
Although the compact spare tire was fully inflated 
when  your vehicle 
was new, it can lose air after  a time. 
Check 
the inflation pressure regularly.  It should be 
60 psi (420 Ha). 
After  installing  the compact spare on your vehicle,  you 
should  stop  as  soon 
as possible  and make sure your  spare 
tire  is  correctly  inflated. 
The compact  spare is made to 
perform  well 
at speeds up to 65 rnph (105 kdh) for 
distances  up to 
3,000 miles (5 000 krn), so YOU can finish 
your trip and have  your  full-size  tire  repaired  or replaced 
where 
you want. You must  calibrate the Tire Pressure 
Monitor  after  installing 
or removing  the compact spare. 
See “Driver  Information  Center - Controls  and Displays” 
in 
the Index. Of course,  it’s best to  replace  your spare 
with a full-size tire as soon as you can. Your spare 
will  last  longer  and be in  good  shape  in  case you need 
it again. 
NOTICE: 
When the compact spare is installed, don’t take 
your  vehicle  through an automatic  vehicle  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. 
Don’t use your compact spare on other vehicles. 
And don’t mix your compact spare tire or wheel with 
other wheels or tires. They won’t fit. Keep your spare 
tire and  its wheel together. 
NOTICE: 
Tire chains  won’t fit your compact spare.  Using 
them  can damage  your  vehicle 
and can damage 
the ‘chains too. Don’t use tire chains on your 
compact spare.

To calibrate the system: 
1. Turn the ignition switch  to ON. 
2. The CALIBRATE TIRE PRESS button is under the 
instrument panel, to the right  of the steering column. 
Press  and hold the button for about three seconds. 
The 
CHECK TIRE PRFSS light will flash  three 
times  and go  out. 
If the light doesn’t go out after  you 
press  the 
CALIBRATE TIRE PRESS button,  see 
your  dealer for service. 
3. The system completes the calibration process during 
driving. During the first 
10 to 20 miles (15 to 30 km) 
of  driving,  the system  will not alert you if a tire  is 
low  or high.  After 
20 to 80 miles (30 to 125 km), the 
system will  only alert 
you about pressure differences 
of 
12 psi (85 kPa) or more.  After 80 miles (125 km) 
of driving, the system will alert you if a tire  is 8 psi 
(55 Pa) different from the other  three tires. 
Tire Inspection and Rotation 
Tires  should  be rotated every 6,000 to 8,000 miles 
(10 000 to 13 000 km). Any time  you notice unusual 
wear, rotate your tires  as soon  as possible and check 
wheel alignment. Also  check  for damaged tires or 
wheels.  See “When 
It’s Time  for New Tires” and 
“Wheel Replacement” later  in this section for 
more  information.  The 
purpose 
of regular rotation  is to  achieve more 
uniform wear for all tires on the vehicle.  The  first 
rotation  is the most important.  See “Scheduled 
Maintenance Services” in  the Index  for scheduled 
rotation intervals. 
When  rotating your tires, always  use 
the correct rotation 
pattern shown here. 
Don’t  include  the  compact spare tire in your tire  rotation.

g New Tires 
To find out what kind and  size of tires you need, look at 
the Tire-Loading Information label. 
The tires installed  on your  vehicle  when it was  new  had 
a Tire Performance  Criteria Specification (TPC  Spec) 
number  on  each  tire’s sidewall. When 
you get new  tires, 
get ones with that  sarne TPC  Spec  number. That way 
your  vehicle will  continue  to have tires that  are designed 
to  give proper  endurance, handling, speed rating, 
traction,  ride and other  things during normal  service 
on 
your vehicle. If your tires  have an all-season tread 
design, the TPC number will be followed by an “MS” 
(for mud  and snow). 
If  you ever  replace your tires with those not having a 
TPC  Spec  number, make  sure they  are the same  size, 
load range, speed rating and construction  type (bias, 
bias-belted  or  radial) as your  original  tires. Reset Tire 
Inflation Monitor 
(TIM). 
I 
Mixing  tires  could  cause  you to lose control while 
driving. 
If you  mix  tires of different  sizes or  types 
(radial  and  bias-belted 
tires), the  vehicle  may  not 
handle  properly,  and  you could  have 
a crash. 
Using tires of different  sizes  may  also  cause 
damage  to  your  vehicle. 
Be sure  to  use  the  same 
size  and  type  tires 
on all wheels. 
It’s all  right to drive with your  compact  spare, 
though. It was developed  for  use on your vehicle.
