Torque Lock
If you are parking on a hill and you don't shift your
transaxle into PARK (P) properly, the weight of
the vehicle may put too much force on the parking pawl
in the transaxle. You may ®nd it difficult to pull the
shift lever out of PARK (P). This is called ªtorque lock.º
To prevent torque lock, set the parking brake and
then shift into PARK (P) properly before you leave the
driver's seat. To ®nd out how, see
Shifting Into Park (P)
on page 2-34.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to take some of
the pressure from the parking pawl in the transaxle,
so you can pull the shift lever out of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transaxle shift lock
control system. You have to fully apply your regular
brakes before you can shift from PARK (P) when
the ignition is ON. See
Automatic Transaxle Operation
on page 2-27.
If you cannot shift out of PARK (P), ease the pressure
on the shift lever. Push the shift lever all the way
into PARK (P) as you maintain brake application. Then
move the shift lever into the gear you want. If you
ever hold the pedal down but still can't shift out of
PARK (P), try the following:
1. Turn the ignition key to ACCESSORY. Open and
close the driver's door to turn off the RAP feature.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear you
want.
5. Have the vehicle ®xed as soon as you can.

Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads
are worn and new pads are needed. The sound
may come and go or be heard all the time your vehicle
is moving (except when you are pushing on the
brake pedal ®rmly).
{CAUTION:
The brake wear warning sound means that
soon your brakes won't work well. That could
lead to an accident. When you hear the brake
wear warning sound, have your vehicle
serviced.
Notice:Continuing to drive with worn-out brake
pads could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are ®rst applied or lightly
applied. This does not mean something is wrong with
your brakes.Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in
the proper sequence to GM torque speci®cations.
Brake linings should always be replaced as complete
axle sets.
See
Brake System Inspection on page 6-14.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in
pedal travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.
5-40

Tire Inspection and Rotation
Tires should be rotated every 7,500 miles (12 500 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 Is Time
for New Tires on page 5-65andWheel Replacement
on page 5-69for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The ®rst rotation
is the most important. See
Part A: Scheduled
Maintenance Services on page 6-4for 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.
After the tires have been rotated, adjust the front and
rear in¯ation pressures as shown on the Tire-Loading
Information label.
Vehicles equipped with the Tire Pressure Monitor (TPM)
system will need to have the sensors reset after a tire
rotation is performed. A special tool is needed to
reset the sensor identi®cation codes. See your dealer
for service.
Make certain that all wheel nuts are properly tightened.
See ªWheel Nut Torqueº underCapacities and
Speci®cations on page 5-101.
5-64

12. Tighten the wheel nuts
®rmly in a crisscross
sequence as shown.
13. If your vehicle is equipped with wheel nut covers,
screw them on with your ®ngers, then tighten
one-quarter turn with the wheel wrench.
{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 speci®cation. See ªCapacities
and Speci®cationsº in the Index for wheel nut
torque speci®cation.
5-80

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 speci®cation. See ªCapacities and
Speci®cationsº in the index for the wheel nut torque
speci®cation.
Don't try to put a wheel cover on your compact spare
tire. It won't ®t. Store the wheel cover and lug nut caps in
the trunk until you have the ¯at tire repaired or
replaced.
Notice:Wheel covers won't ®t 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
{CAUTION:
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 ¯at tire in your trunk.
Store the ¯at tire as far forward in the trunk as possible.
Store the jack and wheel wrench in their compartment
in the trunk. For storage, the jack must be raised
until the screw end is ¯ush with the edge of the jack.
