Brake Wear
Your vehicle has front disc brakes and rear drum
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 can 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 the brakes will not 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 can cause a
brake squeal when the brakes are rst applied
or lightly applied. This does not mean something
is wrong with the 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
specications.
Rear drum brakes do not have wear indicators,
but if you ever hear a rear brake rubbing
noise, have the rear brake linings inspected
immediately. Also, the rear brake drums should be
removed and inspected each time the tires are
removed for rotation or changing. When you have
the front brake pads replaced, have the rear
brakes inspected, too.
Brake linings should always be replaced as
complete axle sets.
SeeBrake System Inspection on page 393.

1. Check the other vehicle. It must have a
12-volt battery with a negative ground system.
Notice:If the other vehicle’s system is not a
12-volt system with a negative ground,
both vehicles can be damaged. Only use
vehicles with 12-volt systems with negative
grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper
cables can reach, but be sure the vehicles are
not touching each other. If they are, it could
cause a ground connection you do not
want. You would not be able to start your
vehicle, and the bad grounding could damage
the electrical systems.
To avoid the possibility of the vehicles rolling,
set the parking brake rmly on both vehicles
involved in the jump start procedure. Put
an automatic transaxle in PARK (P) or
a manual transaxle in NEUTRAL before
setting the parking brake.Notice:If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The repairs
would not be covered by your warranty.
Always turn off your radio and other
accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles.
Unplug unnecessary accessories plugged into
the cigarette lighter. Turn off the radio and
all lamps that are not needed. This will avoid
sparks and help save both batteries. And
it could save the radio!

4. Open the hoods and locate the batteries. Find
the positive (+) and negative (−) terminal
locations on each vehicle. SeeEngine
Compartment Overview on page 282for more
information on location.
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
{CAUTION:
Using a match near a battery can cause
battery gas to explode. People have been
hurt doing this, and some have been
blinded. Use a ashlight if you need
more light.
Be sure the battery has enough water.
You do not need to add water to the
battery installed in your new vehicle. But
if a battery has ller caps, be sure the
right amount of uid is there. If it is low,
add water to take care of that rst. If you
don’t, explosive gas could be present.
Battery uid contains acid that can burn
you. Do not get it on you. If you
accidentally get it in your eyes or on your
skin, ush the place with water and get
medical help immediately.

This light, on the
instrument panel cluster,
comes on when the
tire pressure monitoring
system detects a
low-tire condition.
This light also comes on for a few seconds and
then go off when you turn the ignition to ON. This
indicates that the TPMS is functioning properly.
If the low-tire pressure warning light comes
on while driving your vehicle, the system may
have detected a low-tire condition. You need to
stop as soon as possible and check your tires
for damage. If a tire is at, seeIf a Tire Goes Flat
on page 342andChanging a Flat Tire on
page 343. Also check the tire pressure in all four
tires, and set them to the specied level shown
on the Tire and Loading Information label.SeeInation - Tire Pressure on page 329and
Loading Your Vehicle on page 253for additional
information.
Note:The tire pressure monitoring system on your
vehicle warns you when one of the tires is
signicantly under-inated and when some
combinations of the tires are signicantly
under-inated. However, there are other
combinations of signicantly under-inated tires for
which the tire pressure monitoring system might not
give a warning. These other combinations are
relatively common, accounting for approximately
half the instances in which vehicles have
signicantly under-inated tires. For example, the
system might not warn you when both tires on the
same side or on the same axle of your vehicle are
signicantly under-inated. It is particularly
important, therefore, to check the tire pressure in all
of the tires regularly and maintain proper pressure.
In order for the tire pressure monitoring system to
work properly you need to reset (initialize) the
tire pressure monitoring system. Any time
you check and/or adjust a tire’s pressure, repair or
replace a tire or wheel, or rotate the tires the
tire pressure monitor system needs to be reset.
331

Do not reset (initialize) the system without rst
correcting the cause of the low-tire condition. If the
system is reset when the tire pressures are
incorrect, the system will not function properly and
might not alert you when a tire is low.
To reset (initialize) the system:
1. Park the vehicle at a safe place and apply the
parking brake. Turn the engine off.
2. Turn the ignition to ON with the engine off.
3. If the low-tire
pressure warning
light is on, push
the SET (reset)
button for a
few seconds.
The reset button is on the instrument panel to
the left of the steering wheel. The low-tire
warning light should go off.4. Press and hold the SET (reset) button until
the low-tire warning light comes on and
ashes on/off three times. The tire pressure
warning reset button starts the reset
(initialization) process.
If the low-tire pressure warning light does not
ash while you hold the reset button, the
system might be malfunctioning and needs
service. See your GM dealer for service.
The system completes the reset (initialization)
process after driving at vehicle speeds of at least
19 mph (30 km/h) to 62 mph (100 km/h) for
more than one hour. Do not push the SET (reset)
button while driving. If you do the initialization
process is cancelled. The initialization process can
take up to approximately one hour of driving
under the following conditions:
The vehicle speed is between 31 mph
(50 km/h) and 62 mph (100 km/h).
The roads are dry, smooth, and straight.
The number of passengers is one or
two (including the driver).
332

The low-tire pressure warning light may not come
on even if the tire ination pressure is low, or it
could come on when the tire ination pressure is
set correctly under the following circumstances:
A compact spare tire, snow tires, or tire chains
are installed on your vehicle.
The tires are over-inated, or the tire ination
pressure suddenly drops due to a tire bursting
or other causes.
The vehicle is driven on a slippery road
surface such as rough or frozen roads.
The vehicle speed is less than
19 mph (30 km/h), and the driving duration is
less than ve minutes.
The tires are made by a different manufacturer
or differ in tread pattern than the original
equipment tires.
Rapid acceleration/deceleration or multiple
consecutive sharp turns.
Towing a trailer.
The vehicle is loaded over the limit or not
balanced properly.
The initialization (reset) procedure was not
performed correctly after replacing or
rotating tires or wheels.
The outside temperature is below 32°F (0°C)
or above 104°F (40°C).
Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 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.
SeeWhen It Is Time for New Tires on page 335
andWheel Replacement on page 340for
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 376for scheduled rotation intervals.
