156 Driving and Operating
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
you steer around the obstacle while
braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You may hear the ABS
pump or motor operating and feel
the brake pedal pulsate. This is
normal.
Braking in Emergencies
ABS allows you to steer and brake
at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Brake Force Distribution
During braking while driving through
turns, the system optimizes the
distribution of force to each of the
four wheels depending on the radius
of the turn.
Parking Brake
To apply the parking brake, pull up
on the parking brake handle. It is
not necessary to press the release
button in while applying the parking
brake. If the ignition is in the ON/
RUN position, the brake system
warning light will come on. See
Brake System Warning Light093.
{Warning

Be sure the parking brake is
fully released before driving.
Failure to do so can cause
brake failure and lead to an
accident.
. Do not release the parking
brake from outside the
vehicle.
. Do not use the shift lever in
place of the parking brake.
When parking, be sure the
parking brake is fully
engaged.

the assistance of others,
or pets unattended in your
vehicle. Additionally, the
temperature inside a closed
vehicle on a warm day can
quickly become high
enough to cause a
significant risk of injury or
death to people and pets.
To release the parking brake: 1. Shift the transmission to P (Park). Hold the brake
pedal down.
2. Pull the parking brake handle up until you can press the
release button.
3. Hold the release button in as you move the brake handle all
the way down.
Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
Parking Brake Break-in
Break-in the brake shoes whenever
the effect of the parking brake is
weakened or whenever the brake
shoes and/or drums are replaced, in
order to assure the best brake
performance. This procedure can be
performed at the dealer.

moving backward on a hill.
Always drive carefully and
attentively. Depress the
brake pedal when the
vehicle is stopped on a
steep hill. Be especially
careful when stopped on a
hill on frozen or muddy
roads. Failure to prevent the
vehicle from rolling
backwards may result in a
loss of control of the vehicle
and possible serious injury
or death.
. The hill start assist system
is not designed to hold the
vehicle at a standstill on a
hill. Depress the brake
pedal when the vehicle is
stopped on a steep hill.
Failure to do so may cause
the vehicle to roll backwards
and may result in a collision
or serious personal injury.

Vehicle Storage
Tires age when stored normally
mounted on a parked vehicle. Park
a vehicle that will be stored for at
least a month in a cool, dry, clean
area away from direct sunlight to
slow aging. This area should be free
of grease, gasoline, or other
substances that can deteriorate
rubber.
Parking for an extended period can
cause flat spots on the tires that
may result in vibrations while
driving. When storing a vehicle for
at least a month, remove the tires or
raise the vehicle to reduce the
weight from the tires.
Buying New Tires
The original equipment tires
installed were designed with
requirements to specifically
match the vehicle.
Over a dozen critical
specifications that impact the
overall performance of the
vehicle, including brake systemperformance, ride and handling,
traction control, and tire
pressure monitoring
performance were considered.
GM recommends replacing worn
tires in complete sets of four (six
for dual rear wheels). Uniform
tread depth on all tires will help
to maintain the performance of
the vehicle. Braking and
handling performance may be
adversely affected if all the tires
are not replaced at the same
time. If proper rotation and
maintenance have been done,
all four tires (six for dual rear
wheels) should wear out at
about the same time. See
Tire
Rotation 0213 for information
on proper tire rotation. However,
if it is necessary to replace only
one axle set of worn tires, place
the new tires on the rear axle
(two for single rear wheels, four
for dual rear wheels).
{Warning
Tires could explode during
improper service. Attempting
to mount or dismount a tire
could cause injury or death.
Only your dealer or authorized
tire service center should
mount or dismount the tires.
{Warning
Mixing tires of different sizes,
brands, or types may cause
loss of control of the vehicle,
resulting in a crash or other
vehicle damage. Use the
correct size, brand, and type
of tires on all wheels.
This vehicle may have a
different size spare than the
road tires originally installed
on the vehicle. When new, the
vehicle included a spare tire

220 Vehicle Care
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires
are maintained properly. SeeTires
0 200. If air goes out of a tire, it is
much more likely to leak out slowly.
But if there ever is a blowout, here
are a few tips about what to expect
and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop, well off the
road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction as
used in a skid. Stop pressing the
accelerator pedal and steer to
straighten the vehicle. It may be
very bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
underinflated or flat may cause a
blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely underinflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon as
possible.
{Warning
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the
appropriate safety equipment and
training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
(Continued)
Warning (Continued)
anything else, you or others could
be badly injured or killed if the
vehicle slips off the jack. If a jack
is provided with the vehicle, only
use it for changing a flat tire.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place, well off the road,
if possible. Turn on the hazard
warning flashers. See Hazard
Warning Flashers 0104.
{Warning
Changing a tire can be
dangerous. The vehicle can slip
off the jack and roll over or fall
causing injury or death. Find a
level place to change the tire. To
help prevent the vehicle from
moving:
1. Set the parking brake firmly. (Continued)

Warning (Continued)
If you do not follow these steps
exactly, some or all of these
things can hurt you.
Caution
Ignoring these steps could result
in costly damage to the vehicle
that would not be covered by the
vehicle warranty. Trying to start
the vehicle by pushing or pulling it
will not work, and it could damage
the vehicle.

2. Discharged Battery Negative (−) Grounding
Point
3. Good Battery Negative (−) Terminal
4. Good Battery Positive (+) Terminal
1. Check the other vehicle. It must have a 12-volt battery
with a negative ground system.
Caution
If the other vehicle does not have
a 12-volt system with a negative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
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 firmly on both vehicles
involved in the jump start
procedure. Put an automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking
brake.
