What Will You See After an Airbag
Inates?
After an airbag inates, it quickly deates, so quickly
that some people may not even realize the airbag
inated. Some components of the airbag module — the
steering wheel hub for the driver’s airbag, the
instrument panel for the right front passenger’s bag or
the garnish trim and ceiling of your vehicle near the side
windows — will be hot for a short time. The parts of
the bag that come into contact with you may be warm,
but not too hot to touch. There will be some smoke
and dust coming from the vents in the deated airbags.
Airbag ination does not prevent the driver from
seeing or being able to steer the vehicle, nor does it
stop people from leaving the vehicle.
{CAUTION:
When an airbag inates, there is dust in the
air. This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in
the vehicle should get out as soon as it is safe
to do so. If you have breathing problems but
cannot get out of the vehicle after an airbag
inates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an airbag deployment, you
should seek medical attention.
Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the
airbags inate (if battery power is available). You can
lock the doors again and turn the interior lamps off
by using the door lock and interior lamp controls.

If your vehicle has this feature, some audio controls can
be adjusted at the steering wheel. They include the
following:
xSEEKw:Press the up or the down arrow to go to
the next or to the previous radio station and stay
there. The radio will only seek stations with a strong
signal that are in the selected band.
When a CD is playing, press the up or the down arrow
to go to the next or previous track.
BAND:Press this button to switch between FM1, FM2,
AM, or XM1 or XM2 (if equipped).1–6 (Preset Pushbuttons):Press this button to play
stations that are programmed on the radio preset
pushbuttons. The radio will only seek preset stations
with a strong signal that are in the selected band.
xuw(Volume):Press the up or the down arrow
to increase or to decrease the volume.
>(Mute):Press this button to silence the system.
Press this button again, or any other radio button, to turn
the sound on.
Mute is unavailable when OnStar™ (if equipped)
is active.

listening to the radio and a CD. The inactive CD
will remain safely inside the radio for future listening.
Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range can cause
station frequencies to interfere with each other. Static
can occur on AM stations caused by things like
storms and power lines. Try reducing the treble to
reduce this noise.
3-75

Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down rmly and let anti-lock work for you. You may feel
a slight brake pedal pulsation or notice some noise,
but this is normal.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If you have anti-lock brakes, you can steer and brake at
the same time. However, if you do not have anti-lock
brakes, your rst reaction — to hit the brake pedal hard
and hold it down — may be the wrong thing to do.
Your wheels can stop rolling. Once they do, the vehicle
cannot respond to your steering. Momentum will
carry it in whatever direction it was headed when the
wheels stopped rolling. That could be off the road, into
the very thing you were trying to avoid, or into traffic.
If you do not have anti-lock brakes, use a “squeeze”
braking technique. This will give you maximum braking
while maintaining steering control. You can do this
by pushing on the brake pedal with steadily increasing
pressure.In an emergency, you will probably want to squeeze the
brakes hard without locking the wheels. If you hear or
feel the wheels sliding, ease off the brake pedal.
This will help you retain steering control. If you do have
anti-lock brakes, it is different. SeeAnti-Lock Brake
System (ABS) on page 4-6.
In many emergencies, steering can help you more than
even the very best braking.
Enhanced Traction System (ETS)
Your vehicle may have an Enhanced Traction System
(ETS) that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if
it senses that one or both of the front wheels are
spinning or beginning to lose traction. When this
happens, the system reduces engine power and may
also upshift the transaxle to limit wheel spin. You
may feel or hear the system working, but this is normal.
A LOW TRACTION message will appear on the
Driver Information Center (DIC) when the traction control
system is actively limiting wheel spin. Slippery road
conditions may exist if this message is displayed,
so adjust your driving accordingly.

Steering
Electric Power Steering
If the engine stalls while you are driving, the power
steering assist system will continue to operate until you
are able to stop your vehicle. If you lose power
steering assist because the electric power steering
system is not functioning, you can steer, but it will take
more effort.
If you turn the steering wheel in either direction several
times until it stops, or hold the steering wheel in the
stopped position for an extended amount of time, you
may notice a reduced amount of power steering
assist. The normal amount of power steering assist
should return shortly after a few normal steering
movements.
The electric power steering system does not require
regular maintenance. If you suspect steering system
problems and/or the POWER STEERING message
comes on, contact your dealer for service repairs. See
DIC Warnings and Messages on page 3-37.
Steering Tips
Driving on Curves
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels. If there is no traction, inertia
will keep the vehicle going in the same direction. If
you have ever tried to steer a vehicle on wet ice, you
will understand this.
The traction you can get in a curve depends on the
condition of your tires and the road surface, the angle at
which the curve is banked, and your speed. While
you are in a curve, speed is the one factor you
can control.
Suppose you are steering through a sharp curve.
Then you suddenly apply the brakes. Both control
systems — steering and braking — have to do their work
where the tires meet the road. Unless you have
four-wheel anti-lock brakes, adding the hard braking can
demand too much of those places. You can lose control.

Tire Size
The following illustration shows an example of a typical
passenger vehicle tire size.
(A) Passenger (P-Metric) Tire:The United States
version of a metric tire sizing system. The letter P as the
rst character in the tire size means a passenger
vehicle tire engineered to standards set by the U.S. Tire
and Rim Association.
(B) Tire Width:The three-digit number indicates the
tire section width in millimeters from sidewall to sidewall.
(C) Aspect Ratio:A two-digit number that indicates
the tire height-to-width measurements. For example, if
the tire size aspect ratio is 60, as shown in item C of the
illustration, it would mean that the tire’s sidewall is
60 percent as high as it is wide.(D) Construction Code:A letter code is used to
indicate the type of ply construction in the tire. The letter
R means radial ply construction; the letter D means
diagonal or bias ply construction; and the letter B means
belted-bias ply construction.
(E) Rim Diameter:Diameter of the wheel in inches.
(F) Service Description:These characters represent
the load range and speed rating of the tire. The load
index represents the load carry capacity a tire is certied
to carry. The load index can range from 1 to 279. The
speed rating is the maximum speed a tire is certied
to carry a load. Speed ratings range from A to Z.
Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire pressing
outward on each square inch of the tire. Air pressure
is expressed in pounds per square inch (psi) or
kilopascal (kPa).
Accessory Weight:This means the combined weight
of optional accessories. Some examples of optional
accessories are, automatic transmission, power steering,
power brakes, power windows, power seats, and air
conditioning.
Aspect Ratio:The relationship of a tire’s height to
its width.

Maintenance Footnotes
(a)Visually inspect brake lines and hoses for proper
hook-up, binding, leaks, cracks, chang, etc. Inspect
disc brake pads for wear and rotors for surface
condition. Inspect drum brake linings/shoes for wear or
cracks. Inspect other brake parts, including drums,
wheel cylinders, calipers, parking brake, etc.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing parts or
signs of wear. Inspect power steering lines and hoses
for proper hook-up, binding, leaks, cracks, chang, etc.
(c)Visually inspect hoses and have them replaced if
they are cracked, swollen, or deteriorated. Inspect
all pipes, ttings and clamps; replace with genuine GM
parts as needed. To help ensure proper operation, a
pressure test of the cooling system and pressure
cap and cleaning the outside of the radiator and air
conditioning condenser is recommended at least
once a year.
(d)Visually inspect wiper blades for wear or cracking.
Replace wiper blades that appear worn or damaged
or that streak or miss areas of the windshield.(e)Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors, and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced. Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
The airbag system does not need regular maintenance.
(f)Lubricate all key lock cylinders, door hinges and
latches, hood hinges and latches and trunk lid hinges
and latches. More frequent lubrication may be required
when exposed to a corrosive environment. Applying
silicone grease on weatherstrips with a clean cloth will
make them last longer, seal better, and not stick or
squeak.
(g)Check system for interference or binding and for
damaged or missing parts. Replace parts as needed.
Replace any components that have high effort or
excessive wear. Do not lubricate accelerator or cruise
control cables.
