XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast-to-coast in the 48 contiguous
United States, and in Canada. Just as with FM,
tall buildings or hills can interfere with satellite
radio signals, causing the sound to fade in and out.
In addition, traveling or standing under heavy
foliage, bridges, garages, or tunnels can cause
loss of the XM™ signal for a period of time.
The radio could display NO XM SIGNAL to indicate
interference.
Care of Your CDs and DVDs
Handle CDs carefully. Store them in their original
cases or other protective cases and away from
direct sunlight and dust. The CD player scans the
bottom surface of the disc. If the surface of a
CD is damaged, such as cracked, broken,
or scratched, the CD does not play properly or not
at all. If the surface of a CD is soiled, take a
soft, lint free cloth or dampen a clean, soft cloth in
a mild, neutral detergent solution mixed with
water, and clean it. Make sure the wiping process
starts from the center to the edge.Do not touch the bottom side of a CD while
handling it; this could damage the surface. Pick up
CDs by grasping the outer edges or the edge of
the hole and the outer edge.
Care of the CD and DVD Player
The use of CD lens cleaners for CDs is not
advised, due to the risk of contaminating the lens
of the CD optics with lubricants internal to the
CD mechanism.

Rear Side Window Antenna
Your AM-FM antenna is located in the passenger
rear side windows. Be sure that the inside
surfaces of the rear side windows are not
scratched and that the lines on the glass are not
damaged. If the inside surfaces are damaged, they
could interfere with radio reception.
Notice:Using a razor blade or sharp object to
clear the inside of the rear side windows
may affect radio reception or damage the rear
window defogger. Repairs would not be
covered by your warranty. Do not clear the
inside of the rear side windows with sharp
objects.
Notice:Do not apply aftermarket glass tinting
with metallic lm. The metallic lm in some
tinting materials will interfere with or distort the
incoming radio reception. Any damage
caused to your antenna due to metallic tinting
materials will not be covered by your
warranty.
Because this antenna is built into your rear side
window, there is a reduced risk of damage caused
by car washes and vandals.If you choose to add an aftermarket cellular
telephone to your vehicle, and the antenna needs
to be attached to the glass, be sure that you
do not damage the grid lines for the AM-FM
antennas or place the cellular telephone antenna
over the grid lines.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on
the roof of your vehicle. Keep this antenna clear of
snow and ice build up for clear radio reception.
The performance of the XM™ system may
be affected if the sunroof is open.
Loading items onto the roof of your vehicle can
interfere with the performance of the XM™ system.
Make sure the XM™ Satellite Radio antenna is
not obstructed.

Your Driving, the Road, and
Your Vehicle
Defensive Driving
The best advice anyone can give about driving is:
Drive defensively.
Please start with a very important safety device in
your vehicle: Buckle up. SeeSafety Belts: They
Are for Everyone on page 38.
{CAUTION:
Defensive driving really means “Be ready
for anything.” On city streets, rural roads,
or expressways, it means “Always expect
the unexpected.” Assume that pedestrians
or other drivers are going to be careless
and make mistakes. Anticipate what they
might do and be ready. Rear-end
collisions are about the most preventable
of accidents. Yet they are common. Allow
enough following distance. Defensive
driving requires that a driver concentrate
on the driving task. Anything that
distracts from the driving task makes
proper defensive driving more difficult
and can even cause a collision, with
resulting injury. Ask a passenger to help
do these things, or pull off the road in a
safe place to do them. These simple
defensive driving techniques could save
your life.
356

Drunken Driving
Death and injury associated with drinking and
driving is a national tragedy. It is the number one
contributor to the highway death toll, claiming
thousands of victims every year.
Alcohol affects four things that anyone needs to
drive a vehicle:
Judgment
Muscular Coordination
Vision
Attentiveness
Police records show that almost half of all motor
vehicle-related deaths involve alcohol. In most
cases, these deaths are the result of someone who
was drinking and driving. In recent years, more
than 16,000 annual motor vehicle-related deaths
have been associated with the use of alcohol, with
more than 300,000 people injured.Many adults — by some estimates, nearly half the
adult population — choose never to drink
alcohol, so they never drive after drinking. For
persons under 21, it is against the law in
every U.S. state to drink alcohol. There are good
medical, psychological, and developmental
reasons for these laws.
The obvious way to eliminate the leading highway
safety problem is for people never to drink
alcohol and then drive. But what if people do?
How much is “too much” if someone plans
to drive? It is a lot less than many might think.
Although it depends on each person and situation,
here is some general information on the problem.
The Blood Alcohol Concentration (BAC) of
someone who is drinking depends upon four things:
The amount of alcohol consumed
The drinker’s body weight
The amount of food that is consumed before
and during drinking
The length of time it has taken the drinker to
consume the alcohol
357

According to the American Medical Association, a
180 lb (82 kg) person who drinks three 12 ounce
(355 ml) bottles of beer in an hour will end up with
a BAC of about 0.06 percent. The person would
reach the same BAC by drinking three 4 ounce
(120 ml) glasses of wine or three mixed drinks if
each had 1-1/2 ounces (45 ml) of liquors like
whiskey, gin, or vodka.It is the amount of alcohol that counts. For
example, if the same person drank three double
martinis (3 ounces or 90 ml of liquor each)
within an hour, the person’s BAC would be close
to 0.12 percent. A person who consumes food
just before or during drinking will have a somewhat
lower BAC level.
There is a gender difference, too. Women
generally have a lower relative percentage of body
water than men. Since alcohol is carried in body
water, this means that a woman generally will
reach a higher BAC level than a man of her same
body weight will when each has the same
number of drinks.
The law in most U.S. states, and throughout
Canada, sets the legal limit at 0.08 percent. In
some other countries, the limit is even lower. For
example, it is 0.05 percent in both France and
Germany. The BAC limit for all commercial drivers
in the United States is 0.04 percent.
The BAC will be over 0.10 percent after three to six
drinks (in one hour). Of course, as we have seen, it
depends on how much alcohol is in the drinks, and
how quickly the person drinks them.
358

But the ability to drive is affected well below a
BAC of 0.10 percent. Research shows that
the driving skills of many people are impaired at a
BAC approaching 0.05 percent, and that the
effects are worse at night. All drivers are impaired
at BAC levels above 0.05 percent. Statistics
show that the chance of being in a collision
increases sharply for drivers who have a BAC of
0.05 percent or above. A driver with a BAC level of
0.06 percent has doubled his or her chance of
having a collision. At a BAC level of 0.10 percent,
the chance of this driver having a collision is
12 times greater; at a level of 0.15 percent, the
chance is 25 times greater!
The body takes about an hour to rid itself of the
alcohol in one drink. No amount of coffee or number
of cold showers will speed that up. “I will be careful”
is not the right answer. What if there is an
emergency, a need to take sudden action, as when
a child darts into the street? A person with even a
moderate BAC might not be able to react quickly
enough to avoid the collision.There is something else about drinking and driving
that many people do not know. Medical research
shows that alcohol in a person’s system can make
crash injuries worse, especially injuries to the
brain, spinal cord, or heart. This means that when
anyone who has been drinking — driver or
passenger — is in a crash, that person’s chance
of being killed or permanently disabled is
higher than if the person had not been drinking.
{CAUTION:
Drinking and then driving is very
dangerous. Your reexes, perceptions,
attentiveness, and judgment can be
affected by even a small amount of
alcohol. You can have a serious — or
even fatal — collision if you drive after
drinking. Please do not drink and drive or
ride with a driver who has been drinking.
Ride home in a cab; or if you are with a
group, designate a driver who will not
drink.
359

Control of a Vehicle
You have three systems that make your vehicle
go where you want it to go. They are the brakes,
the steering, and the accelerator. All three
systems have to do their work at the places where
the tires meet the road.
Sometimes, as when you are driving on snow or
ice, it is easy to ask more of those control systems
than the tires and road can provide. That means
you can lose control of your vehicle. See
StabiliTrak
®System on page 363.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 444.
Braking
SeeBrake System Warning Light on page 249.
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake
pedal. That is perception time. Then you have to
bring up your foot and do it. That is reaction time.Average reaction time is about three-fourths of a
second. But that is only an average. It might be less
with one driver and as long as two or three seconds
or more with another. Age, physical condition,
alertness, coordination, and eyesight all play a part.
So do alcohol, drugs, and frustration. But even in
three-fourths of a second, a vehicle moving at
60 mph (100 km/h) travels 66 feet (20 m). That
could be a lot of distance in an emergency, so
keeping enough space between your vehicle and
others is important.
And, of course, actual stopping distances vary
greatly with the surface of the road, whether it is
pavement or gravel; the condition of the road,
whether it is wet, dry, or icy; tire tread; the condition
of the brakes; the weight of the vehicle; and the
amount of brake force applied.
Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic.
This is a mistake. The brakes may not have time to
cool between hard stops. The brakes will wear out
much faster if you do a lot of heavy braking. If you
keep pace with the traffic and allow realistic
following distances, you will eliminate a lot of
unnecessary braking. That means better braking
and longer brake life.
