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. For
better radio reception, most AM radio stations will
boost the power levels during the day, and then
reduce these levels during the night. Static can also
occur when things like storms and power lines
interfere with radio reception. When this happens,
try reducing the treble on your radio.
FM Stereo
FM stereo will give the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM
signals, causing the sound to fade in and out.
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 may cause loss of XM
signal for a period of time. The radio may display
NO XM SIGNAL to indicate interference.
Care of Your CDs
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 will 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 Player
Do not use CD lens cleaners for CD players
because the lens of the CD optics can become
contaminated by lubricants.

Fixed Mast Antenna
This type of antenna is called a xed mast
antenna. It is mounted at the center of the roof,
just behind the windshield.
The mast antenna can withstand most car washes
without being damaged. If the mast should ever
become slightly bent, straighten it out by hand.
If the mast is badly bent, replace it.
Check occasionally to make sure the mast is still
tightened to the roof. If tightening is required,
tighten by hand.
If you are putting a protective cover over the
vehicle, remove the mast by hand.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located at
the rear of the vehicle. Keep this antenna clear of
snow and ice build up for clear radio reception.
If your vehicle has a sunroof, the performance of
the XM™ system may be affected if the sunroof
is open.
If your vehicle has a roof rack, 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.

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
Enhanced Traction System (ETS) on page 246.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modifications on page 289.
Braking
SeeBrake System Warning Light on page 185.
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.
242

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.
If your vehicle’s engine ever stops while you are
driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder to
push down. If the engine stops, you will still have
some power brake assist. But you will use it
when you brake. Once the power assist is used
up, it may take longer to stop and the brake pedal
will be harder to push.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modifications on page 289.Anti-Lock Brake System (ABS)
Your vehicle may have the Anti-Lock Brake
System (ABS), an advanced electronic braking
system that will help prevent a braking skid.
If your vehicle has ABS,
this warning light on the
instrument panel will
come on briey
when you start your
vehicle.
When you start your engine, or when you begin to
drive away, your ABS will check itself. You may
hear a momentary motor or clicking noise
while this test is going on, and you may even
notice that your brake pedal moves or pulses a
little. This is normal.
243

Remember: ABS does not change the time you
need to get your foot up to the brake pedal or
always decrease stopping distance. If you get too
close to the vehicle in front of you, you will not have
time to apply your brakes if that vehicle suddenly
slows or stops. Always leave enough room up
ahead to stop, even though you have ABS.
Using ABS
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 ABS, you can steer and brake at the
same time. However, if you do not have ABS, 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 ABS, 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 ABS, it is different.
SeeAnti-Lock Brake System (ABS) on page 243.
In many emergencies, steering can help you
more than even the very best braking.
245

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.
If your vehicle is in cruise control when the
Enhanced Traction System begins to limit wheel
spin, the cruise control will automatically
disengage. When road conditions allow you to
safely use it again, you may re-engage the cruise
control. SeeCruise Control on page 160.When the system is on,
this warning light will
come on to let you know
there’s a problem.
The Enhanced Traction System warning light may
come on for the following reasons:
If you turn the system off by moving the shift
lever to LOW (L), the warning light will come on
and stay on. To turn the system back on, move
the shift lever back to a position other than
LOW (L). The warning light should go off.
The warning light will come on when you set
your parking brake with the engine running, and
it will stay on if your parking brake does not
release fully. If the transaxle shift lever is in any
position other than LOW (L)and the warning
light stays on after your parking brake is fully
released, it means there is a problem with the
system.
If the traction control system is affected by an
engine related problem, the system will turn off
and the warning light will come on.
246

If the warning light stays on, or comes on when
you’re driving, there may be a problem with
your Enhanced Traction System and your vehicle
may need service. When this warning light is
on, the system will not limit wheel spin. Adjust your
driving accordingly.
If the Enhanced Traction System warning light
comes on and stays on for an extended period of
time when the transaxle shift lever is in any
position other than LOW (L), your vehicle needs
service.
To limit wheel spin, especially in slippery road
conditions, you should always leave the Enhanced
Traction System on. But you can turn the system
off if you prefer.
To turn the system off, shift to LOW (L) or
REVERSE (R).When you turn the system off, the Enhanced
Traction System warning light will come on and stay
on when the gear shift is in LOW (L). The warning
light will not come on when the gear shift is in
REVERSE (R). If the Enhanced Traction System is
limiting wheel spin when you shift to LOW (L) or
REVERSE (R) to turn the system off, the warning
light will come on in LOW (L). But the system won’t
turn off right away. It will wait until there’s no longer
a current need to limit wheel spin.
You can turn the system back on at any time by
shifting to AUTOMATIC OVERDRIVE (D) or
INTERMEDIATE (I). The Enhanced Traction
System warning light should go off.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modifications on page 289for more information.

Off-Road Recovery
You may nd that your right wheels have dropped
off the edge of a road onto the shoulder while
you are driving.
If the level of the shoulder is only slightly below
the pavement, recovery should be fairly easy.
Ease off the accelerator and then, if there
is nothing in the way, steer so that your vehicle
straddles the edge of the pavement.You can turn the steering wheel up to one-quarter
turn until the right front tire contacts the pavement
edge. Then turn your steering wheel to go
straight down the roadway.
Passing
The driver of a vehicle about to pass another on a
two-lane highway waits for just the right moment,
accelerates, moves around the vehicle ahead, then
goes back into the right lane again. A simple
maneuver?
Not necessarily! Passing another vehicle on a
two-lane highway is a potentially dangerous move,
since the passing vehicle occupies the same
lane as oncoming traffic for several seconds.
A miscalculation, an error in judgment, or a brief
surrender to frustration or anger can suddenly
put the passing driver face to face with the worst
of all traffic accidents — the head-on collision.
So here are some tips for passing:
Drive ahead. Look down the road, to the
sides, and to crossroads for situations
that might affect your passing patterns. If you
have any doubt whatsoever about making
a successful pass, wait for a better time.
251

While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration, or
braking, including reducing vehicle speed by
shifting to a lower gear. Any sudden changes could
cause the tires to slide. You may not realize the
surface is slippery until your vehicle is skidding.
Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road to
make a mirrored surface — and slow down when
you have any doubt.
If you have the Anti-Lock Brake System (ABS),
remember: It helps avoid only the braking skid. If
you do not have ABS, then in a braking skid,
where the wheels are no longer rolling, release
enough pressure on the brakes to get the wheels
rolling again. This restores steering control.
Push the brake pedal down steadily when you
have to stop suddenly. As long as the wheels are
rolling, you will have steering control.Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to
be impaired — by alcohol or drugs, with night
vision problems, or by fatigue.
Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust the inside rearview mirror to reduce the
glare from headlamps behind you.
Since you cannot see as well, you may need
to slow down and keep more space between
you and other vehicles.
Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe
place and rest.
