Audio System(s)
Your vehicle has the Navigation Audio System. Read the
following pages to familiarize yourself with its features.
{CAUTION:
This system provides you with far greater
access to audio stations and song listings.
Giving extended attention to entertainment
tasks while driving can cause a crash and you
or others can be injured or killed. Always keep
your eyes on the road and your mind on the
drive — avoid engaging in extended searching
while driving.
Keeping your mind on the drive is important for safe
driving. SeeDefensive Driving on page 5-2. Here
are some ways in which you can help avoid distraction
while driving.While your vehicle is parked:
Familiarize yourself with all of its controls.
Familiarize yourself with its operation.
Set up your audio system by presetting your
favorite radio stations, setting the tone, and
adjusting the speakers. Then, when driving
conditions permit, you can tune to your favorite
radio stations using the presets and steering
wheel controls if the vehicle has them.
Notice:Before adding any sound equipment to
your vehicle, such as an audio system, CD player,
CB radio, mobile telephone, or two-way radio,
make sure that it can be added by checking with
your dealer/retailer. Also, check federal rules
covering mobile radio and telephone units. If sound
equipment can be added, it is very important to
do it properly. Added sound equipment may
interfere with the operation of your vehicle’s engine,
radio, or other systems, and even damage them.
Your vehicle’s systems may interfere with the
operation of sound equipment that has been added.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can
be played even after the ignition is turned off.
SeeRetained Accessory Power (RAP) on page 2-24

Keyless Access System
When the engine is started, Driver 1 or Driver 2 will
display on the screen. A message will not appear on the
screen if the driver is unknown. The number on the
back of the transmitter corresponds to driver 1 or
driver 2. The navigation system can store memory points
for drivers 1 and 2 individually. SeeKeyless Access
System on page 2-5for more information.
OnStar®System
When using the OnStar®system, the audio system will
be muted and the navigation voice prompts will be
disabled during the call. The volume of the OnStar
®call
can be adjusted by using the steering wheel volume
controls. SeeOnStar
®System on page 2-41for
more information.
Global Positioning System (GPS)
The navigation system determines the position of your
vehicle by using satellite signals, various vehicle signals,
and map data.
At times, other interferences such as the satellite
condition, road conguration, the condition of the vehicle
and/or other circumstances can interfere with the
navigation system’s ability to determine the accurate
position of the vehicle.The GPS shows the current position of your vehicle using
signals sent by the GPS Satellites of the United States
Department of Defense. When your vehicle is not
receiving signals from the satellites, a symbol will appear
on the map screen. Refer toSymbols on page 4-44.
This system may not be available or interferences may
occur if any of the following are true:
Signals are obstructed by tall buildings, trees, large
trucks, or a tunnel.
Objects are located on the rear shelf.
Satellites are being repaired or improved.
After-market glass tinting has been applied to the
vehicle’s rear windshield.
Notice:Do not apply after-market glass tinting to
the vehicle’s windows. Glass tinting will interfere
with the system’s ability to receive GPS signals and
cause the system to malfunction. You might have
to replace the window to correct the problem.
This would not be covered by your warranty.
For more information if you are experiencing a problem,
seeIf the System Needs Service on page 4-52and
Problems with Route Guidance on page 4-52.

Navigation Audio System
Notice:Before adding any sound equipment to
your vehicle, such as an audio system, CD player,
CB radio, mobile telephone, or two-way radio, make
sure that it can be added by checking with your
dealer/retailer. Also, check federal rules covering
mobile radio and telephone units. If sound
equipment can be added, it is very important to do
it properly. Added sound equipment can interfere
with the operation of your vehicle’s engine, radio,
or other systems, and even damage them.
Your vehicle’s systems can interfere with the
operation of sound equipment that has been added.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. SeeRetained
Accessory Power (RAP) on page 2-24for more
information.
The audio system is operated using navigation system
menus. The audio menus are explained in this section.

Braking
SeeBrake System Warning Light on page 3-50.
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 might 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 could 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 can take longer to stop and
the brake pedal will be harder to push.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 6-3.
