Navigation/Radio System
Your vehicle may have a navigation radio system.
The navigation system has built-in features intended
to minimize driver distraction. Technology alone,
no matter how advanced, can never replace your
own judgment. See the Navigation System manual for
some tips to help you reduce distractions while driving.
Rear Seat Entertainment (RSE)
System
Your vehicle may have a DVD Rear Seat Entertainment
(RSE) system. The RSE system works with the
vehicle’s audio system. The DVD player is part of the
front radio. The RSE system includes a radio with a
DVD player, a video display screen, audio/video jacks,
two wireless headphones, and a remote control.
SeeRadio(s) (MP3) on page 3-87for more information
on the vehicle’s audio/DVD system.
Before You Drive
The RSE is designed for rear seat passengers only.
The driver cannot safely view the video screen
while driving and should not try to do so.
In severe or extreme weather conditions the RSE
system might or might not work until the temperature
is within the operating range. The operating range
for the RSE system is above−4°F (−20°C) or below
140°F (60°C). If the temperature of your vehicle is
outside of this range, heat or cool the vehicle until
the temperature is within the operating range of
the RSE system.
Parental Control
The RSE system may have a Parental Control feature,
depending on which radio you have. To enable Parental
Control, press and hold the radio power button for more
than two seconds to stop all system features such as:
radio, video screen, RSA, DVD and/or CD. While
Parental Control is on, a padlock icon displays.
When the radio is turned back on, Parental Control
is unlocked.

Audio Output
Audio from the DVD player or auxiliary inputs can be
heard through the following possible sources:
Wireless Headphones
Vehicle Speakers
Vehicle wired headphone jacks on the rear seat
audio system, if your vehicle has this feature.
The RSE system always transmits the audio signal to
the wireless headphones, if there is audio available.
See “Headphones” earlier in this section for more
information.
The DVD player is capable of outputting audio to the
wired headphone jacks on the RSA system, if your
vehicle has this feature. The DVD player can be
selected as an audio source on the RSA system.
SeeRear Seat Audio (RSA) on page 3-125for more
information.
When a device is connected to the A/V jacks, or the
radio’s auxiliary input jack, if your vehicle has this
feature, the rear seat passengers are able to hear
audio from the auxiliary device through the wireless
or wired headphones. The front seat passengers
are able to listen to playback from this device through
the vehicle speakers by selecting AUX as the source
on the radio.
Video Screen
The video screen is located in the overhead console.
To use the video screen, do the following:
1. Push the release button located on the overhead
console.
2. Move the screen to the desired position.
When the video screen is not in use, push it up into
its locked position.
If a DVD is playing and the screen is raised to its
locked position, the screen remains on; this is normal,
and the DVD continues to play through the previous
audio source. Use the remote control
Pbutton
or
Zthe disc to turn off the screen.
The overhead console contains the infrared receivers
for the wireless headphones and the infrared receivers
for the remote control. They are located at the rear
of the console.

Antilock Brake System (ABS)
Your vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that will help
prevent a braking skid.
When you start the engine and begin to drive away,
ABS will check itself. You might hear a momentary
motor or clicking noise while this test is going on, and
you might even notice that the brake pedal moves
a little. This is normal.
If there is a problem with
ABS, this warning light will
stay on. SeeAntilock
Brake System Warning
Light on page 3-48.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.ABS can change the brake pressure faster than any
driver could. The computer is programmed to make the
most of available tire and road conditions. This can
help you steer around the obstacle while braking hard.
As you brake, the computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.
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 the 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 antilock work for you. You might hear
the antilock pump or motor operate, and feel the
brake pedal pulsate, but this is normal.
4-5

Braking in Emergencies
With ABS, you can steer and brake at the same time. In
many emergencies, steering can help you more than
even the very best braking.
Panic Brake Assist
Your vehicle has a Panic Brake Assist feature designed
to assist the driver in stopping or decreasing vehicle
speed in emergency driving conditions. This feature uses
the Electronic Stability Control (ESC) hydraulic brake
control module to supplement the power brake system
under conditions where the driver has quickly and
forcefully applied the brake pedal in an attempt to quickly
stop or slow down the vehicle. The ESC hydraulic brake
control module increases brake pressure at each corner
of the vehicle until the Antilock Brake System (ABS)
activates. Minor brake pedal pulsations or pedal
movement during this time is normal and the driver
should continue to apply the brake pedal as the driving
situation dictates. The Panic Brake Assist feature will
automatically disengage when the brake pedal is
released or brake pedal pressure is quickly decreased.
StabiliTrak®System
Your vehicle has the StabiliTrak®system which
combines antilock brake, traction and stability control
systems and helps the driver maintain directional control
of the vehicle in most driving conditions.
When you rst start your vehicle and begin to drive
away, the system performs several diagnostic checks to
ensure there are no problems. You may hear or feel
the system working. This is normal and does not mean
there is a problem with your vehicle. The system
should initialize before the vehicle reaches 20 mph
(32 km/h). In some cases, it may take approximately
two miles of driving before the system initializes.
If the system fails to turn on or activate, the StabiliTrak
®
light along with one of the following messages will be
displayed on the Driver Information Center (DIC):
TRACTION CONTROL OFF, SERVICE TRACTION
CONTROL, SERVICE STABILITRAK. If you see these
conditions, turn the vehicle off, wait 15 seconds, and then
turn it back on again to reset the system. If any of these
messages still appear on the Driver Information Center
(DIC), your vehicle should be taken in for service. For
more information on the DIC messages, seeDriver
Information Center (DIC) on page 3-57.
4-6

Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds
are based on good weather and road conditions. Under
less favorable conditions you will want to go slower.
If you need to reduce your speed as you approach
a curve, do it before you enter the curve, while the front
wheels are straight ahead.
Try to adjust your speed so you can drive through the
curve. Maintain a reasonable, steady speed. Wait
to accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-4.
Steering in Emergencies
There are times when steering can be more effective than
braking. For example, you come over a hill and nd a
truck stopped in your lane, or a car suddenly pulls out
from nowhere, or a child darts out from between parked
cars and stops right in front of you. You can avoid these
problems by braking — if you can stop in time. But
sometimes you cannot; there is not room. That is the time
for evasive action — steering around the problem.
Your vehicle can perform very well in emergencies like
these. First, apply the brakes. SeeBraking on
page 4-4. It is better to remove as much speed as youcan from a possible collision. Then steer around the
problem, to the left or right depending on the space
available.
An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended 9 and 3 o’clock positions, you
can turn it a full 180 degrees very quickly without
removing either hand. But you have to act fast, steer
quickly, and just as quickly straighten the wheel
once you have avoided the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving
at all times and wear safety belts properly.
