Navigation/Radio System
Your vehicle may have a navigation radio system that
includes Radio Data System (RDS) with Program
Type (PTY) selections that will seek out the kind of music
you want to listen to and XM™ Satellite Radio Service
capabilities (if equipped). The radio can also
communicate with the navigation system to broadcast
announcements on traffic, weather, and emergency alert
communications. For information on how to use this
system, see the “Navigation System” manual.
Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen to any
of the sources: radio, cassette tapes, CDs, or DVDs.
However, the rear seat passengers can only control the
sources that the front seat passengers are not listening
to. For example, rear seat passengers may listen to and
control cassette tapes, CDs, or DVDs through the
headphones while the driver listens to the radio through
the front speakers. The rear seat passengers have
control of the volume for each set of headphones.
The front seat audio controls always have priority over
the RSA controls. If the front seat passengers switch the
source for the main radio to a remote source, the RSA will
not be able to control the source. You can operate the
rear seat audio when the main radio is off.
P(Power):Press this button to turn the system on or
off. The rear speakers will be muted when the power
is turned on unless your vehicle is equipped with
the Bose
®audio system.
u(Volume):Turn this knob to increase or to
decrease the volume. The left knob controls the left
headphones and the right knob controls the right
headphones.

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 1-8.
Defensive driving really means “be ready for anything.”
On city streets, rural roads, or freeways, 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. Be ready for their mistakes.
Rear-end collisions are about the most preventable of
accidents. Yet they are common. Allow enough following
distance. It is the best defensive driving maneuver, in
both city and rural driving. You never know when the
vehicle in front of you is going to brake or turn suddenly.
Defensive driving requires that a driver concentrate on
the driving task. Anything that distracts from the driving
task — such as concentrating on a cellular telephone call,
reading, or reaching for something on the oor — makes
proper defensive driving more difficult and can evencause a collision, with resulting injury. Ask a passenger to
help do things like this, or pull off the road in a safe place
to do them yourself. These simple defensive driving
techniques could save your life.
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.

{CAUTION:
Wet brakes can cause accidents. They will not
work as well in a quick stop and may cause
pulling to one side. You could lose control of
the vehicle.
After driving through a large puddle of water
or a car wash, apply your brake pedal lightly
until your brakes work normally.
Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the
water. This can happen if the road is wet enough and
you are going fast enough. When your vehicle is
hydroplaning, it has little or no contact with the road.
Hydroplaning does not happen often. But it can if your
tires do not have much tread or if the pressure in
one or more is low. It can happen if a lot of water is
standing on the road. If you can see reections
from trees, telephone poles, or other vehicles, and
raindrops dimple the water’s surface, there could be
hydroplaning.Hydroplaning usually happens at higher speeds. There
just is not a hard and fast rule about hydroplaning.
The best advice is to slow down when it is raining.
Driving Through Deep Standing Water
Notice:If you drive too quickly through deep
puddles or standing water, water can come in
through your engine’s air intake and badly damage
your engine. Never drive through water that is
slightly lower than the underbody of your vehicle. If
you cannot avoid deep puddles or standing water,
drive through them very slowly.
