CD track. It will also display
turn-by-turn navigation information if
the vehicle has a navigation radio.
The images are projected through
the HUD lens located on the driver's
side of the instrument panel.
Notice:If you try to use the HUD
image as a parking aid, you may
misjudge the distance and
damage your vehicle. Do not use
the HUD image as a parking aid.
The tap shift gear will also appear
on the HUD if the vehicle has tap
shift and it is active.
The HUD information can be
displayed in one of three languages,
English, French, or Spanish. The
speedometer reading and other
numerical values can be displayed
in either English or metric units.
The language selection is changed
through the radio and the units of
measurement is changed through
the trip computer in the Driver
Information Center (DIC). See
AM-FM Radioon page 6‑12andDriver Information Center (DIC)on page 4‑25.

6-2 Infotainment System
Introduction
Read the following pages to
become familiar with the audio
system's features.
{WARNING
Taking your eyes off the road for
extended periods could cause a
crash resulting in injury or death
to you or others. Do not give
extended attention to
entertainment tasks while driving.
This system provides access to
many audio and non audio listings. To minimize taking your eyes off the
road while driving, do the following
while the vehicle is parked:
.Become familiar with the
operation and controls of the
audio system.
.Set up the tone, speaker
adjustments, and preset radio
stations.
For more information, see Defensive
Driving on page 8‑3.
Notice: Contact your dealer/
retailer before adding any
equipment.
Adding audio or communication
equipment could interfere with
the operation of the vehicle's
engine, radio, or other systems,
and could damage them. Follow
federal rules covering mobile
radio and telephone equipment. The vehicle has Retained
Accessory Power (RAP). With RAP,
the audio system can be played
even after the ignition is turned off.
See
Retained Accessory Power
(RAP)
on page 8‑20for more
information.
Navigation/Radio System
For vehicles with a navigation radio
system, see the separate Navigation
System manual.
Theft-Deterrent Feature
The theft-deterrent feature works by
learning a portion of the Vehicle
Identification Number (VIN) to the
infotainment system. The
infotainment system does not
operate if it is stolen or moved to a
different vehicle.

Driving and Operating 8-3
Defensive Driving
Defensive driving means“always
expect the unexpected.” The first
step in driving defensively is to wear
your safety belt, see Safety Belts
on
page 2‑10.
{WARNING
Assume that other road users
(pedestrians, bicyclists, and other
drivers) are going to be careless
and make mistakes. Anticipate
what they might do and be ready.
In addition:
.Allow enough following
distance between you and
the driver in front of you.
.Focus on the task of driving.
Driver distraction can cause
collisions resulting in injury or
possible death. These simple
defensive driving techniques
could save your life.
Drunk Driving
{WARNING
Drinking and then driving is very
dangerous. Your reflexes,
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. 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.
Death and injury associated with
drinking and driving is a global
tragedy.
Alcohol affects four things that
anyone needs to drive a vehicle:
judgment, muscular coordination,
vision, and attentiveness. Police records show that almost
40 percent 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
17,000 annual motor vehicle-related
deaths have been associated with
the use of alcohol, with about
250,000 people injured.
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.

8-4 Driving and Operating
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.
Control of a Vehicle
The following three systems help to
control the vehicle while
driving —brakes, steering, and
accelerator. At times, as when
driving on snow or ice, it is easy to
ask more of those control systems
than the tires and road can provide.
Meaning, you can lose control of the
vehicle. See Traction Control
System (TCS) on page 8‑34.
Adding non-dealer/non-retailer
accessories can affect vehicle
performance. See Accessories and
Modifications on page 9‑3.
Braking
See Brake System Warning Lighton page 4‑20.
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it 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 100 km/h
(60 mph) travels 20 m (66 ft). That
could be a lot of distance in an
emergency, so keeping enough
space between the 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 with a lot of heavy
braking. Keeping pace with the
traffic and allowing realistic following
distances eliminates a lot of
unnecessary braking. That means
better braking and longer brake life.
