SERVICE AC SYSTEM - 14: This message
appears when the electronic sensors that control the air
conditioning and heating systems are no longer working.
Have the climate control system serviced if you notice a
drop in heating and air conditioning efficiency.
SERVICE AIR BAG
- 83: There is a problem with the
supplemental inflatable restraint (air bag) system when this
message appears. Let only a qualified technician work on
your vehicle. See your dealership for service at once.
SERVICE CHARGING SYS
- 102: This message
will display when a problem with the charging system
has been detected. Have your vehicle serviced at
your dealership.
SERVICE ELECTRICAL SYS
- 106: This message
will display if an electrical problem has occurred within
the Powertrain Control Module (PCM) or the ignition
switch. Have your vehicle serviced by your dealership.
SERVICE FUEL SYSTEM
- 101: The Powertrain
Control Module (PCM) has detected a problem within
the fuel system when this message appears. See your
dealership for service.
SERVICE IDLE CONTROL
- 107: A problem
with the idle control has occurred when this message
displays. Take your vehicle to your dealership
for service.SERVICE STABILITY SYS
- 54 : If you ever see the
SERVICE STABILITY SYS message, it means there
may be a problem with your stability enhancement
system. If you see this message, try to reset the system
(stop; turn off the engine; then start the engine again). If
the SERVICE STABILITY SYS message still comes on,
it means there is a problem. You should see your dealer
for service. Reduce your speed and drive accordingly.
A single chime will also sound when this message
is displayed.
STABILITY SYS ENGAGED
- 55 : You may see the
STABILITY SYS ENGAGED message on the Driver
Information Center. It means that an advanced,
computer
-controlled system has come on to help your
vehicle continue to go in the direction in which you're
steering. This stability enhancement system activates
when the computer senses that your vehicle is just
starting to spin, as it might if you hit a patch of ice or
other slippery spot on the road. When the system is on,
you may hear a noise or feel a vibration in the brake
pedal. This is normal.

2-95
TOP SPEED FUEL CUT-OFF - 111 : This message
will appear when the Powertrain Control Module (PCM)
senses that the maximum speed for your vehicle has
been reached. The speed of your vehicle will surge as
the fuel supply is cut off. This allows your vehicle to
stay in a safe tire operating range. The top speed is set
based on the top speed rating of the tires.
TRACTION ENGAGED
- 91 : When your traction
control system is limiting wheel spin, the TRACTION
ENGAGED message will be displayed. Slippery road
conditions may exist if this message is displayed, so
adjust your driving accordingly. This message will stay
on for a few seconds after the traction control system
stops limiting wheel spin.
TRACTION OFF
- 89: This message will be displayed
after the traction control has been turned off by the
button on the center console.
TRACTION READY
- 90: This message informs the
driver that the traction control system is available. This
occurs when the traction control switch on the console
has been returned to ON (pressing the button once turns
the traction control system off: pressing the button
again turns the system back on). This message will
automatically disappear from the display after
five seconds.TRACTION SUSPENDED
- 56: This message
displays when the traction control system has been
temporarily shut off because your vehicle's brakes have
overheated. This message does not indicate a problem
with your vehicle's traction control system. After a few
minutes, the traction control system will be available
again and the TRACTION READY message
will appear.
TRANS HOT IDLE ENGINE
- 112: This message
indicates that the transaxle fluid in your vehicle is too
hot. Stop and allow your vehicle to idle until it cools
down or until this message is removed.
TRUNK OPEN
- 24: This message indicates that the
trunk is open when the ignition is on.
TURN SIGNAL ON
- 20: This message is a reminder,
after driving about a mile, that you have the turn signal
on. A multiple chime will also sound when this message
is displayed.
VEHICLE OVERSPEED
- 52: This message is
displayed when the vehicle speed exceeds a certain limit
as required by some export countries. A continuous
chime will also sound when this message is displayed.

2-104
The Night Vision System image appears as a ªheat
imageº that looks something like a black and white
photographic negative. It appears in front of the driver
just above the front edge of the hood.Remember that the Night Vision System can only help
you see objects that are warmer or colder than the
surroundings. It can't sense things like brake lights, turn
signals or emergency flashers, traffic lights or signs.

2-108
A chime will sound the first time an object is detected.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above trunk level. In order for the rear
sensors to recognize an object, it must be within
operating range.If the URPA system is not functioning properly, the
display will flash red, indicating that there is a problem.
The light will also flash red while driving if a trailer is
attached to your vehicle, or a bicycle or object is on the
back of, or hanging out of your trunk. The light will
continue to flash until the trailer or the object is
removed and your vehicle is driven forward at least
15 mph (25 km/h). It may also flash red if the ultrasonic
sensors are not kept clean. So be sure to keep your rear
bumper free of mud, dirt, snow, ice and slush or the
system may not work properly. If after cleaning the rear
bumper and driving forward at least 15 mph (25 km/h),
the display continues to flash red, see your dealer.
It may also flash red if your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph (5 km/h).
Other conditions that may affect system performance
include things like the vibrations from a jackhammer or
the compression of air brakes on a very large truck.
As always, drivers should use care when backing up a
vehicle. Always look behind you, being sure to check
for other vehicles, obstructions and blind spots. For
cleaning instructions, see ªCleaning Your Vehicleº in
the Index.

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. (See ªSafety Beltsº in the Index.)
Defensive driving really means ªbe ready for anything.º
On city streets, rural roads or freeways, it means
ªalways expect the unexpected.º
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's 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
floor
-- makes proper defensive driving more difficult
and can even cause 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.

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're driving on snow or ice, it's
easy to ask more of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That's perception time. Then you have to bring up your
foot and do it. That's reaction time.
Average reaction time is about 3/4 of a second. But
that's 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 3/4 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's pavement or
gravel); the condition of the road (wet, dry, icy); tire
tread; the condition of your brakes; the weight of the
vehicle and the amount of brake force applied.

4-7
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. Your brakes may not have time to cool between
hard stops. Your 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 engine ever stops while you're driving, brake
normally but don't pump your brakes. If you do, the
pedal may get harder to push down. If your 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.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine and begin to drive away,
your anti
-lock brake system 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 a little. This is normal.
If there's a problem with the
anti
-lock brake system, this
warning light will stay on.
See ªAnti
-Lock Brake
System Warning Lightº in
the Index.

Here's how anti-lock works. Let's say the road is wet. You're
driving safely. Suddenly an animal jumps out in front of you.
You slam on the brakes. Here's 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 front wheel and at
both rear wheels.
The anti
-lock system can change the brake pressure faster
than any driver could. The computer is programmed to
make the most of available tire and road conditions.
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
Remember: Anti
-lock doesn't 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 won't 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
anti
-lock brakes.
