In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from
the right front passenger air bag.

Air bags are designed to inflate only once. After an
air bag inflates, you'll need some new parts for your
air bag system. If you don't get them, the air bag
system won't be there to help protect you in another
crash. A new system will include air bag modules
and possibly other parts. The service manual for
your vehicle covers the need to replace other parts.

Your vehicle is equipped with an electronic frontal
sensor, which helps the sensing system distinguish
between a moderate frontal impact and a more severe
frontal impact. Your vehicle is also equipped with a
crash sensing and diagnostic module, which records
information about the frontal air bag system. The
module records information about the readiness of
the system, when the system commands air bag
inflation and driver's safety belt usage at deployment.
The module also records speed, engine rpm, brake
and throttle data.
Let only qualified technicians work on your air
bag systems. Improper service can mean that an
air bag system won't work properly. See your dealer
for service.
NOTICE:
If you damage the covering for the driver's or
the right front passenger's air bag, or the air
bag covering on the driver's and right front
passenger's seatback, the bag may not work
properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right
front passenger's air bag, or both the air bag
module and seatback for the driver's and right
front passenger's side impact air bag. Do not
open or break the air bag coverings.

NEUTRAL (N): In this position, your engine doesn't
connect with the wheels. To restart when you're already
moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
CAUTION:
Shifting out of PARK (P) or NEUTRAL (N) while
your engine is ªracingº (running at high speed) is
dangerous. Unless your foot is firmly on the
brake pedal, your vehicle could move very
rapidly. You could lose control and hit people or
objects. Don't shift out of PARK (P) or
NEUTRAL (N) while your engine is racing.
NOTICE:
Damage to your transaxle caused by shifting out
of PARK (P) or NEUTRAL (N) with the engine
racing isn't covered by your warranty.
AUTOMATIC OVERDRIVE (D): This position is
for normal driving. If you need more power for passing,
and you're:

Going less than 35 mph (55 km/h), push your
accelerator pedal about halfway down.

Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You'll shift down to the next gear and have more power.
NOTICE:
If your vehicle seems to start up rather slowly,
or if it seems not to shift gears as you go faster,
something may be wrong with a transaxle system
sensor. If you drive very far that way, your
vehicle can be damaged. So, if this happens, have
your vehicle serviced right away. Until then, you
can use SECOND (2) when you are driving less
than 35 mph (55 km/h) and AUTOMATIC
OVERDRIVE (D) for higher speeds.

2-35
Warm-Up Shift
Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when the outside
temperature is 35
F (2
C) or colder. You may notice
that the transaxle will shift at a higher vehicle speed
until the engine is warmed up. This is a normal
condition designed to provide heat to the passenger
compartment and defrost the windows more quickly.
THIRD (3): This position is also used for normal
driving, but it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (D).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):

When driving on hilly, winding roads.

When towing a trailer (so there is less shifting
between gears).

When going down a steep hill.
NOTICE:
If your vehicle seems to start up rather slowly,
or if it seems not to shift gears as you go faster,
something may be wrong with a transaxle system
sensor. If you drive very far that way, your
vehicle can be damaged. So, if this happens, have
your vehicle serviced right away. Until then, you
can use SECOND (2) when you are driving less
than 35 mph (55 km/h) and THIRD (3) for
higher speeds.

2-51 Lamps on Reminder
If the driver's door is opened and you turn the ignition
to OFF while leaving the lamps on, you will hear a
warning chime.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset. Fully
functional daytime running lamps are required on all
vehicles first sold in Canada.A light sensor on top of the instrument panel makes
the DRL work, so be sure it isn't covered. The DRL
system will make your reduced intensity high
-beam
headlamps come on in daylight when the following
conditions are met:

The ignition is on,

the exterior lamps control is in AUTO, and

the shift lever is not in PARK (P).
When the DRL are on, only your reduced intensity
high
-beam headlamps will be on. Your instrument panel
won't be lit up.
When it's dark enough outside, the exterior lamps will
come on automatically. When it's bright enough outside,
the exterior lamps will go out and the DRL will turn on.
Of course, you may still turn on the headlamps any time
you need to.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag's electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the air bag sensor, the air
bag modules, the wiring and the diagnostic module.
For more information on the air bag system, see ªAir
Bagº in the Index.
This light will come on
when you start your vehicle,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to ON. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.

Rear Parking Assist (RPA) (Option)
RPA can help you to determine how close an object is to
your rear bumper within a given area, making parking
easier. The four ultrasonic sensors located on the rear
bumper detect the distance to the object in the given
area. It is not intended to be used primarily as a rear
obstacle detection system.
Your vehicle's RPA operates when the shift lever is
moved into REVERSE (R) and the vehicle speed is
less than 3 mph (5 km/h). The RPA display is located
inside the vehicle, above the rear window. It has
three color
-coded lights that can be seen through the
rearview mirror.
RPA can be turned off by
pressing the rear park aid
disable switch located in the
center console switchbank.
When the switch is on an
indicator light will glow on
the switch.

2-126
How the System Works
If the rear park aid disable switch is not on, the rear
parking assist will turn on automatically when the shift
lever is moved into REVERSE (R) and the vehicle
speed is less then 3 mph (5 km/h). When the system
turns on, the three lights on the display will illuminate
for 1.5 seconds to let you know that the system is
working. The red light will flash to indicate that the
system is disabled if your vehicle is moving in
REVERSE (R) at a speed greater then 3 mph (5 km/h).
When shifting into REVERSE (R) with the vehicle
speed less than 3 mph (5 km/h) and an object is
detected, one of the following will occur:
A chime will sound the first time an object is detected,
if the object is between 20 inches (0.5 m) and
5 feet (1.5 m) away.
RPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (2.5 cm) tall, but cannot detect
objects that are above liftgate level. In order for the rear
sensors to recognize an object, it must be within
operating range.

2-127
When the System Does Not Seem to Work Properly
The light will flash red when shifting into REVERSE (R)
if a trailer was attached to your vehicle, or a bicycle or an
object was on the back of, or hanging out of your liftgate
during your last drive cycle. The light will continue to
flash whenever in REVERSE (R), until your vehicle is
driven forward at least 15 mph (25 km/h) without any
obstructions behind the vehicle.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. 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. If after cleaning the rear bumper and then
driving forward at least 15 mph (25 km/h), the display
continues to flash red, see your dealer.
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.
