When Should an Airbag Inate?
The driver’s and right front passenger’s frontal airbags
are designed to inate in moderate to severe frontal
or near-frontal crashes. But they are designed to inate
only if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account
a variety of desired deployment and non-deployment
events and are used to predict how severe a crash
is likely to be in time for the airbags to inate and help
restrain the occupants. Whether your frontal airbags
will or should deploy is not based on how fast your
vehicle is traveling. It depends largely on what you hit,
the direction of the impact and how quickly your
vehicle slows down.
In addition, your vehicle has “dual stage” frontal airbags,
which adjust the restraint according to crash severity.
Your vehicle is equipped with electronic frontal sensors,
which help the sensing system distinguish between a
moderate frontal impact and a more severe frontal
impact. For moderate frontal impacts, these airbags
inate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs.If the front of your vehicle goes straight into a wall
that does not move or deform, the threshold level for
the reduced deployment is about 12 to 16 mph
(19 to 26 km/h), and the threshold level for a full
deployment is about 20 to 25 mph (32 to 40 km/h).
(The threshold level can vary, however, with specic
vehicle design, so that it can be somewhat above
or below this range.)
Airbags may inate at different crash speeds.
For example:
If the vehicle hits a stationary object, the airbag
could inate at a different crash speed than if
the object were moving.
If the object deforms, the airbag could inate at a
different crash speed than if the object does not
deform.
If the vehicle hits a narrow object (like a pole) the
airbag could inate at a different crash speed
than if the vehicle hits a wide object (like a wall).
If the vehicle goes into an object at an angle the
airbag could inate at a different crash speed
than if the vehicle goes straight into the object.
The frontal airbags (driver and right front passenger)
are not intended to inate during vehicle rollovers, rear
impacts, or in many side impacts because ination
would not likely help the occupants.

In many crashes severe enough to inate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from
the passenger air bag.
Air bags are designed to inate only once. After
an air bag inates, 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 electronic frontal
sensors, which help 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 ination and driver’s safety belt
usage at deployment. The module also records
speed, engine RPM, brake and throttle data.
Let only qualied 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 passenger’s airbag, the bag may not work
properly. You may have to replace the airbag module
in the steering wheel or both the airbag module and
the instrument panel for the passenger’s airbag.
Do not open or break the airbag coverings.
Airbag Off Switch
Your vehicle has a switch inside the glovebox that you
can use to turn off the passenger’s frontal airbag.United States

Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps and the
instrument panel lights when the exterior lamps knob is
turned to AUTO. The radio lights will also be on.
Your vehicle is equipped with a light sensor on the top
of the instrument panel. Be sure it is not covered or
the system will be on whenever the ignition is on.
The system may also turn on your lights when driving
through a parking garage, heavy overcast weather
or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems so
that driving under bridges or bright overhead street
lights does not affect the system. The DRL and
automatic headlamp system will only be affected when
the light sensor sees a change in lighting lasting
longer than the delay.
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is off.
Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake,
or until you shift out of PARK (P).You may be able to turn off your automatic headlamp
system. See “Daytime Running Lamps (DRL)” later
in this section for more information.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in the full bright position. See “Instrument
Panel Brightness” underInterior Lamps on page 3-14.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Lamps On Reminder
A reminder tone will sound when your headlamps or
parking lamps are manually turned on, the driver’s door is
open and your ignition is in OFF or ACCESSORY. To turn
the tone off, turn the knob all the way counterclockwise.
In the automatic mode, the headlamps turn off once the
ignition key is in OFF.

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
rst sold in Canada.
The DRL system will make your headlamps come on
at reduced brightness when the following conditions
are met:
The ignition is on.
The exterior lamps knob is in AUTO.
The light sensor detects daytime light.
The transmission is not in PARK (P).
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won’t
be on. The instrument panel won’t be lit up either.When it begins to get dark, the headlamps will
automatically switch from DRL to the regular headlamps.
To idle your vehicle with the DRL off, put your vehicle’s
transmission in PARK (P). The DRL will stay off until
you shift out of PARK (P).
Fog Lamps
Use your fog lamps for better vision in foggy or misty
conditions. Your ignition must be in RUN for your
fog lamps to work.
-(Fog Lamps):Press this button located on the
exterior lamps control to turn the fog lamps on or off.
The fog lamps will go off whenever you turn on the
high-beam headlamps. When the high beams are turned
off, the fog lamps will come on again.
O(Fog Lamp Indicator Light):This light located on
the exterior lamps control illuminates when the
fog lamps are turned on.

Parade Dimming
This feature prohibits the dimming of your instrument
panel displays during daylight while your headlamps
are on. When the light sensor reads darkness outside,
you will be able to dim your instrument panel displays
once again.
Perimeter Lighting
When the button with the unlock symbol on the remote
keyless entry transmitter is pressed, the DRL, parking
lamps and back-up lamps will come on if it is dark
enough outside.
This feature can be personalized for up to two drivers.
SeeDIC Vehicle Personalization on page 3-52for
more information.
Front Map Lamps
If your vehicle has front map lamps, they are located on
the inside rearview mirror. They will automatically
come on for about 40 seconds when the doors are
unlocked with the remote keyless entry transmitter or
until the ignition key is turned to RUN or ACCESSORY.
The lamps will also stay on for about 40 seconds
after you exit the vehicle unless you lock the doors with
the remote keyless entry transmitter.
You can also turn the lamps on and off by pressing the
button near each lamp.
Battery Rundown Protection
This feature shuts off all lamps that are left on for more
than 10 minutes when the ignition is off. This will keep
your battery from running down.

Airbag Readiness Light
There is an air bag readiness light on the instrument
panel cluster, 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
sensors, the air bag modules, the wiring and the crash
sensing and diagnostic module. For more information
on the air bag system, seeAirbag Systems on
page 1-40.
This light will come on
when you start your
vehicle, and it will ash 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 airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away if the airbag
readiness light stays on after you start your
vehicle.
The air bag readiness light should ash for a few
seconds when you turn the ignition key to RUN. If the
light doesn’t come on then, have it xed so it will
be ready to warn you if there is a problem.
