{CAUTION:
If something is between an occupant and an
airbag, the airbag might not inate properly
or it might force the object into that person
causing severe injury or even death. The path
of an inating airbag must be kept clear. Do
not put anything between an occupant and an
airbag, and do not attach or put anything on
the steering wheel hub or on or near any other
airbag covering. Do not let seat covers block
the ination path of a side impact airbag.
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.

Daytime Running Lamps (DRL)
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, and
·the automatic transmission is not in PARK (P)
or the parking brake is not set on a manual
transmission.
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
automatic transmission in PARK (P). The DRL will
stay off until you shift out of PARK (P). If you have a
manual transmission, set the parking brake when
the ignition is off and then start your vehicle. The DRL
will stay off until you release the parking brake.
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. See
Exterior Lamps on page 3-12for more information. 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. See
Daytime Running Lamps
(DRL) on page 3-14for more information.
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) on
page 3-14for 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
on page 3-16for more information.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
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.

Interior Lamps
O(Exterior and Interior Lamp Controls):These
controls (B) are used to operate the exterior and interior
lamps. Information on the interior lamps follows. For
more information on the exterior lamps, see
Exterior
Lamps on page 3-12.
D(Interior Lamp Control): The interior lamp
control (A) is located to the left of the steering wheel
and is used to adjust the brightness of the instrument
panel lights.
Instrument Panel Brightness
To adjust the brightness of the instrument panel lights,
press lightly on the interior lamp control and release.
The control will extend outward. Turn the control
counterclockwise to brighten and clockwise to dim the
instrument panel lights. Press on the control to return it
to the stored position.
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.

Airbag Readiness Light
There is an airbag readiness light on the instrument
panel cluster, which shows the airbag symbol. The
system checks the airbag's electrical system for
malfunctions. The light tells you if there is an electrical
problem. The system check includes the airbag
sensors, the airbag modules, the wiring and the crash
sensing and diagnostic module. For more information
on the airbag system, see
Airbag System on page 1-38.
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 airbag readiness light stays on after you start the
vehicle or comes on when you are driving, your airbag
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 in¯ate in a crash, or they
could even in¯ate 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 airbag 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.
