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 16 to 20 mph
(26 to 32 km/h), and the threshold level for a full
deployment is 25 to 30 mph (40 to 48 km/h). (The
threshold level can vary, however, with specic vehicle
design, so that it can be somewhat above or below
this range.)
Frontal airbags may inate at different crash speeds.
For example:
If the vehicle hits a stationary object, the airbags
could inate at a different crash speed than if the
object were moving.
If the vehicle hits an object that deforms, the
airbags could inate at a different crash speed than
if the vehicle hits an object does not deform.
If the vehicle hits a narrow object (like a pole) the
airbags 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
airbags 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.

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 amber turn signal bulb
come on at a reduced brightness in daylight when
the following conditions are met:
The ignition is on, and
the exterior lamp band is in the off or AUTO
position.
When the DRL are on, your amber turn signal bulb will
be on at a reduced brightness. The taillamps,
sidemarker and other lamps won’t be on. Your
instrument panel won’t be lit up either.
When you turn the exterior lamp band to the headlamp
position, your low-beam headlamps will come on.
The other lamps that come on with your headlamps will
also come on.
When you turn off the headlamps, the regular lamps will
go off, and your amber turn signal bulb will come on
to the reduced brightness.
Automatic Headlamp System
If you have the automatic headlamps system, the
headlamps will come on automatically when it is dark
enough.
Your vehicle may have a
light sensor located on top
of the instrument panel.
Make sure it is not
covered, or the headlamps
will be on when you
don’t need them.
The system may also turn on the headlamps when
driving through a parking garage or tunnel.

Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not
be covered by your warranty. Do not operate
the engine with the tachometer in the shaded
warning area.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for several seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay
on for several seconds,
then it will ash for
several more.
If the driver’s belt is already buckled, neither the chime
nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, 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 sensor, the airbag
modules, the wiring and the crash sensing and
diagnostic module. For more information on the airbag
system, seeAirbag System on page 1-49.
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.
