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
18 to 24 mph (29 to 38.5 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.
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.
Side impact airbags are designed to inate in moderate
to severe side crashes. A side impact airbag will
inate if the crash severity is above the system’s
designed “threshold level.” The threshold level can vary
with specic vehicle design. Side impact airbags are
not designed to inate in frontal or near-frontal impacts,
rollovers or rear impacts, because ination would not
likely help the occupant. A side impact airbag will
only deploy on the side of the vehicle that is struck.

When the exterior lamp control is in AUTO and it is dark
enough outside, the DRL will turn off and the low-beam
headlamps at full brightness will turn on. When it is
bright enough outside, the front turn signal lamps will
go off, and the DRL will turn back on. If the vehicle
is started in a dark garage, the automatic headlamp
system will come on immediately. Once the vehicle
leaves 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, the
instrument panel cluster may not be as bright as usual.
Make sure the instrument panel brightness control is
at the highest setting. SeeInstrument Panel Brightness
on page 3-17.
Vehicle’s sold in the U.S. can turn the DRL off.
To do this, turn the band on the exterior lamp control
to off. Turn the band to this position again to turn the
DRL on.
As with any vehicle, the regular headlamp system
should be turned on when needed.Light Sensor
The light sensor for the
DRL and AUTO
headlamps feature is
located on top of
the instrument panel.
If the sensor is covered, it will register that it is dark
outside and the headlamps will turn on to full brightness.
Fog Lamps
Fog lamps provide brighter roadway lighting for better
vision in foggy or misty conditions.
-(Fog Lamps):Turn the second band on the
exterior lamps control lever to this position to turn the
fog lamps on. The band will return to its original position.

2. Press the PASS. button to turn the passenger
climate control system on and off. When the
passenger system is off, the driver’s temperature
setting is also used for the passenger and the
passenger display is off.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. The
length of time needed for warm up will depend on
the outside temperature and the length of time
that has elapsed since your vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.Manual Operation
xw
(Temperature):To manually adjust the
temperature inside the vehicle, press the up arrow on
the temperature control to raise the temperature
and press the down arrow to lower the temperature.
The display will show your selection.
When one temperature is displayed, the driver
temperature is set. When both temperatures are
displayed, the temperature for both the driver and
passenger are set. Pressing PASS. will turn the
passenger temperature setting on and off. If only the
driver temperature is set, the driver temperature is used
for the passenger and the passenger display is off.
9(Fan):Turn the fan knob clockwise to increase the
fan speed and counterclockwise to decrease the fan
speed. Turning the fan knob cancels the automatic fan
operation and places the system in manual. Turn the
knob to AUTO to return to automatic fan operation. If the
airow seems low when the fan is at the highest setting,
the passenger compartment air lter, if equipped, may
need to be replaced. SeePassenger Compartment Air
Filter on page 3-33for additional information.
9(Off):Turning the fan knob off will turn the
controller completely off. Only the rear defog and heated
seats will function when the fan knob is off.

Air Flow:This control has several settings to control
the direction of airow.
To change the current mode, select one of the following:
AUTO:This mode is automatically set depending on
the temperature in the vehicle and solar sensor
information.
H(Vent):This mode directs air to the instrument
panel outlets.
%(Bi-Level):This mode directs airow to the
instrument panel outlets and to the oor outlets. A small
amount of air is also directed to the windshield and
the side window outlets.
6(Floor):This mode directs most of the air to the
oor outlets with some air directed to the side window
outlets, and a little air directed to the windshield.
#(Air Conditioning):Press this button to turn the
air conditioning compressor on or off. The indicator light
on the button will come on when the air conditioning
is on.
?(Recirculation):Press this button to turn the
recirculation mode on or off. This mode keeps outside
air from coming in the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or to
help cool the air inside your vehicle more quickly.Recirculation is not available in defrost or
oor/defog mode.
Using recirculation for long periods of time may cause
the air inside your vehicle to become too dry. To prevent
this from happening, after the air in your vehicle has
cooled, turn the recirculation mode off.
z(Heated Seats):Press this button to turn the
heated seats on and off. The button on the left controls
the driver’s seat and the button on the right controls
the passenger’s seat. SeeHeated Seats on page 1-4for
additional information.
Sensors
The solar sensor on your vehicle monitors the solar
radiation and the air inside of your vehicle, then uses the
information to maintain the selected temperature by
initiating needed adjustments to the temperature, the fan
speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing the
sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located in the
center of the instrument panel, near the windshield,
or the system will not work properly.

Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for several seconds to remind occupants to
fasten their safety belts.
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 indicates if there is an electrical problem.
The system check includes the airbag sensors,
the airbag modules, the wiring, and the diagnostic
module. For more information on the airbag system,
seeAirbag System on page 1-48.
This light will come on
when the vehicle is
started, and it will ash for
a few seconds. Then
the light should go out.
This means the system is
functioning properly.
If the airbag readiness light stays on after the vehicle is
started, or comes on as the vehicle is being driven,
the airbag system may not work properly. Have
the vehicle serviced right away.
