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 10 to 16 mph (18 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.
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.
Your vehicle may or may not have a side impact airbag.
SeeAirbag System on page 1-47. 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

Headlamps on Reminder
If you open the driver’s door while leaving the
headlamps or parking lamps on and the key is in OFF,
you will hear a warning chime.
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.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL and
Twilight Sentinel
®, so be sure it is not covered. The DRL
system will make your low-beam headlamps come on
at a reduced brightness. In order for the DRL system to
be activated, the following conditions must be met:
The ignition is on.
The exterior lamp control is off.
The transaxle is not in PARK (P).When the DRL are on, only your low-beam headlamps
will be on at reduced intensity. The taillamps,
sidemarker and other lamps will not be on. Your
instrument panel will not be lit either.
When it is dark enough outside, your regular intensity
headlamps will come on at full brightness and the
DRL lighting will turn off. The parking lamps that
normally come on with your headlamps will also come
on. When it is bright enough outside, the regular
intensity headlamps and parking lamps will turn back
off, and the reduced brightness DRL lighting will
turn back on.
To idle your vehicle during the day with the DRL off,
shift the transaxle into PARK (P). The DRL will stay off
until you shift out of PARK (P).
At night, you can turn off all exterior lamps when you
are in PARK (P) by turning the Twilight Sentinel
®knob
all the way to OFF.
If the knob was already in OFF, it must be cycled to ON
and back to OFF. Turn the knob clockwise to turn the
exterior lighting back on. The lamps will come back
on automatically when you put the transaxle in gear.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Automatic Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic):Press the AUTO button for
automatic control of the inside temperature, the air
delivery mode and the fan speed.
1. Press the AUTO button. Whenever this button is
pressed, the display will show the current settings
for ve seconds before returning the display to
the exterior temperature.2. Adjust the temperature to 75° F (24° C).
Choosing the coldest or warmest temperature
setting will not cause the system to cool or heat any
faster. If you set the system at the coldest or
warmest temperature setting, the system will remain
at the maximum cold or hot setting and fan speed.
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.

If you are in city traffic, and your vehicle is stopped and
idling, or the weather is hot, the system may switch
from the OUTSIDE AIR mode to the recirculation mode.
To prevent the air inside of your vehicle from becoming
too stale, be sure to return to the outside air mode
periodically.
?RECIRC (Recirculation):Press this button to
limit the amount of outside air coming into the vehicle.
It can be used to prevent outside air and odors from
entering your vehicle or to help heat or cool the
air inside your vehicle more quickly. Press this button to
turn the recirculation mode on or off. When the button
is pressed, an indicator light will come on. The
recirculation mode cannot be used with the FRONT
defrost mode.
#A/C (Air Conditioning):Press this button to
override the automatic system and turn the air
conditioning system on or off. When A/C is pressed, an
indicator light in the button will come on to let you
know that it is activated. When in AUTO, the air
conditioning compressor will come on automatically, as
necessary. The air conditioning compressor will also
run when you select the FRONT defrost mode and
outside temperatures are above freezing.On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days, press the AUTO
button and the system will automatically enter
recirculation mode and the temperature will be at the full
cold position for maximum cooling.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.
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.

There is also an EXT (exterior) temperature sensor
located behind the front grill. This sensor reads
the outside air temperature and helps to maintain the
temperature inside the vehicle. Any cover on the front of
the vehicle could cause a false reading in the
temperature.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity,
or moisture, condensing on the cool window glass.
This can be minimized if the climate control system is
used properly. There are two modes to clear fog or frost
from your windshield. Use the defog mode to clear
the windows of fog or moisture and warm the
passengers. Use the FRONT defrost mode to remove
fog or frost from the windshield more quickly.
Press the MODE button until DEFOG appears to select
this function. Press the FRONT button to select the
defrost function.
DEFOG:This mode directs the air equally between the
windshield and the oor outlets.
1FRONT (Defrost):Pressing this button directs
most of the air to the windshield and the outboard outlets
for the side windows, with some air directed to the
oor outlets. When you select this mode, the system
turns off recirculation and runs the air conditioning
compressor unless the outside temperature is ator below freezing. The recirculation mode cannot be
selected while in the FRONT defrost mode. Do not drive
the vehicle until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
=REAR:Press this button to turn the rear window
defogger on or off. Be sure to clear as much snow from
the rear window as possible.
The rear window defogger will turn off about 10 minutes
after the button is pressed. If turned on again, the
defogger will only run for about ve minutes before
turning off. If you maintain a speed above 30 mph
(48 km/h), the rear defogger will not turn off
automatically to help keep the rear glass clear. The
defogger can also be turned off by pressing the button
again or by turning off the engine.
If your vehicle has outside heated mirrors, the mirrors
will heat to help clear fog or frost from the surface of the
mirror when the rear window defogger button is
pressed.
Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear
window defogger. Repairs would not be covered by
your warranty. Do not clear the inside of the rear
window with sharp objects.

Tachometer
The tachometer shows your engine speed in revolutions
per minute (rpm).
Safety Belt Reminder Light
When the key is turned to ON or START, a chime will
come on for several seconds to remind people to fasten
their safety belts.
The safety belt light will
also come on and stay on
for several seconds,
then ash for several more.
If the driver’s belt is already buckled, the light will come
on briey, but the chime will not sound.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows airbag or 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, seeAirbag System on page 1-47. V6 Engine
