How does an air bag restrain?
In moderate to severe frontal or near
-frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. Air bags supplement the protection
provided by safety belts. Air bags distribute the force of
the impact more evenly over the occupant's upper body,
stopping the occupant more gradually. But air bags
would not help you in many types of collisions, including
rollovers, rear impacts and side impacts, primarily because
an occupant's motion is not toward those air bags.
Air bags should never be regarded as anything more than
a supplement to safety belts, and then only in moderate
to severe frontal or near
-frontal collisions.
What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates, so quickly
that some people may not even realize the air bag
inflated. Some components of the air bag module
-- the
steering wheel hub for the driver's air bag, or the
instrument panel for the right front passenger's
bag
-- will be hot for a short time. The parts of the bag
that come into contact with you may be warm, but not
too hot to touch. There will be some smoke and dust
coming from vents in the deflated air bags. Air bag
inflation doesn't prevent the driver from seeing or from
being able to steer the vehicle, nor does it stop people
from leaving the vehicle.
CAUTION:
When an air bag inflates, there is dust in the air.
This dust could cause breathing problems for
people with a history of asthma or other
breathing trouble. To avoid this, everyone in the
vehicle should get out as soon as it is safe to do so.
If you have breathing problems but can't get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window or door.

Air bags are designed to inflate only once. After they
inflate, 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 a diagnostic module,
which records information about the air bag system.
The module records information about the readiness
of the system, when the system commands air bag
inflation and driver's safety belt usage at deployment.

2-9 Programmable Automatic Door Locks
(If Equipped)
If your vehicle has power door locks, it is equipped with a
feature that enables you to program your power door locks.
The following is a list of the available programming options:

All doors lock/Only the driver's door unlocks:
Press the lock side of the power lock switch on the
door panel once and then the unlock side once.
If your vehicle is not equipped with remote keyless
entry, you may not be able to utilize this option.

All doors lock/All doors unlock: Press the lock side
of the power lock switch on the door panel once, and
then the unlock side twice.

For more information, see your dealer.
Your vehicle left the factory programmed to have no
doors lock or unlock automatically. You can set the
automatic door lock feature to lock all the doors when
the vehicle speed is greater than 15 mph (24 km/h) fortwo seconds, and then unlock the door(s) once the key is
removed from the ignition. The following instructions
detail how to program your door locks. Choose one of
the previous programming options before entering the
programming mode.
To enter the program mode you need to do the following:
1. Begin with the ignition in OFF. Then pull the turn
signal/multifunction lever all the way toward you
and hold it while you perform the next step.
2. Turn your key to RUN and OFF twice. Then, with
the key in OFF, release the turn signal/multifunction
lever. Once you do this, you will hear the lock switch
lock and unlock.
3. You are now ready to program the automatic door
locks. Select one of the previous four programming
options and follow the instructions. You will have
30 seconds to begin programming. If you exceed the
30 second limit, the locks will automatically lock and
unlock to indicate you have left the program mode.
If this occurs, repeat the procedure beginning with
Step 1. You can exit the program mode any time by
turning the ignition to RUN (the locks will
automatically lock and unlock to indicate you are
leaving the program mode). If the lock/unlock switches
are not pressed while in the programming mode, the
auto lock/unlock setting will not be modified.

four times within six seconds (a chime will sound),
or when the ignition is turned off and on again.
As with any vehicle, you should turn on the regular
headlamp system when you need it.Fog Lamps (If Equipped)
Use your fog lamps for better vision in foggy or misty
conditions. Your parking lamps or low
-beam headlamps
must be on for your fog lamps to work.
The fog lamp switch is on the instrument panel under
the headlamps knob. Press the switch to turn the fog
lamps on. Press the switch again to turn them off. A
light will glow in the switch when the fog lamps are on.
The fog lamps will go off whenever your high

US/MET: The US/MET (United States/metric) button
allows you to switch the display between the English
and metric system.
MODE: The MODE button can be used to toggle
between three modes of operation: OFF, COMP/TEMP
and TRIP.
COMP/TEMP: The display provides the outside
temperature and one of eight compass readings to
indicate the direction the vehicle is facing.
Before you turn on the ignition and move the vehicle,
the temperature indicated will be the last outside
temperature recorded with the ignition on. If the outside
temperature is 37
F (3
C) or lower, the display will
toggle between the word ICE and the current
temperature every eight seconds. This is a warning to
the driver that road conditions may be icy, and that
appropriate precautions should be taken.

The compass is self-calibrating, so it does not need
to be manually set. However, if ªCº (Calibration) is
displayed, the compass will need to be calibrated. You
may also place the compass in a noncalibrated mode by
pressing and holding the MODE and US/MET buttons
simultaneously while in the COMP/TEMP mode. After
about 10 seconds, the compass will display C and you
can release the buttons. Drive the vehicle in a complete
360
circle three times at a speed of less than 5 mph
(8 km/h), and the compass will function normally.
Once the calibration is complete, the display will return
to a compass reading.
Variance is the difference between magnetic north and
geographic north. In some areas, the difference between
the two can be great enough to cause false compass
readings. If this happens, follow these instructions to set
the variance for your particular location:
1. Find your location on the zone map earlier in this
section. Record your zone number.
2. Press and hold both the MODE and the US/MET
buttons in the COMP/TEMP mode.
3. After five seconds, the compass will acknowledge
the variation mode by displaying the current zone
number. When it does, release both buttons.
4. Press US/MET until your zone number appears on
the display.5. Press MODE to enter your zone number.
Your variance is now set and the display will
return to the COMP/TEMP mode.
TRIP: Once in the TRIP mode, pressing the
MODE button will step you through the following
TRIP functions:

AVG ECON: The average fuel economy since the
last reset is displayed.

INST ECON: Instantaneous fuel economy for the
last second of driving is displayed.

RANGE: The display indicates the estimated
distance that can be travelled with the remaining fuel
in the tank, based on the fuel economy for the last
few hours of driving.

FUEL USED: The fuel used since the last reset
is displayed.

AVG SPEED: The average speed since the last reset
is displayed.
To reset the trip computer, press the MODE and
US/MET buttons simultaneously for at least two
seconds. All functions will be displayed briefly once
the system is reset. Reset can only be performed in the
AVG ECON, FUEL USED and AVG SPEED modes.
All three modes are reset simultaneously.

You can direct the airflow side-to-side by moving the
thumbwheel located in the center of the vent. The vent
can be tilted up and down also. To control the amount of
airflow through the outlets, move the thumbwheel below
the vent.
Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.

When you enter a vehicle in cold weather, turn the
fan control to high for a few moments before driving
off. This helps clear the intake ducts of snow and
moisture, and reduces the chance of fogging the
inside of your windows.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.Audio Systems
