There is an airbag readiness light on the instrument
panel, which shows AIR BAG or the airbag symbol.
The system checks the airbag electrical system
for malfunctions. The light tells you if there is an
electrical problem. SeeAirbag Readiness Light on
page 3-26for more information.
Where Are the Airbags?
The driver’s airbag is in the middle of the steering wheel. United States
Canada

The right front passenger’s airbag is in the instrument
panel on the passenger’s side.
{CAUTION:
If something is between an occupant and an
airbag, the bag might not in ate properly or it
might force the object into that person causing
severe injury or even death. The path of an
in ating 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.
When Should an Airbag In ate?
The driver’s and right front passenger’s frontal airbags
are designed to in ate in moderate to severe frontal
or near-frontal crashes. But they are designed to
in ate 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 in ate 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.
If the front of your vehicle goes straight into a wall that
does not move or deform, the threshold level is
about 9 to 16 mph (14 to 26 km/h). (The threshold level
can vary, however, with speci c vehicle design, so
that it can be somewhat above or below this range.)
Airbags may in ate at different crash speeds.
For example:
If the vehicle hits a stationary object, the airbag
could in ate at a different crash speed than if
the object were moving.
If the object deforms, the airbag could in ate 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 in ate 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 in ate 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 in ate during vehicle rollovers, rear
impacts, or in many side impacts because in ation
would not likely help the occupants.
In any particular crash, no one can say whether an
airbag should have in ated simply because of the
damage to a vehicle or because of what the repair
costs were. In ation is determined by the angle of the
impact and how quickly the vehicle slows down in frontal
or near-frontal impacts.
What Makes an Airbag In ate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. The
sensing system triggers a release of gas from the
in ator, which in ates the airbag. The in ator, airbag,
and related hardware are all part of the airbag modules
inside the steering wheel and in the instrument panel
in front of the right front passenger.

How Does an Airbag Restrain?
In moderate to severe frontal or near-frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. Airbags supplement the
protection provided by safety belts. Airbags distribute
the force of the impact more evenly over the occupant’s
upper body, stopping the occupant more gradually.
But airbags would not help you in many types of
collisions, including rollovers, rear impacts and many
side impacts, primarily because an occupant’s motion is
not toward those airbags. Airbags 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
Airbag In ates?
After an airbag in ates, it quickly de ates, so quickly that
some people may not even realize the airbag in ated.
Some components of the airbag module — the steering
wheel hub for the driver’s airbag, 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 the
vents in the de ated airbags. Airbag in ation does not
prevent the driver from seeing or being able to steer the
vehicle, nor does it stop people from leaving the vehicle.
{CAUTION:
When an airbag in ates, 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 not get out of the vehicle after an airbag
in ates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an airbag deployment,
you should seek medical attention.

Airbags are designed to in ate only once. After an
airbag in ates, you will need some new parts for
your airbag system. If you do not get them,
the airbag system will not be there to help protect
you in another crash. A new system will include
airbag modules and possibly other parts. The
service manual for your vehicle covers the need to
replace other parts.
Your vehicle is equipped with a crash sensing and
diagnostic module which records information after
a crash. SeeVehicle Data Collection and Event
Data Recorders on page 7-10.
Let only quali ed technicians work on your airbag
system. Improper service can mean that your
airbag system will not work properly. See your
dealer for service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, the bag
may not work properly. You may have to replace
the airbag module in the steering wheel or both
the airbag module and the instrument panel for
the right front passenger’s airbag. Do not open or
break the airbag coverings.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. You don’t want the system to in ate
while someone is working on your vehicle. Your dealer
and the service manual have information about servicing
your vehicle and the airbag system. To purchase a
service manual, seeService Publications Ordering
Information on page 7-12.
{CAUTION:
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an
airbag can still in ate during improper service.
You can be injured if you are close to an
airbag when it in ates. Avoid wires wrapped
with yellow tape or yellow connectors. They
are probably part of the airbag system. Be sure
to follow proper service procedures, and make
sure the person performing work for you is
quali ed to do so.
The airbag system does not need regular maintenance.

Ignition Positions
With the key in the ignition, you can turn it to
ve different positions.
A (ACCESSORY):This position lets you use things
like the radio, power windows and windshield wipers
when the engine is off. To get into ACCESSORY,
push in the key and turn it toward you.Notice:Lengthy operation of features such as the
radio in the accessory ignition position may drain the
battery and prevent your vehicle from starting. Do not
operate your vehicle in the accessory ignition
position for a long period of time.
B (LOCK):This position locks your ignition and
transmission. It is a theft-deterrent feature. You will
only be able to remove your key when the ignition is
turned to LOCK.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in.
If it is, turn the steering wheel left and right while
you turn the key hard. If none of this works,
then your vehicle needs service.
C (OFF):This position lets you turn off the engine.
Use OFF if you must have your vehicle in motion while
the engine is off (for example, if your vehicle is being
towed).
D (RUN):This is the position for driving.
E (START):This position starts your engine.

Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly.
Fuel Regulator
Your vehicle has a fuel regulator that shuts the fuel off
when the engine reaches 5,600 rpm.
Engine Coolant Heater
If your vehicle has this feature, in very cold weather,
0°F (−18°C) or colder, the engine coolant heater
can help. You will get easier starting and better fuel
economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
At temperatures above 32°F (0°C), use of the coolant
heater is not required. Your vehicle may also have
an internal thermostat in the plug end of the cord.
This will prevent operation of the engine coolant heater
when the temperature is at or above 0°F (−18°C) as
noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located on the
driver’s side of the engine compartment, near
the power steering uid reservoir.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could be
damaged.

All-Wheel Drive
If your vehicle has all-wheel drive, your engine’s driving
power is sent to all four wheels for extra traction
when needed.
This is like four-wheel drive, but there is no separate
lever or switch to engage or disengage the front axle.
It is fully automatic, and adjusts itself as needed for road
conditions.
You may experience a brief vehicle vibration upon
acceleration when driving in slippery conditions. This is
normal and is an indication that the all-wheel drive
system is functioning properly.
Parking Brake
To set the parking brake, hold the regular brake pedal
down with your right foot.
Push down the parking brake pedal with your left foot.
If the ignition is on, the brake system warning light
will come on.To release the parking brake, hold the regular brake
pedal down. Pull the brake release lever located on the
lower left side of the steering column.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on a hill, see
Towing a Trailer on page 4-34. That section shows
what to do rst to keep the trailer from moving.
