What Will You See After an Airbag
Inates?
After a frontal airbag inates, it quickly deates, so
quickly that some people may not even realize the
airbag inated. Roof-mounted rollover airbags
deate more slowly and may still be at least partially
inated minutes after the vehicle comes to rest.
Some components of the airbag module may be hot
for a short time. These components include the
steering wheel hub for the driver’s frontal airbag
and the instrument panel for the right front
passenger’s frontal airbag. For vehicles with
roof-mounted rollover airbags, the ceiling of your
vehicle near the side windows may be hot. 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
deated airbags. Airbag ination does not prevent
the driver from seeing out of the windshield or being
able to steer the vehicle, nor does it stop people
from leaving the vehicle.
{CAUTION:
When an airbag inates, 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 cannot
get out of the vehicle after an airbag
inates, 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.
Your vehicle has a feature that may automatically
unlock the doors and turn the interior lamps on
when the airbags inate (if battery power is
available). You can lock the doors again and turn
the interior lamps off by using the door lock
and interior lamp controls.

Aftermarket equipment, such as seat covers,
can affect how well the passenger sensing system
operates. You may want to consider not using
seat covers or other aftermarket equipment if your
vehicle has the passenger sensing system. See
Adding Equipment to Your Airbag-Equipped
Vehicle on page 105for more information about
modications that can affect how the system
operates.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat
cushion and seatback may interfere with
the proper operation of the passenger
sensing system.
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 do not want the system to inate 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 590.
{CAUTION:
For up to 10 seconds after the ignition key
is turned off and the battery is
disconnected, an airbag can still inate
during improper service. You can be
injured if you are close to an airbag when
it inates. Avoid 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 qualied to do so.
The airbag system does not need regular
maintenance.
104

At times you may notice a decrease in operating
range. This is normal for any remote keyless entry
system. If the transmitter does not work or if you
have to stand closer to your vehicle for the
transmitter to work, try this:
Check the distance. You may be too far from
your vehicle. You may need to stand closer
during rainy or snowy weather.
Check the location. Other vehicles or objects
may be blocking the signal. Take a few steps
to the left or right, hold the transmitter
higher, and try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 113.
If you are still having trouble, see your dealer or
a qualied technician for service.
Remote Keyless Entry System
Operation
The vehicle’s doors can be locked and unlocked
from about 3 feet (1 m) up to 65 feet (20 m)
away with the Remote Keyless Entry (RKE)
transmitter.
If your vehicle has the remote start feature you can
also start your vehicle with the RKE transmitter.
The RKE transmitter, with the remote start button,
provides an increased operating range of 195 feet
(60 m) away. However, the operating range may be
less while the vehicle is running. As a result, you
may need to be closer to your vehicle to turn it off
than you were to start it.
There are other conditions which can affect the
performance of the transmitter. SeeRemote
Keyless Entry System on page 112.
113

Battery Replacement
Under normal use, the battery in your RKE
transmitter should last about four years.
You can tell the battery is weak if the transmitter
will not work at the normal range in any location.
If you have to get close to your vehicle before
the transmitter works, it is probably time to change
the battery.
The REPLACE BATTERY IN REMOTE KEY
message in the vehicle’s DIC will display if the
RKE transmitter battery is low. See “REPLACE
BATTERY IN REMOTE KEY” underDIC Warnings
and Messages on page 254for additional
information.
Notice:When replacing the battery, use care
not to touch any of the circuitry. Static
from your body transferred to these surfaces
may damage the transmitter.To replace the battery in the RKE transmitter do
the following:
1. Use a at object with a thin edge into the
notch, located below the trunk release
button, and separate the bottom half from the
top half of the transmitter.
2. Remove the old battery, but do not use a
metal object to do this.
116

3. Slide the new battery into the transmitter with
the positive side of the battery facing down.
Use a type CR2032 battery, or equivalent
type. Make sure the cover is on tightly,
so water will not get in.
4. Snap the front and the back of the transmitter
together.
5. Test the operation of the transmitter with the
vehicle.
Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine
from outside of the vehicle. It may also start up
the vehicle’s heating or air conditioning systems
and rear window defogger. Normal operation of the
system will return after the key is turned to the
RUN position.
If your vehicle has an automatic climate control
system, during remote start, the climate control
system will default to a heating mode during colder
outside temperatures and a cooling mode during
warmer outside temperatures. If your vehicle
does not have an automatic climate controlsystem, during remote start the climate control
system will turn on at the setting the vehicle was
set to when the vehicle was last turned off.
Laws in some communities may restrict the use of
remote starters. For example, some laws may
require a person using the remote start to have the
vehicle in view when doing so. Check local
regulations for any requirements on remote starting
of vehicles.
Do not use the remote start feature if your vehicle
is low on fuel. Your vehicle may run out of fuel.
The keyless entry transmitter with the remote start
button, provides an increased range of operation.
However, the range may be less while the
vehicle is running. As a result, you may need to
be closer to your vehicle to turn it off, than
you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote
Keyless Entry System on page 112for additional
information.
/(Remote Start):Press and release the lock
button and then press and hold the remote
start button to start the vehicle.

To unlock the liftgate, use the power door lock
switch or press the door unlock button on
the Remote Keyless Entry (RKE) transmitter twice.
SeeRemote Keyless Entry System Operation
on page 113.
To open the liftglass, press the button on the
underside of the license pocket applique (A).
The liftglass can also be opened by pressing the
liftglass release button on the RKE.To open the entire liftgate, press the touchpad
on the underside of the liftgate handle (B).
The vehicle must be in PARK (P) to open the
liftgate. To close the liftgate, use the pull cup or
pull strap as an aid.
The liftgate or liftglass cannot be opened if the
rear wipers are in motion. Attempting to open the
liftgate or liftglass while the rear wipers are in
motion will cause the release of the liftglass
or liftgate to delay until the wipers are moved off
the liftglass.
Both the liftglass and liftgate have an electric
latch. If the battery is disconnected or has
low voltage, the liftglass and liftgate will not open.
The liftglass and liftgate will resume operation
when the battery is reconnected and charged.

under extreme high or low temperatures.
If this occurs, the liftgate can still be operated
manually. The power liftgate may not operate
under low battery conditions.If you shift the transmission out of PARK (P) while
the power function is in progress, the liftgate
power function will continue to completion. If you
shift the transmission out of PARK (P) and
accelerate before the power liftgate latches closed,
the liftgate may reverse to the open position.
Cargo could fall out of the vehicle. Always make
sure the power liftgate is closed and latched before
you drive away.
If you power open the liftgate and the liftgate
support struts have lost pressure, the lights will
ash and a chime will sound. The liftgate will hold
open temporarily, then slowly close. See your
dealer for service before using the liftgate.

It is not recommended that you drive with the
liftgate open, however, if you must drive with the
liftgate open, the power liftgate should be switched
to manual liftgate operation — the overhead
console switch set to the “Disable” position.
Both the liftglass and liftgate have an electric latch.
If the battery is disconnected or has low voltage,
the liftglass and liftgate will not open. The
liftglass and liftgate will resume operation when
the battery is reconnected and charged.
If the battery is properly connected and has
adequate voltage, and the liftgate or liftglass still
will not function, your vehicle should be taken to a
dealership for service.
{CAUTION:
It can be dangerous to drive with the
liftglass or liftgate open because carbon
monoxide (CO) gas can come into your
vehicle. You cannot see or smell CO.
It can cause unconsciousness and even
death.
CAUTION: (Continued)
CAUTION: (Continued)
If you must drive with the liftglass or
liftgate open, or if electrical wiring or
other cable connections must pass
through the seal between the body and
the liftglass or liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
with the recirculation mode off. That
will force outside air into your vehicle.
SeeClimate Control System on
page 210orDual Automatic Climate
Control System on page 213.
If you have air outlets on or under the
instrument panel, open them all
the way.
If your vehicle has a power liftgate,
disable the power liftgate function.
SeeEngine Exhaust on page 155.

If a door is opened without using the RKE
transmitter, a ten second pre-alarm will occur.
The horn will chirp and the lights will ash. If the
key is not placed in the ignition and turned to
START or the door is not unlocked by pressing the
unlock button on the RKE transmitter during the
ten second pre-alarm, the alarm will go off.
Your vehicle’s headlamps will ash and the horn
will sound for about two minutes, then will turn
off to save the battery power.
The theft-deterrent system will not activate if you
lock the doors with a key, the manual door lock, or
the power door lock switch. It activates only if you
use the RKE transmitter. You should also
remember that you can start your vehicle with the
correct ignition key if the alarm has been set off.
Here is how to avoid setting off the alarm by
accident:
If you do not want to activate the
theft-deterrent system, the vehicle should be
locked with the door key after the doors
are closed.
Always unlock a door with the RKE transmitter.
Unlocking a door any other way will set off the
alarm if the system has been armed.If you set off the alarm by accident, turn off the
alarm by pressing unlock on the RKE transmitter or
by placing the key in the ignition and turning it
to START.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s
window and open the driver’s door.
2. Activate the system by locking the doors with
the RKE transmitter.
3. Get out of the vehicle, close the door and wait
for the security light to go out.
4. Then reach in through the window, unlock the
door with the manual door lock and open the
door. This should set off the alarm.
If the alarm does not sound when it should, but
the vehicle’s headlamps ash, check to see if the
horn works. The horn fuse may be blown. To
replace the fuse, seeFuses and Circuit Breakers
on page 540.
If the alarm does not sound or the vehicle’s
headlamps do not ash, see your dealer for
service.

Ignition Positions
Use the key to turn the ignition switch to four
different positions.
A (LOCK):This position locks the ignition and
transmission. It is a theft-deterrent feature. You will
only be able to remove the 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.
B (ACCESSORY):This position lets you use
things like the radio and the windshield wipers
when the engine is off.
Notice:Lengthy operation of features such as
the radio in the accessory ignition position
and the RUN 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.
C (RUN):This is the position for driving. It is the
position the switch returns to after the engine
starts, and you release the key.
D (START):This position starts the engine.
