CAUTION: (Continued)
can guarantee that an airbag will not
deploy under some unusual circumstance,
even though it is turned off. We
recommend that rear-facing child
restraints be secured in the rear seat,
even if the airbag is off.
If you secure a forward-facing child
restraint in the right front seat, always
move the front passenger seat as far back
as it will go. It is better to secure the child
restraint in a rear seat.
{CAUTION:
If the airbag readiness light ever comes
on when you have turned off the airbag, it
means that something may be wrong with
the airbag system. The right front
passenger’s airbag could inate even
though the switch is off. If this ever
happens, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing
child restraint in the right front
passenger’s seat) until you have your
vehicle serviced. SeeAirbag Off Switch on
page 84andAirbag Readiness Light on
page 207for more on this, including
important safety information.
73

In many crashes severe enough to inate an
airbag, windshields are broken by vehicle
deformation. Additional windshield breakage
may also occur from the right front
passenger airbag.
Airbags are designed to inate only once.
After they inate, you will need some new
parts for the 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 has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Collection and
Event Data Recorders on page 546.
Let only qualied technicians work on the
airbag system. Improper service can mean that
an airbag system will not work properly. See
your dealer for service.
Airbag Off Switch
Your vehicle has a switch on the instrument panel
that you can use to turn off the right front
passenger’s airbag.

again, insert your ignition key into the switch, push
in, and move the switch to the on position.

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 553.
{CAUTION:
For up to 10 seconds, after the ignition 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.
88

Your vehicle has
one double-sided key
for the ignition and
all door locks.
If you ever lose your keys, your dealer will be able
to assist you with obtaining replacements.
In an emergency contact roadside assistance. See
Roadside Assistance Program on page 542.Remote Keyless Entry (RKE)
System
Your Remote Keyless Entry (RKE) system
operates on a radio frequency subject to Federal
Communications Commission (FCC) Rules
and with Industry Canada.
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
1. This device may not cause interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
This device complies with RSS-210 of Industry
Canada. Operation is subject to the following
two conditions:
1. This device may not cause interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.
96

At times you may notice a decrease in operating
range. This is normal for any RKE 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”
underRemote Keyless Entry (RKE) System
Operation on page 97.
If you are still having trouble, see your dealer
or a qualied technician for service.
Remote Keyless Entry (RKE)
System Operation
You can lock and unlock your doors from about
3 feet (1 m) up to 100 feet (30 m) away using the
Remote Keyless Entry (RKE) transmitter
supplied with your vehicle.
K(Unlock):Press this
button once to unlock
the driver’s door.
The interior lamps will
come on. Pressing
unlock again within
three seconds will cause
the remaining doors
to unlock.
You can choose different feedback options for
each press of the unlock button. See “Lock
Feedback” and “Unlock Feedback” underDIC
Vehicle Customization on page 234for more
information.
97

To replace the battery in the RKE transmitter, do
the following:
1. Insert a thin object, such as a coin, in the slot
between the covers of the transmitter housing
near the key ring hole. Remove the bottom
by twisting the coin.
2. Remove and replace the battery with a
three-volt CR2032 or equivalent battery,
positive (+) side up.3. Align the covers and snap them together.
4. Resynchronize the transmitter. See
“Resynchronization” following this information.
5. Check the operation of the transmitter.
Resynchronization
Resynchronization may be necessary due to the
security method used by this system. The
transmitter does not send the same signal twice to
the receiver. The receiver will not respond to a
signal that has been sent previously. This prevents
anyone from recording and playing back the
signal from the transmitter.
To resynchronize your transmitter, stand close to
your vehicle and press and hold the lock and
unlock buttons on the transmitter at the same time
for 15 seconds. The door locks should cycle to
conrm synchronization. If the locks do not cycle,
see your dealer for service.
