{CAUTION:
When an airbag inates, there may be
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, turn the interior lamps on
when the airbags inate and turn on the hazard
warning ashers. You can lock the doors, turn the
interior lamps off, and turn the hazard warning
ashers on by using the controls for those
features.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
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 has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Collection and
Event Data Recorders on page 537.
Let only qualied technicians work on your
airbag system. Improper service can mean that
an airbag system will not work properly. See
your dealer for service.
85

{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something may
CAUTION: (Continued)
CAUTION: (Continued)
be wrong with the airbag system. If this
ever happens, have the vehicle serviced
promptly, because an adult-size person
sitting in the right front passenger’s seat
may not have the protection of the frontal
airbag. SeeAirbag Readiness Light on
page 210for more on this, including
important safety information.
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 92for more information about
modications that can affect how the system
operates.
90

{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 544.
{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.
91

Your vehicle has the PASS-Key®III vehicle theft
system. The key has a transponder in the key
head that matches a decoder in the vehicle’s
steering column. If a replacement key or
any additional key is needed, you must purchase
this key from your dealer. The key will have PK3
stamped on it. Keep the bar code tag that came
with the original keys. Give this tag to your dealer if
you need a new key made.
Any new PASS-Key
®III key must be programmed
before it will start your vehicle. SeePASS-Key®
III on page 126for more information on
programming your new key.
Notice:If you ever lock your keys in your
vehicle, you may have to damage the vehicle
to get in. Be sure you have spare keys.
If you ever do get locked out of your vehicle, see
Roadside Assistance Program on page 532for
more information.
Remote Keyless Entry System
Your keyless entry 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.
98

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”
underRemote Keyless Entry System
Operation on page 99.
If you are still having trouble, see your dealer
or a qualied technician for service.
Remote Keyless Entry System
Operation
You can lock and unlock the vehicle’s doors and
the liftgate using the remote keyless entry
transmitter supplied with your vehicle.The remote keyless
entry transmitter shown
here is for a vehicle
equipped with the
remote vehicle start
feature and dual power
sliding doors.
The remote keyless entry transmitter supplied with
your vehicle will only contain the buttons specic
to your vehicle’s factory installed remote
system features.
/(Remote Vehicle Start):If your vehicle has
this feature, you can start the engine from outside
the vehicle. See “Remote Vehicle Start” at the
end of this section for more detailed information.

3. If the power sliding door overhead console
switch is in the override (deactivation)
position, return to the activation position.
4. Open the sliding door using the remote
keyless entry transmitter, overhead console
switch, or passenger switch. Allow the door to
travel fully open.
If the door does not travel to the fully open
position, press the overhead console switch to the
override (deactivation) position and slide the
door fully open and closed. Check for foreign
objects in the tracks. Repeat the procedure starting
with Step 1. If the door resists travel to the fully
open position, see your dealer for service.Liftgate
To unlock or lock the liftgate from the outside, use
the remote keyless entry transmitter. For more
information, seeRemote Keyless Entry System
Operation on page 99.
You can also use the power door lock switch to
lock and unlock the liftgate.
Open the liftgate using the handle located above
the license plate. Once slightly opened, the
liftgate will rise by itself. Lamps in the rear of the
vehicle will come on, illuminating the rear
cargo area.
Notice:If you open the liftgate without
checking for overhead obstructions such as a
garage door, you could break the liftgate
glass. Always check to make sure the area
above the liftgate is clear before opening it.
119

PASS-Key®III
Your PASS-Key®III 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 harmful
interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation.
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.PASS-Key
®III uses a radio frequency transponder
in the key that matches a decoder in your
vehicle.
PASS-Key®III Operation
Your vehicle is equipped
with the PASS-Key®III
(Personalized
Automotive Security
System) theft-deterrent
system. PASS-Key
®III
is a passive theft
deterrent system.
This means you do not have to do anything
different to arm or disarm the system. It works
when you insert or remove the key from the
ignition.
When the PASS-Key
®III system senses that
someone is using the wrong key, it shuts down the
vehicle’s starter and fuel systems.
126

The starter will not work and fuel will stop being
delivered to the engine. Anyone using a
trial-and-error method to start the vehicle will be
discouraged because of the high number of
electrical key codes.
If the engine does not start and the security
message comes on, the key may have a damaged
transponder. Turn the ignition off and try again.
If the engine still does not start, and the key
appears to be undamaged, try another ignition key.
At this time, you may also want to check the
instrument panel PASS KEY fuse. If the engine still
does not start with the other key, your vehicle
needs service. If your vehicle does start, the rst
key may be faulty. See your dealer or a locksmith
who can service the PASS-Key
®III to have a new
key made. SeeFuses and Circuit Breakers on
page 497.
It is possible for the PASS-Key
®III decoder to learn
the transponder value of a new or replacement key.
Up to 10 keys may be programmed for the vehicle.
This procedure is for learning additional keys only.
If all the currently programmed keys are lost or do
not operate, you must see your dealer or a
locksmith who can service PASS-Key
®III to have
keys made and programmed to the system.See your dealer or a locksmith who can service
PASS-Key
®III to get a new key blank that is
cut exactly as the ignition key that operates the
system.
To program the new key, do the following:
1. Verify the new key has PK3 stamped on it.
2. Insert the original, already programmed
key into the ignition lock cylinder and start the
engine. If the engine will not start, see your
dealer for service.
3. After the engine has started, turn the key to
LOCK and remove the key.
4. Insert the key to be programmed and turn it to
RUN within 10 seconds of removing the
previous key.
5. The security message will turn off once the
key has been programmed. It may not be
apparent that the security message went on
due to how quickly the key is programmed.
6. Repeat Steps 1 through 4 if additional keys
are to be programmed.
127

If you are ever driving and the security message
comes on and stays on, you will be able to restart
your engine if you turn it off. Your PASS-Key
®III
system, however, is not working properly and must
be serviced by your dealer. Your vehicle is not
protected by the PASS-Key
®III system at
this time.
If you lose or damage a PASS-Key
®III key, see
your dealer or a locksmith who can service
PASS-Key
®III to have a new key made.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an
elaborate break-in. But it will perform better in
the long run if you follow these guidelines:
Do not drive at any one constant speed,
fast or slow, for the rst 500 miles
(805 km). Do not make full-throttle starts.
Avoid downshifting to brake, or slow,
the vehicle.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
your new brake linings are not yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every time
you get new brake linings.
Do not tow a trailer during break-in. See
Towing a Trailer on page 386for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can
be gradually increased.
