Memory Seat and Mirrors
Your vehicle may have the memory package.
The controls for this feature are located on the
driver’s door panel, and are used to program and
recall memory settings for the driver’s seat and
the outside mirrors.
To save your positions in memory, do the
following:
1. Adjust the driver’s seat, including the seatback
recliner and lumbar, and both outside mirrors
to your preferred position.
2. Press and hold button 1 until two beeps
sound through the driver’s side front speaker
to let you know that the position has been
stored.
A second seating and mirror position can be
programmed by repeating the above steps and
pressing button 2 for a second driver.To recall your memory positions, the vehicle must
be in PARK (P). Press and release either
button 1 or button 2 corresponding to the desired
driving position. The seat and outside mirrors
will move to the position previously stored for the
identied driver. You will hear a single beep.
If you use the remote keyless entry transmitter to
enter your vehicle and the remote recall memory
feature is on, automatic seat and mirror movement
will occur. See “MEMORY SEAT RECALL”
underDIC Vehicle Customization on page 231for
more information.
To stop recall movement of the memory feature at
any time, press one of the power seat controls,
memory buttons, or power mirror buttons.
If something has blocked the driver’s seat while
recalling a memory position, the driver’s seat recall
may stop working. If this happens, press the
appropriate control for the area that is not recalling
for two seconds, after the obstruction is removed.
Then try recalling the memory position again
by pressing the appropriate memory button. If the
memory position is still not recalling, see your
dealer for service.

There may 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 prevent people from leaving the vehicle.
{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, and
turn the hazard warning ashers on when the
airbags inate. You can lock the doors, turn the
interior lamps off, and turn the hazard warning
ashers off by using the controls for those features.
In many crashes severe enough to inate the
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 an airbag inates, 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 471.
80

Let only qualied technicians work on the
airbag systems. Improper service can
mean that an airbag system will not work
properly. See your dealer for service.
Passenger Sensing System
Your vehicle has a passenger sensing system.
The passenger airbag status indicator on the
overhead console will be visible when you turn
your ignition key to RUN or START.
The words ON and OFF or the symbol for on and
off, will be visible during the system check.
When the system check is complete, either the
word ON or the word OFF, or the symbol for on or
the symbol for off will be visible. SeePassenger
Airbag Status Indicator on page 198.The passenger sensing system will turn off the
right front passenger’s frontal airbag and
seat-mounted side impact airbag under certain
conditions. The driver’s airbags are not part of the
passenger sensing system.
The passenger sensing system works with sensors
that are part of the right front passenger’s seat and
safety belt. The sensors are designed to detect the
presence of a properly-seated occupant and
determine if the right front passenger’s frontal
airbag and seat-mounted side impact airbag should
be enabled (may inate) or not.
Accident statistics show that children are safer if
they are restrained in the rear rather than the front
seat. We recommend that child restraints be
secured in a rear seat, including an infant riding in
a rear-facing infant seat, a child riding in a
forward-facing child seat and an older child riding
in a booster seat.

{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something
may 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. See
Airbag Readiness Light on page 197for
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 87for 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.
85

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 478.
{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.
86

One key is used for the
ignition, the driver’s door
and the glovebox lock.
When a new vehicle is delivered, the dealer
removes the key tag from the key and gives it to the
rst owner. Each tag has a code on it that tells your
dealer or a qualied locksmith how to make extra
keys. Keep the tag in a safe place. If you lose your
key, you will be able to have a new one made easily
using the tag.
If you need a new key, contact your dealer who
can obtain the correct key code. SeeRoadside
Assistance Program on page 466for more
information.
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.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.
94

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” under
Remote Keyless Entry (RKE) System
Operation on page 95.
If you are still having trouble, see your dealer or
a qualied technician for service.
Remote Keyless Entry (RKE)
System Operation
The vehicle’s doors can be locked and unlocked,
and the trunk can be unlatched from about
3 feet (1 m) up to 60 feet (18 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.
Your RKE transmitter, with the remote start button,
provides an increased range of 195 feet (60 m)
away. 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 (RKE) System on page 94.
