If something has blocked the driver’s seat and/or
the adjustable pedals while recalling a memory
position, the driver’s seat and/or the adjustable
pedals recall may stop working. If this happens,
remove the obstruction and press the appropriate
control for the area that is not responding for
two seconds. 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.
Easy Exit Seat
The control for this feature is located on the
driver’s door panel between buttons 1 and 2.
With the vehicle in PARK (P), the driver’s seat exit
position can be recalled by pressing the exit
button. You will hear a single beep, and the
driver’s seat will move back.
If the easy exit seat feature is programmed in the
Driver Information Center (DIC), automatic
seat movement will occur when the key is removed
from the ignition. See “EASY EXIT SEAT” under
DIC Vehicle Customization (With DIC Buttons)
on page 278for more information.The memory seat and easy exit features can also
be programmed using the DIC.
For programming information, seeDIC Vehicle
Customization (With DIC Buttons) on page 278.

{CAUTION:
You can lose control of the vehicle if
you try to adjust a manual driver’s seat
while the vehicle is moving. The sudden
movement could startle and confuse you,
or make you push a pedal when you do
not want to. Adjust the driver’s seat only
when the vehicle is not moving.

Your vehicle has a feature that may automatically
unlock the doors, turn the interior lamps on, and
ash the hazard warning ashers when the airbags
inate. You can lock the doors again, turn the
interior lamps off, and turn off the hazard warning
ashers 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 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 594.
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.
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. See
Passenger Airbag Status Indicator on page 243.

{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. SeeAirbag Readiness Light
on page 242for 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.
SeeAdding 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 600.
{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

Your vehicle has
one double-sided key
for the ignition, all
door locks, tailgate,
and side storage boxes.
If you ever lose your keys, your dealer will be
able to assist you with obtaining replacements.
In an emergency contact roadside assistance.
SeeRoadside Assistance Program on page 588
for more information.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”
underRemote 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
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 (RKE) System on page 94.

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 power door lock switch while the door is
open, or 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.
While the alarm is set, the power door unlock
switch is not operational.
If the alarm does not sound when it should but the
headlamps ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
seeInstrument Panel Fuse Block on page 548
andUnderhood Fuse Block on page 551.
If the alarm does not sound or the headlamps
do not ash, the vehicle should be serviced
by your dealer.
