A second seating and mirror position can be
programmed by repeating the above steps and
pressing button 2.
To recall the 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. You will hear a
single beep.
If you use the Remote Keyless Entry (RKE)
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
(With DIC Buttons) on page 255for 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 being recalled, see
your dealer/retailer 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 exit position can
be recalled by pressing the exit button. You will
hear a single beep. The driver’s seat will
move back.
If the easy exit seat feature is on 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 255for more information.
Further programming for the memory seat feature
can be done using the DIC. You can select or
cancel the following:
The automatic easy exit seat feature.
The remote memory seat recall feature.
For programming information, seeDIC Vehicle
Customization (With DIC Buttons) on page 255.

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 Recording and
Privacy on page 536andEvent Data
Recorders on page 537.
Let only qualied technicians work on the
airbag systems. Improper service can
mean that an airbag system will not work
properly. See your dealer/retailer for service.
Passenger Sensing System
Your vehicle has a passenger sensing system
for the right front passenger’s position. The
passenger airbag status indicator will be visible
when you start your vehicle in the instrument
panel.
The words ON and OFF, or the symbol for on and
off, will be visible during the system check. If
you are using remote start to start your vehicle
from a distance, if equipped, you may not see 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 218.

Safety belts help keep the passenger in position
on the seat during vehicle maneuvers and braking,
which helps the passenger sensing system
maintain the passenger airbag status. See “Safety
Belts” and “Child Restraints” in the Index for
additional information about the importance of
proper restraint use.
{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 airbag(s). SeeAirbag
Readiness Light on page 217for more on
this, including important safety
information.
A thick layer of additional material, such as a
blanket or cushion, or aftermarket equipment such
as seat covers, seat heaters, and seat massagers
can affect how well the passenger sensing
system operates.
89

You may want to consider not using seat covers
or other aftermarket equipment. SeeAdding
Equipment to Your Airbag-Equipped Vehicle on
page 91for 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/retailerand the service manual have information about
servicing your vehicle and the airbag system.
To purchase a service manual, seeService
Publications Ordering Information on page 535.
{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.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the
exterior of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height,
front end or side sheet metal, they may keep
the airbag system from working properly.
Also, the airbag system may not work properly
if you relocate any of the airbag sensors. If
you have any questions about this, you should
contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in
Step Two of the Customer Satisfaction
Procedure in this manual. See Customer
Satisfaction Procedure.
If your vehicle has rollover roof-rail airbags,
seeDifferent Size Tires and Wheels on
page 452for additional important information.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel,
instrument panel, roof-rail airbag modules,
ceiling headliner, and pillar garnish trim, side
impact sensors, rollover sensor module,
or airbag wiring can affect the operation of the
airbag system. If you have questions, call
Customer Assistance. The phone numbers
and addresses for Customer Assistance are in
Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 518.
Your dealer/retailer and the service manual have
information about the location of the airbag
sensors, sensing and diagnostic module and
airbag wiring.

Restraint System Check
Checking the Restraint Systems
Safety Belts
Now and then, make sure the safety belt reminder
light and all your belts, buckles, latch plates,
retractors, and anchorages are working properly.
SeeSafety Belt Reminder Light on page 216
for more information.
Look for any other loose or damaged safety belt
system parts. If you see anything that might keep a
safety belt system from doing its job, have it
repaired. Keep safety belts clean and dry. See
Care of Safety Belts on page 482for more
information.
Torn or frayed safety belts may not protect you in
a crash. They can rip apart under impact forces.
If a belt is torn or frayed, get a new one right away.
Airbag System
The airbag system does not need regularly
scheduled maintenance or replacement. Make
sure the airbag readiness light is working.
SeeAirbag Readiness Light on page 217for more
information.
Notice:If an airbag covering is damaged,
opened, or broken, the airbag may not work
properly. Do not open or break the airbag
coverings. If there are any opened or broken
airbag covers, have the airbag covering and/or
airbag module replaced. For the location of
the airbag modules, seeWhat Makes an Airbag
Inflate? on page 83. See your dealer/retailer
for service.
