Memory Seat, Mirrors, and Pedals
If your vehicle has this
feature, the controls for
the memory function
are located on the
driver’s door.
These buttons are used to program and recall
memory settings for the driver’s seating position,
both outside mirror positions, and the adjustable
pedals, if equipped. The settings for these features
can be saved for up to two drivers.
To store the memory settings, do the following:
1. Adjust the driver’s seat, including the seatback
recliner and lumbar, both of the outside
mirrors, and the adjustable pedals, if
equipped, to the desired position.
SeeAdjustable Throttle and Brake Pedal
on page 116for more information.2. Press and hold the 1 or 2 button of the
memory control for three seconds. A
double chime will sound to let you know
that the position has been stored.
To repeat the procedure for a second driver,
follow the preceding steps, but press the other
numbered memory control button.
To recall the memory settings, do one of the
following:
Press and release button 1 or 2 while the
vehicle is in PARK (P). A single chime
will sound and the memory position will be
recalled.
If programmed to do so through the Driver
Information Center (DIC), pressing the
unlock button on the remote keyless entry
transmitter will recall the preset driver’s
memory seat, mirrors, and adjustable pedals
position. The numbers on the back of the
transmitters, 1 or 2, correspond to the numbers
on the memory controls.
If programmed to do so through the DIC,
placing the key in the ignition will recall
the driver’s memory seat, mirrors, and
adjustable pedals positions.
12
See “Seat Recall” underDIC Vehicle
Customization on page 229for more information.
To stop recall movement of the memory seat
feature at any time, press one of the memory
buttons or power seat controls.
Easy Exit Seat
The control for the easy exit seat function is
located on the driver’s door below the memory
buttons 1 and 2. The easy exit seat button is used
to program and recall the desired driver’s seat
position when exiting or entering the vehicle. The
mirrors, power lumbar, recline, and adjustable
pedals, if equipped, positions will not be stored or
recalled when using the easy exit seat function.
The seat position can be saved for up to
two drivers.
To store the easy exit seat position, do the
following:
1. Press and release the 1 or 2 button of the
memory control for less than three seconds.
The seat will move to the stored memory
position.
2. Adjust the seat to the desired exit position.3. Press and hold the easy exit seat button for
more than three seconds. A double chime will
sound to let you know that the position has
been stored for the selected button 1 or 2.
To repeat the procedure for a second driver,
follow the preceding steps, but press the other
numbered memory control button.
To recall the easy exit seat position, do one of the
following:
Press the easy exit seat button on the
memory control while the vehicle is in
PARK (P). The seat will move to the stored
exit position.
Or, if the easy exit seat feature is activated in
the Driver Information Center (DIC), removing
the key from the ignition will move the seat
to the exit position. See “Easy Exit Seat” under
DIC Vehicle Customization on page 229for
more information on activating this feature in
the DIC.
If an easy exit seat position has not been stored,
the default position is all the way rearward.

Passenger Sensing System
Your vehicle has a passenger sensing system for
the right front passenger’s position. A passenger
airbag status indicator in the rearview mirror will
be visible when you turn your ignition key to
START or RUN.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 202.
The passenger sensing system will turn off
the right front passenger’s frontal 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 passenger’s frontal
airbag should be enabled (may in ate) 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.
United States
Canada

The passenger sensing system is designed to turn
off the right front passenger’s frontal airbag if:
The right front passenger seat is unoccupied.
The system determines that an infant is
present in a rear-facing infant seat.
The system determines that a small child is
present in a forward-facing child restraint.
The system determines that a small child is
present in a booster seat.
A right front passenger takes his/her weight off
of the seat for a period of time.
The right front passenger seat is occupied by
a smaller person, such as a child who has
outgrown child restraints.
Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned
off the passenger’s frontal airbag, the off indicator
in the rearview mirror will light and stay lit to
remind you that the airbag is off.If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove
the child restraint from the vehicle and reinstall
the child restraint following the child restraint
manufacturer’s directions and refer toSecuring a
Child Restraint in the Right Front Seat Position
on page 66.
If, after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to
make sure that the vehicle’s seatback is not
pressing the child restraint into the seat cushion.
If this happens, slightly recline the vehicle’s
seatback and adjust the seat cushion if possible.
Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head restraint.
If the on indicator is still lit, secure the child
in the child restraint in a rear seat position in
the vehicle and check with your dealer.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides 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.
SeeCustomer Satisfaction Procedure
on page 526.
Q:Because I have a disability, I have to get
my vehicle modi ed. 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, the inside review mirror,
ceiling headliner, ceiling and pillar garnish trim,
roof-mounted airbag modules, 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 526.
