To stop recall movement of the memory function
at any time, press one of the power seat controls,
memory buttons, power mirror buttons, or
adjustable pedal switch.
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 291for 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 291.

Here is why:
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Be sure the airbag is off
before using a rear-facing child restraint in
the right front seat position. If you secure a
forward-facing child restraint in the right
front seat, always move the right front
passenger seat as far back as it will go.
A rear seat is a safer place to secure a forward
facing child restraint. SeeWhere to Put the
Restraint on page 57. If you need to secure a
forward-facing child restraint in the right front seat
position, move the seat as far back as it will go
before securing a forward-facing child restraint.
SeeManual Seats on page 9orPower Seats on
page 10.
{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
when you have turned off the airbag, it
means that something may be wrong with
the airbag system. The right front
passenger’s airbag could inate even
though the switch is off. If this ever
happens, have the vehicle serviced
promptly. Until you have the vehicle
serviced, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing
child restraint in the right front passenger’s
seat). SeeAirbag Off Switch on page 95.
If your child restraint has the LATCH system, see
Lower Anchors and Tethers for Children (LATCH)
on page 60.
74

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 659.
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.
Airbag Off Switch
If one of the switches pictured in the following
illustrations is located in your glove box, your
vehicle has an airbag on-off switch that you can
use to manually turn on or off the right front
passenger’s airbag. Your switch may vary slightly.
If your vehicle does not have an airbag off switch,
it may have a passenger sensing system. See
Passenger Sensing System.

{CAUTION:
If the airbag readiness light ever comes
on when you have turned off the airbag, it
means that something may be wrong with
the airbag system. The right front
passenger’s airbag could inate even
though the switch is off. If this ever
happens, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing
child restraint in the right front
passenger’s seat) until you have your
vehicle serviced. SeeAirbag Readiness
Light on page 252for additional
information.To turn the right front passenger’s airbag on
again, insert your ignition key into the switch, push
in, and move the switch to the on position.
The right front passenger’s frontal airbag is now
enabled (may inate). SeeAirbag Off Light
on page 252for more information.
United StatesCanada
98

{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 252for 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 massagerscan affect how well the passenger sensing system
operates. You may want to consider not using
seat covers or other aftermarket equipment. See
Adding Equipment to Your Airbag-Equipped
Vehicle on page 105for 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.
103

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 666.
{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.
104

Your vehicle has one
double-sided key for the
ignition, all door
locks, and the spare tire
hoist lock, if your
vehicle has one.
If you ever lose your keys, your dealer will be able
to assist you with obtaining replacements.
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, call
the GM Roadside Assistance Center. See
Roadside Assistance Program on page 654.Remote Keyless Entry (RKE)
System
If the vehicle has a 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.
112

At times you may notice a decrease in 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 or
resynchronization is necessary. See “Battery
Replacement” and “Resynchronization”
underRemote Keyless Entry (RKE) System
Operation on page 113.
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.
113

If you set off the alarm by accident, turn off the
alarm by pressing unlock on the RKE transmitter or
by placing the key in the ignition and turning it
to START.
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 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.
If the alarm does not sound when it should, but
the vehicle’s headlamps ash, check to see if the
horn works. The horn fuse may be blown. To
replace the fuse, seeFuses and Circuit Breakers
on page 612.
If the alarm does not sound or the vehicle’s
headlamps do not ash, see your dealer for
service.
