any time, press one of the power seat controls,
memory buttons, power mirror buttons, or

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 582.
Let only qualied technicians work on your
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 230.
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.

{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 229for
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 107for 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.
105

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 589.
{CAUTION:
For up to 10 seconds after the ignition
key 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.

or liftgate to delay until the wipers are parked off
the liftglass.
Both the liftglass and liftgate have an electric
latch. If the battery is disconnected or has
low voltage, the liftglass and liftgate will not open.
The liftglass and liftgate will resume operation
when the battery is reconnected and charged.
