windshield breakage may also
occur from the front outboard
passenger airbag.
.Airbags are designed to
inflate only once. After an
airbag inflates, 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 the vehicle
covers the need to replace
other parts.
.The vehicle has a crash
sensing and diagnostic
module which records
information after a crash.
See Vehicle Data Recording
and Privacy0479 and
Event Data Recorders 0480.
.Let only qualified 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
The vehicle has a passenger
sensing system for the front
outboard passenger position.
The passenger airbag status
indicator will light on the
overhead console when the
vehicle is started.
The words ON and OFF, and
the symbols for on and off, will
be visible during the system
check. When the system check
is complete, either the word
ON or OFF, and the symbol for
on or off, will be visible. See
Passenger Airbag Status
Indicator 0133. The passenger sensing
system turns off the front
outboard passenger frontal
airbag under certain
conditions. No other airbag is
affected by the passenger
sensing system.
The passenger sensing
system works with sensors
that are part of the front
outboard passenger seat and
seat belt. The sensors are
designed to detect the
presence of a properly seated
occupant and determine if the
front outboard passenger
frontal airbag should be
allowed to inflate or not.
According to accident
statistics, children are safer
when properly secured in a
rear seat in the correct child
restraint for their weight
and size.
Whenever possible, children
aged 12 and under should be
secured in a rear seating
position.

104 Seats and Restraints
If the retractor is not
locked, repeat
Steps 4 and 5.
6. If the child restraint has a top tether, follow the child
restraint manufacturer's
instructions regarding the
use of the top tether. See
Lower Anchors and
Tethers for Children
(LATCH System) 092.
7. Before placing a child in the child restraint, make
sure it is securely held in
place. To check, grasp the
child restraint at the seat
belt path and attempt to
move it side to side and
back and forth. When the
child restraint is properly
installed, there should be
no more than 2.5 cm (1 in)
of movement.
To remove the child restraint,
unbuckle the vehicle seat belt
and let it return to the stowed
position. If the top tether is
attached to a top tether
anchor, disconnect it.Securing Child
Restraints (With the
Seat Belt in the
Front Seat)
This vehicle has airbags.
A rear seat is a safer place to
secure a forward-facing child
restraint. See Where to Put
the Restraint 091.
In addition, the vehicle has a
passenger sensing system
which is designed to turn off
the front outboard passenger
frontal airbag under certain
conditions. See Passenger
Sensing System 078 and
Passenger Airbag Status
Indicator 0133 for more
information, including
important safety information.
Never put a rear-facing child
seat in the front. This is
because the risk to the
rear-facing child is so great,
if the airbag deploys.
{Warning
A child in a rear-facing child
restraint can be seriously
injured or killed if the front
outboard passenger frontal
airbag inflates. This is
because the back of the
rear-facing child restraint
would be very close to the
inflating airbag. A child in a
forward-facing child
restraint can be seriously
injured or killed if the front
outboard passenger frontal
airbag inflates and the
passenger seat is in a
forward position.
Even if the passenger
sensing system has turned
off the front outboard
passenger frontal airbag, no
system is fail-safe. No one
can guarantee that an
airbag will not deploy under
some unusual circumstance,
even though it is turned off.

Charging System
Light
The charging system light
comes on briefly when the
ignition is turned on, but the
engine is not running, as a
check to show the light is
working. It should go out when
the engine is started.
If the light stays on, or comes
on while driving, there may be
a problem with the electrical charging system. Have it
checked by your dealer.
Driving while this light is on
could drain the battery.
When this light comes on, or is
flashing, the Driver Information
Center (DIC) also displays a
message.
If a short distance must be
driven with the light on, be
sure to turn off all
accessories, such as the radio
and air conditioner. Find a safe
place to stop the vehicle.
Malfunction Indicator
Lamp (Check Engine
Light)
This light is part of the
vehicle’s emission control
on-board diagnostic system.
If this light is on while the
engine is running, a
malfunction has been
detected and the vehicle may
require service. The light
should come on to show that it
is working when the ignition is
in Service Mode. See Ignition
Positions
0257.
Malfunctions are often
indicated by the system
before any problem is
noticeable. Being aware of the
light and seeking service
promptly when it comes on
may prevent damage.
Caution
If the vehicle is driven
continually with this light on,
the emission control system
may not work as well, the
fuel economy may be lower,
and the vehicle may not run
smoothly. This could lead to
costly repairs that might not
be covered by the vehicle
warranty.
