66 Seats and Restraints
systems are damaged in the
crash they may not operate as
normal.
{Warning
A crash severe enough to
inflate the airbags may have
also damaged important
functions in the vehicle, such
as the brake and steering
systems, etc. Even if the
vehicle appears to be
drivable after a moderate
crash, there may be
concealed damage that
could make it difficult to
safely operate the vehicle.
Use caution if attempting to
restart the vehicle after a
crash has occurred.
Plug-in vehicles have a high
voltage battery and a
standard 12-volt battery.
If an airbag inflates or the
vehicle has been in a crash,
the sensing system may shut
down the high voltage system. When this occurs, the high
voltage battery is
disconnected and the vehicle
will not start. Before the
vehicle can be operated again,
it must be serviced at your
dealer.
In many crashes severe
enough to inflate the airbag,
windshields are broken by
vehicle deformation. Additional
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 Privacy
0397 and
Event Data Recorders 0398.
.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.

68 Seats and Restraints
Warning (Continued)
always move the seat as far
back as it will go. It is better
to secure child restraints in
the rear seat. Consider
using another vehicle to
transport the child when a
rear seat is not available.
The passenger sensing
system is designed to turn off
the front outboard passenger
frontal airbag and knee
airbag if:
.The front outboard
passenger seat is
unoccupied.
.The system determines an
infant is present in a child
restraint.
.A front outboard passenger
takes his/her weight off of
the seat for a period of time.
When the passenger sensing
system has turned off the
front outboard passenger
frontal airbag and knee airbag,
the OFF indicator will light and stay lit as a reminder that the
airbags are off. See Passenger
Airbag Status Indicator
0113.
The passenger sensing
system is designed to turn on
the front outboard passenger
frontal airbag and knee airbag,
anytime the system senses
that a person of adult size is
sitting properly in the front
outboard passenger seat.
When the passenger sensing
system has allowed the
airbags to be enabled, the ON
indicator will light and stay lit
as a reminder that the airbags
are active.
For some children, including
children in child restraints, and
for very small adults, the
passenger sensing system
may or may not turn off the
front outboard passenger
frontal airbag and knee airbag,
depending upon the person's
seating posture and body
build. Everyone in the vehicle
who has outgrown child
restraints should wear a seat belt properly
—whether or not
there is an airbag for that
person.
{Warning
If the airbag readiness light
ever comes on and stays on,
it means that something may
be wrong with the airbag
system. To help avoid injury
to yourself or others, have
the vehicle serviced right
away. See Airbag Readiness
Light 0112 for more
information, including
important safety
information.
If the On Indicator Is Lit
for a Child Restraint
The passenger sensing
system is designed to turn off
the front outboard passenger
frontal airbag and knee airbag,
if the system determines that
an infant is present in a child
restraint. If a child restraint
has been installed and the ON
indicator is lit:

modules, the wiring, and the
crash sensing and diagnostic
module. For more information
on the airbag system, see
Airbag System059.
The airbag readiness light
comes on for several seconds
when the vehicle is started.
If the light does not come on
then, have it fixed immediately.
{Warning
If the airbag readiness light
stays on after the vehicle is
started or comes on while
driving, it means the airbag
system might not be working
properly. The airbags in the
vehicle might not inflate in a
crash, or they could even

Warning (Continued)
inflate without a crash. To
help avoid injury, have the
vehicle serviced right away.
If there is a problem with the
airbag system, a Driver
Information Center (DIC)
message may also come on.
Passenger Airbag
Status Indicator
The vehicle has a passenger
sensing system. See
Passenger Sensing System
0 66 for important safety
information. The overhead
console has a passenger
airbag status indicator.
When the vehicle is started,
the passenger airbag status
indicator will light ON and OFF,
and the symbols for on and
off, for several seconds as a
system check. Then, after
several more seconds, the
status indicator will light either
ON or OFF, and either the
symbol for on or off, to let you
know the status of the front
outboard passenger frontal
airbag and knee airbag.
If the word ON, and the on
symbol, is lit on the passenger
airbag status indicator, it
means that the front outboard
passenger frontal airbag and
knee airbag are allowed to
inflate.
If the word OFF, and the off
symbol, is lit on the passenger
airbag status indicator, it
means that the passenger
sensing system has turned off
the front outboard passenger
frontal airbag and knee airbag.

If, after several seconds, both
status indicator lights remain
on, or if there are no lights at
all, or if the airbag readiness
light is on, there may be a
problem with the lights or the
passenger sensing system.
See your dealer for service
right away.
{Warning
If the airbag readiness light
ever comes on and stays on,
it means that something may
be wrong with the airbag
system. To help avoid injury
to yourself or others, have

Charging System
Light (12-Volt Battery)
The charging system light
comes on briefly when the
vehicle is started, as a check
to show the light is working.
If the light stays on, or comes
on while driving, there could
be a problem with the
electrical charging system.
Have it checked by your
dealer. Driving while this light
is on could drain the 12-volt
battery.
If a short distance must be
driven with the light on, be
sure to turn off all
accessories, such as the radio.
Find a safe place to stop the
vehicle.
Low State of Charge
Light
This light comes on when the
vehicle state of charge is low.
Proceed to a charging station
to charge the vehicle.
Charge Cord
