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

away. See Airbag Readiness
Light0124 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:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such
as blankets, cushions, seat
covers, seat heaters,
or seat massagers. 4. Reinstall the child restraint
following the directions
provided by the child
restraint manufacturer and
refer to Securing Child
Restraints (With the Seat
Belt in the Rear Seat) 095
or Securing Child
Restraints (With the Seat
Belt in the Front Seat)
0 98.
Make sure the seat belt
retractor is locked by
pulling the shoulder belt all
the way out of the
retractor when installing
the child restraint, even if
the child restraint is
equipped with a seat belt
lock off. When the
retractor lock is set, the
belt can be tightened but
not pulled out of the
retractor.
5. If, after reinstalling the child restraint and
restarting the vehicle, the
ON indicator is still lit, turn
the vehicle off. Then
slightly recline the vehicle

(Continued)
Warning (Continued)
resulting in serious injury or
even death. To help make
sure the airbag systems are
working properly after a
crash, have them inspected
and any necessary
replacements made as soon
as possible.
If an airbag inflates, you will
need to replace airbag system
parts. See your dealer for
service.
If the airbag readiness light
stays on after the vehicle is
started or comes on when you

Warning Lights,
Gauges, and

Warning lights and gauges can
signal that something is wrong
before it becomes serious
enough to cause an expensive
repair or replacement. Paying
attention to the warning lights
and gauges could prevent
injury.

Some warning lights come on
briefly when the engine is
started to indicate they are
working. When one of the
warning lights comes on and
stays on while driving, or when
one of the gauges shows
there may be a problem, check

to do. Waiting to do repairs
can be costly and even

Airbag Readiness
Light
This light shows if there is an
electrical problem with the
airbag system. It is located in
the instrument cluster. The
system check includes the
airbag sensor(s), the
passenger sensing system,
the pretensioners, the airbag
modules, the wiring, and the
crash sensing and diagnostic
module. For more information
on the airbag system, see
Airbag System
065.
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.

Passenger Airbag
Status Indicator
The vehicle has a passenger
sensing system. See
Passenger Sensing System
0 72 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, are 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, are 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, there may be a problem
with the lights or the
passenger sensing system.
See your dealer for service.
