Safety Warnings and Symbols
Warning messages found on vehicle labels and in this
manual describe hazards and what to do to avoid or
reduce them.
Dangerindicates a hazard with a high level of risk
which will result in serious injury or death.
Warning orCaution indicates a hazard that could result
in injury or death.
{WARNING:
These mean there is something that could hurt
you or other people.
Notice: This means there is something that could
result in property or vehicle damage. This would not
be covered by the vehicle's warranty.
A circle with a slash
through it is a safety
symbol which means “Do
Not,” “Do not do this,” or
“Do not let this happen.”

{WARNING:
A crash severe enough to inflate the airbags may
have also damaged important functions in the
vehicle, such as the fuel system, 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 you should attempt to restart the
engine after a crash has occurred.
In many crashes severe enough to inflate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from
the right front 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 your 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
on
page 8‑18and Event Data Recorderson
page 8‑18.
.Let only qualified technicians work on the airbag
systems. Improper service can mean that an
airbag system will not work properly. See your
dealer/retailer for service.
Passenger Sensing System
If the vehicle has the passenger airbag status indicator
pictured in the following illustration, then the vehicle has
a passenger sensing system for the right front
passenger position. The passenger airbag status
indicator, if equipped, is visible on the overhead console
when the vehicle is started.
In addition, if the vehicle has a passenger sensing
system for the right front passenger position, the label
on the vehicle's sun visors refers to “ADVANCED
AIRBAGS”.
2-85

For some children, including children in child restraints,
and for very small adults, the passenger sensing
system may or may not turn off the right front passenger
frontal airbag, depending upon the person's seating
posture and body build. Everyone in your vehicle who
has outgrown child restraints should wear a safety 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
on page 4‑28
for more information, including important safety
information.
If the On Indicator is Lit for 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 a Child Restraint in the Right
Front Seat Position on page 2‑71.
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
seatback and adjust the seat cushion, if adjustable,
to make sure that the vehicle seatback is not
pushing the child restraint into the seat cushion.
Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head restraint. See Head Restraints
on
page 2‑2.
6. Restart the vehicle. The passenger sensing system may or may not
turn off the airbag for a child in a child restraint
depending upon the child’s seating posture and
body build. It is better to secure the child restraint
in a rear seat.

occur after washing the vehicle in cold weather.
The message may not clear until the frost or ice
has melted.
.A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the liftgate during the
last drive cycle. Once the attached object is
removed, URPA will return to normal operation.
.A tow bar is attached to the vehicle.
.The vehicle's bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
.Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.

WARNING: (Continued)
properly. The airbags in the vehicle might not
inflate in a crash, or they could even inflate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also
come on. See DIC Warnings and Messages
on
page 4‑56for more information.
Passenger Airbag Status Indicator
If the vehicle has the airbag status indicator pictured in
the following illustration, then the vehicle has a
passenger sensing system for the right front passenger
position. The passenger airbag status indicator is on the
overhead console. See Passenger Sensing System
on
page 2‑85for important safety information. In addition, if the vehicle has a passenger sensing
system for the right front passenger position, the label
on the vehicle's sun visors refers to
“ADVANCED
AIRBAGS”.
United StatesCanada
When the vehicle is started, the passenger airbag
status indicator will light ON and OFF, or the symbols
for on and off, for several seconds as a system check.
If you are using remote start, if equipped, to start the
vehicle from a distance, you may not see the system
check.
Then, after several more seconds, the status indicator
will light either ON or OFF, or either the on or off symbol
to let you know the status of the right front passenger
frontal airbag.
4-29

If the word ON or the on symbol is lit on the passenger
airbag status indicator, it means that the right front
passenger frontal airbag is enabled (may inflate).
If the word OFF or the off symbol is lit on the airbag
status indicator, it means that the passenger sensing
system has turned off the right front passenger frontal
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/retailer for service.
{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. SeeAirbag Readiness Light
on page 4‑28
for more information, including important safety
information.
Charging System Light
This light comes on briefly
when the ignition key is
turned to START, but the
engine is not running,
as a check to show it is
working.
If it does not, have the vehicle serviced by your
dealer/retailer.
The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a problem
with the charging system. A charging system message
in the Driver Information Center (DIC) can also appear.
See DIC Warnings and Messages
on page 4‑56for
more information. This light could indicate that there
are problems with a generator drive belt, or that there
is an electrical problem. Have it checked right away.
If the vehicle must be driven a short distance with the
light on, turn off accessories, such as the radio and
air conditioner.
