46 Seats and Restraints
Questions and Answers About Seat Belts
Q: Will I be trapped in the vehicle after acrash if I am wearing a seat belt?
A: You could be— whether you are
wearing a seat belt or not. Your chance
of being conscious during and after a
crash, so you canunbuckle and get out,
is much greater if you are belted.
Q: If my vehicle has airbags, why should I have to wear seat belts?
A: Airbags are supplemental systems only.
They work withseat belts —not instead
of them. Whether or not an airbag is
provided, all occupants still have to
buckle up to get the most protection.
Also, in nearly all states and in all
Canadian provinces, the law requires
wearing seat belts.
Buckle To Drive
If equipped, this feature prevents the vehicle
from shifting out of P (Park) when the driver
seat belt is not buckled. The Buckle to Drive
feature must be turned ON in the
infotainment system to work. See Vehicle
Personalization 098 and if equipped, Teen
Driver 0160. If the engine is running, the
driver seat belt is not buckled, and the brake pedal is pressed with the vehicle in P (Park),
a message displays in the Driver Information
Center (DIC). Buckle the driver seat belt to
shift out of P (Park). Shifting from P (Park)
will be prevented once for each ignition
cycle.
For some fleet vehicles, the feature is
always ON and it cannot be turned OFF in
the infotainment system. Shifting from
P (Park) will be prevented each time the
above conditions exist.
On some models, Buckle to Drive may also
prevent shifting out of P (Park) if a front
passenger is unbuckled under similar
conditions. A message displays in the DIC.
Buckle the front passenger seat belt to shift
out of P (Park). This feature may not allow
the vehicle to shift out of P (Park) if an
object, such as a briefcase, handbag, grocery
bag, laptop, or other electronic device, is on
the front passenger seat. If this happens,
remove the object from the seat or buckle
the seat belt to shift out of P (Park).
If the driver, or on some vehicles, the
present front passenger remains unbuckled,
the DIC message will turn off after several
seconds and the vehicle can be shifted out
of P (Park). See
“Seat Belts”and“Child Restraints”
in the Index for information
about the importance of proper
restraint use.
If the driver seat belt, and in some vehicles
the front passenger seat belt, is unbuckled
when driving, the seat belt reminder chime
and light(s) will come on. See Seat Belt
Reminders 084. This feature may not
function properly if the airbag readiness
light is on. See Airbag Readiness Light 085.
How to Wear Seat Belts Properly
Follow these rules for everyone's protection.
There are additional things to know about
seat belts and children, including smaller
children and infants. If a child will be riding
in the vehicle, see Older Children061 or
Infants and Young Children 062. Review
and follow the rules for children in addition
to the following rules.
It is very important for all occupants to
buckle up. Statistics show that unbelted
people are hurt more often in crashes than
those who are wearing seat belts.
There are important things to know about
wearing a seat belt properly.

components of the airbag module may be
hot for several minutes. For location of the
airbags, seeWhere Are the Airbags? 054.
The parts of the airbag that come into
contact with you may be warm, but not too
hot to touch. There may be some smoke
and dust coming from the vents in the
deflated airbags. Airbag inflation does not
prevent the driver from seeing out of the
windshield or being able to steer the
vehicle, nor does it prevent people from
leaving the vehicle.
{Warning
When an airbag inflates, there may be
dust in the air. This dust could cause
breathing problems for people with a
history of asthma or other breathing
trouble. To avoid this, everyone in the
vehicle should get out as soon as it is
safe to do so. If you have breathing
problems but cannot get out of the
vehicle after an airbag inflates, then get
fresh air by opening a window or a door.
If you experience breathing problems
following an airbag deployment, you
should seek medical attention. The vehicle has a feature that may
automatically unlock the doors, turn on the
interior lamps and hazard warning flashers
after the airbags inflate. The feature may
also activate, without airbag inflation, after
an event that exceeds a predetermined
threshold.
After turning the ignition off and then on
again, the fuel system will return to normal
operation; the doors can be locked, the
interior lamps can be turned off, and the
hazard warning flashers can be turned off
using the controls for those features. If any
of these 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 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.
(Continued)
Warning (Continued)
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 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 0317 and
Event Data Recorders 0318.
.Let only qualified technicians work on the
airbag system. Improper service can mean
that the airbag system will not work
properly. See your dealer for service.

will light either ON or OFF, or the on or off
symbol, to let you know the status of the
front outboard passenger frontal airbag.
If the word ON or the on symbol is lit on
the passenger airbag status indicator, it
means that the front outboard passenger
frontal airbag is allowed to 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 front outboard passenger frontal airbag.
If, after several seconds, both status
indicator lights remain on, 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 the vehicle serviced right
away. SeeAirbag Readiness Light 085
for more information, including important
safety information.
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 0193.
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.
Caution
Modifications to the engine, transmission,
exhaust, intake, or fuel system, or the
use of replacement tires that do not
meet the original tire specifications, can
cause this light to come on. This could
lead to costly repairs not covered by the
vehicle warranty. This could also affect
the vehicle’s ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications0231.
If the light is flashing : A malfunction has
been detected that could damage the
emission control system and increase vehicle
emissions. Diagnosis and service may be
required.
To help prevent damage, reduce vehicle
speed and avoid hard accelerations and
uphill grades. If the light continues to flash, find a safe
place to park. Turn the vehicle off and wait
at least 10 seconds before restarting the
engine. If the light is still flashing, follow
the previous guidelines and see your dealer
for service as soon as possible.
If the light is on steady :
A malfunction has
been detected. Diagnosis and service may be
required.
Check the following:
.If fuel has been added to the vehicle
using the capless funnel adapter, make
sure that it has been removed. See
“Filling the Tank with a Portable Gas Can”
under Filling the Tank 0227. The
diagnostic system can detect if the
adapter has been left installed in the
vehicle, allowing fuel to evaporate into
the atmosphere. A few driving trips with
the adapter removed may turn off the
light.
.Poor fuel quality can cause inefficient
engine operation and poor driveability,
which may go away once the engine is
warmed up. If this occurs, change the fuel
brand. It may require at least one full
tank of the proper fuel to turn the light
off. See Recommended Fuel 0226.
If the light remains on, see your dealer.
Emissions Inspection and Maintenance
Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument panel to
the left of the steering wheel. Connecting
devices that are not used to perform an
Emissions Inspection/Maintenance test or to
service the vehicle may affect vehicle
operation. See Add-On Electrical Equipment
0 229. See your dealer if assistance is
needed.
The vehicle may not pass inspection if:
.The light is on when the engine is
running.
.The light does not come on when the
ignition is in Service Mode.
