Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something
that could damage your vehicle.
A notice tells about something that can damage
the vehicle. Many times, this damage would not be
covered by your vehicle’s warranty, and it could
be costly. But the notice will tell what to do to help
avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle.
They use the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along
with the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the
following topics:

Power Lumbar
Your driver’s seat may have power lumbar. The
control is located on the outboard side of the seat
cushion.
Press the front of the control to increase lumbar
support. Press the rear of the control to decrease
lumbar support.
Keep in mind that as your seating position
changes, as it may during long trips, so should the
position of your lumbar support. Adjust the seat
as needed.
Heated Seats
If your vehicle has this
feature, the buttons are
located on the climate
control panel.
Press the button once to activate the high heat
setting. Both indicator lights on the button will come
on. Press the button again to select the lower
temperature setting. Only one indicator light will
come on. Press the button a third time to turn the
heat off.
This feature only works when the ignition is on.

Safety Belts
Safety Belts: They Are for Everyone
This part of the manual tells you how to use
safety belts properly. It also tells you some things
you should not do with safety belts.
{CAUTION:
Do not let anyone ride where he or she
cannot wear a safety belt properly. If you
are in a crash and you are not wearing a
safety belt, your injuries can be much
worse. You can hit things inside the
vehicle or be ejected from it. You can be
seriously injured or killed. In the same
crash, you might not be, if you are
buckled up. Always fasten your safety
belt, and check that your passengers’
belts are fastened properly too.
{CAUTION:
It is extremely dangerous to ride in a
cargo area, inside or outside of a vehicle.
In a collision, people riding in these areas
are more likely to be seriously injured or
killed. Do not allow people to ride in any
area of your vehicle that is not equipped
with seats and safety belts. Be sure
everyone in your vehicle is in a seat and
using a safety belt properly.
Your vehicle has indicators to remind you and your
passengers to buckle your safety belts. SeeSafety
Belt Reminder Light on page 181andPassenger
Safety Belt Reminder Light on page 182.
In most states and in all Canadian provinces,
the law says to wear safety belts. Here is
why:They work.
You never know if you will be in a crash. If you do
have a crash, you do not know if it will be a
bad one.

Securing a Child Restraint in the
Center Front Seat Position
{CAUTION:
A child in a child restraint in the center
front seat can be badly injured or killed by
the right front passenger’s airbag if it
inates. Never secure a child restraint in
the center front seat. It is always better to
secure a child restraint in the rear seat.
Do not secure a child restraint in the center front
seat position.
Securing a Child Restraint in the
Right Front Seat Position
Your vehicle has a right front passenger’s airbag. A
rear seat is a safer place to secure a forward-facing
child restraint. SeeWhere to Put the Restraint on
page 50.
In addition, your vehicle has a passenger sensing
system. The passenger sensing system is designed
to turn off the right front passenger’s frontal airbag
when an infant in a rear-facing infant seat or a small
child in a forward-facing child restraint or booster
seat is detected. SeePassenger Sensing System
on page 75andPassenger Airbag Status Indicator
on page 183for more information on this including
important safety information.
61

SeeLower Anchors and Tethers for Children
(LATCH) on page 51if your child restraint has
a top tether.
You will be using the lap-shoulder belt to secure
the child restraint in this position. Be sure to follow
the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Your vehicle has a right front passenger’s
frontal airbag. SeePassenger Sensing System
on page 75. We recommend that rear-facing
child restraints be secured in a rear seat, even
if the airbag is off. If your child restraint is
forward-facing, move the seat as far back as it
will go before securing the child restraint in this
seat. SeePower Seats on page 9.
When the passenger sensing system has
turned off the right front passenger’s frontal
airbag, the off indicator in the passenger airbag
status indicator should light and stay lit when
you turn the ignition to RUN or START. See
Passenger Airbag Status Indicator on page 183.2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and
shoulder portions of the vehicle’s safety belt
through or around the restraint. The child
restraint instructions will show you how.
4. Buckle the belt. Make sure the release button
is positioned so you would be able to unbuckle
the safety belt quickly if you ever had to.
63

7. Push and pull the child restraint in different
directions to be sure it is secure.
8. If the airbag is off, the off indicator on the
instrument panel will be lit and stay lit
when the key is turned to RUN or START.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child
restraint.
If, after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the
child restraint into the seat cushion. If this happens,
slightly recline the vehicle’s seatback and adjust the
seat cushion if possible. Also make sure the child
restraint is not trapped under the vehicle head
restraint. If this happens, adjust the head restraint.If the on indicator is still lit, secure the child in the
child restraint in a rear seat position in the vehicle
and check with your dealer.
To remove the child restraint, just unbuckle the
vehicle’s safety belt and let it go back all the way.
The safety belt will move freely again and be
ready to work for an adult or larger child
passenger.

When Should an Airbag Inate?
The driver’s and right front passenger’s frontal
airbags are designed to inate in moderate to
severe frontal or near-frontal crashes. But they are
designed to inate only if the impact exceeds a
predetermined deployment threshold. Deployment
thresholds take into account a variety of desired
deployment and non-deployment events and are
used to predict how severe a crash is likely to be in
time for the airbags to inate and help restrain the
occupants. Whether your frontal airbags will or
should deploy is not based on how fast your vehicle
is traveling. It depends largely on what you hit, the
direction of the impact and how quickly your vehicle
slows down.In addition, your vehicle has “dual-stage” frontal
airbags, which adjust the restraint according to
crash severity. Your vehicle has electronic frontal
sensors which help the sensing system distinguish
between a moderate frontal impact and a more
severe frontal impact. For moderate frontal impacts,
these airbags inate at a level less than full
deployment. For more severe frontal impacts, full
deployment occurs. If the front of your vehicle goes
straight into a wall that does not move or deform,
the threshold level for the reduced deployment is
about 12 to 16 mph (19 to 26 km/h), and the
threshold level for a full deployment is about
18 to 22 mph (29 to 35.5 km/h). The threshold level
can vary, however, with specic vehicle design, so
that it can be somewhat above or below this range.
71

What Will You See After an Airbag
Inates?
After a frontal airbag inates, it quickly deates, so
quickly that some people may not even realize the
airbag inated. Roof-mounted side impact airbags
may still be at least partially inated minutes after
the vehicle comes to rest. Some components of the
airbag module — the steering wheel hub for the
driver’s airbag, the instrument panel for the right
front passenger’s airbag, or the ceiling of your
vehicle near the side windows for vehicles with
roof–mounted side impact airbags — may be hot for
a short time. 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 deated airbags. Airbag
ination 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.
{CAUTION:
When an airbag inates, 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 inates, 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.
Your vehicle has a feature that may automatically
unlock the doors, turn the interior lamps on, and
turn on the hazard warning ashers when the
airbags inate. You can lock the doors again, turn
the interior lamps off, and turn the hazard warning
ashers off by using the controls for those features.
74

In many crashes severe enough to inate an airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur
from the right front passenger airbag.
Airbags are designed to inate only once. After
airbags inate, 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 other parts that need to be replaced.
Your vehicle has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Collection and
Event Data Recorders on page 489.
Let only qualied technicians work on the
airbag system. Improper service can mean that
your airbag system will not work properly. See
your dealer for service.
Passenger Sensing System
Your vehicle has a passenger sensing system. The
passenger airbag status indicator on the instrument
panel will be visible when you turn your ignition key
to RUN or START.
The passenger airbag
status indicator will
light ON and OFF for
several seconds as a
system check.
If you use remote start to start your vehicle from a
distance, if your vehicle has this feature, you may
not see the system check. When the system check
is complete, either the word ON or the word OFF
will be visible. SeePassenger Airbag Status
Indicator on page 183.
The passenger sensing system will turn off the
right front passenger’s frontal airbag under certain
conditions. The driver’s airbags are not part of
the passenger sensing system.
