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:
Seats and Restraint Systems in Section 1
Features and Controls in Section 2
Instrument Panel Overview in Section 3
Climate Controls in Section 3

Heated Seats
Your vehicle may have
heated front seats.
The buttons used to
control this feature
are located on the front
door armrests. The
engine must be running
for the heated seat
feature to work.
To heat the entire seat, press the horizontal button
with the heated seat and seatback symbol. Press
the button to cycle through the temperature settings
of high, medium, and low and to turn the heated
seat off. The indicator lights above the button will
come on to designate the level of heat selected:
three for high, two for medium, and one for low.The low setting warms the seatback and seat
cushion until the seat temperature is near body
temperature. The medium and high settings heat
the seatback and seat cushion to a slightly higher
temperature. You will be able to feel heat in about
two minutes.
To heat only the seatback, press the vertical
button with the heated seatback symbol. An
indicator light on the button will come on to
designate that only the seatback is being heated.
Additional presses will cycle through the heat
levels for the seatback only.
The feature will shut off automatically when the
ignition is turned off.

{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 200
andPassenger Safety Belt Reminder Light
on page 200.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.
A few crashes are mild, and some crashes can
be so serious that even buckled up, a person
would not survive. But most crashes are in
between. In many of them, people who buckle up
can survive and sometimes walk away. Without
belts they could have been badly hurt or killed.
After more than 40 years of safety belts in
vehicles, the facts are clear. In most crashes
buckling up does matter... a lot!
21

The lap-shoulder belt may lock if you pull the
belt across you very quickly. If this happens,
let the belt go back slightly to unlock it.
Then pull the belt across you more slowly.
4. Push the latch plate into the buckle until
it clicks.
Pull up on the latch plate to make sure it
is secure.
If the belt is not long enough, seeSafety Belt
Extender on page 41.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle
the safety belt quickly if you ever had to.
5. To make the lap part tight, pull up on the
shoulder belt.
It may be necessary to pull stitching on the
safety belt through the latch plate to fully
tighten the lap belt on smaller occupants.
27

Lap-Shoulder Belt
All rear seat positions have lap-shoulder belts.
Here is how to wear one properly.
1. Pick up the latch plate and pull the belt across
you. Do not let it get twisted.
The shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let
the belt go back slightly to unlock it. Then
pull the belt across you more slowly.
2. Push the latch plate into the buckle until
it clicks.Pull up on the latch plate to make sure it
is secure.
When the shoulder belt is pulled out all the
way, it will lock. If it does, let it go back all the
way and start again.
If the belt is not long enough, seeSafety Belt
Extender on page 41.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle
the safety belt quickly if you ever had to.
3. To make the lap part tight, pull up on the
shoulder part.
36

If your child restraint has the LATCH system, see
Lower Anchors and Tethers for Children (LATCH)
on page 56.
There is no top tether anchor at the right front
seating position. Do not secure a child seat in this
position if a national or local law requires that
the top tether be anchored or if the instructions
that come with the child restraint say that the top
tether must be anchored. SeeLower Anchors
and Tethers for Children (LATCH) on page 56
if the 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 82. 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. See
Manual Seats on page 8orPower 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.
SeePassenger Airbag Status Indicator
on page 202.
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.
68

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.Airbag System
Your vehicle has a frontal airbag for the driver
and a frontal airbag for the right front passenger.
Your vehicle may also have roof-mounted side
impact airbags designed for either side impact or
rollover deployment. Roof-mounted side impact
airbags are available for the driver and the
passenger seated directly behind the driver and
for the right front passenger and the passenger
seated directly behind that passenger.
If your vehicle has roof-mounted side impact
airbags, the word AIRBAG will appear on
the airbag covering on the sidewall trim near
the driver’s and right front passenger’s window.
71

{CAUTION:
Anyone who is up against, or very close
to, any airbag when it inates can be
seriously injured or killed. Airbags plus
lap-shoulder belts offer the best
protection for adults, but not for young
children and infants. Neither the vehicle’s
safety belt system nor its airbag system is
designed for them. Young children and
infants need the protection that a child
restraint system can provide. Always
secure children properly in your vehicle.
To read how, seeOlder Children on
page 42orInfants and Young Children
on page 45.There is an airbag
readiness light on the
instrument panel cluster,
which shows the
airbag symbol.
The system checks the airbag electrical system
for malfunctions. The light tells you if there is
an electrical problem. SeeAirbag Readiness Light
on page 201for more information.
74

The passenger sensing system is designed to turn
off the right front passenger’s frontal airbag if:
The right front passenger seat is unoccupied.
The system determines that an infant is
present in a rear-facing infant seat.
The system determines that a small child is
present in a forward-facing child restraint.
The system determines that a small child is
present in a booster seat.
A right front passenger takes his/her weight off
of the seat for a period of time.
The right front passenger seat is occupied by
a smaller person, such as a child who has
outgrown child restraints.
Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned
off the passenger’s frontal airbag, the off indicator
in the rearview mirror will light and stay lit to
remind you that the airbag is off.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 following the child restraint
manufacturer’s directions and refer toSecuring a
Child Restraint in the Right Front Seat Position
on page 66.
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.
