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:

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

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.

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.

Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is how to
wear it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight.
To see how, see “Seats” in the Index.
3. Pick up the latch plate and pull the belt across
you. Do not let it get twisted.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 38.
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. Move the shoulder belt height adjuster to the
height that is right for you. Improper shoulder
belt height adjustment could reduce the
effectiveness of the safety belt in a crash. See
Shoulder Belt Height Adjustment on page 29.

Rear Seat Passengers
It is very important for rear seat passengers to
buckle up! Accident statistics show that unbelted
people in the rear seat are hurt more often in
crashes than those who are wearing safety belts.
Rear passengers who are not safety belted
can be thrown out of the vehicle in a crash. And
they can strike others in the vehicle who are
wearing safety belts.
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.

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.
