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 1-31.
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.The lap part of the belt should be worn low and snug on
the hips, just touching the thighs. In a crash, this
applies force to the strong pelvic bones. And you would
be less likely to slide under the lap belt. If you slid
under it, the belt would apply force at your abdomen.
This could cause serious or even fatal injuries. The
shoulder belt should go over the shoulder and across
the chest. These parts of the body are best able to take
belt restraining forces.

The safety belt locks if there is a sudden stop or a
crash. The safety belt also locks if you pull the belt very
quickly out of the retractor.
{CAUTION:
You can be seriously hurt if your shoulder belt
is too loose. In a crash, you would move
forward too much, which could increase injury.
The shoulder belt should t against your body.
To unlatch the belt, push the button on the buckle.
Rear Safety Belt Comfort Guides
Rear shoulder belt comfort guides may provide added
safety belt comfort for older children who have outgrown
booster seats and for some adults. When installed on
a shoulder belt, the comfort guide positions the belt
away from the neck and head.
Comfort guides are provided for each passenger in the
second row seat and one guide for the single third
row seat. Here is how to install a comfort guide and use
the safety belt:
1. Remove the guide from its storage clip on the trim
panel near the side of the seatback or from the side
of the seat.

3. Tighten the top tether.
{CAUTION:
If the seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
push and pull on the seatback to be sure it is
locked.
4. Return the rear passenger side seatback to its
upright position. Ensure that the seatback locks
and the safety belt is routed properly. Then lower
the seat cushion until the seatback and the
seat cushion lock into position.
5. Push and pull the child restraint in different
directions to be sure it is secure.
Second and Third Row Positions — SUV
1. Attach and tighten the lower attachments to
the lower anchors. If the child restraint does
not have lower attachments or the desired seating

belts. Refer to your child restraint manufacturer
instructions and the instructions in this manual.
1.1. Find the lower anchors for the desired
seating position.

Airbag ination does not prevent the driver from seeing
out of the windshield or being able to steer the vehicle,
nor does it stop people from leaving the vehicle.
{CAUTION:
When an airbag inates, there is 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 and turn the interior lamps on when
the airbags inate (if battery power is available). You can
lock the doors again and turn the interior lamps off by
using the door lock and interior lamp controls.In many crashes severe enough to inate the 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 they
inate, you will need some new parts for your
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.
Your vehicle is equipped with a crash sensing and
diagnostic module which records information after
a crash. SeeVehicle Data Collection and Event
Data Recorders on page 7-10.
Let only qualied technicians work on your airbag
system. Improper service can mean that an
airbag system will not work properly. See your
dealer for service.

At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-5.
If you are still having trouble, see your dealer or a
qualied technician for service.
Remote Keyless Entry System
Operation
You can lock and unlock your doors from about 3 feet
(1 m) up to 100 feet (30 m) away using the remote
keyless entry transmitter supplied with your vehicle.
K(Unlock):Press this
button once to unlock the
driver’s door. The
interior lamps will come
on. Pressing unlock again
within three seconds
will cause the remaining
doors to unlock.
You can choose different feedback options for each
press of the unlock button. See “Lock Feedback” and
“Unlock Feedback” underDIC Vehicle Customization on
page 3-55for more information.
2-5

Q(Lock):Press this button once to lock all of the
doors. Pressing lock again within three seconds
may cause the horn to chirp for lock conrmation. You
can choose different feedback options for each press
of the lock button. See “Lock Feedback” and “Unlock
Feedback” underDIC Vehicle Customization on
page 3-55for more information.
L(Panic):Press this button to sound the horn and
ash the headlamps and taillamps for up to 30 seconds.
Panic can be turned off by pressing the button again,
by waiting for 30 seconds, or by starting the vehicle.
Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to prevent
another transmitter from unlocking your vehicle. If a
transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded
the new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of
four transmitters matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter will not
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it is probably time to change the battery.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.
