•Check belt fit periodically. A child’s squirming or
slouching can move the belt out of position.
•If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
the back.
Lower Anchors and Tether for CHildren (LATCH)
Your vehicle’s rear seat is equipped with the child
restraint anchorage system called LATCH. The LATCH
system provides for the installation of the child restraint
without using the vehicle’s seat belts, instead securing
the child restraint using lower anchorages and upper
tether straps from the child restraint to the vehicle
structure.
LATCH-compatible child restraint systems are now avail-
able. However, because the lower anchorages are to beintroduced over a period of years, child restraint systems
having attachments for those anchorages will continue to
also have features for installation using the vehicle’s seat
belts. Child restraints having tether straps and hooks for
connection to the top tether anchorages have been avail-
able for some time. For some older child restraints, many
child restraint manufacturers offer add-on tether strap
kits or retro-fit kits. You are urged to take advantage of all
the available attachments provided with your child re-
straint in any vehicle.
NOTE:When using the LATCH attaching system to
install a child restraint, please ensure that all seat belts
not being used for occupant restraints are stowed and out
of reach of children. Remind all children in the vehicle
that the seat belts are not toys and should not be played
with, and never leave your child unattended in the
vehicle.

gap panel. They are not visible until you fold the gap
panel down. Do not use the cargo tie down hooks
located on the floor behind the seat.Finally, tighten all
three straps as you push the child restraint rearward and
downward into the seat, removing slack in the straps
according to the child restraint manufacturer’s instruc-
tions.
WARNING!
Improper installation of a child restraint to the
LATCH anchorages can lead to failure of an infant or
child restraint. The child could be badly injured or
killed. Follow the manufacturer’s directions exactly
when installing an infant or child restraint.
Installing Child Restraints Using The Vehicle Seat
Belts
The seat belts in the passenger seating positions are
equipped with an Automatic Locking Retractor (ALR) tosecure a Child Restraint System (CRS). These types of
seat belts are designed to keep the lap portion of the seat
belt tight around the child restraint so that it is not
necessary to use a locking clip. The ALR will make a
ratcheting noise if you extract the entire belt from the
retractor and then allow the belt to retract into the
retractor. For additional information on ALR, refer to
“Automatic Locking Mode” description under “Seat
Belts in Passenger Seating Positions” section. The chart
below defines the seating positions with an Automatic
Locking Retractor (ALR).

90 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Installing a Child Restraint with an ALR:
1. To install a child restraint with ALR, first, pull enough
of the seat belt webbing from the retractor to route it
through the belt path of the child restraint. Slide the latch
plate into the buckle until you hear a “click.” Next,
extract all the seat belt webbing out of the retractor and
then allow the belt to retract into the retractor. As the belt
retracts, you will hear a ratcheting sound. This indicates
the safety belt is now in the Automatic Locking mode.
2. Finally, pull on any excess webbing to tighten the lap
portion around the child restraint. Any seat belt system
will loosen with time, so check the belt occasionally, and
pull it tight if necessary.
To attach a child restraint tether strap:
For rearward facing infant seats secured in the center seat
position with the vehicle seat belts, the rear center seat
position has an armrest tether that secures the arm rest inthe upward position. To access the center seat arm rest
tether first lower the arm rest. The tether is located
behind the armrest and hooked onto the plastic seat
backing.

WARNING!
•An incorrectly anchored tether strap could lead to
increased head motion and possible injury to the
child. Use only the anchor positions directly be-
hind the child seat to secure a child restraint top
tether strap.
•Do not use the cargo tie downs located on the load
floor. Improper usage of the tether can lead to a
failure of an infant or child restraint. The child
could be badly injured or killed.
Top Tether Strap Attachment
For the center seating position route the tether strap over
the seatback and headrest then attach the hook to thetop
tether anchoragelocated on the back of the seatbehind
the gap panel.For the outboard seating positions, route
the tether strap under the headrests and attach the hook
to thetop tether anchoragelocated on the back of the seatbehind the gap panel. Please note the top tether anchor-
ages are not visible until you fold the gap panel down.
Do not use the cargo tie down hooks located on the
floor behind the seats.
Transporting Pets
Air Bags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
an accident. Pets should be restrained in the rear seat in
pet harnesses or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the drivetrain
(engine, transmission, clutch, and rear axle) in your new
vehicle.
Drive moderately during the first 500 mi (800 km). After
the initial 60 mi (100 km), speeds up to 50 or 55 mph (80
or 90 km/h) are desirable.
94 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (i.e., bent retractor,
torn webbing, etc.). If there is any question regarding belt
or retractor condition, replace the belt.
Air Bag Warning Light
The light should come on and remain on for four to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by an autho-
rized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is
inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit the footwell of your
vehicle. Use only floor mats that leave the pedal area
unobstructed and that are firmly secured so that they
cannot slip out of position and interfere with the pedals
or impair safe operation of your vehicle in other ways.

WARNING!
Pedals that cannot move freely can cause loss of
vehicle control and increase the risk of serious per-
sonal injury.
•Always make sure that floor mats are properly
attached to the floor mat fasteners.
•Never place or install floor mats or other floor
coverings in the vehicle that cannot be properly
secured to prevent them from moving and inter-
fering with the pedals or the ability to control the
vehicle.
•Never put floor mats or other floor coverings on
top of already installed floor mats. Additional
floor mats and other coverings will reduce the size
of the pedal area and interfere with the pedals.
(Continued)
WARNING! (Continued)
•Check mounting of mats on a regular basis. Al-
ways properly reinstall and secure floor mats that
have been removed for cleaning.
•Always make sure that objects cannot fall into the
driver footwell while the vehicle is moving. Ob-
jects can become trapped under the brake pedal
and accelerator pedal causing a loss of vehicle
control.
•If required, mounting posts must be properly
installed, if not equipped from the factory.
Failure to properly follow floor mat installation or
mounting can cause interference with the brake
pedal and accelerator pedal operation causing loss
of control of the vehicle.

To Raise Rear Seat
Raise the rear seatback and lock it into place. If interfer-
ence from the cargo area prevents the seatback from fully
locking, you will have difficulty returning the seat to its
proper position.
WARNING!
•Be certain that the seatback is securely locked into
position. If the seatback is not securely locked into
position the seat will not provide the proper
stability for child seats and/or passengers. An
improperly latched seat could cause serious injury.
•The cargo area in the rear of the vehicle (with the
rear seatbacks in the locked-up or folded down
position) should not be used as a play area by
children when the vehicle is in motion. They could
be seriously injured in a collision. Children should
be seated and using the proper restraint system.
Reclining Rear Seat
To recline the seatback, lift the lever located on the
outboard side of the seat, lean back and release the lever
at the desired position. To return the seatback, lift the
lever, lean forward and release the lever.
