buckle or latch plate is too close to the belt path
opening on the restraint. Disconnect the latch plate
from the buckle and twist the short buckle-end belt
several times to shorten it. Insert the latch plate into
the buckle with the release button facing out.
²If the belt still cannot be tightened, or if pulling and
pushing on the restraint loosens the belt, disconnect
the latch plate from the buckle, turn the buckle
around, and insert the latch plate into the buckle
again. If you still cannot make the child restraint
secure, try a different seating position.
²Buckle the child into the restraint exactly as the
manufacturer's instructions tell you.
²When your child restraint is not in use, secure it in the
vehicle with the seat belt or remove it from the vehicle.
Do not leave it loose in the vehicle. In a sudden stop or
collision, it could strike the occupants or seat backs
and cause serious personal injury.NOTE:For additional information refer to
www.seatcheck.org or call 1-866-SEATCHECK.
Older Children and Child Restraints
Children who weigh more than 20 lbs (9 kg) and who are
older than one year can ride forward-facing in the
vehicle. Forward-facing child seats and convertible child
seats used in the forward-facing direction, are for chil-
dren who weigh 20 to 40 lbs (9 to 18 kg), and who are
older than one year. These child seats are also held in the
vehicle by the lap/shoulder belt or the LATCH child
restraint anchorage system (Refer to LATCH Ð Child
Seat Anchorage System in this section.)
The belt-positioning booster seat is for children weighing
more than 40 lbs (18 kg), but who are still too small to fit
the vehicle's seat belts properly. If the child cannot sit
with knees bent over the vehicle's seat cushion while the
child's back is against the seat back, they should use a

belt-positioning booster seat. The child and belt-
positioning booster seat are held in the vehicle by the
lap/shoulder belt.
Children Too Large for Booster Seats
Children who are large enough to wear the shoulder belt
comfortably, and whose legs are long enough to bend
over the front of the seat when their back is against the
seat back, should use the lap/shoulder belt in a rear seat.
²Make sure that the child is upright in the seat.
²The lap portion should be low on the hips and as snug
as possible.
²Check belt fit periodically. A child's squirming or
slouching can move the belt out of position.
²If 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
their back.
LATCH Ð Child Seat Anchorage System (Lower
Anchors and Tether for CHildren)
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 be
introduced 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.
All three rear seating positions have lower anchorages
that are capable of accommodating LATCH-compatible
child seats having flexible, webbing-mounted lower at-
tachments. Child seats with fixed lower attachments
must be installed in the outboard positions only. Regard-
less of the specific type of lower attachment,NEVER
install LATCH-compatible child seats such that two seats
share a common lower anchorage.If you are installing LATCH-compatible child restraints
in adjacent rear seating positions, you can use the
LATCH anchors or the vehicle's seat belt for the outboard
position, but you must use the vehicle's seat belt at the
center position. If your child restraints are not LATCH-
compatible, you can only install the child restraints using
the vehicle's seat belts. Please refer to the next section for
typical installation instructions.
Installing the LATCH-Compatible Child Restraint
System
We urge that you carefully follow the directions of the
manufacturer when installing your child restraint. Not all
child restraint systems will be installed as described here.
Again, carefully follow the installation instructions that
were provided with the child restraint system.
The rear seat lower anchorages are round bars, located at
the rear of the seat cushion where it meets the seat back,
and are just visible when you lean into the rear seat to

install the child restraint. You will easily feel them if you
run your finger along the intersection of the seatback and
seat cushion surfaces.
In addition, there are tether strap anchorages behind each
rear seating position located on the back of the seat.Many, but not all restraint systems will be equipped with
separate straps on each side, with each having a hook or
connector for attachment to the lower anchorage and a
means of adjusting the tension in the strap. Forward-
facing toddler restraints and some rear-facing infant
restraints will also be equipped with a tether strap, a

hook for attachment to the tether strap anchorage and a
means of adjusting the tension of the strap.
You will first loosen the adjusters on the lower straps and
on the tether strap so that you can more easily attach the
hooks or connectors to the vehicle anchorages. Next
attach the lower hooks or connectors over the top of the
anchorage bars, pushing aside the seat cover material.
Then, locate the tether anchorage directly behind the seat
where you are placing the child restraint and attach the
tether strap to the anchorage, being careful to route the
tether strap to provide the most direct path between the
anchor and the child restraint. 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
Belt
The passenger seat belts are equipped with either cinch-
ing latch plates or automatic locking retractors, which are
designed to keep the lap portion tight around the child
restraint so that it is not necessary to use a locking clip. If
the seat belt has a cinching latch plate, pulling up on the
shoulder portion of the lap/shoulder belt will tighten the
belt. The cinching latch plate will keep the belt tight,
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 65

however, any seat belt system will loosen with time, so
check the belt occasionally and pull it tight if necessary.
For seat belts having an automatic locking retractor, pull
the belt from the retractor until there is enough to allow
you to pass through the child restraint and slide the latch
plate into the buckle. Then, pull the belt until it is all
extracted from the retractor. Allow the belt to return to
the retractor, pulling on the excess webbing to tighten the
lap portion about the child restraint. Refer to ªAutomatic
Locking Modeº earlier in this section.
In the rear seat, you may have trouble tightening the
lap/shoulder belt on the child restraint because the
buckle or latch plate is too close to the belt path opening
on the restraint. Disconnect the latch plate from the
buckle and twist the short buckle-end belt several times
to shorten it. Insert the latch plate into the buckle with the
release button facing out.If the belt still can't be tightened, or if by pulling and
pushing on the restraint loosens the belt, you may need
to do something more. Disconnect the latch plate from
the buckle, turn the buckle around, and insert the latch
plate into the buckle again. If you still can't make the
child restraint secure, try a different seating position.
To attach a child restraint tether strap:
Route the tether strap over the seat back and attach the
hook to the tether anchor located on the back of the seat.
For the outboard seating positions, route the tether over
the head rests, and attach the hook to the tether anchor
located on the back of the seat.
66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
An incorrectly anchored tether strap could lead to
increased head motion and possible injury to the
child. Use only the anchor positions directly behind
the child seat to secure a child restraint top tether
strap.
Transporting Pets
Airbags 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
a collision. 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 engine in
your new vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or 55
mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration, within the
limits of local traffic laws, contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.The engine oil installed in the engine at the factory is a
high quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown in Section 7 of this manual. NON-DETERGENT
OR STRAIGHT MINERAL OILS MUST NEVER BE
USED.
A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered as a normal part of the break-in and not
interpreted as an indication of difficulty.

SAFETY TIPS
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow the safety tips below.
²Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for a extended period. If the vehicle is
stopped in an open area with engine running for more
than a short period, adjust the ventilation system to
force fresh, outside air into the vehicle.
²Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
²Always run the climate control in panel or floor mode
when driving with any windows open, even if only
slightly, to help keep fresh air circulating inside ve-
hicle. Otherwise poisonous gases could be drawn into
the vehicle.
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.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 69

Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.). If there is any question regarding belt or retractor
condition, replace the belt.
Airbag Warning Light
The light should come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch is first
turned on. If the bulb is not lit during starting, have it
replaced. If the light stays on or comes on while driving,
have the system checked by an authorized dealer.
Defrosters
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 inoper-
able.
Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect for tread cuts or sidewall
cracks. Check wheel nuts for tightness and tires (includ-
ing spare) for proper pressure.
Lights
Have someone observe the operation of all exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
coolant, oil or other fluid leaks. Also, if gasoline fumes
are detected, the cause should be located and corrected
immediately.
