WARNING!
•For personal security and safety in the event of an
accident, lock the vehicle doors before you drive as
well as when you park and leave the vehicle.
•When leaving the vehicle, always remove the key
from the ignition and lock your vehicle. Unsuper-
vised use of vehicle equipment may cause severe
personal injuries and death.
•Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Don’t leave the key in
the ignition. A child could operate power win-
dows, other controls, or move the vehicle.

28 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
Infants in rear-facing child restraints should NEVER
ride in the front seat of a vehicle with a passenger
front airbag. An airbag deployment could cause
severe injury or death to infants in that position.
2. Children who are not big enough to wear the vehicle
seat belt properly should be secured in the rear seat in
child restraints or belt-positioning booster seats. (Refer to
information on Child Restraints in this section.)
3. Older children who do not use child restraints or
belt-positioning booster seats should ride properly buck-
led up in the rear seat. Never allow children to slide the
shoulder belt behind them or under their arm.
4. If a child from 1 to 12 years old must ride in the front
passenger seat because the vehicle is crowded, move theseat as far back as possible and use the proper child
restraint. (Refer to information on Child Restraints in this
section.)
5. You should read the instructions provided with your
child restraint to make sure that you are using it properly.
6. All occupants should use their seat belts properly.
7. The driver and front passenger seats should be moved
back as far as practical to allow the airbags time to inflate.
8. If your vehicle has supplemental side curtain airbags
and/or supplemental front seat-mounted side airbags,
do not lean against the door, as the airbags will inflate
forcefully into the space between you and the door.
9. If the airbag system in this vehicle needs to be
modified to accommodate a disabled person, contact the
Customer Center. Phone numbers are provided in theIf
You Need Customer Assistancesection.

Child Restraints
Everyone in your vehicle needs to be buckled up all the
time, including babies and children. Every state in the
United States and all Canadian provinces require that
small children ride in proper restraint systems. This is the
law, and you can be prosecuted for ignoring it.
Children 12 years and younger should ride properly
buckled up in a rear seat, if available. According to crash
statistics, children are safer when properly restrained in
the rear seats rather than in the front.
WARNING!
In a collision, an unrestrained child, even a tiny baby,
can become a missile inside the vehicle. The force
required to hold even an infant on your lap could
become so great that you could not hold the child, no
matter how strong you are. The child and others
could be badly injured. Any child riding in your
vehicle should be in a proper restraint for the child’s
size.
There are different sizes and types of restraints for
children from newborn size to the child almost large
enough for an adult safety belt. Always check the child
seat Owner’s Manual to ensure you have the correct seat
for your child. Use the restraint that is correct for your
child.
66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Here are some tips on getting the most out of your child
restraint:
•Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable Safety
Standards. We also recommend that you make sure
that you can install the child restraint in the vehicle
where you will use it before you buy it.
•The restraint must be appropriate for your child’s
weight and height. Check the label on the restraint for
weight and height limits.
•Carefully follow the instructions that come with the
restraint. If you install the restraint improperly, it may
not work when you need it.
•Buckle the child into the seat according to the child
restraint manufacturer’s directions.
•When 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 seatbacks and
cause serious personal injury.
LATCH — 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
have features for installation using the vehicle’s seat
belts. Child restraints having tether straps and hooks for

Seat belts with an automatic locking retractor have a
distinctive label on the seat belt webbing. The seat belt
must be in the Automatic Locking mode in order to
enable a child restraint to be tightly installed. Refer to
“Automatic Locking Mode” in this section. A locking clip
should not be necessary once the automatic locking
feature is enabled. Position the shoulder and lap belt on
the child restraint. The automatic locking retractor is
activated by first attaching the child seat, then pulling all
of the webbing out of the retractor, then allowing the
webbing to retract back into the retractor. Tighten web-
bing. To release, simply unbuckle the seat belt by de-
pressing the button, allowing the webbing to retract into
the retractor.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 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:
1. Rotate the cover over the anchor directly behind the
seat where you are placing the child restraint.
2. Route the tether strap to provide the most direct path
for the strap between the anchor and the child seat.3. Attach the tether strap hook (A) of the child restraint to
the anchor (B) and remove slack in the tether strap
according to the child restraint manufacturer’s instruc-
tions.
NOTE:Ensure that the tether strap does not slip into the
opening between the seatbacks as you remove slack in
the strap.
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 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 under “Engine Oil”, under “Maintenance Proce-
dures” 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.
