Children 12 years old and under must be
seated and properly secured in an appropri-
ate infant, or toddler restraint, or booster
seat recommended for the size and weight
of the child. For additional information, see
“Children in the vehicle” (

A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.

Adjust head restraint so that the head
restraint supports the back of the head at
eye level. This will reduce the potential for
injury to the head and neck in the event of
an accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are in-
tended to help reduce injuries during an
accident.
iAdjust the head restraint in such a way that

trol of the vehicle.Warning!G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
terior rear view mirror or glance over your
shoulder before changing lanes.

forcibly pushed forward (hit from the rear) or
rearward (hit from the front), reposition it by
applying firm pressure until it snaps into place.

48 Getting started
Driving
Fastening the seat belts
Warning!G
Make sure that absolutely no objects are ob-
structing the pedal’s range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure the pedals still have
sufficient clearance.
During sudden driving or braking maneu-
vers, the objects could get caught between
the pedals. You could then no longer brake
or accelerate. This could lead to accidents
and injury.Warning!G
Always fasten your seat belt before driving
off. Always make sure your passenger is
properly restrained.
Failure to wear and properly fasten and
position your seat belt greatly increases
your risk of injuries and their likely severity
in an accident. You and your passenger
should always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are wearing your
seat belt. The air bags can only provide the
protection they were designed to afford if
the occupants are using their seat belts
(
page 64).
Warning!G
Children 12 years old and under must be
seated and properly secured in an appropri-
ate infant, or toddler restraint, or booster
seat recommended for the size and weight
of the child. For additional information, see
“Children in the vehicle” (
page 79).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.

3Release button
4Buckle
With a smooth motion, pull the seat
belt from the seat belt outlet.
Place the shoulder portion of the seat
belt across the top of your shoulder
and the lap portion across your hips.
Push latch plate2 into buckle4 until
it clicks.
If necessary, tighten the lap portion to
a snug fit by pulling shoulder portion
up.
For more information, see “Safety guide-
lines for the seat belt, emergency tension-
ing device and air bag” (
page 68).
Warning!G
Never let more people ride in the vehicle
than there are seat belts available. Be sure
everyone riding in the vehicle is correctly
restrained with a separate seat belt. Never
use a seat belt for more than one person at
a time.
Warning!G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the seat belt would apply force at
the abdomen or neck. That could cause
serious or even fatal injuries. The seat back-
rest and seat belt provide the best restraint
when the wearer is in a position that is as
upright as possible and the seat belt is
properly positioned on the body.
Warning!G
Read and observe the additional warning no-
tices printed in the “Safety and Security”
section (
page 68) and (page 76).
