41 Getting started
Driving
The seat belt presenter for driver and pas-
senger makes it easier to put on the seat
belt.
1Seat belt presenter
The seat belt presenter slides out when the
corresponding door is closed and the
SmartKey in the starter switch or
KEYLESS-GO* start/stop button are in
position1 or2.
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing positions. Infants and small children
must ride in back seats and be seated in an
appropriate infant or child restraint system,
which is properly secured with the vehicle's
seat belt or lower anchors, fully in accor-
dance with the child seat manufacturer's
instructions.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.Warning!
G
Never let more people ride in the vehicle
than there are seat belts available. Make
sure everyone riding in the vehicle is cor-
rectly restrained with a separate seat belt.
Warning!
G
Never ride in a moving vehicle with the seat
backrest reclined. Sitting in an excessively
reclined position can be dangerous. You
could slide under the seat belt in a collision.
If you slide under it, the belt would apply
force at the abdomen or neck. This could
cause serious or even fatal injuries. The seat
backrest and seat belt provide the best re-
straint when the wearer is in an upright po-
sition and the 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 62).

Proper use of seat belts

on your hips (over hip joint) and not
across the abdomen.
Place the seat backrest in a nearly up-
right position.

son and another object at the same
time.
Check your seat belt during travel to
ensure that it is properly positioned.
Ensure that the seat belt is always fit-
ted snugly. You should avoid wearing
bulky clothing, such as winter coats,
when traveling in the vehicle.
