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 ride in a moving vehicle with the back-
rest reclined. Sitting in an excessively re-
clined 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. That could cause se-
rious or even fatal injuries. The backrest and
seat belt provide the best restraint when the
wearer is in an upright position and the belt
is properly positioned on the body.
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 re-
strained with a separate seat belt - even
those in the rear.Warning!
G
Read and observe the additional warning no-
tices printed in the “Safety and Security”
section (
page 58) and (
page 60).

Proper use of seat belts


Do not twist the belt when fastening.


Adjust seat belt so that the shoulder
portion is located as close as possible
to the middle of the shoulder (it should
not touch the neck or pass under the
arm). For this purpose, you can adjust
the height of the belt outlet, see below.


Position the lap belt as low as possible
on your hips (over hip joint) and not
across the abdomen.


Place the seat backrest in a nearly up-
right position.


E a c h s e a t b e l t s h o u l d n e v e r b e u s e d f o r
more than one person at a time.


Do not fasten a seat belt around a per-
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.Seat belt height adjustment

the belt runs over the middle of the shoul-
der.

tilated. If you think that exhaust gas fumes
are entering the vehicle while driving, have
