4Release button
With a smooth motion, pull the belt
from the seat belt outlet1.
Place the belt over your shoulder.
Push the latch plate2 into the buckle3
until it clicks.
If necessary, tighten the lap portion to
a snug fit by pulling shoulder portion
up.
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).
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.
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 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. That 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
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.
Warning!
G
Read and observe the additional warning no-
tices in the “Safety and Security” section
(page 58).

Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
