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
restrained with a separate seat belt.Warning!

Read and observe the additional warning no-
tices printed in the “Safety and Security”

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.
