Reclining seatback
Sitting in a reclined position when
the vehicle is in motion can be dan-
gerous. Even when buckled up, the
protections of your restraint system
(seat belts and/or air bags) is greatly
reduced by reclining your seatback.
WARNING
NEVER ride with a reclined
OLF034003 seatback when the vehicle is
moving.
Riding with a reclined seatback
increases your chance of seri-
ous or fatal injuries in the event
of a collision or sudden stop.
Drivers and passengers should
ALWAYS sit well back in their
seats, properly belted, and with
the seatbacks upright.
Seat belts must be snug against your
hips and chest to work properly.
When the seatback is reclined, the
shoulder belt cannot do its job
because it will not be snug against
your chest. Instead, it will be in front
of you. During an accident, you could
be thrown into the seat belt, causing
neck or other injuries.
The more the seatback is reclined,
the greater chance the passenger's
hips will slide under the lap belt or
the passenger's neck will strike the
shoulder belt.
