The seats have manual reclining
seatbacks. The lever used to
operate them is located on the
outboard side of the seats.
To recline the seatback:
1. Lift the recline lever and move
the seatback to the desired
position, then release the lever
to lock the seatback in place.
2. Push and pull on the seatback to
make sure it is locked.
To return the seatback to an upright
position:
1. Lift the lever fully without
applying pressure to the
seatback.
2. Push and pull on the seatback to
make sure it is locked.
Do not have a seatback reclined
when the vehicle is moving.

WARNING
Sitting in a reclined position when
the vehicle is in motion can be
dangerous. Even when buckled
up, the safety belts cannot do
their job when reclined like this.
The shoulder belt cannot do its
job because it will not be against
your body. Instead, it will be in
front of you. In a crash, you could
go into it, receiving neck or other
injuries.
The lap belt cannot do its job
either. In a crash, the belt could
go up over your abdomen. The
belt forces would be there, not at
your pelvic bones. This could
cause serious internal injuries.
For proper protection when the
vehicle is in motion, have the
seatback upright. Then sit well
back in the seat and wear the
safety belt properly.
