To reduce the risk of sliding under the lap
belt during a collision, do not recline the
seat more than necessary.
If the seat is too reclined, the lap belt may
slide past the hips and apply restraint
forces directly to the abdomen, or your
neck may contact the shoulder belt,
increasing the risk of death or serious
injury in the event of an accident.
Adjustments should not be made while
driving as the seat may unexpectedly
move and cause the driver to lose control
of the vehicle.

belt cannot be fitted properly, and they
may be thrown from the seat, resulting in
death or serious injury in the event of an
accident or sudden braking.

retract the ottoman. If the ottoman is
not retracted, it may cause a fall, result-
ing in injury.
●Do not operate the ottoman when the
vehicle is moving.

or feet under the re ar seat when stow-
ing the ottoman.
