belt during a collision, do not recline the
seat more than necessary.
If the seat is too rec lined, 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 con-
trol of the vehicle.
