Failure to do so may result in death or serious injury.●
Do not adjust the position of the driver’s seat while driving.
Doing so could cause the driver to lose control of the vehicle. ●

injured by the moving seat. ●
Do not put your hands under the seat or near the moving parts to avoid injury.

of death or serious injury in the event of an accident.
Adjustments should not be ma de while driving as the seat may unexpectedly move and
cause the driver to lose control of the vehicle.
