EMERGENCY OFF switch

Vehicles used to transport hazardous goods are equipped with two EMERGENCY OFF switches. The switches
are used to interrupt the power supply in an emergency. This prevents short circuits with sparks which may
ignite a fire or an explosion.
Risk of accident
Press the EMERGENCY OFF switch only in the event of danger and only when the vehicle is stationary; never
while driving. The EMERGENCY OFF switch kills the engine automatically, i.e. the power steering is
inoperative as well. The vehicle can only be steered with increased effort.
