Trailer Warning Lights
For vehicles with auxiliary equipment such as a tow hitch for trailers, an additional
display will also be fitted, as shown. The red LED indicates that the tow-hitch is
OPEN. The green LED indicates that it is closed.
Some manufacturers, such as Scania, have a reset button for the coup-
ling device's servo. This button must be pressed in for the warning for
the coupling device to be deactivated after coupling. If the reset is not car-
ried out, the warning remains active on the LED display and/or driver's
display.
Emergency Stop
In case of an emergency, such as a hydraulic leak or risk of injury, an emergency stop button is fit-
ted to all vehicles.
Pressing the emergency stop button will stop all functions of
the hook-lift immediately. The button is usually placed below
the steering wheel, in the cab.
To reset the emergency stop function, pull the button out,
reset all functions to neutral, then switch off and restart the
vehicle's engine.
