Generator control light
The control light of the generator Fig. 38-67 lights up when the ignition is
switched on, but goes out as soon as the engine is started. If the control
light goes on when the engine is running, this signals: Defect on the V-belt
of the generator or defect in the charge circuit of the generator. The bat-
tery is no longer being charged! Immediately stop the vehicle safely and if
necessary notify an authorised workshop.
Preheat control light
The preheat control light Fig. 38-68 lights up with the ignition switched on.
The engine is preheated until the control light goes out.
If the preheat control light flashes, the preheat procedure has been inter-
rupted and must be repeated.
If the preheat telltale flashes when the key in the ignition switch is in posi-
tion 1, or during slow or fast operation, an error has occurred in the engine
control unit.
USB charging socket
The USB charging socket Fig. 39-30 is used to charge mobile devices
such as tablets, smartphones, navigation devices and digital cameras via
a USB cable.
Windscreen washer unit
The windscreen washer unit is used for cleaning the windscreen.
The water sprayed onto the windscreen supports the cleaning effect of the
windscreen wipers Fig. 39-6.
The windscreen washer unit is supplied from the water tank Fig. 39-34.
Detergents and antifreeze are added to the water as required.
Note
Do not let the windscreen wipers Fig. 39-6 wipe over dry
windscreens for a longer time. Wiper blades wear prema-
turely due to this and the wiper motor can overheat! Switch
the windscreen wipers off with dry windscreens.
The windscreen wiper motor and the water pump are switched on and off
with the switch Fig. 39-65.
The switch has three positions:
•
Position 1: Functions of the windscreen washer unit OFF
•
Position 2: Functions of the windscreen washer unit ON (continuous
mode)
•
Position 3 (pressed briefly): Interval operation ON/OFF
•
Position 3 (pressed longer): Interval operation ON and water pump ON
