Danger.
RISK OF INJURY. Battery isolating switch
(3) must always be switched off before
any work is carried out on the windscreen
wiper system (wiper blade cleaning, re-
placement of wiper blades or wiper motor
etc.).
Caution:
Observe the following if the batteries
are to be electrically isolated from the
on-board power supply for any reason,
e.g. by operation of the battery isolat-
ing switch: after switching off the engine,
wait at least five minutes before isolat-
ing the battery from the on-board power
supply. This delay is necessary to ensure
fault-free operation of the exhaust gas
cleaning system after the bus has been
restored to operation.
Operation of auxiliary heating
Danger.
Risk of fire and burns. There is a risk of
fires and burns due to the high exhaust
temperatures and the hot exhaust pipe
for the auxiliary heating. For this reason,
do not stop or park the bus over ignitable
materials (e.g. grass) when the auxiliary
heating is in operation, has recently been
in operation or has been operated by the
immediate heating button/preset clock.
Danger.
Risk of poisoning and suffocation. The
auxiliary heating must not be used in en-
closed spaces such as garages or work-
shops due to the risk of poisoning and
suffocation. It must also not be used in
timer or preselection mode.
