Checking programming
If the timer has been switched on after switching the ignition off, the instant
on button will remain lit for around ten seconds.
WARNING
Never program the independent heating system to be activated and oper-
ated in closed, unventilated areas. The auxiliary heater fumes contain carbon dioxide, an odourless and colourless toxic gas. Carbon monoxide
can cause people to lose consciousness. It can also cause death.
User instructions
The auxiliary heater exhaust system located below the vehicle must be kept
clear of snow, mud and other objects. The exhaust fumes must not be
obstructed in any way. The exhaust fumes generated by the auxiliary heater
are removed via an exhaust pipe fitted underneath the vehicle.
On heating the vehicle interior, depending on the outside temperature the
warm air is first directed at the windscreen and then to the rest of the
passenger compartment through the air vents. If the air vents are turned
towards the windows, for example, the form of air distribution may be
affected.
Depending on the outside temperature, the temperature at which the auxil-
iary heater warms the vehicle interior may be somewhat higher if the heating
or climate control temperature control is set to maximum before switching the
heating on.
Depending on the engine, vehicles with auxiliary heater may be fitted with a
second battery in the luggage compartment that is responsible for powering
the auxiliary heater.
Cases in which the auxiliary heater will not switch on
xThe auxiliary heater requires about as much power as the dipped head-
lights. If the battery charge is low, the auxiliary heater will switch off automat-
ically or will not even switch on. This avoids problems when starting the
engine.
xThe heater will switch just once each time. The timer will also have to be
switched back on every time it is required.
