the engine running depends on the outside

You can then switch on the auxiliary heating
again.
If you do not start the engine for a while, the
total duration of heating is limited to a maxi-
mum of 120 minutes to protect the starter
battery. Switching on the auxiliary heating is
then automatically disabled. You can, for
example, switch on the auxiliary heating with- out the engine running if the outside temper-
ature is 00F85 ‡ (00F820 †) a maximum of two
times. If you try it again, the indicator lamps in
the 0084 button (Y page 123) flash alter-
nately for approximately 2 minutes to signal
switch-on interlock. The auxiliary heating can-
not be switched on without starting the
engine.
When the condition of charge of the starter
battery is sufficient again, the switch-on inter-
lock will be deactivated. To charge the starter
battery, let the engine run. The engine run
time required to reach the necessary condi- tion of charge depends on the outside tem-
perature and on the electrical consumers
switched on. Outside tempera-

WARNING
The auxiliary heating must not be operated if
there are highly flammable substances
nearby or in enclosed spaces without an
extraction system. Make sure that the auxili-
ary heating is not switched on automatically
by the timer in such places. If this possibility
exists, deactivate the respective programmed time.
You can set three preselection times using
the timer.
Observe that when setting the preselection
time, this does not correspond to the switch- on time but to the switch-off or departure
time. The auxiliary heating system starts up
automatically and runs for the operating dura-
tion set prior to departure.
Example: For a planned departure time of
7:00 a.m., you should also set the preselec-
tion time to 7:00 a.m. If the operating dura-
tion is preset to 40 minutes, for example, the
auxiliary heating starts up at 6:20 a.m.
If an identical time (time and day) is set in the preselection memory, only the last time set is
saved.
After a malfunction or if the battery has been disconnected, you must set the preselection
times again. You can find further information
on malfunctions in the "Problems with the
auxiliary heating" section (Y page 132).
