Important safety notes This is only for vehicles with a hot-water aux-
iliary heater. G
DANGER
If a switch-on time has been selected, the
auxiliary heating switches on automatically.
R If the ventilation is insufficient, poisonous
exhaust gases can collect, in particular car-
bon monoxide. This is the case in enclosed
spaces, for example. There is a risk of fatal
injuries.
R If highly flammable substances or flamma-
ble materials are nearby, there is a risk of a
risk of fire and explosion.
Always deactivate the preselected switch-on
times if you stop the vehicle in such or similar situations.
Use the timer to: R activate/deactivate immediate heating
mode
R set up to three switch-on times R
set the operating duration from 10to
120 minutes or to continuous operation
R set the heating level (preselected temper-
ature) to a range between 10 and 30

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).

Batteries contain toxic and corrosive substan- ces. If batteries are swallowed, it can result in
severe health problems. There is a risk of fatal injury.
Keep batteries out of the reach of children. If
a battery is swallowed, seek medical attention immediately. H
Environmental note Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately
and recycled to protect the
environment. Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified spe-
cialist workshop or a special
collection point for used bat-
teries.
If the indicator lamp on the remote control
flashes red rapidly, the remote control battery
is discharged. You should replace the remote
control battery.
You need a battery of the type CR2430, which can be obtained at any qualified specialist
workshop. 130
