In this case, either deactivate the interior
motion sensor or switch off the auxiliary
heating.

Important safety notes
G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases such as carbon monoxide (CO) may enter the
vehicle. This is the case, for example in
enclosed spaces or if the vehicle gets stuck
in snow. There is a risk of fatal injury.
Switch the auxiliary heating off in enclosed
spaces without extraction systems, e.g. in
garages. If the vehicle is stuck in snow and
you have to leave the auxiliary heating
running, keep the exhaust pipe and the area
around the vehicle free of snow. To ensure an
adequate supply of fresh air, open a window
on the side of the vehicle that is not facing
into the wind. G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot, e.g.
the exhaust system. If flammable materials
such as leaves, grass or twigs remain in
contact with hot parts of the exhaust system
for a prolonged period, they could ignite.
There is a risk of fire.
When the auxiliary heating is switched on,
make sure that no flammable material can
come into contact with hot vehicle
components.
! Switch on the auxiliary heating system at
least once a month for approximately
10 minutes. The auxiliary heating could
otherwise be damaged.
! Make sure that the flow of hot air is not
blocked. The auxiliary heating will
otherwise overheat and switch off.
Your vehicle may be equipped with either an
auxiliary hot-water heater or an auxiliary
warm-air heater. Adjustment and operation of
the:
R hot-water auxiliary heater is done via the
on-board computer and with the auxiliary
heating button in the control panel
(Y page 119) or with the remote control
(Y page 121).
R auxiliary warm-air heater is done via the
timer above the overhead control panel
(Y page 122). 118
