iliary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You
should therefore switch off the auxiliary
heating in confined spaces without an
extraction system, e.g. a garage. G
Risk of fire

Switching the auxiliary heating/venti-
lation on/off using the remote control Your vehicle comes with one remote control.
You may use two additional remote controls
for your vehicle. For further information, con-
sult a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
The remote control has a maximum range of
approximately 300 metres. This range may be
reduced by:
R sources of radio interference
R solid objects between the remote control
and the vehicle
R the remote control being in an unfavoura-
ble position in relation to the vehicle
R transmitting from an enclosed space
i The optimum range can be achieved if you
hold the remote control vertically, pointing
upwards when you press one of the but-
tons.
i A battery symbol appears in the display
when the batteries in the remote control
are low. Replace the remote control bat-
teries (Y page 305). i
More information about the auxiliary
heating can be found in the "Practical
advice" section (Y page 300). Auxiliary heating remote control
