Risk of fire and poisoning
The operation of the auxiliary heating pro-
duces hot, toxic exhaust fumes. The fuel
vapours produced during refuelling could
ignite on the hot exhaust system.
Do not switch on the auxiliary heating at
filling stations or in enclosed spaces, for
instance, a garage, if there is no air extrac-
tion system.
You could otherwise endanger yourself and
others.
The Auxiliary heat. function can be called
up directly.

Air conditioning
130 Auxiliary heating/ventilation*
G
Risk of poisoning
Exhaust fumes are produced when the aux-
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
When operating the auxiliary heating, parts
of the vehicle may become very hot, and
highly inflammable material such as fuels
could be ignited. Operating the auxiliary
heating is thus prohibited at filling stations
or when your vehicle is being refuelled. You
must therefore switch off the auxiliary heat-
ing at filling stations.
The auxiliary heating heats the air in the vehi-
cle interior to the set temperature without
using the heat of the running engine. The aux-
iliary heating is operated using fuel directly
from the vehicle's fuel tank. For this reason,
the tank content must be at least at reserve
fuel level to ensure that the auxiliary heating
functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and weather conditions. For this reason, the aux-
iliary heating could switch from ventilation
mode to heating mode or from heating mode
to ventilation mode.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature.
Before activating
X
It is preferable to set the air conditioning to
U.
X Set the temperature.
The auxiliary heating/ventilation can be acti-
vated even when the air conditioning is being
controlled manually. Optimum comfort can
be obtained by activating automatic mode
and setting the temperature to 22 †.
Activating/deactivating the auxiliary
heating/ventilation The auxiliary heating/ventilation can be acti-
vated or deactivated using the remote control
or the button on the centre console.
The on-board computer can be used to spec-
ify up to three departure times, one of which
may be preselected (Y
page 108).
For direct access to the Heatersubmenu in
the on-board computer: X
Make sure that the key is in position 1
or 2in the ignition lock.
X Press the auxiliary heating/ventilation but-
ton for about three seconds.
The auxiliary heating switches off automati-
cally after 50 minutes.
i This time limit can be altered. To do this,
visit a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.

Care
183H
Environmental note
Dispose of empty packaging, cleaning
cloths and polishing wads in an environ-
mentally responsible manner.
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces, otherwise you could
damage the paintwork. Vehicle care
! Do not park the vehicle for a long period
of time directly after cleaning, especially if
the wheels have just been cleaned with a
wheel cleaner. Wheel cleaners could cause
rapid corrosion of the brake discs and
brake pads/linings. After cleaning, park
the vehicle when it is at normal operating
temperature.
Automatic car wash You can wash the vehicle in an automatic car
wash from the beginning. !
Do not use a touch-free automatic car
wash that uses chemical agents to wash
the vehicle.
Preferably use automatic car washes without
brushes.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! Make sure that the automatic car wash is
suitable for the size of the vehicle. Fold in
the exterior mirrors before the vehicle is
washed. There is otherwise a risk of dam-
age to the exterior mirrors.
! Make sure that the side windows are com-
pletely closed, that the ventilation/heater
blower is fully turned off and that the wind-
screen wiper switch is set to 0. The rain
sensor may otherwise be activated, trig-
gering unintended wiper movements. This
could cause damage to the vehicle.
After using an automatic car wash, wipe any
wax and drying agents off the windscreen and
the wiper blades. This will prevent smears and
reduce wiping noises caused by residue on
the windscreen. High-pressure cleaners G
Risk of accident
Do not use high-pressure cleaners with cir-
cular-jet nozzles (dirt grinders) to clean
your vehicle or ― especially ― the tyres.
Otherwise, you could damage the tyres and
cause an accident.
! Observe the instructions issued by the
equipment manufacturer concerning the
distance to be maintained between the
nozzle of the high-pressure cleaner and the
vehicle (at least 30 cm).
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door joint
R electrical components
R battery
R connectors
R lights
R seals
Damaged seals or electrical components
can lead to failures or leaks. Operation
