Switch the auxiliary heating on regularly once a
month for about ten minutes.
The auxiliary heating heats the air in the vehicle interior to the set temperature. This occurs with-out using the heat of the running engine. The
auxiliary heating is operated directly using the
vehicle's fuel. For this reason, the tank content
must be at least at reserve fuel level to ensure
that the auxiliary heating functions.
The auxiliary heating or auxiliary ventilation
automatically adjusts to changes in tempera-
ture and weather conditions. For this reason,
the auxiliary heating could switch from ventila-
tion mode to heating mode or from heating
mode to ventilation mode.
The auxiliary heating switches off when the
engine is switched off. The auxiliary ventilation
switches off when you turn the key to position 2
(Y page 148).
The auxiliary heating switches off automatically
after 50 minutes. This time limit can be altered.
To do this, visit a qualified specialist workshop.
You cannot use the auxiliary ventilation to cool
the vehicle interior to a temperature lower than
the outside temperature.
Before switching on X
Turn the key to position 2in the ignition lock
(Y page 148).
X Set the desired temperature.
The auxiliary heating/ventilation can be activa-
ted even when climate control is set to manual.
Optimum comfort can be attained when the sys-
tem is set to automatic mode. Set the temper-
ature to 22 †.
The auxiliary heating or auxiliary ventilation can
be switched on/off using the button on the
centre console or the remote control.
The on-board computer can be used to specify
up to three departure times, one of which may
be preselected (Y page 253). Switching the auxiliary heating/venti-
lation on or off using the button on the
centre console General notes
The colours of the indicator lamps in button
:
mean the following:
R blue: auxiliary ventilation is switched on
R red: auxiliary heating is activated
R yellow: departure time is preselected
(Y page 253).
Switching on/off X To switch on the auxiliary heating or aux-
iliary ventilation:
press button:.
The red or blue indicator lamp in button :

Switching the auxiliary heating/venti-
lation on or off using the remote control General notes
Your vehicle comes with one remote control.
You may use two additional remote controls for
your vehicle. For more information, please con-
tact a qualified specialist workshop.
Store the remote control for the auxiliary heat-
ing so that the auxiliary heating cannot be
switched on unintentionally. In particular,
ensure that the remote control for the auxiliary
heating is kept out of the reach of children. Operating the climate control system

Important safety notes
G
WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet grille on the bonnet and in
the engine compartment on the front-
passenger side free of blockages, such as ice,
snow or leaves.
R never cover the vents or ventilation grilles in
the vehicle interior i
For virtually draught-free ventilation, adjust
the sliders of the air vents to the centre posi- tion. Adjusting the centre air vents

Before attempting to start the engine again:
X Turn the key back to position 0in the ignition lock.
or X Press the Start/Stop button repeatedly until all indicator lamps in
the instrument cluster go out.
X Try to start the engine again (Y page 149). Avoid excessively long
and frequent attempts to start the engine, as this will drain the
battery.
If the engine does not start after several attempts:
X Consult a qualified specialist workshop. The engine does not
start. The starter motor
can be heard. The
reserve fuel warning
lamp is lit and the fuel
gauge display shows
0. The fuel tank is empty.
X Refuel the vehicle. The engine does not
start. You cannot hear
the starter motor. The on-board voltage is too low because the battery is too weak or
discharged.
X Jump-start the vehicle (Y page 354).
If the engine does not start despite attempts to jump-start it:
X Consult a qualified specialist workshop. The starter motor was exposed to a thermal load that was too high.
X Allow the starter motor to cool down for approximately two minutes.
X Try to start the engine again.
If the engine still does not start: X Consult a qualified specialist workshop. Vehicles with a petrol
engine:
The engine is not running
smoothly and is misfir-
ing. There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
X Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it.
X Have the cause rectified immediately at a qualified specialist work-
shop. 154

WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving.
Drive sensibly – save fuel Observe the following tips to save fuel:
X The tyres should always be inflated to the rec-
ommended tyre pressure.
X Remove unnecessary loads.
X Remove roof carriers when they are not nee-
ded.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the Ser-
vice Booklet or by the service interval display.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic, on short jour- neys and in hilly terrain. ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists you in achieving the most economical driving style
for the selected settings and prevailing condi-
tions. Consumption can be significantly influ-
enced by your driving style. :
