■As soon as the windscreen mists up, press the symbol button . Press the
button  once the windscreen has demisted.■
During operation of the Climatronic, an increase in engine idle speed can oc-
cur under certain circumstances in order to ensure adequate heating comfort.
Efficient handling of the cooling system
Read and observe
and on page 116 first.
The air conditioning system compressor uses power from the engine when in
cooling mode, which will affect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the
interior has been strongly heated through the effect of direct sunlight in order
to allow the heated air to escape.
The cooling system should not be on if the windows are open.
For the sake of the environment
Pollutant emissions are also lower when fuel is being saved » page 136.
malfunctions
Read and observe
and on page 116 first.
If the cooling system does not operate at outside temperatures higher than
+5 °C, there is a problem in the system. The reasons for this may be.
› One of the fuses has blown. Check the fuse and replace if necessa-
ry » page 229 .
› The cooling system has switched off automatically for a short time because
the coolant temperature of the engine is too hot » page 32.
If you are not able to resolve the operational problem yourself, or if the cooler
output has reduced, switch off the cooling system and seek assistance from a
specialist garage.
Auxiliary heating (auxiliary heating and ventilation)
 Introduction
This chapter contains information on the following subjects:
Switching on/off
122
Radio remote control
123Conditions for the functioning of auxiliary heating (auxiliary heating and venti-
lation), hereinafter referred to only as auxiliary heating.
The charge state of the vehicle battery is sufficient.
The fuel supply is adequate (the warning icon 
is not lit in the display of
the instrument cluster).
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).
Auxiliary heating (parking heating)
The auxiliary heating can be used when both when stationary, when the en-
gine is switched off, to preheat the vehicle and also while driving (e.g. during
the heating phase of the engine).
The auxiliary heater functions in connection with the air-conditioning system
or Climatronic.
The auxiliary heating also warms up the engine.
The auxiliary heating warms up the coolant by combusting fuel from the vehi-
cle tank. This heats the air flowing into the passenger compartment (if the
blower is turned on).
The heater is switched on or off automatically depending on the ambient con-
ditions to give the best possible conditions for the engine running and the in-
terior heating.
The automatic switching on and off of the heater can be turned off by a spe-
cialist garage.WARNING■ The auxiliary heating must never be operated in closed rooms (e.g. garag-
es) – risk of poisoning!■
The auxiliary heating must not be allowed to run during refuelling – risk
of fire.
■
The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. If you want to use the heater, do not park the car in places
where the exhaust fumes can come into contact with flammable materials
such as dry grass, undergrowth, leaves, spilled fuel etc. - risk of fire. 
121Heating and air conditioning

CAUTION■The running auxiliary heater consumes fuel from the vehicle tank and auto-
matically controls the filling level. If only a low quantity of fuel is present in the
fuel tank, the auxiliary heating switches off.■
The exhaust pipe of the auxiliary heating, which is located on the underside
of the vehicle, must not be clogged and the exhaust flow must not be blocked.
■
If the auxiliary heating is running, the vehicle battery discharges. If the auxili-
ary heating and ventilation has been operated several times over a longer peri-
od, the vehicle must be driven a few kilometres in order to recharge the vehi-
cle battery.
■
The air inlet in front of the windscreen must be free (e.g. of ice, snow or
leaves) to ensure that the auxiliary heating operates properly.
Note
■ The auxiliary heating switches on the blower B » Fig. 125 on page 119 orC » Fig. 126 on page 119 only if it has achieved a coolant temperature of ap-
prox. 50 °C.■
At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operat-
ing problem.
■
So that warm air can flow into the vehicle interior after switching on the aux-
iliary heating, you must maintain the comfort temperature normally selected
by you, leave the fan switched on and leave the air outlet vents in an open po-
sition. It is recommended to put the air flow in the position 
or 
.
Switching on/off
Fig. 127
Button for switching on/off the system directly on the operating
part of the air conditioning/Climatronic
Read and observe and on page 121 first.
The auxiliary heating can be switched on/off as follows.
Manually switching on Using the button on the operating part of the manual air conditioning/Cli-
matronic. The indicator light in the button illuminates » Fig. 127.
By using the radio remote control » page 123.
Manually switching off Using the button on the operating part of the manual air conditioning/Cli-
matronic. The indicator light in the button goes out » Fig. 127.
By using the radio remote control » page 123.
After switching the system off, the auxiliary heating will continue running a lit- tle while longer in order to burn the remaining fuel in the auxiliary heater.
After switching off the auxiliary heating, the coolant pump still runs for a short
period.
Switching on automatically
The auxiliary heater is switched on according to the Infotainment set-
tings » Infotainment manual , chapter Vehicle settings .
When automatic switching on is activated, the indicator light in the symbol
button  lights up for about 10 seconds after the ignition is turned off.
Switching off automatically
Turning off the auxiliary heating occurs in the following cases.
› The switch-off time set in Infotainment has been achieved
» Operating in-
structions for Infotainment , chapter Vehicle settings .
› The fuel level has reached the reserve area (the warning icon
 illuminates).
› The charge state of the vehicle battery has reduced too much

Switch off the auxiliary heating
The transmitter and the battery are housed in the housing of the remote con-
trol. The receiver is located in the interior of the vehicle.
When the battery is fully charged, the range of the remote control is a few
hundred metres. Obstacles between the radio remote control and the vehicle,
bad weather conditions and a weaker battery can clearly reduce the range.
To switch the auxiliary heating on or off, hold the remote control vertically,
with the aerial
A
» Fig. 128 pointing upwards. The antenna must not be cov-
ered with the fingers or the palm of the hand during this process.
The auxiliary heating can only be switched on/off safely using the radio re-
mote control, if the distance between the radio remote control and the vehicle
is at least 2 m.
After pressing the button, the warning light in the remote control gives the
user different kinds of feedback.

CAUTION
The radio remote control comprises electronic components and must therefore
be protected against water, severe impacts and direct sunlight.123Heating and air conditioning

Note■The battery acid level is also checked regularly by a specialist garage as part
of the inspection service.■
For technical reasons, on vehicles with the description “AGM”, the electrolyte
level cannot be checked.
Charging
Read and observe
and on page 200 first.
A properly charged vehicle battery is essential for reliably starting the engine.
A charging operation can be performed if the following conditions are satis-
fied.
The engine is turned off.
The ignition is switched off.
All consumers are turned off.
The bonnet is open.
“Fast charging” with high currents
›
Disconnect both battery cables (first of all “negative”, then “positive”).
›
Attach the terminal clamps of the charger to the battery terminals (red =
“positive”, black = “negative”).
›
Plug the mains cable of the charger into the power socket and switch on the
device.
›
After charging has been successful: Switch off the charger and remove the
mains cable from the power socket.
›
Only then disconnect the charger's terminal clamps.
›
Reconnect the cables to the battery (first of all “positive”, then “negative”).
Charging with low voltages
It is not necessary to disconnect the cables from the battery if you recharge
the vehicle battery, for example from a mini-charger.
Refer to the instructions of the charger manufacturer .
A charging current of 0.1 multiple of the total vehicle battery capacity (or low-
er) must be used until full charging is achieved.
The vent plugs of the vehicle battery should not be opened for charging.
WARNING■ When you charge a battery, hydrogen is released, and a highly explosive
gas mixture is also produced. An explosion can be caused through sparkling
over during unclamping or loosening of the cable plug while the ignition is
on.■
Creating a bridge between the poles on the battery (e.g. with metal ob-
jects - cables) creates a short circuit - risk of damage to the battery, explo-
sion and burning of the battery, jets of acid spurting out.
■
Avoid creating sparks when working with cables and electrical devices.
Strong sparking represents a risk of injury.
■
Before carrying out any work on the electrical system, switch off the en-
gine, the ignition and all electrical components and disconnect the negative
terminal 
.
■
“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
■
We therefore recommend that vehicle batteries be “rapidly charged” by a
specialist garage.
CAUTION
On vehicles with the START/STOP system or additional heating (auxiliary heat-
ing), do not connect the pole terminal of the charger directly to the negative
terminal of the vehicle battery, but rather only to the engine earth » page 220,
Jump-starting using the battery from another vehicle .
Replacing
Read and observe
and on page 200 first.
The new vehicle battery must have the same capacity, voltage, current and
size as the original battery. Suitable vehicle battery types can be purchased
from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be
disposed of in accordance with national regulations.

202General Maintenance

Towing the vehicle using the towing device is a viable alternative solution to
using the towing eye.
If the towing device is removed completely, it must be replaced with the
standard reinforcement of the rear bumper which is part of the mount for the
towing eye.
If this procedure is not observed, the vehicle may not meet the national legal
provisions.
CAUTION
The detachable ball rod and/or the vehicle can be damaged if an unsuitable
tow bar is used.
