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
123Conditions 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
» page 200.
122Using the system
Artificial leather, materials and Alcantara®
Read and observe
and on page 186 first.
Artificial leather
Clean artificial leather with a damp cloth.
If this method does not completely clean the artificial leather, use a mild soap
solution or cleaning products specially designed for this purpose.
Fabric
Clean upholstery cover materials and cloth trims on doors, luggage compart-
ment cover, etc. using specific cleaning agents, e.g., dry foam.
Use a soft sponge, brush, or commercially available microfibre cloth.
Use a cloth and a cleaning agent specifically designed for this purpose to clean the roof trim.
Remove any lumps on the cover fabric and any fabric residue using a brush.
Remove stubborn hair using a “cleaning glove”.
Alcantara ®
Dust and dirt in pores, creases and seams may chafe and damage the surface.
Therefore, they must be removed regularly at short intervals with a cloth or
vacuum cleaner.
Minor changes in colour caused by use are normal.
CAUTION
■ For Alcantara ®
seat covers, do not use any solvents, floor wax, shoe cream,
stain remover, leather cleaners or similar agents.■
Avoid leaving the vehicle in bright sunlight for long periods of time in order
to stop the artificial leather, materials or Alcantara ®
from bleaching. During ex-
tended periods of standing outdoors, protect artificial leather, fabrics or Alcan-
tara ®
by covering.
■
Some clothing materials, e.g. dark denim, do not have sufficient colour fast-
ness. This can cause damage or clearly visible discolouration to seat covers,
even when used correctly. This applies particularly to light-coloured seat cov-
ers. This does not relate to a fault in the seat cover, but rather to poor colour
fastness of the clothing textiles.
Seat covers
Read and observe
and on page 186 first.
Electrically heated seats
Use a specific cleaning agent such as dry foam or similar to clean the cov-
ers. »
.
Seats without seat heating
Thoroughly vacuum the seat covers with a vacuum cleaner before cleaning.
Clean the seat covers with a damp cloth or cleaning products specially de-
signed for this purpose.
Indented points arising on the fabrics by everyday use, can be removed by
brushing against the direction of hair with a damp brush.
Always clean all parts of the covers, so that there are no visible edges. Then
allow the seat to dry completely.
CAUTION
■ Do not clean the covers of electrically heated seats either with water or with
other liquids - there is a risk of damaging the seat heating system.■
Regularly remove dust from the seat covers using a vacuum cleaner.
■
Electrically heated seats must not be dried after cleaning by switching on the
heater.
■
Do not sit on wet seats - risk of seat deformation.
■
Always clean the seats from “seam to seam”.
Safety belts
Read and observe
and on page 186 first.
Wash dirty seat belts with mild soapy water.
Remove coarse dirt with a soft brush.
WARNING■ The seat belts must not be removed for cleaning.■Never clean the seat belts chemically as chemical cleaning products could
destroy the fabric.■
The seat belts must not be allowed to come into contact with corrosive
liquids (e.g. acids).
■
The seat belts must be fully dried before being rolled up.
187Care and maintenance
WARNING (Continued)■If coolant is swallowed, consult a doctor immediately.■Never spill operating fluids over the hot engine - risk of fire.
CAUTION
■If for some reason it is not possible to top up the coolant under the current
circumstances, do not continue driving! Switch off the engine and seek as-
sistance from a specialist garage.■
If the expansion tank is empty, do not top up with coolant. The system could
aerate - risk of engine damage,
do not continue driving! Switch off the en-
gine and seek assistance from a specialist garage.
■
The amount of coolant additive in the coolant must never be allowed to be
less than 40 %.
■
Over 60 % of coolant additive in the coolant reduces the antifreeze protec-
tion and coolant effectiveness.
■
A coolant additive that does not comply with the correct specification can
significantly reduce the corrosion protection of the cooling system.
■
Any faults resulting from corrosion may cause a loss of coolant and can con-
sequently result in major engine damage!
■
Do not fill the coolant above the mark
A
» Fig. 188 on page 198 .
■
If an error occurs, leading to the engine overheating, the help of a professio-
nal garage is to be sought - there is a risk of serious engine damage occurring.
■
Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.
■
Never cover the radiator - there is a risk of the engine overheating.
Note
On vehicles that are fitted with an auxiliary heater (auxiliary heating and venti-
lation), the coolant capacity is approx. 1 l larger.

.
The coolant can be checked and topped up, if the following conditions are sat-
isfied.
The vehicle is standing on a horizontal surface.
The engine is turned off.
The engine is not heated.
The bonnet is open.
Checking the level
›
Check the coolant level in the coolant expansion tank » Fig. 188.
If the engine is warm, the test result may be inaccurate. The level can also be
above the mark
A
» Fig. 188 .
In the event of an insufficient coolant level, the control symbol is displayed
in the instrument cluster as well as the relevant notification » page 41. We still
recommend inspecting the coolant level directly at the expansion tank from
time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the cooling sys-
tem. Do not merely top up the coolant. Have the cooling system checked by a
specialist garage.
Replenishing
Read and observe
and on page 197 first.
The coolant expansion tank must always contain a small amount of cool-
ant » page 198, in section Introduction .
›
Place a cloth over the cap of the coolant expansion reservoir and unscrew
the cap carefully .
›
Replenish the coolant.
›
Turn the cap until it clicks into place.

CAUTION
■ Disconnect the vehicle battery only with the ignition turned off - there is a
risk of damaging the electrical system of the vehicle.■
Under no circumstances must the battery cables be connected incorrectly –
risk of a cable fire.
Note
■ After disconnecting and re-connecting the vehicle battery, we recommend
having the vehicle checked by a specialist to ensure that the full functionality
of all electrical systems is guaranteed.■
The data of the multi-function display will be reset.
Automatic load deactivation
Read and observe
and on page 200 first.
The vehicle voltage control unit automatically prevents the battery from dis-
charging when the bettery is subjected to heavy loads. This manifests itself by
the following.
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where appropriate large convenience consumers, e.g. seat heaters, rear win-
dow heaters, have their power limited or in case of emergency shut off com-
pletely.
CAUTION
■ Despite such intervention by the vehicle electric system management, the
vehicle battery may be drained. For example, when the ignition is switched on
a long time with the engine turned off or the side or parking lights are turned
on during longer parking.■
Consumers which are supplied via a 12 V socket can cause the vehicle battery
to discharge when the ignition is switched off.
Note
Driving comfort is not disrupted by any shutting off of consumers. Often the
driver is not aware of it having taken place.203Inspecting and replenishing
