CAUTIONWe recommend not smoking in the vehicle when the recirculating air operation
is switched on. The smoke sucked from the interior is deposited on the evapo-
rator of the air conditioner. This produces a permanent odour when the air
conditioning system is operating which can only be eliminated through consid-
erable effort and expense (replacement of compressor).

Auxiliary heating (auxiliary heating and ventilation)

The auxiliary heating heats the vehicle interior as well as the engine. For heat-
ing, fuel is consumed from the fuel tank.
The auxiliary ventilation enables fresh air to flow into the vehicle interior with
the engine switched off, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).
The auxiliary heating (auxiliary heating and ventilation) (referred to just as aux- iliary heating in the following) ensures the heating / ventilation depending on
the setting of the air conditioning and the air outlet vents before switching off
the ignition.
108Using the system
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 auxiliary heating, do not park the vehicle
in places where the exhaust fumes can come into contact with flammable
materials such as dry grass, undergrowth, leaves, spilled fuel etc. - There is
a risk of fire.
CAUTION
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 only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.■
In the engine compartment, water vapour may form during the operation of
the heater.

Functional requirements of the auxiliary heating.
The charge state of the vehicle battery is sufficient.
The fuel supply is adequate (the warning light
is not illuminated in the
instrument cluster).
Manual on / off ▶ Using the
button on the control panel of the air conditioning » Fig. 134.
▶ Using the
(switch on) /
(switch off) button on the remote control opera-
tion.
Automatic on / off ▶ Via an automatically programmed and activated pre-set time in Infotainment.
▶ According to the environmental conditions.
Switching off the auxiliary heating takes place automatically when there is a
lack of fuel (warning light in the instrument cluster lights up).
After switching off the system, the coolant pump and the auxiliary heating will
continue running a little while longer in order to burn the remaining fuel in the
heating.
Setting automatic on / off

in the
Infotainment screen. There will be a display of the last set operating mode
with the option to change this.

Then follow the instructions on the Infotainment screen.
When automatic switching on is activated, the warning light in the symbol

Conditions for the system function
The following conditions must be met for the system to function correctly.
The driver's door is closed.
The driver has fastened the seat belt.
The driving speed was higher than 4 km.h after the last stop.
System status
The system status is shown in the display when the vehicle comes to a halt
» Fig. 231 .
The engine is automatically switched off; when the vehicle moves off, the
ignition process will be automatically initiated.
The engine is not automatically switched off.
The engine does not shut down when the vehicle stops, if e.g. the following
applies.
▶ The engine temperature for the proper function of the system has not yet
been reached.
▶ The charge state of the vehicle battery is too low.
▶ The current consumption is too high.
▶ High air conditioning or heating output (high fan speed, big difference be-
tween the desired and actual interior temperature).
If the engine has shut down automatically but the system detects that the en- gine is required to run (e.g. if the brake pedal is pressed repeatedly) then the
system automatically starts up the engine.
More information about the current system status can be displayed in infotain-
ment screen, in the

menu.
If there is a system fault , the following message will appear in the display of
the instrument cluster. Seek help from a specialist garage.
Note
■ If the driver's seat belt is removed for more than 30 seconds or the driver's
door is opened after the engine has switched off automatically, the engine will
have to be restarted manually.■
No automatic engine shut-down takes place when a vehicle with automatic
transmission is moving at low speed (e.g. during a traffic jam) and remains sta-
tionary after pressing the brake pedal lightly. Automatic engine shut-down
takes place if you press the brake pedal down with more force.
■
For vehicles with automatic transmission there is no automatic engine shut-
down when the system detects a manoeuvring action due to a large steering
angle.

Brakes and Parking
Introduction
This chapter contains information on the following subjects:
Handbrake
192
Parking
193
The wear and tear on the brake pads is dependent on the operating condi-
tions and driving style. In difficult conditions (e.g. urban, sporty driving), the
condition of the brakes should be checked between service intervals by a spe-
cialist garage.
Brake response can be slower if the brakes are covered in moisture or, in win-
ter, have a layer of ice or salt on them . The brakes should be cleaned and
dried by applying the brakes many times over »
.
Corrosion on the brake discs and dirt on the brake pads can occur if the vehicle
has been parked for a long period and if you do not make much use of the
braking system. The brakes are cleaned by applying the brakes several times
over »
.
