restarts automatically in the following situa‐
tions:
▷Very high temperature inside the passen‐
ger compartment, if the cooling function is

wheel.▷M double clutch transmission: Shift from
selector lever position D to N, R or D/S.▷M double clutch transmission: Depress the
accelerator and the brake at the same time.▷Vehicle starts to roll.▷Condensation when the automatic air con‐
ditioning is switched on.▷Vehicle battery is very low.▷Very low temperature inside the passenger
compartment, if the heating is on.▷Low brake vacuum, for example because

Air conditioning functions in detailSwitching system on/off
Switching on
Press any key, except▷Heated rear window.▷Seat heating
Switching off
In the lowest setting, press the left of
the button.
Temperature Turn the wheel to select the de‐
sired temperature.
The automatic air conditioning sets this tem‐ perature as quickly as possible, using higher
cooling or heating power if necessary. The
temperature is then maintained.
Avoid switching between different temperature
settings in rapid succession. The automatic air
conditioning will not then have sufficient time
to establish the temperature selected.
Cooling function
The interior can only be cooled when the en‐
gine is running.
Press the button.
Air is cooled and dried, then reheated
to suit the temperature setting.
Depending on weather conditions, the wind‐
screen and side windows may mist over mo‐
mentarily when the engine is started.
The cooling function is switched on automati‐
cally in the AUTO program.
When using the automatic air conditioning,
condensation water, see page 165, develops
that exits underneath the vehicle.
Maximum cooling effect Press the button.
System is set to lowest temperature,
optimum air flow and recirculated-air mode.
The air flows from the outlets for the upper
body area. Therefore open the ventilation vents.
The function is available through an outside
temperature of approximately 0 ℃/32 ℉ and
with the engine running.
The air flow can be adapted when the program
is active.
AUTO program Press the button.
The air flow, air distribution and tem‐
perature are automatically regulated.
Depending on the selected temperature, inten‐
sity AUTO program and external influences,
the air is directed towards the windscreen, side
windows, upper body, and into the footwell.
The cooling function, see page 145, is
switched on automatically in the AUTO pro‐
gram.
A condensation sensor also controls the pro‐
gram so that condensation is avoided as much
as possible.
Intensity of AUTO program
When AUTO program is switched on, auto‐
matic control of the intensity can be changed.
Pressing the button on the left or right
reduces or increases intensity.
The selected intensity is shown on the display
for automatic air conditioning.Seite 145ClimateControls145

Automatic air recirculation control,
AUC/recirculated-air mode
If the air outside the vehicle has an unpleasant
odour or contains pollutants, the supply to the
interior of the vehicle can be shut off. The air
inside the vehicle is then recirculated.
Press button repeatedly to call up an
operating mode:▷LEDs off: ambient air is constantly entering
the car.▷Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air and
shuts it out automatically.▷Right-hand LED on, recirculated-air mode:
the ambient air supply is permanently shut
off.
The recirculated-air mode automatically
switches off at low outside temperatures after
a given time, to avoid condensation.
Continuous recirculated-air mode deteriorates
the air quality in the interior and condensation
on the windows increases.
If there is condensation on the window, switch
off recirculated-air mode and press the AUTO
button to use the condensation sensor. Ensure
that air can flow towards the windscreen.
Adjusting the air flow manually To be able to adjust the air flow manually, first
switch off the AUTO program.
Pressing the button on the left or right
reduces or increases the air flow.
The selected air flow is shown on the display
for automatic air conditioning.
In order to protect the battery the air flow rate
of the automatic air conditioning is reduced, if
necessary.
Adjusting the air distribution manually Press button repeatedly to select a
program:
▷Upper body area.▷Upper body area and footwell.▷Footwell.▷Windows and footwell: only on the driver's
side.▷Windows, upper body area and footwell:
only on the driver's side.
If there is condensation on the window, press
the AUTO button in order to use the conden‐
sation sensor.
Defrosting windows and removing
condensation
Press the button.
This removes ice and condensation
quickly from the windscreen and the front side
windows.
To do this, point the side nozzles at the side
windows if necessary.
The air flow can be adapted when the program
is active.
If there is condensation on the window, switch
on the cooling function as well or press the AUTO button to use the condensation sensor.
Heated rear window Press the button.
The heated rear window is switched
off automatically after a certain period of time.
Microfilter/activated charcoal filter
In outside and recirculated-air mode, the mi‐
crofilter/activated carbon filter filters dust, pol‐ len and harmful gases from the air.
This filter should be changed during mainte‐
nance on your vehicle, see page 191.

Independent ventilation
Principle The independent ventilation system ventilates
the passenger compartment and lowers its
temperature under some circumstances.
The system can be switched on and off at any
ambient temperature either directly or via two
preselected switch-on times. It remains
switched on for 30 minutes.
Open the ventilation vents so the air can flow

General
The vehicle has two coolant tanks located in
the engine compartment.
To guarantee operational safety of the vehicle,
always check the coolant levels of both coolant
tanks.
Notes WARNING
If the cooling system is opened when the
engine is hot, coolant can escape and cause
scalds. Danger of injury. Only open the cooling
system when the engine has cooled down.◀
WARNING
Additives are harmful to health and incor‐
rect additives can damage the engine. Danger
of injury and damage to property. Do not allow
additives to come into contact with clothing,
skin or eyes, and do not swallow them. Only
use suitable additives.◀
Coolant is a mixture of water and an additive.
Not all commercially available additives are
suitable for the vehicle. Information regarding
suitable additives is available from a Service
Partner or a qualified specialist workshop.Coolant level
Overview
Depending on the engine version, the coolant
tank is located on the right or left of the engine
compartment.
Checking1.Allow the engine to cool down.2.Turn cap on coolant tank slightly anti-
clockwise until it starts to open, then allow
the pressure to escape.3.Open cap on coolant tank.4.The coolant level is correct if it is between
the Min. and Max. marks in the filler neck.
