Wiper functions
Automatic activation of the rear window wiper
The rear window wiper is switched on automatically if the front windscreen wipers are switched on
and reverse gear is engaged. The automatic wipe function can be activated and deactivated in the
Infotainment system in the Vehicle settings menu ⇒ Operation and display in the
Infotainment system:
Heated washer jets
The heating defrosts frozen washer jets. The heating output is regulated automatically when the
ignition is switched on depending on the ambient temperature. Only the jets are heated and not the
hoses carrying the washer fluid.
Headlight washer system
The headlight washer system cleans the headlight lenses and only works when the vehicle lighting
is switched on.
Once the ignition has been switched on, the headlights will also be washed the first time the wash
and wipe system for the windscreen is used, and every tenth time thereafter. Hardened dirt, such
as insect remains, should be removed from the headlight lens at regular intervals.
In winter, you should remove any snow from the headlight washer system covers in the bumper
prior to use to keep the system in working order. Remove any ice with a de-icer spray.
Rain/light sensor

Tips and usage notes
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The following tips and operating information will help you use the system correctly.
Why does the cooling system switch off automatically or cannot be
switched on?
•The engine is not running.
•The blower is switched off.
•The air conditioning system fuse has blown.
•The ambient temperature is lower than approximately +3°C (+38°Fyf .
•The air conditioning compressor of the cooling system has been temporarily switched off
because the engine coolant temperature is too high.
•There is a vehicle fault. The air conditioning system should be checked by a qualified workshop.
Settings for optimal road visibility
•Keep the air intake in front of the windscreen free from ice, snow or leaves to improve the
heating and cooling performance and prevent condensation on the windows ⇒ Vehicle care.
•Do not cover the air vents in the rear of the luggage compartment to allow air to flow through
the vehicle from the front to the rear.
•The maximum heating output and the fastest window defrosting results are achieved when the
coolant has reached its operating temperature.
Recommended settings for the heating and fresh air system or manual air
conditioning system

cooling system on.
Recommended Climatronic setup
•Press the button.
•Set the temperature to +22°C (+72°Fyf .
•Open and position the vents on the dash panel.
Air Care Climatronic
The allergen filter of Air Care Climatronic can additionally reduce the amount of pollutants and also
allergens that enter the vehicle interior.
The filters must be changed regularly to avoid impairing the performance of the air conditioning
system. If the vehicle is frequently used in severely polluted air, the filter must be replaced between
service events.
•Press the button on the control panel.
•Touch the Air Care function button.
•Touch the Active function button to switch the Air Care function on or off.
Dust and pollen filter
The dust and pollen filter must be replaced regularly to prevent impaired performance of the manual
air conditioning system. If the vehicle is frequently used in severely polluted air, the filter must be
replaced between service events.
Water under the vehicle
If the humidity and temperature outside the vehicle are high, condensation can drip off the
evaporator in the cooling system and form a pool underneath the vehicle. This is normal and does
not indicate a leak.
If the outside humidity is high and the outside temperature low, condensation may evaporate when
the auxiliary heater is running ⇒ Auxiliary heater and ventilation. If this is the case, steam may
appear underneath the vehicle. This is not a sign that the vehicle is damaged.
Auxiliary heater and ventilation
Introduction
This chapter contains information on the followingsubjects:
⇒ Switching the auxiliary heater and auxiliary ventilation on and off
⇒ Programming the auxiliary heater and auxiliary ventilation
⇒ Remote control
Switching on start/stop
The function is automatically activated every time the ignition is switched on. The instrument cluster
display will show information about the current status.
Vehicles with DSG dual clutch gearbox may be equipped with a start/stop system with engine-off
coasting function. The engine-off coasting function is deactivated and activated together with the
start/stop system.
Further information regarding start/stop mode is available in the Infotainment system ⇒ Operation
