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
•Switch off air recirculation mode.
•Set blower to setting or .
•Set the temperature selector to the middle position.
•Open and position all vents on the dash panel.
•Turn the air distribution regulator to the desired position.

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

The auxiliary heater and ventilation
system allows the vehicle interior to be
heated in winter and ventilated in
summer. Operation of the system
allows ice, condensation and a thin
covering of snow to be cleared from the
windscreen. The auxiliary heater is
supplied with fuel from the vehicle fuel
tank and can be operated when the
vehicle is stationary with the ignition
switched off. The auxiliary ventilation
system is supplied with power by the
12-volt vehicle battery.
Auxiliary heater exhaust system
The emissions produced by the auxiliary heater are removed via an exhaust pipe fitted underneath
the vehicle. The exhaust pipe must not be blocked by snow, mud or other objects.
Switching the auxiliary heater and auxiliary ventilation on and off
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The auxiliary heating can be operated only when the ignition is switched off. If the ignition is
switched on while the auxiliary heater is working, the auxiliary heater continues to run to provide
additional heat.
Switching on the auxiliary heater
•Press the immediate heat button on the control panel ⇒ Front controls.
•Press the button on the remote control ⇒ Remote control.
•Program a departure time ⇒ Programming the auxiliary heater and auxiliary ventilation.
The auxiliary heater heats up the vehicle interior to a temperature of at least 22°C.
The auxiliary heater will not switch on if the 12-volt vehicle battery has a low charge level or the fuel
tank is empty.
Switching off the auxiliary heater manually
•Press the immediate heat button on the control panel ⇒ Front controls.
•Press the button on the remote control ⇒ Remote control.
•Touch the function button in the Infotainment system ⇒ Programming the auxiliary heater 
and auxiliary ventilation.
Auxiliary heater switches off automatically
•When the programmed departure time is reached, or after the programmed operating period
has elapsed ⇒ Programming the auxiliary heater and auxiliary ventilation.
•If the indicator lamp or lights up (fuel gaugeyf ⇒ Fuel gauge.
•If the charge level of the 12-volt vehicle battery is too low ⇒ 12-volt vehicle battery.
The fumes from the auxiliary heater contain among other things carbon monoxide, which
is an odourless and colourless poisonous gas. Carbon monoxide can cause people to
lose consciousness. It can also cause death.
•Never start or run the auxiliary heater in unventilated or closed rooms.
•Never programme the auxiliary heater so that it is switched on and run in unventilated
or enclosed spaces.
WARNING
Parts of the auxiliary heater exhaust system become very hot. This can cause fires.
•Park the vehicle so that no part of the exhaust system can come into contact with any
inflammable material underneath the vehicle, e.g. dry grass.
WARNING
Do not place any food, medicine or any other temperature-sensitive items in front of the
vents. Heat-sensitive food, medicine and other items could be either damaged or rendered
useless.
NOTICE

The auxiliary heater runs on for a short time after it is switched off manually or automatically so that
the remaining fuel in the system can be burnt off.
When the vehicle is at a standstill, the auxiliary heater can be activated up to three times in
succession for the maximum operating duration.
Operating noises can be heard if the auxiliary heater is switched on.
The 12-volt battery will discharge if the auxiliary heater or ventilation is run several times
over an extended period. Drive the vehicle for an appropriate distance in order to recharge the 12-
volt vehicle battery.
When parked on an incline, the fuel gauge indication (just above the reserve quantityyfPD\
be inaccurate and lead to functional restrictions of the auxiliary heater.
The auxiliary heater may switch on automatically as a supplementary heating measure when
the engine is started at temperatures below +5°C (+41°Fyf7KHVXSSOHPHQWDU\KHDWLQJIXQFWLRQLV
switched off again automatically after a short time.
Programming the auxiliary heater and auxiliary ventilation
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Opening the Auxiliary heater menu
The auxiliary heater is programmed in the Infotainment system.
m/k/a997MK Manual air conditioning system
•Press the button on the Infotainment system.
•Touch the Vehicle and function buttons.
m/k/a997MK Climatronic
•Press the button on the control panel.
•Touch the function button.
Changing the operating mode
•Open the Auxiliary heater menu.
•Touch the Heating or Ventilation function buttons to change the operating mode.
At high outside temperatures, the auxiliary ventilation function supplies fresh air to the vehicle
interior and helps prevent a build-up of heat.
Programming the auxiliary heater
Activation is always for one heating or ventilation period only. The departure time must be activated
for every start.
•Before programming, check that the date and time set in the vehicle are correct ⇒ Vehicle 
settings menu.
•Open the Auxiliary heater menu.
•Press the Adjust button.
•Choose one of the memory locations for a Departure time.
•Touch the Activate function button.
m/k/a995MKManual air conditioning system: the programmed departure time determines
the time at which the auxiliary heater or ventilation should switch off. The point at which the heating
or ventilation process starts is determined depending on the programmed operating period.
m/k/a995MK Climatronic: on the basis of the programmed departure time, the vehicle
automatically calculates the start time for heating or ventilation to the currently set temperature
depending on the outside temperature.
•Touch the Running time function button under Adjust to set the auxiliary heater
running time after the heater is switched on with the immediate heat button or using the
remote control.

m/k/a995MK Vehicles with manual gearbox: change from first to second gear immediately
after setting off. Change to higher gears rapidly.
m/k/a995MK Vehicles with DSG dual clutch gearbox: accelerate slowly and avoid using the
kickdown function.
Gear-change indicator ⇒ Gear-change indicator.
Eco driving profile ⇒ Driving profile selection and 4MOTION Active Control.
Avoid full throttle
Never fully use the maximum speed of the vehicle. Driving at excessive speeds, e.g. above 130
km/h on the motorway, will increase air resistance and thus the amount of force needed to move
the vehicle.
Reduce idling
Drive off immediately with low revs. If you are stopped for a long period, do not allow the engine to
idle but switch it off, e.g. when in a traffic jam or at a railway crossing.
In vehicles with an activated start/stop system, the engine will switch off automatically when the
vehicle is stopping and when the vehicle is stationary ⇒ Start/stop system .
Refuel with moderation
A full fuel tank increases the weight of the vehicle. A fuel tank that is half to three quarters full is
sufficient for urban journeys in particular.
Avoid short journeys
A cold engine has a very high fuel consumption. The optimum operating temperature is reached
only after driving a few miles. The fuel consumption is above average at very low ambient
temperatures, e.g. in winter ⇒ Fig. 116. Plan journeys economically and combine short distances.
Carry out regular maintenance
Regular maintenance is an essential prerequisite for economical driving and increases the service
life of the vehicle.
Observe the correct tyre pressures
An inadequate tyre pressure does not just mean greater wear, but also increases the rolling
resistance of the tyres and thus the fuel consumption. Use optimised rolling resistance tyres.
Adjust the tyre pressure according to the vehicle load. Observe the information on the tyre pressure
sticker ⇒ Useful information about wheels and tyres
Tyre Pressure Loss Indicator or Tyre Pressure Monitoring System ⇒ Tyre monitoring systems.
Use low viscosity engine oil
Fully synthetic engine oils with a low viscosity decrease frictional resistance in the engine and
spread better and more quickly, especially for cold starts.
Do not drive with unnecessary loads in the vehicle
You can reduce fuel consumption by clearing out the luggage compartment before setting off, for
example by removing empty drink crates or unused child seats.
In order to keep the drag coefficient of the vehicle as low as possible, remove attachments and
add-on parts such as ski, bicycle or roof carriers after use.
Save electrical energy
The alternator is driven by the engine and generates power for convenience consumers such as the
air conditioning system, window heating and ventilation. Saving electrical energy is easy, e.g.:
•At high ambient temperatures, ventilate the car before starting a journey and drive a short
distance with open window. Only then switch on the air conditioning system.
•Switch off convenience systems as soon as they have served their purpose.
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road
and traffic conditions.
WARNING

Automatic ignition switch-off
The ignition switches off automatically after a short time if the driver moves away from the vehicle
with the vehicle key when the ignition is switched on. If the dipped beam headlights were switched
on at the time, the side lights will remain switched on for approximately 30 minutes. The side lights
can be switched off manually ⇒ Lights or by locking the vehicle ⇒ Central and manual locking.
Once the vehicle detects that the driver is absent when the engine stop is active, the ignition will
switched off automatically after a certain period of time.
Automatic ignition switch-off in vehicles with a start/stop system
When all the following conditions are fulfilled at the same time, the vehicle ignition will be switched
off automatically when engine stop is active and when the vehicle is stationary:
•The driver removes their seat belt.
•No pedals are depressed.
•The driver door is opened.
If the ignition is deactivated automatically while the dipped beam headlights are switched on ,
the side lights remain switched on for around 30 minutes.
The side lights can be switched off manually or will go off when the vehicle is locked.
Engine restart function
If no valid vehicle key is detected in the vehicle interior once the engine has been switched off, the
engine can be restarted within approximately 5 seconds. A corresponding message appears on the
instrument cluster display.
After this time, the engine cannot be re-started without a valid vehicle key in the vehicle interior.
Before leaving the vehicle, always switch off the ignition manually and observe any
information shown in the instrument cluster display.
Leaving the vehicle stationary for long periods with the ignition switched on can discharge
the 12-volt vehicle battery so that the engine can no longer be started.
The engine cannot, for example, be started with the starter button if the button cell in the
vehicle key is weak or flat. In this case, use the emergency start function ⇒ Emergency start 
function.

parking brake is also activated.
After the engine is switched off, the radiator fan in the engine compartment may run on for
some minutes, even if the ignition is switched off or the vehicle key has been removed. The radiator
fan will switch itself off automatically.
Electronic immobiliser
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The immobiliser helps to prevent the engine from being started and driven with an unauthorised
vehicle key.
There is a chip in the key. This is used to automatically deactivate the immobiliser when a valid
vehicle key is inserted into the ignition lock.
The electronic immobiliser is automatically activated when the vehicle key is removed from the
ignition lock. In vehicles with keyless locking and starting system Keyless Access, the vehicle key
must be outside the vehicle ⇒ Central and manual locking.
