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 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.

Swallowing batteries with a diameter of 20 mm, or other button cells, can result in severe
or even fatal injuries within a very short period of time.
•Always keep the remote control key, key ring with batteries, spare batteries, round
cells and other batteries that are larger than 20 mm out of the reach of children.
•Call for medical help immediately you suspect that someone has swallowed a battery.
DANGER
•The remote control contains electronic components. Protect the remote control from
moisture, excessive vibration and direct sunlight.
•Unsuitable batteries can damage the remote control. Replace discharged batteries only
with new batteries of the same voltage rating, size and specification.
•Ensure that the battery is fitted the right way round.
NOTICE
Driving under the influence of alcohol, drugs, medication or narcotics can cause serious
accidents and fatal injuries.
•Alcohol, drugs, medication and narcotics can severely impair perception, reaction
times and driving safety. This could cause you to lose control of the vehicle.
WARNING
Rapid acceleration can cause loss of traction and skidding, particularly on slippery roads.
This can cause you to lose control of the vehicle, which can lead to accidents and serious
injuries.
•Always adjust your driving style in accordance with the flow of traffic.
•The kickdown function or fast acceleration should only be used if the visibility,
weather, road and traffic conditions permit.
WARNING
m/k/a995MK Vehicles with DSG dual clutch gearbox: the selector lever must be in the
Tiptronic position ⇒ Changing gear using Tiptronic.
No recommended gear is indicated if the most suitable gear is already selected. The currently
selected gear is displayed.
Information on cleaning the particulate filter
The engine management system recognises when the particulate filter is becoming saturated and
supports regeneration of the particulate filter by recommending the most suitable gear when driving.
Compared with normal driving, this may mean driving with an increased engine speed ⇒ Particulate
filter.
Driving in the correct gear can help to reduce fuel consumption.
Gear-change indicator display goes out when the clutch is depressed in vehicles with a
manual gearbox or when Tiptronic position is deselected in vehicles with a DSG dual clutch
gearbox.
Driving economically
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The fuel consumption, pollution and
wear of the engine, brakes and tyres
are reduced by an appropriate driving
style. A few tips are provided below
which will help you protect the
environment and also save money.
Fig. 116 Fuel consumption in litres per 100 km at two different outside temperatures.
Think ahead when driving
The fuel consumption will increase if you do not adopt a steady driving style. Keeping a close eye
on the traffic can help to avoid frequent acceleration and braking. Keeping a sufficient distance from
the vehicle in front will help you anticipate the driving situation.
Use the cruise control system where possible ⇒ Cruise control system (CCSyf.
With a gear engaged, allow the vehicle to come to a halt by itself to make use of the engine braking
effect, e.g. when approaching traffic lights.
Using freewheeling
m/k/a995MKVehicles with a DSG dual clutch gearbox: When the selector lever is in

With the engine-off coasting function, the engine is not just disengaged, but is also switched off.
Driving with DSG dual clutch gearbox ⇒ Driving with DSG dual clutch gearbox.
Change gears in an energy-saving way
Shifting up early at an engine speed of 2,000 rpm will save energy. Do not drive gears to the limit
and avoid high revs.
The gear-change indicator is only designed to assist the driver and cannot replace the
driver's own judgement.
•The driver has full responsibility for selecting the correct gear in all situations (e.g.
when overtaking, driving up and down hills ⇒ Trailer towingand when towing a traileryf .
CAUTION
®
®®
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.
