The cooling system only operates if the following conditions are met. The cooling system is switched on » page 110, Control elements .
The engine is running.
The outside temperature above approx. +2 °C.
The blower switch is switched on (positions 1-6).
If the desired interior temperature can also be achieved without activating the cooling system, fresh air mode should be selected.
The cooling system is switched off at a high coolant temperature in order to pro-
vide cooling at a high load of the engine.
CAUTION
■ Under certain circumstances, air at a temperature of about 5 °C can flow out of
the vents when the cooling system is switched on.■
Lengthy and uneven distribution of the air flow out of the vents (especially
around the feet) and large differences in temperature, for example, when getting
out of the vehicle, can cause susceptible individuals to catch a cold.
Note
We recommend that you have the air conditioning system cleaned by a specialist
garage once every year.Control elementsFig. 109

The Climatronic in automatic mode ensures the best-possible setting of the tem-
perature of the outflowing air, the blower stage and air distribution.
The system also takes sunlight into account, which eliminates the need to alterthe settings manually.
The cooling system only operates if the following conditions are met. The cooling system is switched on » page 112, Control elements .
The engine is running.
The outside temperature above approx. +2 °C.
The cooling system is switched off at a high coolant temperature in order to pro-

ABCD123112Using the system
CAUTIONLengthy and uneven distribution of the air flow out of the vents (especially
around the feet) and large differences in temperature, for example, when getting
out of the vehicle, can cause susceptible individuals to catch a cold.
Automatic recirculation mode
First read and observe the introductory information given on page 112.
Recirculated air mode prevents polluted air outside the vehicle from getting into
the vehicle, for example when driving through a tunnel or when standing in a
traffic jam.
If a considerable increase in concentration of pollutants is recognised by the air
quality sensor, recirculated air mode will temporarily be switched off.
If the concentration of pollutants decreases to the normal level, the air distribu-
tion control is automatically switched off so that fresh air can be guided into the
vehicle interior.
In recirculated air mode air is sucked out of the interior of the vehicle and then
fed back into the interior. When the automatic air distribution control is switched on, an air quality sensor measures the concentration of pollutants in the drawn in
air.
If the air quality sensor does not switch on automatic recirculated air mode when
there is an unpleasant smell, you can switch in on manually.
Switching on/off
›

WARNINGNever leave recirculated air mode switched on over a longer period of time, as
“stale air” can cause driver and passenger fatigue, reduce attention levels and
also cause the windows to mist up. The risk of having an accident increases.
Switch off recirculated air mode as soon as the windows start to mist up.
Note
■ If the windscreen mists up, press the symbol button . Press the symbol
button when the windscreen is demisted.■
The automatic air distribution control operates only if the outside temperature
is higher than approx. 2 °C.
Controlling blower
First read and observe the introductory information given on page 112.
The blower stage can be manually adapted to suit your particular needs.
›
Turn the control dial
C
» Fig. 110 on page 112 to the left or right to increase or
decrease the temperature.
If the blower speed is reduced to a minimum, Climatronic is switched off.
The set blower speed is displayed in the control dial
C
when the respective num-
ber of warning lights illuminate.
WARNING■ “Stale air” may result in fatigue in the driver and occupants, reduce attention
levels and also cause the windows to mist up. The risk of having an accident
increases.■
Do not switch off the Climatronic system for longer than necessary.
■
Switch on the Climatronic system as soon as the windows mist up.
114Using the system
If an engine is only idling it takes much longer for it to reach its normal operating
temperature. Wear-and-tear and pollutant emissions, though, are particularly
high in the warming-up phase. Therefore, start driving as soon as the engine has
started. though high engine speeds should be avoided.
Avoiding short distances
Fig. 125
Principle sketch: Fuel consump-
tion in l/100 km at different tem-
peratures
First read and observe the introductory information and safety warn-
ings on page 131.
Short distances result in an above-average high fuel consumption. We therefore recommend avoiding distances of less than 4 km if the engine is cold.
A cold engine consumes the most fuel immediately after the start. Fuel consump-tion drops to 10 litres/100 km after just 1 kilometre. The consumption stabilises
once the engine and catalytic converter have reached their operating tempera-
ture.
An important factor in this connection is also the ambient temperature. The im-
age » Fig. 125 shows the different levels of fuel consumption after driving a cer-
tain distance at a temperature of +20 °C and at a temperature of -10 °C.
The vehicle has a higher fuel consumption in winter than in summer.
Convenience consumers
First read and observe the introductory information and safety warn-ings
on page 131.
The convenience consumers have a share in fuel consumption.
We recommend you keep these consumers on only for as long as necessary. The convenience consumers include:
› The air conditioning system;
› Rear window heater;
› Windscreen heater;
› Heating of the external mirror;
› Rear fog light;
› Fog lights;
› Heated front seats;
› Auxiliary heating (parking heating).
Information about convenience consumers and the amount of fuel con- sumed » operating instructions for Infotainment , chapter Vehicle settings (CAR
button) .
Up to three convenience consumers are displayed in the Infotainment display-
the top 3 in terms of energy consumption 1)
.
Checking tyre inflation pressure
First read and observe the introductory information and safety warn-ings
on page 131.
Tyres which are correctly inflated save fuel.
Always ensure the tyre inflation pressure is correct. If the inflation pressure is too
low, the tyres must overcome a higher rolling resistance. This will not only in-
crease fuel consumption but also tyre wear and the driving behaviour will worsen.
Always check the tyre inflation pressure when the tyres are cold.
1)
The exterior mirror heater will only be shown in the infotainment display when outside temperatures
are below about 20 ° C.
133Starting-off and Driving
Note■The Eco driving mode is not available when towing a trailer. When the vehicle is
connected electrically to a trailer and is in the Eco driving mode, the Normal driv-
ing mode is configured automatically.■
The maximum vehicle acceleration (kickdown function) is possible also in driving
mode Eco.

ProActive passenger protection
Introduction
This chapter contains information on the following subjects:
Function
163WARNINGAdjust the speed and driving style to the current visibility, weather, road and
traffic conditions. The increased safety by ProActive passenger protection must not tempt you to take greater risks than otherwise – risk of accident!
Note
■ If the front passenger front airbag is deactivated » page 191 the belt tension-
ing function for the front passenger seat is switched off.■
The system component service life is monitored electronically. Further informa-
tion » page 19 , Security Systems .
Function
First read and observe the introductory information and safety warn-ings
on page 163.
ProActive passenger protection (From here on referred to only as system) increa-
ses passenger protection in the front seats in situations that could lead to vehicle
impact or overturning.
The system is ready to intervene automatically in the following conditions. The ignition is switched on.
The vehicle moves at a speed of more than 30 km/h.
In critical driving situations (e.g. during emergency braking or a sudden change in
direction), the following steps can be taken separately or combined in order to re-
duce the risk of serious injury.
› The front passenger's and driver's seatbelts, if worn, are automatically
ten-
sioned closely over the body.
› The windows in the side doors (if open) are automatically closed up to a gap of
about 5 cm from the edge.
› The sliding/tilting roof is closed.
Once the critical driving situation has passed, the tension on the seatbelts will be
released again.
The system operates at two levels of protection.
The first level of protection
The system already intervenes in situations that may occur during dynamic driv-
ing. As a result, this primarily helps to keep the driver and the passenger in the
correct seated position.
The first level of protection can be deactivated by one of the following measures. › Deactivation of the system in Infotainment
» Operating instructions for Info-
tainment , chapter Vehicle settings (CAR button) .
› Deactivation of TCS
» page 138.
› Selecting the driving mode Sport
» page 161.
The second level of protection
The system intervenes only if the situation is evaluated as critical, such as in pan-
ic braking at high speeds.
This level of protection cannot be deactivated.

Information messages
166WARNING■ Lane Assist only operates as a support- it does absolve the driver of the re-
sponsibility to maintain full control over the vehicle's steering.■
Lane Assist only makes the driver away that the vehicle is approaching the
line between two lanes by means of a steering intervention. The driver retains
responsibility at all times for keeping the vehicle within the lane.
■
Lane Assist can help you keep the vehicle within the lane. However, it does
not steer the vehicle for you. The driver retains full responsibility for steering at all times.
■
The camera need not be able to detect all lane lines. A steering intervention
can only be made when the vehicle approaches a detected line between lanes.
■
Some objects on the road may be incorrectly detected as lines. As a result,
an incorrect steering intervention may take place.
■
The function of adaptive lane guidance Assist system may be restricted
when driving e.g. over rutted roads, on a slope, or if there are lateral winds.
■
Do not use the assist system in poor weather, e.g. black ice, fog, heavy rain –
risk of accident!
WARNINGThe detection capability of the camera may be limited by various external in-
fluences. In such cases, the assistant may not detect the line between two
lanes at all or not properly. The detection capability of the camera may be re- stricted in the following situations, for example.■
When visibility conditions are poor, e.g. fog, heavy rain, thick snowfall.
■
When driving around “sharp” bends.
WARNING (Continued)■ The camera is blinded by the sun.■The camera is blinded by the oncoming traffic.■
The viewing range of the camera is impeded by a vehicle traveling ahead.
■
The camera viewing range is obstructed by an obstacle.
CAUTION
Do not attach any stickers or similar objects to the windscreen to avoid impairing
the functions of the Assist system.
Note
■ The system is designed for driving on motorways and roads with adequate lon-
gitudinal markings.■
The system can detect both continuous and broken lines.

First read and observe the introductory information and safety warn-
ings on page 164.
Lane Assist (From here on referred to only as the system), helps to keep the vehi-
cle within the lane.
The system detects the boundary lines of a lane using the camera » Fig. 147.
When the vehicle approaches a detected line between lanes, the system makes a
light movement of the steering wheel in the opposite direction to the boundary
line. This corrective steering intervention can be overridden at any time.
