Exterior mirrors
80WARNING■ Convex (curved outward) or aspheric exterior mirrors increase the field of
vision. They do, however, make objects appear smaller in the mirror. These
mirrors are therefore only of limited use for estimating distances to the fol-
lowing vehicles.■
Whenever possible use the interior mirror for estimating the distances to
the following vehicles.
WARNINGThe mirrors with automatic dimming contain an electrolyte liquid which can
escape if mirror glass is broken.■
The leaking electrolytic fluid can irritate the skin, eyes and breath appara-
tus.
■
If your eyes or skin come into contact with the electrolytic fluid, immedi-
ately wash the affected area for a few minutes long with a lot of water. If
necessary get medical assistance.

Mirror blackout
Mirror with automatic dimming
After starting the engine, the mirror darkens » Fig. 70 -
automatically.
The mirror dimming is controlled by the light incident on the sensors on the
front and back of the mirror.
When the interior lights are switched on or the reverse gear is engaged, the
mirror moves back into the basic position (not dimmed).
Do not attach external devices (e.g. navigation systems) on to the windscreen or in the vicinity of the interior mirror »
.
WARNING■
The illuminated display of an external navigation device can lead to op-
erational faults to the automatic dimming interior mirror – risk of accident.■
The automatic dimming mirror only functions smoothly if the light falling
on the sensors is not impaired, e.g. by the rear sun roller blind.

Climatronic - automatic operation
Read and observe
and on page 119 first.
The automatic mode is used in order to maintain a constant temperature and
to demist the windows in the interior of the car.
Automatic mode can be switched off by pressing any of the air distribution
buttons or by increasing/decreasing the blower speed. The temperature regu-
lation is continued.
Operating modes
Automatic mode works in three modes - moderate, medium, and intensive.
Setting the individual operating modes » Owner´s Manual Infotainment , chap-
ter Setting the heating and the cooling system .
After the automatic mode is switched on, Climatronic works in the last selec-
ted mode.
The currently selected mode is displayed in the Infotainment display.
121Heating and ventilation
NoteClimatronic is set to the medium setting at the factory.
Air distribution controlRead and observe
and on page 119 first.
The recirculation mode prevents contaminated outside air getting into the In-
terior of the vehicle.
In recirculated air mode air is sucked out of the interior of the vehicle and then
fed back into the interior.
Switching on and off
›
Press the button.
When the recirculation mode is activated, the warning light below the button
lights up.
Heating and manual air conditioning system
If the air distribution control is set to position when the recirculation modes
is switched on, the recirculated-air mode is switched off. Recirculated air mode
can be switched on again from this position by repeatedly pressing the symbol
key .
When the is switched on and the temperature regulator is turned to the
left, the recirculated-air mode is switched on.
Climatronic
Climatronic may have an air quality sensor for the detection of the pollutant
concentration in the sucked-in air.
If a considerable increase in concentration of pollutants is recognised by the
air quality sensor, recirculated air mode will temporarily be switched on.
When the pollutant concentration decreases to the normal level, the recircula-
ted air mode is automatically switched off.
This automatic on/off switching of the recirculated-air mode can be activated
or deactivated in the Infotainment » Owner´s Manual Infotainment , chap-
ter Setting the heating and the cooling system .
If the button is pressed when the recirculation modes is switched on, the
recirculated-air mode is switched off.
Depending on the moisture conditions in the vehicle interior the air recircula- tion may also shut-down automatically.
WARNINGThe recirculation system cannot be switched on for a longer period of time,
because there is no supply of fresh air from the outside. “Stale air” may re-
sult 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.
Switch off recirculated air mode as soon as the windows start to mist up.
CAUTION
We recommend not smoking in the vehicle when the recirculating air operation
is switched on. The smoke sucked from inside the vehicle is deposited on the
evaporator of the air conditioner. This produces a permanent odour when the
air conditioning system is operating which can only be eliminated through con-
siderable effort and expense (replacement of compressor).
Note
The automatic activation/deactivation of the air recirculation with Climatronic
only works if the outside temperature is higher than approx. 2 °C.

122Using the system
■Oncoming vehicles can generate water waves which can exceed the permis-
sible water level for your vehicle.■
Potholes, mud or rocks can be hidden under the water, making it difficult or
impossible to drive through the body of water.
■
Do not drive through salt water, as the salt can cause corrosion. An vehicle
coming into contact with salt water is to be thoroughly rinsed with fresh wa-
ter.

143WARNINGThe following general information regarding the use of assistance systems
must be observed.■
The assistance systems only serve to support the driver and do not re-
lieve the driver of the responsibility for driving the vehicle.
■
The increased safety provision, as well as the increased occupant protec-
tion provided by the assistance systems must not tempt you to take risks -
risk of accident!
■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions.
■
The assistance systems have physical and system-related limitations. For
this reason, the driver may experience some undesired or delayed system
responses in certain situations. You should therefore always be alert and
ready to intervene!
■
Only enable, disable or set the assistance systems when you have the car
fully under control, in every traffic situation - risk of accident!

Radar sensorFig. 174
Mounting location of the radar
sensor
Read and observe on page 142 first.
The radar sensor (hereinafter referred to only sensor) uses electromagnetic
waves to capture the traffic situation ahead of the vehicle. The radar is located
under a cover » Fig. 174.
The sensor is part of the ACC » page 163 and Front Assist » page 168systems.
The sensor function may be impaired in the event of one of the following sit-
uations arising. ▶ The sensor cover is soiled by mud, snow and the like.
▶ The area in front and around the sensor cover is obscured by labels, auxiliary
lights and similar.
▶ When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
▶ In exceptional cases, the sensor may be covered up in the area under the
cover, e.g. due to snow.
If the sensor cover of the sensor is dirty or covered, a message to that effect
from the ACC » page 168 or Front Assist » page 171 system appears in the
instrument cluster display.
WARNING■ If you suspect that the sensor has been damaged, deactivate the ACC
» page 163 und Front Assist » page 168 system. Have the sensor checked
by a specialist garage.■
The sensor can become misaligned by collisions or by damage to the front
of the vehicle, the wheel arch or the underside of the vehicle. This can lead
to impaired function of the sensor - risk of accident! Have the sensor
checked by a specialist garage.
■
The area in front and around the sensor cover should not be obscured by
labels, auxiliary lights and similar. This can lead to impaired function of the
sensor - risk of accident!

the vicinity of the vehicle.
WARNING■ The general information relating to the use of assistance systems must
be observed » page 142, in section Introduction .■
Moving persons or objects may not be recognized by the system sensors.
■
Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the system signals. For this reason, such people or
objects may not be recognised by the system sensors.
WARNING (Continued)■ External noise sources may affect the signals of the system sensors. Un-
der adverse conditions, this may cause objects or people not to be recog-
nised by the system.■
Before reversing, you should make sure that there are no small obstacles,
such as rocks, thin posts, trailer draw bars etc. in front or behind your vehi-
cle. Such obstacles may not be recognised by the system sensors.
CAUTION
■ Keep the system sensors » Fig. 177 on page 147 clean, snow-and ice-free
and do not cover with any objects of any kind, otherwise the system function-
ing may be impaired.■
Under adverse weather conditions (heavy rain, water vapour, very low or
high temperatures, etc.), the system function may be limited - “incorrect recog-
nition of obstacle”.
