Air recirculation system u
Press u to activate air recirculation
mode. The LED in the button
illuminates to indicate activation.
Press u again to deactivate air
recirculation mode.
9 Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen may mist
up from outside when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate l.
Demisting and defrosting
● Press l: the air distribution is
directed towards the windscreen.
● Set temperature controller n to
warmest level.
● Set fan speed x to highest level.
● Switch on heated rear window e.
● Open side air vents as required and direct them towards the doorwindows.

Cooling A/C
Press A/C to switch on cooling. The
LED in the button illuminates to
indicate activation. Cooling is only
functional when the engine is running
and fan is switched on.
Press A/C again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
the freezing point. Therefore,
condensation may form and drip from
under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons.
Activated cooling may inhibit
Autostops. Stop-start system 3 147.

Driving and operating191will start a parking manoeuvre. Take
care regarding the availability of the
suggested parking slot.
Surface irregularities, e.g. on
construction zones, are not detected
by the system. The driver accepts
responsibility.
Side blind spot alert The side blind spot alert system
detects and reports objects on either
side of the vehicle, within a specified
blind spot zone. The system displays
a visual alert in each exterior mirror,
when detecting objects that may not
be visible in the interior and exterior
mirrors.
Side blind spot alert uses some of the advanced parking assist sensors
which are located in the front and rear
bumper on both sides of the vehicle.9 Warning
Side blind spot alert does not
replace driver vision.
The system does not detect:
● vehicles outside the side blind zones which may be rapidly
approaching
● pedestrians, cyclists or animals
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
Activation
Colour Info Display: press Í. Select
Driving functions on the Info Display
and then Blind spot sensors . Activate
the function.
B illuminates continously green in the
instrument cluster to confirm the
function.
Functionality
When the system detects a vehicle in the side blind zone while driving
forwards, an LED will illuminate in the
relevant exterior mirror.
The LED comes on immediately when being passed.
The LED comes on after a delay when
passing another vehicle slowly.

192Driving and operatingOperation conditions
The following conditions must be
fulfilled for proper operation:
● all vehicles are moving in the same direction and in adjacent
lanes
● the speed of your vehicle is between 7 and 87 mph
● passing a vehicle with a speed difference of less than 6 mph
● another vehicle is passing with a speed difference of less than
15 mph
● the traffic flow is normal
● driving on a straight or slightly curved road
● the vehicle is not pulling a trailer
● the sensors are not covered by mud, ice or snow
● the warning zones in the door mirrors or the detection zones on
front and rear bumper ar not
covered with adhesive labels or
other objectsNo alert will be given in the following
situations:
● in the presence of non-moving objects, e.g. parked vehicles,
barriers, street lamps, road signs
● with vehicles moving in the opposite direction
● driving on a winding road or a sharp corner
● when passing or being passed by
a very long vehicle, e.g. lorry,
coach, which is at the same time
detected at the rear in the blind
spot angle and present in the
driver's forward field of vision
● in very heavy traffic, vehicles detected in front and behind are
confused with a lorry or a
stationary object
● when passing too quickly
Deactivation The system is deactivated in the
vehicle personalisation 3 115. B
extinguishes in the instrument cluster.
Additionally, an acoustic signal
sounds.The state of the system is stored
when switching off the ignition.
The system is automatically
deactivated when towing an
electrically connected trailer.
Due to adverse weather conditions
such as heavy rain, false detections
may occur.
Fault
In the event of a fault, B flashes for a
few moments in the instrument panel,
accompanied by C and a display
message. Have the cause of the fault remedied by a workshop.
Passenger side camera
The passenger side camera monitors the side of the vehicle.
Page 195 of 279

Driving and operating193
The camera is mounted at the bottomof the exterior mirror on the
passenger side.
The passenger side view is displayed
in the rear view display 3 113.
The area displayed by the camera is limited. The distance of the image that
appears on the display differs from
the actual distance.
Switching on
The camera is switched on when the vehicle is running in forward gear and the passenger side view is selectedfrom the rear view display.
Guidelines
The line represents a distance of
about 4 m beyond the edge of
vehicle's rear bumper.
Switching off The camera is deactivated when
another view type is selected.
Panoramic view system
This system allows views of the
vehicle's surroundings to be
displayed as a nearly 180° picture in
the Info display, like a bird's eye view.
The system uses:
● rear camera, installed in the tailgate
● ultrasonic parking sensors in the rear bumper
The screen in the Info display is
divided into two parts. On the right
there is a view from above the vehicle,
and on the left there is the view from
the rear displayed. The parking
sensors complete the information on
the view from above the vehicle.
Change the volume of the acoustic
signals by pressing C in the right
lower zone of the display.
