The seat heater and seat ventilation can already be set with the ignition on,
however it only comes on after starting the engine.
88Using the system
When the ignition is switched off, the seat heating and seat ventilation is also
switched off. If the engine is started again within 10 minutes, the driver's seat
heating and seat ventilation is automatically turned on again at the last set-
ting.WARNINGIf you have a subdued pain and/or temperature sensitivity, e.g. through
medication, paralysis or because of chronic illness (e.g. diabetes), we rec-
ommend not to use the seat heating. There may be difficult to heal burns. If
the seat heating is used, we recommend to make regular breaks in your
journey when driving long distances, so that the body can recuperate from
the stress of the journey. Please consult your doctor, who can evaluate
your specific condition.
CAUTION
The following instructions must be observed to avoid damage to the seats.■Do not kneel on the seats or otherwise apply concentrated pressure to them.■
Do not turn on any of the seat heaters if seats are not occupied.
■
Do not switch on the relevant seat heating if the seats have objects attached
to or placed on them, for example a child seat, a bag, etc.
■
When there are additional protective covers or protective covers mounted on
each of the seats, do not turn the seat heating on.
Note
If the on-board voltage decreases, the seat heating and ventilation switches
off automatically » page 216, Automatic load deactivation .

pair the functioning of the Climatronic.
Note
■ During operation of the Climatronic, an increase in engine idle speed can oc-
cur under certain circumstances in order to ensure adequate heating comfort.■
When
is switched on, the air flow to the windows
is switched on. The
air flow to the windows will remain switched on after turning
off.

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.

Audible signals
The interval between the acoustic signals becomes shorter as the clearance is
reduced. A continuous tone sounds from a distance of approx. 30 cm - danger
area. From this moment on do not continue driving!
The acoustic signals can be set in the Infotainment » Owner´s Manual Infotain-
ment , chapter CAR - Vehicle Settings .
Towing a trailer
When towing, or when another accessory is connected to the trailer socket on-
ly the areas

Note■
If with Version 3 vehicles not all fields around the vehicle are active after ac-
tivation the vehicle should be moved forwards or backwards.■
The signal tones for front obstacle recognition are factory-set to be higher
than for rear obstacle recognition.

Note
The distance between the orientations behind the vehicle may vary slightly
depending on the load condition of the vehicle rear and on the road inclination.ABCD153Assist systems
With automatic braking the symbol appears » Fig. 208 in the display.
Advance warning
If the system detects a risk of collision, the symbol
» Fig. 208 appears in the
display and you will hear an acoustic signal.
At the same time, the braking system is prepared for possible emergency brak- ing.
The pre-warning display can occur in the following situations.
▶ If there is a risk of collision with a moving obstacle in a driving speed range of
about 30 km/h to about 210 km/h.
▶ There is a risk of a collision with a stationary moving obstacle in a vehicle
speed range of approximately 30 km/h to about 85 km/h.
With a warning the brake pedal must be pressed or the moving obstacle is to
be avoided!
Acute alert
If the driver does not react to the advance warning, the system briefly applies
the brake automatically via an active brake intervention to draw attention to
the potential danger of a collision again.
Automatic Braking
If the driver fails to respond to the acute warning, the system starts to apply
the brakes automatically with increasing stopping power in several stages.
Brake assist
If the driver brakes inadequate with an impending collision, the system auto-
matically increases braking force.
The braking assistance only occurs as long as the brake pedal is being firmly
pressed down.
Note
■ If an automatic brake intervention is triggered by the system, the pressure in
the brake system increases and the brake pedal cannot be operated with the
normal pedal stroke.■
The automatic braking interventions can be cancelled by pressing the accel-
erator pedal or by steering intervention.
