LED headlights 3 134.
Tunnel detection
When a tunnel is entered headlights
are switched on immediately.
High beam assist
The camera in the windscreen
detects the lights of oncoming or
preceding vehicles. Once activated,
high beam assist remains active and switches high beam on and off
automatically. The latest setting of the high beam assist will remain after theignition is switched on again.
It switches automatically to low beam
when:
● Driving in urban areas.
● It is foggy or snowy.
● Fog lights are switched on.If there are no restrictions detected, the system switches back to high
beam.
This feature allows the high beam to
function as main driving light at night.
Each LED on right or left side is
triggered or faded out particularly according to the traffic situation. This
gives the best light distribution
without dazzling other road users.
High beam is switched on
automatically at a speed above
50 km/h. High beam is switched off at a speed below 35 km/h, but highbeam assist remains active.

142Climate controlPress 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.

Air recirculation system nPress n to activate air recirculation
mode, LED is indicated.
Press n 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.
Maximum cooling
Briefly open the windows so that hot
air can disperse quickly.
● Switch on cooling A/C.
● Press n for air recirculation
system on.
