detaching of the windscreen wiper
blades if they are frozen to the
windscreen. Additionally, an
accumulation of snow caused by the
operation of the windscreen wipers is
prevented.
Heating is operated by pressing 9.
LED in button illuminates.
Heating works with the engine
running and is switched off
automatically depending on the
ambient temperature.
Pressing 9 again switches off the
heating operation. LED in button is
extinguished.

Automatic headlight activation
During poor lighting conditions the
headlights are switched on.
Additionally, headlights are switched
on if the windscreen wipers have
been activated for several wipes.
High beam
To activate the high beam, pull the
lever beyond the resistance point.
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 the ignition is switched on again.
This feature automatically activates
the high beam at night when vehicle
is faster than 25 km/h.
It switches automatically back to low
beam when:
● A sensor detects the lights of oncoming or preceding vehicles.
● Driving in urban areas.
● The vehicle is slower than 15 km/h.
● It is foggy or snowy.
● Front or rear fog lights are switched on.
If there are no restrictions detected,
the system switches back to high
beam.

deactivates certain functions, such as
the air conditioning, the heated rear
window, heated steering wheel, etc.
The deactivated functions are
reactivated automatically as soon as
conditions permit.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must be increased. This will be achieved by
an idle boost which may be audible.
A message appears in the Driver

254Vehicle careIf using a vehicle wash, comply with
the vehicle wash manufacturer's
instructions. The windscreen wiper and rear window wiper must be
switched off. Remove antenna and
external accessories such as roof
racks etc.
If you wash your vehicle by hand,
make sure that the insides of the
wheel housings are also thoroughly
rinsed out.
Wax painted parts of the vehicle
regularly.
Clean edges and folds on opened
doors and the bonnet as well as the
areas they cover.
Clean bright metal mouldings with a
cleaning solution approved for
aluminium to avoid damages.Caution
Always use a cleaning agent with
a pH value of 4 to 9.
Do not use cleaning agents on hot surfaces.
Do not clean the engine compartmentwith a steam-jet or high-pressure jet
cleaner.
Thoroughly rinse and leather-off the vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Have the door hinges of all doors
greased by a workshop.
Do not use hard objects to remove
spots of tar. Use tar removal spray on
painted surfaces.
Exterior lights
Headlight and other light covers are
made of plastic. Do not use any
abrasive or caustic agents, do not use an ice scraper, and do not clean them
dry.
Polishing and waxing
Wax the vehicle regularly at the latest when water no longer beads.
Otherwise, the paintwork will dry out.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.
Plastic body parts must not be treated
with wax or polishing agents.
Windows and wiper blades
Switch off wipers before handling in their areas.
Use a soft lint-free cloth or chamois
leather together with window cleaner
and insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Clean smearing wiper blades with a
soft cloth and window cleaner. Also
make sure to remove any residues
such as wax, insect residues and
similar from the window.
Ice residues, pollution and continuous wiping on dry windows will damage or
even destroy the wiper blades.
