Manual air recirculation 4
Touch 4 to activate the air
recirculation mode.
Touch 4 again to deactivate
recirculation mode.
If selected, the touch screen button
will illuminate to indicate that air is
being recirculated. This helps to
quickly cool the air inside the vehicle or prevent outside air and odours
from entering.
Touching 4 deactivates air
recirculation. Press AUTO to return to
automatic operation; recirculation
runs automatically as needed.
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.
Remote heating and cooling
Operated by pressing O on the
electronic key.
The climate control system will default
to an appropriate heating or cooling
mode and the rear window heating
will turn on in the event of cold outside temperatures.
Remote start 3 17.
146Climate controlMaintenanceAir intake
The air intake in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Pollen filter The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Additionally, an active carbon filter
reduces odours.
Air conditioning regular
operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when the
outside temperature is too low.
Service For optimal cooling performance, it is recommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
● functionality and pressure test
● heating functionality
● leakage check
● check of drive belts
● cleaning of condenser and evaporator drainage
● performance check
204Driving and operating● Solid green – No horn chirps:Charging is complete.
● Solid yellow – No horn chirp: Vehicle is plugged in. It is normal
for the charging status indicator
to turn yellow for a few seconds
after plugging in a compatible
charge cord. The solid yellow
may remain illuminated
depending on the vehicle.
This may also indicate that the
charging system has detected a
fault and will not charge the high
voltage battery.
● No light signal (upon plug‐in) – No horn chirps: Charge cord
connection should be checked.
● No light signal (after indication of
green or yellow charging status
indicator) – No horn chirps:
Charge cord connection should
be checked. If connection is
correct, this may be due to a
power failure and charging will
begin later. This may also occur
if the vehicle has detected a high
voltage charging system fault.● No light signal – Three horn chirps: Charge port door is open.
● No light signal – Horn chirps repeatedly: The power supply
was interrupted before the
charging process could be
completed. Repeated chirps will stop if power is restored within
90 seconds.
Vehicle personalisation 3 91.
The system may be thermally
conditioning the high voltage battery
during any of the states mentioned
above, requiring electric energy to be
transferred to the vehicle.
If the vehicle is plugged in and vehicle
power is on, the charging status
indicator will flash or illuminate solid
green, depending on the charge level. This also happens during Engine
Assisted Heating if the vehicle is
plugged in.
If the vehicle is plugged in and the
charging status indicator is off, a
charging fault has been detected.Charge cord9 Danger
There is a risk of electric shock
that may cause personal injury or
death.
Do not use the charge cord if any part of the charge cord is
damaged.
Do not open or remove the charge cord cover.
Service by qualified personnel
only. Connect the charge cord to a
properly grounded outlet with
cords that are not damaged.
A portable charge cord used to
charge the vehicle high voltage
battery is stored under the rear floor
storage cover in the load
compartment 3 193.

Vehicle care241Bird droppings, dead insects, resin,
pollen and the like should be cleaned
off immediately, as they contain
aggressive constituents which can cause paint damage.
If using a vehicle wash, comply with
the vehicle wash manufacturer's instructions. The windscreen wiperand 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.
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 four to nine.
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 windscreen wiper
blades
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.
