Climate control147Additionally, 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
Driving and operating205begin later. This may also occurif 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 supplywas interrupted before the
charging process could be
completed. Repeated chirps will stop if power is restored within
90 seconds.
Vehicle personalisation 3 92.
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.
Important information about
portable electric vehicle charging
● Charging an electric vehicle can stress a building's electrical
system more than a typical
household appliance.
● Before you plug in to any electrical outlet, have a qualifiedelectrician inspect and verify the
electrical system (electrical
outlet, wiring, junctions and
protection devices) for heavy-
duty service at a 10 ampere
continuous load.
● Electrical outlets may wear out with normal usage or be
damaged over time, making them
unsuitable for electric vehicle
charging.
● Check the electrical outlet/plug while charging and discontinueuse if the electrical outlet/plug is
hot, then have the electrical
outlet serviced by a qualified
electrician.

Vehicle care241Caution
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.Remove dirt residues from smearing wiper blades by using 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.
Wheels and tyres
Do not use high-pressure jet
cleaners.
Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.
Paintwork damageRectify minor paintwork damage with
a touch-up pen before rust forms. Have more extensive damage or rust
areas repaired by a workshop.
