Vehicle care223Electrical system
High voltage devices and wiring9 Warning
Exposure to high voltage may
cause shock, burns, and even
death. The high voltage
components in the vehicle should
only be serviced by specially
trained technicians.
High voltage components are
identified by labels. Do not
remove, open, take apart, or
modify these components. High
voltage cable or wiring has orange covering. Do not probe, tamper
with, cut, or modify high voltage
cable or wiring.
Electrical system overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
If the current electrical load is too
heavy, the circuit breaker will open
and close, protecting the circuit until
the current load returns to normal or the problem is fixed. This greatly
reduces the chance of circuit
overload and fire caused by electrical
problems.
Fuses and circuit breakers protect the
following parts in the vehicle:
● Headlight wiring
● Windscreen wiper motor
● Power windows and other power accessories
Headlight wiring An electrical overload may cause the
lights to go on and off or in some
cases to remain off. In this case, have
the headlight wiring checked
immediately by a workshop.
Windscreen wipers
If the wiper motor overheats due to
blockage from heavy snow or ice, the windscreen wipers will stop until themotor has cooled down and the wiper
control has been turned off. Afterremoval of the blockage, the wiper
motor will restart when moving the
wiper control to the desired operating
position.
Although the circuit is protected from
electrical overload, mechanical
overload due to heavy snow or ice
may cause wiper linkage damage.
Always clear ice and heavy snow
from the windscreen before using the windscreen wipers. If the overload is
caused by an electrical problem and
not snow or ice, it must be serviced.
Fuses
Data on the replacement fuse must match the data on the defective fuse.
There are two fuse boxes in the
vehicle:
● at the front left side of the engine
compartment
● at the left side of the instrument panel
Before replacing a fuse, turn off the
respective switch and the vehicle.
Vehicle care243short edge of the cap. Release the
cap by carefully moving the
screwdriver sidewards.
The towing eye is stowed with the vehicle tools 3 231.
Screw in the towing eye anticlockwise
as far as it will go until it stops in a
horizontal position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
The towing eye must only be used for
towing and not for recovering the
vehicle.
Switch on the vehicle to release
steering wheel lock and to permit
operation of brake lights, horn and
windscreen wiper.Caution
Deactivate the driver assistance
systems like active emergency
braking 3 170, otherwise the
vehicle may automatically brake during towing.
Shift the selector lever of the electric
drive unit into N.
Release the electric parking brake.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the vehicle is not running, considerably more force is needed to
brake and steer.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation and close the
windows.
Seek the assistance of a workshop.
After towing, unscrew the towing eye.
Insert cap at the bottom and close.
Towing another vehicle The vehicle is neither designed nor
intended to tow a trailer or another
vehicle.
244Vehicle careAppearance careExterior care
Locks The locks are lubricated at the factoryusing a high quality lock cylinder
grease. Use de-icing agent only when
absolutely necessary, as this has a
degreasing effect and impairs lock function. After using a de-icing agent, have the locks regreased by a
workshop.
Washing The paintwork of your vehicle is
exposed to environmental influences. Wash and wax your vehicle regularly.
When using automatic vehicle
washes, select a programme that
includes waxing.
Do not apply waxes or polishes to uncoated plastic, vinyl, rubber,
decals, simulated wood, or flat paint
as damage can occur.Bird 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 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.
Vehicle care245Paintwork 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 damage Rectify minor paintwork damage witha touch-up pen before rust forms.
Have more extensive damage or rust areas repaired by a workshop.
Underbody
Some areas of the vehicle underbody
have a PVC undercoating while other
critical areas have a durable
protective wax coating.
After the underbody is washed, check the underbody and have it waxed if
necessary.
Bitumen / rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.Before and after winter, wash the
underbody and have the protective
wax coating checked.
Interior care
Interior and upholstery
Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean the leather upholstery with
clear water and a soft cloth. In case of heavy soiling, use leather care.
The instrument cluster and the
displays should only be cleaned using
a soft damp cloth. If necessary use a
weak soap solution.
Do not spray cleaners directly on any switches or controls.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
Clothing fabrics may not be
colourfast. This could cause visible
discolourations, especially on light-
