● instrument panel
Before replacing a fuse, turn off the
respective switch and the ignition.
A blown fuse can be recognised by its melted wire.Caution
Do not replace the fuse until the
cause of the fault has been
remedied.
Some functions are protected by
several fuses.
Fuses may also be inserted without
existence of a function.

Vehicle care2354.Screw the compressor air hose to
the connection on the sealant
bottle.
5. Fit the sealant bottle into the bracket on the compressor.
Set the compressor near the tyre
in such a way that the sealant
bottle is upright.
6. Unscrew valve cap from defective
tyre.
7. Screw the filler hose to the tyre valve.
8. The switch on the compressor must be set to J.
9. Connect the compressor plug to
the power outlet or cigarette
lighter socket.
The tyre repair kit may only be
plugged in to the front 12 V power
outlet, in order to work properly.
To avoid discharging the battery,
we recommend running the
engine.
10. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.
11. The compressor pressure gauge briefly indicates up to
600 kPa (6 bar) whilst the sealant
bottle is emptying (approx. 30 s).
Then the pressure starts to drop.
12. All of the sealant is pumped into the tyre. Then the tyre is being
inflated.
13. The prescribed tyre pressure should be obtained within ten
minutes.
Tyre pressure 3 263.
When the correct pressure is
obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within ten minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for ten minutes. If the prescribed tyre
pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.

Vehicle care2433. Connect the black lead to thenegative terminal of the booster
battery.
4. Connect the other end of the black
lead to a vehicle grounding point
of your vehicle in the engine
compartment.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump.
2. After five minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of one
minute.
3. Allow both engines to idle for approx. three minutes with the
leads connected.
4. Switch on electrical consumers e.g. headlights, heated rear
window of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle
Wrap a cloth around the tip of a flat
screwdriver, for example, to prevent
paint damage. Insert the screwdriverin the slot at the lower part of the cap.
Release the cap carefully.
The towing eye is stowed with the vehicle tools 3 228.
Screw in the towing eye 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 ignition to release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.

246Vehicle 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.
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.

248Vehicle careClean 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-
coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.
Clean seat belts with lukewarm water or interior cleaner.Caution
Close Velcro fasteners as open
Velcro fasteners on clothing could
damage seat upholstery.
The same applies to clothing with
sharp-edged objects, like zips or
belts or studded jeans.
Plastic and rubber parts
Plastic and rubber parts can be
cleaned with the same cleaner as
used to clean the body. Use interior cleaner if necessary. Do not use any
other agent. Avoid solvents and petrol in particular. Do not use high-
pressure jet cleaners.

268Customer informationVehicle data recording
and privacy
Event data recorders
Electronic control units are installed in
your vehicle. Control units process
data which is received by vehicle
sensors, for example, or which they
generate themselves or exchange
amongst themselves. Some control
units are necessary for the safe
functioning of your vehicle, others
assist you while you drive (driver
assistance systems), while others
provide comfort or infotainment
functions.
The following contains general
information about data processing in
the vehicle. You will find additional
information as to which specific data
is uploaded, stored and passed on to third parties and for what purpose in
your vehicle under the key word Data Protection closely linked to the
references for the affected functional
characteristics in the relevant owner's manual or in the general terms of
sale. These are also available online.Operating data in the vehicle
Control units process data for
operation of the vehicle.
This data includes, for example: ● vehicle status information (e.g. speed, movement delay, lateral
acceleration, wheel rotation rate,
"seat belts fastened" display)
● ambient conditions (e.g. temperature, rain sensor,
distance sensor)
As a rule such data is transient and is
not stored for longer than an
operational cycle, and only processed on board the vehicle itself. Often
control units include data storage
(including the vehicle key). This is
used to allow information to be
documented temporarily or
permanently on vehicle condition,
component stress, maintenance
requirements and technical events
and errors.Depending on technical equipment
levels, the data stored is as follows:
● system component operating states (e.g. fill level, tyre
pressure, battery status)
● faults and defects in important system components (e.g. lights,
brakes)
● system reactions in special driving situations (e.g. triggering
of an airbag, actuation of the
stability control systems)
● information on events damaging the vehicle
● for electric vehicles the amount of
charge in the high-voltage
battery, estimated range
In special cases (e.g. if the vehicle
has detected a malfunction), it may be
necessary to save data that would
otherwise just be volatile.
When you use services (e.g. repairs,
maintenance), the operating data
saved can be read together with the
vehicle identification number and
used where necessary. Staff working
for the service network ( e.g. garages,
manufacturers) or third parties (e.g.
