Vehicle care223Headlight wiringAn 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
heavy snow or ice, the windscreen
wipers will stop until the motor cools
down and the wiper control is turned
off. After removal of the blockage, the wiper motor will restart when moving
the control to the desired operating
position.
Although the circuit is protected from electrical overload, 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:
● in the front left of the engine compartment
● on the left side of the instrument panel
Before replacing a fuse, turn off the respective switch and the vehicle.
A blown fuse can be recognised by its melted wire. Do not replace the fuse
until the cause of the fault has been
remedied.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.
Fuse extractor
A fuse extractor may be located in the
fuse box in the engine compartment.

224Vehicle care
Place the fuse extractor on the
various types of fuse from the top or
side, and withdraw fuse.
Engine compartment fuse
box
The fuse box is located the left front
side of the engine compartment.
To open the fuse block cover, press
the clips at the front and back, then
rotate the cover up to the side.

Vehicle care237Temporary spare wheel
The use of tyre chains is not permitted on the temporary spare wheel.Jump starting
Do not start with quick charger.
A vehicle with a discharged vehicle
battery can be started using jump
leads and the vehicle battery of
another vehicle.9 Danger
The high voltage battery cannot be
jump started either with another
vehicle or battery charger.
Personal injury, death, or damage
to the vehicle could result.
9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.
9 Warning
Never jump start another vehicle
by using the terminals located in
the engine compartment.
This could cause a fuse to
overload in the vehicle.
● Never expose the vehicle battery
to naked flames or sparks.
● A discharged vehicle battery can already freeze at a temperature
of 0 °C. Defrost the frozen vehicle
battery before connecting jump
leads.
● Wear eye protection and protective clothing when
handling a vehicle battery.
Page 240 of 265

238Vehicle care● Use a booster vehicle batterywith the same voltage (12 Volt).
Its capacity (Ah) must not be much less than that of the
discharged vehicle battery.
● Use jump leads with insulated terminals and a cross section of
at least 16 mm 2
.
● Do not disconnect the discharged
vehicle battery from the vehicle.
● Switch off all unnecessary electrical consumers.
● Do not lean over the vehicle battery during jump starting.
● Do not allow the terminals of one
lead to touch those of the other
lead.
● The vehicles must not come into contact with each other during
the jump starting process.
● Apply the parking brake, shift lever in P.
● Open the positive terminal protection cap of both batteries.Battery terminals in the engine
compartment
The battery terminals to jump start the
vehicle are located in the engine
compartment.
The positive battery terminal is
located below a cover. Open the
cover before jump starting the
vehicle.
The negative battery terminal is stud
on a bracket located near the charger
modules.
Jump starting the vehicle
Lead connection order:
1. Connect the red lead to the positive terminal of the booster
vehicle battery.
2. Connect the other end of the red lead to the positive terminal of
your vehicle.
3. Connect the black lead to the negative terminal of the booster
vehicle battery.
4. Connect the other end of the black
lead to the negative battery
terminal (stud).

Vehicle care239Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the vehicle: 1. Start the engine of the vehicle providing the jump.
2. After five minutes, press POWER m to switch on the
vehicle.
After the instrument cluster
initialises, the vehicle will use
power from the high voltage
battery to charge the 12-volt
battery.
3. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
4. Reverse above sequence exactly when removing leads.Towing
Towing the vehicleCaution
Incorrect towing of a disabled
vehicle may cause damage to the
vehicle. The disabled vehicle
should only be towed on a flatbed
car carrier.
Ensure the vehicle is only towed
by well trained technicians.
Insert a screwdriver in the slot at the
short edge of the cap. Release the
cap by carefully moving the
screwdriver sidewards. To prevent
damage, it is recommended to place
a cloth between the screwdriver and
the frame.
The towing eye is stowed with the vehicle tools 3 230.
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.

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.
