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.

Wheels and tyres
Tyre condition, wheel condition Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
Tyres
Self-sealing tyres This vehicle may have self-sealing
tyres. These tyres have a material
inside that can seal punctures up to
6 mm in the tread area.
The tyre may lose air pressure if the
sidewall is damaged or the tread
puncture is too large. If the Tyre
pressure monitoring system indicates the tyre pressure is low, inspect thetyre for damage and inflate it to the
recommended pressure. If the tyre is
