216Vehicle careElectrical systemFuses
Data on the replacement fuse must
match the data on the defective fuse.
There are two fuse boxes in the
vehicle:
● engine compartment● 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.
Fuse extractor
A fuse extractor may be located in
front of the fuse box in the instrument
panel.Place the fuse extractor on the
various types of fuse from the top or
side, and withdraw fuse.

Vehicles with spare wheel Open the floor cover of the load
compartment 3 73.
Remove the cover of the tool box.
The jack, the towing eye, chocks and
the tools are located in the tool box.
Vehicles without spare wheel
The towing eye and the chocks are
located in a box below the floor cover in the load 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.
Winter tyres
Winter tyres improve driving safety at temperatures below 7 °C and should
therefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.
All tyre sizes are permitted as winter
tyres 3 254.Tyre designations
E.g. 225/55 R 18 98 V225:tyre width, mm55:cross-section ratio (tyre height
to tyre width), %R:belt type: RadialRF:type: RunFlat18:wheel diameter, inches98:load index e.g. 98 is equivalent

Choose a tyre appropriate for the
maximum speed of your vehicle.
The maximum speed is achievable at kerb weight with driver (75 kg) plus
125 kg payload. Optional equipment
could reduce the maximum speed of
the vehicle.
Performance 3 250.

222Vehicle careDirectional tyres
Directional tyres should be mounted so that they rotate in the correct
direction. The proper rotation
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
Tyre pressure 3 254.
The tyre pressure information label
on the left door frame indicates the
original equipment tyres and the
correspondent tyre pressures.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 249.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 254.For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
