Fuses Data on the replacement fuse must
match the data on the defective fuse.
There are three fuse boxes in the
vehicle:
● engine compartment
● instrument panel
● load compartment
Before replacing a fuse, turn off the
respective switch and the ignition.
A blown fuse can be recognized by its melted wire. 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.

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 3 289.
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 3 295.
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:
● Identify the engine identifier code. Engine data 3 287.
● Identify the respective tyre. ● The tyre pressure tables show all
possible tyre combinations
3 295.
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.

Vehicle care2579Warning
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.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Temperature dependency
The tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Tyre pressure
values provided on the tyre
information label and tyre pressure
chart are valid for cold tyres, which means at 20 °C.
The pressure increases by nearly
10 kPa for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
The tyre pressure value displayed in
the Driver Information Centre shows
the real tyre pressure. A cooled down tyre will show a decreased value,which does not indicate an air leak.
Tyre pressure monitoringsystem
The tyre pressure monitoring system
checks the pressure of all four tyres
once a minute when vehicle speed
exceeds a certain limit.Caution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Note
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle operating permit.
The current tyre pressures can be
shown in the Driver Information
Centre.
Midlevel display:
Select the Tyre pressure page under
the Vehicle Information Menu ? in
the Driver Information Centre 3 115.
