❒The performance of the parking assistance
system may also be affected by the position of
the sensors. For example, if the geometry is
altered (as a result of wear of the shock
absorbers, suspension), the tyres are changed,
the vehicle is too heavily laden or specific tuning
is carried out that lowers the vehicle.
❒The detection of obstacles at the top part of the
car may not be guaranteed because the system
detects obstacles that could cause an impact with
the car in the bottom part.
AT THE FILLING STATIONPETROL ENGINES
Use unleaded petrol only, with octane number
(R.O.N.) not lower than 95.
To avoid mistakes, the diameter of the fuel filler is
too small to introduce the nozzle of leaded petrol
pumps.
IMPORTANT An inefficient catalytic converter
leads to harmful exhaust emissions, thus
contributing to air pollution.
IMPORTANT Never use leaded petrol, even in
small amounts or in an emergency, as this would
damage the catalytic converter beyond repair.
MOTORI DIESEL - Operation at low
temperatures
If the outside temperature is very low, diesel
thickens due to the formation of paraffin clots with
consequent defective operation of the fuel supply
system.
In order to avoid these problems, different types of
diesel are distributed according to the season:
summer type, winter type and arctic type
(cold/mountain areas). If refuelling with diesel fuel
whose specifications are not suitable for the
current temperature, it is advisable to mix TUTELA
DIESEL ART additive in the proportions shown on

SNOW TYRESUse snow tyres of the same size as the normal
tyres provided with the car.
A Fiat Dealership will be happy to provide advice
concerning the most suitable type of tyre for
the customer's requirements.
For the type of tyre to be used, inflation pressures
and the specifications of snow tyres, follow the
instructions given in paragraph "Wheels" in section
"Technical specifications".
The winter features of these tyres are reduced
considerably when the tread depth is below 4 mm.
Replace them in this case.
Due to snow tyre features, under normal
conditions of use or on long motorway journeys,
the performance of these tyres is much lower than
that of standard tyres. Their usage should therefore
be restricted in accordance with their type
approval.IMPORTANT When using snow tyres with a
maximum speed index below the one that can be
reached by the car (increased by 5%), place a notice
in the passenger compartment, plainly in view,
which states the maximum speed allowed by the
snow tyres (as per EC Directive).
All four tyres should be the same (brand and track)
to ensure greater safety when driving and braking
and better driveability.
Remember that you should not change the rotation
direction of the tyres.
WARNING
The maximum speed for snow tyres
marked “Q” is 160 km/h, while it is 190
km/h for “T” tyres and 210 km/h for "H" tyres.
You should, however, always stick to the speed
limits of the Road Traffic Code.
