USING THE VEHICLE
TYRESTYRE INFLATION
PRESSURE WHEN COLD
The tyre inflating ratings shown in this manual
must be read as values applicable with cold
tyres.
CAUTION
When winter tyres are fitted,
it is advisable not to exceed a speed
of 220 km/h. Always observe the
regulations in force in the country
where you are driving and follow
the instructions provided by the tyre
manufacturer.
CAUTION
When using the spare wheel
(emergency wheel) do not exceed 80
km/h. Avoid driving at full throttle,
braking sharply and cornering at high
speeds.
WINTER TYRES
These tyres are specially designed for driving on
snow and ice and are fitted to replace the ones
supplied with the vehicle.
CAUTION
Only use winter tyres having
the same dimensions as those provided
with the vehicle or as indicated on
page 186.
The Authorised Service Centres of the
Manufacturer’s Network are available to
provide suggestions as to the types of tyres most
suited to the use foreseen by the Customer.
For the type of tyres to use, inflation pressures
and relative specifications for winter tyres,
carefully follow the indications found in the
section “Capacities and technical specifications”.
The features of these tyres are markedly reduced
in winter when tread depth is less than 4 mm. In
this case, they should be replaced.The specific features of the winter tyres lead to
lower performance under normal environmental
conditions or on long highway trips, compared to
the standard tyres.
Therefore, they should only be fitted for
their intended use, for which they have been
approved.
CAUTION
Fit identical (manufacturer and
tread) tyres on all four wheels, in
order to ensure safe driving, braking
and good manoeuvrability.
CAUTION
Remember that the direction of
tyre rotation should not be reversed.

CAPACITIES AND TECHNICAL SPECIFICATIONS
FUEL
CONSUMPTIONThe fuel consumption values shown in the
following table were established based on
homologation tests prescribed by specific
European Directives.
The test procedures followed for fuel
consumption measuring are described below:
- City cycle: This test begins with a cold start,
followed by simulation of an urban route;
- Highway cycle: This test involves frequent
accelerations in all gears, simulating use of
the vehicle on routes outside urban areas;
the speed varies between 0 and 120 km/h
- Average fuel consumption: This is
calculated considering a route consisting
of about 37% city cycle and 63% highway
cycle.FUEL CONSUMPTION FOLLOWING THE 2004/3/EC
DIRECTIVE (LITRES PER 100 KM)
City Highway Average
23.6 11.4 15.8WARNING: The type of route, traffic and weather conditions, driving style, general condition of the
vehicle, equipment/accessories in the vehicle, use of the air conditioning system, vehicle load and other
items or situations which may negatively affect the vehicle aerodynamics or wind resistance lead to
consumption ratios differing from the indicated ones.CO
