FUEL CONSUMPTION
The fuel consumption values shown in the following tables were established during homologation tests prescribed in specific European
Directives.
The test conditions adopted include the following:
–an urban cycle:this includes cold starting followed by simulation of a mixed urban route;
–an extraurban cycle:this includes frequent accelerating in all gears, simulating normal extraurban use of the vehicle; the speed
varies between 0 and 120 kph;
–combined consumption:this is calculated by considering a route consisting of about 37% urban cycle and 63% extraurban cy-
cle.
IMPORTANT The type of route, traffic conditions, weather conditions, driving style, conditions of the vehi-
cle, trim level/ equipment/ accessories, vehicle load, presence of a roof rack, other items that negatively
affect the aerodynamics of the vehicle or wind resistance may lead to different fuel consumption levels than
those measured by the above-mentioned procedures (see “Economy and environment-friendly driving” para-
graph in the “Getting the best out of your car” chapter).

SPARE WHEEL
Cars fitted with steel rims and tyres 215/55 R16 (*) have s-
pare wheel identical with the standard wheels. Cars fitted with a-
luminium alloy rims and tyres 215/55 R16 (*), 225/45 R17
and 235/40 R18 have the spare wheel with steel rim and tyre
215/55 R16 (*).
On cars fitted with tyres 215/55 R16 (*),
225/45 R17, 235/40 R18 and spare
wheel with tyre 215/55 R16 (*), since the spare
wheel is different from the standard wheels, observe
the instructions for use given below.
– The spare wheel should only be used in an emer-
gency.
– Use of the spare wheel should be kept to a mini-
mum. Do not drive at speeds of over 80 km/h.
– The car will handle differently when the spare
wheel is fitted. Avoid sudden acceleration or braking,
sharp corners and fast bends.
– Check at regular intervals that spare wheel pres-
sure is equal to 2.7 bar (2.7 kg/cm
2).
Two or more spare wheels should never be used to-
gether. Have the wheel changed repaired and refit-
ted as soon as possible.
WARNING

246
Note for one way tyres
There are arrows on the side of one-way
tyres indicating the direction of rotation.
When a wheel is changed (for example
after a puncture, the direction of the ar-
row on the spare wheel might not coin-
cide with the direction of rotation of the
wheel to be changed. Even in these con-
ditions the tyre is still safe but you are ad-
vised to have the tyre repaired and refit-
ted as soon as possible, because top per-
formance is obtained when all the wheels
turn in the direction of the arrow.NoteThe vehicles are fitted with tube-
less tyres. See chapter “Getting the best
out of your car” for indications concerning
tyres in general and the specific recom-
mendations for tubeless tyres. When re-
placing tyres and/or rims maintain the o-
riginal rim/tyre match.IMPORTANTTyre pressure should be
increased by 0.3 bars when driving at
sustained high speed. With winter tyres
the pressure should be +0.2 bar higher
than the rating specified for standard
tyres. Do not use inner tubes with tube-
less tyres.
Snow chains can be fitted
only on wheels with 6.5J x
16” rims and 215/55 R16
(*) tyres or 7.5J x 17” rims and
225/45 R17 tyres.
(*) For versions/markets where
applicable tyres 205/55 R16.

in perfect conditions and above all of the specified type and brand.

CORRECT TYRE READING
Below are the instructions necessary to know the meaning of
the code stamped on the tyre.
The code may be like one of the examples given below.

meaning of the markings on the rim, as shown in fig. 7.
6.5= Rim width in inches (1)
J= Rim drop centre outline (side projection where the tyre bead
rests) (2)
