SNOW TYRES
200)
Use snow tyres of the same size as the
standard tyres provided with the car.
All four tyres should be the same (brand
and track) to ensure greater safety
when driving and braking as well as a
good manoeuvrability.
Remember that you should not change
the rotation direction of the tyres.
The Fiat Dealership will be happy to
provide advice concerning the most
suitable type of tyre for the customer's
requirements.
The winter performance of these tyres
is considerably reduced when the tread
thickness is less than 4 mm. Replace
them in this case.
Due to the specific characteristics of
snow tyres, in normal weather
conditions or on long motorway
journeys, the performance of these
tyres is 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
as well as a good manoeuvrability.
Remember that you should not change
the rotation direction of the tyres.
SNOW CHAINS
67) 68) 69)
The use of snow chains should be in
compliance with local regulations of
each country. In certain countries, tyres
marked with code M+S (Mud and
Snow) are considered as winter
equipment; therefore their use is
equivalent to that of the snow chains.
Snow chains can be fitted to the tyres
of the front wheels (drive wheels) only.
Check the tension of the snow chains
after the first few metres have been
driven.
Using snow chains with tyres with
non-original dimensions may damage
the vehicle.
Using different size or type (M+S, snow,
etc.) tyres between front and rear axle
may adversely affect car driveability,
with the risk of losing control of the car
and resulting accidents.
IMPORTANT Snow chains cannot be
fitted to the space-saver wheel. If a
front tyre is punctured, replace a rear
wheel with the space-saver wheel and
move the rear wheel to the front axle. In
this way, with two normal drive wheels
at the front, snow chains can be fitted.
WARNING
193) The space-saver wheel (for
versions/markets where provided) is
specific to your car, do not use it on other
models, or use the space-saver wheel
of other models on your car. The
space-saver wheel must only be used in
the event of an emergency. Never use it for
more than strictly necessary and never
exceed a speed of 80 km/h.
194) Snow chains cannot be fitted to the
space-saver wheel. So, if a front (drive)
wheel is punctured and chains are needed,
a rear wheel should be fitted to the front
of the car and the space-saver wheel
should be fitted to the rear. In this way,
equipped with two normal drive wheels at
the front, they can be fitted with snow
chains, thus resolving the emergency
situation
