It is strongly recommended that before you leave, you practise fitting the snow
c
hains on a level and dry sur face.
Snow chains
In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when braking.
T he snow chains must be fitted only
t
o the front wheels. They must never
b
e fitted to "space-saver" type spare
wheels.
Take
account of the legislation in force
i
n your country on the use of snow
chains
and the maximum running
s
peed
a
uthorised.
Avoid
driving with snow chains on
r
oads that have been cleared of snow,
to
avoid damaging your vehicle's tyres
a
nd the road sur face. If your vehicle
i
s fitted with alloy wheels, check that
n
o part of the chain or its fixings is in
c
ontact with the wheel rim.
Advice on installation
F If you have to fit the chains during a journey, stop the vehicle on a flat sur face on the side of the r
oad.
F
A
