hub caps. Remove the hub caps from the rel-
evant wheels before fitting the snow
chains.
smart recommends that you only use snow
chains that have been specially approved for
smart. For more information, please contact
the smart centre or a qualified specialist
workshop.
If you intend to fit snow chains, please bear
the following points in mind:
R
snow chains cannot be fitted to all wheel-
tyre combinations. Permissible wheel-
tyre combinations (
Y
page 210).
R
only use snow chains when the road surface
is completely snow-covered. Remove the
snow chains as soon as possible when you
come to a road that is not snow-covered.
R
local regulations may restrict the use of
snow chains. Observe the appropriate reg-
ulations if you wish to fit snow chains.
R
do not exceed the maximum permissible
speed of 50 km/h.

WARNING
Underinflated or overinflated tyres pose
the following risks:
R
the tyres may burst, especially as the
load and vehicle speed increase.
R
the tyres may wear excessively and/or
unevenly, which may greatly impair tyre
traction.
R
the driving characteristics, as well as
steering and braking, may be greatly
impaired.
There is a risk of an accident.
Observe the recommended tyre pressure and
check the tyre pressure of all the tyres:
R
at least every two weeks
R
when the load changes
R
before embarking on a longer journey
R
for changed operating conditions, e.g.
off-road driving
If necessary, correct the tyre pressure.
G
WARNING
If you mount unsuitable accessories onto
tyre valves, the tyre valves may be overloa-
ded and malfunction, which can cause tyre
pressure loss. Aftermarket tyre pressure
monitoring systems will cause the tyre
valve to remain open. This can also result
in tyre pressure loss. There is a risk of an
accident.
Only screw standard valve caps or valve
caps specifically approved by smart for
your vehicle onto the tyre valve.
G
WARNING
If the tyre pressure drops repeatedly, the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in a tyre
blow-out. There is a risk of accident.
R
Check the tyre for foreign objects.
R
Check whether the wheel is losing air or
the valve is leaking.
If you are unable to rectify the damage,
contact a qualified specialist workshop.
H
Environmental note
Check the tyre pressure regularly, at least
every 14 days.
You will find a table with the recommended
tyre pressure on the tyre pressure table on the
driver's side B-pillar.
Additionally, the tyre pressure table may
also state tyre pressures for different load
conditions. These are defined in the table as
different numbers of passengers and amounts
of luggage. The actual number of seats may
vary; for more information, please refer to
the vehicle's registration documents.
If tyre sizes are not specified, the tyre pres-
sures stated on the tyre pressure table apply
for all tyres approved for this vehicle.
