Wheels and tyres
Run-flat tyres*
Run-flat tyres allow you to continue driving even with a punc-
tured tyre, in the majority of cases.
In vehicles that are factory-fitted with run-flat tyres
pressure is indicated on the instrument panel.
Driving with run-flat tyres (emergency running)
– Leave the ESP/TCS (Electronic Stability Programme) switched on,
or switch on ⇒ page 68.
– Continue driving carefully and slowly (80 km/h maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Look out for the ESP/TCS intervening often, smoke coming from
the tyres or the smell of rubber, the vehicle vibrating or a clat-
tering noise. If any of these occur, stop the vehicle.
The run-flat tyres have a tag on the side of the tyre, with the description:
"DSST", "Eufonia", "RFT", "ROF", "RSC", "SSR" or "ZP".
The sides of this type of tyre are reinforced. When the tyres lose air they are
supported on the sides (emergency driving).
The loss of pressure in the tyre is shown on the instrument panel. You can
then drive a maximum of 80 km and if the circumstances are favourable (for
example, low load), even more.
The damaged tyre should be changed as soon as possible. The rim should be
checked in a specialist workshop to detect possible damage and replace it if

necessary. We recommend you contact Technical Service. If more than one
tyre is being used under emergency conditions, this reduces the distance
which can be travelled.

End of emergency operation
Do not drive on if:
•
smoke is coming from one of the tyres,
•
there is a smell of rubber,
•
the vehicle vibrates,
•
there is a rattling noise.
When is it no longer possible to continue driving even using run-flat tyres?
•
If the Electronic Stability Programme (ESP) is out of operation.
•
If the tyre pressure monitoring system* does not work.
•
If one of the tyres has been severely damaged in an accident, etc. If a tyre
has been badly damaged there is a risk that parts of the tread can be thrown
off and cause damage to the fuel lines, brake pipes or fuel filler.
•
It is also advisable to stop driving if severe vibrations occur, or if the wheel
starts overheating and gives off smoke.
WARNING
When driving in emergency conditions, the driving quality of the vehicle is
considerably impaired.
•
The maximum permitted speed of 80 km/h is subject to road and
weather conditions. Please observe legal requirements when doing so.
•
Avoid sharp turns and rapid manoeuvres, and brake earlier than usual.
•
Avoid driving over obstacles (for example kerbs) or potholes.
