General
Dynamic Stability Control DSC is activated if
necessary as soon as the message for a flat tyre
appears.
Safety note
WARNING
A damaged standard tyre with too little or no
tyre inflation pressure impairs driving character‐
istics, for example steering and braking. Tyres
with run-flat properties allow a limited level of
stability to be maintained. There is a risk of ac‐
cident. Do not continue driving if the vehicle is
fitted with normal tyres. Comply with the notes
on run-flat tyres and continuing to drive with
these tyres.
Flat tyre message
A yellow warning lamp is illuminated in
the instrument cluster.
In addition, a symbol with a Check Control mes‐
sage is shown on the Control Display.
Symbol Possible cause
There is a flat tyre or substantial loss
of tyre inflation pressure.
Measure
1. Reduce your speed and carefully stop the ve‐
hicle. Avoid heavy braking and sudden steer‐
ing manoeuvres.
2. Check whether the vehicle is equipped with
standard tyres or run-flat tyres.

Safety notes
A run-flat tyre which has low tyre inflation pres‐
sure or no tyre inflation pressure at all will
change the vehicle's handling characteristics,
for example there may be reduced directional
stability when braking, longer braking distances
and different self-steering characteristics.
There is a risk of accident. Drive with care and
do not exceed a speed of 80 km/h, 50 mph.
Continuing to drive with a flat tyre can result in
heavy trailers starting to slalom. There is a dan‐
ger of accidents or damage to property. When
driving with a trailer and a flat tyre, do not ex‐

The symbol identifying run-flat tyres, see
page 341, is a circle with the letters RSC on
the tyre side wall.
Identify the damaged tyre.
To do this, check the tyre inflation pressure in
all four tyres, for example using the tyre pres‐
sure indicator of a flat tyre kit.
If all four tyres are inflated to the correct tyre
inflation pressures, the runflat indicator might
not have been initialised. In this case initialise
the system.
If it is not possible to identify tyre damage,
contact a Service Partner of the manufacturer
or another qualified Service Partner or a spe‐
cialist workshop.
Repair the flat tyre, for example using a flat
tyre kit or by changing the wheel.
