2. At the next opportunity, for example at a filling
station, check the tyre inflation pressure in all
four tyres and correct if necessary.

inflation pressure
Message

Messages: in the case of tyres
with special approval
General
Dynamic Stability Control DSC will be activated if
necessary as soon as a message for low tyre in‐
flation pressure appears.
Safety note
WARNING
A damaged normal tyre with too little or no tyre
inflation pressure impairs driving characteris‐
tics, for example steering and braking. Tyres
with run-flat properties allow a limited level of
stability to be maintained. There is a danger of
accidents. 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.
If a tyre inflation pressure test is
required
Message
A symbol with a Check Control message is
shown on the Control Display.
