Safety
Do not continue a journey without run-
flat tyres
Maximum possible distance with tyres entirely
deflated:
Do not continue your journey if the vehicle is
not equipped with run-flat tyres, otherwise a
serious accident could occur.◀
The possible distance with a puncture de‐
pends on the load and strain on the vehicle
during the journey.
When the vehicle is subject to medium load,
the possible distance is approx. 80 km,
50 miles.
It is possible that Dynamic Stability Control
DSC is activated as soon as the message for a
puncture appears.
When driving with damaged tyres, the vehicle
handling changes, for example quicker loss of
traction when braking, longer stopping dis‐
tance and modified self-steering behaviour.
Adapt driving style accordingly. Avoid abrupt
steering or driving over obstacles, for example
curbs, potholes etc.
What to do in the event of a puncture
Standard tyres
1. Identify the damaged tyre.
Do this by checking the air pressure in all
four tyres.
As the possible distance largely depends on
the strain on the vehicle during the journey,
this can be shorter, or longer if the vehicle is
driven carefully, according to speed, road con‐
dition, outside temperature, load etc.
If the pressure of all four tyres is correct,
the Tire Pressure Monitor may not have
been reset. Then reset the system.
If it is not possible to identify, contact a
Service centre.
Continuing a journey with a flat tyre
2. Fix the puncture.
Drive with care and do not exceed a
speed of 80 km/h, 50 mph.
Tyre sealants can damage the TPM wheel
electronics. Check the electronics at the
next opportunity and adjust it if necessary.
If tyre pressure has fallen, vehicle handling
changes, for example reduced directional sta‐
bility when braking, longer stopping distance
and modified self-steering behaviour.◀
Run-flat tyres
If a tyre has punctured you can continue your
journey, driving at speeds up to a maximum of
80 km/h, 50 mph.
Final tyre failure
Vibration or loud noises while driving
may be an indication that the tyre has finally
failed. Reduce your speed and stop, otherwise
sections of the tyre could become detached
and cause an accident. Do not drive the car
any further; contact your Service Centre in‐
stead.◀
Continuing a journey with a puncture
If you continue a journey with a puncture:
1. Avoid violent or sudden braking and steer‐
ing manoeuvres.
2. Do not exceed a speed of 80 km/h, 50 mph
any longer.
System limits
3. As soon as you get an opportunity, check
the tyre pressure in all four tyres.
The system does not work properly if a reset
hasn't been carried out (e.g. a puncture is re‐
ported although the tyre pressures are cor‐
rect).
If the pressure of all four tyres is correct,
the Tire Pressure Monitor may not have
been reset. Then reset the system.
