In this case reduce speed, avoid sharp
cornering and strong braking.
3. Initialise the system via the
Speed limit system (compliant
with the European General Safety
Regulation)
This system displays permanently
speed limit information on the cluster
independent of the vehicle speed.
Providing the speed limit information
involves the following systems,
depending on version:
Information Display ðpage58
Stop at next safe opportunity and check
tyre pressure.
4. Reset is confirmed by a message.
After initialisation the system
automatically calibrates to new tyre
pressures during driving. After a longer
drive the system will adopt and monitor
new pressures.
Always check tyre pressure with cold
tyres.
The system must be reinitialised when:
After adjusting tyre pressure initialise the
system to extinguish the control indicator
and restart the system.
If the failure continues to be displayed,
contact a workshop. The system is
inoperable when the ABS or Electronic
Stability Control has a malfunction or a
temporary spare wheel is used. Once
the tyre has been refitted, check the tyre
pressure with cold tyres and initialise the
system.

If travelling on a road with no speed
restrictions, e.g., on German motorways,
the following sign is displayed:
● Tire pressure has been changed.
● Load condition has been changed.
● Wheels have been swapped or

exchanged.
Tyre deflation detection system warns
just about low tyre pressure condition
and does not replace regular tyre
maintenance by the driver.
The system will not warn instantaneously
on a tyre blow out or a rapid deflation.
This is due to required calculation time.

Traffic Sign Assist (TSA)
If no speed limit information can be
provided, the following sign is displayed:
After tyre pressure correction or wheel
change, the system must be initialised
to learn new circumference reference
values:
Warning
The actual traffic sign always takes
priority over the traffic sign displayed on
the cluster.
1. Always ensure that all four tyres have
correct tyre pressure ðpage170
2. Apply parking brake.
If a new speed limit is provided, a
confirmation chime is given, when the
