Meaning/measure
No RDK (tire pressure) monitoring
External interference or excessive temperatures
(above 250°F/120°C) at the wheel sensors will cause
the system to switch off temporarily.
The tyres are temporarily not monitored.
Fault when setting the tire pressure
The pressures set on one axle deviate significantly (at
least 6 psi/0.4 bar) from each other.
Fault when setting the tire pressure
At least one of the set pressures for driving on the
race track is below 25 psi/1.7 bar actual pressure
and is thus too low.
The Tire pressure menu can only be called up when
the vehicle is stationary.
