Partial Monitoring
If a spare wheel without a wheel sensor is mounted in the event of a flat
wheel, a unique allocation of the remaining wheel electronics units can
still be detected by the trigger system. In this case, the system remains
active both when an emergency spare wheel or a spare wheel with no
wheel sensor is used, as well as if one or two sensors fail (e.g. due to
sealant) and continues to monitor the wheels using the wheel electronics
units that are still active.
Note
If a spare wheel with a wheel sensor is mounted in the event of a flat
wheel and if this is confirmed by selecting “Spare wheel” is the Spare
wheel menu, this wheel will be incorporated into the monitoring process
following a brief learning phase.
System Cannot be Switched Off, Warning can be Acknowledged
The TPM system can no longer be switched off. As a result, if the
pressure is deliberately reduced well below the nominal pressure, e.g.
for improved traction on extremely soft or sandy terrain, a flat wheel
message will appear continuously in the display.
The hard (red) warning can be acknowledged with the new TPM genera-
tion. This clears the display so that any other messages and/or informa-
tion can be shown. The TPM light in the instrument panel remains
activated until the tire pressure is increased to the nominal pressure.
Each time the ignition is switched off and on again, the hard warning
re-appears as a reminder and can be acknowledged again if necessary.
