Transmission Modes

The wheel electronics units communicate with the control unit in various modes. Depending on the current mode of a wheel electronics unit, it sends telegrams to the control unit at defined intervals.

• Normal mode  : Normal mode is active while the vehicle is driving (after Burst mode has ended).
• Sleep mode  : Sleep mode is activated as soon as the vehicle remains stationary for longer than 5 minutes. The wheel electronics then send no more telegrams. If the ignition is switched on while the wheel electronics units are in Sleep mode, no tyre pressures are displayed (display in instrument cluster: "-.-"). Tyre pressures are only displayed again when the vehicle is driving (see Burst mode).
• Burst mode  : If the wheel electronics units are in Sleep mode and the vehicle is accelerated to over 25 km/h (15 mph) from stationary, the wheel electronics units switch to Burst mode. The wheel electronics units send their telegrams for 60 seconds at fast intervals.
