Tire Monitoring System: Service and Repair




System Learning

Tire Pressure Monitoring begins to "learn" the wheels after a wheel change, wheel transmitter replacement or update of the tire settings. During this process, Tire Pressure Monitoring recognizes the wheels and their locations.

The message "No monitoring, system is learning" (example) appears on the multi-purpose display.

The wheel learning process takes place exclusively when the vehicle is being driven (vehicle speed above 16 mph (25 km/h)).

Tire Pressure Monitoring requires a certain amount of time to learn the wheels. During this time, the current tire pressures are not available on the multi-purpose display:
- The tire pressure warning light remains lit until all wheels have been learned.
- Lines (-.-) appear on the display of the "Tire pressure" function.
- The required pressures for cold tires (68 °F (20 °C)) are indicated under "Fill info" in the "Tire pressure" main menu.

Position and pressure information is displayed as soon as Tire Pressure Monitoring has assigned the wheels recognized as belonging to the vehicle to the correct wheel positions.
- Check the tire pressure for all wheels under "Fill info".
- Correct the tire pressure to the required pressure if necessary.
