Tyre-pressure monitoring system reset and calibration guidance.
Reset or calibrate the tyre monitor
Requirements:
• The recommended tyre pressure is correctly set for the respective operating condition on each of the wheels.
• Restart the tyre pressure monitoring system in the following situations:
- The tyre pressure has changed.
- The wheels or tyres have been changed or newly fitted.
On-board computer:
► Service ► Tyres
► Scroll down in the menu.
► The Use current pressures as new reference values? message appears in the multifunction display.
► Confirm the message to initiate a restart.
The Tyre press. monitor restarted message appears in the multifunction display.
Current warning messages are deleted and the flat tyre yellow warning lamp goes out.
After you have driven for a few minutes, the system checks whether the current tyre pressures are within the specified range. The current tyre pressures are then accepted as reference values and monitored.
Before resetting the system
Set all tyres on the Mercedes Sprinter Twin Rear to the correct cold pressures first. Resetting the monitor with an incorrectly inflated tyre can store an unsafe reference value.
How tyre-pressure monitoring systems work
Direct TPMS uses a pressure sensor inside each wheel. It can usually identify a pressure loss before the vehicle moves and may show individual tyre pressures on the dashboard. Sensor replacement or relearning can sometimes require specialist equipment.
Indirect TPMS uses the ABS wheel-speed sensors to identify a tyre whose rolling circumference has changed. This system normally needs recalibrating after tyre pressures are adjusted, tyres are replaced or wheels are moved.
Dashboard wording and reset steps vary between trim levels and software versions. Follow the vehicle’s on-screen instructions and owner’s manual where they differ from the guidance above.
