Locating the TPMS reset switch (typical).
The tire pressure monitoring system (TPMS) monitors the tire inflation pressure (as selected by the driver) in the four road tires of the Mercedes-Benz M Class subject vehicles. To perform this function, the system uses an electronic tire pressure sensor in each wheel, and a low tire pressure warning light on the instrument cluster.
The wheel sensor is mounted on the metal valve (not visible from outside), and measures the air pressure and temperature inside the tire.
Tire pressure monitor warning indicators
If the warning light is on and the multifunction display shows a message, immediately check air pressure of all tires and adjust to the specified pressure. Reactivate the TPMS. Drive the vehicle for a few minutes to ensure the malfunction has been corrected. If the warning light stays on or flashes, there is a malfunction in the TPMS. See the appropriate manufacturer service information. The warning light will illuminate in the following ways to indicate a low tire pressure condition or a malfunction in the TPMS:
- If the warning light is on continuously, one or more of the tires is significantly under-inflated. There is no problem in the TPMS.
- If the warning light flashes for 60 seconds and then stays illuminated, there is a problem in the TPMS. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.
NOTE: If a condition causing the TPMS to malfunction develops, it may take up to 10 minutes for the system to signal a malfunction using the warning light flashing and illumination sequence.
