Notes on Tire Mounting/Dismounting with Tire Pressure Monitoring Systems
Please note that improper tire replacement (mounting/dismounting) may affect the functionality of the tire pressure monitoring wheel sensor and/or it
may be damaged mechanically
This can lead to a tire pressure monitoring system failure. The wheel sensor must be replaced as a result.
Note:
In order to avoid damages these instructions must be strictly observed:
The components from the various suppliers are not compatible with one another. In the case of incorrect or mixed fitment of individual components
(such as wheel sensors) the tire pressure monitoring system will no longer function.
It is therefore critical that when replacing a wheel sensor and/or tire that only wheel sensors of the respective system manufacturer and the correct
frequency are used.
As a rule damage caused during assembly operations is not recognized immediately. Therefore a visual inspection of the wheel sensors in particular after
dismounting the tires is critical. Based on this fact it is essential to observe the following information during the tire mounting and dismounting process.
Note:
Damaged Sensors cannot be claimed under warranty.
Identification of wheels with tire pressure monitoring sensors:
For mounting the wheel sensors Mercedes-Benz uses a tire inflation valve made from aluminum (A) in place of a steel valve (B) or rubber valve (C).
(Figure 1)
Note:
Aluminum valve stems can only be used once and must be replaced in their entirety when changing wheels and/or sensors.
