Tyre monitoring system
Introduction
This chapter contains information on the followingsubjects:
Tyre Pressure Loss Indicator
Troub
The tyre monitoring system warns the driver when the tyre pressures are too low.
The tyre monitoring system monitors various parameters (for example, rolling circumference) of all
wheels using ABS sensors (indirect measurement).
WARNING
The intelligent tyre monitoring system technology cannot overcome the laws of physics, and
functions only within the limits of the system. Incorrect handling of the wheels and tyres can lead to
a sudden loss of pressure in the tyres, tread separation and even tyre blow-out.
