9.7.7 Tire pressure monitoring
a
WARNING
Do not make any modifications in the area under the
floor of the vehicle, including the vehicle axles and
the system components of the tire pressure monitor.
Otherwise, the function of the tire pressure moni-
toring system may be compromised by the effects
of reflections. This might result in the driver being
unaware of any tire pressure loss, and he/she could
cause an accident. Furthermore, the vehicle may no
longer meet certification requirements.
National regulations must be complied with.
The system's reception module/control unit is affixed
to the outside, on the vehicle floor plate above the rear
axle differential. The pressure sensors are integrated
into the tire valves.
