174Vehicle careTyre pressure monitoring
system The vehicle may be fitted with a tyrepressure monitoring system or a tyre
deflation detection system 3 175.Caution
Modifications made to the tyre
pressure monitoring system
(TPMS) by anyone other than an
authorised service facility may
void authorisation to use the
system.
The tyre pressure monitoring system
checks the pressure of all four wheels once a minute when vehicle speed
exceeds a certain limit.
Caution
Tyre pressure monitoring system
warns only about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
Winter tyres or additional wheel sets
have to be fitted with sensors,
otherwise the system will not work
and the control indicator A illuminates
continuously.
If A lights up, stop as soon as
possible and inflate the tyres as
recommended 3 217.
After inflating, driving may be
required to extinguish A.
If A lights up at lower temperatures
and extinguishes after some driving,
this could be an early indicator for getting low pressure. Check tyre
pressure.
The tyre pressure monitoring system
malfunction indicator is combined
with the low tyre pressure controlindicator. If the system detects a
malfunction, the control indicator will
flash for approx. 1 minute and then
remain continuously illuminated. This sequence will continue upon
subsequent vehicle start‐ups as long as the malfunction exists.
A temporary spare wheel is not
equipped with a pressure sensor. The
tyre pressure monitoring system is
not operational for these wheels.
Control indicator A illuminates.
Operating electronic devices or being
near facilities using radio wave
frequencies similar to the tyre
pressure monitoring system could
cause the tyre pressure monitoring
system sensors to malfunction.
Tyre pressure monitoring system malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tyres or
wheels on the vehicle that prevent the tyre pressure monitoring system fromfunctioning properly. Always check
the tyre pressure monitoring system
malfunction control indicator after
replacing one or more tyres or wheels
