234Vehicle careWinter tyres or additional wheel sets
must be fitted with sensors, otherwise the system will not work and control
indicator w illuminates continuously.
The tyre pressure monitoring system
malfunction indicator is combined
with the low tyre pressure control
indicator. If the system detects a
malfunction, w will flash for approx.
one minute and then remain
continuously illuminated. This
sequence will continue upon
subsequent vehicle start-ups as long
as the malfunction exists.
If the malfunction indicator w is
illuminated, the system may not be
able to detect or signal low tyre
pressure as intended. 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 w after
replacing one or more tyres or wheels
on your vehicle to ensure that thereplacement or alternative tyres and
wheels allow the tyre pressure
monitoring system to continue to
function properly.
A temporary spare wheel is not
equipped with a pressure sensor. The
tyre pressure monitoring system is
not operational for these wheels.
Control indicator w illuminates. For
the further three wheels the system
remains operational.
A full size spare wheel is equipped
with a pressure sensor. The system
will detect the new wheel
automatically during driving.
The use of commercially-available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
Operating electronic devices or being
close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.
Each time the tyres are replaced, tyre pressure monitoring system sensors
must be dismounted and serviced.
For the screwed sensor, replacevalve core and sealing ring. For the
clipped sensor, replace complete
valve stem.
Vehicle loading status
Adjust tyre pressure to load condition according to the tyre information label
or tyre pressure chart 3 251, and
select the appropriate setting in the menu Tyre load in the Options menu
in the Driver Information Centre 3 82.
This setting is the reference for the
tyre pressure warnings.
