Control indicator w in yellow as fault
message
w
If control indicator illuminates yellow
while driving, there is a fault in the tyre
pressure monitoring system. Fitting a wheel
without a pressure sensor (e.g. the spare
wheel 3) will also generate a fault in the
system. Have the cause of the fault
remedied by a workshop. The system's
integrated self-diagnostics allows faults to
be quickly remedied.
General information
The tyre pressure monitoring system is not
ready for operation if the emergency/spare
wheel is used and is not fitted with a
pressure sensor; the control indicator
illuminates yellow. The tyre pressure
monitoring system remains operational for
the other three wheels.
If you use a complete set of wheels which
are not fitted with sensors for the tyre
pressure monitoring system, e.g. four
winter tyres or aftermarket tyres of a
different size, no fault message will be
displayed. The tyre pressure monitoring
system is not ready for operation.
Sensors for the tyre pressure monitoring
system can be retrofitted by a workshop
upon request.
Driving and operation
When manually checking tyre pressure with
a pressure gauge, screw the adapter onto
the valve. Tyre pressure – see page 213.
Every time a tyre is changed, the valve
w
inserts and tyre pressure monitoring
system sealing rings must be replaced by a
workshop.
The use of commercially available liquid
filled run-flat systems or repair kits can
impair the function of the system.
Vauxhall-approved systems can be used.
Radio transmitters (e.g. radio headphones,
walkie-talkies) operated in the area could
cause interference in the tyre pressure
monitoring system.
