System initialisation
The system must be initialised after a
wheel/tyre change:
With the ig nition switched on, press button
DDS approx. 4 seconds. Control indicator
w
flashes 3 tim es. The system is operational
after driv ing a certain distance.
Only initialise the system if all tyres have
the p rescrib ed pressure (c heck w hen tyres
are cold).
General information
The tyre pressure monitoring system does
not function when the emergency or a
spare wheel not fitted w ith a pressure
sensor is used, and the control indicator
w
illuminates yellow. The tyre pressure dis-
play shows –.–. The tyre pressure is then
monitored by the deflation d etec tion
system, see page 217.
If a comp lete set of wheels w ithout tyre
pressure control system sensors is m ounted
(e.g. four winter tyres), no error m essa ge
will be displa yed. The tyre pressure
monitoring system is not operational. The
tyre p ressure of a set of wheels without
sensors is m onitored by the defla tion
detection system – see pa ge 217.
Sensors for the tyre pressure m onitoring
system can be fitted on request by a
workshop.
When m anually chec king tyre pressure with
a pressure gauge, sc rew the adapter onto
the valve. Tyre pressure – see p age 337.
On each tyre change, the valve inserts and
sealing rings for the tyre pressure
monitoring system must be replac ed b y a
workshop.
The use of commerc ially ava ila ble liquid
filled run-flat systems or repair kits can
impa ir the function of the system.
Vauxhall-approved systems can be used.
Rad io transmitters (e.g. radio headphones,
walk ie-talkies) operated in the area could
cause interference in the tyre pressure
monitoring system.
