The spare wheel is not fitted with a
pressure sensor. When the spare wheel is
fitted, the tyre pressure control sy stem will
not operate on this w heel, and the c ontrol
indicator w will light up. The sy stem
rem ains operational for the other three
wheels.
If a complete set of wheels not fitted with
sensors for the tyre pressure control sy stem
is used, e. g. four w heels with winter ty res, or
if retrofitting a different size of tyre, no
fault report will b e display ed. The system
will not be operational. Sensors for the tyre
pressure control sy stem can b e fitted
retrospectively if so desired. We
recom mend that y ou consult a Vauxhall
Authorised Repairer.
