Operation Manual

227Driving and operation
Some brands of tyres have a beaded edge
for alloy wheels to protect against
damage. If wheel trim is used on steel
wheels with beaded-edge tyres, the
following specification must be followed:
z Use of wheel trims and tyres that
approved by Vauxhall for the vehicle in
question and thereby fulfil all
requirements for the wheel and tyre
combination.
z If the wheel trims and tyres used are not
Vauxhall-approved, the tyres must not
have a beaded edge.
Tyre pressure
Check tyre pressure, including the spare
wheel, at least every 14 days and prior to
any long journey; the tyres should be
checked when cold. Don’t forget to check
the spare 3.
Use the valve cap key to make unscrewing
the valve caps easier. The key is located on
the inside of the tank flap.
In vehicles with tyre pressure monitoring
system 3 there is an adapter in the valve
cap key. Screw adapter to valve before
attaching tyre pressure gauge, see
page 219.
Tyre pressure, see page 337 and the
adhesive foil 3 on the inside of the tank
flap. Have adhesive foil replaced after
changing to different tyre size.
Do not reduce tyre pressure when the tyres
are warm. Otherwise the pressure may
drop below the permissible minimum when
the tyres cool down.
9 Warning
Use of unsuitable tyres or wheel trims
could lead to sudden loss of air and
thereby accidents.
