Tread Depth - Vauxhall Zafira 2014 Owner's Manual

Each time the tyres are replaced, the
tyre pressure monitoring system
sensors have to be dismounted and
serviced. For the screwed sensor
replace the valve core and sealing
ring, for the clipped sensor replace
complete rubber valve stem.
Auto learn function
After changing wheels the vehicle
must be stationary for approx.
20 minutes, before the system
recalculates. The following relearn
process takes up to 10 minutes of
driving with a minimum speed of
16 mph. ---- can be displayed in the
Info-display or pressure values can
swap.
If problems occur during the relearn
process, w will flash and then
illuminate continously.
Temperature dependency
Cold tyres decrease the tyre
pressure, warm tyres increase the
tyre pressure. During driving tyre
temperature and pressure increase.
The displayed tyre pressure value
shows the actual tyre pressure.
Therefore it is important to check tyre
pressure with cold tyres.
System initialisation
After a wheel change or tyre pressure
adjustment, the system must be
initialised: inflate the cold tyres to the
prescribed pressure according to the
tyre information label or this
Vehicle care
document 3 207. Then switch on
ignition and press and hold the DDS
button for approx. 4 seconds. w
flashes three times.
If the tyre pressure difference
between the left and the right wheel
on one axle is more than 30 kPa, tyre
pressure monitoring system
malfunction will be indicated, as the
vehicle starts moving for the first time
after initialisation. Adjust the tyre
pressure and repeat initialisation.
Note
The system needs to be initialised
after tyre pressure change,
otherwise it will not be able to warn
properly.

Tread depth

Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
