Tread Depth - Vauxhall COMBO Owner's Manual

324 Vehicle care
malfunction or a temporary spare
wheel is used. Once the road tyre has
been refitted, check the tyre pressure
with cold tyres and initialise the
system.
System initialisation
After tyre pressure correction or
wheel change, the system must be
initialised to learn new circumference
reference values:
1. Always ensure that all four tyres
have correct tyre pressure
3 354.
2. Apply parking brake.
3. Initialise the deflation detection
system: If the vehicle has a
graphic info display, press F for
three seconds. If the vehicle has a
colour info display, the
initialisation is done in the vehicle
personalisation 3 107.
4. Reset is confirmed by pop-up
indication.
After initialisation system
automatically calibrates to new tyre
pressures during driving. After longer
drive the system will adopt and
monitor new pressures.
Always check tyre pressure with cold
tyres.
System has to be reinitialised when:
● Tyre pressure has been changed
● Load condition has been
changed
● Wheels have been swapped or
exchanged
The system will not warn
instantaneously on a tyre blow out or
a rapid deflation. This is due to
required calculation time.

Tread depth

Check tread depth at regular
intervals.
For safety reasons, it is
recommended that the tread depth of
the tyres on one axle should not vary
by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
