Tread Depth - Opel 2015 Combo Owner's Manual

If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for getting
low pressure. Check tyre pressure.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w flashes for
several seconds then illuminates
continuously.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. TPMS is not operational for
these wheels. For the further three
wheels, TPMS remains operational.

on version) a corresponding message
appears at each ignition cycle until
the tyres are inflated to the correct
tyre pressure.

Temperature dependency
Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Therefore it is
important to check tyre pressure with
cold tyres.
General information
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved tyre repair kits can be used.
Tyre repair kit 3 149.
External high-power radio equipment
could disrupt the TPMS.
Each time the tyres are replaced,
TPMS sensors must be dismounted
and serviced by a workshop.
Relearn function
After changing wheels, TPMS needs
to recalculate. The relearn process
takes up to 20 minutes of driving with
a minimum speed of 24 km/h.
If problems occur during the relearn
process, control indicator w flashes
for several seconds then illuminates
Vehicle care
continuously and (depending on
version) a warning message is
displayed in the Driver Information
Centre.

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).
For safety reasons, it is
recommended that the tread depth of
the tyres on one axle should not vary
by more than 2 mm.
