Operation
Tyres and wheels
i
The operation of the tyre pressure monitor
can suffer interference if radio transmitting
equipment, e.g. radio headphones, two-way radi-
os, is being operated in or near the vehicle.
i
If you correct the tyre pressure or change
the wheels, this is usually detected automatical-
ly by the tyre pressure monitor. After a few min-
utes of driving, the warning thresholds for the
pressure loss warning are adapted to the new
tyre pressure. A tyre pressure warning is then
cleared automatically.
Reactivating the tyre pressure monitor
All existing warning messages are cleared
and the warning lamp goes out when you
reactivate the tyre pressure monitor. The
current tyre pressures set then become
the reference values used by the monitor-
ing system.
You may reactivate the tyre pressure mon-
itor in the following situations:
앫
After the tyre pressure has been modi-
fied
앫
After a wheel or tyre change

acteristics of the vehicle may otherwise be
affected and you could endanger yourself or
others.
