TM is then recalibrated and the new reference
value applies until steps 1-5 are carried out
again.

NOTE
Remember that the TM system must be
recalibrated at each tyre change or if the
tyre pressure is changed. If new reference
values are not stored then the system can-
not function properly.
NOTE
•
After a tyre has been inflated, always
refit the dust cap in order to avoid
damage to the valve from gravel, dirt,
etc.
•
Only use plastic dust caps. Metal dust
and
caps can rust and become difficult to
unscrew.
