pressure with cold tyres and initialise the
system.
CAUTION
Deflation detection system warns just
about low tyre pressure condition
and does not replace regular tyre
maintenance by the driver.
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
ð page 167.
2. Apply parking brake.
3. Initialise the system via the Info ð
page 68.
4. Reset is confirmed by pop-up
indication.
After initialisation system automatically
calibrates to new tyre pressures during
driving. After longer driving 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.
