Vehicle care181After adjusting tyre pressure initialise
system to extinguish the control
indicator and restart system.
If the failure continues to be
displayed, contact a workshop. The
system is inoperable when ABS or
ESC has a malfunction or a
temporary spare wheel is used. Once
the tyre has been refitted, check the
tyre 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 pressure3 210.
2. Apply parking brake. 3. Initialise the system via the Info Display 3 75.
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.
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.
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
