5. Select Calibrate tyre pressure. Press
OK to confirm that the tyre pressure in all
tyres has been checked and adjusted.
Calibration will then start.

Incorrect tyre pressure may lead to
tyre failure, which could result in the

The system cannot indicate sudden
tyre damage in advance.

> Recalibration is carried out while the
car is being driven and can be inter-
rupted at any time. If the engine is
switched off while recalibration is in
progress then it is resumed when the
car is driven again. The system pro-
vides no confirmation when the cali-
bration is complete.
TM calibration
Deleting the messages
1. Check the tyre pressure in all tyres with a
tyre pressure gauge.
In order for TM system to work correctly, a
reference value for the tyre pressure must be
determined. This must be done each time the
tyres are changed or the tyre pressure is
changed by recalibrating the system in MY
CAR.
2. Inflate the tyre/tyres to the correct pres-
sure in accordance with the tyre pressure
label on the driver's side door pillar
(between front and rear doors).
The new reference value applies until steps
1-5 are repeated.
For example, the tyre pressure should be
adjusted when driving with a heavy load or for
high-speed driving (above 160 km/h
(100 mph)). Following which, the system must
be recalibrated.
3. Recalibrate the TM system in MY CAR.
NOTE
NOTE
To avoid incorrect tyre pressure, the pres-
sure should be checked on cold tyres.
"Cold tyres" means the tyres are the same
temperature as the ambient temperature
(approx. 3 hours after the car has been
driven). After a few kilometres of driving,
the tyres warm up and the pressure
increases.
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.
Recalibration
Settings are made using the centre console's
controls, see MY CAR (p. 119).
1. Switch off the ignition.
2. Inflate all tyres to the desired pressure in
accordance with the tyre pressure label
on the driver's side door pillar (between
front and rear doors) and select key posi-
tion II, see Key positions - functions at
different levels (p. 84).
NOTE
After a tyre has been inflated, always
refit the dust cap in order to avoid
