Recalibration
Settings are made using the centre console's
controls, see MY CAR (p. 114).
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. 81).
3. Select the menu system MY CAR to open
the menus for tyre monitoring.
4.
Select
Calibrate tyre pressure and
press OK.
5. Start and drive the car.
> 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.
The new reference value applies until steps
1-5 are repeated.
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
caps can rust and become difficult to
unscrew.

can be checked, see MY CAR (p. 114).

tyre pressure gauge.

sure in accordance with the tyre pressure
label on the driver's side door pillar
