Wheels and tyres
304
If the rolling circumference of one or more
wheels has changed, the tyre pressure moni-
toring indicator will indicate this on the instru-
ment panel through a warning lamp and a
warning to the driver ››› Fig. 203. When only
one specic tyre is aected, its position within
the vehicle will be indicated.
Loss of pressure: Check left tyre
pressure!
Wheel tread change
The wheel diameter changes when:
•
Tyre pressure is changed manually.
•
Tyre pressure is insuicient.
•
The tyre structure is damaged.
•
The vehicle is unbalanced because of a load.
•
The wheels on an axle are subject to a heav-
ier load (e.g. with a heavy load).
•
The vehicle is tted with snow chains.
•
The temporary spare wheel is tted.
•
The wheel on one axle is changed.
There may be a delay in the reaction of the tyre
pressure monitoring indicator or it may not
indicate anything under certain circumstances
(e.g. sporty driving, snow-covered or unpaved
roads, or when driving with snow chains).
Calibrate the tyre pressure monitoring indi-
cator
After changing the tyre pressure or replacing
one or more wheels, the tyre pressure moni-
toring indicator must be recalibrated. Do the
same, for example, when the front and rear
wheels are swapped.
•
Switch the ignition on.
•
Memorise the new ination pressure in the
Infotainment system: function button >
Vehicle info > Vehicle status ››› page 35.
•
OR: through the
Service
menu on the in-
strument cluster
›››
page 31.
When driving, the system self-calibrates the
tyre pressure provided by the driver and the
wheels tted. After a long journey with varied
speeds the programmed values are collected
and monitored.
With the wheels under very heavy loads, the
tyre pressure must be increased to the total
recommended tyre pressure before the cali-
bration
›››
Fig. 203.
WARNING
When the tyres are inated at dierent pres-
sures or at a pressure that is too low then a
tyre may be damaged resulting in a loss of
control of the vehicle and a serious or fatal
accident.
•
If the lamp lights up, reduce speed im-
mediately and avoid any sudden turning or
braking manoeuvres. Stop when possible,
and check the tyre pressure and status.
•
The tyre pressure monitoring system can
only operate correctly if all of the tyres are
inated to the correct pressure when cold.
•
If a tyre has not been punctured and it does
not have to be changed immediately, drive to
the nearest specialised workshop at a mod-
erate speed and have the tyre checked and
inated to the correct pressure.
