Wheels and tyres
●
Have the tightening torque of the wheel nuts
checked as soon as possible with a torque
wrench ›››page323. Meanwhile, drive care-
fully.
●
Have the at tyre replaced as quickly as pos-
sible.

Tyre pressure monitor indicator
Fig.198 Instrument cluster: warning of loss
of tyre pressure.
The tyre pressure monitoring system compares
the individual speeds of each wheel and thus
the dynamic radius with the help of the ABS
sensors.
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.198. If only one
tyre is aected, its position on the vehicle will
be indicated.
Loss of pressure: Check left tyre pressure!
Change in wheel diameter
The wheel diameter changes when:
●
Tyre pressure is changed manually.
●
The tyre pressure is insuicient.
●
The tyre's structure is damaged.
●
The vehicle is not level due to 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 has been tted.
●
One wheel has been changed on an axle.
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 replac-
ing one or more wheels, the tyre pressure
monitoring indicator must be recalibrated.
This should also be done, for example, when
switching the front and rear tyres.
It should be calibrated with the vehicle stop-
ped and its tyres cold. If calibrated while the
tyres are hot, the pressure check and calibra-
tion procedure should be repeated when cold
before the next trip.
●
Switch the ignition on.
●
Save the new ination pressure in the info-
tainment system: function button > Ve-
hicle > Exterior > Tyres ›››page35.
●
OR: > Vehicle > Status > Tyres.
After storing the new ination pressure, a con-
rmation message will be displayed, the warn-
ing light in the instrument cluster will ash
briey and a driver alert tone will be played.
The tyre pressure loss indicator uses the ABS
sensors to compare the turns of each wheel
and, therefore, their tread circumferences,
among other aspects. The set values are col-
lected and monitored after a long journey at
dierent speeds.
For example, if the wheels are under very
heavy loads, the tyre pressure must be in-
creased to the total recommended tyre pres-
sure before calibration ›››Fig.198.
