Tyre pressure indicator: calibrating
Note
♦ The calibration of the Tyre Pressure Loss Indicator must on‐
ly be performed “after” the tyre pressure has been corrected
to the prescribed values.
♦ If no pressure loss and tyre damage are found after a tyre
pressure warning, the incorrect warning can be rectified by
calibrating.
Tyre Pressure Loss Indicator compares the speed and thus
the rolling circumference and vibrations of the individual wheels
via the ABS sensors. If the tyre pressure changes on one or
several wheels, the Tyre Pressure Loss Indicator will indicate
this in the dash panel insert and the Infotainment system.
The rolling circumference of tyre changes if:
♦ The tyre pressure is too low.
♦ The tyre has structural damage.
♦ The vehicle is loaded more heavily on one side.
♦ The wheels on one axle are loaded more heavily (e.g. when
towing a trailer or when driving in mountains).
♦ Snow chains are fitted.
♦ The temporary spare wheel is fitted.
♦ One wheel per axle has been changed.
The tyre pressure monitoring warning lamp has a yellow warn‐
ing lamp in the dash panel insert -arrow-.
♦ A “PERMANENT LIGHTING-UP” in conjunction with a warn‐
ing tone, means “WARNING”, pressure loss has been detec‐
ted, check tyre pressure and carry out calibration.
Calibration:
– Switch on ignition.
– Switch on Infotainment system.
