Tyre pressure monitoring
system
General notes
Applies to: vehicles with tyre pressure monitoring system
The tyre pressure monitoring system keeps a
check on the tyre pressures of the four road
wheels while you are driving.
The system uses sensors to measure tempera­
tures and pressures in the tyres. The sensors
transmit the data to the control unit by radio.
The tyre pressure monitoring system displays the
current pressures and temperatures of the tyres
on the infotainment system while the vehicle is

moving In addition, it compares the
current tyre pressures with the stored tyre pres­
sures and warns you if it detects a discrepancy
qpage 245.
The system cannot check if the stored tyre pres­
sures correspond to the recommended tyre pres­
sures for your vehicle. You must store the new

-after every adjustment to the tyre pressures,
e.g. after changing the laden weight of your ve­
hicle,
-after changing a wheel, or
-when using wheels with new wheel sensors.

WARNING
-The tyre pressure monitoring system helps
the driver to monitor the tyre pressures.
However, it is always the driver's responsibil­
ity to ensure that the tyres are at the correct
pressure.
- Never re-adjust the tyre inflation pressure
when the tyre is hot. This can cause serious
damage to the tyre or even a blow-out,
which could result in an accident.
- Under-inflated tyres flex more than they
should. This causes them to overheat. This
can cause tread separation and tyre blow­
out, which could result in an accident.
- The tyre pressure monitoring system cannot
warn you of tyre damage or defects that
could lead, for example, to a tyre blow-out.
Perform a regular visual check of your tyres.

Note
-The sensors and valves do not have to be de­
tached or changed round when fitting new
tyres. Only the valve core needs to be re­
placed, and if necessary the valve and the
electronic components in the wheel. Please
contact a qualified workshop if you have any
questions.
-After using the tyre repair kit, the tyre pres­
sure monitoring system may malfunction.
Have the sensors renewed by a qualified
workshop.
Displaying tyre pressures and temperatures
Applies to: vehicles with tyre pressure monitoring system
Important: The vehicle must be moving.
► Select the following on the infotainment sys­
I I
tem: MENU button >
pressure loss indicator> Display tyre pres­
sures.
The current tyre pressures are displayed in green,
yellow or red on the infotainment system:
Green:
- The tyre pressure is roughly the same as
the reference value.
Yellow:
- The tyre pressure is too low compared
with the reference value.
Red:
- The tyre pressure is much too low com-
pared with the reference value.
The reference value is the last stored tyre pres­

sure value
Bear in mind that the tyre inflation pressure is al­
so influenced by the temperature of the tyre. The
tyre heats up while the vehicle is being driven and
the tyre pressure will rise accordingly.
