TyRE PRESSURE MONITOR (1/3)
If the vehicle is equipped with the func-
tion, this system monitors the tyre pres-
sure.
The tyre pressure can be adjusted
when cold (refer to the information on
“Tyre pressures”).
If tyre pressures cannot be checked
when the tyres are cold, the recom-
mended pressures must be increased
by 0.2 to 0.3 bar (3 PSI).

Operating principle
Each wheel (except for the emergency
spare wheel) has a sensor in the infla-
tion valve which periodically measures
the tyre pressure.
Never deflate a hot tyre.

Changing a wheel
The system informs the driver via the
display 1 and trip computer and warn-
ing system 2 that the tyres are suf-
ficiently inflated and warns if they are
underinflated or leaking.
If you wish to change your wheels (fit-
ting winter tyres etc.), the system will
reset itself automatically after approx-
imately two minutes driving at a mini-
mum speed of 12 mph (20 km/h).
This system monitors the tyre pressure.
Depending on the vehicle, the infor-
mation is displayed on the instrument
panel. In this case, they appear:
– with the ignition on, when scrolling
through the trip computer and warn-
ing system information by pressing
control 3 (refer to the information
on the “trip computer and warning
system” in Section 1);
This function is an addi-
tional driving aid.
However, the function does
not take the place of the
driver. It cannot, therefore, under
any circumstances replace the vig-
ilance or the responsibility of the
driver.
Changing a wheel
The system may take sev-
eral minutes depending on
use for the new wheel po-
sitions and pressures to be recog-
nised; check the tyre pressures after
all operations.
– or if there is a fault when driving
(refer to the following pages to find
out more about the warning mes-
sages).
Check the tyre pressures, including
the emergency spare wheel, once a
month.
