Tyre pressure screen
Indication of tire pressures on the basic
screen "Tire pressure"
The basic screen "Tire pressure" shows the cur-
rent actual values of the tire pressures. These val-
ues would be identical to those of a pressure gage
connected to the four valves. These pressures
change while the vehicle is being driven.
– The tire pressures increase as the temperature
in the tires rises, e.g. during high-speed high-
way driving.
– The tire pressures decrease as the tempera-
tures drop, e.g. during trips in cold regions
(such as mountains).
The pressure changes by around 1.5 psi (0.1 bar)
for a temperature change of 50°F (10°C).
The values displayed on the basic screen there-
fore do not allow conclusions to be drawn about
possible pressure deviations.
f
Use only the pressure differences shown in the
TYRE PRESSURE menu or from tire pressure
messages or warnings when correcting the
tire pressure.
Tyre pressure menu (filling information)
Tire pressure menu
MAIN MENU > TYRE PRESSURE
The TYRE PRESSURE menu can only be called up
when the vehicle is stationary.
Deviations in the tire pressures from the required
pressure are shown in the TYRE PRESSURE menu
(filling information). The tire pressure monitoring
system takes this relationship between tire
pressure and temperature into account.
A “–” in front of the value indicates a pressure loss.
f The tire pressures must be adjusted to the
required pressure.
Example : If the tire pressure display shows
“–3 psi (–0.2 bar)”, you must increase the tire
pressure by 3 psi (0.2 bar).
