• Tire pressure must only be adjusted wh en the temperature of the
tires is about the same as ambient air temperature.
• The yellow symbol disappears, when the tire pressure is
corrected and the new pressure is stored in the system~ page

• After changing a wheel you have to adjust the tire pressures on
a ll whee ls . In addi tion , you must then initialize the new tire pres­
sures in the tire pressure mon itoring system ~ page
