Gray wheels
The system cannot detect a flat tire. Reasons
for this may be:
▷ The system is being reset.
▷ Malfunction.
Status information
The status control display additionally shows
the current tire inflation pressures and, de‐
pending on the model, tire temperatures. It
shows the actual values read; they may vary
depending on driving style or weather condi‐
tions.
Resetting the system
Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
Via iDrive and in the vehicle:
1.
"My Vehicle"
2. "Vehicle status"
3. "Tire Pressure Monitor"
4. Switch on drive-ready state and do not
drive off.
5. Reset tire inflation pressure: "Perform
reset".
6. Drive away.
The wheels are displayed in gray and the sta‐
tus "Resetting Tire Pressure Monitor…" is dis‐
played.
After driving faster than 19 mph/30 km/h for a
short period, the set tire inflation pressures are
accepted as reference values. The reset is
completed automatically while driving.
After a successfully completed reset, the
wheels on the Control Display are shown in
green and "Tire Pressure Monitor active. See
label for recommended pressures." is dis‐
played.
You may interrupt this trip at any time. When
you continue the reset resumes automatically.
