BMW 7 Series: Tire pressure monitor- Tire conditions
General information
Tire and system status are indicated by the color of the wheels and a SMS text message on the Control Display.
Any existing messages may not be deleted if the displayed target pressure is not reached after the tire inflation pressure is corrected.
All wheels green
- The system is active and bases warnings on the displayed target pressures.
- For tires with special approval: the system is active and bases warnings on the tire inflation pressures stored during the last reset.
One to four yellow wheels
A flat tire or major drop in the tire inflation pressure has occurred in the indicated tires.
Gray wheels
It may not be possible to identify tire inflation pressure losses.
Possible causes:
- Malfunction.
- During tire inflation pressure measurement, after confirmation of the tire settings.
- For tires with special approval: a reset is performed for the system.
For tires with special approval: perform a reset
Via iDrive:
- "CAR"
- "Vehicle status"
- "Tire Pressure Monitor"
- Make sure that correct tire settings have been made.
Tire settings
- Switch on drive-ready state and do not drive off.
- Reset tire inflation pressure: "Perform reset".
- Drive away.
The wheels are displayed in gray and the following is displayed "Resetting tire pressure...".
After a travel time of several minutes, the set tire inflation pressures are accepted as the target tire inflation pressures. The reset is completed automatically while driving.
After a successfully completed reset, the wheels on the Control Display are shown in green and the following is displayed: "Reset successful." You may interrupt this trip at any time. When you continue the reset resumes automatically.
Messages: for tires without special approval
General information
low tire inflation pressure may cause the DSC Dynamic Stability Control to be switched on.
Safety information
Warning
A damaged regular tire with low or missing tire inflation pressure impacts handling, such as steering and braking response. Run-flat tires can maintain limited stability. There is a risk of accident. Do not continue driving if the vehicle is equipped with normal tires. Follow the information on run-flat tires and continued driving with these tires.
If a tire inflation pressure check is required
Message
A symbol with a Check Control message appears on the Control Display.

Inflation was not carried out
according
to specifications, e.g., the tire has
not been sufficiently inflated.
The system has detected a wheel change, but no reset was done.
The tire inflation pressure has fallen below the level of the last reset.
No reset was performed for the system.
The system issues a warning based on the tire inflation pressures stored during the last reset.
Measure
- Check the tire pressure and correct as needed.
- Perform a system reset.
If the tire inflation pressure is too low
Message
A yellow warning light is
illuminated in
the instrument cluster.
In addition, a symbol with a Check Control message appears on the Control Display.
There is a tire inflation
pressure loss.
No reset was performed for the system.
The system issues a warning based on the tire inflation pressures stored during the last reset.
Measure
- Reduce the vehicle speed. Do not exceed a speed of 80 mph/130 km/h.
- At the next opportunity, for instance at a gas station, check the tire inflation pressure in all four tires and correct if necessary.
- Reset the system
If there is a significant loss of tire inflation pressure
Message
A yellow warning light is
illuminated in
the instrument cluster.
In addition, a symbol with the affected tire appears in a Check Control message on the Control Display.

There is a flat tire or a major
loss in
tire inflation pressure.
No reset was performed for the system.
The system issues a warning based on the tire inflation pressures stored during the last reset.
Measure
- Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneuvers.
- Check whether the vehicle is fitted with normal
tires or run-flat tires.
Run-flat tires are labeled with a circular symbol containing the letters RSC marked on the tire's sidewall.
Run-flat tires
- Read the description on What to do in case of
a flat tire.

Temperature
The tire inflation pressure depends on the tire's
temperature.
Driving or exposure to the sun will increase the
tire's temperature, thus increasing the tire inflation
pressure.
