Tire Pressure Warning (RDW)
Flat tire
In the event of a flat tire, the message
"TIRE DEFECT" appears in the Check
Control. In addition, a gong is sounded.
If this occurs, reduce vehicle speed
immediately and stop the vehicle in a
safe location. Avoid hard brake applica-
tions. Do not oversteer. Correct the tire
failure using the M Mobility system
(refer to page 162).
The RDW cannot inform you of
sudden and severe tire damage
caused by external influences.
The RDW will not identify the natural,
even loss of pressure in all four tires,
either.
<
Check the tire inflation pressure
on a regular basis and correct if
necessary. Refer to page 26.
Do not carry out any kind of system
activation when using snow chains.
Under these kinds of conditions, false
warnings and unidentified losses in
pressure are possible.
In certain circumstances, when driving
on snow-covered or slippery road
surfaces, there may be a delay in identi-
fying any loss in inflation pressure.
A sporty driving style (slip at the wheels
receiving the torque, high lateral accel-
erations) can lead to delayed RDW
warnings.

System fault
The message "TIRECONTROL
INACTIVE" appears in the Check
Control if there is a system fault.
Please contact your BMW center for
additional information.
