Flat Tire Monitor
*
Activate/deactivate the systemThe Flat Tire Monitor automatically
assumes operation whenever you turn
the ignition key to position 2. Unless
manually deactivated, it is always on
during normal vehicle operation.
To deactivate the system: press the
button, the yellow indicator lamp comes
on.
To activate the system: press the
button again, the indicator lamp goes
out.
You should deactivate the system
before driving with snow chains, as the
chains can generate spurious warnings
and/or prevent the system from
detecting actual pressure loss.
In the event of a flat tire
The red warning lamp in the
instrument cluster lights up to
warn of pressure loss and tire
failure. This visual alert is accompanied
by an acoustic warning signal. Reduce
your speed immediately, and steer and
brake gently as you bring the vehicle to
a stop.
To reset the warning lamp: after
replacing the flat tire you will need to
reset the red warning lamp manually:
maintain pressure on the Flat Tire
Monitor button until the warning lamp
goes out. Then reinitialize the system.
The Flat Tire Monitor cannot
provide you with advance warning
of sudden and severe tire damage
caused by external factors.
The system also does not detect the
gradual and minor loss of pressure that
all tires display over extended periods
of time.<
Check the tire inflation pressures
on a regular basis, correcting
them as necessary, refer to page 24.
The system may respond to operation
on slippery or snow-covered road
surfaces with false warnings or delays
in detecting actual pressure loss.
Performance-oriented driving (slip at
the drive wheels, high rates of lateral
acceleration) can also increase the time
that the Flat Tire Monitor requires to
detect a flat tire.<
System malfunctionsThe yellow indicator lamp in the instru-
ment cluster lights up and remains on
until the problem is corrected.
Please refer the problem to your BMW
center.
