Flat Tire Monitor - BMW M COUPE 2002 Owner's Manual

Flat Tire Monitor

The concept
The Flat Tire Monitor controls the tire
pressure in all four wheels while driving.
The system is designed to detect when-
ever the inflation pressure in a tire
drops significantly.
The control of the tire inflation pressure
is based on monitoring the speed of the
tires relative to each other. A flat tire
can be detected and reported because
its speed suddenly deviates drastically
from that of the other tires.
Initializing the system
Initializing is necessary to familiarize the
system with the correct inflation pres-
sure.
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement. Do not carry out further
system initialization after correcting the
inflation pressure and letting the system
"learn" what condition is required.
1. Check the tire inflation pressure in all
the tires, comparing them with the
inflation pressure table on page 27,
and adjusting their pressure if neces-
sary
2. Turn the ignition key to position 2
3. Continue to press the button until the
indicator lamp in the instrument
cluster lights up. After a short time,
the indicator lamp will go out auto-
matically
4. Switch the ignition off.
