Flat Tire Monitor - BMW SERIE 3 COUPE 2002 Owner's Manual

Flat Tire Monitor

*
The concept
As you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires in order to detect and warn of any
substantial pressure loss.
The system actually detects pressure
loss by monitoring differences in the
relative speeds of the four wheels. It
interprets variations outside specified
limits as severe pressure loss, and then
responds by generating a warning.
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 adjusting the
inflation pressure and letting the system
"learn" the correct pressures.
1. Check the tire inflation pressures in
all the tires, comparing them with the
inflation pressure chart on page
and adjusting their pressure if neces-
sary
2. Turn the ignition key to position 2
3. Press the button as long as you need
to until the indicator lamp on the
instrument cluster lights up. After a
little while, the indicator lamp will go
out by itself
4. After a few minutes driving time, the
Flat Tire Monitor adopts the current
pressure levels as the reference, and
from that point on, can detect and
report a flat tire.
