Flat Tire Monitor*

The concept
System limitations
As you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires. The system alerts you whenever
the inflation pressure of a tire falls sig-
The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors and does not detect
nificantly below the pressure of another the balanced and very gradual pressure
tire.
loss that takes place in all four tires
over an extended period of time.<
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.
On the other hand, the following situa-
tions can lead to a delayed detection of
pressure loss and even to the system
not functioning:
Initializing the system
>
Driving on snow-covered or slippery
roads
Performance-oriented driving: slip at
the drive wheels, high levels of lateral afterwards. This requires a bit of driv-
acceleration
When driving with snow chains, false
warnings and undetected pressure
losses may occur
When driving with a space-saver
spare tire, the Flat Tire Monitor can-
not function.
Each time you correct the pres-
sure in a tire, or change a wheel or
tire, reinitialize the system immediately
Functional requirements
>
In order for the Flat Tire Monitor to learn
the correct tire inflation pressure,
please do the following:
ing.<
>
>
1.
Check the tire inflation pressures in
all tires
1. Before driving off, start the engine
but do not start driving
2. Press the button as long as you need
to until the yellow indicator lamp in
the instrument cluster lights up for a
few seconds
2.
Compare them with the tire inflation
pressure table on page 26 and cor-
rect them, if necessary
3.
Initialize the system.
3.
Drive off.
It takes a few minutes before the Flat
Tire Monitor can detect a flat tire and
issue a warning.
