System limitations

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
the balanced and very gradual pressure
loss that takes place in all four tires
over an extended period of time.

On the other hand, the following situa-
tions can lead to a delayed detection of
pressure loss and even to the system
not functioning:
> Driving on snow-covered or slippery

roads

> Performance-oriented driving: slip at

the drive wheels, high levels of lateral
acceleration

> When driving with snow chains, false

warnings and undetected pressure
losses may occur.

Initializing the system

Each time you correct the pres-
sure in a tire, or change a wheel or

tire, reinitialize the system immediately
afterwards. This requires a bit of driv-
ing.

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

3. Drive off.

It takes a few minutes before the Flat
Tire Monitor can detect a flat tire and
issue a warning.

When driving with snow chains,
do not initialize the system.
