Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the
inflation pressures in your tires as you
drive. The system provides an alert
whenever the inflation pressure drops
significantly in one of the tires.
To initialize the Flat Tire Monitor system
with the correct tire inflation pressures,
start by checking the inflation pressures
in all four tires, comparing them with
the figures specified in the tire inflation
pressure table (page
23 ). Then correct
the tire inflation pressures as neces-
sary. Now you can activate the system.
T he Check Control (refer to page 66 )
will inform you if the tire inflation pres-
sure of one the tires has dropped signif-
icantly.
Activating the system
1. Turn the ignition key to position 2
(do not start the engine)
2. Press the button and maintain pres-
sure until the message "SET TIRE
PRESSURE" appears in the Check
Control (several seconds)
3. As you drive, the Flat Tire Monitor
automatically enters the system ini-
tialization mode in which it stores the
current pressures as its reference
figures. The initialization process
lasts for ten minutes or somewhat
longer. Once it has been completed
the Tire Pressure Monitor is able to
detect and warn of flat tires.

Repeat this process after altering the
tire inflation pressure, changing the tire,
or rotating the wheels.
Do not carry out a new initialization of
the system, if you correct the inflation
pressures to the already specified tire
pressures.
