Tire Pressure Monitor (RDC)*

The concept

RDC monitors the tire pressures at all
four wheels, even when the vehicle is
moving. The system provides an alert
whenever the inflation pressure drops
significantly below the specified pres-
sure in one or more tires.

In order for the system to "learn" the
correct tire inflation pressure, check the
inflation pressures in all tires, refer to
the table on page

and make any

necessary corrections. Then activate
the system.

This indicator lamp in the instru-
ment cluster or the Check
Control will inform you if the tire

pressure is not correct.

To switch the system on

1. Turn the ignition key to position 2 (do

not start the engine)

2. Maintain pressure on the button until

the yellow indicator lamp in the
instrument cluster comes on for
several seconds or the message
"SET TIRE PRESSURE" appears in
the Check Control

3. After you have driven for a few

minutes, the RDC will import the
current inflation pressure in the tires
as the reference values which the
system will monitor.

You will only have to repeat this proce-
dure if the tire inflation pressure must
be corrected. Otherwise, the RDC func-
tions automatically when the ignition
key is in position 2, and thus operates
whenever the vehicle is driven.

Loss of tire pressure

If, after a certain period of time, the
inflation pressure has gone down
significantly (which is normal for any
tire), the yellow indicator lamp comes
on or the message "CHECK TIRE
PRESSURE" appears in the Check
Control.

This alerts you that you should have the
tires inflated to the specified pressures
as soon as possible.

If you are prompted to check the
tire pressure shortly after a

correction has been made, this indi-
cates that the corrected values were
not accurate. Please check the inflation
pressure again and make corrections
according to the inflation pressure
table.
