Tire Pressure Monitor (RDC)

The concept

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

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

and make corrections as

necessary. Then activate the system.

This indicator lamp in the instru-
ment cluster will inform you if
the tire pressure is not correct.

To activate the system

1. Turn ignition key to position 2 (do not

start the engine)

2. Press the button long enough for the

yellow indicator lamp in the instru-
ment cluster to light up for a few
seconds

3. After a few minutes driving time, the

RDC adopts the current pressure
levels as the reference, and from that
point on, can detect and report a flat
tire.

You will only have to repeat this proce-
dure following a correction of the tire
inflation pressure. Otherwise, RDC
functions automatically when the igni-
tion key is in position 2, and thus oper-
ates whenever the vehicle is driven.

In the event of loss in inflation
pressure

If the inflation pressure has dropped
significantly over a long period of time
(which is normal for any tire), the yellow
indicator lamp will come on.

This alerts you to 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. Then activate the system once
again.
