Tire Pressure Monitor (TPM)*

The concept

TPM monitors the tire pressures at all
four tires even while the vehicle is mov-
ing. The system provides an alert when-
ever the inflation pressure drops signifi-
cantly below the specified pressure in
one or more tires.

This indicator lamp in the instru-
ment cluster informs you when
the tire pressure deviates from

the target values.

Initializing the system

Initializing is necessary to familiarize the
system with the correct inflation pres-
sures.

Repeat this process after tire replace-
ment, tire rotation or any changes in tire
inflation pressure.

1. Check the tire inflation pressures in

all the tires, comparing them with the
inflation pressure chart on page

and adjusting their pressure if neces-
sary

2. Turn ignition key to position 2, do not

start the engine

3. Press the button long enough for the

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

4. After a few minutes' driving time,

TPM sets the current inflation pres-
sures in the tires as the target values
to be monitored.

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 cor-

rection has been made, this indicates
that the corrected values were not
valid. Please check the inflation pres-
sure again and make corrections
according to the inflation pressure
table. Then reinitialize the system.

Flat tire

If there is a tire failure with loss of pres-
sure, a red light will appear in the indi-
cator lamp. This visual alert is accom-
panied by an acoustic warning signal.
