This symbol will appear in the
Check Control panel to inform you
when the inflation pressure varies
from that stored in the system. A text
message appears at the same time. Please
take note of the additional information in
the Control Display panel.
You can find more information on the
Check Control starting on page 80.
The RDC cannot alert you to severe
and sudden tire damage caused by
external factors.<
To initialize the system 1.With the vehicle parked, switch on the
ignition
2.Select "RDC" from the "Settings" menu
and confirm your selection. The initializa-
tion menu appears. "INITIALIZE" 1.Select and confirm
2.RDC is initialized. A message appears in
the Check Control panel
3.After several minutes of driving RDC will
adopt the tires' current inflation pressures
as its references.
The current data appear in the Control
Display. These figures are more accurate than those that appear on the inflation
gauges at filling stations, etc.
The only time you will need to repeat this
procedure is after correcting your tire pres-
sures. Because RDC automatically
assumes operation each time you switch
on the ignition, it is on duty whenever you
drive.
If the system detects a flat tire during
the initialization process, the tires in
the Control Display will appear in red.<
Do not start initialization
Select and confirm to return to the
"Settings" menu.
Status indicators in the Control
Display The status of the system is indicated by the
color of the tires. GreenTire inflation pressures correspond to the
initialized level.YellowThe inflation pressures in the tires have
fallen to below the specified level, which is
normal in every tire after a certain amount
of time.
This alerts you to have the tires inflated to
the specified pressures as soon as
possible. RedPressure loss in indicated tire.
If this occurs, reduce vehicle speed imme-
diately and stop the vehicle. Avoid hard
and sudden steering and braking maneu-
vers. BlackThe system is being initialized.
The system needs several minutes to
complete the initialization process, after
which it is ready to detect and report tire
problems.

driver's and passenger sides.
Your settings appear in the
Control Display's status line.
The figures in the display provide a general
indication of interior temperature. When
you start the vehicle, this system ensures
that the selected temperature is achieved
as quickly as possible. It then maintains
this temperature, regardless of the season.
Defrost windows and clear them of
condensation
This program quickly removes
ice and condensation from the
windshield and door windows.
To adjust air supply manually
You can adjust the air supply by
turning. The automatic air
supply control is operational
whenever you see your selec-
tion represented by a bar in the
Control Display's status line. The automatic
air distribution remains in operation as
before. You can reactivate the automatic
air supply mode with the AUTO button.
Air conditioner operation
The air conditioner cools and
dehumidifies the incoming air
before also reheating it as
required, according to temperature setting.
Depending on the weather, the windshield
may fog over briefly when the engine is
started.
The air conditioner comes on automatically
when you select the AUTO program.
Maximum cooling
Select this program to obtain
maximum cooling as quickly as
possible.
The temperature display reverts
to 61 7 (16 6) while the system switches
to the recirculated-air mode and starts to
provide maximum air supply through the instrument panel outlets only. For this
reason you should ensure that these
outlets are open before selecting this
program.
Outside air/AUC Automatic recircu-
lated-air control/Recirculated air
You can respond to unpleasant
odors or pollutants in the imme-
diate environment by tempo-
rarily suspending the flow of outside air.
The system then recirculates the air
currently within the vehicle. AUC executes
this function automatically.
Press the button repeatedly to run through
the following control sequence:
>Indicator lamps off: outside air flows into
the vehicle
>Left-hand indicator lamp on Ð AUC
mode: the system detects pollutants in the
outside air and responds by deactivating
the outside air supply when required. The
system then recirculates the air currently
within the vehicle.
Depending upon air quality, in the auto-
matic mode the system may start to alter-
nate between its outside-air and
recirculated-air modes
>Right-hand indicator lamp on Ð Recircu-
lated-air mode: the supply of outside air
into the vehicle is permanently blocked.
The system then recirculates the air
currently within the vehicle.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
should switch it off while also increasing air
supply as required.<
Residual heat mode
The system uses the warmth
stored in the engine to heat the
interior when the ignition is off,
for instance, while the vehicle is
stopped at a school to pick up a
child.
You can adjust the automatic climate
control's settings when the ignition lock is
in the radio mode. The system blows
