FUNCTIONING

The system includes a dedicated light bulb, located in a special reflector, fitted to the light unit and directed at a 30angle.

(1) : Light unit

(2) : Static directional light (H7)

(3) : Dipped beam (H7)

(4) : Main beam (H7)

(5) : Sidelights (W 5W)

The static directional lights work when the dipped or main beams of the headlights are on.The EDC module (6606) controls the static directional light located on the inside of the bend (corresponding withthe rotating direction of the steering wheel).Activation varies according to 2 main pieces of information:

- Vehicle speed- Steering wheel angle.

The static directional lights will come on when the steering wheel angle is between 25 and 50 and depending onthe vehicle speed. They will switch off when the steering wheel angle is between 15 and 20 and depending on thevehicle speed.

Example:

A driver approaches a right-turn bend at a speed of25 km/h.As soon as the steering wheel angle reaches 35, theEDS module (6606) will turn on the extra lamp in the RHheadlight.

Once out of the bend, as soon as the steering wheelangle goes back below 15, the lamp will switch off.

Remarks:In the event where the direction indicator is activated (whatever the vehicle speed) the static directional light willcome on as of 20 which enables the interior and edges of intersections to be lit more rapidly. The extra lamp willswitch off as soon as the steering wheel angle is below 15.

Finally, it is possible to activate the static directional lights even when stopped. This is very useful when the driveris stopped at a STOP street as the adjacent road may be lit before moving.

The static directional lighting is controlled by a by a PWM (Pulse Width Modulation) signal.

The intensity of the light beam when the static directional lights switch on varies from 80% to 100%:- In 100 m/s if the direction indicator is on- In 10 m/s if the direction indicator is not on.

The intensity of the light beam when the static directional lights switch off varies from 100% to 80% in 860 m/s.

NOTE: Below 80% intensity, the static directional lights switch off.

The static directional lights switch on when:- The dipped or main beams are on- Reverse gear is not engaged- The "Static Directional Headlight" function is activated via the menu on the multi-function screen- The engine running signal is present- The daytime driving lights are deactivated (this may be programmed using the maintenance tool).

DOWNGRADED MODES

The Static Directional Headlight function is deactivated when the following information has been lost for more than2.5 seconds:

- Vehicle speed- Steering wheel angle- Status of the sidelights and indicators.

If the fault fails to appear for more than 5 seconds and the steering wheel has passed through the 0 angle (in-linewith the vehicle axis) the Static Directional Headlight function will be activated once again.

Should a problem occur with the EDS module (6606) or with the communication between the EDS module (6606)and one of the lamps, the function will be deactivated.

If the fault lasts for:- Less than 2.5 seconds, the function is reactivated after the steering wheel passes through the 0 angle in-

line with the axis of the vehicle.- More than 2.5 consecutive seconds, the function is reactivated once the fault has disappeared and at the

next +APC.

BSI1 Built-in Systems Interface:The BSI manages the "Seatbelts Not Fastened Warning" function.It receives "seatbelt fastened" information from the driver and rear passenger switches (4730, 4732, 4733) as wellas the door switches.It commands:

- The appearance of visual warnings on the Instrument Panel (0004) and the Multi-function Screen (7215).- The seatbelt not fastened indicator module (4746) via a LIN link for visual warnings (only with the type A,

C or CT displays).- The audible warning on the CV00 according to the vehicle's speed.

7215 Multi-function screen:The DT-type EMF screen shows the warning messagesand specifies which seatbelts are not fastened.

4746 Seatbelt not fastened warning module:This display (1) is located under the EMF (7215).It informs the occupants of the location of theunfastened seatbelt.

There is no seatbelt not fastened warning module(4746) for the DT multi-function screen. The location ofthe unfastened and detached seatbelts is showndirectly on the screen (controlled by the telematicstransceiver 8480).

6570 Airbag and pretensioner module:This informs the BSI1 of:

- The presence of a front passenger (detection harness 4737)- The fastening status of the front passenger seatbelt (switch 4731).

4730 / 4732 / 4733 / 4734 Front LH, rear LH, rear central rear RH seatbelt fastened switch:These switches inform the BSI1 of the fastening status of each seatbelt by means of a hard-wired link.

4731 Front passenger seatbelt fastened switch:This informs the airbag and pretensioner module (6570) of the fastening status of the seatbelt.

6202, 6207, 6212, 6217 Door switches:These inform the BSI1 of the status of the doors (open or closed).

7800 / 7020 ESP / ABS:This informs the BSI of vehicle speed.

CV00 Steering column switching module:This controls the buzzer for the audible warning.

1660 (BVMP) Electronic Manual Gearbox:This informs the BSI1 that reverse gear has been engaged.

PSF1 (Engine Ancillaries ECU):This acquires reverse gear information (2200) and communicates it to BSI1 if there is a manual gearbox.

FUNCTIONING

The warning on the seatbelt not fastened module (4746):

The warning lights appear on the bar:- In red, if the seatbelt is not fastened- In green, if it is fastened

Comment: If the passenger has not been detected the warning light will remain green even though the seatbelt isnot fastened.

Management of the driver seatbelt:The driver seat is presumed occupied when the ignition is turned on.

The driver's seatbelt not fastened warning light will come on in red if the seatbelt has not been fastened.

Above 20 km/h the driver's seatbelt not-fastened warning light will flash in red. The BSI1 also controls the audiblewarning on the steering column switching module (CV00) which increases in volume for 2 minutes.

After 2 minutes, the warning light stays on but the audible warning stops.

As soon as the seatbelt has been fastened the audible warning stops, the light turns to green and then switches off.

Management of the front passenger seatbelt:A detection harness (4737) is located in the seat cushion, serving to detect the presence of a person. The minimumweight for detection is 35 kg (according to the distribution of the load).

If the passenger is detected and his/her seatbelt has not been fastened, the front seatbelt not fastened warning lightwill come on in red.

Management of the visual and audible warning takes place according to the same principle as for the driver'sseatbelt.

Note: Even if a front passenger has not been detected, this will not affect the functioning of the airbag.


- 15 -

Driver Rear passengers Frontpassengers

Management of the rear seatbelts:Unlike the front passenger seat, the rear seat is not equipped with a detection harness. A warning is given when theseatbelt has been detached and not when it has not been fastened.

Upon ignition, the 3 seatbelt warning lights for the rear will come on and display the fastening status of the seatbelts.

When the seatbelts are fastened the lights come on in green.

Should a seatbelt thereafter be detached:- Below 20 km/h, the warning light for the seatbelt in question comes on in red.- Above 20 km/h, the warning light for the seatbelt in question flashes and the audible warning is emitted

becoming increasingly louder.

The warning on the instrument panel (0004):

The seatbelt not fastened warning (1) on the instrumentpanel comes on if one of the vehicle's seatbelts are notfastened or detached.

The warning light will flash as soon as the vehicle's speedexceeds 20 km/h and one of the seatbelts is not fastenedor detached.

NOTEWORTHY POINTS

- The audible warning stops in reverse gear if the parking radar function is active.- A warning in progress continues to be transmitted if speed drops below 20 km/h.- The seatbelt not fastened warning module switches off:

- Instantaneously as soon as the 5 indicator lights turn green.- After 30 seconds if one of the 3 rear passenger indicator lights remain red (non-detection of

fastening).- The timing of the 30 seconds only starts once the doors have been closed (key in the ignition).- When the passenger airbag is inhibited, beyond a speed of 20 km/h, the passenger seatbelt indicator light

will be permanently displayed in red (without the audible warning) even though there is a passenger present withouthis/her seatbelt fastened.

DOWNGRADED MODES

Should information regarding "vehicle speed" be lost, the warning management system will display thecorresponding warning light permanently in red (without the audible warning).
