COMPOSITION

The vehicle exterior lighting system has been designed and produced with two objectives in mind:

  • guaranteeing maximum efficiency with regard to the international regulations that define the lighting technology specifications for the various components;
  • being integrated with the design of the vehicle so that the various components enhance the image.
In particular the front light cluster incorporates the separate functions of the side light, dipped headlight and main beam headlight in a single unit.

FRONT LIGHT CLUSTER

The unit consists of:
1 - Main beam headlamp2 - Side light3 - Dipped headlamp4 - Direction indicator5 - Headlight vertical axis adjustment screw6 - Headlight horizontal axis adjustment screw7 - Connection8 - Adjustment motorThe front light cluster is a lamp constructed from a fixed lens reflection technology for all the functions (dipped headlight and main beam headlight).It contains special housings where the parabolas and the vertical and horizontal adjustment units with direct systems without idlers are secured. There is an automatic type electrical corrector (electric motor) in the unit for controlling the headlight alignment with an activation control in the instrument panel. The reflective parabolas are made from a metallic thermo-setting material and are covered in a clear paint with a protective function.

LIGHTS OPERATION

SIDE LIGHTS AND NUMBER PLATE LIGHT

The side lights come on when the ring nut on the steering column switch unit left lever is turned to the first position.    Characteristic of working principle 5050 SCREEN WASHERS AND HEADLAMP WASH/WIPEThe switching on of the side lights is managed by the Body Computer: the side lights control function is activated through the enablement signals with the key in the ON position and the command from the steering column switch unit. Activation/deactivation information is sent via the CAN network: in this way, the side lights warning light in the instrument panel is also activated. The instrument panel also activates the nightime lighting.The "parking lights" function is turned on - only with the ignition OFF - by pressing the button in the panel to the left of the steering wheel: engagement is signalled by a roger beep. If the steering column switch unit left lever is turned (in the same way as for activating the direction indicators) it is possible to choose whether to turn on the side lights on both sides of the vehicle (lever in middle position) or only those on one side (lever downwards to select the left side, lever upwards to select the right side).

Dusk sensor

The side lights and the dipped headlamps can be automatically activated using the dusk sensor if the AUTO function in the steering column switch unit is set.The dusk sensor is an infra red device which operates at different sensitivity levels: when the dusk sensor is activated a message is shown on the instrument panel display indicating the sensitivity setting (from 1 to 3): this intensity can be adjusted using the "Mode +" and "Mode -" buttons in the control panel to the left of the steering wheelLocationThe dusk sensor, integrated with the rain sensor, described below, is located on the windscreen, just below the rear view mirror.

Follow me home

The "Follow me home" function allows the dipped headlamps and the side lights to remain on even after the engine has been switched off (key in OFF position) for a period of 30 seconds or multiples thereof. It is turned on using the lever in the same way as for activating the flasher within 2 minutes of the ignition being switched OFF: each time the lever is operated, the period for which the lights are on is increased by 30 seconds to a maximum of 210 seconds. The function is excluded if the ignition is turned ON or if the flasher lever is operated for more than 2 seconds.

DIPPED BEAMS

The vehicle is equipped with two dipped beams in the headlamps.The dipped beams are activated by turning a wheel on the stalk switch to the next position after the side light setting.A special relay - managed by the Body Computer - controls the engagement of the dipped headlamps using the enablement signals with the ignition ON and the specific steering column switch unit command signal.With the dipped headlamps on, the simultaneous presence of the main beam and fog lights commands disables the dipped headlamps. The subsequent deactivation of one of these two commands, with the dipped headlamps control still on, means that the dipped headlamps will be turned back on again.

MAIN BEAMS

The vehicle is equipped with two main in the headlamps.

The main beams are switched on by the steering column switch unit:

  • with the dipped beams on, by pushing the lever towards the dashboard (stable mode)
  • in flashing mode, by pulling the lever toward the steering wheel (unstable mode)
A special relay - managed by the Body Computer - controls the engagement of the dipped headlamps using the enablement signals with the ignition ON and the specific steering column switch unit command signal. Activation/deactivation information is sent via the CAN network: in this way, the main beam warning light is activated in the instrument panel.
for legal reasons, if the dusk sensor is activated, only the flasher can be operated and the main beams cannot be turned on permanently; the AUTO function must be switched off in order to activate these lights.

DIRECTION INDICATORS/HAZARD WARNING LIGHTS

The left and right direction indicators are switched on by raising or lowering the special lever on the left of the steering column switch unit; the function is activated with the ignition key in the ON position.The hazard warning lights (left and right direction indicators operated simultaneously) are activated via a button in the centre of the dashboard amongst the climate control system controls and all the direction indicators are activated at the same time. An LED at the back of the control button also comes on synchronized with the flashing of the exterior lights; this function is always activated.The engagement of the direction indicators / hazard warning lights is managed by the Body Computer which also controls the flashing frequency which is sent to the other nodes via the CAN serial network. In this way the two direction indicator warning lights in the instrument panel are also switched on; in addition, the system provides a low frequency acoustic signal in conjunction with the activation of the lights.

BRAKE LIGHTS

The vehicle brake lights are located at the rear in the side light clusters and in the special central third brake light.They are operated each time the brake pedal is pressed via the special switch on the actual pedal.The switch fitted on the pedals consists of two contacts which supply two signals: the first is the N.A. type and recognizes the position of the brake pedal if it is not in the rest postion, i.e. the pedal is pressed; the second is the N.C. type and recognizes the position of the brake pedal in the rest position.The lights are turned on by the N.A. contact (pedal pressed). The N.A. switch information is sent, in particular, to the engine management control unit and to the ABS control unit, whilst the N.C. switch information aids the engine management control unti, especially for the Cruise Control function.

REVERSING LIGHTS

The vehicle has two reversing lights located in the rear light clusters, which are activated each time reverse gear is engaged via the special switch located on the outside of the gearbox casing.The signal that reverse gear has been engaged is managed by the Body Computer which forwards this information to the steering column switch unit as well for the automatic operation of the rearscreen wiper and to the parking sensors control unit

FOG LIGHTS

The vehicle is equipped with two additional fog lamps located in the front bumper activated via the special button in the controls to the left of the steering wheel; when the lights are on, the warning light in the instrument panel comes on.

A special relay - managed by the Body Computer - controls the engagement of the fog lights: relay excitation is activated with:

  • enablement signal with key in ON position
  • control signal coming from the switch
  • side lights on signal.
If the side lights are turned off, the fog lamps are deactivated even if the operating button is still pressed. When the side lights are switched on again, the fog lights do not come on automatically, but only when the button is pressed again. If the key is switched off (OFF position) and then switched back to the MAR (ON) position M, the button must be activated again to turn on the fog lights.

REAR FOGLAMPS

The vehicle is equipped with two bright rear fog lamps located in the rear light clusters, activated via the special button in the controls to the left of the steering wheel; when the lights are on, the warning light in the instrument panel comes on.

The switching on of the rear fog lamp is managed by the Body Computer: it is activated by:

  • enablement signal with key in ON position (INT);
  • control signal coming from the switch;
  • dipped headlamps or fog lights on signal.
If the dipped headlamps lights or the fog lights are turned off, the rear fog lamps are deactivated even if the operating button is still pressed. When the lights are turned on again, the rear fog lamps do not come on automatically, but only if the button is pressed again. If the ignition is switched OFF and then turned ON, the operating button must be pressed again to switch the rear fog lamps on.
