The two front headlights of the vehicle have the following lights:
The DRL lights (where available) are switched on only by the activation signal with the key at the MAR-ON position. They are not activated by any control on the steering wheel interface lever; their activation is managed by the Body Computer and can be excluded through the special command in the setup menu on the instrument panel. To activate the side lights, turn the special ring nut on the left steering column switch unit stalk. The ring nut only has one position which also activates the dipped beam headlights. The daylight lights are simultaneously deactivated. The two number plate lights and numerous other interior lights for lighting up the passenger compartment, instruments and controls come on together with the side lights. When the side lights and the number plate lights are activated, the six side marker lights, which enable the vehicle to be seen more clearly in poor visibility conditions, also come on. The side marker lights, compulsory for vehicles with maximum dimensions of more than 6 metres, on this version are available for the Long (L) and Extra-long (XL) wheelbase versions. To activate the side lights, turn the special ring nut on the left steering column stalk lever to one of the positions. The side lights activation and/or deactivation information is sent by the Body Computer, via the CAN, to the instrument panel for the management of the "Side lights" warning light. The side lights may be activated automatically by the dusk sensor if it is set to the AUTO function using the ring nut on the left steering column stalk. The dusk sensor is an infrared LED device which detects variations in brightness outside the vehicle depending on the light setting: the greater the sensitivity, the less the exterior light needed to activate the side lights being turned on. The setting can be altered by the user through the instrument panel display set up menu (COMFORT version only). To activate this AUTO function turn the ring nut on the left steering column stalk to the corresponding position. In this way the side lights and the dipped headlights come on automatically depending on the exterior brightness. Once the dusk sensor detects a sufficient level of external light to be able to turn off the lights, it will switch off the dipped beam headlights and, after about ten seconds, the side lights as well.
For safety reasons, the side lights are activated if the inertia switch is operated (FIS). In addition, the vehicle is equipped with a Follow me home function which lights up the area surrounding the vehicle for a limited period. This function can be activated without the key inserted (or with it turned to the OFF position) by pulling the left steering column stalk towards the steering wheel within two minutes of the engine being switched off. This causes the front lights to come on for 30 seconds, a time which can be prolonged by 30 seconds each time the lever is activated, up to a maximum of 210 seconds. When this time is up the lights automatically switch off. When the stalk is operated the side lights warning light in the instrument panel comes on together with the message shown on the display for the period during which the function remains activated. The warning light comes on when the lever is operated and stays on until the function is automatically deactivated. Each movement of the stalk only increases the amount of time the lights stay on. Keep the stalk pulled towards the steering wheel for more than 2 seconds in order to manually interrupt the function. The parking lights function makes it possible to switch on the side lights and the number plate lights with the ignition key turned to STOP or removed, to signal the presence of the vehicle whilst it is parked. If the steering column switch unit left-hand lever is operated (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). The Body Computer manages the correct operation of the DRL, of the side and number plate lights, detecting the following possible faults:
When one of the situations described above occurs, the Body Computer makes the failure status available to the CAN: a special "exterior light failure" warning light comes on in the instrument panel and, at the same time, the information is shown in the display. The system also detects any faults in the rain / dusk sensor: if a fault is detected, the "general failure" warning light in the instrument panel comes on and the information is shown simultaneously in the display. The side marker lights are supplied via a relay switch, managed by the Body Computer, located next to the secondary fuse box and the transformer intake. The side marker lights are protected by a fuse located near the same module. The engagement of the side lights enables the switching on of the fog lights using the special control in the centre panel. |
