DESCRIPTION
With the key in the ON position and the ring nut in position "O" the daytime lights come on automatically; the other lights and the interior lighting remain off.
|
The automatic switching on of the daytime lights can be activated/deactivated using the Setup Menu in the instrument panel; if the daytime lights are deactivated, none of the lights come on with the ring nut in position O. |
The front daytime lights / side lights are incorporated in the headlamps
The rear side lights are located in the rear side light clusters and also have LED circuits.
With the ignition in the ON position, when the ring nut is turned fowards the dipped headlamps are activated, the daytime lights go out and the side lights, dipped headlamps and number plate lights are turned on.
The side lights warning light in the instrument panel lights up.
The parking lights function makes it possible to switch on the side lights and the no. plate lights with the ignition OFF, to signal the presence of the vehicle whilst it is parked.
With the ignition key in the OFF position or extracted, all the side lights and number plate lights come on when the ring nut is turned forwards. The side lights warning light in the instrument panel lights up.
When the direction indicator lever is activated the lights on one side only (left or right) can be selected.
The function is deactivated by moving the steering column switch unit lights ring nut to the OFF position or at the vehicle Key ON. This last operation resets the function and the Body Computer controls the lights depending on the command selected using the steering column switch unit ring nut.
The follow me home function allows the dipped headlights and the side lights to remain on even after the engine has been switched off (key in OFF position or extracted) for a period of 30 seconds or multiples thereof. The side lights warning light in the instrument panel signals that the lights have remained on.
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.
At the Key-OFF the "Exterior courtesy lights" function switches on the rear side lights and the number plate lights for a limited time when the doors or the tailgate is unlocked using the remote control.
The "Exterior courtesy lights" function can be activated or deactivated using the setup menu in the instrument panel.
The switching on of the side lights is managed by the Body Computer.
The number plate light and numerous other interior lights for lighting the passenger compartment, instruments and controls are activated together with the side lights (these are described and explained in the wiring diagrams for the relevant components), in particular:
Activation and/or deactivation information is sent via the CAN: in this way, the side lights warning light in the instrument panel is also activated. The instrument panel also activates the icon night lighting.
On some versions, the side lights are also activated automatically by the dusk sensor.
This sensor, located on the windscreen under the interior rear view mirror, detects the variations in outside brightness depending on the light setting: the greater the sensitivity, the less external light is required to activate the exterior lights.
The setting of the dusk sensor can be adjusted using the instrument panel setup menu.
When the ring nut is turned in the opposite direction (AUTO position) the side lights and the dipped headlamps automatically come on simultaneously depending on the exterior brightness.
The flashing function is only possible with the sensor activated.
When the command to switch off is given by the sensor, the main beam headlamps are deactivated and then the side lights about 10 seconds later.
The correct operation of the lights is checked by the side lights and no. plate lights check function: the following is checked for each of the circuits:
- open circuit or missing bulb
- short circuit to earth (bulb s.c. or wiring s.c. to earth)
- short circuit to battery voltage (wiring short circuited to Vbatt)
When one of the situations described above is verified, the Body Computer makes the failure status available to the CAN: a special "lights failure" warning light comes on in the instrument panel and, at the same time, the information is shown in the display
