LOCATION OF COMPONENTS ON VEHICLE
1 Front light cluster2 Right tail-light cluster3 Top third brake light4 Left tail-light cluster

FUNCTIONS

The vehicle''s exterior lighting system has been designed with two aims in mind:

  • ensuring maximum efficiency in terms of complying with international regulations which define the illumination specifications of the various components
  • to blend with the design of the vehicle so that the various components enhance the overall image.
In particular, the front light cluster includes the separate function of the side light, dipped headlamp, main beam headlamp, fog light and direction indicators ina single unit.The clear element is made out of one piece of plastic.

PERFORMANCE

The nominal operating voltage for the system can vary from 9 to 16 volts.

STRUCTURE

The front light cluster consists of the following components:

A light unit which includes:

  • A housing for the fog light and the lens cover which focuses the light beam.
  • A housing for the dipped headlamp and the lens cover which focuses the light beam and an internal element for adjusting the light beam geometry to meet standards.
  • A housing for the direction indicator with an orange reflector lens cover.
  • A housing for the main beam headlamp and parabola with mirrored surface.
  • A housing for the side light and the reflector lens cover.
Light beam vertical adjustment device inside the light cluster operated by means of two buttons on the left of the instrument panel.

The following are also present:

  • A fog light bulb 12 Volt - 55 Watt (1)
  • A dipped headlamp bulb 12 Volt - 55 Watt (2)
  • A direction indicator bulb 12 Volt - 5 Watt (3)
  • A main beam headlamp bulb 12 Volt - 55 Watt (4)
  • A side light bulb 12 Volt - 5 Watt

OPERATING PRINCIPLES

The user can operate a ring at the end of the left steering wheel stalk to turn on the side lights, dipped beams and main beams (fixed or flashing position).The same stalk also controls turns signals for lane changes and foglamp/rear foglamp enablement (for further details, see stalk unit 5550A and Body Computer description)

FOLLOW ME HOME FUNCTION

This is a strategy available on the SX trim level which allows the dipped headlamps to remain on, even with the ignition switched off, for a pre-set time.This function is particularly useful, for example, after parking the car in a garage or in poorly lit areas.The function is activated, after the key off, for a maximum of 2 minutes; within this period, pulling the left steering column switch unit lever in the direction of the steering wheel activates the dipped headlamps for 30 seconds; each time the lever is operated, the time increases by a further 30 seconds, up to a maximum of 5 minutes.

Pins

A connection on the light cluster casing controls the side lights, dipped headlamps, main beam headlamps, direction indicators and light beam vertical adjustment

HEADLAMP ALIGNMENT ADJUSTMENT

LOCATION OF HEADLAMP ALIGNMENT ADJUSTMENT COMPONENTS ON VEHICLE
1 Front light cluster2 Light beam adjustment buttons

Operation

The headlamp alignment adjustment device is designed to correctly position the dipped headlamp light beam, in a vertical direction, irrespective of the load on the axles.

Operating methods

It is possible to vary the angle of the light clusters with 4 standard positions by acting on the two switches on the left hand side of the instrument panel.The positions are shown in a special display in the instrument panel.The table below illustrates the three positions which can be selected according to the vehicle load conditions:
Headlamp alignment positionPanorama versionCargo version
-Load statusLoad status
0empty, driver, driver + front passengerempty, driver
relayall seats occupied-
relayall seats occupied + luggage compartment loaded to the maximum technically permissible limit (180 kg)-
3driver + luggage compartment loaded to maximum limit on the rear axle (430 kg)driver + luggage compartment loaded to maximum technically permissible limit and max on the rear axle (550 kg)
The various positions refer to a full fuel tank and an initial vertical adjustment of the light cluster of -1%.

Operating methods

To carry out the headlamp alignment adjustment, proceed as described below:

  • Press button A and keep it pressed until there is an increase by one position (e.g. 0>1, 1>2)
  • Press button B and keep it pressed until there is an increase by one position (e.g. 2>1, 1>0)
The display C will show the positions whilst the adjustment is being made.

STRUCTURE

The right rear light cluster consists of the following components:

  • A light unit which includes:
  • A housing for the side light (1) with a reflector lens cover and brake light.
  • A housing for the direction indicator (3) with a reflector lens cover.
  • A housing for the reversing light (4) with a reflector lens cover.

The left rear light cluster consists of the following components:

  • A light unit which includes:
  • A housing for the side light (1) with a reflector lens cover.
  • A housing for the direction indicator (3) with a reflector lens cover.
  • A housing for the rear fog lamp (4) with a reflector lens cover.
  • A housing for the reversing light
