GENERAL DESCRIPTION
In all conditions the numerous sources of light fitted provide good lighting in the interior of the passenger compartment and/or of some specific points.
The front ceiling lamp F3 and rear ceiling lamp F2 turn on automatically when opening the doors: these two ceiling lamps are timed: they both turn on when one of the four doors is opened for 100 + 200 seconds; after closing the doors they stay on for about another 15 seconds; they can be turned off when the key is turned to MAR.
Both ceiling lights can obviously be turned on manually by means of the switch located on them.
There is also a spotlight on the support of the front ceiling light F3, which allows reading, for example, without disturbing the driver.
NOTE: This ceiling light system is different for the versions with convertible top and anti-theft system. However, everything is the same regarding the operation indicated here.
- Volumetric anti-theft sensor (see "Anti-theft")
- I.R. anti-theft receiver (see "Anti-theft ")
- Volumetric anti-theft sensor (see "Anti-theft")
- Sunroof control switch (see "Sunroof")

FUNCTIONAL DESCRIPTION
A special service light F5 illuminates the baggage compartment, controlled by opening of the boot. This light is also timed (for about 20 minutes), which prevents the battery from discharging if the boot is unintentionally left open.
Service light F3 receives power directly from the battery through fuse F16 of fuse box G1: this allows the reading spotlight to be turned on by means of its own switch or the ceiling light by means of its own switch.
The switch has three positions:
- – ceiling light always off
- – ceiling light controlled by opening/closing the doors
- – ceiling light turned on manually
Ceiling light F2 is also powered by the same line, and has a switch for manual operation.
The ceiling light timer N10 – located under the rear seat – is powered by the line of fuse F16, and is also protection-powered (this allows interruption of the timing when the key is turned to MAR), by fuse F3 of fuse box G1 "C". Receives a signal (earth) to open the doors from one of the four switches located on the door locking devices P10, P11, P12 or P13; the timed control signal is thus sent to the two ceiling lights F3 and F2.
It also receives the boot opening signal from the relative switch H24, and consequently sends a timed command to ceiling light F5.
