DESCRIPTION - COURTESY LIGHTS - Fiat GRANDE PUNTO 1.9 Multijet
There is only one bulb in the front courtesy light which can be switched on or off using the relevant switch or through a delay timer as described below.The courtesy light operation is timed according to a logic managed by the body computer:- when any of the doors is opened, it comes on for 3 seconds; the timer is reactivated whenever the door is opened;- when all the doors are closed; the lights stay on for a further 10 seconds with the key off. This time is interrupted if the key is moved to key on position: in this case, the courtesy lights are turned off immediately.- When all the doors are closed at key-on the courtesy lights are immediately switched off.- when the key is removed, the courtesy light comes on and a 10 second timer is activated.- all the courtesy lights are turned off immediately at the door lock control;- at the door release command, the courtesy light is turned on and a 10 second timer is activated.- If the inertia switch is operated the courtesy light comes on for 15 minutes.The switching on or off takes place gradually (dimmer) with the cycle lasting 2 seconds.The courtesy light power supply follows a battery voltage control logic: with the key off when any door or the boot is opened, a time of 15 seconds is set. After this, all the courtesy light is deactivated.If one or more doors are open, this is shown on the instrument panel display; the warning light remain on until all the vehicle doors and boot lid are properly shut. If a given speed limit is exceeded, this is also signalled by means of a buzzer.
