3.2.2 WARNING LIGHTS

The following warning lights are positioned on the lower part of the dashboard:

1 -

GENERATOR WARNING LIGHT (Red)

This warning light comes on and activates the acoustic alarm
when the starting circuit is energized and goes out when the en-
gine reachs the idling speed; if this warning light remains on even
when the engine is running at the normal operating speed, this
means that the alternator does not work and the battery is not
charged correctly.

IMPORTANT
• If the warning light remains off when the ignition key is

turned to position «I», this means that the alternator is
faulty or broken.

2 -

PREHEATING WARNING LIGHT (Yellow)

This warning light comes on when the ignition key is turned to po-
sition “

” to start the engine at low temperatures.

(See «3.6.2.2 STARTING WITH COLD ENGINE OR IN COLD
