1. Check the indicator lights and the engine preheating
When you turn the key in position (I) the instrument starts the automatic test and the display
shows "The Self Test Mode Is In Operation." The test mode lasts 10 seconds during which
time the buzzer sounds three times and the instrument flashes. Do not start the engine during
the instrument testing phase.
The glow plugs alarm ("PRE HEAT CHECK" on the instrument or the related indicator light, if
included in the panel) is turned on during the initial phase until the complete pre-heating of the
engine (the time depends on ambient temperature). At the end of the preheating phase it turns
off.
Do not start the engine if the glow plugs alarm (or its indicator) is not turned off.
