Instrument panel backlighting is active only if the parking
light or the low/high beam is on.
In this case the instrument panel automatically turns on

Pilot lights brightness function

instrument panel according to the outer light measured.
Auto-off headlight function
This function allows you to reduce current consumption
from the battery, by automatically managing headlight
switching-off.

is switched off and will be turned on only upon the
following Key-ON.

switch is turned off.
Accommodated in the handgrip of each ignition key is an
electronic device that modulates an output signal. This
signal is generated by a special antenna incorporated in
the switch when the ignition is turned on and changes
every time. The modulated signal acts as a "password"
and tells the CPU that an "authorised" ignition key is
being used to start up the engine. When the CPU
recognises the signal, it enables engine start-up.
