White Bass box Bulb Replacement The signal failure of an external light
(turn signal, low beam and high beam,
license plate light, reverse light, brake
light and rear fog light) is
communicated to the instrument
cluster that displays on the TFT screen
the
or amber warning light
and a text message indicating which
light is faulty.
Front Headlights The light bulbs of the headlight
clusters are arranged as follows:
1 Bi-Xenon low-beam/high-beam
bulb.
2 Position light and DRL (*) LED.
3 Turn signal light bulb.
4 FTP bulb, headlight flashing.
5 Side marker bulb.
(*) On vehicles for the Canadian
market DRL are always enabled. CAUTION!
Due to the complexity of the
operation, for the replacement of the
headlight clusters light bulbs, we
recommend that you contact an
Authorized Maserati Dealer .
WARNING!
The headlamps are a type of high
voltage discharge tube. High voltage
can remain in the circuit even with the
headlamp switch and the ignition
switch off. Because of this, you should
not attempt to replace a headlamp
bulb yourself, but take the vehicle to
an Authorized Maserati Dealer for
service.Maintenance and Care
