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
oramber warning light
and a text message indicating which
light is faulty.
Front Headlights
The light bulbs of the headlight
clusters are arranged as follows:
1Bi-Xenon low-beam/high-beam
bulb.
2Position light and DRL (*) LED.
3Turn signal light bulb.
4FTP bulb, headlight flashing.
5Side 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.
Tail-Light Clusters Light Bulbs
The taillight bulbs are arranged as
follows:
1Position light guide LED.
2Stop light LED.
3Turn signal LED.
4Reverse light bulb.
5Rear fog light bulb.
Tail-Light Clusters Bulbs
Replacement
Most of the lamps of the taillight are
LED powered and cannot be replaced
individually. The only exceptions are
the reverse and the rear fog light
bulbs for which you find below the
replacement procedure.
Contact anAuthorized Maserati
Dealerto locate the correct parts and
replace them.
