Maintenance and Care
Always use washer fluid when using
the wipers to remove salt or dirt from
a dry windshield.
Avoid using the wiper blades to
remove frost or ice from the
windshield. Keep the blade rubber out
of contact with petroleum products
such as engine oil, gasoline, etc.
Spray nozzles
If the jet does not work, first check
that there is fluid in the pan (see
paragraph "Level checks" in this
section) then check that the nozzles
are not clogged.
Blades Replacement
• Move the wiper arms into "Service"
position, as previously described and
lift them.
• Press the indicated button, slip off
the blade support from the arm and
replace it.

• Return the blade to its original
position on the windscreen.
• Turn the multifunction lever to one
of the automatic settings (see
chapter "Windshield Wipers and
Washers" in section 3) and move the
ignition switch to the RUN position:
the wiper arms will return to the
resting position.
NOTE:
Due to the difficulty of this operation,
we recommend that you contact the
Maserati Service Network for
replacement of the blades.
Body Lubrication
Locks and all body pivot points,
including such items as seat tracks,
door hinge pivot points and rollers,
liftgate, tailgate, sliding doors and
hood hinges, should be lubricated
periodically with a lithium based
grease, to assure quite, easy operation
and to protect against rust and wear.
Prior to the application of any
lubricant, the parts concerned should
be wiped clean to remove dust and
grit; after lubricating excess oil and
grease should be removed. Particular
attention should also be given to hood
latching components to ensure proper
function. When performing other
underhood services, the hood latch,
release mechanism and safety catch
should be cleaned and lubricated. The
external lock cylinders of the front
doors should be lubricated twice a
year, preferably in the Fall and Spring.
Apply a small amount of high quality
lubricant directly into the lock cylinder.
