Windshield wipers
Windshield wipers
Clean the rubber parts regularly using
the specific products.
Replace the blades if the edge of the
rubber is deformed or worn. In any
case, the blades should be replaced
approximately once a year.
Travelling with worn wiper
blades is very dangerous
because it reduces the
visibility in the event of poor
atmospheric conditions.
The windshield wiper arms
have to be replaced with new
ones after two disassembling
operations. The special arm fixing
system helps ensure the proper
mechanical stability only for the first
two refitting operations, provided
that the specified tightening torque is
observed.
We recommend therefore that
you have any interventions
involving the removal of the
windshield wiper arms carried out at
your local Authorized Maserati Dealer.
Some simple measures may reduce the
possibility of damage to the blades.
– In the case of temperatures below
freezing, check that ice has not stuck
the rubber part against the
windshield. If necessary, use an anti-
freeze product to detach it.
– Remove any snow that has
accumulated on the windshield: as
well as protecting the blades, this
avoids forcing and overheating the
wiper’s electric motor.
– Do not operate the wipers when the
windshield is dry.
Spray nozzles
If the spray nozzle does not work, first
check that there is fluid in the tank (see
“Level checks” in this section) then
check that the nozzles are not clogged.
Replacing the windshield wiper
blades
Due to the difficulty of this operation,
we recommend that you contact your
local Authorized Maserati Dealer for
replacement.
