Glass Surfaces
All glass surfaces should be cleaned on
a regular basis with any commercial
household-type glass cleaner.
Never use an abrasive type cleaner.
Use caution when cleaning the inside
rear window equipped with electric
defrosters. Do not use scrapers or
other sharp instrument that may
scratch the electric elements.
When cleaning the rearview mirror,
spray cleaner on the towel or rag that
you are using. Do not spray cleaner
directly on the mirror.
Labels can be peeled off after soaking
with warm water.
Keep all objects a safe distance from
the window.
Cleaning Headlights
Your vehicle has plastic headlights that
are lighter and less susceptible to
stone breakage than glass headlights.
Plastic is not as scratch resistant as
glass and therefore different lens
cleaning procedures must be followed.
To minimize the possibility of
scratching the lenses and reducing
light output, avoid wiping with a drycloth. To remove road dirt, wash with
a mild soap solution followed by
rinsing.
Do not use abrasive cleaning
components, solvents, steel wool or
other aggressive material to clean the
lenses.
Moldings and Aluminum Trims
• For cleaning moldings and aluminum
trims, avoid the use of acidic or
alkaline cleaning agents that can
destroy the protecting surface
treatment.
• After washing aluminum trim with
warm water, apply the cleaning
agent with a clean tissue or a soft
sponge on the surface. Do not use
any other equipment such as
brushes, steel wool, abrasives or any
other equipment for cleaning.
• After cleaning, please rinse the
aluminum trim with a lot of clear
water.
• While cleaning in the car, please
make sure that the moldings and
aluminum trims only get in contact
with soft brushes or textiles.
Engine Compartment
At the end of each winter season,
carefully wash the engine
compartment, remembering to avoiddirecting the jet of water for too long
on the ECUs and other electric parts.
To perform this operation, you must
contact anAuthorized Maserati
Dealer.
