Maintenance and Care
Information” in section “Safety”).
The thinner is the tread, the greater
is the risk of skidding.
•
Drive carefully on wet roads to
decrease the risk of aquaplaning.
Winter Tires
These tires are specially designed for
driving on snow and ice and are fitted
to replace the ones supplied with the
vehicle.
The functions of these tires are
significantly reduced in winter when
tread depth is less than 4 mm (0.157
in). In this case, they should be
replaced.
The specific functions of the winter
tires lead to lower performance under
normal environmental conditions or on
long highway trips, compared to the
standard tires.
Therefore, their use should be limited
to the situations and performance for
which they have been type-approved.
The
Service Network can provide all
necessary information about fitting
winter tires on the vehicle.
NOTE:
• We recommend fitting winter tires
on the vehicle at temperatures 7
°
C
(45
°
F) since the driving performance
of summer tires is reduced at low
temperatures. Summer tires may be
permanently damaged at extremely
low temperatures.
• Comply with all state and local laws
governing snow tire and tread depth
requirements.
Wheel Rims Maintenance
All wheel rims should be cleaned
regularly with a mild soap and water.
To remove heavy soil and/or excessive
brake dust, use a nonabrasive, non-
acidic cleaner.
Do not use scouring pads, steel wool, a
bristle brush, or metal polishes. Do not
use oven cleaner that may involve and
damage the brake calipers.
Avoid automatic car washes that use
acidic solutions or harsh brushes that
may damage the wheel rim protective
finish.
Bodywork Maintenance
and Care
Protection from Atmospheric
Agents
The main causes of corrosion are:
• atmospheric pollution;
• salinity and humidity in the
atmosphere (marine areas or a damp
climate);
• seasonal environmental conditions;
• salt scattered on the roadbed to melt
ice and snow.
The abrasive action of wind-carried
atmospheric dust and sand, mud and
stones should not be underestimated.
On this vehicle, Maserati has adopted
the best technological solutions to
protect the bodywork from corrosion.
The main measures are:
• paint products and systems that give
the vehicle particular resistance to
corrosion and abrasion;
• use of galvanized (or pre-treated)
metal sheets which are highly
resistant to corrosion in the most
exposed parts;
• spraying of the underbody, engine
compartment, insides of wheel
housings, and other structures with
wax products having high protective
power;
