that prevent the TPMS from
functioning properly. Always check the
TPMS malfunction telltale after
replacing one or more tires or wheels
on your vehicle to ensure that the
replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
General Information
The Tire Pressure Monitoring System
(TPMS) will warn the driver of a low
tire pressure according to the vehicle
recommended cold pressure indicated
on the table “Tire Inflation Pressure”
in section “Features and
Specifications” and on the label
applied on the driver's side at the base
of the rear door pillar.
The cold tire inflation pressure must
not exceed the maximum inflation
pressure molded into the tire sidewall.
Check “Tires – General Information” in
section “Driving” for information on
how to properly inflate the tires.
The tire pressure will also increase as
the vehicle is driven - this is normal
and there is no adjustment required
when this occurs.
The TPMS will warn the driver of a low
tire pressure if the tire pressure falls
below the low-pressure warning limit
for any reason, including lowtemperature effects and natural
pressure loss of the tire.
The TPMS will continue to warn the
driver of low tire pressure as long as
the condition persists and will not turn
off until the tire pressure is equal or
above the recommended cold
inflation pressure.
The TPMS monitors the tire pressure
by means of special sensors fitted
inside the wheel rims, in position with
the inflation valve.
These sensors transmit a signal that is
detected by the antenna integrated in
the ECU.
The ECU processes this information
and, via the CAN line, transmits a
series of tire pressure data and system
errors, if any, to the instrument cluster.
The display may show the information
received by means of specific screen
pages, which can be recalled by
pressing briefly the "MODE" button
(see "TFT Display: Controls" in chapter
"Instrument Cluster" of the section
Dashboard Instruments and
Controls").
WARNING!
The TPMS warns the driver that the
tire pressure has decreased. This
warning does not exempt the driver
from periodically checking the tires
and from complying with the
prescribed tire pressure levels.
CAUTION!
• The TPMS has been optimized for the original equipment tires and
wheels. TPMS pressures and warning
have been established for the tire
size equipped on your vehicle.
Undesirable system operation or
sensor damage may occur when
using replacement equipment that is
not of the same size, type, and/or

with the key removed to the ignition
switch.
• Remember that passing other vehicles when driving uphill is slower
and thus requires more free distance
on the road. If you are being
overtaken on a hill, slow down and
allow the other vehicle to pass.
Driving on Snow or Ice
Please consider some general advice
for driving in these conditions, listed
below.
• Maintain a very moderate speed.
• Fit snow chains or specific tires if the road is covered with snow: see the
paragraphs “Tires – General
Information” in this section.
• We recommend you to activate the “ICE” drive mode (see chapters
“Drive Mode” in this section).
• During the winter season, even apparently dry roads can have icy
sections. Be careful when crossing
bridges, viaducts and roads that have
little exposure to the sun and are
bordered by trees and rocks. They
may be icy.
• Keep an ample safe distance from the vehicles in front of you.
• Avoid sharp braking, sharp changes in direction and rapid acceleration. Rapid acceleration on snow covered
or icy surfaces may cause the driving
wheels to pull erratically to the right
or left. This phenomenon occurs
when there is a difference in the
surface traction under the rear
(driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces
is dangerous. Unequal traction can
cause sudden pulling of the rear
driving wheels. You could lose control
of the vehicle and possibly have a
collision. Accelerate slowly and
carefully whenever there is likely to be
poor traction (ice, snow, wet mud,
loose sand, etc.).
Driving through Flooded
Sections
Driving through more than a
centimeters deep shallow standing
water section will require extra
caution to ensure passenger safety and
prevent damage to your vehicle.
WARNING!
Do not drive on or across a road or
path where water is flowing and/or
rising (as in storm run-off). Flowing
water can wear away the road or path
surface and cause your vehicle to sink
into deeper water. Furthermore,
flowing and/or rising water can carry
your vehicle away swiftly. Failure to
follow this warning may result in
injuries that are serious or fatal to
you, your passengers, and others
around you.
Although your vehicle is capable of
driving
through shallow standing
water, consider the following Caution
and Warning before doing so.
CAUTION!
• Always check the depth of the standing water before driving
through it. Never drive through
standing water that is deeper than
the bottom of the tire rims mounted
on the vehicle.
• Determine the condition of the road or the path that is under water and if
there are any obstacles in the way
Driving

NOTE:
•We recommend fitting winter tires
on the vehicle at temperatures 45 °F
(7 °C) 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 trims 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
affect 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;
• spraying of plastic materials, with a protective function, in the most
exposed points: underneath the
doors, inside part of the mud guards,
edges, etc.;
• use of ventilated box sections, coated with protective wax products,
to avoid condensation and trapped
water which could encourage the
formation of internal rust.
Useful Advice to Keep the
Bodywork in Good Condition
Paint
The paintwork does not only have an
aesthetic function but also protects
the underlying metal sheets. In the
event of abrasions or deep scratches,
we recommend to have the necessary
touch-ups made immediately, to avoid
any rust formation. Touch-ups do not
feature particular difficulties, even on
metallic finishes.
For all paint touch-ups, use only
original products indicated on the
plate applied inside the hood.

symbol with tape, to prevent it from
being detached by the revolving
brushes.
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 dry cloth. 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 avoid directing the jet of water for too long
on the ECUs and other electric parts.
To perform this operation, you must
contact an
Authorized Maserati
Dealer.
