quantity of nontoxic gas is generated
to inflate the advanced front air bags.
The steering wheel hub trim cover and
the upper right side of the dashboard
separate and fold out of the way as
the air bags inflate to their full size.
The air bags then quickly deflate while
helping to restrain the driver and
front passenger. The advanced front
air bag gas is vented through the vent
holes in the sides of the air bag. In this
way, the air bags do not interfere with
your control of the vehicle.
Supplemental Driver Side Knee Air
Bag Inflator Unit
The supplemental driver side knee air
bag unit is located in the dashboard
trim beneath the steering column.
When the ORC detects a collision
requiring the air bag, it signals the
inflator units. A large quantity of
non-toxic gas is generated to inflate
the supplemental driver side knee air
bag. The trim cover separates and
folds out of the way allowing the air
bag to inflate to the full size.
Supplemental Seat-Mounted Side Air
Bag (SAB) Inflator Units
The ORC unit determines if a side
collision requires the side air bags to
inflate, based on the severity and type
of collision. Based on the severity and type of collision, the side air bag
inflator on the crash side of the
vehicle may be triggered, releasing a
quantity of nontoxic gas.
The inflating SAB exits through the
seat seam into the space between the
occupant and the door. The side air
bag moves at a very high speed and
with such a high force that it could
injure you if you are not seated
properly, or if items are positioned in
the area where the side air bag
inflates. This especially applies to
children.
Supplemental Side Air Bag Inflatable
Curtain (SABIC) Inflator Units
During collisions where the impact is
confined to a particular area of the
side of the vehicle, the ORC may
deploy the SABIC air bags, depending
on the severity and type of collision. In
these events, the ORC will deploy the
SABIC only on the impact side of the
vehicle. A quantity of non-toxic gas is
generated to inflate the side curtain
air bag.
The inflating side curtain air bag
pushes the head/s of the occupant/s
seating in the outside seats from the
edge of the headliner out of the way
and covers the window. The air bag
inflates with enough force to possibly injure you if you are not belted and
seated properly, or if items are
positioned in the area where the side
curtain air bag inflates. This especially
applies to children.
The SABICs may also help reduce the
risk of partial or complete ejection of
vehicle occupants through side
windows in certain rollover events
(because equipped with rollover
sensing).
Front and Side Impact Sensors
In front and side impacts, impact
sensors can aid the ORC in
determining appropriate response to
impact events.
Enhanced Accident Response System
In the event of an impact causing air
bag deployment, if the
communication network and the
power remains intact, depending on
the nature of the accident, the ORC
will determine whether the enhanced
accident response system will have to
perform the following functions:
• cut off fuel to the engine;
• turn hazard lights and interior lights
on as long as the battery has power
or until the ignition switch is turned
off;
• unlock the doors automatically;Before Starting

Defroster
Check
operation by
selecting the
defrost mode and place the fan system
on high speed (see “Air Conditioning
Controls” chapter in section
“Dashboard Instruments and
Controls”).
You should be able to feel the air
directed against the windshield and
front side windows. Contact
Authorized Maserati Dealer for service
if your defroster is inoperable.
Floor Mat
Always use floor mats designed to fit
the footwell of your vehicle. Use only
floor mats that leave the pedal area
unobstructed and that are firmly secured so that they cannot slip out of
position and interfere with the pedals
or impair safe operation of your
vehicle.
NOTE:
The Authorized Maserati Dealer can
provide you with any information
about the available Maserati floor
mats included in the “Genuine
Accessories” range.
WARNING!
Pedals that cannot move freely can
cause loss of vehicle control and
increase the risk of serious personal
injury.
• Always make sure that floor mats
are properly attached to the proper
fasteners.
• Never place or install floor mats or
other floor coverings in the vehicle
that cannot be properly secured to
prevent them from moving and
interfering with the pedals.
• Never put floor mats or other floor
coverings on top of already installed
floor mats. Additional floor mats and
other coverings will reduce the size
of the pedal area and interfere with the pedals.
• Check mounting of mats on a regular
basis. Always properly reinstall and
secure floor mats that have been
removed for cleaning.
• Always make sure that objects
cannot fall into the driver footwell
while the vehicle is moving. Objects
can become trapped under the brake
pedal and accelerator pedal causing
a loss of vehicle control.
• Mounting posts must be properly
installed, if not equipped from the
factory. Failure to properly follow
floor mat installation or mounting
can cause interference with the
brake pedal and accelerator pedal
operation causing loss of control of
the vehicle.
Tires
•
Examine tires for excessive tread
wear and uneven wear patterns.
• Check for stones, nails, glass, or other
objects lodged in the tread or
sidewall.
• Inspect the tread for cuts and cracks.
• Inspect sidewalls for cuts, cracks and
bulges.
• Check the wheel nuts for tightness.Before Starting

Daytime Running Lights (DRL) The lighting system uses the same
high or low intensity headlamps LED,
respectively, for the DRL lights and
front position lights.
DRL lights will turn on when the
twilight sensor is in “DAY” mode, the
engine is running and the light switch
is in
or “AUTO” position.
If a turn signal is activated, the DRL
LED on the same side of the vehicle
switches in position light function for
the duration of the turn signal
activation. Once the turn signal is
deactivated, the DRL LED will light up
again.
NOTE:
On Canadian vehicles DRL are always
on. On USA vehicles, the DRL lights
can be turned on and off using the
MTC+ System, see “MTC+ Settings” in
section “Dashboard Instruments and
Controls” for further information.
Bi-Xenon Headlight The gas-discharge (xenon) headlights
operate with an electric arc saturated
with Xenon gas under pressure,
instead of the incandescent filament.
The light produced is assuredly higher
compared to traditional light bulbs, in terms of quality (brighter light) as well
as of the span and positioning of the
illuminated area.
WARNING!
If xenon headlamp replacement is
necessary, contact the Authorized
Maserati Dealer only: DANGER - RISK
OF ELECTRICAL SHOCK.
“Full-LED” Headlight with
Cornering Function These headlamps combine the
cornering function to the “Full-LED”
technology consisting of an additional
LED module which turns on when two
conditions occurs: the driver turns the
steering wheel or the driver activates
the turn indicator. The cornering
function will illuminate the corner to
enhance the visibility to the driver as
long as speed will be lower than 25
mph (40 km/h). “Full-LED” Technology
This technology creates headlights
with a simpler construction and a
more compact size compared to those
equipped with traditional or Xenon
light bulbs.
Other advantages are:
• a clearer light beam, with a cool
white tone that allows a better
perception of the contrasts thus
making the night vision more
efficient and less tiring;
• a longer duration equivalent at least
to that of the vehicle;
• a reduced current consumption.
These features positively affect some
vehicle management economy aspects
by eliminating/reducing the light bulb
replacements and help limit fuel
consumption.Understanding the Vehicle

overall conditions should also be
checked monthly. Tire pressures
change by approximately 1 PSI (0.07
bar) per 12°F (7°C) of air temperature
change. Keep this in mind when
checking tire pressure inside a garage,
especially in winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature =
32°F (0°C) then the cold tire inflation
pressure should be increased by 3 PSI
(0.21 bar) for every 12°F (7°C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6
PSI (0.13 to 0.4 bar) during operation.
DO NOT reduce this normal pressure
build-up or your tire pressure will be
too low. After inspecting or adjusting
the tire pressure, always reinstall the
valve stem cap. This will prevent
moisture and dirt from entering the
valve stem, which could damage the
valve stem and the TPMS sensor
connected to it.
Tread Wear Indicators Tread wear indicators are in the
original equipment tires to help you
determine when your tires should be
replaced.
These indicators are molded into the
bottom of the tread grooves. When the tread is worn to one of the
tread wear indicators, the tire should
be replaced.
WARNING!
The wet performance (aquaplaning
resistance) will decrease
proportionally to the thickness of the
tread.
Tires Durability The service life of a tire depends on
various factors including, but not
limited to:
• driving style;
• tire pressure;
• distance driven.
WARNING!
Tires and the spare tire (if equipped)
should be replaced after six years,
regardless of the remaining tread.
Failure to follow this warning could
result in tire failure. Replacement Tires NOTE:
In order to maintain high performance
and safety level under all driving
conditions, Maserati strongly
recommends to use tires equivalent to
the originals in size, quality and
performance when replacement is
needed.
For the size designation of your tire
see the label on the driver's side rear
door pillar or see table “Wheels” in
section “Features and Specifications”.
The “Load Index” and “Speed
Symbol” for your tire will be found on
the original equipment tire sidewall.
NOTE:
Maserati recommends Maserati
Genuine Tires marked with “MGT”
logo specifically designed for its
models.
It is recommended to replace the two
front tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle’s handling.
If you ever replace a wheel assembly,
make sure that the wheel’s
specifications (valve, TPMS sensor and
tire) match those of the original
wheels. Failure to use equivalentDriving

replacement tires may adversely affect
the safety, handling, and ride of your
vehicle.
Your Authorized Maserati Dealer is
available to provide suggestions as to
the types of tires most suited to the
use foreseen by the Customer.
WARNING!
• Do not use a tire, wheel size or
rating other than that specified for
your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and
performance characteristics,
resulting in altered steering,
handling, and braking operations of
the vehicle. This can cause
unpredictable handling and stress to
steering and suspension
components. Use only the tire and
wheel sizes with load ratings
appointed for your vehicle.
• Never use a tire with a smaller load
index or capacity, other than what
was originally equipped on your
vehicle. Using a tire with a smaller
load index could result in tire
overloading and failure.
• Always check the maximum speed
rating on the tire sidewall on any tire on the vehicle.
• Never exceed the maximum speed
rating of the tires. Risk of accident
and serious personal injury due to
excessive speed.
• Failure to equip your vehicle with
tires having adequate speed
capability can result in tire failure.
CAUTION!
Replacing original tires with tires of a
different size may result in false
speedometer and odometer readings.
Winter Tires These tires are specially designed for
driving on snow and ice and are fitted
to replace the ones supplied with the
vehicle. Winter or all-season tires can
be identified by the M+S (Mud &
Snow) or 3PMSF (3 Peaks Mountain
Snow Flake) designation on the tire
sidewall.
Before mounting winter tires, contact
an Authorized Maserati Dealer to
receive the technical information
necessary to advise you on wheel and
tire compatibility.
As to the type of tires to use, inflation
pressures and winter tires specifications, carefully follow the
indications as reported in the
“Technical Data” and “Tire Inflation
Pressure” chapters in section “Features
and Specifications”.
WARNING!
The standard tires profile and rubber
mixture are optimized for wet and dry
driving conditions. Standard tires may
not prove favorable for snow
conditions.
NOTE:
Snow
tires should have the same load
capacity as original equipment tires
and should be mounted on all four
wheels.
Snow Chains Maserati approved traction devices (or
snow chains) may be used to improve
traction on compacted snow in heavy
snow conditions.
The use of snow chains is specified by
local regulations of each country.
Use snow chains of reduced
dimensions, with a maximum
projection of 0.23 in (6 mm) beyond
the tire tread.Driving

off until the tire pressure is equal or
above the recommended cold inflation
pressure. Once the low tire pressure
warning light
illuminates, you must
increase the tire pressure to the
recommended cold inflation pressure
in order for the TPMS light
to turn
off. The system will automatically
update and the TPMS light
will turn
off once the system acquires the
correct tire pressure.
The vehicle may need to be driven for
up to 20 minutes above 15 mph
(24 km/h) in order for the TPMS to
acquire and process the updated
setting. 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
style. Aftermarket wheels can cause
sensor damage. Do not use aftermarket tire sealants or balance
beads if your vehicle is equipped
with a TPMS, as damage to the
sensors may result.
• The system can temporarily
experience radio-electric
interference emitted by devices
using similar frequencies.
• After inspecting or adjusting the tire
pressure, always reinstall the valve
stem cap. This will prevent moisture
and dirt from entering the valve
stem and damage the TPMS internal
sensor.
NOTE:
• Driving
on a
significantly
underinflated tire causes the tire to
overheat and may lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.
• The TPMS is not a substitute for
proper tire maintenance, and it is the
driver’s responsibility to maintain
correct tire pressure using an
accurate tire pressure gage, even if
under-inflation has not reached the
level to trigger illumination of the
TPMS light
.
• Seasonal temperature changes will
affect tire pressure, and the TPMSDriving
