Safety
WARNING!
• Improperly inflated tires can be
dangerous.
• Under-inflation increases tire flexing
and can result in tire overheating.
• Over-inflation reduces a tire's ability
to cushion shock. Objects on the
road and potholes can cause
damage that results in tire failure.
• Over-inflated or under-inflated tires
can affect vehicle handling and can
fail suddenly, resulting in loss of
vehicle control.
• Unequal tire pressures can cause
steering problems.
• Unequal tire pressures from one side
of the vehicle to the other can cause
the vehicle to drift to the right or
left.
• Always drive with each tire inflated
to the recommended cold tire
inflation pressure.
Economy
Improper
inflation pressures may
cause uneven wear patterns to
develop across the tire tread. These
abnormal wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under-
inflation also increases tire rolling
resistance resulting in higher fuel
consumption.
Ride comfort and vehicle stability
Proper tire inflation contributes to a
comfortable ride. Over-inflation
produces a jarring and uncomfortable
ride.
Tire Pressure Checkup The proper cold tire inflation pressure
is indicated on the driver's side rear
door pillar and on the table “Tire
Inflation Pressure” in section
“Features and Specifications”.
Inflation pressure specified on the
table always refers to “cold tire
inflation pressure”. Cold tire inflation
pressure is defined as the tire pressure
after the vehicle has not been driven
for at least three hours, or driven less
than 1 mi (1.6 km) after a three hour
period.
Check tire pressures more often in
case of significant outside
temperature changes, as tire pressure
varies according to temperature
changes.
The pressure should be checked and if
necessary adjusted; tire wear and 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.Driving

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 TPMS will monitor the actual tire pressure
in the tire.
Premium System The TPMS system uses wireless
technology with wheel rim mounted
electronic sensors to monitor tire
pressure levels. Sensors mounted to
each wheel as part of the valve stem
transmit tire pressure readings to the
receiver module.
The TPMS consists of the following
components:
• receiver module;
• four TPMS sensors;
• various TPMS messages, which
display on the instrument cluster;
• warning light
.
Tire Pressure Low Warning
The TPMS light will illuminate in
the instrument cluster and an acoustic
signal will notify that tire pressure is
low in one or more of the four tires.Driving

assemblies. After replacing all four
wheel and tire assemblies (road tires)
with tires not equipped with Tire
Pressure Monitoring System sensors,
drive the vehicle for 20 minutes above
15 mph (24 km/h). The TPMS will
chime, the TPMS light
will flash on
and off for 75 seconds and then
remain on and the instrument cluster
will display the “Service Tire Pressure
System” message and then display
dashes (--) in place of the pressure
values. Beginning with the next
ignition switch cycle, the TPMS will no
longer chime or display the “Service
Tire Pressure System” message in the
instrument cluster but dashes (--) will
remain in place of the pressure values.
To reactivate the TPMS, replace all four
wheel and tire assemblies (road tires)
with tires equipped with TPMS sensors.
Then, drive the vehicle for up to 20 minutes above 15 mph (24 km/h). The
TPMS will chime, the TPMS light
will flash for 75 seconds and then
turn off. The instrument cluster will
then display the “Service Tire Pressure
System” message.
The instrument cluster will also display
pressure values in place of the dashes
(--). On the next ignition switch cycle
the “Service Tire Pressure System”
message will no longer be displayed as
long as no system fault exists.
Radio Frequency Transmitter -
Regulatory Information The “Regulatory Information” for all
the radio and radar frequency devices
can be consulted by accessing the
"Services" section on the website
www.maserati.com.Fuel Requirements The engines are designed to meet all
environmental regulations and provide
excellent fuel economy and
performance when using unleaded
premium gasoline with an AKI octane
rating of 91 or above. AKI (Anti Knock
Index) is an average on the Research
Octane Number, RON, and the Motor
Octane Number, MON (RON + MON/2
gives you the AKI).
For vehicle top performance, use
unleaded premium gasoline with no
less than 93 minimum AKI octane
rating.
Poor quality gasoline can cause
problems such as hard starting,
stalling, and hesitations. If you
experience these symptoms, try
another brand of gasoline before
considering service for the vehicle at
an Authorized Maserati Dealer .
Besides using unleaded gasoline with
the proper octane rating, gasoline that
contain detergents, anti-corrosion and
stability additives are recommended.
Using gasoline that have these
additives may help improve fuel
economy, reduce emissions, and
maintain vehicle performance.Driving
