•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.
• Check the tires (see “Tire Inflation
Pressure” chapter in section
“Features and Specifications”) for
proper cold inflation pressure.
Lights and Indicator Lights
• Have someone observe the
operation of exterior lights while
you operate the controls (see
“Lights” chapter in section
“Understanding the Vehicle”).
• Check turn signal and high beam
indicator lights on the instrument
cluster (see “Instrument Cluster”
chapter in section “Dashboard
Instruments and Controls”).
Door Latches
• Check for positive closing, latching,
and locking of doors and trunk lid
(see chapter “Doors” and “Open and
Close the Trunk Lid” in this section).Fluid Leaks
• Check area under vehicle after
overnight parking for recent fluid
leaks (oil, fuel, etc.).
• If gasoline fumes are detected or
fluid leaks are suspected, contact an
Authorized Maserati Dealer.

Tire and Loading Information Label
The proper cold tire inflation pressure
is listed on the driver's side rear door
pillar.
This label tells you important
information about the:
• Number of people that can be
carried in the vehicle.
• Total weight the vehicle can carry.
• Tire size designed for the vehicle.
• Cold tire inflation pressures for the
front, rear, and spare tires.
Loading
The vehicle maximum load on the tire
must not exceed the load carrying
capacity of the tire on your vehicle.
You will not exceed the tire's load
carrying capacity if you adhere to the
loading conditions, tire size, and cold
tire inflation pressures specified onthe “Tire and Loading Information
Label” and in the “Features and
Specifications” section.
NOTE:
Under a maximum loaded vehicle
condition, gross axle weight ratings
(GAWRs) for the front and rear axles
must not be exceeded.
Tires
Driving over rough or damaged road
surfaces, as well as debris, curbs and
other obstacles can cause serious
damage to wheels, tires, and
suspension parts.
This is more likely to occur with
low-profile tires, which provide less
cushioning between the wheel and
the road.
Be careful to avoid road hazards and
reduce your speed, especially if your
vehicle is equipped with low profile
tires.
WARNING!
Overloading of your tires is
dangerous. Overloading can cause tire
failure, affect vehicle handling, and
increase the stopping distance. Use
tires of the recommended load
capacity for your vehicle. Never
overload them.
Department of Transportation
Uniform Tire Quality Grades
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by
the tire's manufacturer in each
category is shown on the sidewall of
the tires on your vehicle.
