•Never leave children alone in a
vehicle, or with access to an
unlocked vehicle.
•Allowing children to be in a vehicle
unattended is dangerous for a
number of reasons. A child or others
could be seriously or fatally injured.
Children should be warned not to
touch the parking brake switch,
brake pedal or the shift lever.
•Do not leave the key in or near the
vehicle, and do not leave the key in
the ignition switch in the ACC or
MAR (ON) position. A child could
operate power windows, other
controls, or move the vehicle.
•Do not leave children or animals
inside parked vehicles in hot
weather. Interior heat build-up may
cause serious injury or death.
•An unlocked car is an invitation to
thieves. Always remove the key
from vehicle, cycle the ignition
switch to STOP (OFF) and lock all
doors when leaving the vehicle
unattended.
•In the event of tampering with the
starter switch (e.g. attempted theft),
have it checked by an Authorized
Maserati Dealer before restarting
the vehicle.The key can be removed from the
ignition switch only when the
transmission shift lever is in position P
(Park).
If the transmission shift lever is shifted
to P (Park) after turning off the
engine, the key can only be removed
within 30 seconds from turning it to
STOP (OFF)position.
If you do not remove the key within
30 seconds, you will need to turn it
back toMAR (ON)and then toSTOP
(OFF)position to have a further 30
seconds within which to remove the
key.
In the event that the key unlocking
system fails or if it is not possible to
shift the transmission shift lever to P
(Park) position, to remove the key
from the ignition switch you must turn
it toSTOP (OFF)position, then:
• remove the cap indicated in the
picture using a pen or sufficiently
pointed tool;
• press the button just uncovered and
at the same time extract the key;
• once the key has been removed, refit
the cap.
WARNING!
After stopping the vehicle, always
shift the transmission shift lever to P
(Park).

The homologation number (EEC
regulations) of the radio control device
is indicated in the picture.
The current device feature is subject to
following conditions:
• This device may not cause harmful
interference.
• This device must accept any
interference received, including
interference that may cause
undesired operation.
If your transmitter device fails to
operate from a normal distance, check
for these two conditions:
• A weak battery in the transmitter
device. The expected life of the
battery in normal use is a minimum
of three years.
• Closeness to a radio transmitter such
as a radio station tower, airporttransmitter, and some mobile or CB
radios.Doors
WARNING!
•For personal security and safety in
the event of an accident, or robbery
lock the vehicle doors before you
drive as well as when parking and
leaving the vehicle unattended.
•When leaving the vehicle, always
remove the key and lock your
vehicle.
•Do not allow children to be in a
vehicle unattended or with access to
an unlocked vehicle. A child or
others could be seriously or fatally
injured. Children should be warned
not to touch the parking brake
trigger, brake pedal or the shift
lever.
•Do not leave the key in or near the
vehicle, and do not leave ignition
switch in the ACC or MAR (ON)
position. A child could operate
power windows, other controls, or
start the engine and the vehicle.
•Before opening a door, make sure
the maneuver can be performed
safely.

NOTE:
Front sensors are enabled only when
button LED is illuminated. In
addition, any pressing of
button
when vehicle speed is above 6 mph
(10 km/h) will be ignored by the
system.
Obstacle Signalling
The acoustic signals are emitted by
two buzzers, one under the dashboard
and one in proximity of the luggage
shelf.
When the obstacle is located at a
distance of less than 14 in (35 cm) from
the bumper, the beep is continuous.
The warning beep stops immediately if
the distance between the vehicle and
the obstacle increases. The tone cycle is
constant if the distance measured by
the central sensors remains unaltered.
If this occurs with the lateral sensors,
the signal stops after approximately 7
seconds, to prevent for example
continuous beeps in the event of
maneuvers alongside walls.
The distance from the obstacles can
also be graphically shown on the
instrument cluster display by means of
an image that shows the vehicle
surrounded by explanatory symbols of
the distance (maximum/average/minimum) and the position
(front/rear/central/side) of the obstacle
detected.
The color represents the distance,
while the field represents the position.
The green color represents the
maximum distance detected, the
yellow color the medium distance and
the red color the minimum one. The
rear sensors are not shown in the
image on the instrument cluster
display if only the front sensors are
active.
WARNING!
For the system to operate correctly the
sensors positioned on the bumper
must be kept clean (remove any mud,
dirt, snow or ice).
Sensor Range
The sensors allow the system to
monitor the front and rear of the
vehicle; they are positioned so as to
monitor the central and lateral zones
at the front and at the rear of the
vehicle.
In the event of an obstacle located in a
central area, this will be detected at
distances of less than 35 in (0,9 m) at
the front and 59 in (1,50 m) at the rear,
depending on the type of obstacle and
its dimensions.
If the obstacle is located in a lateral
position, it will be detected at
distances of less than 31 in (0,8 m).
Failure Indicators
The system ECU checks all the
components every time R (Reverse)
gear is engaged.
In the event that the parking sensors
fail, the relative
warning light and
message illuminate on the instrument
cluster display.
In the event of a failure signal, stop
the vehicle and turn the key in the
ignition switch toSTOP (OFF)position.
Then try cleaning the sensors or
moving the vehicle away from any
possible ultrasound sources (e.g.
pneumatic truck brakes or pneumatic

•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.
