Trailer Towing In this section you will find safety tips
and information on limits to the type
of towing you can reasonably do with
your vehicle.
NOTE:
• On the TROFEO version you can not
install the trailer tongue.
• Using original Maserati equipment
offers an advantage, compared to
aftermarket one, in terms of driving
safety and utilizing the vehicle
potential under all conditions,
especially considering that ESC and
AWD systems feature specific
settings for trailer towing. Further to
this, if vehicle use conditions so
allow, the original trailer tongue
allows use of the driver assist systems
present on-board.
• To maintain the new vehicle limited
warranty coverage, follow the
requirements and recommendations
in this chapter. Trailer Tongue Weight Maximum load of tow vehicle is
reduced by the trailer tongue weight
and the load on the same due to the
trailer. Trailer tongue weight increases
vehicle weight.
Do not exceed the maximum GVWR of
the tow vehicle, the one for each axle
(GAWR) and the mass that the vehicle
is rated to tow (GTW) specified on the
nameplate located on the rear of the
drivers door opening.
WARNING!
It is important that you do not exceed
the maximum allowed overall GVWR
and GTW. A dangerous driving
condition can result if either rating is
exceeded.
If you use aftermarket Kit for towing,
the maximum trailer load must not
exceed 6000 lb (2700 kg).
Arranging Load on Trailer Arrange load at the bottom and as
close as possible to trailer wheel axle.
In this way the trailer center of gravity
will be lower, thereby increasing the
driving safety of the vehicle-trailer
assembly. Always load a trailer with 60% of the
weight in the front of the trailer.
Loads bearing more on wheel axle, or
heavier in the rear of the trailer, can
cause the trailer to sway severely
side-to-side which could cause loss of
control of vehicle and trailer.
WARNING!
Failure to load trailers heavier in front
is the cause of many trailer accidents.
Never exceed the maximum tongue
weight stamped on your trailer hitch.
Tire Pressure Adjustment Proper tire inflation pressures of your
vehicle and trailer are essential to the
safe and satisfactory operation of your
vehicle while driving and in
maneuvers.
Check for signs of tire wear or visible
tire damage on trailer and vehicle
before towing a trailer.
For more information on vehicle tires,
see “Tires – General Information” in
this section.
When a trailer must be towed, inflate
vehicle tires to full load recommended
pressure (FLC) indicated in chapter
“Tire pressure” in section “Features
and Specifications”.Driving

For pressure of trailer tires, follow the
instructions given by the trailer
manufacturer.
After adjusting vehicle tire pressure
and connecting and disconnecting the
trailer, initialize the Tire Pressure
Monitoring System (TPMS) following
the instructions under chapter “Tire
Pressure Monitoring System (TPMS)” in
this section.
Field of Vision of External
Rearview Mirrors Law provisions require the field of
vision of external rearview mirrors to
include the rear trailer corners.
If vehicle external rearview mirrors
cannot cover the required field of
vision, it is possible to install additional
rearview mirrors sticking further out at
the sides.
The Authorized Maserati Dealer can
provide you with information about
towing a trailer and about the
approved components available in the
"Genuine Accessories" range. Trailer Lights Law provisions require trailers to be
equipped with an electrical lighting
system that must include the following
lights:
• Turn signals;
• Position lights;
• Stop lights;
• Rear fog lights;
• Reverse lights;
• License plate lights;
• Side marker lights (for trailer width
over 6.8 ft/2.1 m).
The power input of the trailer lights
must not exceed the values in the
following list.
• Position lights, side marker lights and
license plate lights :6x5Wper side.
• Rear fog lights :2x21W
• Turn signals :2x21W
• Stop lights :4x21W
• Reverse lights :2x21W
Minimum detectable current of Trailer
Tow Module (TTM): 100mA. Trailer Wiring Harness
Vehicle trailer tongue includes a 4-pin
sealed connector powered at 12VDC
for connection of the corresponding
trailer wiring connector.
In addition to the electrical branches,
the vehicle electrical system can only
be connected to the supply cable for
an electric brake and to the cable for
an internal light for the trailer, not
exceeding 15W.
CAUTION!
Do not cut or splice wiring into the
vehicle wiring harness. Do not change
cable connections on connectors. TheDriving

table below indicates the function and
section of wire corresponding to every
connector pin as shown in the figure.
If the hooking and/or the electrical
connection between vehicle and
trailer is faulty, the warning light and
the relevant message are displayed on
instrument cluster display (see
example in the figure). In these cases please contact an
Authorized Maserati Dealer and avoid
using the vehicle with a trailer.
Removing the Access Cover Before fitting the trailer tongue, the
access cover on the bottom part of the
rear bumper must be removed.
The cover is engaged in the bumper.
• Release cover inner side from
bumper, using the tip of a tool or screwdriver at the points indicated
by the arrows.
• Slide cover downward to disengage
the two projecting elements
indicated in the figure from bumper.
• Store cover in the luggage

• Refit the access cover making sure to
engage the two projecting elements
indicated by the arrow fully home
into the bumper.
• Push cover lower end toward
bumper until the two retainers click
in place.
Towing Tips • Before setting out on a trip, check
operation of trailer rear lights and stop lights to ensure you do not
jeopardize other road users' safety.
• Make certain that the load is secured
in the trailer and will not shift
during travel. When trailering cargo
that is not fully secured, dynamic
load shifts can occur that may be
difficult for the driver to control.
• When hauling cargo or towing a
trailer, do not overload your vehicle
or trailer. Overloading can cause a
loss of control, damage to brakes,
driveline, steering, suspension or
tires.
• Safety metal wire must always be
used between your vehicle and
trailer. Always connect the wire to
the hook retainers of the trailer and
vehicle hitch. Cross the wire under
the trailer tongue and allow enough
slack for turning corners.
• Comply with local applicable speed
limits.
• Towing any trailer will increase your
stopping distance. When towing,
you should allow for additional
space between your vehicle and the
vehicle in front of you. Failure to do
so could result in an accident.
• For towing use “Normal” ride
height. • Do not exceed maximum specified
pressure for vehicle and trailer tires.
• Vehicles with trailers should not be
parked on a steep grade. When
parking, put the tow vehicle
transmission in P (Park) and apply
the parking brake on the tow
vehicle. Always, block or "chock" the
trailer wheels.
• Do not use electronic Cruise Control
(CC and/or ACC) when driving on
slopes or when carrying heavy loads.
• The D (Drive) gear must be selected
when towing. The transmission
controls include a drive strategy to
avoid frequent shifting when
towing. However, if frequent
shifting does occur while in D
(Drive), if provided, you can use the
paddle shift switches to manually
select a lower gear.
• Using a lower gear while operating
the vehicle under heavy loading
conditions, will improve
performance and extend
transmission life by reducing
excessive shifting and heat buildup.
This action will also provide better
engine braking.Driving
