2007 Lancia Musa trailer

FAILURE WARNINGS
See the “Warning lights and messages” chapter.
OPERATION WITH TRAILER
The system is preset for deactivating automatically
when the trailer electric cable plug is fitted into the
car tow hook socket.
Sensors are reactivated when removing the trailer
cable plug.GENERAL WARNINGS
❒When parking, take the utmost care to obstacles
set above or under the sensors.
❒Objects set close to car rear part, under certain
circumstances are not detected and could
therefore cause damages to the car.
❒Indications sent by the sensor can be altered by
dirt, snow or ice deposited on the sensors or by
ultrasound systems (e.g.: truck pneumatic
brakes or pneumatic hammers) set nearby the
car.

For proper operation, the parking sensors set on the bumpers shall be clean from mud, dirt, snow
or ice. When cleaning the sensors, take the utmost care to prevent their damaging; do not use
therefore dry or rough clothes. Sensors shall be washed with clean water and car detergent, if
required. In washing stations, clean sensors quickly keeping the vapour jet/high pressure washing
nozzles at 10 cm at least from the sensors.
WARNING
Parking manoeuvres however are always under the driver’s responsibility that
shall always check the absence of people, animals or objects in the manoeuvre
space. This system is just a help for the driver but he shall never reduce
important during dangerous manoeuvres even if performed at low speed.

CORRECT USE OF THE CAR

Roof rack/ski rack
Remove the roof rack or the ski rack from the roof
as soon as they are no longer used. These
accessories lower air penetration and adversely
affect consumption levels. When needing to carry
particularly voluminous objects, preferably use a
trailer.
Electric devices
Use electric devices only for the amount of time
needed. Rear heated window, additional headlights,
windscreen wipers and heater fan need a
considerable amount of energy, therefore increasing
the requirement of current increases fuel
consumption (up to +25% in the urban cycle).Climate control
The air conditioner is an additional load which
greatly affects the engine leading to higher
consumption (on average up to +20%). When the
temperature outside the vehicle permits it, use the
air vents where possible.
Spoilers
The use of non-certified aerodynamic items may
adversely affect air drag and consumption levels.

TOWING TRAILERS
IMPORTANT NOTES
For towing caravans or trailers the car must be
fitted with a certified tow hook and an adequate
electric system. Installation should be carried out by
specialised personnel who release a special
document for circulation on the road.
Install any specific and/or additional rear-view
mirrors as specified by law.
Remember that when towing a trailer, steep hills are
harder to climb, the braking spaces increase and
overtaking takes longer depending on the overall
weight.Engage a low gear when driving downhill, rather
than constantly using the brake.
The weight the trailer exerts on the car tow hook
reduces by the same amount the actual vehicle
loading capacity. To make sure the maximum
towable weight is not exceeded (given in the log
book) account should be taken of the fully laden
trailer, including accessories and personal
belongings.
Do not exceed the speed limits of the country you
are driving in. In any case do not exceed 100 km/h.

WARNING
Under no circumstances should the vehicle brake system be altered to control the
trailer brake. The trailer braking system must be fully independent of the vehicle’s
hydraulic system.
WARNING
The ABS system with which the car may be fitted does not control the trailer braking
system. Great care should therefore be taken when driving on slippery road surfaces.

INSTALLING THE TOW HOOK
The towing device should be fastened to the body
by specialised personnel according to any additional
and/or integrative information supplied by the
Manufacturer of the device.
The towing device must meet current regulations
with reference to 94/20/EC Directive and
subsequent amendments.
For any version the towing device used must match
the towable weight of the vehicle on which it is to
be installed.
For the electric connection a unified connector
should be used which is generally placed on a
special bracket normally fastened to the towing
device, and a special ECU for external trailer light
control shall be installed on the car. For the electrical connection 7 or 13 pins 12VDC
connection is to be used (CUNA/UNI and ISO/DIN
Standards). Follow the instructions provided by the
car manufacturer and/or the tow hitch
manufacturer.
An electric brake should be supplied directly by the
battery through a cable with a cross section of no
less than 2.5 mm
2.
IMPORTANT Electric brake or other device shall be
used with running engine.
In addition to the electrical branches, the car’s
electric system can only be connected to the supply
cable for an electric brake and to the cable for an
internal light, though not above 15W.
For connections use a preset control unit with
battery cable no less than 2.5 mm
2.

IMPORTANT - Engine oil
Should prevailing use of the car be under one of the
following specially heavy conditions:
❒trailer or caravan towing;
❒dusty roads;
❒short distances (less than 7-8 km) repeated and
with external temperatures below zero;
❒frequently idling engines or long distance low
speed driving (e.g. taxis or door-to-door
deliveries) or in case of a long term inactivity;
replace engine oil more frequently than required on
“Service schedule”.
IMPORTANT - Air cleaner
If the car is used on dusty roads change the air
cleaner more frequently than the indications in the
“Service schedule”.
If in doubt as to how often the engine oil and air
cleaner should be changed according to how you use
the car, contact a Lancia Dealership.IMPORTANT - Pollen filter
If the vehicle is used frequently in dusty or heavily
polluted environments it is advisable to replace the
filtering element more frequently; in particular it
should be replaced if a reduction of the amount of
air admitted to the passenger compartment is noted.
IMPORTANT - Diesel filter
The possibility of topping up with diesel fuel not
complying with EN590 European Norm might
make it necessary to replace the filter more
frequently than indicated in the “Service schedule”.
