TOWING TRAILERSWARNINGS AND
SUGGESTIONS For towing caravans or trailers the vehi-
cle must be fitted with a certified tow hook
and an adequate electric system. Installa-
tion should be carried out by specialised per-
sonnel 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 vehi-
cle 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 per-
sonal belongings.
Drive within the permitted speed limits for
vehicles with trailers. In any case the maxi-
mum speed should never exceed 100 km/h.
INSTALLING THE TOW HOOKThe towing device should be fastened to
the body by specialised personnel according
to the following instructions and any addi-
tional and/or integrative information sup-
plied by the Manufacturer of the device.
The towing device must meet current reg-
ulations with reference to 94/20/EC Di-
rective and subsequent amendments.
For any version the towing device used
must match the towable weight of the ve-
hicle on which it is to be installed.
For the electric connection a unified con-
nector should be used which is generally
placed on a special bracket normally fas-
tened to the towing device.
The ABS system with
which the car may be fitted
does not control the trailer braking
system. Particular care is therefore
necessary on slippery surfaces.
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.

INSTALLATION LAYOUT
(fig. 1)
The tow hook structure must be fastened
in the points shown by the symbol
Ø
us-
ing 4 M8 screws and 7 M10 screws.
Inner plate (2) should be at least 6 mm
thick.
Inner plate (3) should be at least 4 mm
thick.
Outer plate (4) should be at least 5 mm
thick.
The fastening points (1) must be fitted
with spacers with 25 mm diameter and 6
mm thickness. For the electrical connection, a 7 pin
12VDC connection is to be used
(CUNA/UNI - 9128 Standard). Follow the
instructions provided by the car manufac-
turer 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. 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.WARNINGIt is compulsory to fasten a
label (clearly visible) of suitable size and
material at the height of the hook ball with
the wording:
MAX. LOAD ON BALL 60 kg
After assembly, the fas-
tening screw holes should
be sealed to prevent the infiltra-
tion of exhaust gas.

STARTING BY INERTIA
IN THE EVENT OF A
PUNCTUREWARNINGIf the car is equipped with
“Fix&Go kit for tyre quick repair”, see the
instructions contained in the following
chapter.GENERAL INSTRUCTIONSWheel changing and correct use of the jack
and compact spare wheel call for some pre-
cautions as mentioned below. Never push, tow or coast
start the vehicle. This could
cause fuel to flow into the
catalyst damaging it irreversibly.
Remember that the engine
brake and power steering
are not operational until the engine
is started, therefore, much greater
effort than usual is needed on the
brake pedal and steering wheel.
WARNING
Signal the presence of the
stationary vehicle accord-
ing to the current regulations: haz-
ard warning lights, reflecting tri-
angle, etc.
Any passengers should leave the
car and wait for the wheel to be
changed out of harm of the traffic.
If parked on a slope or uneven road
surfaces, place wedges or other
suitable devices under the wheels
to prevent the car from rolling.
Never start the engine when the
car is raised on the jack.
When towing a trailer, always
remove the trailer before lifting
the car.

– Fully tighten the bolts in the sequence
shown in fig. 8, without refitting the cap.REFITTING A NORMAL WHEEL– Following the procedure described pre-
viously, raise the car and remove the spare
wheel.
For versions with steel rims:
– Fit a normal wheel bearing in mind that
the pin (B-fig.7) must match one of the
holes (A-fig.7).
– Make sure that the contact surfaces of
the compact spare wheel with the hub are
clean and free of impurities which may lat-
ter cause the fastening bolts to slacken.– Screw the fastening bolts.
– Tighten the bolts following the order pre-
viously described for the compact spare
wheel fig. 7.
– Place the cap near the wheel so that the
inflating valve can come out through the
countersunk hole. Press the wheel circum-
ference starting from the area next to the
valve countersunk hole until it is complete-
ly inserted.
For cars with alloy rims:
– Tighten the pin (A-fig. 9) in one of
the fastening bolt holes.
– Fit the wheel on the pin and fasten it
with four bolts.
– Remove the centering pin (A-fig. 9)
and tighten the last bolt.
– Lower the car and remove the jack; then
tighten the bolts as described previously for
the spare wheel (fig. 7).
WARNINGIncorrect fitting might cause
the wheel cap to come off when the car is
on the move.After refitting the wheel:
– stow the spare wheel in the space pro-
vided in the luggage compartment;
– insert the jack in its container forcing it
lightly to prevent it from vibrating during
travelling;
– place the tools used in the housings pro-
vided on the support;
– place the tool container on the spare
wheel and secure everything with the clamp-
ing device (A-fig. 2).fig. 8

IF THE VEHICLE IS TO BE TOWEDThe tow ring supplied with the vehicle is
housed in the tool box under the boot mat.
To install the tow ring, proceed as follows:
– Take the tow ring from the tool box.
– Remove the cover (A) snap-fitted on the
front (fig. 77) or rear bumper (fig. 78).

Carefully clean the thread-
ed housing before tighten-
ing the ring. Before beginning to
tow the car make sure that the
tow ring is firmly tightened in its
threaded housing.
WARNING
Before beginning to tow
the car, turn the ignition
key to MAR and then to STOP, do
not remove it. Removing the key
automatically engages the steering
lock resulting in the impossibility
to steer the wheels. When towing
remember that without the help of
the servo-brake and power steer-
ing, it is necessary to exert more
effort on the brake pedal and for
steering. Do not use flexible cables
for towing and avoid jerks. Dur-
ing towing operations make sure
that fastening the joint to the car
does not damage the components
in contact with it. When towing the
car it is compulsory to comply with
the specific traffic regulations con-
cerning both the towing device and
behaviour on the road.

(2.5 V6 24V Q-SYSTEM)WARNINGFor towing the vehicle com-
ply with current local regulations. Also fol-
low the instructions given on the previous
page.
If the car needs to be towed, observe the
following recommendations:
– if possible, put the car on a rescue ve-
hicle;
– if this is not possible, tow the car rais-
ing the driving wheels (front) from the
ground;
– if this, too, is not possible, the car may
only be towed for 50 Km at a speed of
50 km/h.
The gearshift lever should be at position N
for towing.The failure to follow the
above instructions may
cause serious damage to
the automatic gearbox.
Cars with automatic gear-
box may be towed only for
short distances and at a
low speed: if longer towing is nec-
essary, the driving wheels must be
raised to prevent the gearbox from
being pulled into rotation during
towing.
Do not start the engine
when towing the vehicle.
WARNING
Do not start the engine
when the vehicle is being
towed.
