WARNING
The ABS with which the car may be
equipped will not control the braking
system of the trailer. Particular caution is
required on slippery roads.
WARNING
Never modify the braking system of the
car to control the trailer brake.The
trailer braking system must be fully
independent of the car ’s hydraulic system.
INSTALLING THE TOW HOOK
The towing device should be fastened to the
bodywork 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 Directive 94/20/EEC and subsequent
amendments. For any version the towing device
used must be right for the towable weight of the
car on which it is to be installed.
IMPORTANT The use of auxiliary loads other than
external lights (electric brake, winch, etc.) must
be used with engine running.For the electric connection a unified connector
should be used, which is generally placed on a
special bracket fastened to the towing device, and a
special ECU should be installed on the car to
control the trailer's exterior lights.
7 or 13-pole 12 V DC connections should be used
(CUNA/UNI and ISO/DIN Standards). Follow
any instructions provided by the car manufacturer
and/or the towing device manufacturer.
An electric brake or winch should be powered
directly by the battery through a cable with a
cross-section of no less than 2.5 mm
2.
IMPORTANT Electric brakes or other devices must
be used with engine running.
In addition to the electrical branches, the vehicle's
electrical system can be connected only to the
supply cable for an electric brake and to the cable
for an internal trailer light, though not more than
15 W. For connections use the preset control unit
with battery cable no less than 2.5 mm2.

IN AN EMERGENCY
STARTING THE ENGINEContact a Fiat Dealership immediately if instrument
panel warning light
stays on constantly.
JUMP STARTING
If the battery is flat, the engine may be started using
an auxiliary battery with the same capacity or a
little higher than the flat one.
To start the vehicle, proceed as follows:
❒connect the positive terminals (sign + near the
terminal) of the two batteries with a jump lead
fig. 140❒with a second lead, connect the negative terminal
– of the auxiliary battery to an earthing point
on the engine or the gearbox of the car to be
started;
❒start the engine;
❒when the engine has been started, remove the
leads reversing the order above.
For versions with Start&Stop system, in case of
starting by auxiliary battery, refer to the paragraph
“Start&Stop system” in the chapter “Getting to
know your car”.
If after a few attempts the engine does not start, do
not persist but contact a Fiat Dealership.
IMPORTANT Do not directly connect the negative
terminals of the two batteries: sparks could ignite
explosive gas released from the battery. If the
auxiliary battery is installed on another car, prevent
accidental contact between metallic parts of the
two cars.
Never use a fast batter y-charger to star t
the engine as this could damage the
electronic systems of your car,
particularly the ignition and fuel supply control
units.
