129) 130) 131)
39)
Versions with COMFORT-MATIC
transmission or DUALOGIC™
transmission
Make sure that the gearbox is in neutral
(N) (checking that the vehicle moves
when pushed) and proceed in the same
way as for towing a normal vehicle
with a manual transmission.
If the gear lever cannot be put in
neutral, do not tow the vehicle, but
contact a Fiat Dealership.
WARNING
129)Before towing, turn the ignition key to
MAR-ON and then to STOP without
removing it. The steering column
will automatically lock when the key is
removed and the wheels cannot be
steered.130)Before tightening the ring, clean the
threaded housing thoroughly. Make sure
that the ring is fully fastened in the housing
before towing the vehicle. Do not start
the engine whilst the vehicle is being
towed.
131)When towing, remember that greater
effort is required on the brake pedal in
order to brake, since the brake servo is not
providing assistance. Do not use flexible
cables when towing and avoid jerky
movements. During towing operations,
make sure that the fastened joint does not
damage adjoining components. When
towing the vehicle, it is necessary to obey
specific road regulations which relate
both to the towing device as well as to the
behaviour to adopt on the road. Do not
start the engine whilst the vehicle is being
towed.
WARNING
39)The front and rear tow hooks should
be used only for emergencies on the road.
You are allowed to tow the vehicle for
short distances using an appropriate
device in accordance with the highway
code (a rigid bar), to move the vehicle on
the road in readiness for towing or
transport via a breakdown vehicle. Tow
hooks MUST NOT be used to tow vehicles
off the road or where there are obstacles
and/or for towing operations using cables
or other non-rigid devices. In compliance
with the above conditions, towing must
take place with the two vehicles (one
towing, the other towed) aligned as much
as possible along the same centre line.
