WARNING
170) Before towing, turn the key to MAR
and then to STOP without extracting it.
If the key is removed, the steering lock will
come on automatically and it will be
impossible to steer the wheels.
171) Before tightening the ring clean the
threaded housing thoroughly. Make sure
that the ring is fully fastened in the housing
before towing the car.
172) The (front/rear) tow hook must be
used exclusively for roadside assistance
operations. 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 tow truck. The tow hook
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.
173) Whilst towing, remember that as the
assistance of the brake servo and the
electric power assisted steering is
not available, greater force needs to be
exerted on the brake pedal and more effort
is required on the steering wheel. Do not
use flexible cables when towing and avoid
jerky movements. Make sure not to
damage parts in contact with the car while
towing. When towing the vehicle, you
must comply with all specific traffic
regulations and adopt an appropriate
driving behaviour. Do not start the engine
while towing the vehicle.
