135) 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, comply with the specific
rules of the highway code regarding the
towing device and road conduct. Do
not start the engine whilst the vehicle is
being towed.
WARNING
30) 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 ropes
or other non-rigid devices. Respecting the
above conditions, towing must take place
with two vehicles (one towing, the other
towed) aligned as much as possible along
the same centre line.
