Towing
tOWInG : breakdown
towing a vehicle with an
automatic gearbox
With the engine switched off, the trans-
mission is no longer lubricated. It is
preferable to tow this type of vehicle on
a trailer or tow it with the front wheels
off the ground.
u nder exceptional circumstances ,
you may tow the vehicle with all four
wheels on the ground, only going for -
ward, with the gear lever in the n posi-
tion, and for a distance not exceeding
30 miles (50 km).
– Use a rigid towing bar.
If a rope or cable is used
(where the law allows this),
the vehicle being towed
must be able to brake.
– A vehicle must not be towed if it is
not fit to be driven.
– Avoid accelerating or braking
suddenly when towing, as this
may result in damage being
caused to the vehicle.
– When towing a vehicle, it is ad -
visable not to exceed 15 mph
(25 km/h).
