Switch on the hazard warning flashers, depend-
ing on local regulations. If the car's electrical
system has failed, the car to be towed must be
made identifiable to following vehicles, for
instance by placing a notice or the warning
triangle in the rear window.
With the ignition switched on, engage selector
lever position N, then turn the ignition key back
to position 1.
Towing methods
Do not raise the car at the towing eye or
by body or suspension components, oth-
erwise it could be damaged.<
In some countries, it is prohibited to tow
another vehicle on public roads by means of a
towbar or towrope. Familiarise yourself with the
relevant legislation in the country in question.
With towbar
The towing vehicle must not be lighter
than the towed vehicle, otherwise it may
be unable to keep the towed vehicle reliably
under control.<
The towing eyes of both vehicles should be on
the same side. If it is impossible to avoid attach-
ing the towbar at an angle, note the following:
> Towbar clearance may be restricted when
cornering.
> The towbar will generate lateral forces if it is
attached offset.
Only attach the towbar to the towing
eyes. It could cause damage if attached to
other parts of the car.<
With towrope
Ensure that the towrope is taut when the towing
vehicle moves off.
For towing, use nylon ropes or tapes, as
these will help to avoid sudden tensile
loads. Attach towropes only to the towing eyes.
