Only secure the tow rope or tow bar at the
towing eyes. Otherwise, the vehicle could be
damaged.
!
Observe the following points when towing
with a tow rope:
R
Secure the tow rope on the same side on
both vehicles.
R
Ensure that the tow cable is not longer than
legally permitted. Mark the tow cable in the
middle, e.g. with a white cloth (30 x 30 cm).
This will make other road users aware that
the vehicle is being towed.
R
Only secure the tow cable to the towing
eye.
R
Observe the brake lamps of the towing
vehicle while driving. Always maintain a dis-
tance so that the tow rope does not sag.
R
Do not use steel cables or chains to tow
your vehicle. You could otherwise damage
the vehicle.
!
Do not use the towing eyes for recovery pur-
poses as this could damage the vehicle. If in
doubt, recover the vehicle with a crane.
!
When towing, pull away slowly and
smoothly. If the tractive power is too high, the
vehicles could be damaged.

The vehicle can be towed a maximum of
30 miles (50km). The towing speed of 30 mph
(50km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the front axle must be raised
or the entire vehicle raised and transported.
