released. If the electric parking brake is faulty,
visit a qualified specialist workshop.

Secure the tow rope or tow bar to the towing
eye only. Otherwise, the vehicle could

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.

Shift the automatic transmission to N and
do not open the driver's or front passenger's
door during towing. The automatic transmis-
sion may otherwise shift to position P, which
could damage the transmission.

The vehicle can be towed a maximum of
30 miles (50km). The towing speed of 30 mph
(50 km/h) must not be exceeded.
If the vehicle has to be towed more than
30 miles (50km), the entire vehicle must be
raised and transported.
It is better to have the vehicle transported than
to have it towed away.
If the vehicle has suffered transmission damage,
have it transported on a transporter or trailer.
The automatic transmission must be in position
N when the vehicle is being towed.
If the automatic transmission cannot be shifted
to position N, have the vehicle transported on a
transporter or trailer.
