Towing and tow-starting
!
Make sure that the electric parking brake is
released. If the electric parking brake is faulty,
visit a qualified specialist workshop.
!
Only secure the tow rope or tow bar at the
towing eyes, or the trailer tow hitch, if availa-
ble. You could otherwise damage the vehicle.
!
Observe the following points when towing
with a tow rope:
Secure the tow rope on the same side on
R
both vehicles.
Make sure that the tow rope is not longer
R
than legally permitted. Mark the tow rope in
the middle, e.g. with a white cloth
(11.8 x 11.8 in). This will make other road
users aware that a vehicle is being towed.
Only secure the tow cable to the towing
R
eyes or, if available, to the trailer tow hitch.
Observe the brake lamps of the towing
R
vehicle while driving. Always maintain a dis-
tance a distance so that the tow rope does
not sag.
Do not use steel cables or chains to tow
R
your vehicle. You could otherwise damage
the vehicle.
!
Do not use the trailer tow hitch for recovery
or towing. Do not use the towing eye for
recovery. this could damage the vehicle. If in
doubt, have the vehicle recovered using a
crane.
!
When towing, pull away slowly and
smoothly. Pull the towed vehicle as straight as
possible and not at an acute angle. Excessive
tractive power could damage the vehicles.
When towing, it is preferable to use a rigid tow-
ing bar as opposed to a tow rope. A rigid towing
bar helps to keep the tractive power low.
!
When towing away vehicles with KEYLESS-
GO, use the key instead of the Start/Stop
button. The automatic transmission may oth-
erwise shift to position j when you open the
driver's or front-passenger door, which could
damage the transmission.
!
Do not tow with sling-type equipment. This
could damage the vehicle.
