* NOTE Damage to the vehicle due to incor-
rect use of the trailer hitch
If a trailer hitch is used to recover the vehicle,
the vehicle or the trailer hitch itself may be
damaged in the process.
Use the trailer hitch only for pulling a
#
trailer or attaching approved carrier sys-
tems (e.g. a bicycle rack).
Exception: Since vehicles with a trailer
hitch do not have a fixture for a towing
eye at the rear, towing or tow-starting is
permitted.
When towing or tow-starting with the
#
trailer hitch, observe the information in
the section "Fitting and removing the
towing eye."
