Please note: Use cable ties (Q) to secure the wires under the instru-
ment cluster to the fuse holder and BCM control unit, such that they
cannot become detached. This prevents them from coming into
contact with any other components located under the instrument
cluster (knee airbag, foot pedals, steering column, etc. for left-hand
drive vehicles, and the passenger-side storage compartment and
moving part of the heater (flap) for right-hand drive vehicles).
Under no circumstances should the operation of the knee airbag, foot
pedals or any other components located underneath the instrument
cluster be impaired.
At the same time, it must still be possible to disconnect the fuse
holder, as well as the connectors for the BCM control unit.
Instructions for vehicles set up/not set up to accommodate
a tow bar
- 35 -
- For vehicles not set up to accommodate a tow bar, plug the connector on the wiring harness
(F) into the corresponding connector on the switch in the luggage compartment side pan-
elling (see detail); for vehicles set up to accommodate a tow bar, you may need to plug the
connector into the vehicle's existing electrical installation.
Refit all the components that you removed earlier and tighten each of the connections to
the specified tightening torques.
Connect the vehicle battery and carry out all the steps for disconnecting and reconnecting
the battery.
Activating the tow bar
Carry out guided troubleshooting.
- Activate the "Software version management (SVM)" function. In this menu, select function 3,
known as the "Conversion/retrofitting solution" (see fig. 37).
- Enter the five-digit task code (can be found in the spare parts catalogue (ETKA)) and confirm.
- End the diagnostics in the usual manner.
- Check that the ball hitch swivels in and out correctly (fig. 36). If the ball hitch hits the edge
of the opening in the bumper when it swivels out, trim the opening so that the ball hitch is
able to swivel out unobstructed.
- Check that the rear view camera (if fitted) is functioning correctly.
Use a trailer or tester to check that the tow bar is working correctly.
If using a tester, it is recommended that this tester should be able to
simulate the actual electrical load that would be applied when a
trailer is coupled.
