- Ensure that the cable harness is as close to the centre mounting on the tow hitch member as possible. This is important to prevent the cable harness from being caught in the cut-out bumper.

- Route the cable along the underneath of the tow hitch member as illustrated
- Secure the cable with two tie straps.

Installing the connector for fixed tow bars

- Do not tighten the clamps fully yet.

Cargo compartment preparations

- Fold the cargo compartment carpet (1) out of the way
- Turn the clips (2). Fold in the side panels on both sides
- Remove the two covers (3). Remove the screws (4) underneath the covers. Grip the outer edges of the panel (5). Pull the panel inwards towards the centre so that the clips release at the sides. Disconnect the connectors (6) for the side lamps. Remove the panel by pulling it straight upwards so that the clips release from the rear crossmember.

- Remove the wiring (3) for the cargo compartment lighting
- Lift out the sill trim panel.

- Remove the screw (1), the nuts (2) and then the bracket (3) (pull the bracket forwards)
- Lift off the protective cover (4).

- Remove the drainage hose (1) from the battery
