14	Lower rear drive module carefully	When lowering the rear drive module check for unobstructed movement of the electrical lines and hoses. Otherwise they may be damaged. When lowering, ensure that there is unobstructed movement between the rear drive module and the vehicle high-voltage battery on the electrical line connecting point (arrow C). Check unobstructed movement with aid of second person when lowering. When lifting rear drive module, ensure that the pull rod of the hand brake cable is routed in the guide in the undercarriage. Before tightening screw/bolts (1, 2) ensure that the parking brake functions properly by actuating the parking brake lever several times.
