- Remove any insulating compound or underbody coating from the vehicle's contact surfaces where the tow bar will be mounted.
- The tow bar is designed for towing trailers and carrying loads only; other uses are forbidden.
- Parking assistance systems may malfunction if obstructed by tow bar parts; adjustments or deactivation may be necessary. This is less likely with removable or pivoting ball mounts when the ball is not in the operating position.
- The tow bar is a safety-critical component and must only be installed by qualified professionals. Improper installation poses a serious accident risk.
- The German text is the binding version.
- Subject to change without notice.
Installation Procedure
The installation involves several steps, including:
- Vehicle Preparation: Accessing the rear of the vehicle, potentially involving bumper removal or modification according to specific dimensions provided for models 321 821 (e.g., cut-out dimensions 55mm, 110mm, 170mm) and 321 822 (e.g., cut-out dimensions 56mm, 215mm, 40mm, 20mm, 70mm, 185mm).
- Mounting the Tow Bar Frame: Attaching the main tow bar frame (labeled '1') to the vehicle's chassis using specified hardware, such as M10x35 bolts and 10.5x25x3 washers, torqued to 55 Nm.
- Attaching the Ball Mount: Connecting the ball mount (labeled '2', '2.1', '2.2') to the tow bar frame using bolts like M12x75 and M16x50 with appropriate washers.
- Torque Specifications: Specific torque values are critical for secure installation:
- M10x35 bolts: 55 Nm
- M12x75 bolts: 95 Nm
- M16x50 bolts: 170 Nm
- Clearance Checks: Ensuring adequate clearance around the tow bar components, as per Directive 94/20/EC, with specific angle and distance requirements related to the vehicle's Gross Vehicle Weight.
- Final Checks: Verifying installation at 0km and 1000km, potentially re-torquing bolts. Consulting the vehicle's manual for interior checks.
The installation requires careful attention to detail and adherence to all specified dimensions and torque values.
