Important Notes and Warnings
Please observe the following:
- National guidelines concerning official approval must be followed.
- Any alteration or conversion of the tow bar is prohibited and will result in cancellation of type approval.
- Remove any insulating compound or underseal from the vehicle's mating surfaces where the tow bar will be attached.
- The tow bar is designed for towing trailers with ball couplings and for use with approved load carriers. Any other use is prohibited.
- Parking Assistance Systems: Vehicles equipped with parking assistance systems (e.g., PDC) may experience malfunctions after tow bar installation if the ball bar or coupling is within the sensor detection area. Adjust the sensor detection area or deactivate the system if necessary. This is not expected with detachable or pivoted ball bars if they are removed from their operating position.
- Subject to alteration.
Installation Instructions
Follow these steps carefully for installation:
Step 1: Access Vehicle Undercarriage
Locate the designated mounting points on the vehicle's chassis, typically near the rear bumper area.
Step 2: Prepare Bumper Area
Access the rear bumper, potentially removing trim panels or fasteners.
