Important Safety and General Instructions
This document provides essential information for the correct installation and operation of your Westfalia tow bar. Please read and follow all instructions carefully.
- Adhere to all national guidelines regarding the approval and installation of vehicle accessories.
- Modifications or alterations to the tow bar system are strictly prohibited and will invalidate the operating license.
- Before installation, remove any insulating material or underbody protection from the vehicle's mounting points.
- The tow bar is designed exclusively for towing trailers and carrying loads. Any other use is forbidden.
- Parking Assist Systems: If your vehicle is equipped with parking assistance, the tow bar may interfere with sensors. Adjust the sensor range or disable the system if malfunctions occur. Removable or pivoting ball mounts are less likely to cause issues when not in the operating position.
- Safety: The tow bar is a critical safety component. Installation must be performed by qualified professionals. Incorrect installation can lead to severe accidents.
- The German text of these instructions is the legally binding version.
- Subject to change without prior notice.
Installation Guide
Follow these steps for the installation of the tow bar. Refer to the accompanying diagrams for visual guidance.
Step 1: Vehicle Preparation
Access the vehicle's rear mounting points. This typically involves removing interior trim panels and potentially the bumper cover to expose the chassis mounting locations.
Step 2: Mounting the Tow Bar Brackets
Attach the main tow bar mounting brackets to the vehicle's chassis using the provided hardware. Ensure they are correctly oriented and securely fitted.
Step 3: Attaching the Tow Bar Frame
Position the main tow bar frame onto the mounted brackets. Secure it using the specified bolts, such as the M12 x 40 x 1.75 (8.8) bolts, and associated nuts.
Step 4: Tightening Fasteners and Torque Specifications
All bolts must be tightened to the specified torque values to ensure safety and proper function. Refer to the table below for correct torque settings.
| Bolt Size | Grade | Torque (Nm) |
|---|---|---|
| M6 | 8.8 | 10 |
| M8 | 8.8 | 24 |
| M10 | 8.8 | 48 |
| M12 | 8.8 | 83 |
| M14 | 8.8 | 132 |
| M16 | 8.8 | 200 |
| M8 | 10.9 | 34 |
| M10 | 10.9 | 67 |
| M12 | 10.9 | 117 |
Torque range for general fasteners: 0-220 Nm.
Step 5: Installing and Securing the Tow Ball
Mount the tow ball assembly onto the tow bar receiver. It is critical to ensure the locking mechanism is engaged correctly. A gap of approximately 5 mm between the ball and the locking mechanism indicates proper engagement. A 0 mm gap signifies incorrect installation and must be rectified.
Ball Locking Mechanism Check:
- Correct Lock: A visible gap of approximately 5 mm is required.
- Incorrect Lock: A gap of 0 mm or no visible gap means the ball is not locked correctly.
Step 6: Final Checks and Clearance Requirements
Perform a final check of all fastenings. Ensure the vehicle's clearance requirements, as specified by ECE-R 55 regulations (e.g., minimum 250mm horizontal and 100mm vertical clearance from the vehicle's center line), are met.
Step 7: Tow Ball Operation and Storage
To attach the tow ball, insert it into the receiver and ensure the locking mechanism engages securely. To detach, release the locking lever and remove the ball. When not in use, store the tow ball in its protective bag, typically in the vehicle's trunk.
Technical Data and Declaration of Correct Installation
The D-Value, a measure of the tow bar's strength, is determined according to European Directive ECE-R 55. It is calculated using the formula: D = (T x C) / (T + C) x 0.00981 kN, where T represents the maximum permissible mass of the towing vehicle and C represents the maximum permissible mass of the trailer.
The installer must complete a declaration confirming that the tow bar was fitted correctly according to manufacturer instructions and vehicle specifications, and that the user has been informed about the proper use and maintenance of the tow bar system.
