GDW Tow Bar Mounting Instructions for Renault Captur (2013-)
General Advice and Recommendations
General Advice
- Before starting, check the tow bar for transport damage and verify its reference number.
- Read and follow all instructions in the mounting manual precisely.
- Present the tow bar under the vehicle before commencing installation.
- When drilling holes, ensure no electrical or brake wiring is damaged. Remove soundproofing or bitumen layers. Treat drilled holes and chassis parts with an anti-corrosive product.
- If the vehicle has non-standard bumpers (e.g., special series, sport, tuning), consult GDW technical service to confirm compatibility.
- The tow bar is often assembled for storage; disassemble parts before installation.
Guarantee
- To determine the correct towing weight for your vehicle, refer to the Certificate of Conformity (COC) or contact your dealer. Do not exceed the tow bar's specifications.
- The tow bar requires inspection after the first 1,000 km of use and at least annually:
- Check all bolts and retighten if necessary.
- Repair any paint damage.
- Replace any components damaged by external forces or accidents.
- Grease the internal parts of detachable tow bar systems.
Usage Recommendations
- If the towing ball obstructs the license plate or fog light, it must be removed when not in use.
Technical Specifications
Vehicle Specifications
Maximum Trailer Weight
Refer to your vehicle's Certificate of Conformity (COC) or contact your dealer to verify the maximum trailer weight. The D-value and S-value are critical for safe towing.
D-value: Calculated as (Vehicle's maximum towing weight x Vehicle's maximum towing weight) / (Vehicle's Gross Vehicle Weight) x 0.00981. This value must be less than or equal to 7.15 kN for this tow bar.
S-value (Vertical load): Maximum 75 kg.
Maximum Trailer Weight: 1200 kg.
Torque Specifications
The following table provides torque values for various bolt grades and sizes used in the installation. Always use a torque wrench.
Bolt Size | Torque (Nm) for 8.8 Grade | Torque (Nm) for 10.9 Grade | Torque (Nm) for 12.9 Grade |
---|---|---|---|
M6 | 11.3 | 16.5 | 19.3 |
M8 | 27.3 | 40.1 | 46.9 |
M10 | 54.0 | 79.0 | 93.0 |
M12 | 57.0 | 83.0 | 98.0 |
M14 | 93.0 | 137.0 | 160.0 |
M16 | 97.0 | 143.0 | 167.0 |
M18 | 101.0 | 149.0 | 174.0 |
M20 | 148.0 | 218.0 | 255.0 |
M22 | 159.0 | 234.0 | 274.0 |
M24 | 230.0 | 320.0 | 395.0 |
Tools required may include: Torque wrench (TX20), socket wrenches (16, 17, 19), scraper.
Installation Procedure
Step 1: Prepare the Vehicle
Access the rear of the vehicle. Remove any necessary components, such as bumper covers or underbody protection, to gain access to the chassis mounting points. This may involve using a TX20 tool and potentially a scraper.

Step 2: Locate Mounting Points
Identify the designated mounting points on the vehicle's chassis, typically near the rear wheel arches and frame rails. Ensure no wires or brake lines are present near drilling locations.

Step 3: Drill Holes (If Necessary)
If new holes are required, carefully drill them at the marked locations. Treat all drilled holes and surrounding metal with an anti-corrosive agent to prevent rust.

Step 4: Position the Tow Bar Brackets
Attach the main tow bar brackets (often labeled with numbers like 2, 3, 4, 5, 6) to the vehicle's chassis using the provided hardware (bolts, nuts, washers). Ensure correct orientation.

Step 5: Secure the Brackets
Fasten the brackets using the specified bolts and nuts, tightening them to the torque values indicated in the table. Ensure all connections are firm.

Step 6: Attach the Tow Bar Arm
Mount the main tow bar arm (often labeled A or 1) to the installed brackets. Use the appropriate bolts and nuts (e.g., 7, 8, 9, 10) and tighten securely.

Step 7: Final Tightening and Checks
Perform a final check of all bolts and connections. Ensure the tow bar is securely attached and aligned correctly. Refer to the torque specifications for final tightening.

Step 8: Install Tow Ball and Electrical Socket (if applicable)
Attach the tow ball (A) and any associated electrical socket housing. Ensure all locking mechanisms are engaged correctly.

Clearance and Safety
Clearance Requirements
Ensure the following clearance dimensions are maintained as per regulation nr. 55, Appendix VII, diagram 25 (a,b):
- Specific angular clearances (e.g., 30°, 45°, 65°) around the tow ball.
- Maximum and minimum distances for components (e.g., 100mm max, 65mm min, 250mm max).
- Vertical clearance requirements (e.g., 350mm, 420mm).
- Maximum radius for the tow ball (R 14.5 max, R 40 max).
