Installation Steps
- Prepare the Mirror: Ensure your vehicle's original side mirrors are clean and free of debris.
- Align the Extension: Take one towing mirror extension and align it with your vehicle's existing side mirror. The extension is designed to fit snugly over the original mirror housing.
- Secure the Clips: Carefully position the top clips of the towing mirror extension over the top edge of the original mirror housing.
- Engage Bottom Clips: Gently push the extension downwards until the bottom clips securely engage with the lower edge of the original mirror. Ensure all clips are firmly attached to prevent any movement or vibration during operation.

4. Operating Instructions
Mirror Adjustment
The mirror glass on the towing extensions is adjusted manually. Carefully move the mirror surface to achieve the desired viewing angle for optimal visibility while towing.
Folding Mirrors
The towing mirror extensions are designed to allow the vehicle's original mirrors to be folded without needing to remove the extensions, providing convenience when parking or navigating tight spaces.
Mirror Type
The towing mirror extensions feature a convex lens. This type of lens provides a wider field of view, which is beneficial for towing. Please note that objects viewed in convex mirrors are closer than they appear.
5. Maintenance
Cleaning
To clean the towing mirrors, use a soft cloth and a mild automotive glass cleaner. Avoid abrasive cleaners, harsh chemicals, or materials that could scratch the mirror surface or the textured black housing.
Storage
When the towing mirrors are not in use, it is recommended to remove them from your vehicle and store them in the provided storage bag. This will protect them from scratches, dust, and potential damage, prolonging their lifespan.
6. Troubleshooting
Mirror Instability or Vibration
If the towing mirrors appear loose or vibrate excessively during driving, ensure all clips are securely fastened to the vehicle's original mirrors. Re-attach the extensions if necessary, ensuring a firm fit. Check for any obstructions that might prevent proper seating.
Limited Visibility
Adjust the mirror glass manually to optimize your field of view. Remember that convex mirrors make objects appear farther away than they actually are. If visibility remains insufficient for your specific towing setup, consider consulting a professional for alternative solutions or ensuring your trailer is properly aligned.
