4. Required Tools

• 10mm Socket Wrench
• Monkey Wrench (or adjustable wrench)
• Pry tool (for door panel clips)
• Rags (to prevent dropping nuts into door)

5. Setup (Installation)

Professional installation is highly recommended. Follow these steps for proper installation:

1. Remove Door Panel: Carefully remove your vehicle's door panel. This typically involves removing two screws located in the door handle area and then prying off the panel, which is held by clips around its edges. If your vehicle has a manual window crank, you will need to remove it first, which usually involves prying off a retaining clip.
2. Remove Old Mirror: Once the door panel is off, access the bolts holding the old mirror. Use a 10mm socket wrench to remove these bolts.
3. Install New Mirror:
   • Insert the un-mounted bolt into the mounting base on the top corner of the new mirror. Tighten it with a monkey wrench. IMPORTANT: Do not over-tighten to avoid damaging the thread.
   • Tighten the two nuts on the bottom of the mounting base first.
   • Insert the correct-side support bracket (LH or RH) into the upper long bolt as shown and tighten the nut. The bracket is designed to minimize mirror vibration. You may notice the bracket bends inward slightly; this is normal and helps hold the mirror firmly against the door structure.
4. Connect Wiring (if applicable): If your vehicle has power mirror functions, connect the wiring harness. Ensure all connections are secure.
5. Reinstall Door Panel: Replace the door panels, plastic moldings, and trim pieces to finish the installation.

6. Operating Instructions

Your YITAMOTOR towing mirrors are designed for enhanced visibility and convenience. They feature manual adjustments for optimal viewing.

6.1. Manual Mirror Adjustment

The main plane mirror and the lower convex lens can be manually adjusted to provide a wider and clearer view of the area behind your vehicle. Simply push on the mirror glass to achieve the desired angle.

6.2. Manual Telescoping

To extend the mirrors for towing, manually pull the mirror housing away from the vehicle. This extends your line of sight, making it safer to drive, change lanes, and park with a trailer. To retract, push the mirror housing back towards the vehicle.

6.3. Manual Folding

The mirrors can be manually folded inward towards the vehicle. This feature is useful for navigating tight spaces, parking, or going through car washes, helping to avoid obstacles and potential damage.

7. Maintenance

To ensure the longevity and optimal performance of your towing mirrors, regular maintenance is recommended:

• Clean the mirror glass and housing regularly with a mild automotive cleaner and a soft cloth. Avoid abrasive materials that could scratch the surfaces.
• Periodically check all mounting bolts and nuts to ensure they are securely tightened.
• Inspect the mirror housing and glass for any signs of damage. Replace components if necessary.

8. Troubleshooting

If you encounter any issues with your YITAMOTOR towing mirrors, consider the following:

• Vibration: Ensure all mounting bolts and the support bracket are correctly installed and tightened. The support bracket is specifically designed to minimize vibration.
• Difficulty Adjusting: Check for any obstructions or debris that might be hindering the manual adjustment, telescoping, or folding mechanisms.
• Loose Fit: Re-check the tightness of all mounting hardware. If the issue persists, inspect the mounting points on your vehicle for any damage.

For persistent issues or concerns, please refer to the Support section for assistance.
