3. Components Included

The package includes:

• One (1) Left Side Towing Mirror
• One (1) Right Side Towing Mirror

Additional wiring or specific connectors for certain advanced features (like BSM or full lighting functionality) may not be included if your vehicle's factory harness does not support them. Please refer to the installation section for more details.

4. Installation

Installation of these towing mirrors requires careful attention to detail and electrical connections. Professional installation is highly recommended to ensure proper functionality and avoid damage to your vehicle's electrical system.

General Installation Steps (Consult a professional or detailed vehicle-specific guide):

1. Preparation: Park your vehicle on a level surface, engage the parking brake, and disconnect the negative terminal of the battery.
2. Remove Door Panel: Carefully remove the interior door panel to access the existing mirror mounting bolts and electrical connectors. Use appropriate trim removal tools to prevent damage.
3. Disconnect Old Mirror: Disconnect the electrical harness from the old mirror and unbolt it from the door frame.
4. Install New Mirror: Position the new Sanooer Towing Mirror, connect its electrical harness to the vehicle's wiring, and secure it with the mounting bolts. Ensure all connections are firm and secure.
5. Wiring for Advanced Features: If your vehicle's factory harness does not support all features (e.g., turn signals, puddle lights, BSM), additional wiring may be required. This typically involves splicing wires into the vehicle's existing electrical system. Refer to the provided installation circuit diagram (if applicable) or consult a professional for assistance with these connections.
6. Reassemble Door Panel: Carefully reattach the interior door panel, ensuring all clips and screws are properly secured.
7. Test Functionality: Reconnect the battery and test all mirror functions (power adjustment, heating, turn signals, running lights, backup lights, puddle lights, BSM) before driving.

Note: Some users have reported that certain advanced features (like BSM or full lighting) may not work if the vehicle's factory wiring harness does not include the necessary pins or circuits. This is a limitation of the vehicle's original equipment, not the mirror itself. Professional assistance is crucial for diagnosing and potentially adding these circuits.

5. Operating Instructions

5.1 Power Adjustment (Upper Glass)

Use your vehicle's standard mirror adjustment controls to move the upper flat glass. This allows you to adjust the mirror's perspective angle up, down, left, and right, providing a better view of the rear and sides of your vehicle, especially when towing.

5.2 Manual Adjustment (Convex Glass)

The lower convex glass provides a wider field of view to minimize blind spots. This glass is manually adjustable. Gently push the glass to achieve your desired angle.

5.3 Heated Defrost Function

The heated defrost function helps to clear frost, ice, and condensation from the mirror surface. This feature is typically activated via a button or control within your vehicle's cabin, often integrated with the rear defroster. Ensure this function is enabled in cold or humid conditions for clear visibility.

5.4 Turn Signal, Running Light, and Backup Lamp

These integrated lights enhance safety and visibility:

• Turn Signal Light: Activates when your vehicle's turn signal is engaged, providing a clear indication to other drivers.
• Running Light: Illuminates steadily when your vehicle's running lights or headlights are on.
• Backup Lamp: Activates when your vehicle is in reverse, providing additional illumination for backing up.

5.5 Puddle Light

The puddle light illuminates the ground directly beneath the mirror, assisting with visibility when approaching or exiting your vehicle in low-light conditions. This feature typically activates when the doors are unlocked or opened.

5.6 BSM (Blind Spot Monitoring) Light

If your vehicle is equipped with a Blind Spot Monitoring system and the mirrors are properly wired, the BSM light will illuminate to warn you of vehicles in your blind spot. This feature significantly enhances driving safety.

5.7 Manual Telescoping & Folding

The mirror arms can be manually extended by approximately 3 inches to provide a wider field of view, which is particularly useful when towing wide loads. They can also be manually folded inward for parking in tight spaces or navigating narrow passages.

6. Maintenance

To ensure the longevity and optimal performance of your Sanooer Towing Mirrors, follow these maintenance guidelines:

• Cleaning: Clean the mirror glass and housing regularly with a soft cloth and mild automotive glass cleaner. Avoid abrasive cleaners or harsh chemicals that could damage the finish or coatings.
• Inspection: Periodically inspect the mirrors for any signs of damage, loose components, or frayed wiring. Address any issues promptly.
• Moving Parts: The manual telescoping and folding mechanisms should operate smoothly. If they become stiff, a small amount of silicone lubricant can be applied to the pivot points, avoiding contact with electrical components.
• Electrical Connections: Ensure all electrical connections remain secure and free from corrosion.

7. Troubleshooting

If you encounter issues with your Sanooer Towing Mirrors, consider the following troubleshooting steps:

• Mirror Functions Not Working (e.g., Turn Signal, Puddle Light, BSM):
  • Verify that your vehicle's factory wiring harness supports these specific functions. Many vehicles do not come pre-wired for all advanced mirror features.
  • Check all electrical connections for proper seating and continuity.
  • Consult a professional auto electrician or dealership to confirm vehicle compatibility and potential wiring modifications needed.
• Mirror Glass Vibrates at Speed:
  • Ensure the mirror mounting bolts are securely tightened. Over time, vibrations can loosen these bolts.
  • Check for any loose components within the mirror housing.
  • If vibration persists, professional inspection may be required to identify the cause.
• Heated Function Not Working:
  • Confirm that your vehicle's heated mirror function is activated.
  • Check the fuse associated with the heated mirrors in your vehicle's fuse box.
  • Inspect the wiring for the heating element for any damage or disconnections.
• Power Adjustment Not Working:
  • Check the fuse for the power mirrors in your vehicle.
  • Ensure the electrical connector to the mirror is fully seated.
  • Test the vehicle's mirror adjustment switch to rule out a faulty switch.

For issues not covered here, or if troubleshooting steps do not resolve the problem, please contact Sanooer customer support or a qualified automotive technician.
