8. Risoluzione Dei Problemi

Kick Sensor Malfunction:

Some users have reported that installing the trailer hitch may affect the functionality of the vehicle's kick sensor (for hands-free trunk opening). This can occur due to the hitch's proximity to the sensor's operating area.

• Valutazione: After installation, test your vehicle's kick sensor functionality.
• Risoluzione: If the kick sensor is no longer operational, there may not be a direct fix that maintains both the hitch and sensor functionality simultaneously, as the hitch occupies the sensor's detection zone. Consult your vehicle manufacturer or a professional installer for potential alternative solutions or to confirm if this is an expected outcome with a hitch installed.
