Almost all compliant models with hidden door handles have a mechanical emergency pull cable designed inside the car or under the vehicle. If the target country's climate is extreme, we will record a practical emergency door opening tutorial video for you before shipping.

To prevent intermittent failures due to aging of the resistance wire, we will start the engine and set the seat heating/ventilation to maximum for at least 5 minutes, confirming significant temperature changes or airflow output in the cushion and backrest using an infrared thermometer or body sensor.

We use an internationally certified electronic signature platform (such as DocuSign or Adobe Sign). Each signed contract generates a digital certificate with a timestamp and encrypted hash value, which has full legal defense effectiveness in international arbitration courts.
