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.

We will directly check the registration certificate (the big green book) and count the number of changes.

Most basic maintenance reminder lights (like for changing the air conditioning filter) can be manually cleared using a combination of steering wheel buttons or through the engineering mode on the central control screen. We will provide internal guidance manuals for these hidden operations to our B2B clients.
