The lifespan of rubber sealing strips for frameless doors is usually only 4-5 years. We carefully press the sealing strip at the edge of the roof to check for loss of elasticity and use a high-pressure water gun to wash the seams of the windows to check for direct water leakage due to aging.

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.

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