3 Details for Installing a Floor on the New Zhijie V9

Detail 1: Power must be disconnected before removing the seats Disconnect the negative terminal of the small battery before modification to avoid accidentally triggering the electric seat adjustment during construction and causing a short circuit.

Expert reminder: When choosing a floor, do not only look at the brand ranking; pay more attention to the craftsmanship route. HPL high-temperature pressing (Shangshi Liya) vs film-covered cold pressing (Moche Xia) vs UV printing (Dongmei/Tuya/Zhuangyu) — the wear resistance gap between the three is 3-9 times. For home + business reception, HPL is the first choice; for a moderate budget, film-covered cold pressing is available; for a tight budget, UV printing can be used for the short term.
