Interior rearview mirror (located above the windshield; flat mirror for viewing the rear); exterior rearview mirrors (on the left/right front doors or A-pillars; typically convex or dual-curvature mirrors for viewing the side and rear); downward-view mirrors (found on some commercial or specialized vehicles for viewing the ground or wheel area).
Electric adjustment (multi-way with memory function); automatic anti-glare (electrochromic or prismatic); heating for defogging/defrosting (electric heating elements); electric folding (to prevent scraping/for parking).
Smart assistance functions: Blind Spot Detection (BSD) (radar + mirror-integrated warning light); lane-change assistance; automatic downward tilt when reversing (tilting exterior mirrors down when in Reverse); streaming media rearview mirror (rear-facing camera + interior display, replacing or supplementing the optical mirror).
Cutting-edge types: Electronic rearview mirror/Camera Monitor System (CMS) (no physical glass; uses cameras and displays to generate images; complies with the new national standard GB 15084-2022; reduces wind resistance but relies on system stability).
