📖 The Quick Answer
AcuraWatch bundles Collision Mitigation Braking System (CMBS, which is AEB plus FCW), Road Departure Mitigation (LDW plus LKA), Adaptive Cruise Control with Low-Speed Follow, Traffic Sign Recognition, and Auto High-Beam. AcuraWatch 360 (Plus Package on TLX, MDX, and ZDX) adds Blind Spot Information, Rear Cross Traffic Monitor, Front Cross Traffic Warning, and Low-Speed Braking Control.
⚙ How It Works (Sensors and Algorithm)
Hardware is a forward camera behind the windshield and a forward millimeter-wave radar in the grille. AcuraWatch 360 adds four corner radars (front-left, front-right, rear-left, rear-right). The ADAS computer fuses inputs and controls throttle, brake, and electric power steering. Hardware and software are shared with Honda Sensing.
🛡 What It Protects Against
Rear-end collisions, lane departures, drowsy-driver crashes, and (with AcuraWatch 360) intersection T-bones from cross-traffic. IIHS rates TLX, MDX, RDX, and Integra with AcuraWatch as Top Safety Picks.
⚠ Limitations and When It Fails
First-generation AcuraWatch (2016 to 2018) had the same grooved-concrete false-positive issue as Honda Sensing, fixed in MY2019. Like all camera-based systems, it depends on clear lane paint and a clean windshield. After a windshield replacement, static recalibration is required (Acura TSB 19-076).
🚗 Which Vehicles Have It
Every 2020+ Acura has AcuraWatch standard. Lineup includes Integra, TLX, MDX, RDX, and ZDX (electric). AcuraWatch 360 is standard on Advance, Type S, and A-Spec Advance trims.
🔧 Related TSBs and Recalls
Recall 23V-751 (shared with Honda) covers false AEB activation on certain 2018 to 2022 Acura RDX, MDX, and TLX. TSB 19-076 covers camera recalibration after a windshield replacement.
