Main Menu Table Of Contents Collision Mitigation Brake System (CMBS) Radar Sensor BOLTS (Do not tamper) Do not allow anything to impact the radar sensor or the emblem. If either of these parts receives a strong impact, turn off the system by pressing the CMBS off switch, and have your vehicle checked by a dealer. If the front grille ever needs to be repaired, consult a dealer first. If the front emblem or the radar sensor ever needs to be removed, take your vehicle to a dealer. EMBLEM The radar sensor is located behind the Acura emblem in the front grille. If the emblem is covered with mud, dirt, dead leaves, wet snow, etc., or if you put a sticker on it, the CMBS will automatically shut off, and the CMBS indicator on the instrument panel will come on. You will also see a CHECK CMBS RADAR SENSOR message on the multi-information display for about 5 seconds. Always keep the emblem clean. If it gets dirty, clean it with water or a mild detergent. Never use chemical solvents or polishing powder. There are three bolts on the sides of the radar sensor. Do not tamper with these bolts, or you may cause the system to malfunction. 362 2008 RL
