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 radar sensor cover. 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 radar sensor cover or the radar sensor ever needs to be removed, take your vehicle to a dealer. RADAR SENSOR COVER The radar sensor is located under the Acura emblem in the front grille. If the radar sensor cover 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 radar sensor cover 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. 420 2009 RL
