Main Menu Table Of Contents Collision Mitigation Brake System (CMBS) Overview If equipped The collision mitigation brake system (CMBS) can assist you when there is a possibility of your vehicle hitting the vehicle in front of you. It is designed to reduce the speed of your vehicle before an unavoidable collision occurs and, if possible, to alert you to a potential collision while there is time to prevent it. Here is a brief description of what the CMBS can do: When your speed is above 10 mph (15 km/h), the CMBS radar sensor in the front grille can sense a vehicle ahead of you. When your vehicle gets too close to the vehicle ahead of you, the system may activate a warning beep, causing automatic application of the brakes, and causing the e-pretensioners to tighten the front seat belts (see page 24 ). The CMBS does not activate if the speed difference between your vehicles is less than 10 mph (15 km/h). CMBS may also not activate if you turn the steering wheel to avoid the collision. When the CMBS activates, the brake lights also come on. RADAR SENSOR BRAKE ACTUATOR SEAT BELT E-PRETENSIONER Driving The CMBS consists of a radar sensor in the front grille, a brake actuator in the engine compartment, an indicator on the instrument panel, seat belt e-pretensioners on the front seats, and an on/off switch on the dashboard. 2008 RL 361
