What is Collision Mitigation Braking System?
Collision Mitigation Braking System alerts the driver when a potential front-end collision is detected and can even apply the brakes to help slow the vehicle and avoid a collision.
How does CMBS Work?
CMBS uses a front-mounted camera and millimeter-wave radar to monitor traffic conditions ahead. If the vehicle in front suddenly stops, or a pedestrian is detected in the vehicle's path, CMBS alerts the driver in three stages (CMBS may not use all of stages, depending upon the circumstance).
Stage 1: When the initial risk of collision is detected, CMBS issues an audible and visual warning, prompting the driver to take corrective action (this is also part of FCW).
Stage 2: If the driver does not take action and the distance from the object shortens, CMBS continues the audible and visual warnings and applies gentle brake pressure to provide a sensory warning and prompt the driver to take corrective action.
Stage 3: If the driver has no taken action and a collision is imminent, CMBS continues the audible and visual alerts and fully applies the brakes to help the driver avoid the collision. The seatbelt e-pretensioners are also engaged to prepare for a possible collision.
CMBS is like having an extra set of eyes that never blink. By immediately recognizing quickly diminishing following distances, issuing two different warnings, and even applying brakes -- it can help even the most attentive driver avoid a front-end collision. Furthermore, it can help the driver avoid a collision with a pedestrian.
Operating Conditions and Limitations
- Accuracy of the system will vary based on weather, speed and other factors.
- It is always the driver's responsibility to safely operate the vehicle and avoid collisions.
- Never apply a firm or attach any objects to the windshield that could obstruct the CMBS camera's field of vision.
- Scratches, nicks and other damage to the windshield within the CMBS camera's field of vision can cause the system to operate abnormally.
- CMBS may not activate or detect a vehicle under certain conditions. See the vehicle's owner's manual for a complete list of conditions.
Turning CMBS ON/OFF
The driver is able to turn CMBS on or off, based on his/her preferences. To turn CMBS on or off, press the CMBS OFF button located to the left of the steering wheel for about one second.
When CMBS is off:
- The beep sounds
- The CMBS indicator in the instrument panel illuminates
- A message on the multi-information display reminds you that the system is off
- CMBS is in the previously selected state each time you start the engine
