How a Battery Functions

The CMBS system can detect a possible collision and assist brake operation to help reduce the impact on the vehicle.

Collision Mitigation Braking System Operation Sequence

1. When a speed difference between your vehicle and the vehicle ahead or pedestrian in front of your vehicle is greater than 5 km/h (3 mph) and the system detects a possible collision, the system issues a warning message on the multi information display (MID) and sets an alarm off.
2. When your vehicle is getting close to the vehicle ahead or there is a detected pedestrian ahead of your vehicle, the system issues a warning message on the MID and sets an alarm off to give the warning to the driver that there is a possible collision (First step).
3. When your vehicle gets even closer to the vehicle ahead or pedestrian ahead of your vehicle and the system anticipates a collision, CMBS applies light braking force while issuing the MID warning and setting an alarm off (Second step).
4. When the system determines that a collision is inevitable, the CMBS applies strong brake force while issuing the MID warning and setting an alarm off (Third step).

*1: In normal conditions, the alarm buzzer goes off after the MID warning message appears but they may be issuedat the same time due to driving and weather conditions.

1. The multipurpose camera unit records the number of the brake operations is detect from vehicle ON mode to OFF (LOCK) mode. When the limit for the number of operations is exceeded, “excessive CMBS operation” is judged, the CMBS function is disabled, the warning indicator comes on and DTCs are stored. The limit for the number of operations differs according to the CMBS operation conditions.
2. When the multipurpose camera is malfunctioning (including a temporary function stop), CMBS does not function.
