Collision Mitigation Braking SystemTM (CMBSTM)
Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBSTM is designed to alert you when a
potential collision is determined, as well as to reduce your vehicle speed to help
minimize collision severity when a collision is deemed unavoidable.
■How the system works
1 Collision Mitigation Braking SystemTM (CMBSTM)
Important Safety Reminder
The CMBS
TM is designed to reduce the severity of an
unavoidable collision. It do es not prevent a collision
nor stop the vehicle automati cally. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately acco rding to the driving
conditions.
The CMBS
TM may not activate or may not detect a
vehicle in front of y our vehicle under certain
conditions:
2 CMBS
TM Conditions and Limitations P. 453
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 489
For directions on the prop er handling of the radar
sensor, refer to the following page. 2 Radar Sensor P. 491
When the CMBS
TM activates, it may automatically
apply the brake. It will be canceled when your vehicle
stops or a potential coll ision is not determined.
The system starts monitoring the roadway ah ead when your vehicle speed is about
3 mph (5 km/h) and there is a vehicle in front of you. The radar sensor is
behind the emblem.
The CMBS
TM activates when:●The speed difference between your vehicle and a vehicle or pedestrian
detected in front of you becomes about 3 mph (5 km/h) and over with a chance
of a collision.
●Your vehicle speed is about 62 mph (100 km /h) or less and there is a chance of a
collision with an oncoming detected vehicle or a pedestrian in front of you. The camera is
located behind the
rearview mirror.

At system’s earliest collision alert stage, you can change the distance ( Long/
Normal /Short) between vehicles at which aler ts will come on through multi-
information display or inform ation screen setting options.

1When the system activates
The camera in the CMBS
TM is also designed to detect
pedestrians.
However, this pedestrian detection feature may not
activate or may not detect a pedestrian in front of
your vehicle under certain conditions.
Refer to the ones indicating the pedestrian detection
limitations from the list. 2 CMBS
TM Conditions and Limitations P. 453
The system provides visual and audible alerts of a possible collision, and stops
if the collision is avoided.

lanes, etc.)

The system has three alert stages for a possible collis ion. However, depending on circumstances, the CMBSTM may not go through all of
the stages before initiating the last stage.

Press and hold the button until the beeper
sounds to switch the system on or off.
When the CMBS
TM is off:
• The CMBSTM indicator in the instrument
panel comes on.
• A message on the multi-information display
reminds you that the system is off.
The CMBS
TM is turned on every time you start
the engine, even if you turned it off the last
time you drove the vehicle.
