Collision Mitigation Braking System (CMBS)  
1Collision Mitigation Braking System (CMBS)  
Can assist you when there is a possibility of your vehicle colliding with a vehicle or a  
pedestrian detected in front of yours. The CMBS 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.  
Important Safety Reminder  
The CMBS is designed to reduce the severity of an  
unavoidable collision. It does not prevent collision nor  
stop the vehicle automatically. It is still your  
responsibility to operate the brake pedal and steering  
wheel appropriately according to the driving  
conditions.  
Manual transmission models  
When the CMBS activates, the engine may stop  
automatically.  
Start the engine by normal operation if the engine  
stops.  
2 Starting the Engine P. 514, 517  
The CMBS may not activate or may not detect a  
vehicle in front of your vehicle under certain  
conditions:

How the system works  
1How the system works  
When the CMBS activates, it may automatically apply  
the brake. It will be cancelled when your vehicle stops  
or a potential collision is not determined.  
When to use  
The camera is  
located behind  
the rearview  
mirror.  
The radar sensor is  
in the front grille.  
The system starts monitoring the roadway ahead when your vehicle speed is about  
5 km/h (3 mph) and there is a vehicle in front of you.  
The CMBS activates when:  
The speed difference between your vehicle and a vehicle or pedestrian detected  
in front of you becomes about 5 km/h (3 mph) and over with a chance of a  
collision.  
Your vehicle speed is about 100 km/h (62 mph) or less and the system determines  
there is a chance of a collision with:  
- Vehicles detected in front of you that are stationary, oncoming, or travelling in  
your same direction.  
- A pedestrian who is detected in front of you.  
Your vehicle speed is above 100 km/h (62 mph), and the system determines there  
is a chance of a collision with a vehicle detected in front of you travelling in your  
same direction.

When the system activates  
1How the system works  
The camera in the CMBS 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.  
The system provides visual and audible alerts of a possible collision, and stops  
if the collision is avoided.  
u Take appropriate action to prevent a collision (apply the brakes, change lanes,  
etc.)  
Visual Alerts  
Audible Alert  
Refer to the ones indicating the pedestrian detection  
limitations from the list.

The head-up warning* uses a lens located at the front  
end of the dashboard.  
Do not cover the lens or spill any liquid on it.  
Head-up Warning

At system’s earliest collision alert stage, you can change the distance (Far/Normal/  
Near) between vehicles at which alerts will come on through the driver information  
interface or audio/information screen setting options.

Collision Alert Stages  
The system has three alert stages for a possible collision. However, depending on circumstances, the CMBS may not go through all of the  
stages before initiating the last stage.

CMBS On and Off  
The CMBS may automatically shut off, and the CMBS  
indicator will come and stay on under certain  
conditions.  
Press and hold the button until the beeper  
sounds to switch the system on or off.  
2 CMBS Conditions and Limitations P. 566  
When the CMBS is off:  
The CMBS indicator in the instrument panel  
comes on.  
A message on the driver information  
interface reminds you that the system is off.  
When the CMBS is activated, it will continue to  
operate even if the accelerator pedal is partially  
depressed. However, it will be cancelled if the  
accelerator pedal is deeply depressed.  
The adaptive cruise control (ACC)*, adaptive cruise  
control (ACC) with low speed follow (LSF)*, road  
departure mitigation, vehicle stability assist (VSA)  
system, vehicle stability assist (VSA) OFF, low tyre  
pressure/deflation warning system, collision  
mitigation braking system (CMBS), and parking brake  
and brake system (amber) indicators may come on in  
amber along with a message in the driver information  
interface when you turn the ignition switch to ON  
(w*1 after reconnecting the battery. Drive a short  
distance at more than 20 km/h (12 mph). Each  
indicator should go off. If any do not, have your  
vehicle checked by a dealer.  
The CMBS is turned on every time you start  
the engine, even if you turned it off the last  
time you drove the vehicle.  
*1: Models with the keyless access system have an  
ENGINE START/STOP button instead of an ignition  
switch.

Limitations applicable to pedestrian detection only

side.  
Surrounding conditions or belongings of the pedestrian alter the pedestrian’s  
shape, preventing the system from recognizing that the person is a pedestrian.

in height.  
When a pedestrian blends in with the background.  
When a pedestrian is bent over or squatting, or when their hands are raised or  
they are running.

When the camera cannot correctly identify that a pedestrian is present due to an  
unusual shape (holding luggage, body position, size).  
Automatic shutoff  
CMBS may automatically shut itself off and the CMBS indicator comes and stays on  
when:  
The temperature inside the system is high.  
You drive off-road or on a mountain road, or curved and winding road for an  
extended period.  
An abnormal tyre condition is detected (wrong tyre size, flat tyre, etc.).  
The camera behind the rearview mirror, or the area around the camera, including  
the windscreen, gets dirty.

cleaning), the system comes back on.
