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 when a  
collision is deemed unavoidable to help minimize collision severity.

Important Safety Reminder  
The CMBSTM 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.  
How the system works  
When to use  
The CMBSTM may not activate or may not detect a  
vehicle in front of your vehicle under certain  
conditions:  
The camera is  
located behind the  
rearview mirror.  
2 CMBSTM Conditions and Limitations P. 414  
You can read about handling information for the  
camera equipped with this system.  
2 Front Sensor Camera* P. 374  
The radar sensor is  
in the front grille.  
The system starts monitoring the roadway ahead when your vehicle speed is about  
3 mph (5 km/h) and there is a vehicle in front of you.  
The CMBSTM 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.

When the system activates  
1When the system activates  
The camera in the CMBSTM is also designed to detect  
pedestrians.  
The system provides visual and audible alerts of a possible collision, and stops  
if the collision is avoided.  
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.  
u Take appropriate action to prevent a collision (apply the brakes, change  
lanes, etc.)

Audible Alert  
At system’s earliest collision alert stage, you can change the distance (LONG/  
NORMAL/SHORT) between vehicles at which alerts will come on through multi-  
information display setting options.

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

CMBSTM On and Off  
The CMBSTM may automatically shut off, and the  
CMBSTM indicator will come and stay on under certain  
conditions.  
Press this button for about one second to turn  
the system on and off.  
2 CMBSTM Conditions and Limitations P. 414  
When the CMBSTM is off:  
The beeper sounds.  
The CMBSTM indicator in the instrument  
panel comes on.  
A message on the multi-information display  
reminds you that the system is off.  
The CMBSTM is in the previously selected ON or  
OFF setting each time you start the engine.

With Little Chance of a Collision  
The CMBSTM may activate even when you are aware of a vehicle ahead of you, or  
Avoid the following conditions that may cause the  
radar aim to be temporarily out of range and prevent  
the CMBSTM from working properly.  
when there is no vehicle ahead. Some examples of this are:  
A heavy load in the rear or modifications to the  
suspension tilts your vehicle.  
When Passing  
The tire pressures are not correct, the tire sizes are  
incorrect, the tire types are different, and/or the  
tires are not in good condition.  
Your vehicle approaches another vehicle ahead of you and you change lanes to pass.  
At an intersection  
Your vehicle approaches or passes another vehicle that is making a left or right turn.  
For the CMBSTM to work properly:  
Always keep the radar sensor cover clean.  
On a curve  
When driving through curves, your vehicle comes to a point where an oncoming  
vehicle is right in front of you.  
Never use chemical solvents or polishing powder for  
cleaning the sensor cover. Clean it with water or a  
mild detergent.  
Through a low bridge at high speed  
You drive under a low or narrow bridge at high speed.  
Do not put a sticker on the emblem or replace the  
emblem.  
Speed bumps, road work sites, train tracks, roadside objects, etc.  
If you need the radar sensor to be repaired, or  
removed, or the radar sensor cover is strongly  
impacted, turn off the system by pressing the  
CMBSTM off button and take your vehicle to a dealer.  
You drive over speed bumps, steel road plates, etc., or your vehicle approaches train  
tracks or roadside objects [such as a traffic sign and guard rail] on a curve or, when  
parking, stationary vehicles and walls.

CMBSTM Conditions and Limitations  
The system may automatically shut off and the CMBSTM indicator will come on under  
certain conditions. Some examples of these conditions are listed below. Other  
conditions may reduce some of the CMBSTM functions.  
2 Front Sensor Camera* P. 374  
Environmental conditions  
Driving in bad weather (rain, fog, snow, etc.).  
Sudden changes between light and dark, such as an entrance or exit of a tunnel.  
There is little contrast between objects and the background.  
Driving into low sunlight (e.g., at dawn or dusk).  
Strong light is reflected onto the roadway.  
Driving in the shadows of trees, buildings, etc.  
Roadway objects or structures are misinterpreted as vehicles and pedestrians.  
Reflections on the interior of the front windshield.  
Roadway conditions

reflected lights, road spray, high contrast).  
Vehicle conditions  
Headlight lenses are dirty or the headlights are not properly adjusted.  
The outside of the windshield is blocked by dirt, mud, leaves, wet snow, etc.  
The inside of the windshield is fogged.  
An abnormal tire or wheel condition (wrong sized, varied size or construction,  
improperly inflated, compact spare tire, etc.).  
The vehicle is tilted due to a heavy load or suspension modifications.  
The camera temperature gets too hot.

Detection limitations  
A vehicle or pedestrian suddenly crosses in front of you.  
The distance between your vehicle and the vehicle or pedestrian ahead of you is  
too short.  
A vehicle cuts in front of you at a slow speed, and it brakes suddenly.  
When you accelerate rapidly and approach the vehicle or pedestrian ahead of you  
at high speed.  
The vehicle ahead of you is a motorcycle, bicycle, mobility scooter or other small  
vehicle.  
When there are animals in front of your vehicle.  
When you drive on a curved, winding or undulating road that makes it difficult for  
the sensor to properly detect a vehicle in front of you.  
The speed difference between your vehicle and a vehicle in front of you is  
significantly large.  
An oncoming vehicle suddenly comes in front of you.  
Your vehicle abruptly crosses over in front of an oncoming vehicle.  
When driving through a narrow iron bridge.  
Limitations applicable to pedestrian detection only  
When there is a group of people in front of your vehicle walking together side by  
side.  
Surrounding conditions or belongings of the pedestrian alter the pedestrian’s  
shape, preventing the system from recognizing that the person is a pedestrian.  
When the pedestrian is squatting.  
When the pedestrian is shorter than about 3.3 feet (1 meter) or taller than about  
6.6 feet (2 meters) in height.
