The CMBSTM is designed to alert you when the potential for a 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

1Collision Mitigation Braking SystemTM (CMBSTM)

Important Safety Reminder The CMBSTM is designed to reduce the severity of an unavoidable collision. It does not prevent collisions nor stop the vehicle automatically. It is still your responsibility to operate the brake pedal and steering wheel appropriately according to the driving conditions.

The CMBSTM may not activate or may not detect a vehicle in front of your vehicle under certain conditions:

2 CMBSTM Conditions and Limitations

You can read about handling information for the camera equipped with this system.

2 Front Sensor Camera

For directions on the proper handling of the radar sensor, refer to the following page.

2 Radar Sensor

When the CMBSTM activates, it may automatically apply the brake. It will be canceled when your vehicle stops or a potential collision is not determined.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 radar sensor is behind the emblem.

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.

The camera is located behind the rearview mirror.

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 pedestrians

shape, preventing the system from recognizing that the person is a pedestrian. When the pedestrian is shorter than about 3.3 feet (1 meter) or taller than about

6.6 feet (2 meter) 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 several pedestrians are walking ahead in a group. When the camera cannot correctly identify that a pedestrian is present due to an

unusual shape (holding luggage, body position, size).

Automatic shutoff The CMBSTM may automatically shut itself off and the CMBSTM 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 tire condition is detected (wrong tire size, flat tire, etc.). The camera behind the rearview mirror, or the area around the camera, including

the windshield, gets dirty. Once the conditions that caused the CMBSTM to shut off improve or are addressed (e.g., cleaning), the system comes back on.

There is no vehicle ahead Your vehicle maintains the set speed without having to keep your foot on the brake or accelerator pedal. If there previously was a vehicle detected ahead that kept your vehicle from traveling at the set speed, ACC accelerates your vehicle to the set speed, and then maintains it.

When you depress the accelerator pedal You can temporarily increase the vehicle speed. In this case, there is no audible or visual alerts even if a vehicle is in the ACC range. ACC stays on unless you cancel it. Once you release the accelerator pedal, the system resumes the set speed. There are times when the vehicle speed will decrease when the accelerator pedal is lightly applied.

1When in Operation

Even if the interval between your vehicle and the vehicle detected ahead is short, ACC may start accelerating your vehicle under the following circumstances: The vehicle ahead of you is going at almost the

same speed as, or faster than, your vehicle. A vehicle that cuts in front of you is going faster

than your vehicle, gradually increasing the interval between the vehicles.

You can also set the system to beep when a vehicle in front of you comes in and goes out of the ACC detecting range. Change the ACC Forward Vehicle Detect Beep setting.

Limitations You may need to use the brake to maintain a safe interval when using ACC. Additionally, ACC may not work properly under certain conditions.

Lane Keeping Assist System (LKAS) Provides steering input to help keep the vehicle in the middle of a detected lane and provides visual alert if the vehicle is detected drifting out of its lane.

1Lane Keeping Assist System (LKAS)

Important Safety Reminders The LKAS is for your convenience only. It is not a substitute for your vehicle control. The system does not work if you take your hands off the steering wheel or fail to steer the vehicle.

Do not place objects on the instrument panel. Objects may reflect on the windshield and prevent correct detection of the traffic lanes.

The LKAS only alerts you when lane drift is detected without a turn signal in use. The LKAS may not detect all lane markings or lane departures; accuracy will vary based on weather, speed, and lane marker condition. It is always your responsibility to safely operate the vehicle and avoid collisions.

The LKAS is convenient when it is used on freeways.

The LKAS may not work properly or may work improperly under the certain conditions:

2 LKAS Conditions and Limitations

You can read about handling information for the camera equipped with this system.

2 Front Sensor Camera

The LKAS may not function as designed while driving in frequent stop and go traffic, or on roads with sharp curves.

Steering input assist The system applies torque to the steering to keep the vehicle between the left and right lane lines. The applied torque becomes stronger as the vehicle gets closer to either of the lane lines.

When you operate the turn signals to change lanes, the system is suspended, and resumes after the signals are off. If you make a lane change without operating the turn signals, the LKAS alerts activate, and torque is applied to the steering.

Front Sensor Camera Monitors the lane lines

Tactile and visual alerts Rapid vibrations on the steering wheel and a warning display alert you that the vehicle is drifting out of a detected lane.

uuAcuraWatchTMuLane Keeping Assist System (LKAS)

g

Road Departure Mitigation (RDM) System Alerts and helps to assist you when the system detects a possibility of your vehicle unintentionally crossing over detected lane markings and/or leaving the roadway altogether.

The front camera behind the rearview mirror monitors left and right lane markings (in white or yellow). If your vehicle is getting too close to detected lane markings without a turn signal activated, the system, in addition to a visual alert, applies steering torque and alerts you with rapid vibrations on the steering wheel, to help you remain within the detected lane.

As a visual alert, the Lane Departure message appears on the multi-information display.

If the system determines that its steering input is insufficient to keep your vehicle on the roadway, it may apply braking.

u Braking is applied only when the lane markings are solid continuous lines.

The system cancels assisting operations when you turn the steering wheel to avoid crossing over detected lane markings.

If the system operates several times without detecting driver response, the system beeps to alert you.

How the System Works

1Road Departure Mitigation (RDM) System

Important Safety Reminder Like all assistance systems, the RDM system has limitations. Over-reliance on the RDM system may result in a collision. It is always your responsibility to keep the vehicle within your driving lane.

The RDM system only alerts you when lane drift is detected without a turn signal in use. The RDM system may not detect all lane markings or lane or roadway departures; accuracy will vary based on weather, speed and lane marker condition. It is always your responsibility to safely operate the vehicle and avoid collisions.

You can read about handling information for the camera equipped with this system.

The system becomes ready to start searching for lane markings when all the following conditions are met: The vehicle is traveling between about 45 and 90 mph (72 and 145 km/h). The vehicle is on a straight or slightly curved road. The turn signals are off. The brake pedal is not depressed. The wipers are not in continuous operation. The vehicle is not accelerating or braking, and the steering wheel is not being

turned. The system makes a determination that the driver is not actively accelerating,

braking or steering.

How the System Activates 1How the System Activates

The RDM system may automatically shut off and the indicator comes and stays on.

RDM system function can be impacted when the vehicle is: Not driven within a traffic lane. Driven on the inside edge of a curve, or outside of

a lane. Driven in a narrow lane.

The system may not properly detect lane markings and the position of your vehicle under certain conditions. Some examples of these conditions are listed below.

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 lane lines and the roadway surface. 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. Shadows of adjacent objects are parallel to lane markings. Roadway objects or structures are misinterpreted as lane markers. Reflections on the interior of the windshield. Driving at night or in a dark condition such as a tunnel.

Roadway conditions Driving on a snowy or wet roadway (obscured lane marking, vehicle tracks,

reflected lights, road spray, high contrast). Driving on a road with temporary lane markings. Faint, multiple, or varied lane markings are visible on the roadway due to road

repairs or old lane markings. The roadway has merging, split, or crossing lines (e.g., such as at an intersection

or crosswalk). The lane markings are extremely narrow, wide, or changing. The vehicle in front of you is driving near the lane lines. The road is hilly or the vehicle is approaching the crest of a hill. Driving on rough or unpaved roads, or over bumpy surfaces. When objects on the road (curb, guard rail, pylons, etc.) are recognized as white

lines (or yellow lines). Driving on roads with double lines.

uuAcuraWatchTMuFront Sensor Camera

D rivin

g Front Sensor Camera The camera, used in systems such as LKAS, RDM, ACC, and CMBSTM, is designed to detect an object that triggers any of the systems to operate their functions.

This camera is located behind the rearview mirror.

To help reduce the likelihood that high interior temperatures will cause the cameras sensing system to shut off, when parking, find a shady area or face the front of the vehicle away from the sun. If you use a reflective sun shade, do not allow it to cover the camera housing. Covering the camera can concentrate heat on it.

Camera Location and Handling Tips

1Front Sensor Camera

Never apply a film or attach any objects to the windshield, the hood, or the front grille that could obstruct the cameras field of vision and cause the system to operate abnormally. Scratches, nicks, and other damage to the windshield within the cameras field of vision can cause the system to operate abnormally. If this occurs, we recommend that you replace the windshield with a genuine Acura replacement windshield. Making even minor repairs within the cameras field of vision or installing an aftermarket replacement windshield may also cause the system to operate abnormally. After replacing the windshield, have a dealer recalibrate the camera. Proper calibration of the camera is necessary for the system to operate properly.

Do not place an object on the top of the instrument panel. It may reflect onto the windshield and prevent the system from detecting lane lines properly.

If the Some Driver Assist Systems Cannot Operate: Camera Temperature Too High message appears: Use the climate control system to cool down the

interior and, if necessary, also use defroster mode with the airflow directed towards the camera.

Start driving the vehicle to lower the windshield temperature, which cools down the area around the camera.

If the Some Driver Assist Systems Cannot Operate: Clean Front Windshield message appears: Park your vehicle in a safe place, and clean the

windshield. If the message does not disappear after you have cleaned the windshield and driven for a while, have your vehicle checked by a dealer.
