uuHonda Sensing® uCollision 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 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.

When to use

The camera is located behind the rearview mirror.

The radar sensor is at the lower part of the front bumper.

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 the system determines there is a chance of a collision with:

Vehicles detected in front of you that are stationary, oncoming, or traveling in your same direction.

A pedestrian who is detected in front of you.

Your vehicle speed is above 62 mph (100 km/h), and the system determines there is a chance of a collision with a vehicle detected in front of you traveling in your same direction.

uuHonda Sensing® uAdaptive Cruise Control (ACC) with Low Speed Follow

To Set the Vehicle Speed

When driving at about 25 mph (40 km/h) or above: Take your foot off the pedal and press the SET/– button when you reach the desired speed. The moment you release the button, the set speed is fixed, and ACC with Low Speed Follow begins. When driving slower than about 25 mph (40 km/h): If the vehicle is moving and the brake pedal is not depressed, pressing the button fixes the set speed to about 25 mph (40 km/h) regardless of current vehicle speed. If the vehicle is stationary, you can set the vehicle speed even with the brake pedal depressed.

When ACC with Low Speed Follow starts operating, the vehicle icon, interval bars and set speed appear on the driver information interface.

When you use ACC with Low Speed Follow, Straight Driving Assist (a feature of the Electric Power Steering system) is activated.

By enabling the steering system to automatically compensate for natural steering pull, Straight Driving Assist makes it easier for you to keep your vehicle in a straight line.

uuHonda Sensing® uAdaptive Cruise Control (ACC) with Low Speed Follow

When in Operation

There is a vehicle ahead

ACC with Low Speed Follow monitors if a vehicle ahead of you enters the ACC with Low Speed Follow range. If a vehicle is detected doing so, the ACC with Low Speed Follow system maintains or decelerates your vehicle’s set speed in order to keep the vehicle’s set following interval from the vehicle ahead.

2 To Set or Change Following-interval P. 482

When a vehicle whose speed is slower than your set speed is detected in front of you, your vehicle starts to slow down.

Continued 475

uuHonda Sensing® uAdaptive Cruise Control (ACC) with Low Speed Follow

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 with Low Speed Follow accelerates your vehicle to the set speed, and then maintains it.

You can temporarily increase the vehicle speed. In this case, there is no audible or visual alert even if a vehicle is in the ACC with Low Speed Follow range.

ACC with Low Speed Follow stays on unless you cancel it. Once you release the accelerator pedal, the system resumes an appropriate speed for keeping the following interval while a vehicle ahead is within the ACC with Low Speed Follow range.

476

uuHonda Sensing® uAdaptive Cruise Control (ACC) with Low Speed Follow

uuHonda Sensing® uRoad 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.

How the System Works

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.

2 Customized Features P. 352

As a visual alert, the Lane Departure message appears on the driver information interface.

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.

uuHonda Sensing®uRoad Departure Mitigation (RDM) System

  How the System Activates 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 high speed operation.

uuHonda Sensing® uTraffic Sign Recognition System

Reminds you of road sign information, such as the current speed limit, your vehicle has just passed through, showing it on the driver information interface and the head-up display*.

  How the System Works When the camera located behind the rearview mirror captures traffic signs while driving, the system displays the ones that are recognized as designated for your

vehicle. The sign icon will be displayed until the vehicle reaches a predetermined

time and distance.

The sign icon also may switch to another one or disappear when:

• The other designated limit is detected.

• You make a turn with a turn signal at an intersection.

uuHonda Sensing® uFront Sensor Camera

The camera, used in systems such as LKAS, RDM, ACC with Low Speed Follow, CMBSTM and traffic sign recognition system, 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 camera’s 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.
