• When the brake pedal is depressed.
Conditions for assistive braking cancellation.
• A certain amount of time has passed since activation.
The system may not operate correctly under the following conditions:
■Examples of obstacles the sonar sensors cannot detect
• Obstacles that do not reflect sound waves well, such as people, snow, cloth,
sponges, etc.
• Thin obstacles such as fenc es, bicycles, sign posts, etc.
• Short or small obstacles.
• Obstacles immediately in front of the bumper.
• Obstacles that are not perp endicular to the ground.
• Moving objects or obstacles that suddenly enter the road.

■Low Speed Braking Control System Conditions and Limitations
1Conditions for Cancellation
After Low Speed Braking Control has activated once,
it will not activate again for the same obstacle.
They can be activated again after driving for a certain
distance after last activation.
Low Speed Braking Control ac tivates separately when
moving forward and reversing. (For example, if it
activates when moving forwar d, it can be activated
again immediately if reversing.)
However, if assistive braking has been activated, in
order to activate assistiv e driving power suppression
again, it is necessary to drive for a certain distance to
reset the system.

Adaptive Cruise Control (ACC) with Low Speed Follow
Helps maintain a constant vehicle speed and a set following-interval behind a vehicle
detected ahead of yours and, if the detect ed vehicle comes to a stop, can decelerate
and stop your ve hicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with Low Speed Follo w slows your vehicle by applying the brakes, your
vehicle’s brake lights will illuminate.1 Adaptive Cruise Control (ACC) with Low Speed Follow

uuHonda Sensing ®u Lane Keeping Assist System (LKAS)
Continued
Driving
Lane Keeping Assist System (LKAS)
Provides steering input to help keep the vehicle in the middle of a detected lane and
provides tactile and visual al erts 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 an
autonomous driving system and always requires
driver attention and control. The system does not
work if you take your hands off the steering wheel or
fail to steer the vehicle.
The LKAS is convenient when it is used on
expressways or freeways.
Do not place objects on the instrument panel.
Objects may reflect on th e 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 may not work properly or may work
improperly under the certain conditions:
2 LKAS Conditions and Limitations P. 541
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 568
When you operate the turn signals to chan ge 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.
■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.

uuHonda Sensing ®u Traffic Jam Assist
Continued
Driving
Traffic Jam Assist
The Traffic Jam Assist system uses a camera mounted to the upper portion of the
windshield to detect and monitor left and right white (or yellow) traffic lane lines.
Based on inputs from the camera, the system can apply steering torque to keep your
vehicle in the center of the detected lane.
■How Traffic Jam Assist works
When you are in heavy traffic and Lane Keep ing Assist System (LKAS) is active, the
Traffic Jam Assist system, upon detecting th e traffic lane lines, will apply steering
torque to help keep your vehicle in the center of the lane.
When the driver takes full control of the steering, the steering assist function is
temporarily canceled.
The torque applied to the steering may not be noticeable when the driver has full
control of the steering, or when the surface of the road is rough or uneven.
