Conditions for assistive driving power suppression.
• When the accelerator is no longer depressed.
• When the accelerator is depresse d for approximately four seconds.
• When the brake pedal is depressed.
• When the steering wheel is tu rned and a collision avoided.
Conditions for assistive braking cancellation.
• A certain amount of time ha s passed since activation.
The system may not operate correct ly in the following conditions:
■Examples of obstacles the sonar sensor cannot detect
• Obstacles that do not refl ect sound waves well, such as people, snow, cloth,
sponges, etc.
• Thin obstacles such as fences, bicycles, sign posts, etc.
• Short or small obstacles.
• Obstacles immediately in front of the bumper.
• Moving objects or obstacles that suddenly enter the road.
• Obstacles that are not pe rpendicular to the ground.
■Conditions for Cancellation
■Low Speed Braking Control System Conditions and
Limitations
1 Conditions 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.

Increase or decrease the vehicle speed using the RES/+/SET/– switch on the steering
wheel.
• Each time you press the RES/+ /SET/– switch up or down, the vehicle speed is
increased or decreased by about 1 mph or 1 km/h accordingly.
• If you keep the RES/+/SET/– switch pressed up or down, the vehicle speed
increases or decreases by about 5 mph or 5 km/h accordingly.
■To Adjust the Vehicle Speed1 To Adjust the Vehicle Speed
If a vehicle detected ahead is going at a speed slower
than your increased set speed, ACC with Low Speed
Follow may not accelerate y our vehicle. This is to
maintain the set interval between your vehicle and
the vehicle ahead.
When you depress the accelerator pedal and then
press down and release the RES/+/SET/– switch, the
current speed of the vehicle is set.

■Automatic cancellation
The beeper sounds and a message appears on the driver information interface when
ACC with Low Speed Follow is automaticall y canceled. Any of these conditions may
cause the ACC with Low Speed Fo llow to automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor behind the emblem gets dirty.
• The vehicle ahead of you cannot be detected.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA ®, CMBS
TM or Low Speed Braking Control is activated.
• When the ABS or VSA ® system indicator comes on.
• When the vehicle is stopped on a very steep slope.
• When you manually apply the parking brake.
• When the detected vehicle within the ACC with Low Speed Follow range is too
close to your vehicle.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
• When the Maximum Load Limit is exceeded.
• When passing through an enclos ed space, such as tunnel.
• The vehicle has repeatedly applied the brakes to maintain the set speed (for
example, you are descending a long slope).
1 Automatic cancellation
Even though ACC with Low Speed Follow has been
automatically canceled, you can still resume the prior
set speed. Wait until the condition that caused ACC
with Low Speed Follow to cancel improves, then
press the RES/+/SET/– switch up or down.

uuAcuraWatchTMuLane Keeping Assist System (LKAS)
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 alerts if the ve hicle 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 vehicl e control. The system does
not work if you take y our hands off the steering
wheel or fail to steer the vehicle.
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 an d 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 P. 520
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 547
The LKAS may not function as designed while driving
in frequent stop and go traf fic, or on roads with
sharp curves.
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 operat ing 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.
