uuAcuraWatchTMuAdaptive Cruise Control (ACC) with Low Speed Follow
Driving
■Detection limitations
• A vehicle suddenly crosses in front of you.
• The interval between your vehicle and the vehicle 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 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 or 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 vehicl e 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.

Driving
■Automatic cancellation
The beeper sounds and a me ssage appears on the multi-information display 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 ® or CMBS
TM 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 ACC with Low Speed Follow automatic canc ellation can be also triggered by the
following causes. In these cases, the pa rking brake will be automatically applied.
• The driver’s seat belt is unfasten ed when the vehicle is stationary.
• The vehicle stops for mo re than 10 minutes.
• The engine is turned off.
1Automatic 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)
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 a
substitute for your vehicle control. The system does
not work if you take y our hands off the steering
wheel or fail to steer the vehicle.
2 Multi-Information Display Warning and
Information Messages P. 97
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 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. 482
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 489
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 become s stronger as the vehicle gets closer to
either of the lane lines.

uuAcuraWatchTMuRoad Departure Mitigation (RDM) System
Continued
Driving
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.
2 Customized Features P. 335
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 wh en you turn the steering wheel to avoid
crossing over detected lane markings.
If the system operates several times with out detecting driver response, the system
beeps to alert you.
■How the System Works
1 Road 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 la ne markings or lane or
roadway departures; accu racy will vary based on
weather, speed and lane marker condition. It is
always your responsibilit y to safely operate the
vehicle and avoid collisions.
You can read about handling information for the
camera equipped with this system.
2 Front Sensor Camera P. 489
The RDM system may not wo rk properly or may work
improperly under the certain conditions: 2 RDM Conditions and Limitations P. 487
There are times when you may not notice RDM
functions due to your opera tion of the vehicle, or
road surface conditions.

uuAcuraWatchTMuFront Sensor Camera
Continued
Driving
Front Sensor Camera
The camera, used in systems such as LK AS, RDM, ACC with Low Speed Follow, and
CMBSTM, is designed to detect an object that triggers any of the systems to operate
its 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.
■Camera Location and Handling Tips
1Front Sensor Camera
Never apply a film or attach any objects to the
windshield, the hood, or th e front grille that could
obstruct the camera’s fiel d of vision and cause the
system to operate abnormally.
Scratches, nicks, and othe r damage to the windshield
within the camera’s fiel d of vision can cause the
system to operate abnormall y. If this occurs, we
recommend that you replac e the windshield with a
genuine Acura replacement windshield. Making even
minor repairs within the ca mera’s field of vision or
installing an aftermarke t replacement windshield
may also cause the system to operate abnormally.
After replacing the winds hield, have a dealer
recalibrate the camera. Pr oper 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.
