Quick Reference Guide
AcuraWatchTM
AcuraWatchTM is a driver support system
which employs the use of two distinctly
different kinds of sensors, a radar sensor
located behind the emblem and a front
sensor camera mounted to the interior side
of the windshield, behind the rearview
mirror.
The camera is located
behind the rearview
mirror.
The radar sensor is
behind the emblem.
Front Sensor
Camera
Radar Sensor
Adaptive Cruise Control
(ACC) with Low Speed
Follow (LSF)
(P492)
Helps maintain a constant vehicle speed and
a set following-interval behind a vehicle
detected ahead of yours and, if the detected
vehicle comes to a stop, can decelerate and
stop your vehicle, without you having to
keep your foot on the brake or the
accelerator.
Road Departure
Mitigation (RDM) System
(P507)
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.
Lane Keeping Assist
System (LKAS)
(P512)
Provides steering input to help keep the
vehicle in the middle of a detected lane and
provides tactile and visual alerts if the
vehicle is detected drifting out of its lane.
Collision Mitigation
Braking System
TM
(CMBS
TM) (P539)
Can assist you when there is a possibility of
your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The
CMBS
TM is designed to alert you when a
potential collision is determined, as well as
to reduce your vehi cle speed to help
minimize collision severity when a collision is
deemed unavoidable.

Driving
Adaptive Cruise Control (ACC) with Low Speed
Follow (LSF)
Helps maintain a constant vehicle speed an d 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 vehicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with LSF slows your vehicle by applying the brakes, your vehicle’s brake
lights will illuminate.
1 Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)
Important Reminder
As with any system, there are limits to ACC with LSF.
Use the brake pedal whenever necessary, and always
keep a safe interval between your vehicle and other
vehicles.
Be careful not to severely impact the radar sensor
cover.
3WARNING
Improper use of ACC wi th LSF can lead to a
crash.
Use ACC with LSF only when driving on
expressways or freeways and in good
weather conditions.
3WARNING
ACC with LSF has limite d braking capability
and may not stop your vehicle in time to
avoid a collision with a vehicle that quickly
stops in front of you.
Always be prepared to apply the brake
pedal if the conditions require.
When to use
■Vehicle speed for ACC with LSF: A vehicle is detected ahead within ACC with
LSF range – ACC with LSF operates at speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with LSF range – ACC with LSF operates at
the speed of about 25 mph (40 km/h) or above.
■Gear position for ACC with LSF: In ( D or (S. The radar sensor is
behind the emblem.
The camera is
located behind the
rearview mirror.

If you need the radar sensor to be repaired, or
removed, or the radar se nsor cover is strongly
impacted, turn off the system by pressing the MAIN
button and take your vehicle to a dealer.
Have your vehicle checked by a dealer if you find any
unusual behavior of the system (e.g., the warning
message appears too frequently).
If the front of the vehicle is impacted in any of the
following situations, the ra dar sensor may not work
properly. Have your vehi cle checked by a dealer:

■Automatic cancellation
The beeper sounds and a message app ears on the MID when ACC with LSF is
automatically canceled. Any of these co nditions may cause the ACC with LSF 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 LSF range is too close to your
vehicle.
• When a detected vehicle goes out of th e ACC with LSF range while your vehicle
is stationary.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
The ACC with LSF automatic cancellation can be also triggered by the following
causes. In these cases, the electric park ing brake will be automatically applied.
• The driver’s seat belt is unfastened when the vehicl e is stationary.
• The vehicle stops for mo re than 10 minutes.
