Quick Reference Guide
AcuraWatchTM (P 396)
AcuraWatch
TM is a driver support system
which employs the use of two distinctly
different kinds of sensors, a radar sensor
located in the front grille and a front sensor
camera mounted to the interior side of the
windshield, behind the rearview mirror.
Front Sensor
Camera The camera is located
behind the rearview
mirror.
Radar Sensor The radar sensor is in
the front grille.
Adaptive Cruise Control
(ACC) with Low Speed
Follow (LSF)
(P 402)
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, wi thout you having to
keep your foot on the brake or the
accelerator.
Lane Keeping Assist
System (LKAS)
(P 421)
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.
Road Departure
Mitigation (RDM) System
(P 416)
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.
Collision Mitigation
Braking System
TM
(CMBS
TM) (P 458)
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 vehicle speed to help
minimize collision severity when a collision is
deemed unavoidable.
Traffic Jam Assist (P 428)
The traffic jam assist system uses a radar
sensor mounted inside the front grille and a
camera mounted to the upper portion of
the windshield to detect and monitor left
and right white (yellow) traffic lane lines as
well as any vehicle ahead. Based on inputs
from the radar sensor and camera, the
system adjusts the speed of your vehicle to
maintain a set interval between your vehicle
and the one detected ahead. It also applies
steering torque to keep your vehicle in the
center of the detected lane when you are
driving in heavy traffic.

uuWhen Driving uAdaptive Cruise Control (ACC) with Low Speed Follow (LSF)
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 detected vehicle comes to a stop, decelerates
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.
3WARNING
Improper use of ACC with 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 limited braking
capability and may not stop your vehicle
in time to avoid a co llision with a vehicle
that quickly stops in front of you.
Always be prepared to apply the brake
pedal if the cond itions 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 25 mph (40 km/h) or above.
■Gear position for ACC with LSF: In ( D. The radar sensor is
in the front grille.
The camera is
located behind
the rearview
mirror.

Driving
The system may automatically shut off and the ACC indicator will come on under
certain conditions. Some examples of thes e conditions are listed below. Other
conditions may reduce some of the ACC functions.
2 Front Sensor Camera P. 400
■Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).
■Roadway conditions
• Driving on a snowy or wet roadway (obs cured lane marking, vehicle tracks,
reflected lights, road spray, high contrast).
■Vehicle conditions
• The outside of the windshield is blocked by dirt, mud, leaves, wet snow, etc.
• An abnormal tire or wheel condition (Wro ng sized, varied size or construction,
improperly inflated, compact spare tire
*, etc.).
• The camera temperature gets too high.
• The parking brake is applied.
• When the front grille is dirty.
• The vehicle is tilted due to a heavy load or suspension modifications.
• When tire chains are installed.
■ACC with LSF Conditions and Limitations1ACC with LSF Conditions and Limitations
The radar sensor for ACC with LSF is shared with the
Collision Mitigati on Braking System
TM (CMBSTM).
2 Collision Mitigation Braking SystemTM
(CMBSTM) P. 458
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 400
Always keep the radar sensor cover clean.
Never use chemical solvents or polishing powder for
cleaning the sensor cover. Clean it with water or a
mild detergent.
Do not put a sticker on the radar sensor cover or
replace the radar sensor cover.
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).

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 dete ct 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.
• When driving through a narrow iron bridge.
• When the vehicle ahead of you brakes suddenly.
• When the vehicle ahead of you has a unique shape.
• When your vehicle or the vehicle ahead of you is driving on one edge of the lane.1ACC with LSF Conditions and Limitations
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:
•The vehicle mounted onto a bump, curb, chock,
embankment, etc.
•You drive the vehicle where the water is deep.

■Automatic ca ncellation
The beeper sounds and a message appears on the multi-information display when
ACC with LSF is automatically canceled. Any of these conditions may cause the ACC
with LSF to automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in the front grille gets dirty.
• The vehicle ahead of yo u cannot be detected.
• An abnormal tire condition is de tected, 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 AC C with LSF range is too close to your
vehicle.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
The ACC with LSF automatic cancellation ca n be also triggered by the following
causes. In these cases, the parking brake will be automatically applied.
• The driver’s seat belt is unfastened when the vehicle is stationary.
• The vehicle stops for more than 10 minutes.
• The power system is turned off.
1Automatic cancellation
Even though ACC with LSF has been automatically
canceled, you can still resu me the prior set speed.
Wait until the condition that caused ACC with LSF to
cancel improves, then press the RES/+/SET/– switch
up.
