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.
AcuraWatch
TM has following functions.
■The functions which do not requir e switch operations to activate

Driving
Collision Mitigati on Braking SystemTM (CMBSTM)
Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBSTM 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.
■How the system works
1 Collision Mitigation Braking SystemTM (CMBSTM)
Important Safety Reminder
The CMBS
TM is designed to reduce the severity of an
unavoidable collision. It do es not prevent a collision
nor stop the vehicle automati cally. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately acco rding to the driving
conditions.
The CMBS
TM may not activate or may not detect a
vehicle in front of y our vehicle under certain
conditions: 2 CMBS
TM Conditions and Limitations P. 454
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 489
For directions on the prop er handling of the radar
sensor, refer to the following page. 2 Radar Sensor P. 491
When the CMBS
TM activates, it may automatically
apply the brake. It will be canceled when your vehicle
stops or a potential coll ision is not determined.
The radar sensor
is behind the
emblem.
The camera is located
behind the rearview
mirror.
The system starts monitoring the roadway ah ead when your vehicle speed is about
3 mph (5 km/h) and there is a vehicle in front of you.
When to use
The CMBSTM activates when:●The speed difference between your vehicle and a vehicle or pedestrian detected in
front of you becomes about 3 mph (5 km/h) and over with a chance of a collision.
●Your vehicle speed is about 62 mph (100 km/h) or less and the system determines
there is a chance of a collision with:
- Vehicles detected in front of you that ar e stationary, oncoming, or traveling in your
same direction.
- A pedestrian who is detected in front of you.
●Your vehicle speed is above 62 mph (100 km/h), and the system determines there
is a chance of a collision with a vehicle detected in front of you traveling in your
same direction.

The camera in the CMBS
TM is also designed to detect
pedestrians.
However, this pedestrian detection feature may not
activate or may not detect a pedestrian in front of
your vehicle under certain conditions.
Refer to the ones indicating the pedestrian detection
limitations from the list. 2 CMBS

The head-up warning uses a lens located at the front
end of the dashboard.
Do not cover the lens or spill any liquid on it.

The system may automatically shut off and the CMBSTM indicator will come on under
certain conditions. Some examples of th ese conditions are listed below. Other
conditions may reduce some of the CMBS
TM functions.
2 Front Sensor Camera P. 489
■Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).
• Sudden changes between light and dark, such as an entrance or exit of a tunnel.
• There is little contrast between objects and the background.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflected onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Roadway objects or structures are misint erpreted as vehicles and pedestrians.
• Reflections on the interi or of the windshield.
• Driving at night or in a dark condition such as a tunnel.
■Roadway conditions
• Driving on a snowy or wet roadway (obs cured lane marking, vehicle tracks,
reflected lights, road spray, high contrast).
• Driving on curvy, winding, or undulating roads.
• The road is hilly or the vehicle is approaching the crest of a hill.
■CMBSTM Conditions and Limitations1Collision Mitigation Braking SystemTM (CMBSTM)
Have your vehicle checked by a dealer if you find any
unusual behavior of the system (e.g., the warning
message appears too frequently).

• Headlight lenses are dirty or the h eadlights are not properly adjusted.
• The outside of the windshield is blocked by dirt, mud, leaves, wet snow, etc.
• The inside of the windshield is fogged.
• An abnormal tire or wheel condition (wrong sized, varied size or construction,
improperly inflated, compact spare tire
*, etc.).
• When tire chains are installed.
• The vehicle is tilted due to a heavy load or suspension modifications.
• The camera temperature gets too high.
• Driving with the parking brake applied.

• When there is a group of people in front of your vehicle walking together side by
side.
• Surrounding conditions or belongings of the pedestrian alter the pedestrian’s
shape, preventing the system from recogn izing that the person is a pedestrian.
• When the pedestrian is shorte r than about 3.3 feet (1 meter) or taller than about
6.6 feet (2 meters) in height.
• When a pedestrian blends in with the background.
• When a pedestrian is bent over or squatting, or when their hands are raised or
they are running.
• When several pedestrians are walking ahead in a group.
• When the camera cannot correctly identify that a pedestrian is present due to an
unusual shape (holding luggage, body position, size).
■Automatic shutoff
The CMBSTM may automatically shut itself off and the CMBSTM indicator (amber)
comes and stays on when:
• The temperature inside the system is high.
• You drive off-road or on a mountain road, or curved and winding road for an
extended period.
• An abnormal tire condition is detected (wrong tire size, flat tire, etc.).
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
Once the conditions that caused the CMBS
TM to shut off improve or are addressed
(e.g., cleaning), the system comes back on.
Limitations applicable to pedestrian detection only

Driving
Adaptive Cruise Control (ACC) with Low Speed
Follow
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 Low Speed Follow slows y our vehicle by applying the brakes, your
vehicle’s brake lights will illuminate.
1 Adaptive Cruise Control (ACC) with Low Speed Follow
Important Reminder
As with any system, there are limits to ACC with Low
Speed Follow. Use the brake pedal whenever
necessary, and always keep a safe interval between
your vehicle and other vehicles.
ACC with Low Speed Follow can not be activated if
Intelligent Dynamics System setting is Snow.
3WARNING
Improper use of ACC with Low Speed
Follow can lead to a crash.
Use ACC with Low Speed Follow only when
driving on expressways or freeways and in
good weather conditions.
3WARNING
ACC with Low Speed Follow has limited
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 Low Speed Follow: A vehicle is detected ahead
within ACC with Low Speed Follow range – ACC with Low Speed Follow
operates at speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with Low Speed Follow range – ACC with
Low Speed Follow operates at the speed of 25 mph (40 km/h) or above.
■Gear position for ACC with Low Speed Follow: In ( D or (S.
The radar sensor
is behind the
emblem.
The camera is
located behind
the rearview
mirror.
