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 in the front grille and a front sensor
camera mounted to the interior side of the
windshield, behind the rear view mirror.
The camera is located
behind the rearview
mirror.

Adaptive Cruise Control
(ACC) with Low Speed
Follow (LSF)
(P391)
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.
Road Departure
Mitigation (RDM) System
(P405)
Alerts and helps to assist you when the
system detects a possibility of your vehicle
unintentionally crossing over detected lane
markings.
Lane Keeping Assist
System (LKAS)
(P410)
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) (P437)
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.

trunk lid open. 2 Exhaust Gas Hazard P. 69
To lock the seat-back upri ght, push it backwards until
it locks.
When returning a seat-back to its original position,
push it firmly back. Also, m ake sure all rear shoulder
belts are positioned in front of the seat-back, and the
center shoulder belt is re -positioned in the guide.
Make sure that the folded seat-back does not press
against the front passenger seat, as this can cause the
weight sensors in the front passenger seat to work
improperly. 2 Passenger Front Airbag Off Indicator P. 54
Also make sure all items in the trunk or items
extending through the opening into the rear
seats are properly secured. Loose items can fly
forward if you have to brake hard.
The front seat(s) must be far enough forward so they
do not interfere with the rear seats as they fold

Driving
Collision Mitigation 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. 441
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 389
Be careful not to have the radar sensor cover strongly
impacted.
The system starts monitoring the roadway ahead when your vehicle speed is about 3
mph (5 km/h) and there is a vehicle in front of you. The radar sensor is
in the front grille.
The camera is
located behind the
rearview mirror.
When to use
The CMBSTM activates when:●The speed difference between your vehicl
e 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 there is a chance of a
collision with an oncoming detected ve hicle or a pedestrian in front of you.
1How the system works
Rapid vibrations on the steering wheel alert you
when your vehicle speed is between 19 and 62 mph
(30 and 100 km/h) with an oncoming vehicle
detected in front of you.
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.
