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
(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 uTraffic Jam Assist
Driving
Traffic Jam Assist
The traffic jam assist system uses a radar se nsor 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 line s 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 betwee n 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.
■How Traffic Jam Assist works
If you are in heavy traffic and Adaptive Cruise Control with Low Speed Follow is
active, the traffic jam assist system, upon de tecting the traffic lane lines and a vehicle
ahead, will apply steering torque to help keep your vehicle in the center of the lane.
The system adjusts the speed of your vehicl e to maintain a set interval between your
vehicle and the one detected ahead.
1 Traffic Jam Assist
3WARNING
Improper reliance on Traffic Jam Assist can
cause a crash resulting in injury or death.
Always maintain full control over your
vehicle even when this system is active. and
only use when on ex pressways or freeways.
Traffic Jam Assist is not an autonomous
driving system:
3WARNING
Failure to securely park vehicle when
stopped using Adaptive Cruise Control with
Low Speed Follow is active can allow the
vehicle to roll away, resulting in an crash
causing injury or death.
Never stop the vehicle and exit it without

uuBraking uCollision Mitigation Braking SystemTM (CMBSTM)
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. 462
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 400
Be careful not to have the radar sensor cover strongly
impacted.
1 How 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.
The radar sensor is
in the front grille.
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 there is a chance of a
collision with an oncoming detected vehicle or a pedestrian in front of you.
