Driving
■How the system works1How the system works
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 system starts monitoring the roadway ahead when your vehicle speed is about 3
mph (5 km/h) or above and will search for a vehicle in front of you. The radar sensor is
behind the emblem.
The camera is
located behind the
rearview mirror.
The CMBS
TM 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 the system determines
there is a chance of a collision with:
- Vehicles detected in front of you that are 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.

■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).

uuAcuraWatchTMuAdaptive Cruise Control (ACC) with Low Speed Follow
Continued
Driving
Adaptive Cruise Control (ACC) with Low Speed
Follow
Helps maintain a constant vehicle speed and 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 ve hicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with Low Speed Follo w slows your 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.
For directions on the prop er handling of the radar
sensor, refer to the following page.
2 Radar Sensor P. 484
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 road and 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.
■Vehicle speed for ACC wi th 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 about 25 mph (40 km/h) or above.
■Gear position for ACC wi th Low Speed Follow: In (D or (S.

Do not use ACC with Low Speed Follow under the
following conditions:
•Driving in continuous stop and go traffic.
•On roads with sharp turns.
•On roads with steep downhill sections, as the set
vehicle speed can be exceeded by coasting. In such
cases, ACC with Low Speed Follow will not apply
the brakes to maintain the set speed.
•On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or faci lities with driv e through access.

uuAcuraWatchTMuLane Keeping Assist System (LKAS)
Driving
Lane Keeping Assist System (LKAS)
Provides steering input to help keep the vehicle in the middle of a detected lane and
provides tactile and visual alerts if the ve hicle is detected drifting out of its lane.1Lane Keeping Assist System (LKAS)
Important Safety Reminders
The LKAS is for your convenience only. It is not a
substitute for your vehicle control. The system does
not work if you take y our hands off the steering
wheel or fail to steer the vehicle.
Do not place objects on the instrument panel.
Objects may reflect on th e windshield and prevent
correct detection of the traffic lanes.
The LKAS only alerts you when lane drift is detected
without a turn signal in use. The LKAS may not detect
all lane markings or lane departures; accuracy will
vary based on weather, speed, and lane marker
condition. It is always your responsibility to safely
operate the vehicle an d avoid collisions.
The LKAS is convenient when it is used on freeways.
The LKAS may not work properly or may work
improperly under the certain conditions:
2 LKAS Conditions and Limitations P. 456
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 482
The LKAS may not function as designed while driving
in frequent stop and go traf fic, or on roads with
sharp curves.
■Steering input assist
When you operate the turn signals to chan ge lanes, the system is suspended, and
resumes after the signals are off.
If you make a lane change without operat ing the turn signals, the LKAS alerts
activate, and torque is applied to the steering.
■Front Sensor
Camera
Monitors the lane
lines
The system applies torque to the steering to keep the vehicle between the left and
right lane lines. The applied torque beco
mes stronger as the vehicle gets closer to
either of the lane lines.■Tactile and visual alerts
Rapid vibrations on the steering
wheel and a warning display alert
you that the vehicle is drifting out
of a detected lane.

uuAcuraWatchTMuTraffic Jam Assist
Continued
Driving
Traffic Jam Assist
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 can adjust the speed of your
vehicle to maintain a set interval between your vehicle and the one detected ahead.
It also can apply steering torque to keep yo ur 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 Contro l with Low Speed Follow is
active, the traffic jam assist system, upon detecting 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 while Adaptive Cruise Control with
Low Speed Follow is active can allow the
vehicle to roll away, resulting in a crash
causing injury or death.
Never stop the vehicle and exit it without
placing it in Park an d setting the parking
brake.

manner conducive to safe driv ing. Traffic Jam Assist
may not function properly when you are driving
through a sharp curve or re peatedly accelerating and
