uuAcuraWatchTMuAdaptive Cruise Control (ACC) with Low Speed Follow
Driving
Adaptive Cruise Control (ACC) with Low Speed
Follow
Helps maintain a constant vehicle speed a nd 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.
For directions on the prop er handling of the radar
sensor, refer to the following page.
2 Radar Sensor P. 483
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.
The radar sensor is
behind the emblem.
The camera is
located behind the
rearview mirror.

Driving
■There is a vehicle ahead
ACC with Low Speed Follow monitors if a ve hicle ahead of you enters the ACC with
Low Speed Follow range. If a vehicle is detected doing so, the ACC with Low Speed
Follow system maintains or decelerates your vehicle’s set speed in order to keep the
vehicle’s set followi ng-interval from the vehicle ahead.
2To Set or Change Following-interval P. 441
When a vehicle whose speed is slower than
your set speed is detected in front of you, your
vehicle starts to slow down.
■When in Operation1 When in Operation
If the vehicle detected ahead of you slows down
abruptly, or if a nother vehicle is de tected cutting in
front of you, a beeper so unds and a message appears
on the multi-information display, and the head-up

Stopped message appears on the multi-
information display.
When the vehicle ahead of you starts again, if
you press the RES/+/SET/− switch up or
down, or depress the accelerator pedal, ACC
with Low Speed Follow will operate again
within the previously set speed.
If no vehicle is ahead of you before you
resume driving, depressing the accelerator
pedal will resume operation of ACC with Low
Speed Follow within the prior set speed.1 A vehicle detected ahead is within ACC with Low Speed Follow
range and slows to a stop
3WARNING
Exiting a vehicle that has been stopped
while the ACC with Low Speed Follow
system is operating can result in the vehicle
moving without operator control.
A vehicle that moves without operator
control can cause a crash, resulting in
serious injury or death.
Never exit a vehicle when the vehicle is
stopped by ACC with Low Speed Follow.

uuAcuraWatchTMuLane Keeping Assist System (LKAS)
Continued
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 al erts if the vehicle 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 vehicl e control. The system does
not work if you take y our hands off the steering
wheel or fail to steer the vehicle.
The LKAS is convenient when it is used on
expressways or freeways.
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 may not work properly or may work
improperly under the certain conditions: 2 LKAS Conditions and Limitations P. 455
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 481
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 becomes 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.

When the vehicle enters the warning area, the LKAS alerts you with slight steering
wheel vibration as well as a warning display.

uuAcuraWatchTMuTraffic Jam Assist
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 line s as well as any vehicle ahead. Based on
inputs from the radar sensor and camera, th e system can adjust the speed of your
vehicle to maintain a set interval betwee n 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 Control 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 expressways 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 and setting the parking
brake.
