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

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.

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.

■When a vehicle is traveling ahead
When a vehicle ahead of yours is detected entering the Traffic Jam Assist detection
area, Traffic Jam Assist adjusts the speed of your vehicle to maintain the selected
interval between your vehicle and the one ah ead. It also applies steering torque to
keep your vehicle in the ce nter of the detected lane.
■How Traffic Jam Assist Works1How Traffic Jam Assist Works
If your vehicle veers too far to the right or the left of
the white (yellow) traffic lane lines while Traffic Jam
Assist is active, deactivate Traffic Jam Assist and have
your vehicle checked by a dealer.
In some cases the system cannot properly detect the
traffic lane lines and, as a result, will not provide
steering assistance. 2 Traffic Jam Assist: Conditions and
limitations P. 465
If the driver takes his or her hands off the steering
wheel or does not adequate ly maintain control of
steering, the warning below will appear.
If the driver does not grip the steering wheel after the

■Canceling Traffic Jam Assist1How Traffic Jam Assist Works
If you are traveling slower than the vehicle detected
ahead or a vehicle that is de tected cutting in front of
you and the interval betw een your vehicle and the
detected vehicle gradually increases, your vehicle will
continue to follow that vehicle without emitting any
warning, even if the interv al between the vehicle is
minimal.

You are traveling over 45 mph (72 km/h).
u When the speed of the vehicle reaches 45 mph (72
km/h), Traffic Jam Assist is deactivated and LKAS is
activated instead. Once the speed of the vehicle
drops to under 40 mph (64 km/h), Traffic Jam Assist
is reactivated.
