■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
warning above has repeatedly appeared, a warning
buzzer will sound and Traffi c Jam Assist will be
canceled.

■When no vehicle is traveling ahead
If the vehicle detected ahead disappears from
the travel path of your vehicle (for example, it
changes lanes), Traffic Jam Assist will be
deactivated temporarily and your vehicle will
gradually accelerate until it reaches the set
speed, after which it will maintain that speed.1 How Traffic Jam Assist Works
If the vehicle detected ahead suddenly slows down,
or if another vehicle is de tected cutting in front of
yours, a warning buzzer will sound, and a warning in
the multi-information disp lay and head-up warning

uuAcuraWatchTMuRoad Departure Mitigation System
Driving
Road Departure Mitigation System
Alerts and helps to assist you when the system detects a possibility of your vehicle
unintentionally crossing over detected la ne markings and/or leaving the roadway
altogether.
The front camera behind the rearview mirror
monitors left and right lane markings (in white
or yellow). If your vehicle is getting too close to
detected lane markings without a turn signal
activated, the system, in addition to a visual
alert, applies steering torque and alerts you
with rapid vibrations on the steering wheel, to
help you remain within the detected lane.
2 Customized Features P. 302
As a visual alert, the Lane Departure
message appears on the multi-information
display.
If the system determines that its steering input
is insufficient to keep your vehicle on the
roadway, it may apply braking. u Braking is applied only when the lane
markings are solid continuous lines.
The system cancels assisting operations when you turn th e steering wheel to avoid
crossing over detected lane markings.
If the system operates several times without detecting driver response, the system
beeps to alert you.
■How the System Works
1 Road Departure Mitigation System
Important Safety Reminder
Like all assistance systems, the Road Departure
Mitigation system has limitations.
Overreliance on the Road Departure Mitigation
system may result in a collision. It is always your
responsibility to keep the ve hicle within your driving
lane.
The Road Departure Mitigation system only alerts you
when lane drift is detected without a turn signal in
use. The Road Departure Mitigation system may not
detect all lane markings or lane or roadway
departures; accuracy will vary based on weather,
speed and lane marker condi tion. It is always your
responsibility to sa fely operate the vehicle and avoid
collisions.
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 481
The Road Departure Mitigati on system may not work
properly or may work im properly under the certain
conditions:
2 Road Departure Mitigation Conditions and
Limitations P. 473
There are times when you may not notice the Road
Departure Mitigation functions due to your operation
of the vehicle, or road surface conditions.
