To cancel Traffic Jam Assist, yo u can do any of the following:
• Press the button.
• Press the LKAS button.
• When the ACC with Low Speed Follow is deactivated.
■When Traffic Jam Assist may au tomatically be suspended when:
The system is temporarily canceled automatically under the following circumstances.
• The system fails to detect lane lines.
• The vehicle ahead of you cannot be detected.
• The steering wheel is turned quickly.
• You fail to steer the vehicle.
• The vehicle in front of you is driving near the lane lines.
• The wipers are set to high.
• The interval between your vehicle and th e one traveling ahead is over 197 feet
(60m).
Once these conditions no longer exist, the Traffic Jam Assist automatically resumes.
■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.
1 When Traffic Jam Assist may automatically be suspended when:
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.

■Environmental conditions
• Bad weather (rain, fog, snow, etc.).
• You are driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflected onto your vehicle or the roadway.
• Brightness in the immediate are suddenly changes between light and dark, such
as at the entrance or exit of a tunnel.
• The road has puddles or the surface of th e road is shiny due to recent rainfall.

Driving
• The roadway has merging, split, or crossing lines (e.g., such as at an intersection
or crosswalk).
• The lane markings are extremely narr ow, wide, or of inconsistent width.
• The lane lines are partly concealed by your vehicle or another vehicle.
• The road is hilly or the vehicle is approaching the crest of a hill.
• The vehicle is shaking cons iderably because of an uneven road surface, etc.
• Objects on the road (curb, guard rail, py lons, etc.) are recognized as white (or
yellow) lines.
• The lines appear distorted or they briefly disappear out of the camera detection
range due to an uneven road surface.
• The road is unpaved, or has a rough or bumpy surface.
• The roads has double lines.
• The surface of the road is slippery due to icy or snowy conditions.
• Sections of the paved road are obscured by puddles or snow.
• The road has ruts.

• The section of the road branches off or merges with another road.
■Certain features of the road can in terfere with proper radar sensor
operation. Here are some examples:
• The road has curves, undulations, slopes, etc.
• The radar beam is reflecting off multiple items that are within close proximity of
your vehicle. This can happen when you ar e driving, for example, across a narrow
truss bridge.

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

properly or may work im properly under the certain

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.

The system may not properly detect lane ma rkings and the position of your vehicle
under certain conditions. Some examples of these conditions are listed below.
■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 lane lines and the roadway surface.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflec ted onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Shadows of adjacent objects are parallel to lane markings.
• Roadway objects or structures are misinterpreted as lane markers.
• Reflections on the interi or of the windshield.
• Driving at night or in a dark condition such as a tunnel.
■Road Departure Mitigation Conditions and Limitations1Road Departure Mitigation On and Off

indicators may come on in amber along with a
message in the multi-information display when you
set the power mode to ON after reconnecting a
battery.
Drive a short distance at more than 12 mph (20
km/h).
Each indicator should go off. If any do not, have your
vehicle checked by a dealer.

Driving
Front Sensor Camera
The camera, used in systems such as Lane Keeping Assist System (LKAS), Road
Departure Mitigation system, Adaptive Cruise Control (ACC) with Low Speed
Follow, Collision Mitigation Braking System
TM (CMBSTM), Traffic Sign Recognition
system, and Traffic Jam Assist is designed to detect an object that triggers any of the
systems to operate its functions.
This camera is located behind the rearview
mirror.
To help reduce the likelihood that high interior
temperatures will cause the camera’s sensing
system to shut off, when parking, find a shady
area or face the front of the vehicle away from
the sun. If you use a reflective sun shade, do
not allow it to cover the camera housing.
Covering the camera can concentrate heat on
it.
■Camera Location and Handling Tips
1 Front Sensor Camera
Never apply a film or attach any objects to the
windshield, the hood, or th e front grille that could
obstruct the camera’s fiel d of vision and cause the
system to operate abnormally.
Scratches, nicks, and othe r damage to the windshield
within the camera’s fiel d of vision can cause the
system to operate abnormall y. If this occurs, we
recommend that you replac e the windshield with a
genuine Acura replacement windshield. Making even
minor repairs within the ca mera’s field of vision or
installing an aftermarke t replacement windshield
may also cause the system to operate abnormally.
After replacing the winds hield, have a dealer
recalibrate the camera. Pr oper calibration of the
camera is necessary for the system to operate
properly.
Do not place an object on the top of the instrument
panel. It may reflect onto the windshield and prevent
the system from detecting lane lines properly.
