■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.1How 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 driver information interface and head-up
warning
* will appear.
Depress the brake pedal and take direct control of
steering.

To cancel Traffic Jam Assist, you 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 automa tically under the following circumstances.
• The system fails to detect lane lines.
• The vehicle ahead of yo u 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, th e 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 45mph (72km/h).
u When the speed of the vehicle reaches 45mph
(72km/h), Traffic Jam Assist is deactivated and LKAS
is activated instead. Once the speed of the vehicle
drops to under 42mph (68km/ 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 suddenl y changes between light and dark, such
as at the an entrance or exit of a tunnel.
• The road has puddles or the surface of th e road is shiny due to recent rainfall.
• Shadows are cast across the lane lines (e .g., trees, buildings, guardrails, vehicle,
etc.).
• Spray or snow coming off the vehicle ahead.
• Driving at night or in a dark condition such as a tunnel.
■Roadway conditions
Certain features of the road can interfere with proper camera operation. Here are
some examples:
• The lines are not very distinguisha ble from the surface of the road.
• The section of the road has lane res trictions or temporarily marked lanes.
• The lines are faded, removed lines remain visible next to newer lines (duplicate
lines), or the road is marked with tire tracks.

• 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 considerably be cause of an uneven road surface, etc.
• Objects on the road (curb, guard rail, pylons, etc.) are recogn ized as white lines
(or yellow lines).
• The lines appear distorted or they briefl y disappear out of the camera detection
range due to an uneven road surface.

■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 are driving, for example, across a narrow
truss bridge.

Driving
Road Departure Mi tigation System
Alerts and helps to assist you when the system detects a possibility of your vehicle
unintentionally crossing over detected lane 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 st eering torque and alerts
you with rapid vibrations on the steering
wheel, to help you remain within the detected
lane.
2 Customized Features P. 345
As a visual alert, appears on the gauge.
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.
■How the System Works
1Road Departure Mitigation System
Important Safety Reminder
Like all assistance systems, the Road Departure
Mitigation system has limitations.
Over-reliance on the Road Departure Mitigation system
may result in a collision. It is always your responsibility to
keep the vehicle within your driving lane.
The Road Departure Mitigati on 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 condition. It is always your responsibility to
safely operate the vehicle and avoid collisions.
You can read about handling information for the
camera equipped with this system.

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. 539
There are times when you may not notice Road
Departure Mitigation functions due to your operation
of the vehicle, or road surface conditions.
The Road Departure Mitiga tion is not activated for
about 15 seconds after the power system is turned on.
