Traffic Jam Assist*
The Traffic Jam Assist system uses a came ra mounted to the upper portion of the
windshield to detect and monitor left and right white (or yellow) traffic lane lines.
Based on inputs from the camera, the system can apply steering torque to keep your
vehicle in the center of the detected lane.
■How Traffic Jam Assist works
When you are in heavy traffic and Lane Keep ing Assist System (LKAS) is active, the
Traffic Jam Assist system, upon detecting th e traffic lane lines, will apply steering
torque to help keep your vehicle in the center of the lane.
When the driver takes full control of the steering, the steering assist function is
temporarily canceled.
The torque applied to the steering may not be noticeable when the driver has full
control of the steering, or when the surface of the road is rough or uneven.

Important Safety Reminders
Traffic Jam Assist is for your convenience only. It is
not an autonomous driving system and always
requires driver at tention and control. The system
does not work if you take y our hands off the steering
wheel or fail to steer the vehicle.
Traffic Jam Assist is conven ient when it is used on
expressways or freeways.
You can read about handling information for the
camera equipped with this system. 2 Front Wide View Camera P. 581
The Traffic Jam Assist only alerts you when lane drift
is detected without a turn signal in use. The Traffic
Jam Assist 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 and avoid collisions.
Traffic Jam Assist may not work properly under
certain conditions: 2 Traffic Jam Assist Conditions and
Limitations P. 562
Front Wide View Camera
When you use the turn signal to indica te a lane change, Traffic Jam Assist is
temporarily deactivated. It is reactivated once the vehicle is traveling in the
center of the lane and the system has detected the traffic lane lines.
