Driving
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 Keeping Assist System (LKAS) is active, the
Traffic Jam Assist system, upon detectin g the 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 su rface 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. 653
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. 635
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.

markings.
■How Traffic Jam Assist Works1How Traffic Jam Assist Works
If your vehicle veers too far to the right or the left of
the white (or yellow) traffic lane lines while Traffic
Jam Assist is active, deactivate Traffic Jam Assist and
have your vehicle ch ecked 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

Driving
The system may not detect lane markings and therefore may not keep the vehicle in
the middle of the lane under certain conditions, including the following:
■Environmental conditions
• There is little contrast between lane lines and the roadway surface.
• Driving in bad weather (rain, fog, snow, etc.).
• Driving on a snowy or wet roadway.
• Driving into low sunlight (e.g., at dawn or dusk).
• Shadows of adjacent object s (trees, buildings, guard rails, vehicles, etc.) are
parallel to white (or yellow) lines.
• Sudden changes between light and dark, such as the entrance or exit of a tunnel
or the shadows of trees, buildings, etc.
• Driving at night or in a dark place such as a tunnel (due to low-light conditions,
lane lines or the road surface may not be illuminated).
• When the lane lines or road surface are not visible, such as when the distance to
the vehicle in front of you is extremely short or when at an intersection.
• Strong light is reflec ted onto the roadway.
