Traffic Jam Assist  
The Traffic Jam Assist system uses a camera 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.  
1Traffic Jam Assist  
Important Safety Reminders  
Traffic Jam Assist is for your convenience only. It is  
not an autonomous driving system and always  
requires driver attention and control. The system  
does not work if you take your hands off the steering  
wheel or fail to steer the vehicle.  
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 detecting the traffic lane lines, will apply steering  
torque to help keep your vehicle in the center of the lane.  
Traffic Jam Assist is convenient when it is used on  
expressways or freeways.  
You can read about handling information for the  
camera equipped with this system.  
Front Sensor Camera  
Detects left and right white  
(or yellow) traffic lane lines  
2 Front Sensor Camera P. 542  
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. 532  
When you use the turn signal to indicate 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.  
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.

1How Traffic Jam Assist Works  
How 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 checked by a dealer.  
Keep your vehicle near the center of the lane  
while driving.  
Green lines  
u The LKAS indicator changes from white  
to green, and white lines change to  
green once the system starts operating  
after detecting the left and right lane  
In some cases the system cannot properly detect the  
traffic lane lines and, as a result, will not provide  
steering assistance.
