uuWhen Driving uLane Keeping Assist System (LKAS)
Driving
Lane Keeping Assist System (LKAS)
Provides steering input to help keep the vehicle in the middle of a detected lane and 
provides tactile and visual alerts if the ve hicle is detected drifting out of its lane.1Lane Keeping Assist System (LKAS)
Important Safety Reminders
The LKAS is for your convenience only. It is not a 
substitute for your vehicl e control. The system does 
not work if you take y our hands off the steering 
wheel or fail to steer the vehicle.
2 Multi-Information Display Warning and 
Information Messages  P. 115
Do not place objects on the instrument panel. 
Objects may reflect on th e windshield and prevent 
correct detection of the traffic lanes.
The LKAS only alerts you when lane drift is detected 
without a turn signal in use.  The LKAS 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 an d avoid collisions.
The LKAS is convenient when it is used on freeways.
The LKAS may not work  properly or may work 
improperly under the certain conditions: 2 LKAS Conditions and Limitations  P. 516
The LKAS may not function  as designed while driving 
in frequent stop and go traf fic, or on roads with 
sharp curves.
You can read about handling information for the 
camera equipped with this system. 2 Front Sensor Camera  P. 487
When you operate the turn signals to chan ge lanes, the system is suspended, and 
resumes after the signals are off.
If you make a lane change without operat ing the turn signals, the LKAS alerts 
activate, and torque is  applied to the steering.
■Front Sensor 
Camera
Monitors the lane 
lines■Tactile and visual alerts
Rapid vibrations on the steering 
wheel and a warning display alert 
you that the vehicle is drifting out 
of a detected lane.
■Steering input assist
The system applies torque to the steering to  keep the vehicle between the left and 
right lane lines. The applied torque becomes stronger as the vehicle gets closer to 
either of the lane lines.
