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 al erts if the vehicle 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. 104
Do not place objects on the instrument panel.
Objects may reflect on th e front windshield and
prevent correct detectio n of the traffic lanes.
The LKAS only alerts you when lane drift is detected
without a turn signal in us e. 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. 406
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 381
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 operating the turn signals, the LKAS
alerts activate, and torque is applied to the steering.
■LKAS 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.

stronger.
When the vehicle enters the warning area, the LKAS alerts you with slight steering
wheel vibration as well as a warning display.
■Lane Keep Support Function1 Lane Keeping Assist System (LKAS)
The LKAS may not functi on as designed on while
driving in frequent stop and go traffic, or on roads
with sharp curves.
When it fails to detect lanes, the system will
