Continued
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 Driver Information Interface Warning and
Information Messages P. 104
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 and 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. 538
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 546
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.
■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.

Driving
Provides assistance to keep the vehicle in the center of the lane. When the vehicle
nears a white or yellow line, steering force of the electric power steering will become
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 function as designed while driving
in frequent stop and go traf fic, or on roads with
sharp curves.
When it fails to detect lanes, the system will
temporarily be canceled. When a lane is detected, the
system will recover automatically.
