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 vehicle 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. 94
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 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. 426
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 400
When you operate the turn signals to change 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

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.

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 lane is detected,
system will recover automatically.

uuWhen Driving uTraffic Jam Assist
Driving
Traffic Jam Assist
The traffic jam assist system uses a radar se nsor mounted inside the front grille and
a camera mounted to the upper portion of the windshield to detect and monitor left
and right white (yellow) traffic lane line s as well as any vehicle ahead. Based on
inputs from the radar sensor and camera, the system adjusts the speed of your
vehicle to maintain a set interval betwee n your vehicle and the one detected ahead.
It also applies steering torque to keep your vehicle in the center of the detected lane
when you are driving in heavy traffic.
■How Traffic Jam Assist works
If you are in heavy traffic and Adaptive Cruise Control with Low Speed Follow is
active, the traffic jam assist system, upon de tecting the traffic lane lines and a vehicle
ahead, will apply steering torque to help keep your vehicle in the center of the lane.
The system adjusts the speed of your vehicl e to maintain a set interval between your
vehicle and the one detected ahead.
1 Traffic Jam Assist
3WARNING
Improper reliance on Traffic Jam Assist can
cause a crash resulting in injury or death.
Always maintain full control over your
vehicle even when this system is active. and
only use when on ex pressways or freeways.
Traffic Jam Assist is not an autonomous
driving system:
3WARNING
Failure to securely park vehicle when
stopped using Adaptive Cruise Control with
Low Speed Follow is active can allow the
vehicle to roll away, resulting in an crash
causing injury or death.
Never stop the vehicle and exit it without
placing it in Park an d setting the parking
brake.

other factors, Traffic Jam Assist may not function
normally. Always be awar e of your surroundings and
the road conditions, and conduct yourself in a
manner conducive to safe driv ing. Traffic Jam Assist
may not function properly when you are driving
through a sharp curve or re peatedly accelerating and
