Lane 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 vehicle is detected drifting out of its lane.

1

Lane 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 your hands off the steering 
wheel or fail to steer the vehicle.

2

Multi-Information Display Warning and 
Information Messages

 P. 122

Do not place objects on the instrument panel. 
Objects may reflect on the 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:

LKAS Conditions and Limitations

 P. 504

You can read about handling information for the 
camera equipped with this system.

2

Front Sensor Camera

 P. 475

The LKAS may not function as designed while driving 
in frequent stop and go traffic, or on roads with 
sharp curves.

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 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.

Lane Keeping Assist System (LKAS)

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.

), aka Electronic 

Stability Control (ESC), System

VSA

®

 helps to stabilize the vehicle during cornering if the vehicle turns more or less 

than what was intended. It also assists in maintaining traction on slippery surfaces. 
It does so by regulating engine and motor output and selectively applying the 
brakes.

When VSA

®

 activates, you may notice that the 

engine and motor do not respond to the 
accelerator. You may also notice some noise 
from the hydraulic system. You will also see 
the indicator blink.

When the VSA

system. While this may not interfere with normal 
driving, have your vehicle checked by a dealer 
immediately.

and does not control the entire braking system. You 
still need to drive and corner at speeds appropriate 
for the conditions and always leave a sufficient 
margin of safety.

Blind spot information System

Driving

Blind spot information System

Is designed to detect vehicles in specified alert zones adjacent to your vehicle, 
particularly in harder to see areas commonly known as “blind spots.”

When the system detects vehicles approaching from behind in adjacent lanes, the 
appropriate indicator comes on for a few seconds, providing assistance when you 
change lanes.

■

How the system works

1

Blind spot information System

Important Safety Reminder

Like all assistance systems, blind spot information 
system has limitations. Over reliance on blind spot 
information system may result in a collision.

The blind spot information system alert indicator may 
not come on under the following conditions:

•

A vehicle does not stay in the alert zone for more 
than two seconds.

•

A vehicle is parked in a side lane.

•

The speed difference between your vehicle and the 
vehicle you are passing is greater than 6 mph (10 
km/h).

•

An object not detected by the radar sensors 
approaches or passes your vehicle.

•

A vehicle running in the adjacent lane is a 
motorcycle or other small vehicle.

WARNING

Failure to visually confirm that it is safe to 
change lanes before doing so may result in 
a crash and serious injury or death.
Do not rely only on the blind spot 
information system when changing lanes.

Always look in your mirrors, to either side 
of your vehicle, and behind you for other 
vehicles before changing lanes.
