Steering assist function

When the system determines that the 
vehicle might depart from its lane or 
course

*

, the system provides assis-

tance as necessary by operating the 
steering wheel in small amounts for a 
short period of time to keep the vehicle 
in its lane.

When the system determines that the vehi-
cle might depart from its lane and that the 
possibility of a collision with an overtaking 
vehicle in the adjacent lane is high, the 
steering assist function will operate even if 
the turn signals are operating.

*

: Boundary between asphalt and the side 

of the road, such as grass, soil, or a curb

■

Vehicle sway warning function

When the vehicle is swaying within a 
lane, the warning buzzer will sound and 
a message will be displayed on the 
multi-information display to alert the 
driver.

■

Lane centering function

This function is linked with dynamic 
radar cruise control with full-speed 
range and provides the required assis-
tance by operating the steering wheel 
to keep the vehicle in its current lane.

When dynamic radar cruise control with 
full-speed range is not operating, the lane 
centering function does not operate.
In situations where the white (yellow) lane 
lines are difficult to see or are not visible, 
such as when in a traffic jam, this function 
will operate to help follow a preceding 
vehicle by monitoring the position of the 
preceding vehicle.
