■Turning the LKA system on
Press the LKA switch to turn the LKA sys-
tem on.
The LKA indicator illuminates and a

driver when the vehicle might depart from its lane and provides assistance by operating
the steering wheel to keep the vehicle in its lane. Furthermore, the system also provides
steering assistance when dynamic radar cruise control with full-speed range is operating
to keep the vehicle in its lane.
The LKA system recognizes visible white or yellow lines with the camera sensor on the
upper portion of the front windshield.

■Resuming follow-up cruising when the vehicle has been stopped by system
control (vehicle-to-vehicle distance control mode)
After the vehicle ahead of you starts off,
push the lever up.
Your vehicle will also resume follow-up
cruising if the accelerator pedal is
depressed after the vehicle ahead of you
starts off.
■Canceling and resuming the speed control
Pulling the lever toward you cancels
the speed control.
The speed control is also canceled
when the brake pedal is depressed.
(When the vehicle has been stopped
by system control, depressing the
brake pedal does not cancel the set-
ting.)
Pushing the lever up resumes the
cruise control and returns vehicle
speed to the set speed.
However, when a vehicle ahead is not
detected, cruise control does not
resume when the vehicle speed is
approximately 25 mph (40 km/h) or
less.1
