distance control mode, the vehicle automatically accelerates or
decelerates in order to maintain a set following distance from vehi-
cles ahead.

LKA (Lane-Keeping Assist)
: If equipped
While driving on a freeway or motor highway that has lane markings,
this system recognizes the lanes using a camera as a sensor to
assist the driver with staying in the lane. The LKA system has two
functions.
■ Lane departure warning function
If the system judges that the vehicle may deviate from its lane, it
alerts the driver using rapid be eping, indications on the multi-
information display, and a sensory warning
* given via the steer-
ing wheel.
*: A slight steering torque is applied for a short period of time in
the direction of the center of the lane.
■ Lane keeping assist function
This function will be active when the vehicle-to-vehicle distance
control mode of the cruise control ( P. 270) is set with vehicle
speed above approx. 50 mph (approx. 75 km/h) and while the
lane departure warning function is active. When the lane keep-
ing assist function is active , a slight steering torque will be
applied, to help the driver mainta in the vehicle inside the lane.

■No-handed driving warning
If the steering wheel is not operated for about 15 seconds on a straight road
or about 5 seconds on a curve, the buzzer will beep twice, indicators on the
multi-information display will flash, and the lane keeping assist function will
be temporarily canceled. If you drive the vehicle with your hands lightly
touching the steering wheel, this may also be detected as no-handed driv-
ing.
■ When the vehicle has been parked in the sun
The LKA system functions may not be available for a while after driving has
started. In such cases, turn the LKA system off and turn it on again after nor-
mal temperature returns. When the temperature in the cabin decreases and
the temperature around the camera sensor becomes suitable for its opera-
tion, the functions will begin to operate.
■ Warning lights and warning messages for LKA
Warning lights and messages are used to indicate a system malfunction or
to inform the driver of the need for caution while driving. ( P. 496, 510)
CAUTION
■Before using the LKA system
Do not rely on the LKA system to remain within a selected lane. The LKA
system is not designed to enable inattentive driving. The steering wheel
should be operated by the driver to mainta in the vehicle in a suitable position
within its lane. Always drive carefully.
