LKA (Lane-Keeping Assist)∗∗
: If equipped
While driving on a freeway or motor highway that has lane markers, 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 beeping, indications on the multi-infor-
mation display, and a sensory warning
* given via the steering 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. 216) is set with vehicle
speed above approx. 45 mph (approx. 72 km/h) and while the lane
departure warning function is active. When the lane keeping assist
function is active, a slight steering torque will be applied, to help the
driver maintain the vehicle inside the lane.

HS250h_U_75050U
■Using the system in recirculated air mode
The windows will fog up more easily if recirculated air mode is used.
■Window defogger feature
Recirculated air mode may automatically switch to (outside air) mode in sit-
uations where the windows need to be defogged.
■When micro dust and pollen filter is active
●In order to prevent the windshield from fogging up when the outside air is cold,
the following may occur:
• Outside air mode does not switch to (recirculated air) mode.
• The air conditioning system operates automatically.
• The operation cancels after 1 minute.
●In rainy weather, the windows may fog up. Press .
■When outside air temperature is below 32°F (0 °C)
The air conditioning function may not operate even when
is pressed.
■Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to be
emitted from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditio ning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic mode.
CAUTION
■To prevent the windshield from fogging up
Do not use
during cool air operation in extremely humid weather. The dif-
ference between the temperature of the outside air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
