LKA (Lane-Keeping Assist) (If Equipped)
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-information 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 cen-
ter of the lane.
Lane keeping assist function
This function will be active when the vehicle-to-vehicle distance control mode of the
cruise control 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 func-
tion is active, a slight steering torque will be applied, to help the driver maintain the vehi-
cle inside the lane.
■Tu r n i n g t h e L K A s y s t e m o n
The lane departure warning function and lane keeping assist function will be activated
depending on the recognition condition of lane markers, vehicle speed and the setting of
radar cruise control (vehicle-to-vehicle distance control mode).

tem.
“LKA” indicator will come on.
Press the switch again to turn the LKA
system off.

a buzzer when parallel parking or maneuvering into a garage. Always check the sur-
rounding area when using this system.
For details, refer to the “Navigation System Owner’s Manual”.
The wide view front monitor uses a super-wide angle lens to display on screen the areas
to the left and right of the vehicle and the blind spots to the front of the vehicle. This sys-
tem helps the driver check for approaching cars, bicycles and pedestrians when at inter-
sections with poor visibility.

Turn the headlight switch to the “AUTO”
position.
Push the lever away from you.
The Automatic High Beam indicator will
come on when the headlights are turned
on automatically to indicate that the sys-
tem is active.

The Automatic High Beam uses an in-vehicle camera sensor to assess the brightness of
streetlights, the lights of oncoming and preceding vehicles, etc., and automatically turns
high beam on or off as necessary.
When all of the following conditions are fulfilled, high beam will be automatically turned on
(after approximately 1 second):
• Vehicle speed is above approximately 20 mph (32 km/h).
• The area ahead of the vehicle is dark.
• There are no oncoming or preceding vehicles with headlights or tail lights turned on.
