Lane-keep Assist System (LAS) & Lane DepartureWarning System (LDWS)
*
The LAS & LDWS alerts the driver that the vehicle may be deviat ing from its lane and it
provides steering assistance to help the driver stay within the vehicle lanes.
The Forward Sensing Camera (FSC) detects the white lines (yello w lines) of the vehicle
lane in which the vehicle is traveling and if the system determ ines that the vehicle may
deviate from its lane, it operates the electric power steering to assist the driver's steering
operation. The system also alerts the driver by activating a la ne departure warning sound,
vibrating the steering wheel, and indicating an alert in the di splay. Use the system when you
drive the vehicle on ro ads with white (yellow) lines such as ex pressways and highways.
Refer to Forward Sensing Camera (FSC) on page 4-192.

Do not rely completely on the LAS & LDWS:
 The LAS & LDWS is not an automatic driving system. In addition, the system is not designed
to compensate for a driver's lack of caution, and over-reliance on the system could lead to
an accident.
 The detection ability of the LAS & LDWS is limi ted. Always stay on course using the steering
wheel and drive with care.
Do not use the LAS & LDWS in the following cases:
The system may not operate adequately accordin g to the actual driving conditions, resulting
in an accident.

NOTE
The LAS & LDWS indication is gray when
the system detects only a white (yellow)
line on either the left or right, and the
indication changes to white when the
system detects white (yellow) lines on both
the left and right sides.

The LAS & LDWS goes on stand-by
status in the following cases:
The system cannot detect white (yellow)
lane lines.
The vehicle speed is less than about 60
km/h (37 mph).
The ABS/TCS is operating.
The TCS is turned off.
(If the TCS is turned off while the
system is operational, a warning beep is
heard and the system goes on standby.)
The vehicle is making a sharp curve.
The brake pedal is depressed.
The steering wheel is operated abruptly.
The width of a lane is excessively
narrow or wide.
NOTE
The LAS & LDWS does not operate until
the system detects white (yellow) lane
lines on either the left or right.
When the system detects a white
(yellow) lane line on one side only, the
system will not operate the steering
wheel operation assist and the warning
for the lane line on the side that is not
being detected. The steering wheel
operation assist and the warning is only
for a lane deviation on the side that is
being detected.
If the driver takes his or her hands off
the steering wheel (not holding the
steering wheel), the warning sound is
activated and an alert is indicated in the
multi-information display or the active
driving display.

Active Driving Display Multi-information Display
If the steering wheel is held lightly, or
depending on the road conditions, the
system may detect that you have
released the steering wheel (not holding
the steering wheel) even if you are
holding it, and display a message in the
multi-information di splay or the active
driving display.

▼Lane Departure Warning
If the system determines that the vehicle may deviate from its
lane, the lane departure
warning (beep sound, rumble sound
*1, or steering wheel vibration) is activated and the
direction in which the system determines that the vehicle may d eviate is indicated in the
multi-information display an d the active driving display.
If the system determines that the vehicle may deviate from its lane, the color of the lane line
on the side being detected by the system changes from white to amber, and flashes.

NOTE
If you have set the lane departure warning sound to the beep sound/rumble sound*1
setting, the warning sound may not be heard depending on the surrounding noise
conditions.
If you have set the lane departure warning system to the steering wheel vibrations setting,
the vibration may not be felt dependi ng on the road surface conditions.
When the setting for the steering operation assist is changed to operational, the warnings
can be set to activate/not activate. (When the setting for the steering operation assist is
changed to non-operational, the warnings cannot be set to not activate.)
Refer to Setting Change (Personalization Features) on page 9-10.
The LAS & LDWS can be changed to the following settings regardless of whether the
steering operation assist has been set to operational/non-operational. Always check the
setting status when driving the vehicle and make setting changes if necessary.

Advanced Smart City Brake Support (Advanced SCBS)*
The Advanced SCBS alerts the driver of a possible collision using the display and a warning
sound when the Forward Sensing Camera (FSC) detects a vehicle a head or pedestrian and
determines that a collision with the object is unavoidable whil e the vehicle is driven at a
vehicle speed of about 4 to 80 k m/h (2 to 50 mph) if the object is a vehicle ahead and about
10 to 80 km/h (6.2 to 50 mph) if the object is a pedestrian. In addition, the system reduces
damage in the event of a collision by operating the brake contr ol (Advanced SCBS brake)
when the system determines that a collision is unavoidable. In addition, when the driver
depresses the brake pedal, the brakes are applied firmly and qu ickly to assist. (Brake Assist

Do not rely completely on the Advanced SCBS system:
 The Advanced SCBS system is only designed to reduce damage in the event of a collision.
Over reliance on the system leading to the accelerator pedal or brake pedal being
mistakenly operated could result in an accident.
 The Advanced SCBS system operates in respo nse to a vehicle ahead or a pedestrian. The
system does not operate in response to obstru ctions such as a wall, 2-wheeled vehicles, or
animals.

▼Collision Warning
If there is the possibil
ity of a collision with
a vehicle ahead, the beep sounds
continuously and a warning is indicated in
the multi-information d isplay or the active
driving display.
NOTE
The operation distance and volume of the
collision warning can be changed. Refer
to Personalization Features on page
9-10.
▼ Automatic Brake Operation Display
The automatic brake operation display is
indicated on the multi-information display
after the Advanced SCBS is operated.
NOTE
The collision warning beep sounds
intermittently while the Advanced SCBS
brake or brake assist (Advanced SCBS

If the vehicle is stopped by the Advanced
SCBS operation and the brake pedal is
not depressed, the warning beep sounds
1 time after about 2 seconds and the
Advanced SCBS brake is automatically
released.

Smart City Brake Support (SCBS)*
The SCBS system alerts the driver of a possible collision using an indication in the display
and a warning sound when the Forward Sensing Camera (FSC) detec ts a vehicle ahead and
determines that a collision with a vehicle ahead is unavoidable while the vehicle is being
driven at a vehicle speed of about 4 to 80 km/h (2 to 50 mph). In addition, the system
reduces damage in the event of a collision by operating the bra ke control (Smart City Brake
Support (SCBS) brake) when the system determines that a collisi on is unavoidable while the
vehicle is being driven at a vehicle speed of about 4 to 30 km/ h (2 to 18 mph). It may also
be possible to avoid a collision if the relative s peed between your vehicle and the vehicle in
front of you is less than about 20 km/h (12 mph). In addition, when the driver depresses the
brake pedal while the system is in the operation range at about 4 to 30 km/h (2 to 18 mph),
the brakes are applied firmly and quickly to assist. (Brake Ass ist (Smart City Brake Support
(SCBS) brake assist))

Do not rely completely on the SCBS system:
 The SCBS system is only designed to reduce da mage in the event of a collision. Over reliance
