Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS)
The Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS)
alerts the driver that the vehicle may be deviating from its lane and it provides
steering assistance to help the driver stay within the vehicle lanes.
For details, refer to Section 4, “i-ACTIVSENSE”.
The steering wheel operation of the Lane-keep Assist System (LAS) & Lane
Departure Warning System (LDWS) has “Late” and “Early” steering assist timing
settings.
Do not rely completely on the Lane-keep Assist System (LAS) & Lane
Departure Warning System (LDWS):
Other details are described in the related text.
WARNING
• The Lane-keep Assist System (LAS) & Lane Departure Warning System
(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 Lane-keep Assist System (LAS) & Lane
Departure Warning System (LDWS) is limited. Always stay on course
using the steering wheel and drive with care.
NOTE
The Lane-keep Assist System (LAS) & Lane Departure Warning System
(LDWS) may not be able to detect white (yellow) lane lines correctly and it
may not operate normally.
Other details are described in the related text.
“Late” and “Early” timing can be changed (timing at which steering operation
assist is pro
vided) by changing the setting. Details are described in Setting
Change (Personalisation Features) in the related text.

Advanced Smart City Brake Support (Advanced SCBS) (Except The
Philippines, Taiwan)
The Smart City Brake Support [Reverse] (SCBS R) is a system which is designed to reduce
damage in the event of a collision by operating the brake control (SCBS brake) when the
system’s ultrasonic sensors detect an obstruction at the rear of the vehicle while driving at a
speed of about 2 to 8 km/h (2 to 4 mph) and the system determines that a collision is
unavoidable. In addition, when the driver depresses the brake pedal while the system is in
the operation range at a vehicle speed of about 2 to 8 km/h (2 to 4 mph), the brakes are
applied firmly and quickly to provide assistance. (Brake Assist (SCBS brake assist))
Smart City Brake Support [Reverse] (SCBS R)
The Advanced Smart City Brake Support (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 ahead or pedestrian and determines that a collision with the object is unavoidable while
the vehicle is driven at a vehicle speed of about 4 to 80 km/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.
Smart City Brake Support [Forward] (SCBS F) (The Philippines, Taiwan)
The Smart City Brake Support [Forward] (SCBS F) system alerts the driver of a possible
collision using an indication in the display and a warning sound when the Forward
Sensing Camera (FSC) detects 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 brake control (SCBS brake) when the system determines that a
collision 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 speed
between your vehicle and the vehicle in front of you is less than about 20 km/h (12 mph).
• The 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.
• (Advanced Smart City Brake Support (Advanced SCBS)) Do not rely completely on the system:
WARNING
The Advanced Smart City Brake Support (Advanced SCBS) system operates
in response to a vehicle ahead or a pedestrian. The system does not operate
in response to obstructions such as a wall, 2-wheeled vehicles, or animals.
• (Smart City Brake Support [Forward] (SCBS F))
The Advanced Smart City Brake Support (Advanced SCBS) is a system
which operates in response to a vehicle ahead. The system may not be able
to detect or react to 2-wheeled vehicles or pedestrians.

Smart Brake Support (SBS)
The Smart Brake Support (SBS) system alerts the driver of a possible collision
using a display and warning sound if the radar sensor (front) and the Forward
Sensing Camera (FSC) determine that there is the possibility of a collision with a
vehicle ahead while the vehicle is being driven at about 15 km/h or faster (10
mph or faster). Furthermore, if the radar sensor (front) and the Forward Sensing
Camera (FSC) determines that a collision is unavoidable, the automatic brake
control is performed to reduce damage in the event of a collision.
Do not rely completely on the Smart Brake Support (SBS) system and always
drive carefully:
The Smart Brake Support (SBS) is designed to reduce damage in the event of a
collision, not avoid an accident. The ability to detect an obstruction is limited
depending on the obstruction, weather conditions, or traffic conditions. Therefore, if
the accelerator pedal or brake pedal is mistakenly operated it could result in an
accident. Always verify the safety of the surrounding area and depress the brake pedal
or accelerator pedal while keeping a safer distance from vehicles ahead or on-coming
vehicles.
WARNING
In addition, when the driver depresses the brake pedal, the brakes are applied
firmly and quickly to assist. (Brake Assist (SBS brake assist)).

When Driving
For details, refer to Section 4, “i-ACTIVSENSE”.
If there is the possibility of a collision with a
vehicle ahead, the beep sounds continuously and a
warning is indicated in the active driving display.
Collision Warning
The Smart Brake Support (SBS) system may not operate under the following
conditions:
•If the vehicle is accelerated rapidly and it comes close to a vehicle ahead.
Although the objects which activate the system are four-wheeled vehicles, the
radar sensor (front) could detect the following objects, determine them to be an
obstruction, and operate the Smart Brake Support (SBS) system.
•Objects on the road at the entrance to a curve (including guardrails and
snow banks).
•The vehicle is driven at the same speed as the vehicle ahead.
•The accelerator pedal is depressed.
•A vehicle appears in the opposite lane while cornering or rounding a curve.
•When crossing a narrow bridge.
•When entering an underground parking area.
•Metal objects, bumps, or protruding objects on the road. NOTE
Smart Brake Support (SBS)
•The brake pedal is depressed.
•The steering wheel is being operated.
•The selector lever is being operated.
• The direction indicator is being used.
• When the vehicle ahead is not equipped with tail lights or the tail lights are
turned off.
• When warnings and messages, such as a dirty windscreen, related to the
Forward Sensing Camera (FSC) are being displayed in the multi-
information display.
•
When passing under a low gate or through a tunnel or narrow gate.
•If you suddenly come close to a vehicle ahead.
•When driving in areas where there is high grass or forage.
•Two-wheeled vehicles such as motorbikes or bicycles.
•Pedestrians or non-metallic objects such as standing trees.

i-ELOOP System
i-ELOOP is a regenerative braking system. When you depress the brake pedal or use
engine braking, the kinetic energy that occurs is converted to electrical energy by the
power generator and the converted electrical energy is stored in the rechargeable
battery (capacitor and battery). The stored electricity is used as power to charge the
battery and the vehicle's electrical devices.
For details, refer to Section 4, “i-ELOOP”.
• A variable voltage alternator is incorporated in the power generator which
converts the kinetic energy to electricity and can generate electricity efficiently
according to the vehicle conditions.
• A capacitor is used to store large amounts of electricity instantly which can be
utilized quickly.
• A DC-DC converter is incorporated which steps down the stored electricity to
voltage useable by the vehicle's electrical devices.
