■Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
■Pre-collision brake assist
When the system determines that the possibility of a frontal co lli-
sion is high, the system applies greater braking force in relat ion to
how strongly the brake pedal is depressed.
■Pre-collision braking
If the system determines that the possibility of a frontal coll ision is
extremely high, the brakes are automatically applied to help av oid
the collision or reduce the impact of the collision.
■Emergency steering assist (for region A)
If the system determines that the possibility of a collision wi th a
pedestrian is high and that there is sufficient space for the v ehicle
to be steered into within its lane, and the driver has begun ev asive
maneuver or steering, emergency steering assist will assist the
steering movements to help enhance the vehicle stability and fo r
lane departure prevention.

● For region A: In addition to the above, in some situations, such as the fol-
lowing, the emergency steering assist may not operate.
• For region A: When the white (yellow) lane lines are difficult to see, such
as when they are faint, diverging/merging, or a shadow is cast upon them
• For region A: When the lane is wider or narrower than normal
• For region A: When there is a light and dark pattern on the ro ad surface,
such as due to road repairs
• For region A: When a pedestrian is detected near the centerlin e of the
vehicle
• For region A: When the target is too close
• For region A: When there is insufficient safe or unobstructed space for
the vehicle to be steered into
• For region A: If oncoming vehicle is present
• For region A: If VSC function is operating
● In some situations such as the following, sufficient braking force or steering
force (for region A) may not be obtained, preventing the system from per-
forming properly:
• If the braking functions cannot operate to their full extent, such as when
the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other sli ppery sur-
face
• When the road surface has deep wheel tracks
• When driving on a hill road
• When driving on a road that has inclines to the left or right
■ If VSC is disabled
● If VSC is disabled (P. 533), the pre-collision brake assist and pre-collision
braking functions are also disabled.
● The PCS warning light will turn on and “VSC Turned Off. Pre-Collision Brake
System Unavailable.” will be displayed on the multi-information display.

Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system aut omatically
decelerates your vehicle. When a greater reduction in vehicle s peed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate su ffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also sto p (vehicle is
stopped by system control). After the vehicle ahead starts off, pushing the
cruise control lever up or depressing the accelerator pedal (st art-off opera-
tion) will resume follow-up crui sing. If the start-off operation is not per-
formed, system control continues to keep your vehicle stopped.
When the turn signal lever is operated and your vehicle moves t o an over-
taking lane while driving at 80 km/h (50 mph) or more, the vehi cle will
accelerate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may b e deter-
mined solely based on the location of the steering wheel in the vehicle (left
side driver position versus right side driver position.) If the vehicle is driven
to a region where the overtaking lane is on a different side fr om where the
vehicle is normally driven, the vehicle may accelerate when the turn signal
lever is operated in the opposite direction to the overtaking l ane (e.g., if the
driver normally operates the vehi cle in a region where the overtaking lane
is to the right but then drives to a region where the overtakin g lane is to the
left, the vehicle may accelerate when the right turn signal is activated).
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The syst em then
returns to constant speed cruising.

● On an extremely bumpy road, on an incline, on gravel, or on grass.
● When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle
● A sensor is coated with a sheet of spray or heavy rain.
● If objects draw too close to the sensor.
● When a pedestrian is wearing clothing that does not reflect ultrasonic waves
(ex. skirts with gathers or frills).
● When objects that are not perpendicular to the ground, not perpendicular to
the vehicle traveling direction, uneven, or waving are in the d etection range.
● Strong wind is blowing
● When driving in inclement weather such as fog, snow or a sandstorm
● When an object that cannot be detected is between the vehicle and a
detected object
● If an object such as a vehicle, motorcycle, bicycle or pedestrian cuts in front
of the vehicle or runs out from the side of the vehicle
● If the orientation of a sensor has been changed due to a collision or other
impact
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicy cle carrier, or
snow plow
● If the front of the vehicle is raised or lowered due to the carried load
● If the vehicle cannot be driven in a stable manner, such as when the vehicle
has been in an accident or is malfunctioning
● When a tire chains, compact spare tire or an emergency tire puncture repair
kit is used
● When a sensor or the area around a
sensor is extremely hot or cold.

■ Situations in which the system may operate even if there is no possibil-
ity of a collision
In some situations, such as the following, the system may opera te even
though there is no possibility of a collision.
● When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad crossings, toll gates and parki ng lots)
● When there is a rut or hole in the surface of the road
● When driving on a metal cover (grating), such as those used for drainage
ditches
● When driving up or down a steep slope
● If a sensor is hit by a large amount of water, such as when driving on a
flooded road
● There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
● A sensor is coated with a sheet of spray or heavy rain
● When driving in inclement weather such as fog, snow or a sandstorm
● When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices which

PKSB (Parking Suppor t Brake)
■Parking Support Brake function (static objects)
Ultrasonic sensors are used to detect static objects, such as a wall,
in the detection area when driving at a low speed or backing up .
( P. 483)
■Parking Support Brake function (rear-crossing vehicles) (if
equipped)
Rear radar sensors are used to detect approaching vehicles in t he
detection area behind the vehicle when backing up. ( P. 4 8 7 )
: If equipped
The Parking Support Brake system consists of the following
functions that operate when driving at a low speed or backing
up, such as when parking. When the system determines that a
collision with a detected object is high, a warning operates to
urge the driver to take evasive action. If the system determine s
that the possibility of a collision with a detected object is
extremely high, the brakes are automatically applied to help
avoid the collision or help reduce the impact of the collision.

If the Parking Support Brake determines that a collision with a
detected object or pedestrian is possible, the hybrid system ou tput will
be restricted to restrain any increase in the vehicle speed. (H ybrid
system output restriction control: See figure 2.)
Additionally, if the accelerator pedal continues to be depresse d, the
brakes will be applied automatically to reduce the vehicle spee d.
(Brake control: See figure 3.)

S-IPA (Simple Intelligent Parking Assist
System)
The Simple Intelligent Parking Assist System automatically oper ates
the steering wheel to provide support when backing into an area near
a target parking spot, and when departing from a parallel parki ng spot.
(Shift lever operations and speed adjustment when moving forwar d or
backing up are not performed automatically.)
● The Simple Intelligent Parking Assist System does not park the
vehicle automatically. It is a system that provides support whe n
pulling out of a perpendicular or parallel parking spot.
● The Simple Intelligent Parking Assist System provides steering
wheel operation assistance to guide the vehicle toward the sele cted
intended parking spot. The selected intended parking spot may n ot
always be reachable, depending on road and vehicle conditions a t
the time of parking, and the distance to the intended parking s pot.
While the Simple Intelligent Parking Assist System is operating , if the
system detects an obstacle that could result in a collision, th e emer-
gency brakes operate, regardless of whether the PKSB (Parking S up-
port Brake) system is on or off. ( P. 495)
