■Brake hold system operating con- ditions
The brake hold system cannot be turned on in the following conditions:
●The driver’s door is not closed.
●The driver is not wearing the seat belt.
●The parking brake is engaged.
If any of the conditions above are
detected when the brake hold system is enabled, the system will turn off and the brake hold standby indicator light will go
off. In addition, if any of the conditions are detected while the system is holding the brake, a warning buzzer will sound
and a message will be shown on the multi-information display. The parking brake will then be set automatically.
■Brake hold function
●If the brake pedal is left released for a period of about 3 minutes after the
system has started holding the brake, the parking brake will be set automati-cally. In this case, a warning buzzer
sounds and a message is shown on the multi-information display.
●To turn the system off while the sys-tem is holding the brake, firmly
depress the brake pedal and press the button again.
●The brake hold function may not hold the vehicle when the vehicle is on a steep incline. In this situation, it may
be necessary for the driver to apply the brakes. A warning buzzer will sound and the multi-information dis-
play will inform the driver of this situa- tion. If a warning message is shown

WARNING
■When the vehicle is on a steep
incline
Take care when using the brake hold system on a steep incline, exercise
caution. The brake hold function may not hold brakes in such situations.Also, the system may not activate
depending on the angle of the slope.
■When stopped on a slippery road
The system cannot stop the vehicle when the gripping ability of the tires has been exceeded. Do not use the
system when stopped on a slippery road.
NOTICE
■When parking the vehicle
The brake hold system is not designed for use when parking the
vehicle for a long period of time. Turn- ing the engine switch off while the
system is holding the brake may release the brake, which would cause the vehicle to move. When operating

PCS (Pre-Collision System)*
The pre-collision system uses a rad ar sensor and front camera to
detect objects ( P.217) in front of the vehicle. When the system
determines that the possibility of a frontal collision with an object is
high, a warning operates to urge the driver to take evasive act ion
and the potential brake pressure is increased to help the drive r
avoid the collision. If the syste m determines that the possibility of a
frontal collision with an object is extremely high, the brakes are
automatically applied to help avoid the collision or help reduc e the
impact of the collision.
The pre-collision system can be disabled/enabled and the warnin g timing
can be changed. ( P.221)

■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.
“BRAKE!”
■Pre-collision brake assist
When the system determines that
the possibility of a frontal collision is
high, the system applies greater
braking force in relation to how
strongly the brake pedal is
depressed.
■Pre-collision braking
If the system determines that the
possibility of a frontal collision is
extremely high, the brakes are
automatically applied to help avoid
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 with a
pedestrian is high and that there is
sufficient space for the vehicle to be
steered into within its lane, and the
driver has begun evasive maneuver
or steering, emergency steering
assist will assist the steering move-
ments to help enhance the vehicle
stability and for lane departure pre-
vention. During operation, the indi-
cator will illuminate in green.
■Intersection right/left turn
assistance (for region A)
If the system determines that there
is a high possibility of a collision in
the following situations, it will assist
with Pre-collision warning and, if
necessary Pre-collision braking.
Depending on the configuration of
the intersection, it may not be pos-
sible to support.

This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, d etermines the current vehicle-to-vehicle fol-
lowing distance, and operates to maintain a suitable following distance from
the vehicle ahead. The desired vehicle-to-vehicle distance can also be set
by operating the vehicle-to-vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distanc e may become
shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appe ars
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-
tem applies the brakes (the stop lights will come on at this ti me). The system will
respond to changes in the speed of the vehicle ahead in order t o maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning war ns you when the sys-
tem cannot decelerate sufficiently 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, pressin g the “+RES” switch or
depressing the accelerator pedal (start-off operation) will res ume follow-up cruising.
If the start-off operation is not performed, system control con tinues to keep your
vehicle stopped.

When the turn signal lever is operated and your vehicle moves t o an overtaking lane
while driving at 80 km/h (50 mph) or more, the vehicle will acc elerate to help to over-
take a passing vehicle.
The system’s identification of what is an overtaking lane may b e determined solely
based on the location of the steering wheel in the vehicle (lef t side driver position
versus right side driver position.) If the vehicle is driven to a region where the over-
taking lane is on a different side from where the vehicle is no rmally driven, the vehi-
cle may accelerate when the turn signal lever is operated in th e opposite direction to
the overtaking lane (e.g., if the driver normally operates the vehicle in a region
where the overtaking lane is to the right but then drives to a region where the over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).
Example of acceleration

●The following situations may occur
during use. • Depending on the shape of the object and other factors, the detection dis-
tance may shorten, or detection may be impossible.• Detection may be impossible if static
objects draw too close to the sensor. • There will be a short delay between static object detection and display
(warning buzzer sounds). Even at low speeds, there is a possibility that the object will come within 30 cm (1.0 ft.)
before the display is shown and the warning buzzer sounds.• It might be difficult to hear the buzzer
due to the volume of the audio system or air flow noise of the air conditioning system.
• It may be difficult to hear the sound of this system due to the buzzers of other systems.
■Objects which the system may not
be properly detected
The shape of the object may prevent the sensor from detecting it. Pay particular
attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro-
jecting outwards in the direction of your vehicle
■Situations in which the system may not operate properly
Certain vehicle conditions and the sur- rounding environment may affect the ability of a sensor to correctly detect
objects. Particular instances where this may occur are listed below.
●There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors will resolve this problem.)
●A sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor
is frozen the sensor display may be
displayed abnormally, or objects, such as a wall, may not be detected.
●When a sensor or the area around a sensor is extremely hot or cold.
●On an extremely bumpy road, on an incline, on gravel, or on grass.
●When vehicle horns, vehicle detec-tors, 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.
●Pedestrians that are hard to reflect ultrasonic waves (ex. skirts with gath-ers or frills).
●When objects that are not perpendicu-lar to the ground, not perpendicular to
the vehicle traveling direction, uneven, or waving are in the detection 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, motor-cycle, 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
