can be performed only by operating
the accelerator pedal, and the fre-
quency of switching to the brake
pedal can be greatly reduced.
Since the deceleration when the
accelerator pedal is released is
stronger than that of a conventional
vehicle, the vehicle can be deceler-
ated smoothly by slowly releasing
the pedal the accelerator pedal

■When Regeneration Boost cannot be used In the following cases, the system does not operate.
●When “X-MODE” is activated (If equipped)
●When the brake system or EV system is malfunctioning
●When regenerative braking is limited
regenerative braking may be restricted
in the following situations:
• When the amount of charge of the
traction battery is high • When the temperature of the traction battery is low or extremely high
• When the temperature of the electric motor or power control unit is extremely high
• When regenerative braking is continu- ally used for a long time
■Regenerative Braking
●The vehicle cannot be stopped by just releasing the accelerator pedal. Step on the brake pedal when the vehicle is
stopped.
●If the power switch is turned off and
then the EV system is restarted, the Regeneration Boost will be turned off.
●When driving at high speeds, the feel-ing of deceleration due to regenera-
tive braking is smaller than in a normal car.
●The maximum deceleration varies depending on the vehicle speed.
●Regeneration Boost cannot be used when the following message is dis-played on the multi-information dis-
play. When decelerating, firmly step on the brake to decelerate.
• “Regeneration Boost Unavailable XMODE Activated”• “Regeneration Boost Temporarily
Unavailable Press Brake to Deceler- ate”
• “Regeneration Boost Temporarily

The brake hold standby indicator
(green) comes on. While the system
is holding the brake, the brake hold
operated indicator (yellow) comes
on.
■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.
●“Parking Brake Unavailable” or “Park-
ing Brake Malfunction Visit Your
Dealer” is displayed on the multi-infor-
mation display.
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.
●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 on the multi-information display, read the message and follow the instruc-
tions.
●To turn the system off while the sys-
tem is holding the brake, firmly depress the brake pedal and press the button again.
■When the parking brake is set auto-
matically while the system is hold- ing the brakes

Driving
Constant speed cruising:
When there are no vehicles ahead
The vehicle drives at the speed set by the driver.
If the set vehicle speed is exceeded while driving down a hill, the set vehicle speed
display will blink and a buzzer will sound.
Deceleration and follow-up cruising
When a preceding vehicle driving slower than the set vehicle sp eed is
detected
When a vehicle is detected driving ahead of your vehicle, the v ehicle automatically
decelerates and if a greater reduction in vehicle speed is nece ssary, the brakes are
applied (the stop lights will come on at this time). The vehicl e is controlled to main-
tain the vehicle-to-vehicle distance set by the driver, in acco rdance with changes in
the speed of the preceding vehicle. If vehicle deceleration is not sufficient and the
vehicle approaches the vehicle ahead, the approach warning will sound.
Acceleration
When there are no longer any preceding vehicles driving slower than the
set vehicle speed
The vehicle accelerates until the set vehicle speed is reached and then resumes
constant speed cruising.
Starting off: If a preceding vehicle stops, the vehicle will al so stop (con-
trolled stop). After the preceding vehicle starts off, pressing the “RES”
switch or depressing the accelerator pedal will resume follow-u p cruising
(start off operation). If a start off operation is not performe d, the con-

5-4. Using the driving support systems
The actual vehicle-to-vehicle distance
varies in accordance with the vehicle
speed. Also, when the vehicle is
stopped by system control, it will be
stopped at a certain distance from the
preceding vehicle, depending on the
situation, regardless of the setting.
■Operating conditions
●D shift position is selected.
●The desired set speed can be set when the vehicle speed is approxi-
mately 30 km/h (20 mph) or more. (If the vehicle speed is set while driving at below approximately 30 km/h [20
mph], the set speed will be set to approximately 30 km/h [20 mph].)
■Accelerating after setting the vehi-cle speed
As with normal driving, acceleration can
be performed by depressing the acceler-
ator pedal. After accelerating, the vehi- cle will return to the set vehicle speed. However, while in vehicle-to-vehicle dis-
tance control mode, the vehicle speed may decrease to below the set vehicle speed in order to maintain the distance
from the preceding vehicle.
■When the vehicle is stopped by system control during follow-up cruising
●When the “RES” switch is pressed while the vehicle is stopped by system
control, if the preceding vehicle starts off within approximately 3 seconds, follow-up cruising will resume.
●If the preceding vehicle starts off within approximately 3 seconds of the
vehicle being stopped by system con- trol, follow-up cruising will resume.
■Automatic cancelation of vehicle-to-vehicle distance control mode
In the following situations, vehicle-to- vehicle distance control mode will be canceled automatically:
●When the brake control or output restriction control of a driving support
system operates (For example: Pre- Collision System, drive-start control)
●When the parking brake has been operated
●When the vehicle is stopped by sys-tem control on a steep incline
●When any of the following are detected while the vehicle is stopped by system control:
• The driver’s seat belt is unfastened • The driver’s door is opened• Approximately 3 minutes have
elapsed since the vehicle was stopped
The parking brake may be actived auto-
matically.
The shift position may automatically change to P. ( P.250)

■LTA control when operation is can- celed
When emergency driving stop system
operation is canceled, LTA control may also be canceled.
If driving operations are not
detected after the hands off steer-
ing wheel warning operates, a
buzzer will sound intermittently and
a message will be displayed to
warn the driver, and the system will
judge if the driver is responsive or
not. If driving operations, such as
holding the steering wheel, are not
performed within a certain amount
of time, the system will enter warn-
ing phase 2.
Vehicles with a driver monitor cam-
era: Depending on the type of
detection of the driver’s unrespon-
siveness, the system may skip
warning phase 1 and start the con-
trol of warning phase 2.
After entering warning phase 2, a
buzzer will sound in short intervals
and a message will be displayed to
warn the driver, and the vehicle will
slowly decelerate. If driving opera-
tions, such as holding the steering
wheel, are not performed within a
certain amount of time, the system
will determine that the driver is not
responsive and enter the decelera-
tion stop phase.
The audio system will be muted until
the driver becomes responsive.
When the vehicle is decelerating, the
brake lights may illuminate, depending
on the road conditions, etc.
After the vehicle has decelerated a cer-
tain amount, the emergency flashers
(hazard lights) will flash.
After the driver is judged as being
not responsive, a buzzer will sound
continuously and a message will be
displayed to warn the driver, and
the vehicle will slowly decelerate
and stop. While the vehicle is
decelerating, the emergency flash-
ers (hazard lights) will flash to warn
other drivers of the emergency.
After the vehicle is stopped, the
parking brake will be applied auto-
matically. After entering the stop
and hold phase, the buzzer will
continue sounding continuously, the
emergency flashers (hazard lights)
will flash to warn other drivers of
the emergency, and the doors will
unlock.

Calculated vehicle route
When the vehicle is moving, the side sensors or side cameras ca n detect
objects. While the vehicle is moving, if a detected object can no longer be
detected by the side sensors or side cameras, the location of t he object rel-
ative to the vehicle is estimated. If the object is determined to be in the esti-
mated path of the vehicle, the object warning function will ope rate.
Object detected by side sensors or side cameras
1 The vehicle is stopped and objects along the sides of the vehicle are not
detected.
2 Objects are detected as the vehicle is moving.
3 Even though the objects are outside of the detection area of the side
sensors or side cameras, a warning is displayed and a buzzer so unds.
■Object warning function operating conditions
●The Advanced Park is operating.
●The vehicle moves about 7 m (23.0 ft.)
after the EV system is started.
●The R shift position is selected.
●After the D shift position has been selected, the vehicle has moved 7 m
