■“X-MODE”
 P. 3 8 2
Acceleration/deceleration con-
trol can be performed only by
operating the accelerator pedal,
and the frequency of switching
to the brake pedal can be
greatly reduced. Since the
deceleration when the accelera-
tor pedal is released is stronger
than that of a conventional vehi-
cle, the vehicle can be deceler-
ated smoothly by slowly
releasing the pedal the acceler-
ator pedal without completely releasing it.
When the Regeneration Boost
switch is pressed, the regenera-
tive braking force, when the
accelerator pedal is released,
becomes stronger than usual.
■When Regeneration Boost can-
not 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 lim-
ited
Regenerative braking may be
restricted in the fo llowing situations:
• When the amount of charge of the traction battery is high
• When the temperature of the trac-
tion battery is low or extremely
high
• When the temperature of the elec-
tric motor or powe r control unit is
extremely high
• When regenerative braking is con- tinually used for a long time

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 blin k and a buzzer will sound.
Deceleration and follow-up cruising
When a preceding vehicle driving slower than the set vehicle
speed is detected
When a vehicle is detected driving ahead of your vehicle, the v ehicle auto-
matically decelerates and if a greater reduction in vehicle spe ed is neces-
sary, the brakes are applied (the stop lights will come on at t his time). The
vehicle is controlled to maintai n the vehicle-to-vehicle distance set by the
driver, in accordance with changes in the speed of the precedin g vehicle. If
vehicle deceleration is not sufficient and the vehicle approaches the vehicle
ahead, the approach wa rning will sound.
Acceleration
When there are no longer any preceding vehicles driving slower
than the set vehicle speed
The vehicle accelerates until th e set vehicle speed is reached and then
resumes constant speed cruising.
Starting off: If a preceding vehi cle stops, the vehicle will also stop
(controlled stop). After the preceding vehicle starts off, pressing
the “RES” switch or depressing the accelerator pedal will resum e
follow-up cruising (start off operation). If a start off operat ion is not
performed, the controlled stop will continue.

Each time the switch is pressed,
the vehicle-to-vehicle distance
setting will change as follows:
If a preceding vehicle is detected,
the preceding vehicle mark will
be displayed.
The actual vehicle-to-vehicle dis-
tance varies in accordance with the
vehicle speed. Also, when the vehi-
cle is stopped by system control, it
will be stopped at a certain distance
from the preceding vehicle,
depending on the situation, regard-
less of the setting.
■Operating conditions
●D shift position is selected.
●The desired set speed can be set
when the vehicle speed is approx-
imately 20 mph (30 km/h) or more.
(If the vehicle speed is set while
driving at below approximately 20
mph [30 km/h], th e set speed will
be set to approxi mately 20 mph
[30 km/h].)
■Accelerating after setting the
vehicle speed
As with normal driving, acceleration
can be performed by depressing the
accelerator pedal. After accelerat-
ing, the vehicle will return to the set
vehicle speed. However, while in
vehicle-to-vehicle distance control
mode, the vehicle speed may
decrease to below the set vehicle
speed in order to maintain the dis-
tance 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 approxi-
mately 3 seconds, follow-up cruis-
ing will resume.
●If the preceding vehicle starts off
