Driving
high, the brakes are automatically
applied to help avoid the collision or
reduce the impact of the collision.
■Emergency steering assist
If the system determines that the
following conditions are met, assis-
tance will be provided to help
enhance vehicle stability and pre-
vent lane departure. During assis-
tance, in addition to the pre-
collision warning, the following icon
will be displayed on the multi-infor-
mation display.
 The possibility of a collision is
high
 There is sufficient space within
the lane to perform evasive
steering maneuvers
 The driver is operating the steer-
ing wheel
During assistance, the pre-collision
warning will operate and a mes-
sage will be displayed to warn the
driver.
■Intersection collision avoid-
ance support (left/right turn)
In situations such as the following,
if the system determines that the
possibility of a collision is high, the
pre-collision warning and pre-colli-
sion braking will operate. Depend-
ing on the intersection, assistance
may not operate correctly.
 When turning left/right at an
intersection and crossing the
path of an oncoming vehicle
 When turning left/right and an
oncoming pedestrian or bicycle
is detected
■Intersection collision avoid-
ance support (crossing vehi-
cles)
At an intersection, etc., if the sys-
tem determines that the possibility
of a collision with an approaching
vehicle or motorcycle is high, the
pre-collision warning and pre-colli-
sion braking will operate. Depend-
ing on the intersection, assistance
may not operate correctly.

■Acceleration Suppression at
Low Speed
When driving at a low speed, if the
accelerator pedal is strongly
depressed and the system deter-
mines that there is a possibility of a
collision, EV system output will be
restrained or the brakes will be
applied weakly to restrict accelera-
tion. During operation, a buzzer will
sound and a warning indicator and
message will be displayed on the
multi-information display.

WARNING
■Pre-collision braking
●When the pre-collision braking function is operating, a large amount of braking force will be
applied.
●Pre-collision braking function is not intended for remain stopped. If the vehicle is stopped by pre-collision
braking function, the driver should operate the brakes as necessary.
●The pre-collision braking function may not operate if certain opera-tions are performed by the driver. If
the accelerator pedal is being depressed strongly or the steering wheel is being turned, the system
may determine that the driver is tak- ing evasive action and possibly pre-vent the pre-collision braking
function from operating.
●If the brake pedal is being
depressed, the system may deter- mine that the driver is taking eva-sive action and possibly delay the
operation timing of the pre-collision brake control.
■Acceleration Suppression at Low Speed
If the steering wheel is being turned,
the system may determine that the driver is taking evasive action and possibly prevent the Acceleration
Suppression at Low Speed function from operating.
■Emergency steering assist
●The emergency steering assist will be canceled when the system
determines that lane departure pre- vention control has completed.
●Depending on operations per-formed by the driver, emergency steering assist may not operate or
operation may be canceled.
• If the accelerator pedal is
depressed strongly, the steering wheel is turned heavily, the brake pedal is depressed, or the turn sig-
nal lever is operated, the system may determine that the driver is tak-ing evasive action and the emer-
gency steering assist may not operate.

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)

■Preceding vehicles that the sensor
may not detect correctly
In the following situations, depending on the conditions, if the system cannot pro-
vide sufficient deceleration or accelera- tion is necessary, operate the brake pedal or accelerator pedal.
As the sensor may not be able to cor- rectly detect these types of vehicles, the approach warning ( P.313) may not
operate.
●When a vehicle cuts in front of your
vehicle or changes lanes away from your vehicle extremely slowly or quickly
●When changing lanes
●When a preceding vehicle is driving at a low speed
●When a vehicle is stopped in the same lane as the vehicle
●When a motorcycle is traveling in the same lane as the vehicle
■Conditions under which the system may not operate correctly
In the following situations, operate the brake pedal (or accelerator pedal, depending on the situation) as neces-
sary.
As the sensor may not be able to cor- rectly detect a vehicle, the system may
not operate properly.
●When a preceding vehicle brakes sud-
denly
●When changing lanes at low speeds,
such as in a traffic jam
In situations where the vehicle
approaches a preceding vehicle
and the system cannot provide suf-
ficient deceleration, such as if a
vehicle cuts in front of the vehicle, a
warning display will flash and a
buzzer will sound to alert the driver.
Depress the brake pedal to ensure
appropriate vehicle-to-vehicle dis-
tance.
■Warnings may not occur when
In the following situations, the
warning may not operate even
though the vehicle-to-vehicle dis-
tance is short.
 When the preceding vehicle is
traveling at the same speed or
faster than your vehicle
 When the preceding vehicle is
traveling at an extremely low
speed
 Immediately after the vehicle
speed has been set
 When the accelerator pedal is
depressed
When a curve is detected, the vehi-
cle speed will begin being reduced.
When the curve ends, the vehicle
speed reduction will end.
Depending on the situation, the vehicle
speed will then return to the set vehicle
speed.
In situations where vehicle-to-vehicle
distance control needs to operate, such
as when a preceding vehicle cuts in
front of your vehicle, the curve speed
reduction function will be canceled.
