the set speed will be set to
approximately 20 mph [30 km/h].)
■Accelerating after setting the
vehicle speed
The vehicle can accelerate by oper-
ating the accelerator pedal. After
accelerating, the set speed
resumes. However, during vehicle-
to-vehicle distance control mode,
the vehicle spee d may decrease
below the set speed in order to
maintain the distance to the preced-
ing vehicle.
■When the vehicle stops while
follow-up cruising
●Pressing the “+RES” switch while
the vehicle ahead stops will
resume follow-up cruising if the
vehicle ahead starts off within
approximately 3 seconds after the
switch is pressed.

ahead
In the case of the following and
depending on the conditions, oper-
ate the brake pedal when decelera-
tion of the system is insufficient or
operate the accelerator pedal when
acceleration is required.
As the sensor may not be able to
correctly detect these types of vehi-
cles, the approach warning
(  P.341) may not be activated.

PKSB (Parking Sup-
port Brake)*
The Parking Support Brake
system consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
possibility of a collision
with a detected object is
high, a warning operates to
urge the driver to take eva-
sive action. If the system
determines that the possi-
bility of a collision with a
detected object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the
collision.

WARNING
■Cautions regarding the use of
the system
Do not overly rely on the system,
as doing so may lead to an acci-
dent.
Always drive while checking the
safety of the surroundings of the
vehicle.
Depending on the vehicle and
road conditions, weather, etc., the
system may not operate.
The detection capa bilities of sen-
sors and radars are limited.
Always drive while checking the
safety of the surroundings of the
vehicle.
●The driver is solely responsible
for safe driving. Always drive
carefully, taking care to observe
your surroundings. The Parking
Support Brake system is
designed to provide support to
lessen the severity of collisions.
However, it may not operate in
some situations.
●The Parking Support Brake sys-
tem is not designed to stop the
vehicle completely. Addition-
ally, even if the system has
stopped the vehicle, it is neces-
sary to depress the brake pedal
immediately as brake control
will be canceled after approxi-
mately 2 seconds.
●It is extremely dangerous to
check the system operations by
intentionally driving the vehicle
into the direction of a wall, etc.
Never attempt such actions.
■When to disable the Parking
Support Brake
In the following situations, disable
the Parking Support Brake as the
system may operate even though
there is no poss ibility of a colli-
sion.
●When inspecting the vehicle
using a chassis roller, chassis
dynamo or free roller.
●When loading the vehicle onto a
boat, truck or other transport
vessel.
●If the suspension has been
modified or tires of a size other
than specified are installed.
●If the front of the vehicle is
raised or lowered due to the
carried load.
●When equipment that may
obstruct a sensor is installed,
such as a towing eyelet, bumper
protector (an additional trim
strip, etc.), bicycle carrier, or
snow plow.
●When using automatic car
washing devices.
●If the vehicle cannot be driven in
a stable manner, such as when
the vehicle has been in an acci-
dent or is malfunctioning.
●When the vehicle is driven in a
sporty manner or off-road.
●When the tires are not properly
inflated.
