RCTA buzzer
If a vehicle approaching from the
RCTA (Rear Cross Traf-

The RCTA function uses the
BSM rear side radar sensors
installed behind the rear
bumper. This function is
intended to assist the driver
in checking areas that are
not easily visible when
backing up.

Cautions regarding the use of
the system
There is a limit to the degree of
recognition accuracy and control
performance that this system can
provide, do not overly rely on this
system. The driver is always
responsible for paying attention to
the vehicle’s surroundings and
driving safely. (

■
Cautions regarding the use of
the function
The driver is solely responsible for
safe driving. Always drive safely,
taking care to observe your sur-
roundings.
The RCTA function is only a sup-
plementary function which alerts
the driver that a vehicle is
approaching from the right or left
at the rear of the vehicle. As the
RCTA function may not function
correctly under certain condi-
tions, the driver’s own visual con-
firmation of safety is necessary.
Over reliance on this function may
lead to an accident resulting
death or serious injury.

■
Operation of the RCTA function
The RCTA function uses rear side radar sensors to detect vehicles
approaching from the right or left at the rear of the vehicle and alerts
the driver of the presence of such vehicles by flashing the outside
rear view mirror indicators and sounding a buzzer.

Example:
■
The RCTA function is opera-

The RCTA function operates when
all of the following conditions are
met:
●
The power switch is in ON.
●
The RCTA function is on.
●
The shift lever is in R.
●
The vehicle speed is approxi-
mately 5 mph (8 km/h) or less.
●
The approaching vehicle speed is
between approximately 5 mph (8
km/h) and 18 mph (28 km/h).
■
Conditions under which the
system will not detect a vehicle
The RCTA function is not designed
to detect the following types of vehi-
cles and/or objects:
●
Vehicles approaching from directly
behind
●
Vehicles backing up in a parking
space next to your vehicle
●
Vehicles that the sensors cannot
detect due to obstructions
●
Guardrails, walls, signs, parked
vehicles and similar stationary
objects
*
●

parking spaces next to your vehi-
cle

and approaching vehicle gets too
close

: Depending on the conditions,
detection of a vehicle and/or
object may occur.

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 col-
lision.

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 capabilities 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. Additionally,
even if the system has stopped
the vehicle, it is necessary to
depress the brake pedal imme-
diately as brake control will be
canceled after approximately 2
seconds.
