▼360° View Monitor
The 360°View Monitor consists of the
following functions which assist the driver
in checking the area surrounding the
vehicle using various indications in the
center display and a warning sound while
the vehicle is being driven at low speeds
or while parking.
To p v i e w
The top view display
s an image of the
vehicle from directly above on the
center display by combining the images
taken from the 4 cameras set on all sides
of the vehicle. The top view displays on
the right side of the screen when the
front view or rear view screen is being
displayed. The top view assists the
driver in checking the area surrounding
the vehicle when the vehicle is moving
forward or in reverse.
Front view/front wide view
The image from the fr ont of the vehicle
is displayed on the center display.
The view from the front assists the
driver in checking the front of the
vehicle by displaying guide lines on the
displayed image taken from the front of
the vehicle.
Side view
The images taken from the front left and
right sides of the vehicle are displayed
on the center display.
The side view assists the driver in
checking the front sides of the vehicle
by displaying guide lines on the
displayed image taken from the front
left and right sides of the vehicle.
Rear view/rear wide view
The image from the rear of the vehicle is
displayed on the center display.
The image from the rear assists the
driver in checking the rear of the vehicle

the vehicle.
Parking sensor
If there are any obstructions near the
vehicle while the top view/side view is
displayed, an obstruction detection
indication turns on around the bumper in
the center display.
The parking sensors use ultrasonic
sensors to detect obstructions around the
vehicle when the vehicle is driven at low
speeds, such as during garage or parallel
parking, and notifie s the driver of the
approximate distance from the vehicle to
the surrounding obstruction using sound
and an obstruction detection indication.
Refer to Parking Sensor System on page
4-235.
Front Cross Traffic Alert (FCTA)
If there is the possibi lity of a collision
with an approaching vehicle while the
front view/front wide view/side view is
displayed, a warning is displayed on the
center display.
The Front Cross Traffic Alert (FCTA) is
designed to assist the driver in checking
both sides of the vehicle when the
vehicle starts to drive at an intersection.

WA R N I N G
Always confirm the safety of the area
around the vehicle with the mirrors and
directly with your eyes when driving:
The 360°View Monitor is an auxiliary device
which assists the driver in checking the
safety of the area around the vehicle.
The shooting range of the cameras and
detection range of the sensors are limited.
For example, the areas in black at the front
and rear of the vehicle image and the
seams where each of the camera images
merge are blind spots where an obstruction
may not be visible. In addition, the
extended vehicle width lines and projected
vehicle path lines are only to be used as
references, and the images on the screen
may differ from the actual conditions.
CAUTION
 Do not use the 360°View Monitor under
any of the following conditions.
 Icy or snow-covered roads.
 Tire chains or a te mporary spare tire is
installed.
 The front doors or the rear doors is not
fully closed.
 The vehicle is on a road incline.
 The door mirrors are retracted.
 Do not hit the front/rear camera, front/
rear bumper, and door mirrors forcefully.
The camera position or installation angle
may shift.
 The cameras are of a waterproof
structure. Do not disassemble, modify, or
remove a camera.
