REAR VIEW MONITOR SYSTEM
290
The rear view monitor system assists
the driver by displaying an image of the
view behind the vehicle while backing
up. The image is displayed in reverse
on the screen. This allows the image to
appear in the same manner as that of
the rear view mirror.
To display the rear view image on the
screen, shift the shift position to “R”
when the “POWER” switch is in ON
mode.
If you move the shift position out of the “R”,
the screen returns to the previous screen.
Operating another function of the naviga-
tion system will display another screen.
Vehicles with intuitive parking assist−
sensor — when the intuitive parking as-
sist− sensors are turned on and an ob-
stacle is detected in front of or behind
your vehicle, a warning appears on the
right top of the rear view monitor. For
details, see “Intuitive parking assist” on
page 304.
The rear view monitor system is a supple-
ment device intended to assist back up.
When backing up, be sure to check behind
and all around the vehicle visually.CAUTION
DNever depend on the rear view
monitor system entirely when
backing up. Always make sure
your intended path is clear.
Use caution, just as you would
when backing up any vehicle.
DNever back up while looking only at
the screen. The image on the
screen is different from actual
conditions. Depicted distances
between objects and flat surfaces
will differ from actual distance. If
you back up while looking only at
the screen, you may hit a vehicle, a
person or an object. When backing
up, be sure to check behind and all
around the vehicle visually and
with mirrors before proceeding.
DDo not use the system when the
trunk is not completely closed.
DUse your own eyes to confirm the
vehicle’s surroundings, as the dis-
played image may become faint or
dark, and moving images will be
distorted, or not entirely visible
when the outside temperature is
low. When backing up, be sure to
check behind and all around the ve-
hicle visually and with mirror be-
fore proceeding.
DDo not use the system in the follow-
ing cases:
DOn icy or slick road surfaces, or
in snow.
DWhen using tire chains or emer-
gency tires.
DOn an uneven or indirect road,
such as a slope or curve.

WIDE VIEW FRONT MONITOR SYSTEM
296
The wide view front monitor uses a super−
wide angle lens to display on screen the
areas to the left and right of the vehicle and
the blind spots to the front of the vehicle.
This system helps the driver check for ap-
proaching cars, bicycles and pedestrians
when at intersections with poor visibility.
CAUTION
DAlways make sure to check all
around the vehicle with your own
eyes when driving.
DDue to the property of the front
camera lens, the position of and
distance to people or objects dis-
played differs from actual position
and distance.
DNever depend on the front monitor
only. Use caution just as you would
when driving any other vehicle.
DNever drive while looking only at
the screen as the image on the
screen is different from actual con-
ditions. If you drive while looking
only at the screen, you may hit a
person or an object, resulting in an
accident. When driving, be sure to
check the vehicle’s surroundings
with your own eyes and the ve-
hicle’s mirrors.
DWhen the outside temperature is
low, the displayed image may be-
come faint or dark. Moving images
will be distorted or not entirely vis-
ible, so be sure to check the ve-
hicle’s surroundings with your
own eyes and the vehicle’s mirrors
while driving.
DThe displayed image may be darker
and moving images may be slightly
distorted when the system is cold.
DDo not use the front monitor in the following cases:
DOn icy or slick road surfaces,or
in snow
DWhen using tire chains or emer-
gency tires
DWhen the hood or the front pas-
senger door is not completely
closed
DOn roads that are not flat or di-
rect, such as slopes or curves
