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

NOTICE
DIf the front of the vehicle is hit, the
camera’s position and mounting
angle may change. Contact your
Lexus dealer.
DRapid temperature changes, such
as when hot water is poured on the
vehicle in cold weather, may cause
the system to function abnormally.
DWhen replacing the tires, please
consult your Lexus dealer. If you
replace the tires, the area dis-
played on the screen may change.
DIf the camera lens is dirty, it cannot
transmit a clear image. Rinse with
water and wipe with a soft cloth. If
extremely dirty, wash with a mild
cleanser and rinse.
INFORMATION
DThe area displayed on the screen
may vary according to vehicle sta-
tus or road conditions.
D Due to the property of the front
camera lens, the perceived dis-
tance from images that appear on
the screen differs from the actual
distance.
D In the following cases, it may be-
come difficult to see the images on
the screen, but this is not a mal-
function:
D In the dark (for example, at night)
D When the temperature near the
lens is high or low
D When there are water droplets
on the camera lens, or when hu-
midity is high (for example,
when it rains)
D When foreign matter such as
mud is stuck to the front camera
D When the sun or the beam of
headlights is shining directly
into the camera lens
D The following symptoms may oc-
cur, but do not indicate a malfunc-
tion:
D The camera may fog up when hu-
midity is high (for example,
when it rains).
D When driving at night, ambient
lights such as the lights of the
vehicles ahead and building
lighting may be reflected into the
image.
D The center or four corners of the
image may decrease in definition.
D As the procedure is the same, fol-
low the instructions for navigation
screen adjustment to adjust the
wide view front monitor. (See page
36.)

by the circumference difference between
the old and new tires. If this procedure is
not performed when the tires are replaced,
the current vehicle position mark may be
incorrectly displayed.

After replacing a tire, implement the op-
eration described in the “TIRE
CHANGE CALIBRATION”. (See page
332.)
This navigation system uses tire turning
data and is designed to work with factory−
specified tires for your vehicle. Installing
tires that are larger or smaller than the orig-
inally equipped diameter may cause inac-
curate display of the vehicle’s position.
The tire pressure also affects the diameter
of the tires so please make sure the tire
pressure of all four tires is correct. This system uses the maps of DENSO.
