REAR VIEW MONITOR SYSTEM
282
The rear view monitor system assists
the driver by displaying an image of the
view behind the vehicle while backing
up.
To display the rear view image on the
screen, shift the shift lever to “R” when
the “ENGINE START STOP” switch is in
IGNITION ON mode.
If you move the shift lever out of the “R”, the
screen returns to the previous screen. Op-
erating another function of the navigation
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 288.
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 road, such as a
slope.

The diagram shows the detection range of
the sensors. Note that the sensors cannot
detect obstacles that are extremely close
to the vehicle.
The range of the sensors may change de-
pending on the shape of the object etc.
DCertain vehicle conditions and the sur-
rounding environment may affect the
ability of a sensor to correctly detect an
obstacle. Particular instances where
this may occur are listed below.
DThere is dirt, snow or ice on a sen-
sor.
DA sensor is frozen.
DA sensor is covered in any way.
DThe vehicle is leaning considerably
to one side.
DOn an extremely bumpy road, on an
incline, on gravel, or on grass
DThe vicinity of the vehicle is noisy
due to vehicle horns, motorcycle
engines, air brakes of large ve-
hicles, or other loud noises produc-
ing ultrasonic waves.
DThere is another vehicle equipped
with parking assist sensors in the vi-
cinity.
DA sensor is coated with a sheet of
spray or heavy rain.
DThe vehicle is equipped with a fend-
er pole or radio antenna.
DTowing eyelets are installed.
DA bumper or sensor receives a
strong impact.
DThe vehicle is approaching a tall or
right− angled curb.
DIn harsh sunlight or intense cold
weather.
DA non −genuine Lexus suspension
(lowered suspension, etc.) is
installed.
In addition to the examples above, there
are instances in which, because of their
shapes, signs and other objects may be
judged by a sensor to be closer than they
are.
