REAR VIEW MONITOR SYSTEM
284
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 the “R”
position 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 290.
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.

TIRE CHANGE CALIBRATION
The tire change calibration function will be
used when replacing the tires. This func-
tion will adjust the miscalculation caused
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.
To perform a distance calibration pro-
cedure, touch “Tire Change” on the
“Calibration” screen.
The message appears and the quick dis-
tance calibration is automatically started.
A few seconds later, a map will be dis-
played.

After replacing a tire, implement the op-
eration described in the “TIRE
CHANGE CALIBRATION”. (See page
315.)
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.
