●This navigation system uses tire
turning data and is designed to
work with factory- specified tires
for the vehicle. Ins talling tires that
are larger or smaller than the orig-
inally equipped diameter may
cause inaccurate display of the
current position. The tire pressure
also affects the diameter of the
tires, so make sure that the tire
pressure of all 4 tires is correct.

1747-1. Rear view monitor system
7-1.Rear view monitor system
●The screen illustrations used in
this text are intended as exam-
ples, and may differ from the
image that is actually displayed on
the screen.
The rear view monitor system is
a supplemental device intended
to assist the driver when back-
ing up. When backing up, be
sure to visually check all around
the vehicle both directly and
using the mirrors before pro-
ceeding. If you do not, you may
hit another vehicle, and could
possibly cause an accident.
Pay attention to the following
precautions when using the rear
view monitor system.
Rear view monitor sys-
tem
The rear view monitor sys-
tem assists the driver by
displaying an image of the
view behind the vehicle with
fixed guide lines on the
screen while backing up, for
example while parking.
Driving precautions
WA R N I N G
●Never depend on t he rear view
monitor system entirely when
backing up. The image and the
position of the guide lines dis-
played on the screen may differ
from the actual state.
Use caution, just as you would
when backing up any vehicle.
●Be sure to back up slowly,
depressing the brake pedal to
control vehicle speed.
●The instructions given are only
guide lines. When and how
much to turn the steering wheel
will vary according to traffic con-
ditions, road surface condi-
tions, vehicle condition, etc.
when parking. It is necessary to
be fully aware o f this before
using the rear view monitor sys-
tem.
●When parking, be sure to check
that the parking space will
accommodate your vehicle
before maneuvering into it.
●Do not use the rear view moni-
tor system in t he following
cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emer- gency tires
• When the tailgate is not closed completely
• On roads that are not flat or straight, such as curves or
slopes
●In low temperatures, the screen
may darken or the image may
become faint. The image could
distort when the vehicle is mov-
ing, or you may become unable
to see the image on the screen.
Be sure to visually check all
around the vehicle both directly
and using the mirrors before
proceeding.
●If the tire sizes are changed, the
position of the fixed guide lines
displayed on the screen may
change.
