REAR VIEW MONITOR SYSTEM
286
The rear view monitor system assists
the driver by displaying an image of the
view behind the vehicle while backing
up. The left and right displayed on the
screen are the same as those of the in-
side rear view mirror.
To display the rear view image on the
screen, place the selector lever in the
“R” position when the ignition switch is
in the “ON” position.
If you move the selector lever out of the “R”
position, the screen returns to the previous
screen. Operating another function of the
navigation system will display another
screen.
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
backdoor is not completely closed.
DIf the back of the vehicle is hit, the
position and mounting angle of the
camera may change. Be sure to
have the camera’s position and
mounting angle checked at your
Lexus dealer.
DAs the camera has a water proof
construction, do not detach, disas-
semble or modify it. This may
cause incorrect operation.
DIf the temperature changes rapidly,
such as when hot water is poured
on the vehicle in cold weather, the
system may not operate normally.

APPENDIX

This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However, the accurate posi-
tion may not be shown depending on
the satellite condition, road configura-
tion, vehicle condition or other circum-
stances.
The Global Positioning System (GPS) de-
veloped and operated by the U.S. Depart-
ment of Defense provides an accurate cur-
rent vehicle position, normally using 4 or
more satellites, and in some cases 3 satel-
lites. The GPS system has a certain level
of inaccuracy. While the navigation sys-
tem will compensate for this most of the
time, occasional positioning errors of up to
300 feet (100 m) can and should be expec-
ted. Generally, position errors will be cor-
rected within a few seconds.
When your vehicle is receiving signals
from the satellites, the “GPS” mark ap-
pears at the top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle
position on the map display. Tunnels, tall
buildings, trucks, or even the placement of
objects on the instrument panel may ob-
struct the GPS signals.
The GPS satellites may not send signals
due to repairs or improvements being
made to them.
Even when the navigation system is re-
ceiving clear GPS signals, the vehicle
position may not be shown accurately or
inappropriate route guidance may occur in
some cases.
NOTICE
The installation of window tinting
may obstruct the GPS signals. Most
window tinting contains some metal-
lic content that will interfere with GPS
signal reception of the antenna in the
instrument panel. We advise against
the use of window tinting on vehicles
equipped with navigation systems.

INFORMATION
If your vehicle cannot receive GPS

on setting the current position cal-
ibration, see page 112.
(b) Inappropriate route guidance may
occur in the following cases:
DWhen turning at an intersection off the
designated route guidance.
DIf you set more than one destination but
skip any of them, auto reroute will dis-
play a route returning to the destination
on the previous route.
DWhen turning at an intersection for
which there is no route guidance.
DWhen passing through an intersection
for which there is no route guidance.
DDuring auto reroute, the route guid-
ance may not be available for the next
turn to the right or left.
DIt may take a long time to operate auto
reroute during high speed driving. In
auto reroute, a detour route may be
shown.
DAfter auto reroute, the route may not be
changed.
DAn unnecessary U −turn may be shown
or announced.
DA location may have multiple names
and the system will announce one or
more.
DSome routes may not be searched.
DIf the route to your destination includes
gravel, unpaved roads or alleys, the
route guidance may not be shown.
DYour destination point might be shown
on the opposite side of the street.
