The defoggers will automatically turn off
after 15 to 60 minutes. The operation time
changes according to the ambient temper-
ature and vehicle speed.
If further defrosting or defogging is de-
sired, simply actuate the switch again.
When the surface has cleared, push the
button once again to turn the defogger off.
Continuous use may cause the battery to
discharge, especially during stop−and− go
driving. The defogger is not designed to
dry rain water or to melt snow.
If the outside rear view mirrors are heavily
coated with ice, use a spray de −icer before
operating the system.
NOTICE
DWhen cleaning the inside of the
rear window, be careful not to
scratch or damage the heater wires
or connectors.
DTo prevent the battery from being
discharged, turn the switch off
when the engine is not running.
(g) Micro dust and pollen filter
Push the micro dust and pollen filter
button.
Outside air mode switches to recirculated
air mode. Pollen is removed from the air
flows to the upper part of the body.
Usually the system will turn off automati-
cally after approximately 3 minutes.
To stop the operation, push the micro dust
and pollen filter button again.

D The air conditioning system op-
erates automatically.

NOTICE
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.
DDo not allow organic solvent, car
wax, window cleaner or glass coat
to adhere to the camera. If this hap-
pens, wipe it off as soon as pos-
sible.
DWhen replacing the tires, please
consult your Lexus dealer. If you
replace the tires, the area dis-
played on the screen may change.
INFORMATION
If the camera lens becomes dirty, it
cannot transmit a clear image. If wa-
ter droplets, snow, or mud adhere to
the lens, rinse with water and wipe
with a soft cloth. If the lens is ex-
tremely dirty, wash it with a mild
cleanser and rinse.
DArea displayed on screen
Image is displayed approximately level
on screen.

The area detected by the camera is limi-
ted. The camera does not detect objects
which are close to either corner of the
bumper or under the bumper.

APPENDIX
370
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 case 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.
