air mode may be automatically
switched to in accordance with the
temperature setting and the inside
temperature.
D Window defogger feature
Recirculated air mode may auto-
matically switch to outside air
mode in situations where the win-
dows need to be defogged.
D When outside air temperature is
below 32 _F(0 _C)
The cooling and dehumidification
function may not operate even
when “A/C” is on.
D When the indicator light on “A/C”
flashes
Touch “A/C” to turn off the air con-

mirror defogging
To turn the electric rear window and
outside rear view mirror defogger on,
push the button above.
The “ENGINE START STOP” switch must
be in IGNITION ON mode.
The thin heater wires on the inside of the

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.
INFORMATION
D In order to prevent the window
from fogging up when the outside
air is cold, the following may oc-
cur:
D Outside air mode does not
switch to recirculated air mode.
D The air conditioning system op-
erates automatically.
D The operation cancels after 1
minute.
D In rainy weather, the windows may

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.

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.
