(d) Micro dust and pollen filter
This vehicle is equipped with a micro
dust and pollen filter mode. When this
mode is activated, air from the vents
will remove pollen on the driver and
passengers.
Push the micro dust and pollen filter
button.
The indicator light and“A/C”come on.
The RECIRCULATED AIR mode is also
turned on at normal outside temperature.
Air is delivered from the instrument panel
vents to the areas near the driver and pas-
sengers to remove pollen on them.
When the interior is purified sufficiently
with fresh air (after about 3 minutes at nor-
mal outside temperature and about 1 min-
ute at low outside temperature), this mode
will be turned off automatically and the indi-
cator light will go out.
When the micro dust and pollen filter is ac-
tivated, this mode will be turned off by
pushing the micro dust and pollen filter but-
ton again. The indicator light will also go
out.
INFORMATION
D Use this mode to remove pollen
quickly carried by the driver or
passengers or through the window
in the days with much pollen.
D Use and push the windshield air
flow button to remove the fog on
the windshield in rainy days.
D Fresh air is delivered even when
the micro dust and pollen filter but-
ton is turned off.

(e) Outside temperature display
Outside temperature is displayed on
the screen.
The displayed temperature ranges from
−40 _C( −40 _F) up to 50 _C (122 _F).
If the temperature shows “ −−” or “E”, take
your vehicle to your Lexus dealer.
In the following situations, the correct out-
side temperature may not be displayed, or
the display may take longer than normal to
change.
DWhen stopped, or driving at low
speeds (less than 12 mph [20 km/h])
DWhen the outside temperature has
changed suddenly (at the entrance/exit
of a garage, tunnel, etc.) (f) Operating tips
DTo help cool down the interior after
parking in the hot sun, drive for the first
few minutes with the windows open.
After the excess heat has blown away,
close the windows.
DMake sure the air inlet grilles in front of
the windshield are not blocked by
leaves or other obstructions.
DIf air flow control is not satisfactory,
check the dashboard vents and rear
vents. (See “(g) Adjusting the position
of and opening and closing the air out-
lets” on page 266.)
DKeep the area under the front seats
clear to allow air to circulate through-
out the vehicle.
DOn cold days, set the fan speed to high
for a minute to help clear the intake
ducts of snow or moisture. This can re-
duce the amount of fogging on the win-
dows.
DWhen driving on dusty roads, close all
windows. If dust thrown up by the ve-
hicle is still drawn into the vehicle after
closing the windows, it is recom-
mended that the air intake control but-
ton be set to the OUTSIDE AIR mode
to take in the fresh air and set the fan
speed selector to any setting except
OFF.
DIf following another vehicle on a dusty
road, or driving in windy and dusty
conditions, it is recommended that the
air intake control button be temporarily
pressed in to the RECIRCULATED AIR
mode, which will close off the outside
passage and prevent outside air and
dust from entering the vehicle interior.

function with the purpose of clearing the
front view.
Pushing this button once again returns the
air flow mode to the last one used.
This button allows the air intake to select
OUTSIDE AIR mode automatically. This is
to clean up the front view more quickly. If
you want to return the setting to RECIR-

control button once again.
Touch “A/C” for dehumidified heating or
cooling. This setting clears the front view
more quickly.
DOn humid days, do not blow cold air on
the windshield −the difference be-
tween the outside and inside tempera-
tures could make the fogging worse. −

If air flow control is not satisfactory,

When outside temperature is cold like a
winter season, air flow temperature from
the center vents, side vents and rear vents
may not be warmed up enough for a while
until that the engine coolant temperature
becomes high enough.
If air flow from the center vents, side vents
and rear vents is not satisfactory, air flow
direction can be changed manually by ad-
justing the vents fin direction or the vents
may be closed.

ter according to the maintenance sched-
ule. In dusty areas or areas with heavy
traffic flow, early replacement may be re-
quired. (For scheduled maintenance infor-
mation, please refer to the “Owner’s
Manual Supplement/Scheduled Mainte-
nance”.)
If air flow from the vents decreases dra-
matically
The filter may be clogged. Check the filter
and replace if necessary.

When an obstacle is detected, the indi-
cator bars will come on or flash, accom-
panied by beeping. How many bars are
lit or flashing depends on the distance
to the obstacle.
When the obstacle is not detected any lon-
ger, beeps will stop sounding and the mul-

The approximate distance to the obstacle
is shown with up to 4 bars on the rear of the
vehicle and up to 3 bars on the front cor-
ners and the rear corners of the vehicle.
CAUTION
To avoid an accident or injury, ob-
serve the following instructions, and
then drive slowly using the brakes
while visually confirming a safe dis-
tance around your vehicle.
DThe sensor detection range is limit-
ed around the bumper. Be sure to
visually confirm safety outside the
sensor detection. For the sensor
detection range, see “ — Detection
range of sensors” on page 284.
DIt might take time for the sensors to
detect obstacles.
DDepending on the shape of the ob-
stacle, indicators or beeps may not
warn you properly, and the detec-
tion range may also be shortened.
DIt might be difficult to hear beeps
due to the volume of audio or air
flow noise of the air conditioning.
