If air flow control is not satisfactory,
check the center vents, side vents and
rear vents. They may be opened or
closed as shown.
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.

(h) Checking and replacing the air
conditioning filter
The air conditioning filter information
label is placed in the glove box as
shown and indicates that a filter has
been installed.
The air conditioning filter, in addition to re-
moving odors, prevents dust and pollen
from entering the vehicle through the air
conditioning vent.
The air conditioning filter is behind the
glove box.
The air conditioning filter may clog after
long use. The filter may need to be re-
placed if the air flow of the air conditioner
and heater experiences extreme reduc-
tions in operating efficiency, or if the win-
dows become to fog up easily.
If the symptoms of air conditioning efficien-
cy problems occur, contact your nearest
Lexus dealer to have the filter checked and
replaced.
To maintain the air conditioning efficiency,
replace the air conditioning filter according
to the maintenance schedule. In dusty
areas or areas with heavy traffic flow, such
as inner city or desert areas, early replace-
ment may be required. (For scheduled
maintenance information, please refer to
the “Owner’s Manual Supplement/Sched-
uled Maintenance”.)

1. Set the air conditioning system to
RECIRCULATED AIR mode.
The air conditioning filter case cannot be
removed with the OUTSIDE AIR mode.
2. Turn the “ENGINE START STOP”
switch off.
When you replace the filter, be sure to turn
off the fan.
3. Open the glove box. Lift and remove
the partition.
4. Remove the filter cover.
5. Remover the filter case as shown.
6. Remove the filter from the filter
case.
7. Inspect the filter on the surface.
If it is the just moderately dusty, it may be
cleaned by blowing compressed air from
the reverse surface. Do not wash or oil the
filter.
If it is dirty, it should be replaced.
When installing the filter in the filter
case, keep the arrow pointing up.

INFORMATION
The air conditioning filter should be
installed properly in position. The
use of air conditioning with the filter
removed may cause deteriorated
dustproof performance and then af-
fect air conditioning performance.

play)

view monitor system)
(See “ — Rear view monitor dis-
play” on page 287.)
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-
ti− information display and the screen will
return to the previous display.
The volume of the beeps and the display
on the screen can be changed. See “ —
Setting the Lexus parking assist −sensor”
on page 289.

sors
2Detection by rear corner sensors
3Detection by back sensors
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.

When obstacles are detected on the
front and rear of the vehicle at the same
time; the multi−information display and
screen illuminate their relevant indica-
tor bars. And beeps are as follows:
1Obstacles detected on the front
and rear of the vehicle are not in
areas where continuous beeping
should sound:
The warning for the obstacle closer to the
vehicle will be issued. The above illustra-
tion indicates the obstacle detected by the
back sensors is closer to the vehicle. So,
the warning for the obstacle detected by
the back sensors will be given.
2The obstacle detected on the front
or rear of the vehicle is in an area
where continuous beeping should
sound:
If the possibility of collision with the ob-
stacle is high as shown, the parking as-
sist− sensor warns the driver by continu-
ous beeping (repeating 7 intermittent
beeps and one longer beep as one cycle).
3Both obstacles detected on the
front and rear of the vehicle are in
areas where continuous beeping
should sound:
If the possibility of collision with the ob-
stacles is very high as shown, the parking
assist− sensor warns the driver by continu-
ous beeping (repeating 3 quick beeps and
one longer beep as one cycle).
CAUTION
It might be difficult to hear beeps due
to the volume of audio or air flow
noise of the air conditioning. To
avoid an accident or injury, drive
slowly using the brakes while visual-
ly confirming a safe distance around
your vehicle.

APPENDIX
294
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.
