“” button.
If quick heating or cooling is desired —
“LO” appears when you hold it until maxi-
mum cooling (decrease), and “HI” appears
when you hold it until maximum warning
(increase).
“TEMP” button — Changes the tempera-
ture on the driver and passenger sides si-
multaneously or the driver side only.
“PASSENGER TEMP” button —
Changes the temperature settings sepa-
rate from the driver side.
“DUAL” —
This button is used to set the temperatures
independently for the driver ’s seat and
front passenger seat.

REAR VIEW MONITOR SYSTEM
272
The rear view monitor system assists
the driver by displaying an image of the
view behind the vehicle while backing
up. The image is displayed in reverse
on the screen. This allows the image to
appear in the same manner as that of
the rear view mirror.
To display the rear view image on the
screen, shift the shift lever to “R” (auto-
matic transmission) or reverse (manual
transmission) when the “ENGINE
START STOP” switch is in IGNITION ON
mode.
If you move the shift lever out of the “R”
(automatic transmission) or reverse
(manual transmission), the screen returns
to the previous screen. Operating another
function of the navigation system will dis-
play another screen.
Vehicles with Lexus parking assist−sen-
sor — when the Lexus parking assist −
sensors are turned on and an obstacle is
detected in front of or behind your ve-
hicle, a warning appears on the right top
of the rear view monitor. For details, see
“Lexus parking assist −sensor” on page
278.
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
trunk 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.

LEXUS PARKING ASSIST−SENSOR
278
The Lexus parking assist−sensor is a
warning system used when parking the
vehicle at low speed (e.g. into a garage).
It uses an ultrasonic sensor, which
checks the approximate distance to an
obstacle. It will inform you of the
approximate distance to an obstacle by
displaying information on the multi −in-
formation display and the screen, and
with beeping sounds.
1Front corner sensors
There is one of these installed on each cor-
ner of the front bumper, they inspect ob-
stacles and will sound a warning depend-
ing on the distance to the obstacle. (See
“ — Front corner sensors” on page 280.)
2Rear corner sensors
There is one of these installed on each cor-
ner of the rear bumper, they inspect ob-
stacles and will sound a warning depend-
ing on the distance to the obstacle. (See
“ — Rear corner sensors” on page 281.)
3Back sensors
There are two of these installed near the
center of the rear bumper, they inspect ob-
stacles and will sound a warning depend-
ing on the distance to the obstacle. (See
“ — Back sensors” on page 282.)
To use the parking assist −sensor, with
the “ENGINE START STOP” switch in
IGNITION ON mode, push “
”or“”
of the satellite switch to select the park-
ing assist− sensor and then push the
ON/OFF button. Selecting the parking
assist− sensor and pushing the ON/OFF
button of the satellite switch again will
turn the parking assist −sensor off.
When you turn on the parking assist −sen-
sor, the indicator light in the instrument
cluster comes on and a beep sounds for
one second, indicating that the parking as-
sist− sensor is turned on.
The parking assist −sensor will remain on
even after turning the “ENGINE START
STOP” switch to OFF and then to IGNI-
TION ON mode with the main switch on.
However, a beep does not sound at this
time.
If an error is detected in the Lexus parking
assist− sensor while self −checking, beeps
sound and a warning appears in the multi −
information display and on the screen. For
details, see “ — Lexus parking assist −sen-
sor failure warning” on page 285.

2About 0.8 ft. (25 cm) to about

3Less than about 0.8 ft. (25 cm)
The front corner sensor only operates
when the vehicle speed is less than
about 6 mph (10 km/h). It checks the
approximate distance to obstacles at
an angle to the front of the vehicle, and
sounds a warning depending on the
distance. This sensor does not operate
if the transmission is in “P” position
(automatic transmissions), or the park-
ing brake is set (manual transmis-
sions). Multi−
information display:
The indicator bars come on depending on
the distance to the obstacle and flash
when the distance between the vehicle
and the obstacle is less than about 0.8 ft.
(25 cm).
Touch screen:
When an obstacle is detected, indicator
bars illuminate in yellow. The number of
the indicator bars reduces as the vehicle
gets closer to the obstacle, and turn red
when the distance between the vehicle
and obstacle is less than 0.8 ft. (25 cm).
Beeps:
As distance to the obstacle gets closer, the
interval of the intermittent sound gets
shorter, and then finally changes to a con-
tinuous sound when the distance between
the vehicle and the obstacle is less than
about 0.8 ft. (25 cm).
CAUTION
When you move your vehicle, be sure
to visually confirm a safe distance
around your vehicle and drive slowly,
or an accident or injury may result.

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.
