Interior features
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and the
ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow immedi-
ately after the “AUTO” button is pressed or “AUTO” is selected.
■When the outside temperature exceeds 75 °F (24 °C) and the air conditioning sys-
tem is on
●In order to reduce the air conditioning power consumption, the air conditioning
system may switch to recirculated air mode automatically.
This may also reduce fuel consumption.
●Recirculated air mode is selected as a default mode when the “START STOP
ENGINE” <“POWER”> switch is turned to IGNITION ON <ON> mode.
●It is possible to switch to outside air mode at any time by pressing .
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Selecting
“A/C” on the option control screen will dehumidify the air from the outlets and
defog the windshield effectively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
■Windshield fog detection function (if equipped)
When automatic mode is set, the humidity sensor (→P. 476) detects fog on the
windshield and controls the air conditioning system to prevent fog.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set to
the recirculated air mode. This is effective in preventing outside air from entering
the vehicle interior. During cooling operation, setting the recirculated air mode will
also cool the vehicle interior effectively.
●Outside/recirculated air mode may automatically switch depending on the tem-
perature setting or the inside temperature.
■When the outside temperature is low
The dehumidification function may not operate even when “A/C” on the option con-
trol screen is selected.

The “START STOP ENGINE” <“POWER”> switch is in IGNITION ON <ON>
mode.
■Operating the rear sunshade after the engine <hybrid system> is turned off
The rear sunshade can be operated for approximately 1 minute even after the
“START STOP ENGINE” <“POWER”> switch is turned to ACCESSORY mode or
turned off.
■Reverse operation feature
To ensure adequate rear visibility, the rear sunshade automatically lowers when the
shift lever is shifted to R.

●The button is pressed again.*
●Shift the shift lever into P.
●The shift lever is shifted out of R, and the vehicle reaches a speed of 9 mph
(15 km/h).
If the engine <hybrid system> is off when the rear sunshade has been lowered due
to the reverse operation feature, it will not be raised even when the engine
<hybrid system> is turned on again and the vehicle reaches a speed of 9 mph (15
km/h). To raise the sunshade again, press the button.
*: Occasionally, the reverse function may not be carried out after the switch has been pressed. Repeat the above operation to operate the function.

When the “START STOP ENGINE” <“POWER”> switch is turned to
IGNITION ON <ON> mode, the red indicator light comes on for 2 sec-
onds then turns off. Afterward, the green indicator light comes on, indicat-
ing that the service is active.
The following indicator light patterns indicate specific system usage con-
ditions:
●Green indicator light on = Active service
●Green indicator light flashing = Safety Connect call in process
●Red indicator light (except at vehicle start-up) = System malfunction
(contact your Lexus dealer)
●No indicator light (off) = Safety Connect service not active
■Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision, the
system is designed to automatically call the response center. The
responding agent receives the vehicle’s location and attempts to speak
with the vehicle occupants to assess the level of emergency. If the occu-
pants are unable to communicate, the agent automatically treats the
call as an emergency, contacts the nearest emergency services pro-
vider to describe the situation, and requests that assistance be sent to
the location.

7-2. Maintenance
■Repair and replacement
It is recommended that genuine Lexus parts be used for repairs to ensure perfor-
mance of each system. If non-Lexus parts are used in replacement or if a repair shop
other than a Lexus dealer performs repairs, confirm the warranty coverage.
■Resetting the message indicating maintenance is required (U.S.A. only)
After the required maintenance is performed according to the maintenance sched-
ule, please reset the maintenance data.
To reset the data, follow the procedure described below:Switch the display to the trip meter “A” ( →P. 98) when the engine <hybrid system>
is running <operating>.
Turn the “START STOP ENGINE” <“POWER”> switch off.
While pressing the “ODO TRIP” button ( →P. 98), turn the “START STOP
ENGINE” <“POWER”> switch to the IGNITION ON <ON> mode (do not start
the engine <hybrid system> because otherwise the reset mode will be canceled).
■Allow inspection and repairs to be performed by a Lexus dealer
●Lexus technicians are well-trained specialists and are kept up to date with the latest
service information. They are well informed about the operations of all systems on
your vehicle.
●Keep a copy of the repair order. It proves that the maintenance that has been per-
formed is under warranty coverage. If any problem should arise while your vehicle
is under warranty, your Lexus dealer will promptly take care of it. The message shown in the illustration will
appear on the display.
Continue to press and hold the button until
the trip meter displays “000000”.

Maintenance and care
◆Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by your Lexus dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to expose the fabric,
and bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size or loca-
tion of a cut or other damage
If you are not sure, consult with your Lexus dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not registered, the
tire pressure warning system will not work properly. After driving for about 20 min-
utes, the tire pressure warning light blinks for 1 minute and stays on to indicate a sys-
tem malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if it has sel-
dom or never been used or damage is not obvious.
■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation pressure
checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
■When rotating the tires
Make sure that the “START STOP ENGINE” <“POWER”> switch is off. If the tires are
rotated while the “START STOP ENGINE” <“POWER”> switch is in IGNITION ON
<ON> mode, the tire position information will not be updated.
If this accidentally occurs, either turn the “START STOP ENGINE” <“POWER”>
switch to off and then to IGNITION ON <ON> mode, or initialize the system after
checking that the tire pressure is properly adjusted.
