■Daytime running light system
●The daytime running lights illuminate
using the same lights as the parking lights
and illuminate brighter than the parking
lights.
●To make your vehicle more visible to
other drivers during daytime driving, the
daytime running lights turn on automati-
cally when all of the following conditions
are met. (The daytime running lights are
not designed for use at night.)
• The engine is running
• The parking brake is released
• The headlight switch is in the or
* position
*: When the surroundings are bright
The daytime running lights remain on after
they illuminate, even if the parking brake is
set again.
●For the U.S.A.: Daytime running lights
can be turned off by operating the switch.
●Compared to turning on the headlights,
the daytime running light system offers
greater durability and consumes less
electricity, so it can help improve fuel
economy.
■Headlight control sensor
The sensor may not function properly if an
object is placed on the sensor, or anything

Close all the doors and windows,
and turn the engine switch off.
 Confirm the type of fuel.
■Fuel types
 P.382
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehi-
cle has a fuel tank opening that only accom-
modates the special nozzle on unleaded
fuel pumps.
■If the malfunction indicator lamp illumi-
nates
The malfunction indicator lamp may illumi-
nate erroneously if refueling is performed
repeatedly when the fuel tank is nearly full.
Opening the fuel tank cap
Perform the following steps to open
the fuel tank cap:
Before refueling the vehicle
WARNING
■When refueling the vehicle
Observe the following precautions while
refueling the vehicle. Failure to do so may
result in death or serious injury.
●After exiting the vehicle and before
opening the fuel door, touch an
unpainted metal surface to discharge
any static electricity. It is important to
discharge static electricity before refu-
eling because sparks resulting from
static electricity can cause fuel vapors
to ignite while refueling.
●Always hold the grips on the fuel tank
cap and turn it slowly to remove it.
A whooshing sound may be heard
when the fuel tank cap is loosened.
Wait until the sound cannot be heard
before fully removing the cap. In hot
weather, pressurized fuel may spray
out the filler neck and cause injury.
●Do not allow anyone that has not dis-
charged static electricity from their
body to come close to an open fuel
tank.
●Do not inhale vaporized fuel.
Fuel contains substances that are
harmful if inhaled.
●Do not smoke while refueling the vehi-
cle.
Doing so may cause the fuel to ignite
and cause a fire.
●Do not return to the vehicle or touch
any person or object that is statically
charged.
This may cause static electricity to
build up, resulting in a possible ignition
hazard.
■When refueling
Observe the following precautions to
prevent fuel overflowing from the fuel
tank:
●Securely insert the fuel nozzle into the
fuel filler neck.
●Stop filling the tank after the fuel noz-
zle automatically clicks off.
●Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling.
Doing so may damage the vehicle, such
as causing the emission control system to
operate abnormally or damaging fuel
system components or the vehicle’s
painted surface.

Interior features
■Defogging the windshield
Defoggers are used to defog the wind-
shield and front side windows.
Press the windshield defogger switch.
Set the outside/recirc ulated air mode but-
ton to outside air mode if the recirculated
air mode is used. (It may switch automati-
cally.)
To defog the windshield and the side win-
dows early, turn the air flow and tempera-
ture up.
To return to the previous mode, press the
windshield defogger switch again when the
windshield is defogged.
When the windshield defogger switch is
on, the indicator illuminates on the wind-
shield defogger switch.
■Defogging the rear window and
outside rear view mirrors
Defoggers are used to defog the rear
window, and to remove raindrops, dew
and frost from the outside rear view
mirrors.
Press the rear window and outside rear
view mirror defoggers switch.
The defoggers will automatically turn off
after a period of time.
When the rear window and outside rear
view mirror defoggers switch is on, the
indicator illuminates on the rear window
and outside rear view mirror defoggers
switch.
■When the outside temperature exceeds
75°F (24°C) and the air conditioning
system 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 engine switch is
turned to IGNITION ON mode.
●It is possible to switch to outside air mode
at any time by pressing the outside/recir-
culated air mode switch.
■Fogging up of the windows
The windows will easily fog up when the
humidity in the vehicle is high. Turning A/C
switch (“A/C”) on will dehumidify the air
from the outlets and defog the windshield
effectively.
●If you turn A/C swit ch (“A/C”) off, the
windows may fog up more easily.
●The windows may fog up if the recircu-
lated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up by the
vehicle is still drawn into the vehicle after
closing the windows, it is recommended
that the air intake mode be set to outside air
mode and the fan speed to any setting
except off.
■Outside/recirculated air mode
●Setting to the recirculated air mode tem-
porarily is recommended in preventing
dirty air from entering the vehicle interior
and helping to cool the vehicle when the
outside air temperature is high.
●Outside/recirculated air mode may auto-
matically switch depending on the tem-
perature setting or the inside
temperature.
■Registering air conditioning settings to
electronic keys (vehicles with driving
position memory)
●Unlocking the vehicle using an electronic
key and turning the engine switch to
IGNITION ON mode will recall that
key’s registered air conditioning settings.
●When the engine switch is turned off, the
current air conditioning settings will auto-
matically be registered to the electronic
key that was used to unlock the vehicle.
●The system may not operate correctly if
more than one electr onic key is in the
vicinity or if the smart access system with
push-button start is used to unlock a pas-

2565-2. Using the air conditioning system and defogger
senger door.
●The doors that can recall the air condi-
tioning setting when unlocked using the
smart access system with push-button
start can be changed.
* For details, con-
tact your Lexus dealer.
*: The doors that can recall the driving
position memory are changed at the
same time.
■Operation of the air conditioning sys-
tem in Eco drive mode
In Eco drive mode, the air conditioning sys-
tem is controlled as follows to prioritize fuel
efficiency:
●Engine speed and compressor operation
controlled to restri ct heating/cooling
capacity
●Fan speed restricted when automatic
mode is selected
To improve air condit ioning performance,
perform the following operations:
●Adjust the fan speed
●Turn off Eco drive mode ( P.236)
■When the outside temperature falls to
nearly 32°F (0°C)
The dehumidification function may not
operate even when A/C is pressed or
“A/C” is selected.
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning
system to the outside air mode.
●During use, various odors from inside and
outside the vehicle may enter into and
accumulate in the air conditioning sys-
tem. This may then cause odor to be
emitted from the vents.
●To reduce potential odors from occur-
ring:
• It is recommended that the air condition- ing system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time imme-
diately after the air conditioning system is
started in automatic mode or with the
micro dust and pollen filter on.
