■Running out of fuel
When the vehicle has run out of fuel and the
hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to
make the low fuel level warning light
( P.367) go off. If there is only a small
amount of fuel, the hybrid system may not
be able to start. (The standard amount of fuel is about 2.4gal. [9.0 L, 2.0 Imp.gal.],
when the vehicle is on a level surface. This
value may vary when the vehicle is on a
slope. Add extra fuel when the vehicle is
inclined.)
■Electromagnetic waves
●High voltage parts and cables on hybrid
vehicles incorporate electromagnetic
Hybrid system precautions
Take care when handling the hybrid system,
as it is a high voltage system (about
650 V at maximum) as well as contains parts that become extremely hot when
the hybrid system is operating. Obey th e warning labels attached to the vehi-
cle.

2675-3. Using the air conditioning system
5
Interior features
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 regardless of the air con-
ditioning setting depending on the
temperature setting or inside tempera-
ture.
■Registering air conditioning settings to
electronic keys
●Unlocking the vehicle using an electronic
key and turning the power switch to ON
mode will recall that key’s registered air
conditioning settings.
●When the power 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 electronic key is in the
vicinity or if the smart access system with
push-button start is used to unlock the
passenger door.
●Vehicles with the driving position mem-
ory: The doors that can recall the air con-
ditioning setting
* when unlocked using
the smart access system with push-but-
ton start can be changed. For details,
contact your Lexus dealer.
*: The doors that can recall the driving posi-
tion 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 conditioning performance,
perform the following operations:
●Turn off eco air conditioning mode
( P.267)
●Adjust the fan speed
●Turn off Eco drive mode ( P.212)
■When the outside temperature falls to
nearly 32°F (0°C)
The dehumidification function may not
operate even when “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.
●When parking, the system automatically
switches to fresh air intake mode to
encourage better air circulation through-
out the vehicle, helping to reduce odors
that occur when starting the vehicle.
■Using the voice command system
Air conditioning system can be operated
using voice commands. For details, refer to
the “NAVIGATION AND MULTIMEDIA
SYSTEM OWNER’S MANUAL”.
■Air conditioning filter

■Customization
Settings (e.g. A/C Auto switch operation)
can be changed.
(Customizable features P.418)
WARNING
■To prevent the windshield from fog-
ging up
Do not use the windshield defogger
switch during cool air operation in
extremely humid weather. The difference
between the temperature of the outside
air and that of the windshield can cause
the outer surface of the windshield to fog
up, blocking your vision.
