CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
When the vehicle is stopped
Do not depress the accelerator pedal unnecessarily.
If the shift lever is any position other than P or N, the vehicle may accelerate
suddenly and unexpectedly, causing an accident.
In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while stopped with the “READY” indicator on,
and apply the parking brake as necessary.
If the vehicle is stopped on an incline, in order to prevent accidents caused by
the vehicle rolling forward or backward, always depress the brake pedal and
securely apply the parking brake as needed.
Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause the
exhaust system to overheat, which could result in a fire if combustible mate-
rial is nearby.
When the vehicle is parked
Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the
vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic
material of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior
of the vehicle, and may also cause a short circuit in the vehicle’s electrical
components.
Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a place
such as the glove box or on the floor, it may be lit accidentally when luggage
is loaded or the seat is adjusted, causing a fire.
Do not attach adhesive discs to the windshield or windows. Do not place con-
tainers such as air fresheners on the instrument panel or dashboard. Adhesive
discs or containers may act as lenses, causing a fire in the vehicle.
Do not leave a door or window open if the curved glass is coated with a met-
allized film such as a silver-colored one. Reflected sunlight may cause the
glass to act as a lens, causing a fire.
Always apply the parking brake, shift the shift lever to P, stop the hybrid sys-
tem and lock the vehicle.
Do not leave the vehicle unattended while the hybrid system is operating.
Do not touch the exhaust pipes while the hybrid system is operating or imme-
diately after turning the hybrid system off.
Doing so may cause burns.

braking control, but the power assist to these systems will be lost. This will
make it more difficult to steer and brake, so you should pull over and stop the
vehicle as soon as it is safe to do so.
NOTICE
To prevent 12-volt battery discharge
Do not leave the power switch in ACCESSORY or ON mode for long periods
of time without the hybrid system on.

hybrid system is not operating, the power switch is not off. Exit the vehicle
after turning the power switch off.
Do not stop the hybrid system when the shift lever is in a position other than
P. If the hybrid system is stopped in another shift lever position, the power
switch will not be turned off but instead be turned to ACCESSORY mode. If
the vehicle is left in ACCESSORY mode, 12-volt battery discharge may
occur.
When starting the hybrid system
Do not depress the accelerator pedal unnecessarily.
If the hybrid system becomes difficult to start, have your vehicle checked by
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional immediately.

Interior features
IS300h_EE(OM53B95E)
Registering air conditioning settings to electronic keys (vehicles with driving
position memory)
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
automatically 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 entry & start system is used to unlock a passenger door.
The doors that can recall the air conditioning setting when unlocked using the
smart entry & start system can be changed.* For details, contact any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
*: The doors that can recall the driving position memory are changed at the same
time.
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
immediately after is pressed or “AUTO” is selected.
Fogging up of the windows
The windows will easily fog up when the humidity in the vehicle is high. Turning
(“A/C”) on will dehumidify the air from the outlets and defog the wind-
shield 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.
Outside/recirculated air mode
When driving on dusty roads such as tunnels or in heavy traffic, set the outside/
recirculated air mode button to the recirculated air mode. This is effective in
preventing outside air from entering the vehicle interior. During cooling opera-
tion, setting the recirculated air mode will also cool the vehicle interior effec-
tively.
Outside/recirculated air mode may automatically switch depending on the tem-
perature setting or the inside temperature.
Operation of the air conditioning system in Eco drive mode
In Eco drive mode, the air conditioning system is controlled as follows to priori-
tize fuel efficiency:
Engine speed and compressor operation controlled to restrict heating/cooling
capacity
Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
Adjust the fan speed
Turn off Eco drive mode
