Weight limits
Check the allowable towing capacity, GVM (Gross Vehicle Mass),
MPAC (Maximum Permissible Axle Capacity), and permissible draw
bar load before towing. (P. 562)
Towing hitch/bracket
Lexus recommends the use of the Lexus hitch/bracket for your vehicle.
Other products of a suitable nature and comparable quality may also be
used.
To prevent an accident
The handling of the vehicle will feel different when towing a trailer.
Beware of the 3 most common causes of towing-related accidents:
driver error, excessive speed, and overloading.
Trailer towing (vehicles with a towing package)
The strain of towing a trailer will have a negative impact on the running
performance, handling, fuel consumption and endurance of your vehicle.
Use the vehicle features in the correct manner and operate the vehicle
with care for safer driving and optimal comfort. Damage and/or malfunc-
tions that occur as a result of towing performed for commercial purposes
are not covered by the Lexus warranty.
Ask your local authorized Lexus dealer or repairer, or another duly qual-
ified and equipped professional for further details before towing, as there
are additional legal requirements in some countries.

Close all the doors and windows, and turn the power switch off.
Confirm the type of fuel.
Fuel types
EU area:
Unleaded gasoline conforming to European standard EN228, Research Octane
Number of 95 or higher
Except EU area:
Unleaded gasoline, Research Octane Number of 95 or higher
Use of ethanol blended gasoline in a gasoline engine
Lexus allows the use of ethanol blended gasoline where the ethanol content is up
to 10%. Make sure that the ethanol blended gasoline to be used has a Research
Octane Number that follows the above.
Opening the fuel tank cap
Perform the following steps to open the fuel tank cap:
Before refueling the vehicle

2424-4. Refueling
IS300h_EE(OM53B95E)
CAUTION
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 refueling because sparks resulting from static electric-
ity 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 discharged 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 vehicle.
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 nozzle 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.

IS300h_EE(OM53B95E)
After refueling, turn the fuel tank
cap until you hear a click. Once
the cap is released, it will turn
slightly in the opposite direction.
Close the fuel filler door, and
press the center of the rear edge
of the fuel filler door until you
hear a click.
When you lock the doors, the fuel
filler door will also lock.
Fuel filler door lock condition
The fuel filler door may not be locked even when the vehicle’s doors are locked
in the following situations:
When operating the door lock button inside the vehicle
When the automatic door locking system is operated (P. 140)
When the fuel filler door is closed after the vehicle’s doors are locked

serious injury.

4076-1. Using the air conditioning system
6
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

4667-3. Do-it-yourself maintenance
IS300h_EE(OM53B95E)
Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
Reduced fuel efficiency
Reduced driving comfort and tire life
Reduced safety
Damage to the drivetrain
If a tire needs frequent inflating, have it checked by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional.
Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been driven for
more than 1.5 km or 1 mile, you will get an accurate cold tire inflation pressure
reading.
Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation pressure
that is even just a few pounds off can affect ride quality and handling.
Do not reduce tire inflation pressure after driving. It is normal for tire inflation
pressure to be higher after driving.
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is balanced.
Tire inflation pressure
Make sure to maintain proper tire inflation pressure. Tire inflation pres-
sure should be checked at least once per month. However, Lexus recom-
mends that tire inflation pressure be checked once every two weeks.
