IS300h_EE(OM53D89E)
■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 accu-
mulate in the air conditioning system. This may then cause odor to be emitted from the
vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode prior
to turning the vehicle off. • The start timing of the blower may be dela yed for a short period of time immediately
after the air conditioning system is started in automatic mode.
■Air conditioning filter

■Customization
Settings (e.g. A/C Auto switch operation) can be changed. (Customizable features: P. 663)
WARNING
■To prevent the windshield from fogging up
●Do not use during cool air operation in extremely humid weather. The differ- ence 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.
■To prevent burns
●Do not touch the rear view mirror surfaces when the outside rear view mirror defog-
gers are on.
●Do not touch the glass at lower part of the windshield or to the side of the front pillars
when the windshield wiper de-icer is on.
NOTICE
■To prevent 12-vol t battery discharge
Do not leave the air conditioni ng system on longer than necessary when the hybrid sys- tem is off.
●Do not place anything on the instrumentpanel which may cover th e air outlets. Other-
wise, air flow may be obstructed, preventing
the windshield defoggers from defogging.

WARNING
The engine compartment contains many mechanisms and fluids that may move suddenly, become hot, or become electrically energize d. To avoid death or serious injury, observe
the following precautions.
■When working on the engine compartment
●Make sure that the “ACCESSORY” or “I GNITION ON” on the multi-information
display and the “READY” indicator are both off.
●Keep hands, clothing and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, power control unit, radiator, exhaust manifold, etc.
right after driving as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes are flamma-
ble.
●Take care because brake fluid can harm yo ur hands or eyes and damage painted sur-
faces. If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately. If you still experience disc omfort, consult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the power switch is off. With the power switch in ON mode, the elec tric cooling fans may automatically start to
run if the air conditioning is on and/ or the coolant temperature is high. (P. 521)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting in
your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner f ilter removed may cause excessive engine wear due to dirt
in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or when
the fluid level in the accumulator is high. If the reservoir needs freq uent refilling, it may indicate a serious problem.
