PRIUS PHV_OM_OM47A89E_(EE)
NOTICE
■Hybrid battery (traction battery) air vents
● Make sure not to block the air intake vent with anything, such as a seat
cover, plastic cover, or luggage. The hybrid battery (traction battery) may
overheat and be damaged.
● When dust etc. has accumulated in the air intake vent, clean it with a vac-
uum cleaner to prevent the vent from clogging.
● Do not wet or allow foreign substances to enter the air vents as this may
cause a short circuit and damage the hybrid battery (traction battery).
● Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the battery
may be damaged. Have the vehicle inspected by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
● A filter is installed to the air intake vent. When the filter remains noticeably
dirty even after cleaning the air intake vent, filter cleaning or replacement
is recommended. When cleaning the filter, refer to P. 552.
■ Notice about fuel
● For plug-in hybrid vehicles, fuel may remain in the tank for a long time and
undergo changes in quality depending on the how the vehicle is used.
Refuel at least 20 L (5.3 gal., 4.4 Imp.gal.) of fuel every 12 months (refuel
a total of at least 20 L [5.3 gal., 4.4 Imp.gal.] over a 12-month period), as
this may affect components of the fuel system or the gasoline engine.
● If the vehicle has not been refueled for a certain amount of time and it is
possible that the quality of the fuel remaining in the tank has changed, “No
new fuel has been added recently. Please refuel” is displayed on the multi-
information display when the power switch is turned to ON mode. If the
message is displayed, refuel the vehicle immediately.
5146-1. Using the air conditioning system and defogger
PRIUS PHV_OM_OM47A89E_(EE)
■ Ventilation and air conditioning odors
● To let the 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 system. This may then cause odor to
be emitted from the vents.
● In order to suppress odors that occur when the air conditioning system
starts, fresh air is automatically taken in when parked.
● To reduce potential odors from occurring, the start timing of the blower may
be delayed for a short period of time immediately after the air conditioning
system is started in automatic mode.
■ Air conditioning filter
P. 609
■ Customization
Settings (e.g. A/C auto switching operation) can be changed.
(Customizable features: P. 708)
WARNING
■To prevent the windshield from fogging up
● Do not use 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, block-
ing your vision.
■ To prevent burns
Do not touch the rear view mirror surfaces when the outside rear view mirror
defoggers are on.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.

■Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year to
maintain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge
or brush to apply the foam. Rub in overlapping circles. Do not use water.
Wipe dirty surfaces and let them dry. Excellent results are obtained by keep-

■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
■Cleaning the air intake vents and filters
●Dust on the air intake vents or filters may interferes cooling of the hybrid bat-
tery (traction battery) and results in poor electricity and fuel consumption.
Clean the air intake vents and filters periodically.
●If continuing to drive the vehicle with “Maintenance required for Traction bat-
tery cooling parts See owner’s manual” shown on the multi-information dis-
play, the hybrid battery (traction battery) may overheat, leading to
decreasing in distance that can be driven using the electric motor. It may
cause poor electricity and fuel consumption or a malfunction. If the warning
message is shown, clean the air intake vents and filters immediately.
●Improper handling may result in damage to the grille or filters. If you have

■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.

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 frequent refilling, it may indicate a serious problem.
