5366-1. Using the air conditioning system and defogger
Prius Plug-in Hybrid_OM_OM47F38E_(EE)
■Operating conditions
The system will only operate if all of the following conditions are met:
●The shift position is in P.
●The power switch is off.
*
●All doors are closed.
●The hood is closed.
*: The Remote Air Conditioning System cannot be used for approximately 3
minutes and a half after the power switch is turned off.
■Remote Air Conditioning System automatic shut-off
The system will automatically shut off under the following conditions:
●About 10 minutes have passed since operation began
●Any one of the operating conditions is not met
The system may also shut off if the charge level of the hybrid battery (traction
battery) drops to low.
■Conditions affecting operation
The system may not start in the following situations:
●The charge level of the hybrid battery (traction battery) is low
●The outside temperature is extremely low
●When the hybrid system is cool (for example, after being left for a long time
in low temperatures)
■Windshield defogger
When defogging the windshield using the Remote Air Conditioning System,
defogging may be insufficient due to the power being restricted more than
during normal air conditioning operation. Also, the outside of the windshield
may fog up due to the outside temperature, humidity or air conditioning set
temperature.
■Using the heater via the Remote Air Conditioning System
When the outside heat exchanger becomes frosted over, heating perfor-
mance may decline due to automatically switching to the frost removal opera-
tion.
■Security feature
Any unlocked doors will be automatically locked when the system is operat-
ing. The emergency flashers flash to indicate that the doors have been locked
or the system has been turned off.
(The doors locked: Once; The system turned off: Twice)

Maintenance and care
■Note for a smart entry & start system
If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. In that case, follow the fol-
lowing correction procedures to wash the vehicle:
●Place the key in a position 2 m (6 ft.) or more separate from the vehicle
while the vehicle is being washed. (Take care to ensure that the key is not
stolen.)
●Set the electronic key to battery-saving mode to disable the smart entry &
start system. (P. 285)
■Wheels and wheel ornaments
●Remove any dirt immediately by using a neutral detergent.
●Wash detergent off with water immediately after use.
●To protect the paint from damage, make sure to observe the following pre-
cautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such as after driv-
ing or parking in hot weather
■Brake pads and calipers
Rust may form if the vehicle is parked with wet brake pads or disc rotors,
causing them to stick. Before parking the vehicle after it is washed, drive
slowly and apply the brakes several times to dry the parts.
■Bumpers
Do not scrub with abrasive cleaners.
■Front side windows water-repellent coating
The following precautions can extend the effectiveness of the water-repellent
coating.
●Remove any dirt, etc. from the front side windows regularly.
●Do not allow dirt and dust to accumulate on the windows for a long period.
Clean the windows with a soft, damp cloth as soon as possible.
●Do not use wax or glass cleaners that contain abrasives when cleaning the
windows.
●Do not use any metallic objects to remove condensation build up.
■Plated portions
If dirt cannot be removed, clean the parts as follows:
●Use a soft cloth dampened with an approximately 5% solution of neutral
detergent and water to clean the dirt off.
●Wipe the surface with a dry, soft cloth to remove any remaining moisture.
●To remove oily deposits, use alcohol wet wipes or a similar product.

Maintenance and care
WARNING
■Pre-driving check
Check that the hood is fully closed and locked.
If the hood is not locked properly, it may open while the vehicle is in motion
and cause an accident, which may result in death or serious injury.
■ To prevent burns
■ After installing the support rod into the slot
Make sure the rod supports the hood securely from falling down on to your
head or body.
■ When closing the hood
NOTICE
■When closing the hood
Be sure to return the supporting rod to its clip before closing the hood. Clos-
ing the hood without returning the support rod properly could cause the
hood to bend.
Do not touch the air conditioning pipes
when the air conditioning compressor is
operating or after it is stopped, because
the air conditioning pipes are hot.
Touching by hands before the air condi-
tioning pipes cool down may cause
burns.
When closing the hood, take extra care
to prevent your fingers etc. from being
caught.

Maintenance and care
■Adding engine oil
If the oil level is below or near
the low level mark, add engine
oil of the same type as that
already in the engine.
Make sure to check the oil type and prepare the items needed
before adding oil.
Remove the oil filler cap by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.
Install the oil filler cap by turning it clockwise.
■ Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the following
situations, oil consumption may increase, and engine oil may need to be
refilled in between oil maintenance intervals.
● When the engine is new, for example directly after purchasing the vehicle or
after replacing the engine
● If low quality oil or oil of an inappropriate viscosity is used
● When driving at high engine speeds or with a heavy load, or when driving
while accelerating or decelerating frequently
● When leaving the engine idling for a long time, or when driving frequently
through heavy traffic

Maintenance and care
■When opening the cover of the positive (+) battery terminal
■ Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, obser ve the following precautions before
recharging:
● If recharging with the 12-volt battery installed on the vehicle, be sure to dis-
connect the ground cable.
● Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the 12-volt battery.
■ After recharging/reconnecting the 12-volt battery
● Unlocking the doors using the smart entry & start system may not be possi-
ble immediately after reconnecting the 12-volt battery. If this happens, use
the wireless remote control or the mechanical key to lock/unlock the doors.
● Start the hybrid system with the power switch in ACCESSORY mode. The
hybrid system may not start with the power switch turned off. However, the
hybrid system will operate normally from the second attempt.
● The power switch mode is recorded by the vehicle. If the 12-volt battery is
reconnected, the vehicle will return the power switch mode to the status it
was in before the 12-volt battery was disconnected. Make sure to turn off
the power switch before disconnect the 12-volt battery. Take extra care
when connecting the 12-volt battery if the power switch mode prior to dis-
charge is unknown.
If the system will not start even after multiple attempts at all methods above,
contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer.
While pushing the portion shown in the
illustration from both sides, lift the end of
the cover up.
