NOTICE
■Conditions in which the function may not operate correctly
In the following conditions, it may not operate correctly
● The portable device is fully charged
● There is foreign matter between the charge area and portable device
● The temperature of the portable device gets higher from charging
● The charging surface of the portable device is facing up
● The placement of the portable device is out of alignment with the charge
area
● Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that gener ates strong radio waves or electrical
noise
● When the electronic key is in contact with, or is covered by the following
metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
● When other wireless keys (that emit radio waves) are being used nearby
In addition, excluding the above-mentioned, when the charger does not per-
form normally or the operation indicato r light is flashing continuously, it is
considered that the wireless charger is malfunctioning. Contact any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■ To prevent failure or damage to data
● Do not bring magnetic cards, such as credit cards, or magnetic recording
media, etc., close to the charger while charging, otherwise, data may dis-
appear under the influence of magnetism. Also, do not bring precision
instruments such as wrist watches, etc., close to the charger, as such
objects may break.
● Do not leave portable devices in the cabin. The temperature inside the
cabin may become high, when under the sun, and cause damage to the
device.
■ To prevent 12-volt battery discharge
When the hybrid system is stopped, do not use the wireless charger for a
long time.

5827-3. Do-it-yourself maintenance
Prius Plug-in Hybrid_OM_OM47F38E_(EE)
WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become el ectrically energized. To avoid death
or serious injury, observe the following precautions.
■ When working on the engine compartment
● Make sure that the “Accessory”, “Ignition ON” or mileage display (P. 213)
on the main display and the “READY” indicator are both off.
● Keep hands, clothing and tools away from the moving fan.
● 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 flammable.
● Be extremely cautious when working on the 12-volt battery. It contains poi-
sonous and corrosive sulfuric acid.
● Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately. If you still experience discom-
fort, 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 electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. ( P. 593)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.

With the engine at operating temperature and turned off, check the oil
level on the dipstick.
■Checking the engine oil
Park the vehicle on level ground. After warming up the engine
and turning off the hybrid system, wait more than 5 minutes for
the oil to drain back into the bottom of the engine.
Holding a rag under the end,
pull the dipstick out.
Wipe the dipstick clean.
Reinsert the dipstick fully.

■Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Toyota
recommends the use of approved “Toyota Genuine Motor Oil”.
Another motor oil of matching quality can also be used.
Oil grade:
0W-16:
API grade SN “Resource-Conserving”, SN PLUS “Resource-Con-
serving” or SP “Resource-Conserving”; or ILSAC GF-6B multigrade
engine oil
0W-20 and 5W-30:
API grade SM “Energy-Conserving”, SN “Resource-Conserving”,
SN PLUS “Resource-Conserving” or SP “Resource-Conserving”; or
ILSAC GF-6A multigrade engine oil
Recommended viscosity (SAE):
SAE 0W-16 is filled into your
Toyota vehicle at manufactur-
ing, and the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-16 oil is not avail-
able, SAE 0W-20 oil may be
used. However, it should be
replaced with SAE 0W-16 at the
next oil change.

Vehicle specifications
Oil viscosity (0W-16 is explained here as an example):
• The 0W in 0W-16 indicates the characteristic of the oil which
allows cold startability. Oils with a lower value before the W allow
for easier starting of the engine in cold weather.
• The 16 in 0W-16 indicates the viscosity characteristic of the oil
when the oil is at high temperature. An oil with a higher viscosity
(one with a higher value) may be better suited if the vehicle is
operated at high speeds, or under extreme load conditions.
How to read oil container labels:
Either or both API registered marks are added to some oil contain-
ers to help you select the oil you should use.
API Service Symbol
Top portion: “API SERVICE SP”
means the oil quality designa-
tion by American Petroleum Ins-
titute (API).
Center portion: “SAE 0W-16”
means the SAE viscosity grade.
Lower portion: “Resource-
Conserving” means that the oil
has fuel-saving and environ-
mental protection capabilities.
ILSAC Certification Mark
The International Lubricant Specification Advisory Committee (ILSAC)
Certification Mark is displayed on the front of the container.
