PRIUS +_OM_OM47821E_(EE)
Start the engine of the second vehicle. Increase the engine
speed slightly and maintain at that level for approximately
5 minutes to recharge the battery of your vehicle.
Maintain the engine speed of the second vehicle and start
the hybrid system of your vehicle by turning the “POWER”
switch to ON mode.
Make sure the “READY” indicator comes on. If the indicator
light does not come on, contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped
professional.
Once the hybrid system has started, remove the jumper
cables in the exact reverse order from which they were con-
nected.
Close the exclusive jump starting terminal cover, and rein-
stall the fuse box cover to its original position.
When installing, first hook the fuse box cover onto the two rear
tabs.
Once the hybrid system starts, have the vehicle inspected at any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional as soon as possible.

CAUTION
To prevent an accident or injury when inspecting under the hood of
your vehicle
If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot, caus-
ing serious injuries such as burns.
Check that the indicator on the “POWER” switch and the “READY” indica-
tor are off.
On hybrid vehicles, the gasoline engine may automatically start, or the
cooling fans may suddenly operate even if the gasoline engine stops. Do
not touch or approach rotating parts such as the fans, which may lead to
fingers or clothing (especially a tie, a scarf or a muffler) getting caught,
resulting in serious injury.
Do not loosen the coolant reservoir cap while the hybrid system and radia-
tor are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
NOTICE
When adding engine/power control unit coolant
Wait until the hybrid system has cooled down before adding engine/power
control unit coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot hybrid sys-
tem too quickly can cause damage to the hybrid system.
To prevent damage to the cooling system
Observe the following precautions:
Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.)
Do not use any coolant additives other than the Toyota genuine or similar
coolant additives

PRIUS +_OM_OM47821E_(EE)Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy
the following grade and viscosity.
Oil grade:
0W-20, 5W-20, 5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving”, SN
“Resource-Conserving” or ILSAC multigrade engine oil
15W-40 and 20W-50:
API grade SL, SM or SN multigrade engine oil

Vehicle specifications
PRIUS +_OM_OM47821E_(EE)Recommended viscosity (SAE):
SAE 0W-20 is filled into your
Toyota vehicle at manufacturing,
and the best choice for good fuel
economy, and good starting in
cold weather.
If SAE 0W-20 oil is not available,
SAE 5W-30 oil may be used.
However, it should be replaced
with SAE 0W-20 at the next oil
change.
If you use SAE 10W-30 or a
higher viscosity engine oil in
extremely low temperatures, the
engine may become difficult to
start, so SAE 5W-30 or lower vis-
cosity engine oil is recom-
mended.
Temperature range anticipated before
next oil change.

PRIUS +_OM_OM47821E_(EE)
Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 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 20 in 0W-20 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 containers
to help you select the proper oil you should use.
API Service Symbol
Top portion: The oil quality desig-
nation by API (American Petro-
leum Institute) (SN)
Center portion: The SAE viscosity
grade (SAE 0W-20)
Lower portion:
“Resource-conserving” means
that the oil has fuel saving and
environmental protection capabili-
ties.
ILSAC Certification Mark
The ILSAC (International Lubri-
cant Standardization and
Approval Committee) certification
Mark is displayed on the front of
the container.

Fuel infor mation
Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Toyota has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
If your engine knocks
Consult any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional.
You may occasionally notice light knocking for a short time while acceler-
ating or driving uphill. This is normal and there is no need for concern.
Except EU area:
Your vehicle must use only unleaded gasoline.
For optimum engine performance, select unleaded gasoline with a
Research Octane Number of 95 or higher.
EU area:
Your vehicle must use only unleaded gasoline conforming to Euro-
pean standard EN228.
For optimum engine performance, select unleaded gasoline with a
Research Octane Number of 95 or higher.
