Stop the vehicle immediately.
A buzzer sounds and a warning message is shown on the multi-infor-
mation display. The following warnings indicate the possibility of dam-
age to the vehicle that may lead to an accident. Immediately stop the
vehicle in a safe place and contact your Toyota dealer.

■While the engine oil level warning is displayed
Continued engine operation with low engine oil will damage the engine.

Star t th e en gine o f the se co nd vehicle. In cre ase th e e ngine
speed slightly and maintain at that level for approximately
5minutes to charge 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 your Toyota dealer.
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
your Toyota dealer as soon as possible.

CAUTION
■To p r e v e n t a n a c c i d e n t o r i n j u r y 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 p r e v e n t d a m a g e t o t h e c o o l i n g s y s t e m
Observe the following precautions:
●Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.)
●Do not use commercially available coolant additives

NOTICE
■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 5.3 gal.(20 L, 4.4 Imp.gal.) of fuel every 6 months (refuel a
total of at least 5.3 gal. [20 L, 4.4 Imp.gal.] over a 6-month period), as this
may affect components of the fuel system or the gasoline engine.

■Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
To y o t a a p p r o v e d “ To y o t a G e n u i n e M o t o r O i l ” o r e q u i v a l e n t t o s a t i s f y
the following grade and viscosity.
Oil grade: ILSAC multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the good choice
for good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.
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.
