When trouble arises
Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the 12-volt 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 connected.
Close the exclusive jump starting terminal cover, and reinstall 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.
■Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■ To prevent 12-volt battery discharge
●Turn off the headlights and the audio system while the hybrid system is off.
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■ When the 12-volt battery is removed or discharged
●The hybrid system may not start. ( →P. 328)
● If the 12-volt battery discharges while the shift position is in P, it may not be
possible to shift the shift position to other positions. In this case, the vehicle
cannot be towed without lifting both front wheels because the front wheels
will be locked. ( →P. 370)
● When the 12-volt battery is reconnected, start the hybrid system and con-
firm that the shift position can be changed to each position using the shift
position indicator.
● Make sure that the key is not inside the vehicle when recharging or replac-
ing the 12-volt battery. The key may be locked in the vehicle if the alarm is
activated. ( →P. 97)

When trouble arises
After stopping the hybrid system and waiting for 5 minutes or
more, start the hybrid system and check for the instrument clus-
ter or multi-information display.
If the hybrid system overheat warning light does not turn off or
the message does not disappear:
Stop the hybrid system and contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
If the hybrid system overheat warning light does not come on or
the message is not displayed:
The hybrid system temperature has dropped and the vehicle may
be driven normally.
However, if the warning light comes on again frequently or the message
appears again frequently, contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
WARNING
■ When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
●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.
● After the hybrid system has been turned off, check that the indicator on the
power switch and the “READY” indicator are off.
When the hybrid system is operating, the gasoline engine may automati-
cally start, or the cooling fan may suddenly operate even if the gasoline
engine stops. Do not touch or approach rotating parts such as the fan,
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.
High temperature steam or coolant could spray out.

■
When adding engine/power control unit coolant
Add coolant slowly after the hybrid system has cooled down sufficiently.
Adding cool coolant to a hot hybrid system 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 additive.

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-20, 5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving” or SN
“Resource-Conserving”; or ILSAC multigrade engine oil
15W-40:
API grade SL, SM or SN multigrade engine oil
Recommended viscosity (SAE):
SAE 0W-20 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-20 oil is not avail-
able, 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 0W-20 or 5W-
30 engine oil is recommended.

Vehicle specifications
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 contain-
ers to help you select the oil you should use.
API Service Symbol
Top portion: “API SERVICE SN”
means the oil quality designa-
tion by American Petroleum
Institute (API).
Center portion: “SAE 0W-20”
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.

Fuel infor mation
XEU area
Your vehicle must use only unleaded gasoline conforming to
European standard EN228.
For optimum engine performance, select unleaded gasoline with a
Research Octane Number of 95 or higher.
XExcept 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.
■ 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 qualified
and equipped professional.
● You may occasionally notice light knocking for a short time while accelerat-
ing or driving uphill. This is normal and there is no need for concern.
You must only use unleaded gasoline.
For optimum engine performance, select unleaded gasoline with
a Research Octane Number of 95 or higher.

Notice on fuel quality
●Do not use improper fuels. If improper fuels are used the engine will be
damaged.
● Do not use leaded gasoline.
Leaded gasoline will cause the three-way catalytic converter to lose its
effectiveness and emission control system to function improperly.
● Gasoline engine (EU area): Bioethanol fuel sold under names such as
“E50” or “E85” and fuel containing a large amount of ethanol should not be
used. The use of these fuels will damage the vehicle’s fuel system. In case
of any doubt, ask any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional.
● Gasoline engine (except EU area): Bioethanol fuel sold under names such
as “E50” or “E85” and fuel containing a large amount of ethanol should not
be used. Your vehicle can use gasoline mixed with 10% max ethanol. The
use of fuel with more than 10% ethanol content (E10) will damage the
vehicle’s fuel system. You must ensure that refueling is carried out only
from a source where fuel specification and quality can be guaranteed. In
case of any doubt, ask any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional.
