QIf the high coolant temperature
warning light comes on,
flashes or “Engine Coolant
Temp High Stop in a Safe
Place See Owner’s Manual” is
shown on the multi-informa-
tion display
1 Stop the vehicle in a safe place
and turn off the air conditioning
system, and then stop the hybrid
system.
2 If you see steam:
Carefully lift the hood after the
steam subsides.
If you do not see steam:
Carefully lift the hood.
NOTICE
QWhen handling jumper cables
When connecting the jumper cables,
ensure that they do not become entangled in the cooling fan, etc.
QTo prevent damaging the vehicle
The exclusive jump starting terminal is to be used when charging the 12-
volt battery from another vehicle in an emergency. It cannot be used to jump start another vehicle.
If your vehicle overheats
The following may indicate that
your vehicle is overheating.
 The high coolant temperature
warning light ( P.168) comes
on or flashes, or a loss of
hybrid system power is experi-
enced. (For example, the vehi-
cle speed does not increase.)
 “Engine Coolant Temp High
Stop in a Safe Place See
Owner’s Manual” or “Hybrid
System Overheated Output

Correction procedures

5528-2. Steps to take in an emergency
3After the hybrid system has
cooled down sufficiently, inspect
the hoses and radiator core
(radiator) for any leaks.
Radiator
Cooling fan
If a large amount of coolant leaks, immediately contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
4 The coolant level is satisfactory
if it is between the “FULL” and
“LOW” lines on the reservoir.
Reservoir
“FULL” line
“LOW” line
5 Add coolant if necessary.
Water can be used in an emergency if
engine coolant is unavailable. If water was added in an emergency,
have the vehicle inspected at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer as soon as possible.
6 Start the hybrid system and turn
the air conditioning system on to
check that the radiator cooling
fan operates and to check for
coolant leaks from the radiator
or hoses.
The fan operates when the air condi- tioning system is turned on immediately
after a cold start. Confirm that the fan is operating by checking the fan sound and air flow. If it is difficult to check
these, adjust the temperature control switch to “LO” and turn the “A/C” switch ON and OFF. After this, turn the air
conditioning system on and off repeat- edly. (The fan may not operate in freez-ing temperatures.)
7 If the fan is not operating:
Stop the hybrid system immedi-
ately and contact any authorized
Toyota retailer or Toyota autho-
rized repairer, or any reliable
repairer.
If the fan is operating:
Have the vehicle inspected at
the nearest authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.

If the message does not disappear:
Stop the hybrid system and contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer. If the message is not displayed: The hybrid system temperature has
dropped and the vehicle may be driven normally. However, if the message appears again
frequently, contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
WARNING
QWhen inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
OIf 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.
OAfter the hybrid system has been
turned off, check that the “READY” indicator is off.When the hybrid system is operat-
ing, the gasoline engine may auto- matically 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, result-ing in serious injury.
ODo not loosen the coolant reservoir cap while the hybrid system and
radiator are hot. High temperature steam or coolant could spray out.
NOTICE
QWhen adding engine/power con-trol 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 dam- age to the hybrid system.
QTo prevent damage to the cool-ing system
Observe the following precautions:
OAvoid contaminating the coolant with foreign matter (such as sand or dust, etc.).
ODo not use any coolant additive.

QOil capacity (Drain and refill  reference*)
*: The engine oil capacity is a reference quantity to be used when changing the
engine oil. Warm up the engine and turn off the hybrid system, wait more than 5
minutes, and check the oil level on the dipstick.
QEngine oil selection
“Toyota Genuine Motor Oil” is used
in your Toyota vehicle. Toyota rec-
ommends the use of approved
“Toyota Genuine Motor Oil”.
Another motor oil of matching qual-
ity can also be used.
Oil grade:
0W-16:
API grade SN “Resource-Conserv-
ing”, SN PLUS “Resource-Conserv-
ing” or SP “Resource-Conserving”;
or ILSAC GF-6B multigrade engine
oil
0W-20 and 5W-30:
API grade SM “Energy-Conserv-
ing”, 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 manufacturing,
and the best choice for good fuel
economy and good starting in cold
weather.
If SAE 0W-16 oil is not available,
SAE 0W-20 oil may be used. How-
ever, it should be replaced with
SAE 0W-16 at the next oil change.

5629-1. Specifications
Temperature range anticipated
before next oil change
Preferred
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 tempera-
ture. An oil with a higher viscos-
ity (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 oil you should use.
API Service Symbol
Top portion: “API SERVICE SP” means
the oil quality designation by American
Petroleum Institute (API).
Center portion: “SAE 0W-16” means
the SAE viscosity grade.
Lower portion: “Resource-Conserving”
means that the oil has fuel-saving and
environmental protection capabilities.
ILSAC Certification Mark
The International Lubricant Specifica-
tion Advisory Committee (ILSAC) Certi-
fication Mark is displayed on the front of
the container.

QUse of ethanol blended gasoline in a gasoline engine
Toyota allows the use of ethanol
blended gasoline where the ethanol
content is up to 10%. Make sure that the
ethanol blended gasoline to be used has
a Research Octane Number that follows
the above.
QIf your engine knocks
OConsult any authorized Toyota retailer
or Toyota authorized repairer, or any
reliable repairer.
OYou may occasionally notice light knocking for a short time while accel-
erating or driving uphill. This is normal and there is no need for concern.
Fuel information
When you find these types of
fuel label at the gas station,
use only the fuel with one of
the following labels.
EU area:
You must only use unleaded
gasoline conforming to Euro-
pean standard EN228.
Select unleaded gasoline with
a Research Octane Number of
95 or higher for optimum
engine performance.
Except EU area:
You must only use unleaded
gasoline.
Select unleaded gasoline with
a Research Octane Number of
91 or higher for optimum
engine performance.
NOTICE
QNotice on fuel quality
ODo not use improper fuels. If improper fuels are used, the engine will be damaged.
ODo not use gasoline with metallic additives, for example manganese,
iron or lead, otherwise it may cause damage on your engine or emission control system.
ODo not add aftermarket fuel addi-tives which contain metallic addi-
tives.
OEU 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
retailer or Toyota authorized repairer, or any reliable repairer.
OExcept 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 gaso-line 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 spec-ification and quality can be guaran-
teed. In case of any doubt, ask any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
