If a large amount of coolant
leaks, immediately contact
any authorized Toyota dealer
or repairer, or another duly
qualified and equipped pro-
fessional.
The coolant level is satisfactory if it is between the “F” and “L”
lines on the reservoir.
Reservoir

Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
If water was added in an emer-

ter or multi-information display.

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.

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.

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.

WARNING
■ Cautions during customization
As the hybrid system needs to be operating during customization, ensure
that the vehicle is parked in a place with adequate ventilation. In a closed
area such as a garage, exhaust gases including harmful carbon monoxide
(CO) may collect and enter the vehicle. This may lead to death or a serious
health hazard.
NOTICE
■During customization
To prevent 12-volt battery discharge, ens ure that the hybrid system is oper-
ating while customizing features.
