5548-2. Steps to take in an emergency
again and check the multi-infor-
mation display.
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.
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.
