8-2. Steps to take in an emergency
When trouble arises
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.
■ 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 “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.
● Do not loosen the coolant reservoir
cap while the hybrid system and
radiator are hot.
High temperature steam or coolant
could spray out.
■ When 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.
■ To prevent damage to the cool-
ing system
Observe the following precautions:
● Avoid contaminating the coolant
with foreign matter (such as sand or
dust, etc.).
● Do not use any coolant additive.
