2012 TOYOTA AURIS engine coolant

6887-2. Steps to take in an emergency
UK_AURIS/AURIS_HV_EE (OM12E33E)
After the hybrid system has
cooled down sufficiently,
check the engine coolant
level and inspect the cooling
system for leaks.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is
unavailable. (P. 709)
Have the vehicle inspected at the nearest authorized Toyota dealer
or repairer, or another duly qualified and equipped professional as
soon as possible.
If “Hybrid System Overheat” is shown on the multi-information
display
Stop the vehicle in a safe place and turn off the air conditioning
system.
Leave the hybrid system operating and carefully lift the hood.

Overheating
If you observe the following, your vehicle may be overheating:
The high engine coolant temperature is shown on the multi-information dis-
play or a loss of power is experienced.
“Hybrid System Overheat” is shown on the multi-information display.
Steam comes out from under the hood.
CAUTION
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.
Keep hands and clothing away from the fans, etc. while the hybrid system
is operating.
For vehicles with a hybrid system, there are times when the gasoline
engine automatically starts to run or the cooling fans suddenly start to
operate. Do not touch or approach the rotating parts of the belt or fans.
Doing so may lead to fingers, clothes or tools getting caught, resulting in
injury.
Do not loosen the coolant reservoir caps while the hybrid system and radi-
ator are hot.
High temperature steam or coolant could spray out.
NOTICE
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 commercially available coolant additives.
