When trouble arises
YARIS_F (including HV)_WE_52D27EStart the hybrid system and check for the hybrid system over-
heat warning light.
If the warning light does not go off:
Stop the hybrid system and contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped
professional.
If the warning light goes off:
Have the vehicle inspected at the nearest authorized Toy-
ota dealer or repairer, or another duly qualified and
equipped professional.
CAUTION
To prevent an accident or injury when inspecting under the hood of
your vehicle
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, caus-
ing serious injuries such as burns.
Check that the “READY” indicator is off.
On hybrid vehicles, the gasoline engine may automatically 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 fin-
gers 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.
Serious injuries, such as burns, may result from hot coolant and steam
released under pressure.

Fuel tank opening for unleaded gasoline (gasoline engine)
To help prevent incorrect fueling, your vehicle has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
If you plan to drive in foreign countries (diesel engine)
Low sulfur diesel fuel may not be available, so please check the availability
with your distributor.
If your engine knocks
Consult any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional.
You may occasionally notice light knocking for a short time while acceler-
ating or driving uphill. This is normal and there is no need for concern.
NOTICE
Notice on fuel quality (gasoline engine)
Do not use improper fuels. If improper fuels are used, the engine will be
damaged.
Do not use leaded gasoline.
Leaded gasoline will cause the three-way catalytic converter to lose its
effectiveness and the emission control system to function improperly.
EU 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 dealer or repairer, or another duly qualified and
equipped professional.
Except 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 gasoline 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 specification and quality can be guaranteed. In case of any
doubt, ask any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional.
