Overheating
The following symptoms may occur when your vehicle is overheating:
Hybrid system output decreases.
Steam comes out from the engine area.
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.
For vehicles with a hybrid system, there are times when the gasoline
engine automatically starts to run or the cooling fan suddenly start to oper-
ate. Do not touch or approach the rotating parts of the belt or fan. Doing so
may lead to fingers, clothes or tools getting caught, resulting in 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.
