Toyota Yaris: Fuel and Engine Exhaust Precautions / Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use ONLY
UNLEADED FUEL, which will reduce exhaust emissions and keep
spark plug fouling to a minimum.
To achieve maximum engine performance, use the specified fuel.

* 1: U.S. federal law requires that octane ratings be posted
on gas station
pumps.
Fuel with a rating lower than 87 octane (91 RON) could cause the
emission control system to lose effectiveness. It could also cause
engine knocking and serious engine damage.
Gasoline blended with oxygenates such as alcohol or ether compounds are
generally referred to as oxygenated fuels. The common
gasoline blend that can be used with your vehicle is ethanol blended
at no more than 10 %. Gasoline containing alcohol, such as ethanol or
methanol, may be marketed under the name “Gasohol”.
Vehicle damage and drivability problems resulting from the use of the
following may not be covered by the warranty.
- Gasohol containing more than 10 % ethanol.
- Gasoline or gasohol containing methanol.
- Leaded fuel or leaded gasohol.
NOTICE
This vehicle is equipped with an emission control system (the catalytic
converter is part of this system) that enables the vehicle to comply
with existing exhaust emissions requirements...
Other information:
DESCRIPTION The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition. These DTCs are stored when the skid control ECU (brake actuator assembly) receives an internal malfunction signal from the yaw rate and acceleration sensor (airbag sensor assembly)...
DESCRIPTION If none of the switch indicators on the air conditioning control assembly illuminate, the following factors may be the cause. Symptom Factor A/C switch indicator does not illuminate
Vehicle control history (RoB)
Air conditioning amplifier assembly malfunction
Air conditioning control assembly malfunction
A/C switch malfunction
A/C switch indicator malfunction (including when indicator turned off without switch operation)
Servo motor initialization (incomplete)
Mechanical locking of damper and damper link
Refrigerant pressure is extremely low
Low detected ambient temperature (including thermistor assembly malfunction)
