on for long periods with the engine not running could cause the battery
power to be depleted.
● The temperature of the seat warmer cannot be adjusted beyond High, Mid
and Low because the seat warmer is controlled by a thermostat.

Before Driving
The system operates only when the driver is in the vehicle or within
operational range while the key is being carried.
■Starting the Engine Operational range
●Starting the engine may be possible even if the key is outside of the vehicle
and extremely close to a door and window, however, always start the engine
from the driver’s seat.
If the vehicle is started and the key is not in the vehicle, the vehicle will not
restart after it is shut off and the ignition is switched to off.
● The trunk is out of the assured operational range, however, if the key (smart
key) is operable the engine will start.
● The engine may not start if the key is placed in the following areas:
• Around the dashboard
• In the storage compartments such as the glove compartment
• On the rear parcel shelf
If a key is left in the vehicle, the functions of the key left in the vehicle
are temporarily suspended to prevent theft of the vehicle.

Trunk Lid
WARNING
■Never allow a person to ride in the trunk
Allowing a person to ride in the trunk is dangerous. The person in the trunk
could be seriously injured or killed during sudden braking or a collision.
■ Do not drive with the trunk lid open
Exhaust gas in the cabin of a vehicle is dangerous. An open trunk lid in a
moving vehicle will cause exhaust gas to be drawn into the cabin. This gas
contains CO (carbon monoxide), which is colorless, odorless, and highly
poisonous, and it can cause loss of consciousness and death. Moreover, an
open trunk lid could cause occupants to fall out in an accident.
■ Using the trunk
● Before opening the trunk lid, remove any snow and ice accumulation on it.
Otherwise, the trunk lid could close under the weight of the snow and ice
resulting in injury.
● Be careful when opening/closing the trunk lid during strong winds. If a
strong gust blows against the trunk lid, it could close suddenly resulting in
injury.
● Fully open the trunk lid and make sure that it stays open. If the trunk lid is
only opened partially, it could slam shut by vibration or wind gusts resulting
in injury.
● When loading or unloading luggage in the trunk, turn off the engine. Other-
wise, you could get burned by the heat of the exhaust gas.

2-3. Fuel and Emission
2
Before Driving
Fuel and Engine Exhaust Precautions
Vehicles with catalytic converters or oxygen sensors must use ONLY
UNLEADED FUEL, which will reduc e exhaust emissions and keep
spark plug fouling to a minimum.
This vehicle will perform best with fuel listed in the table.
*: U.S. federal law requires that octane ratings be posted on gasoline 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 se rious engine damage.
Gasoline blended with oxygenates such as alcohol or ether com-
pounds are generally referred to as oxygenated fuels. The common
gasoline blend that can be used wi th your vehicle is ethanol blended
at no more than 10 %. Gasoline co ntaining 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.
Fuel Requirements
FuelOctane Rating* (Anti-knock index)
Regular unleaded fuel87 [(R M)/2 method] or above (91 RON or above)
NOTICE
● USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic converter and oxygen sensors and
will lead to deterioration of the emission control system and or failures.
● This vehicle can only use oxygenated fuels containing no more than 10 %
ethanol by volume. Damage to the vehicle may occur when ethanol
exceeds this recommendation, or if the gasoline contains any methanol.
Stop using gasohol of any kind if your vehicle engine is performing poorly.
● Never add fuel system additives, otherwise the emission control system
could be damaged. Consult your Toyota dealer for details.

YARIS iA_OM_OM99N89z_(U)
2-3. Fuel and Emission
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.
● Under U.S. federal law, any modification to the original-equipment emission
control system before the first sale and registration of a vehicle is subject to
penalties. In some states, such modification made on a used vehicle is also
subject to penalties.
● While the engine is off, the sound of a valve opening and closing can be
heard at the rear of the vehicle, however this does not indicate an abnormal-
ity. The vehicle has a selfchecking device and it operates while the engine is
off.
Emission Control System
WARNING
■Never park over or near anything flammable
Parking over or near anything flammable, such as dry grass, is dangerous.
Even with the engine turned off, the exhaust system remains very hot after
normal use and could ignite anything flammable. A resulting fire could
cause serious injury or death.
NOTICE
Ignoring the following precautions could cause lead to accumulate on the
catalyst inside the converter or cause the converter to get very hot. Either
condition will damage the converter and cause poor performance.
●USE ONLY UNLEADED FUEL.
● Do not drive your Toyota with any sign of engine malfunction.
● Do not coast with the ignition switched off.
● Do not descend steep grades in gear with the ignition switched off.
● Do not operate the engine at high idle for more than 2 minutes.
● Do not tamper with the emission control system. All inspections and
adjustments must be made by a qualified technician.
● Do not push-start or pull-start your vehicle.
