Fuel and Engine Exhaust Precautions
Vehicles with catalytic converters or oxygen sensors must use O NLY
UNLEADED FUEL, which will reduc e exhaust emissions and keep
spark plug fouling to a minimum.
To achieve maximum engine perfor mance, 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 th e
emission control system to lose e ffectiveness. It could also cause
engine knocking and serious engine damage.
Gasoline blended with oxygenates such as alcohol or ether com-
pounds are generally referred to as oxygenated fuels. The commo n
gasoline blend that can be used with your vehicle is ethanol bl ended
at no more than 10 %. Gasoline containing alcohol, such as etha nol 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 m ore than 10 % ethanol.
• Gasoline or gasohol containing methanol.
• Leaded fuel or leaded gasohol.
Fuel Requirements
FuelOctane Rating*1 (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 se nsors and
will lead to deterioration of the emission control system and o r failures.
● This vehicle can only use oxygenated fuels containing no more t han 10 %
ethanol by volume. Damage to the vehicle may occur when ethanol
exceeds this recommendation, or if the gasoline contains any me thanol.
Stop using gasohol of any kind if your vehicle engine is performing poorly.
● Never add fuel system additives other than a Toyota genuine pro duct, oth-
erwise the emission control system could be damaged. Consult yo ur Toy-
ota dealer for details.

2-4. 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 c omply
with existing exhaust emissions requirements.
●Under U.S. federal law, any modification to the original-equipm ent emission
control system before the first sale and registration of a vehi cle is subject to
penalties. In some states, such modification made on a used veh icle is also
subject to penalties.
● While the engine is off, the sound of a valve opening and closi ng can be
heard at the rear of the vehicle, however this does not indicat e an abnormal-
ity. The vehicle has a selfchecking device and it operates whil e 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 fir e could
cause serious injury or death.
NOTICE
Ignoring the following precautions could cause lead to accumula te on the
catalyst inside the converter or cause the converter to get ver y 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.

Before Driving
Engine Exhaust (Carbon monoxide)
WARNING
■Do not drive your vehicle if you smell exhaust gas inside the v ehicle
Engine exhaust gas is dangerous. This gas contains carbon monox ide
(CO), which is colorless, odorless, and poisonous. When inhaled , it can
cause loss of consciousness and death. If you smell exhaust gas inside the
vehicle, keep all windows fully open and contact your Toyota de aler immedi-
ately.
■ Do not run the engine when inside an enclosed area
Running the engine inside an enclosed area, such as a garage, i s danger-
ous. Exhaust gas, which contains poisonous carbon monoxide, cou ld easily
enter the cabin. Loss of consciousness or even death could occu r.
■ Open the windows or adjust the heating or cooling system to draw
fresh air when idling the engine:
Exhaust gas is dangerous. When the vehicle is stopped with the windows
closed and the engine running for a long time even in an open a rea,
exhaust gas, which contains poisonous carbon monoxide, could en ter the
cabin. Loss of consciousness or even death could occur.
■ Clear snow from underneath and around your vehicle, particularl y the
tail pipe, before starting the engine:
Running the engine when a vehicle is stopped in deep snow is da ngerous.
The exhaust pipe could be blocked by the snow, allowing exhaust gas to
enter the cabin. Because exhaust gas contains poisonous carbon monox-
ide, it could cause loss of consciousness or even death to occu pants in the
cabin.

Fuel-Filler Lid and Cap
WARNING
■When removing the fuel-filler cap, loosen the cap slightly and wait for
any hissing to stop, then remove it
Fuel spray is dangerous. Fuel can burn skin and eyes and cause illness if
ingested. Fuel spray is released when there is pressure in the fuel tank and
the fuel-filler cap is removed too quickly.
■ Before refueling, stop the engine, and always keep sparks and f lames
away from the filler neck
Fuel vapor is dangerous. It could be ignited by sparks or flame s causing
serious burns and injuries.
Additionally, use of the incorrect fuel-filler cap or not using a fuel-filler cap
may result in a fuel leak, which could result in serious burns or death in an
accident.
■ Do not continue refueling after the fuel pump nozzle shuts off automat-
ically
Continuing to add fuel after the fuel pump nozzle has shut off automatically
is dangerous because overfilling the fuel tank may cause fuel o verflow or
leakage. Fuel overflow and leakage could damage the vehicle and if the fuel
ignites it could cause a fire and explosion resulting in serious injury or
death.
NOTICE
Always use only a genuine Toyota fuel-filler cap or an approved equivalent,
available at your Toyota dealer. The wrong cap can result in a serious mal-
function of the fuel and emission control systems.
It may also cause the check engine light in the combination met er to illumi-
nate.

To remove the fuel-filler cap , turn it counterclockwise.
Attach the removed cap to the
inner side of the fuel-filler lid.
Insert the refueling nozzle all the way and begin refueling. Pu ll out
the refueling nozzle after the refueling stops automatically.
To close the fuel-fille r cap, turn it clockwise until a click is heard.
To close, press the fuel-filler lid

NOTICE
If the check fuel cap warning light illuminates, the fuel-filler cap may not be
properly installed. If the warning light illuminates, park your vehicle safely off
the right-of-way, remove the fuel-filler cap and reinstall it c orrectly. After the
cap has been correctly installed, the fuel cap warning light ma y continue to
illuminate until a number of driving cycles have been completed. A drive
cycle consists of starting the engine (after four or more hours with the
engine off) and driving the vehicle on city and highway roads.
Continuing to drive with the check fuel cap warning light illum inated could
cause the check engine light to illuminate as well.

WARNING
■ Make sure that the steering wheel is locked firmly in place
If it is difficult to raise the lever, lightly move the steering wheel forward and
back to pull up the lever.
■ Never adjust the steering wheel while the vehicle is moving
Adjusting the steering wheel while the vehicle is moving is dangerous. Mov-
ing it can very easily cause the driver to abruptly turn to the left or right. This
can lead to loss of control or an accident.
■ After adjusting the steering wheel position, make sure it is se curely
locked by trying to move it up and down
Driving with the steering wheel not securely locked in position is dangerous.
If the steering wheel moves unexpectedly while driving, you cou ld lose con-
trol of the steering resulting in an accident.

What you see in the convex mirror is closer than it appears.
■ Always return the outside mirrors to the driving position before you
start driving
Driving with the outside mirrors folded in is dangerous. Your r ear view will
be restricted, and you could have an accident.
