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.

Fuel-Filler Lid and Cap
WARNING
■When removing the fuel-filler cap, l oosen 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 engi ne, and always keep sparks and flames
away from the filler neck
Fuel vapor is dangerous. It could be ignited by sparks or flames causing
serious burns and injuries.
Additionally, use of the incorrect fuel-fil ler 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 overflow 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 meter to illuminate.

When Driving
■Push Button Start Positions
●The engine starts by pressing the push button start while depressing the
clutch pedal (manual transaxle) or the brake pedal (automatic transaxle). To
switch the ignition position, press the push button start without depressing
the pedal.
● Do not leave the ignition switched ON while the engine is not running. Doing
so could result in the battery going dead. If the ignition is left in ACC (For
automatic transaxle, the selector lever is in the P position, and the ignition is
in ACC), the ignition switches off automatically after about 25 minutes.
■ ACC (Accessory)
The keyless entry system does not function while the push button start has
been pressed to ACC, and the doors will not lock/unlock even if they have
been locked manually.
■ ON
When the push button start is pressed to ON, the sound of the fuel pump
motor operating near the fuel tank can be heard. This does not indicate an
abnormality.
WARNING
■Before leaving the driver’s seat, set the parking brake, make sure the
selector lever is in 1st gear or R (manual transaxle) or in P (automatic
transaxle), and always switch the ignition off
Leaving the driver’s seat without setting the parking brake, shifting the
selector lever to 1st gear or R (manual transaxle) or to P (automatic tran-
saxle), and switching the ignition off is dangerous. Unexpected vehicle
movement could occur which could result in an accident.
In addition, if your intention is to l eave the vehicle for even a short period, it
is important to switch the ignition off, as leaving it in another position will dis-
able some of the vehicle’s security systems and run the battery down.

3-1. Start/Stop Engine
●Forced engine starting method:
If the KEY warning light (red) illuminates, or the push button start indicator
light (amber) flashes, this could indicate that the engine may not start using
the usual starting method. Have your vehicle inspected at your Toyota
dealer as soon as possible. If this occurs, the engine can be force-started.
Press and hold the push button start until the engine starts. Other proce-
dures necessary for starting the engine such as having the key in the cabin,
and depressing the clutch pedal (manual transaxle) or the brake pedal
(automatic transaxle) are required.
● When the engine is force-started, the KEY warning light (red) remains illumi-
nated and the push button start indicator light (amber) remains flashing.
● Automatic transaxle:
When the selector lever is in the neutral (N) position, the KEY indicator light
(green) and the push button start indicator light (green) do not illuminate.
● After pressing the push button start and before the engine starts, the opera-
tion sound of the fuel pump motor from near the fuel tank can be heard,
however, this does not indicate a malfunction.
● Whether the engine is cold or warm, it should be started without the use of
the accelerator.
● If the engine does not start the first time, refer to Starting a Flooded Engine
under Emergency Starting. If the engine still does not start, have your vehi-
cle inspected by your Toyota dealer ( →P. 494).
WARNING
■Radio waves from the key may affect medical devices such as pace-
makers
Before using the key near people who use medical devices, ask the medical
device manufacturer or your physician if radio waves from the key will affect
the device.
NOTICE
If the KEY warning light (red) illuminates, or the push button start indicator
light (amber) flashes, this could indicate a problem with the engine starting
system and the inability to start the engine or switch the ignition to ACC or
ON. Have your vehicle inspected at your Toyota dealer as soon as possible.
