the order of off, ACC, and ON.
Pressing the push button start
again from ON switches the igni-
tion off.

start indicator light (amber) also turns off.
In this position the steering wheel is locked.
■ACC (Accessory)
Some electrical accessories will operate and the indicator light
(amber) illuminates.
■ON
This is the normal running position after the engine is started. The
indicator light (amber) turns off. (The indicator light (amber) illumi-
nates when the ignition is switched ON and the engine is not run-
ning.)

When Driving
After starting the engine, let it idle for about ten seconds.
●The key must be carried because the key carries an immobilizer chip that
must communicate with the engine controls at short range.
● The engine can be started when the push button start is pressed from off,
ACC, or ON.
● The push button start system functions (function which can start the engine
by only carrying the key) can be deactivated to prevent any possible
adverse effect on a user wearing a pacemaker or other medical device. If
the system is deactivated, you will be unable to start the engine by carrying
the key. Consult your Toyota dealer for details. If the push button start sys-
tem functions have been deactivated, you can start the engine by following
the procedure indicated when the key battery goes dead.
Refer to Engine Start Function When Key Battery is Dead on P. 145.
● After starting a cold engine, the engine speed increases and a whining
sound from the engine compartment can be heard.
This is for improved exhaust gas purification and does not indicate defect of
the parts.
● Engine-starting is controlled by the spark ignition system.
This system meets all Canadian Interference-Causing Equipment Standard
requirements regulating the impulse electrical field strength of radio noise.
● Under the following conditions, the KEY warning light (red) flashes after the
push button start is pressed to inform the driver that the push button start
will not switch to ACC even if it is pressed from off.
• The key battery is dead.
• The key is out of operational range.
• The key is placed in areas where it is difficult for the system to detect the
signal ( →P. 93).
• A key from another manufacturer similar to the key is in the operational
range.

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.
