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.

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.

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-
