■Push Button Start Positions
●The engine starts by pressing the push button start while depre ssing the
clutch pedal (manual transaxle) or the brake pedal (automatic t ransaxle). 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 r unning. Doing
so could result in the battery going dead. If the ignition is l eft in ACC (For
automatic transaxle, the selector lever is in the P position, a nd 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 butto n 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 f uel 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 s ure 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, sh ifting 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 leave the vehicle for even a short period, it
is important to switch the ignition off, as leaving it in anoth er position will dis-
able some of the vehicle’s security systems and run the battery down.
