When Driving
Start/Stop Engine
Ignition Switch
Push Button Start Positions
The system operates only when the key is
within operational range.
Each time the push button start is pressed,
the ignition switches in the order of off,
ACC, and ON. Pressing the push button
start again from ON switches the ignition
off.
NOTE
The engine starts by pressing the push

button start while depressing the clutch
pedal (manual transmission) or the
brake pedal (automatic transmission).
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 transmission, the
selector lever is in the P position, and
the ignition is in ACC), the ignition
switches off automatically after about
25 minutes.

Indicator light
Off
The power supply to electrical devices
turns off and the push button start indicator
light (amber) also turns off.
In this position the steering wheel is
locked.
WARNING
Before leaving the driver's seat, always
switch the ignition off, set the parking
brake, and make sure the selector lever
is in P (automatic transmission) or in 1st
gear or R (manual transmission):
Leaving the driver's seat without
switching the ignition off, setting the
parking brake, and shifting the selector
lever to P (automatic transmission) or
to 1st gear or R (manual transmission)
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 another position will
disable some of the vehicle's security
systems and run the battery down.
ACC (Accessory)
Some electrical accessories will operate
and the indicator light (amber) illuminates.
NOTE
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.
