1. Indicator light
2. Push button start
NOTE
The engine starts by pressing the
push button start while depressing
the brake pedal. 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 selector lever is in
the P position, and the ignition is in
ACC, the ignition switches off
automatically after about 25
minutes.
Off
The power supply to electrical devices
turns off and the indicator light
(amber) also turns off.
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 position:
Leaving the driver's seat without
switching the ignition off, setting the
parking brake, and shifting the selector
lever to P position 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.
