NOTE
ï‚·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

WA R N I N G
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 transaxle) or in 1st gear or R
(manual transaxle):
Leaving the driver's seat without switching
the ignition off, setting the parking brake,
and shifting the selector lever to P
(automatic transaxle) or to 1st gear or R
(manual transaxle) 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.
