Turning the Engine Off
WARNING
Do not stop the engine while the
vehicle is moving:
Stopping the engine while the vehicle is
moving for any reason other than in an
emergency is dangerous. Stopping the
engine while the vehicle is moving will
result in reduced braking ability due to
the loss of power braking, which could
cause an accident and serious injury.
1. Stop the vehicle completely.
2. (Manual transaxle)
Shift into neutral and set the parking
brake.
(Automatic transaxle)
Shift the selector lever to the P position
and set the parking brake.
3. Press the push button start to turn off
the engine. The ignition position is off.

CAUTION
When leaving the vehicle, make sure the
push button start is off.
NOTE
  The cooling fan in the engine
compartment could turn on for a few
minutes after the ignition is switched
from ON to OFF, whether or not the
A/C is on or off, to cool the engine
compartment quickly.
  When the push button start is pressed
from ON to ACC or OFF, the KEY
indicator light (green) may À ash for
approximately 30 seconds indicating
that the remaining battery power of
the key is low.
 Replace with a new battery before
the key becomes unusable.
 Refer to Key Battery Replacement on
page 6-41 .
  (Automatic transaxle)  If the engine is turned off while the
selector lever is in a position other
than P, the ignition switches to ACC.
Emergency Engine Stop
Continuously pressing the push button
start or quickly pressing it any number of
times while the engine is running or the
