the doors.
●Start the engine with the engine
switch in ACC. T he engine may
not start with th e engine switch
turned off. However, the engine
will operate normally from the sec-
ond attempt.
●The engine switch mode is
recorded by the vehicle. If the bat-
tery is disconnected and recon-
nected, the vehicle will return the
engine switch mode to the status it
was in before the battery was dis-
connected. Make sure to turn off
the engine before disconnecting
the battery. Take extra care when
connecting the battery if the
engine switch mode prior to the
