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 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.

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.

This is the normal running position after
the engine is started. The indicator light
(amber) turns off. (The indicator light
(amber) illuminates wh en the ignition is
switched ON and the engine is not
running.)
