Retained Accessory Power (Rap) - Buick Enclave 2008 Owner's Manual

A (LOCK/OFF): This is the only position in which you
can remove the key. This position locks the ignition and
transmission. If the steering wheel is locked, move it
from right to left and turn the key to ACC/ACCESSORY.
If none of this works, then your vehicle needs service.
B (ACC/ACCESSORY): This position allows you to
use things like the radio and the windshield wipers while
the engine is off. This position will also allow you to
turn off the engine.
C (ON/RUN): This is the position that the switch
returns to after you start your engine and release the
key. The switch stays in ON/RUN when the engine
is running. But even when the engine is not running,
you can use ON/RUN to operate your electrical power
accessories, and to display some instrument panel
warning lights.
The battery could be drained if you leave the key in
the ACC/ACCESSORY or ON/RUN position with
the engine off. You may not be able to start your
vehicle if the battery is allowed to drain for an
extended period of time.
D (START): This position starts the engine. When
the engine starts, release the key. The ignition switch
will return to ON/RUN for normal driving.
Key In the Ignition
Never leave your vehicle with the keys inside, as it is an
easy target for joy riders or thieves. If you leave the key in
the ignition and park your vehicle, a chime will sound
when you open the driver's door. Always remember to
remove your key from the ignition and take it with you.
This will lock your ignition and transmission. Also, always
remember to lock the doors.
The battery could be drained if you leave the key in the
ignition while your vehicle is parked. You may not be
able to start your vehicle after it has been parked for an
extended period of time.
