Ignition Positions; Retained Accessory Power (Rap) - Chevrolet 2005 Express Van Owner's Manual

Ignition Positions

Use the key to turn the ignition switch to four different
positions.
A (Lock): This position locks the ignition and
transmission. It is a theft-deterrent feature. You will only
be able to remove the key when the ignition is turned
to LOCK.
Notice: Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is in all the way. If
none of this works, then your vehicle needs service.
B (Accessory): This position lets you use things like
the radio and the windshield wipers when the engine
is off.
Notice: Lengthy operation of features such as the
radio in the accessory ignition position may
drain the battery and prevent your vehicle from
starting. Do not operate your vehicle in the
accessory ignition position for a long period
of time.
C (Run): This is the position for driving.
D (Start): This position starts the engine.

Retained Accessory Power (RAP)

The Retained Accessory Power (RAP) feature will allow
certain features on your vehicle to continue to work
for up to 10 minutes after the ignition key is turned to
LOCK or until one of the doors is opened.
