Ignition Positions; Retained Accessory Power (Rap) - Chevrolet 2006 TrailBlazer EXT 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: If your key seems stuck in LOCK and you
cannot turn it, be sure you are using the correct key;
if so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break the
key or the ignition switch. If none of these works,
then your vehicle needs service.
2-20
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)

Your vehicle is equipped with a Retained Accessory
Power (RAP) feature which will allow certain features of
your vehicle to continue to work up to 20 minutes
after the ignition key is turned to LOCK.
Your radio, power windows, sunroof (option) and
overhead console will work when the ignition key is in
RUN or ACCESSORY. Once the key is turned from
RUN to LOCK, these features will continue to work for
up to 20 minutes or until a door is opened.
