Ignition Positions - Chevrolet TrailBlazer 2007 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.
B (ACCESSORY): This position lets you use
things like the radio and the windshield wipers
when the engine is off.
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.
The battery could be drained if you leave the key
in the ACCESSORY or 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.
