Retained Accessory Power (Rap); Starting The Engine - GMC Sierra 2005 Owner's Manual

Key Release Button
(Manual Transmission)
To remove the key on manual transmission vehicles,
turn the key to ACCESSORY, then press the button
and turn the key to LOCK. Do not hold the button
in while turning the key to ACCESSORY. Pull the
key straight out.

Retained Accessory Power (RAP)

If the vehicle has Retained Accessory Power (RAP),
certain features will continue to operate for up to
10 minutes after the ignition key is turned to LOCK
unless a door is opened.
The ignition key cannot
be removed from the
ignition of manual
transmission vehicles
unless the key release
button is used.

Starting the Engine

Your vehicle is equipped with Starter Motor Control.
This feature assists in starting the engine and protects
the electrical system. This feature may cause the
engine to crank even after the ignition key is not
in START.
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that
is a safety feature. To restart when you are already
moving, use NEUTRAL (N) only. If you have a diesel
engine refer to the diesel supplement for the starting
procedure.
Notice: Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
Manual Transmission
The gear selector should be in neutral and the parking
brake engaged. Hold the clutch pedal to the floor
and start the engine. Your vehicle will not start if the
clutch pedal is not all the way down — that is a safety
feature.
