GMC 2007 Canyon - Manual (Page 116)

Ignition Positions
With the key in the
ignition switch, you can
turn to four different
positions.
LOCK (A): This position locks the ignition. It also
locks the transmission on automatic transmission
vehicles. It will locks the steering wheel on
manual transmission vehicles when the key is
removed. It is a theft-deterrent feature. You
will only be able to remove your key when the
ignition is turned to LOCK.
If you have an automatic transmission, the ignition
switch cannot be turned to LOCK unless the
shift lever is in PARK (P).
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 all the
way in. If it is, turn the steering wheel left and
right while you turn the key hard. If none of this
works, then your vehicle needs service.
ACC (ACCESSORY) (B): This is the position in
which you can operate your electrical accessories
or items plugged into the accessory power
outlets. On automatic transmission vehicles,
this position unlocks the ignition. On manual
transmission vehicles, it unlocks the ignition and
steering wheel. Use this position if your vehicle
must be pushed or towed.
ON (C): This is the position that the switch
returns to after you start your engine and release
the switch. The switch stays in ON when the
engine is running. But even when the engine is
not running, you can use ON to operate the
electrical accessories and to display some
instrument panel cluster warning and indicator
lights. The transmission is also unlocked in
this position on automatic transmission vehicles.
