Condition/Concern
Questions on ground illumination lamp (puddle lights) operation have been received. SI and the owner's manual are not clear on the operation.
Recommendation/Instructions
For the puddle lamps to operate, "Approach Lighting" must be turned on using the (DIC) Drivers Information Center buttons and it must be dark outside. If both
requirements are met and the unlock button is pressed on the key fob, the puddle lamps will illuminate for approximately 20-30 seconds.
Note: On previous models, the puddle lamps would also illuminate when exiting the vehicle. There was a design change made and the puddle lamps will no
longer illuminate when exiting the vehicle, unless the unlock button is pressed on the key fob.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may
occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools,
safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that
your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
