*This bulletin does not apply to aftermarket remote start kits that have been installed, vehicles that are not listed above, vehicles with additional remotes that are
not part of an official GM accessories remote start kit, vehicles with RPO AP8, and/or vehicles listed above that do not have an official GM Accessory remote
start kit available for them at this time. This bulletin only applies to models above that have had an official GM Accessory remote start kit installed/programmed
at a GM dealership. At this time, some of the models listed above may not have an official GM accessory remote start kit available for them – always confirm kit
availability with your GM dealership parts department using the customer’s actual VIN number and ensure that they are looking up an actual GM Accessory
remote start kit for that VIN, not individual replacement remotes that are not part of a GM Accessory remote start kit. Also note that some 2010 model year
VINs, Malibu fleet vehicles, and Impala fleet vehicles may not have the capability to allow the MyBuick, MyCadillac, MyChevrolet and MyGMC phone applications
to be enabled.

Excluding Vehicles Equipped with Remote Ready Start Package (RPO AP8)

Condition

Historically, MyBuick, MyCadillac, MyChevrolet, MyGMC, and OnStar® RemoteLink phone applications
would not work on vehicles that had a GM accessory remote start kit installed. To provide a better customer
experience, GM recently developed an automated process to activate the MyBuick, MyCadillac, MyChevrolet
and MyGMC phone applications.
Whenever a customer purchases a GM accessory remote start kit, has it installed on any of the vehicles
listed above, and has their vehicle programmed to activate the remote start, the related VIN is added to a list
which is feed to the OnStar team on a weekly basis. Within 10 days of vehicle programming, the OnStar
team then enters all of this VIN info into their database, which will automatically enable the MyBuick,
MyCadillac, MyChevrolet, MyGMC phone applications once the customer downloads them to their device,
opens an account, and accepts terms and conditions.

Important: An active OnStar subscription is required.
As described above, the MyBuick, MyCadillac, MyChevrolet, and MyGMC phone applications should typically be ready for use within 10 days of having the
vehicle programmed and GM accessory remote start kit activated. If the customer downloads the MyBuick, MyCadillac, MyChevrolet or MyGMC phone
2

application and finds that they cannot operate the remote start system with any of these phone applications, it is important to confirm that at least 10 days have
passed since the date of vehicle programming just to ensure that sufficient time has passed for the phone app activation process to take place. If they have
waited at least 10 days and the phone application still does not operate the GM accessory remote start kit, the customer should contact OnStar by pressing the
blue OnStar button or a Connection Center Advisor (877-558-8352) to have the phone application manually activated.

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.
