Infiniti Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained individuals
who have the equipment, tools, safety instruction, and know-how to do a job properly and safely. NOTE: If you believe that a described
condition may apply to a particular vehicle, DO NOT assume that it does. See your Infiniti retailer to determine if this applies to your
vehicle.

information about the issue as possible from the service advisor/writer or customer.

during the concern. Gather model and software version information if possible.
