5. Retailers must obtain client approval in advance of the upgrade being performed. If client approves,
update the vehicle using the procedure included with this announcement.
NOTE: PC454 applies to new vehicle inventory service action released June 29, 2016. Please refer to
the 3rd. bullet (●) below for additional details.

If a client elects to have a 3G compatible Telematics Control Unit installed, the retailer is responsible
for collecting the co-pay from the client.

Upon completion of the installation of the 3G hardware, retailers will file a warranty claim for the

to Infiniti Connection Plus telematics services included on PC451 & PC452.
o Retailers should still acquire client approval to install the 3G compatible Telematics Control Unit
prior to performing the update.
o Retailers should continue to perform PC454 on applicable vehicles in their inventory.

6. For PC451 and PC452, clients must confirm their participation in the complimentary one (1) year Infiniti
Connection Plus subscription on the Infiniti Owner Portal after installation of the 3G compatible
hardware.

Please provide clients with a copy of the login instructions provided with this announcement. If
possible, retailers should assist clients with this process.

specific procedure.
