PRELIMINARY INFORMATION
Subject:
DIC Activated Maintenance Service Menu May Not Be Synchronized with Oil Life
Monitor (North American Market Only)
Models:
2014 Buick LaCrosse, Regal
2014 Cadillac ATS, CTS, ELR, SRX, XTS
2014 Chevrolet Corvette, Silverado 1500
2014 GMC Sierra 1500
Condition/Concern
Certain 2014 vehicles have been released with IPC/cluster software that has the ability to display a service
maintenance menu. This menu is currently turned off in all vehicles as delivered, but has the ability to be activated
by the customer in the DIC setting menu. If activated, it will count down from 7,500 miles (12,000 km) and tell the
user to go to the dealer when it approaches 0 miles/km. This information may conflict with the oil life monitor and
may cause confusion among customers as to which service screen is correct.
The graphic below indicates some additional information about the operation of the service screen.

Recommendation/Instructions
If a customer comes in with the service menu activated, has questions about the menu or is confused to what it is
used for, the technician may calibrate off the menu through SPS and indicate to the customer that it mimics or is a
duplicate of the Oil Life Monitor and has been eliminated to prevent any future confusion.
Important: DO NOT replace the instrument cluster for this condition.
