Service Bulletin

SERVICE UPDATE
SUBJECT:

Service Update for Inventory and Customer Vehicles
Inspect Air Conditioning Refrigerant Warning Label
Expires with Base Warranty

MODELS:

2015 Cadillac Escalade Models
2015 Chevrolet Suburban
2015 GMC Yukon Models
Middle East Exports Only

This service update includes vehicles in dealer inventory and customer vehicles that return to the
dealership for any reason. This bulletin will expire at the end of the involved vehicle's New Vehicle
Limited Warranty period.
PURPOSE
This bulletin provides a service procedure to inspect the air conditioning refrigerant warning label
on certain 2015 Cadillac Escalade vehicles, 2015 Chevrolet Suburban vehicles, and 2015 GMC
Yukon vehicles. If the label is incorrect, this bulletin provides a service procedure to replace the
label, inspect the air conditioning refrigerant charge, and adjust the air conditioning refrigerant
charge. In extremely high ambient temperatures in the Middle East, poor air conditioning
performance may be experienced if the air conditioning system was overcharged at the assembly
plant as a result of the incorrect label.
This service procedure should be completed as soon as possible on involved vehicles
currently in dealer inventory and customer vehicles that return to the dealer for any type
of service during the New Vehicle Limited Warranty coverage period.
VEHICLES INVOLVED
All involved vehicles are identified by VIN in the Global Warranty Management System –
Investigate Vehicle History Application. Dealership technicians should always check this site to
confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is
important to routinely use this tool to verify eligibility because not all similar vehicles may be
involved regardless of description or option content. Customer vehicles that return for service, for
any reason, and are still covered under the vehicle's base warranty should also be checked for
vehicle eligibility.

PART INFORMATION
The correct label required to complete this service update is being distributed directly to all dealers
starting July 1, 2014 based on the affected VIN numbers in each dealer’s inventory. If additional
labels are needed, contact your local aftersales wholesale support center (MEO).
SERVICE PROCEDURE
Example of Air Conditioning Refrigerant Warning Label with 0.92 kg Correctly Displayed

3956173

1.

Open the hood and inspect the air conditioning (A/C) refrigerant warning label shown above
to ensure that it is correct.



If the refrigerant charge is listed as 0.92 kg as shown above, the air conditioning (A/C)
refrigerant warning label is correct and no further action is required.
If the refrigerant charge is NOT listed as 0.92 kg, it is incorrect. Proceed to step 2.

Warning: If the proper recovery and recharge procedure is not followed, the vehicle may come
back with poor A/C performance. It is critical not to under-fill or over-fill the A/C system – the
correct amount of 0.92 kg must be used to ensure proper performance. As always, it is important
to ensure that the A/C machine is properly calibrated to ensure an accurate charge. Do not push
the remaining A/C refrigerant into the system; once the A/C machine stops and displays that the
correct charge has been obtained, simply remove the connections from the vehicle.
2.

Completely recover the entire amount of original refrigerant from the air conditioning system
and recharge it with the recovered refrigerant but exactly to the specified quantity of 0.92 kg
only. Refer to Refrigerant Recovery and Recharging (R-134a) in SI.

3.

Replace the incorrect air conditioning refrigerant warning label using the correct label
described above.

DEALER PROGRAM RESPONSIBILITY
Whenever a vehicle subject to this service update enters your vehicle inventory, or is in your facility
for service in the future, and the vehicle is still covered under the New Vehicle Limited Warranty,
you must take the steps necessary to be sure the service update correction has been made before
selling or releasing the vehicle.

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 tools,
equipment, 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 dealer for information on whether your vehicle may benefit from the information.
