Vehicles delivered to dealers since December are equipped with two battery saving features: “Extended Storage Switch” and “BCM Transit Mode”. Failure to disable either battery saving feature prior to customer delivery will result in improper operation of various vehicle electrical components leading to Customer Dissatisfaction.

Extended Storage Switch (ESS) is located in the fuse panel. ESS is a removable fuse that when pulled out disables several electrical functions. Vehicles are shipped to dealers with the fuse pulled out to retain battery charge. Dealerships are required to push in the fuse prior to customer delivery.

BCM Transit mode is a Body Control Module setting that also disables vehicle electronic features. Vehicles are shipped to dealers with the BCM transit mode enabled. Simultaneously pushing down on the wiper switch and turn signal for 2 seconds will disable the BCM transit mode. Dealerships are required to disable the BCM transit mode prior to customer delivery.

Failure to disable either feature will lead to the following customer symptoms:
- Keyfob Inop (keyless remotes do not lock or unlock doors/trunk)
- Heater/Air Conditioning blower stuck on high (default position when vehicle is started)
- Heater/Air Conditioning unable to retain temperature setting memory
- HomeLink Inop (garage door opener located in rearview mirror can not be programmed)
- Clock Inop
- Hazard Lights stay on for 1 minute (both turn indicators stay lit on meter)
- Interior Lights Inop
- Fog Lamp Inop
- Panic Alarm Inop

Please ensure that both battery saving features are disabled before delivering vehicles to customers.

Claims for the items mentioned above should not be submitted if found to be a result of ESS or BCM transit mode operation.
