SITUATION
If the vehicle has been switched off for a lengthy period of time (longer than 70 minutes), the following Check Control message may appear the next time that the ignition or engine is switched on: "Vehicle battery! Increased battery discharge while stationary (when engine off)". The instrument cluster also displays the appropriate CC symbol (yellow car on lift).

If the off-load current exceeds 80mA after 70 minutes from terminal R off, the CC message above will be displayed.

When troubleshooting for this complaint, always check the vehicle for non-approved after-market accessories.
WARRANTY INFORMATION
Modification of the vehicle; or installation of any non-approved aftermarket performance accessories or components attached to the vehicle which alters the original engineering and/or operating specifications; or which results in damage to other original components, voids the warranty coverage on the affected original components.
