How to Get Your GMC Out of Demo Mode
If your GMC's infotainment screen keeps cycling through feature demonstrations, shows a demonstration watermark, or has certain functions oddly restricted, it's likely still configured in Demo (Showroom) mode — a dealership setting meant to showcase the vehicle's features on the lot that should be switched to Retail mode before delivery.

Why This Setting Exists
Demo mode lets dealership staff showcase features automatically without manually demonstrating every function to each customer on the lot. It's designed to be switched off during delivery prep, but on occasion it's missed, leaving the new owner with a vehicle still behaving like a showroom display unit.
Where to Find the Setting
On most GMC infotainment systems, look under Settings, then a General or Vehicle submenu, for an option labeled Retail/Demo Mode or similar. The exact menu path can vary slightly depending on your specific infotainment version.
Switching to Retail Mode
Selecting Retail mode and confirming the change should stop the automatic feature cycling and remove any demonstration watermark, typically taking effect on the next screen refresh or system restart.
When to Contact Your Dealer
If the setting isn't visible in your menus, or changing it doesn't actually alter the vehicle's behavior, the setting may be locked at a level only your selling dealer's diagnostic tool can access. This is a quick, no-cost fix for them and worth raising directly rather than assuming it's a hardware issue.

Frequently Asked Questions
Does demo mode affect how the vehicle drives?
No — it's purely an infotainment display and feature-showcase setting, and it has no effect on engine, transmission, or drivetrain performance.
Is it common for dealers to miss switching this off?
It happens occasionally during the delivery process, and most dealers will correct it quickly and at no charge once it's brought to their attention.
Will a battery disconnect switch it back to Retail mode?
Not typically — demo mode is a stored configuration setting rather than a temporary state, so a battery disconnect generally won't reset it on its own.
Should I be concerned this indicates a bigger problem?
No — it's simply an overlooked delivery step rather than a sign of any underlying mechanical or electrical issue with the vehicle.
