Unlocking the Hidden Features of the GMC Sierra 1500 Denali Ultimate
Hey everyone, if you are hunting for a premium truck and live within a four-hour drive of our lot at 4126 Oregon Pike in Ephrata, PA, Mark Martin Motors has you covered. We regularly welcome folks from across Pennsylvania, Maryland, New Jersey, and New York who make the trip to find exactly what they want. Today, we are walking through the 2024 and newer GMC Sierra 1500 Denali Ultimate to uncover some amazing factory features that most owners completely miss.
The Ultimate Tailgate Setup
Built-in Kicker Audio
The Multi-Pro tailgate on this truck hides a fully waterproof, marine-grade Kicker sound system. It operates completely independently of the engine with a very low battery draw. Once you pair your phone via Bluetooth, you get an impressively loud audio system that is absolutely perfect for tailgating, camping, or just hanging out around the job site.
Secret Bed Step Extension
If you look at the back of your power running boards, there is a small button located near the rear tire. Just tap it with your foot and the running board will extend outward toward the bed. It gives you a quick, convenient step to reach over the side of the truck bed without having to drop the whole tailgate down.
Performance and Tech Upgrades
Factory Active Exhaust
If you leave this truck in normal driving mode, you are missing out on one of its best features. Starting with the 2024 models, switching the drive mode dial into sport opens up active baffles in the exhaust. It instantly gives the truck a deep, aggressive rumble that sounds like a custom aftermarket setup, while also giving you sharper throttle response.
Super Cruise Camera Washer
This truck is equipped with full self-driving Super Cruise, which incredibly still works even when you have a trailer hooked up. To make sure the system always has a clear view, GMC built a hidden washer fluid nozzle into the front-facing camera. Whenever you wash your windshield, it automatically sprays and cleans that front camera too.
Smart Interior Controls
Digital Rearview Mirror
When you have a cab full of passengers or cargo blocking your view out the back window, simply flip the tab on your standard rearview mirror. It immediately turns into a high-definition camera display giving you an unobstructed view behind the truck. You can easily adjust the brightness, height, and zoom right from the mirror buttons.
Key Fob Window Control
On hot days, you can roll down all your windows before you even open the door. Just press the unlock button on your key fob twice, holding it down on the second press. Just make sure the remote window operation feature is turned on in your infotainment settings first.
