2. Master Your Advanced Camera Systems

Your GMC Sierra isn't just watching the road - it's got eyes all around. Let's check out some camera features you might've missed.

Did you know that with the flip of a switch, your rearview mirror turns into a wide-angle camera view? No more headrests or cargo blocking your view. And it even has its little washer to keep things clear.

Now, about that truck bed. There's a camera up there too! The Bed View Camera lets you keep an eye on your cargo or helps you hook up a fifth wheel without breaking a sweat.

Parking in tight spots? Your Sierra's got you covered with Front and Rear Park Assist Cameras. They beep and show you how close you are to obstacles, and they even look out for pedestrians up front.

Here's a neat trick: when you hit your turn signal, cameras in your side mirrors show you what's in your blind spot. All these cameras work together to give you a bird's-eye view of your truck.

3. Clever Storage & Charging Tricks

Your Sierra is hiding more than you might think when it comes to storage and charging options. Let's start with those useful USB ports. They're tucked away all over the place.

In the center console, you'll find a mix of USB-A and USB-C ports hiding under trays or behind little doors. These aren't just for charging - they can handle data transfer, too, which is great for media playback or system updates.

Check out the glove box - there's a USB port in there too. It's perfect for charging devices out of sight.

And don't forget to look in the dash compartment. There's often a hidden port there that's ideal for powering a dash cam without messy wires everywhere.

Now, let's talk storage. Your Sierra's got some clever hiding spots. Under the rear seats, you'll find modular storage compartments. Some even come with dividers and organizers to keep everything in its place.

If you've got valuables, look for the lockable compartments - they're great for tools or emergency kits. The center console is like a mini storage unit. Lift out the trays, and you'll find deeper storage areas underneath.

Some of these compartments have removable liners, making them easy to clean or customize. And don't overlook the glove box - there's often an extra compartment in there for important documents.

But the storage solutions don't stop in the cab. Check out the cargo bed - you might find hidden compartments along the sides or under the floor. Some even have drain plugs, which are handy for storing wet or muddy items.

4. Next-Level Trailering Features

Let's talk about your ProGrade Trailering System. One standout feature is the Trailer Light Test. Instead of needing someone else to help, you can check all your trailer lights by running through the entire sequence from your driver's seat.

And if someone tries to unhitch your trailer while you're away, the Trailer Theft Detection will send an alert straight to your phone.

The Invisible Trailer View system uses cameras to create a "see-through" effect on your infotainment screen, allowing you to see what's behind your trailer.

For optimal performance, keep all cameras calibrated. You can also adjust the transparency and field of view to match your preferences.

Additionally, the Trailer Tire Pressure Monitoring System (TPMS) goes beyond just tracking tire pressure; it also monitors temperature. This is useful because it helps you spot potential issues before they become serious problems.

You can also set custom thresholds for both pressure and temperature, getting alerts if something's off.

This data appears alongside your truck's tire information, providing a complete overview of your tires' health and ensuring safer and more efficient towing.

5. Smart Tricks for Your Key Fob

Your Sierra's key fob is hiding some impressive tricks. Did you know you can use it to open and close the power tailgate?

You can even stop it at any position by pressing the button again. This is great for loading in tight spaces or low-ceiling garages.

Additionally, hold down the unlock button to lower all your windows at once - perfect for hot days when you want to air out the cabin before getting in. Some models even let you raise the windows by holding the lock button.

The panic alarm feature has a hidden mode. Instead of blaring the horn, you can set it to silent mode. This sends notifications to your phone without drawing attention to your vehicle.

Your key fob can also detect when it's close to the vehicle, allowing for automatic locking and unlocking. You can even set it to activate exterior and interior lights when you approach—no more fumbling in the dark.

One of the most overlooked features is the ability to customize the key fob buttons. Through the infotainment system, you can assign different functions to each button.

Want quick access to the rear hatch? Assign it to a long press of the unlock button. The possibilities are numerous.

6. Customizing Teen Driver Features

Have you wondered about the options customizable for your teen driver? Your GMC Sierra's Teen Driver feature offers several tools to help your teen drive safely.

You can set up speed alerts to notify your teen when they're driving too fast. If the music is too loud, you can limit the volume through the infotainment system.

You can even secure these settings with a PIN so that others cannot alter them. For added convenience, link the Teen Driver settings to a specific key fob. This way, the truck automatically adjusts when your teen is driving.

The 'Buckle to Drive' feature is another useful tool. The truck won't shift out of park until the driver buckles up. For extra peace of mind, you can use OnStar services to monitor their location and even get real-time alerts on your phone.

7. Personalized Lighting Features

The lighting features in your GMC Sierra are designed for convenience and safety. The headlights automatically switch between high and low beams, providing optimal visibility without blinding other drivers.

Additionally, some models work with the GPS to adaptively illuminate curves before you reach them, enhancing your driving experience on winding roads.

Inside the cabin, the Sierra offers customizable ambient lighting. You can select your preferred color and even sync it with your drive mode using the infotainment system.

Whether you want a calming blue or an energizing red, the choice is yours.

For nighttime loading, the truck bed is equipped with lights that can be activated via the key fob, giving you ample illumination without needing a flashlight.

Additionally, the puddle lamps near the doors can project a custom logo on the ground, adding a personal touch every time you approach your vehicle.

Lastly, the Sierra is equipped with specialized fog lights designed for visibility in misty conditions. Some models include yellow fog lights, which are particularly effective at cutting through dense fog.

8. Tailor-Made Driving Profiles

Your truck can recognize you by your key fob and automatically adjust settings to your preferences.

You can set up profiles for different drivers, ensuring your seat position, mirror settings, and climate controls are just how you like them every time you get in.

The customizable instrument cluster allows you to rearrange digital gauges, choose the information you want to see, and set up different layouts for various driving situations.

For instance, you can prioritize monitoring transmission temperature when towing or keep an eye on fuel economy during commutes.

Additionally, you can sync the ambient lighting with your driving mode or have it pulse with your music for an enhanced driving experience.

These features provide a personalized and intuitive driving experience tailored to your specific needs and preferences.

Your Sierra's steps and running boards offer more than just basic functionality. For those times when you need the steps extended longer, such as when washing your vehicle, you can manually override the automatic settings.

There is also a service position mode to keep the steps extended during maintenance. These features can typically be accessed through a switch inside the cabin or via the vehicle's settings in the infotainment system.

The integrated LED lighting in the running boards and steps is another valuable feature. You can manually control these lights through the infotainment system or a dedicated switch and adjust their brightness to suit your needs.

10. MyGMC App Mastery

The MyGMC app offers features that go beyond basic remote start and vehicle location. One notable feature is the ability to schedule remote starts.

You can set specific times for your Sierra to start, ensuring it's comfortable when you're ready to go. You can also adjust the duration so that it runs long enough.

Navigation is simplified with the ability to send destinations directly from the app to your vehicle's infotainment system.

For parents of teen drivers or fleet managers, geofencing zones can be set up to receive alerts when the vehicle enters or exits predefined areas.

Another useful feature is the ability to manage multiple GMC vehicles. This allows you to maintain and monitor all your vehicles from one app, making vehicle management more convenient and efficient.

11. Smarter Cruise Control Options

Your Sierra's cruise control has several advanced features beyond maintaining speed. The Adaptive Cruise Control (ACC) uses sensors to adjust your speed automatically to maintain a safe following distance from the vehicle ahead.

The Predictive Cruise Control feature uses map data to anticipate curves and hills, adjusting your speed for smoother, more efficient driving. If there's a long downhill stretch, it eases off the gas to save fuel. It can also start slowing down before you reach busy areas.

To maximize its benefits, keep your navigation system updated and consider enabling eco mode for better fuel savings.

The lane-centering feature helps reduce driver fatigue on long trips by making small steering adjustments. You can adjust its sensitivity to match your driving style, ensuring a more natural feel.

Dynamic Radar Cruise Control can handle stop-and-go traffic by bringing your Sierra to a complete stop and then moving again when traffic flows, all without you touching the pedals. This is especially useful in rush hour traffic.

The Driver Attention Alert system monitors your driving patterns and detects when you're not driving as usual. You can customize the sensitivity and types of alerts and set up scheduled break reminders for long trips.

This weatherproof system lets you enjoy tunes without draining your truck's battery, with controls conveniently located on the tailgate itself.

13. Adaptive Off-Road Systems

The Terrain Management System in your Sierra goes beyond selecting a mode for mud or sand. This system learns your driving habits over time and fine-tunes its performance to match your style.

You can access the settings and tweak specific parameters for each mode, customizing the experience to suit your preferences.

Auto 4WD Mode is a lesser-known feature that constantly monitors driving conditions, switching between two-wheel and four-wheel drive as needed.

This provides optimal traction without any manual intervention and helps save fuel by only engaging 4WD when necessary. You can adjust its sensitivity through the infotainment system to match your preferences.

The off-road suspension system on some models allows you to adjust your ride height on the fly. Need more clearance for a rocky trail? Raise it.

Want better stability for a fast dirt road? Lower it down. This flexibility gives you the ability to tackle various terrains with ease.

The off-road lighting system is more advanced than many realize. You can program different light patterns for different situations.

Whether you need a widespread beam for slow rock crawling or a focused beam for high-speed desert runs, the system can be customized to meet your needs.
