2025 GMC Sierra Denali EV pickup truck in silver parked on a scenic cliff overlooking the ocean, showcasing luxury electric power, available at Speck Buick GMC of Tri-Cities in Kennewick, WA.

GMC designed Multi-Pro Tailgate to accommodate your life. It has a primary and secondary gate, first of which folds like an ordinary tailgate, and the second folds again to create a multitude of options. These options include wide 48″ entry steps, bed extender, and more!

The Tailgate We Know and Love

The new Sierra comes equipped with high tech capabilities, including those that control the tailgate! Open the Multi-Pro by pressing a simple button on the tailgate itself, on your key fob, or from the inside of your truck with a button found on the instrument panel. This will open the tailgate smoothly and quickly into the traditional back-end style we are all familiar with.

Bringin’ Out the Paddleboards

Open up the tailgate, you’ll notice a foldable panel on the inside. Lift it up, and you have a bed extender! Make the most out of your haul with this feature!

Cut Out the Middle Man

Need to reach your cargo but your tailgate’s in the way? Get closer by releasing the secondary tailgate. Pressing the extra button will drop the second part of your gate, which gives you about 7-9 inches of extra reaching space.

Step Up Your Tailgate Game

Press both buttons on the tailgate simultaneously to drop both parts of the door. Fold down the extra panel (same one that is folded for a bed extender), and you have easy access steps that can hold up to almost 375 pounds. Perfect for a big move or large haul.

Make Everywhere Your Workspace

Just fold down the secondary gate! By just pressing the secondary button, there is a workspace ready for your projects. There is also an available 120-volt electrical in-bed outlet that can make it easier to get the job done. We definitely recommend a camping cook spot!

coolant guage

Your car overheating can mean a few different things, but oftentimes it can be a leak or blockage. This results in the engine’s cooling system preventing heat from properly escaping.

Make sure you have a few things in your car ready just in case:

  • coolant (50/50 antifreeze & water)
  • oil
  • extra water
  • heavy duty gloves
  • tools

Signs you car is overheating include:

  • temperature gauge getting close to or in the red
  • burning or strange smell coming from front of vehicle
  • steam coming from the boiling coolant

The best thing to do when you notice your car overheating on the road is to pull over and turn off your engine to avoid engine damage and wait for your engine to cool down (at least 15 minutes) before you approach it. When checking under the hood pay attention to the coolant and oil levels, as well as any visible disconnection, cracks or leaks within the system. Top off your coolant and oil, and use distilled water as a temporary, emergency replacement for the coolant. If you believe you cannot drive it safely any longer, call your tow service.

If you’re on the road and notice your temperature gauge begins to go up abnormally, turn on the heater at full blast. Even if it’s a hot day, this can direct the heat away from your engine. Even if this does work, you should only drive a small distance. This can only be a band-aid for your vehicle overheating and it should be taken to a mechanic as soon as possible.

If you experience your car overheating, please give us a call here at Speck Buick GMC so we can get your vehicle back on the road safely!

2025 GMC Sierra HD Denali in white towing a large fifth-wheel RV through a scenic mountain road, showcasing powerful towing capability, available at Speck Buick GMC of Tri-Cities in Kennewick, WA.

Keep These Pointers in Tow:

Know your weight limits and read your trailering guide!

It’s important to understand the weight capacity of your vehicle’s towing capability. A lot of factors can determine the trailering limit of a vehicle from the engine, cab, drivetrain, type of hitch setup and more.

Below are a few terms to learn and remember when looking at your vehicle’s trailering guide.

Basic Curb Weight

This is the weight of your vehicle including all of the necessary liquids such as brake, power steering, transmission fluid and anything else the vehicle needs in order to run properly. This weight does not include any passengers or cargo.

GVW (Gross Vehicle Weight)

The Gross Vehicle Weight is the current weight of the vehicle. This is an ever-changing number, due to the fact that life happens! Constant packing, unpacking, extra passengers and more always change the GVW. If you’ve driven down the highway and noticed a weigh station for large trucks and semis, this is the number they’re weighing for.

GVWR (Gross Vehicle Weight Rating)

The Gross Vehicle Weight Rating is given by the manufacturer of the vehicle, and will never change. It is the maximum amount of weight you can carry in your vehicle. It is extremely important to know this number. If the Gross Vehicle Weight exceeds the Gross Vehicle Weight Rating, it is possible to run into many issues that can include an engine overload or other mechanical issues.

GCWR (Gross Combination Weight Rating)

The Gross Combination Weight Rating is a combination weight of both the GVW with passengers and cargo, plus the weight of the loaded trailer.

Tongue Weight

The Tongue Weight (also known as the Vertical Tow Rate) is the amount of weight the trailer is putting on the tow hitch. Depending on your hitch, this weight can be spread in order to ensure that there is not too much weight being put on the hitch. Hitches have different classes depending on the weight you’re looking to tow.

Choose the Right Equipment

Having the right equipment when you are towing is crucial to safely getting the job done. Ensure your vehicle is correctly equipped to tow, with receiver hitch attached to the tow vehicle. When attaching the hitch to the trailer, you’ll need a trailer ball. These can either come already attached to the ball mount or hitch tongue, or are a separate piece. A trailer ball makes it easy to maneuver around and ensure the trailer is level. Of course, make sure the ball mount is compatible with the trailer, hitch, and the weight being placed on it.

Our Parts Specialists here at Speck Buick GMC know what you need. We are more than happy to figure out what size and class of hitch and mount you’ll need in order to get the job done.

Get Connected

In order to prevent any accidents, making sure your trailer brake and lights are connected to your vehicle are important. If you brake suddenly and the person behind you can’t tell, that could cause an avoidable collision. Learn where your connections are, and where they hook up at. You can find a lot of this information in the owner’s manuals of your vehicle and trailer.

Drive Slow

It’s important to understand that your vehicle is carrying extra weight, and not only can it strain the engine, but the connection from trailer to vehicle. While towing, ensure you take corners carefully, and don’t go any faster than necessary. Ensure that you are creeping to a stop, and avoid any sudden braking. Extra caution should be practiced on hills, as these are tricky when towing. Like mentioned, drive slow – and don’t be afraid to use your hazards to let other driver’s know that you’re going to be going at a slower speed. When descending, shifting down can make it easier on your engine.

If you’d like to learn more about towing with your GMC, our experts are more than happy to help!

When purchasing a truck or vehicle intended to tow, haul, or go off-road, the engine picked will be the engine that can successfully do the job. But what about during everyday driving? Full power from your large engine 100% can cause unnecessary wear and a loss of precious fuel economy.

That is why GM created the Active Fuel Management and Dynamic Fuel Management systems. Active Fuel Management and Dynamic Fuel Management are engine systems GM has implemented for better fuel efficiency without sacrificing horsepower or torque.

Active Fuel Management

When you’re driving at cruising speeds or in conditions where your engine is not utilizing all power, the Active Fuel Management comes into play. This system detects when your engine does not need full power and will stop fuel delivery to half the cylinders, 3 on a V6 engine and 4 on a V8 engine. A solenoid system will then deactivate those cylinders to decrease power used and, according to GM authority, improve fuel economy by up to 12 percent. The Active Fuel Management system performs quietly and seamlessly so you won’t even know it’s happening.

Dynamic Fuel Management

The Dynamic Fuel Management system takes a step up from Active Fuel Management and adds the advancement of technology with a DFM computer that makes quick calculations that determine how many — and which — cylinders need to be deactivated to perform at optimum levels. This sophisticated system can make this determination 80 times a second and operates with 17 different cylinder patterns (GM Authority). This technology is an industry-first and can be found in new vehicles, such as the 2021 Sierra 1500.

Both of these great technological automotive advancements have given consumers less time at the pump and more time on the road — ask our experts here at Speck Buick GMC of Tri-Cities how you can keep your big engine and save your fuel with these systems today.
