Which pickup can challenge the 2023 Sierra 1500? Have you recently checked this latest model? Ain’t this a beast-like vehicle? A four-wheel truck is advantageous in every condition or on any difficult surface, including slippery roads, muddy pathways, snowy rural areas, or uneven gravel driveways. But how to engage 4 wheel drive GMC Sierra?
By using the 4-wheel shift lever, the GMC Sierra 4 Wheel generally has the capacity to manually engage it. Therefore, the GMC Sierra 4WD system must be turned on from the driver’s seat, though.
You can simply pick from 4 different modes to drive the vehicle. Plus, this article will try to deliver some system understanding of 4-wheel so that your next journey becomes much more convenient while you drive.

How to Engage 4 Wheel Drive GMC Sierra – 4 Different Modes to Use
The GMC Sierra Drive’s 4 wheels send an equal amount of power to each one, making it more efficient on difficult terrain than a 2-wheel vehicle. Also, a four-wheel drive gives significant control because it has a bit more traction than a two-wheel drive. Anyway, we want to address all of the vehicle’s modes so that you can choose what feels right and understand how to activate four-wheel drive.
Mode 1: 2-Wheel Drive
When it comes to the 2023 GMC Sierra 1500 Truck, the 2-wheel drive mode is a standard one but you have 4-wheel drive as well. Any smooth, flat, or paved roads do not require four wheels to be used for navigation.
In this system, the transferring case is given power before the rear axles and wheels receive it. As there is little chance of car damage on smooth roads, this default driving mode is one that we typically choose.
Mode 2: High 4-Wheel Drive
Here comes the use of four-wheel drive on slippery or soft surfaces, such as icy or muddy ones. Why do we use high-range, “4-wheel” trucks? Here, the transferring case distributes power to the front and rear axles along with all four wheels after engaging the front axle. There is a possibility of encountering the condition known as “crow hop,” which refers to tiny mismatches in tire size with track length that lead to problems on high-friction terrain.
This model is built with a transfer case that can be switched on the fly to make shifting from a 4 to 2-wheel drive simple. However, bear in mind that the increased 4-wheel drive mode is extremely inappropriate for flat roads with good traction.
Mode 3: Low 4-Wheel Drive
Engaging 4WD or 4↓ improves your car’s traction on the roadway in low-traction situations, particularly for fast-changing lanes on wet roads and secure footing in muddy areas. The torque transmitted to the wheels is massively increased and almost doubles when in low range.
Whenever we get stuck in the mud, sand, or icy grounds, we switch to this wheel drive mode to transfer power to the wheels. Turn on this option, particularly for off-road driving, and keep your speed under 45 mph.
In this mode, the drivers must put the transmission in neutral to disconnect the torque and enable gear shifting by the transfer case. You could find that the manual 4-wheel drive on your 1992 GMC Sierra won’t engage. Basically, it happens if the front differential is not engaging, therefore check the solenoid.
However, it’s beneficial in Manual Shift Transfer cases to keep the car going at less than 3 to 5 mph while changing into 4 to let the gears’ teeth line up. Remember, you should stay away from the dry roadside.
Automatic 4-Wheel Drive
Another mode we use to switch wheel drive to four-wheel drive is 4WD Auto Mode. The Sierra RWD GMC can simply change from auto 2-wheel drive to auto 4-wheel drive. When choosing between a smooth path and a difficult road, choose the setting.
Generally, the front axle is engaged with “auto” or the automatic 4×4 mode. However, in regular condition, the transfer case directs most of the vehicle’s power to the back wheels and clutches and adjusts the front torque to increase traction plus offer stability.
How Does 4-Wheel GMC Sierra Perform?
We already talked about the engaging facts but still, we would like to mention the major points about the way GMC 4 Wheel operates. Let’s check out.
- The transfer case generally power supplies to the front axle, rear axles, and four wheels after the front axle is engaged.
- The transfer case on the GMC Sierra 4WD may switch between high-range and low-range gears.
- Pick from Two-High, Four-High, or Four-Low modes.
- Ensure the knob and the GMC Sierra 4WD system are activated.
- Remember that low-range mode has a larger gear ratio than high-range mode.

Frequently Asked Questions
1. How do I turn on a 4-wheel drive?
You can easily turn the four-wheel drive just by following the three steps:
a). Just press the lock button on the remote control once, and then double-click.
b). Open the door, then push the start button on the dash or, if you’re driving, sit in the seat, press the brake, then push the “ start ” button.
c). Turn the knob 1 click to the right to engage 4WD after powering the vehicle on, or 2 clicks to enter 4-low by pressing the brake, shifting to neutral, then turning the knob 1 click to the right.
2. What happens if you drive a car with 4WD engaged?
When you are on the highway road, the car can still accelerate plus decelerate if the front wheels start to slide and if it’s operated by the rear wheels. Additionally, when activated at highway speeds on dry pavement, 4-wheel drive systems will potentially wear out quickly.
3. What is the best pickup 4-wheel drive car GMC or Ford F-150?
In terms of performance, the F150 outperforms the GMC Sierra. This is to say that you should avoid the 4WD because it adds a lot of difficulty and expense. Therefore, 2WD with a limited-slip or Detroit locker differential and the ideal tires will perform almost the same. Possibly you’ll need to pack a winch with a lot of cables if you must drive along a serious roadside.
4. Do you have to be neutral to engage 4WD?
When the car is completely stopped, some 4-wheel modes can be engaged manually or with the transmission in Park or Neutral. After getting some power in another gear, you can also ride into neutral.
