Step 1: Understand Your Vehicle’s Current Drivetrain Mode
Before making any changes, it’s important to confirm which drivetrain mode your vehicle is currently in. Most GMC vehicles, like the GMC Terrain, automatically engage AWD when needed, so you might not need to switch anything. However, if you’re driving a model such as the Sierra 1500 or Sierra 2500, you may have a manual 4WD system that requires a bit more attention.
- AWD Mode: If your vehicle is in AWD mode, power is being sent to all four wheels automatically. You might not need to do anything unless you want to manually switch to 2WD or change driving modes.
- 4WD Mode: If you’re using 4WD, you will likely be in either 2WD or 4WD High, and you may need to manually engage the system for rough conditions or off-roading.
If you’re unsure of which mode you’re in, consult your vehicle’s dashboard display or the GM drive mode switch.
Step 2: Switching to AWD in Your GMC Vehicle
For vehicles equipped with AWD, such as the GMC Terrain, the system generally engages automatically when conditions call for it, like in light rain or snow. However, in some models, like the GMC Acadia or the Sierra 1500, you can manually switch between AWD and 2WD, thanks to the GM drive mode switch. Here’s how to manually activate AWD:
- Locate the GM Drive Mode Switch: This is usually a dial or button on the center console or dashboard, depending on your vehicle model.
- Turn the Dial to AWD: Rotate the dial or press the button to engage AWD. In most cases, the vehicle will automatically sense when extra traction is needed and distribute power to all four wheels.
While driving in AWD, your vehicle will automatically adjust power between the wheels depending on road conditions. This is especially helpful on wet or slippery roads, giving you added stability and traction.
Step 3: Switching to 4WD in Your GMC Vehicle
For models with 4WD, such as the GMC Sierra 2500, switching between 2WD and 4WD requires a few more steps. These vehicles give you more control over your drivetrain, allowing you to engage 4WD when conditions require extra traction. Follow these steps to switch into 4WD:
