Before Engaging 4WD:
1. Vehicle Speed: Bring the vehicle to a complete stop before shifting into 4WD. Driving at any speed while shifting into 4WD can cause damage to the drivetrain.
2. Surface Conditions: Only engage 4WD when necessary. Driving in 4WD on dry pavement can cause premature wear and tear on the drivetrain components, especially at higher speeds.
Engaging 4WD:
1. Transfer Case Lever: Locate the transfer case lever. It's usually located on the floor console, near the gear shift lever. It's a lever that has positions for 2WD (2-High), 4WD High (4-High), and Neutral. Sometimes there's also a 4-Low position but not all models had this.
2. Shift to 4-High: To engage 4-wheel drive high, carefully move the transfer case lever to the 4-High position. You'll hear a slight clunk as the system engages.
Important Considerations:
* 4-Low (if equipped): If your Blazer has a 4-Low position, use it only for very low speeds and extreme off-road conditions such as steep inclines or deep mud or snow. Driving in 4-Low on paved roads will damage your drivetrain.
* Driving in 4WD: Avoid sharp turns and sudden acceleration or braking while in 4WD, particularly on dry pavement.
* Disengaging 4WD: Once you're back on a dry, grippy surface, shift the transfer case lever back to the 2WD (2-High) position. Again, do this while the vehicle is at a complete stop.
* Owner's Manual: The most accurate and detailed instructions are found in your vehicle's owner's manual. Refer to it for specific details and illustrations.
If you are unsure about any aspect of engaging your 4WD system, it is always best to consult a qualified mechanic. Improper use can cause significant damage to your vehicle's drivetrain.
