Whether you’re using 4WD high or low, there are some practices that align with both types that you need to follow. When going from 2WD to 4WD high, unless you have to get out of the vehicle and manually enable it, you can usually switch between the two modes while in motion. However, if you need to go into 4WD low, make sure to come to a complete stop and allow the mode to fully transfer over before you start to slowly drive again.
Though you can tow with it, 4WD is mostly meant for rough terrains. This means you should not engage your 4WD while on standard dry pavement. You can damage your drivetrain. Additionally, 4WD does not assist with braking. You may find yourself in a turn and over-compensate in your braking, which can lead to an accident. It has also been proven that driving in 4WD makes drivers overconfident in their abilities, causing many to end up in a ditch. When using 4WD high or low for the first time, it’s best to check your owner’s manual for the correct operation procedure.
