Four-Wheel-Drive Light

For vehicles equipped with the four-wheel-drive light, it comes on when a vehicle with a manual transfer case is shifted into four-wheel drive and the front axle engages.
Some delay between the shifting and the light coming on is normal.
See Four-Wheel Drive on page 9‑43 for more information.
