Manual Transfer Case
The transfer case shift lever is on the floor to the right of the driver.
Use this lever to shift into and out of Four-Wheel Drive.
A Four-Wheel Drive indicator light comes on when you shift into four-wheel drive and the front axle engages. See Four-Wheel-Drive Light on page 5‑29.
Some delay between shifting and when the indicator light comes on is normal.
