It is recommended to change the oil on a warmed-up transfer case. It is better to plan an oil change after a long trip. We clean the transfer case housing around the drain hole. Place a container with a capacity of at least 1.0 l under the drain hole.

Using a 12 mm Allen key, unscrew the drain plug...

... and drain the oil into a container provided.
We clean the plug magnet and screw the plug back into place.
Fill the transfer case with transmission oil to the required level (see "Checking the oil level in the transfer case").
