Note: A four-wheel drive vehicle has two differentials, each located in the center of its respective axle. On a two-wheel drive vehicle, there is a single differential located in the center of the rear axle. When servicing a four-wheel drive vehicle, it is necessary to check the level in both differentials.
1. On all front differentials and most rear differentials, the filler hole is closed with a metal screw plug. To check the level, you must remove the plug. To get to it, you need to lift the car and support it securely. It is prohibited to stand under a vehicle supported only by a jack. During the test, the car must be level, otherwise the level will be displayed with a significant error.
2. Unscrew the plug from the filler hole located in the differential housing or cover (see illustrations).
16.2a. To check the differential oil level, remove the rear axle filler plug (A). Some models have a transmission oil specification plate (IN)
16.2b. To check the differential oil level (four-wheel drive), remove the filler plug (A). Drain plug (IN) also located on the casing
3. The level should be at the bottom edge of the filler hole. The level in the rear differential filled with synthetic oil should be 12 mm below the edge of the filler hole. If necessary, squeeze the bottle or use a pump to add oil until it begins to flow out of the filler hole. On some models, there is a label next to the plug that provides information regarding differential fluid.
4. Install and tighten the plug securely.
