How to Add Fluid Refer t o the Maintenance Schedule to determine what kind of transmission fluid to use. See "Recommended Fluids and Lubricants" in the Index. Add tluid only after checking the transmission fluid HOT. (A COLD check is used only as a reference.) If the fluid level is low, add only enough of the proper fluid to bring the level up to the HOT area for a hot check. It doesn't take much fluid, generally less than a pint (0.5 L). DOLJ overfill. We recommend you use only 't fluid labeled DEXRON@-111,because fluid with that label is made especially foryour automatic transmission. Damage caused by fluid other than DEXRON-111 is not covered by your new vehicle warranty. After adding fluid, recheck the fluid level as described under "How to Check." When the correct fluid level is obtained, push the dipstick back in a l l the way; then flip the handle down to lock the dipstick in place. Rear Axle When to Check and Change Lubricant Refer to the Maintenance Schedule to determinehow often to check the lubricant and when to change it. See "Scheduled Maintenance Services" in the Index.
