How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transaxle fluid to use. See Recommended Fluids and Lubricants on page 420. If the fluid level is low, add only enough of the proper fluid to bring the level into the cross-hatched area on the dipstick. 1. Pull out the dipstick. 2. Using a long-neck funnel, add enough fluid at the dipstick hole to bring it to the proper level. It does not take much fluid, generally less than one pint (0.5 L). Do not overfill. Notice: Use of the incorrect automatic transaxle fluid may damage your vehicle, and the damages may not be covered by your warranty. Always use the automatic transaxle fluid listed in Recommended Fluids and Lubricants on page 420. 3. After adding fluid, recheck the fluid level as described under "How to Check Automatic Transaxle Fluid," earlier in this section. 4. When the correct fluid level is obtained, push the dipstick back in all the way. 322
