Notice: We recommend you use only fluid labeled DEXRON®-III, because fluid with that label is made especially for your automatic transaxle. Damage caused by fluid other than DEXRON®-III is not covered by your new vehicle warranty. 3. After adding fluid, recheck the fluid level as described under "How to Check" listed previously in this section. 4. When the correct fluid level is obtained, push the dipstick back in all the way. 3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the cross-hatched area. 4. If the fluid level is in the acceptable range, push the dipstick back in all the way. Engine Coolant The cooling system in your vehicle is filled with DEX-COOL® engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOL® extended life coolant. The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating or if you need to add coolant to your radiator, see Engine Overheating on page 5-29. How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transaxle fluid to use. See Part D: Recommended Fluids and Lubricants on page 6-16. 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 doesn't take much fluid, generally less than one pint (0.5 L). Don't overfill. 5-26
