How to Add Automatic Transaxle Fluid Refer to the Maintenance Schedule to determine what kind of transaxle fluid to use. See Recommended Fluids and Lubricants on page 483. If the fluid level is low, add only enough of the proper fluid to bring the level into the crosshatched 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 483. 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. 360 Engine Coolant The cooling system in the vehicle is filled with DEX-COOL® engine coolant. This coolant is designed to remain in the vehicle for five years or 150,000 miles (240 000 km), whichever occurs first, if only DEX-COOL® extended life coolant is added. The following explains the cooling system and how to add coolant when it is low. If there is a problem with engine overheating or if coolant needs to be added to the radiator, see Engine Overheating on page 364. A 50/50 mixture of clean, drinkable water and DEX-COOL® engine coolant will: • Give freezing protection down to −34°F (−37°C). • Give boiling protection up to 265°F (129°C). • Protect against rust and corrosion. • Help keep the proper engine temperature. • Let the warning lights and gages work as they should.
