Vehicle Service and Care Notice: If the air cleaner/filter is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner/filter in place when you are driving. Notice: Use of the incorrect automatic transmission fluid may damage your vehicle, and the damages may not be covered by your warranty. Always use the automatic transmission fluid listed in Recommended Fluids and Lubricants on page 11-12. 9-13 A 50/50 mixture of clean, drinkable water and DEX-COOL® coolant will: • Give freezing protection down to −34°F (−37°C). 265°F (129°C). • Give boiling protection up to • Protect against rust and corrosion. Automatic Transmission Fluid It is not necessary to check the transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take your vehicle to a dealer/retailer and have it repaired as soon as possible. Change the fluid and filter at the intervals listed in the Maintenance Schedule. See Scheduled Maintenance on page 11-4. Be sure to use the transmission fluid listed in Recommended Fluids and Lubricants on page 11-12. 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 five 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, see Engine Overheating on page 9-16. • Help keep the proper engine temperature. • Let the warning lights and gages work as they should. Notice: Using coolant other than DEX-COOL® can cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant may require changing sooner, at the first maintenance service after each 30,000 miles (50 000 km) or 24 months, whichever occurs first. Any repairs would not be covered by the vehicle warranty. Always use DEX-COOL® (silicate-free) coolant in the vehicle.
