Maintenance and care • DO NOT MIX recycled coolant and conventional coolant together in your vehicle. Mixing of engine coolants may harm your engine's cooling system. • The use of an improper coolant may harm engine and cooling system components and may void the warranty of your vehicle's engine cooling system. If you are unsure which type of coolant your vehicle requires, contact your local dealer. Do not put engine coolant in the windshield washer fluid reservoir. If engine coolant is sprayed onto the windshield, it could make it difficult to see through the windshield. When the engine is cool, add a 50/50 mixture of engine coolant and distilled water to the engine coolant reservoir, until the coolant is at the "cold fill level" as listed in the engine coolant reservoir. • NEVER increase the coolant concentration above 60%. • NEVER decrease the coolant concentration below 40%. • Engine coolant concentrations above 60% or below 40% will decrease the freeze protection characteristics of the engine coolant and may cause engine damage. Plain water may be added in an emergency, but you must replace it with a 50/50 mixture of engine coolant and distilled water as soon as possible. Check the coolant level in the reservoir before you drive your vehicle the next few times (with the engine cool). If necessary, add a 50/50 mixture of engine coolant and distilled water to the engine coolant reservoir until the coolant level is at the "cold fill level" as listed on the reservoir. 146
