ENGINE COOLING FAN WARNING

Maintain coolant concentration within 48% to 50%, which equates to a freeze point between -30°F (-34°C) and -34°F (-37°C). Coolant concentration should be checked using a refractometer. We do not recommend the use of hydrometers or coolant test strips for measuring coolant concentration. Adding Coolant WARNING Never remove the coolant reservoir cap when the engine is running or hot. Note: Automotive fluids are not interchangeable. Do not use coolant or windshield washer fluid outside of its specified function and vehicle location. Note: Do not use stop leak pellets, cooling system sealants, or non-specified additives as they can cause damage to the engine cooling or heating systems. Resulting component damagemay not be covered by the vehicle Warranty. It is very important to use prediluted coolant approved to the correct specification in order to avoid plugging the small passageways in the engine cooling system. See Capacities and Specifications (page 250). Do not mix different colors or types of coolant in your vehicle. Mixing of engine coolants or using an incorrect coolant may harm the engine or cooling system components and may not be covered by the vehicle Warranty. Note: If prediluted coolant is not available, use the approved concentrated coolant diluting it to 50/50with distilledwater. See CapacitiesandSpecifications (page 250). Using water that has not been deionised may contribute to deposit formation, corrosion and plugging of the small cooling system passageways.

Keep your hands and clothing clear of the engine cooling fan.

Under certain conditions, the engine cooling fanmay continue to run for several minutes after you switch your vehicle off. ENGINE COOLANT CHECK WARNINGS Do not add engine coolant when the engine is hot. Steam and scalding liquids released from a hot cooling system can burn you badly. Also, spilling coolant on hot engine parts can burn you. Do not put engine coolant in the windshield washer fluid container. If sprayed on the windshield, engine coolant could make it difficult to see through the windshield. To reduce the risk of personal injury, make sure the engine is cool before unscrewing the coolant pressure relief cap. The cooling system is under pressure. Steam and hot liquid can come out forcefully when you loosen the cap slightly. Do not add coolant further than the MAX mark. When the engine is cold, check the concentration and level of the coolant at the intervals listed in the scheduled maintenance information. See Scheduled Maintenance (page 396). Note: Make sure that the coolant level is between the MIN and MAX marks on the coolant reservoir. Note: Coolant expands when it is hot. The level may extend beyond the MAX mark.
