Maintenance

To top up the coolant level do the following: 1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap. 2. Add prediluted coolant meeting the correct specification. See Capacities and Specifications (page 312). 3. Add enough prediluted coolant to reach the correct level. 4. Replace the coolant reservoir cap, turn it clockwise until you feel a strong resistance. 5. Check the coolant level in the coolant reservoir the next few times you drive your vehicle. Note: During normal vehicle operation, the coolant may change color from orange to pink or light red. As long as the coolant is clear and uncontaminated, this color change does not indicate the coolant has degraded nor does it require the coolant to be drained, the system to be flushed, or the coolant to be replaced. Do not mix different colors or types of prediluted coolant in your vehicle. Mixing of prediluted coolant or using an incorrect prediluted coolant may harm the engine or cooling system components and may not be covered by the vehicle Warranty. In case of emergency, you can add a large amount of water without engine coolant in order to reach a vehicle service location. In this instance, qualified personnel: 1. Must drain the cooling system. 2. Chemically clean the cooling system. 3. Refill with prediluted coolant as soon as possible. Water alone, without prediluted coolant, can cause engine damage from corrosion, overheating or freezing.

Do not use the following as a coolant substitute: • Alcohol. • Methanol. • Brine. • Any coolant mixed with alcohol or methanol antifreeze. Alcohol and other liquids can cause engine damage from overheating or freezing. Do not add extra inhibitors or additives to the coolant. These can be harmful and compromise the corrosion protection of the coolant. Recycled Coolant We do not recommend the use of recycled coolant as an approved recycling process is not yet available. Dispose of used engine coolant in an appropriate manner. Follow your community's regulations and standards for recycling and disposing of automotive fluids. Severe Climates If you drive in extremely cold climates: • It may be necessary to increase the coolant concentration above 50%. • A coolant concentration of 60% provides improved freeze point protection. Coolant concentrations above 60% decrease the overheat protection characteristics of the coolant and may cause engine damage.
