MAINTAINING YOUR VEHICLE 419 CAUTION! • Mixing of engine coolant (antifreeze) other than the specified HOAT engine coolant (antifreeze) may result in decreased corrosion protection and engine damage. If a non-HOAT engine coolant (antifreeze) is introduced into the cooling system in an emergency, it should be replaced with the specified engine coolant (antifreeze) as soon as possible. • Do not use water alone or alcohol based engine coolant (antifreeze) products. Do not use additional rust inhibitors or antirust products, as they may not be compatible with the engine coolant (antifreeze) and may plug the radiator. (Continued) CAUTION! (Continued) • This vehicle has not been designed for use with propylene glycol based engine coolant (antifreeze). Use of propylene glycol based engine coolant (antifreeze) is not recommended. Adding Coolant Your vehicle has been built with an improved engine coolant (antifreeze) that allows extended maintenance intervals. This engine coolant (antifreeze) can be used up to five years or 102,000 miles (170 000 km) before replacement. To prevent reducing this extended maintenance period, it is important that you use the same engine coolant (antifreeze) throughout the life of your vehicle. 7
