324 MAINTAINING YOUR VEHICLE To minimize the possibility of catalyst damage: • Do not shut off the engine or interrupt the ignition when the transaxle is in gear and the vehicle is in motion. • Do not try to start the engine by pushing or towing the vehicle. • Do not idle the engine with any spark plug wires disconnected for prolonged period. COOLING SYSTEM WARNING! (Continued) • You or others can be badly burned by hot engine coolant (antifreeze) or steam from your radiator. If you see or hear steam coming from under the hood, do not open the hood until the radiator has had time to cool. Never try to open a cooling system pressure cap when the radiator is hot. Coolant Checks Check engine coolant (antifreeze) protection every 12 months (before the onset of freezing weather, where applicable). If the engine coolant (antifreeze) is dirty or rusty in appearance, the system should be drained, flushed and refilled with fresh engine coolant (antifreeze). Check the front of the A/C condenser for any accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from a garden hose vertically down the face of the condenser. WARNING! • When working near the radiator cooling fan, disconnect the fan motor lead or turn the ignition switch to the OFF position. The fan is temperature controlled and can start at any time the ignition switch is in the ON position. (Continued)
