10-18 Vehicle Care The temperature gauge indicates an overheat condition exists. Driving extended distances and/or towing a trailer in the overheat protection mode should be avoided. If there is no sign of steam, idle the engine for three minutes while parked. If the warning is still displayed, turn off the engine until it cools down. Also, see "Overheated Engine Protection Operating Mode" next in this section. Power Steering Fluid { Caution After driving in the overheated engine protection operating mode, the engine oil will be severely degraded. Any repairs performed before the engine is cool may cause engine damage. Allow the engine to cool before attempting any repair. Repair the cause of coolant loss, change the oil, and reset the oil life system. See Engine Oil on page 10-7. The power steering fluid reservoir is under the engine cover on the passenger side of the vehicle. See Engine Compartment Overview on page 10-5 for reservoir location. Overheated Engine Protection Operating Mode This emergency operating mode lets the vehicle be driven to a safe place in an emergency situation. If an overheated engine condition exists, an overheat protection mode which alternates firing groups of cylinders helps prevent engine damage. In this mode, there is a significant loss in power and engine performance. When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.
