Vehicle Care If the warning continues, pull over, stop, and park the vehicle right away. 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 on page 10-23. The engine coolant temperature warning light comes on the instrument panel, to indicate the vehicle has entered overheated engine protection operating mode. The temperature gauge also indicates an overheat condition exists. Driving extended distances and/or towing a trailer in the overheat protection mode should be avoided. 10-23 Power Steering Fluid (3.6L V6 Engine with AWD) Overheated Engine Protection Operating Mode This emergency operating mode allows the vehicle to 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 significant loss in power and engine performance. Power Steering Fluid (2.4L L4 Engine and 3.6L V6 Engine with FWD) The vehicle has electric power steering and does not use power steering fluid. See Engine Compartment Overview on page 10-6 for information on the location of the power steering fluid reservoir. When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless a leak is suspected in the system or an unusual noise is heard. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.
