If you get the overheat warning with no sign of steam, try this for aminute or so: 1. Turn off your air conditioner. 2. Turn on your heater to full hot at the highest fan speed and open the window as necessary. 3. If you're in a traffic jam, shift to "N" (Neutral). If you no longer have the overheat warning, you can drive. Just tobe safe, drive slower for about ten minutes. If the warning doesn't come back on, you can drive normally. If the warning continues, pull over, stop, and park your vehicle right away. If there's still no sign of steam, you can idle the engine for two orthree minutes while you're parked, to see if the warning stops. But then, if you still have the warning, TURN OFF THE ENGINE AND GET EVERYONE OUT OF THE VEHICLE until it cools down. When you decide it's safe to lift the hood, here's what you'll see: Coolant recovery tank Radiator pressure cap 0 Electric engine fans You may decide not to lift the hood but to get service help right away. 208
