Notice: If your engine catches fire because you keep driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty. See "Overheated Engine Protection Operating Mode" in the Index for information on driving to a safe place in an emergency. If you get the overheat warning with no sign of steam, try this for a minute or so: 1. If your air conditioner is on, turn it off. 2. Turn on your heater to full hot at the highest fan speed and open the window as necessary.

Climb a long hill on a hot day. Stop after high-speed driving. 0 3. If you're in a traffic jam, shift to NEUTRAL (N); otherwise, shift to the highest gear while driving - AUTOMATIC OVERDRIVE (D).

If the warning continues, pull over, stop, and park your vehicle right away. If there's still no sign of steam, idle the engine for three minutes while you're parked. If you still have the warning, turn off the engine and get everyone out of the vehicle until it cools down. Also, see "Overheated Engine Protection Operating Mode" listed previously in this section.
