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 on page 380 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 the air conditioner is on, turn it off. 2. Turn on the heater to full hot at the highest fan speed and open the windows as necessary. 3. If you are in a traffic jam, shift to NEUTRAL (N); otherwise, shift to the highest gear while driving - DRIVE (D). If the vehicle no longer has the overheat warning, you can drive. Just to be safe, drive slower for about 10 minutes. If the warning does not come back on, you can drive normally. If No Steam Is Coming From Your Engine If you get an engine overheat warning but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you: • Climb a long hill on a hot day. • Stop after high-speed driving. • Idle for long periods in traffic. • Tow a trailer. 379
