If No Steam Is Coming from the Engine Compartment
If an engine overheat warning is displayed but no steam can be seen or heard, the problem might not be too serious. Sometimes the engine can get a little too hot when the vehicle:
• Climbs a long hill on a hot day.
• Stops after high-speed driving.
• Idles for long periods in traffic.
• Tows a trailer.
If the overheat warning displays with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest fan speed. Open the windows as necessary.
3. In heavy traffic, let the engine idle in N (Neutral) while stopped.
If it is safe to do so, pull off the road, shift to P (Park) or N (Neutral), and let the engine idle.
