Sometimes the engine canget 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.If you get the overheat warning with no sign of steam,try this for a minute or so:1. In heavy traffic, let the engine idle in NEUTRAL (N)while stopped. If it safe to do so, pull of the road,shift to PARK (P) or NEUTRAL (N) and let theengine idle.2. Set the temperature control to the highest heatsetting and open the windows, as necessary.If you no longer have the overheat warning, you candrive. Just to be safe, drive slower for about 10 minutes.If the warning does not come back on, you can drivenormally.If the warning continues, pull over, stop, and park yourvehicle right away.If there is still no sign of steam, idle the engine forthree minutes while you are parked. If you still have thewarning, turn off the engine and get everyone out ofthe vehicle until it cools down.
