gauge and a warning light on the
instrument panel cluster that
indicate an overheated engine
condition. See Engine Coolant
Temperature Gauge

You may decide not to lift the hood
when this warning appears, but
instead get service help right away.
See Roadside Assistance Program
on page 126
.
If you do decide to lift the hood,
make sure the vehicle is parked on
a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fan(s)

running the engine without
coolant is not covered by the
warranty.
