message comes on with no sign of
steam, try this for a minute or so:
1. 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.
2. Turn on the heater to full hot at
the highest fan speed and open
the window as necessary.
If the vehicle no longer has the
overheat warning, the vehicle can
be driven. Just to be safe, drive
slower for about 10 minutes. If the
warning does not come back on,
drive normally.
If the warning continues, pull over,
stop, and park the vehicle
right away.
If there is still no sign of steam and
the vehicle is equipped with an
engine driven cooling fan, push
down the accelerator until the
engine speed is about twice as fast
as normal idle speed for at least
five minutes while the vehicle is
parked. If the warning is still there,
turn off the engine and get everyone
out of the vehicle until it cools down.
The decision may be made not to lift
the hood, but to get service help
right away.
