window as necessary.
3. Try to keep your engine under load (in a drive gear where the engine
runs slower).
If you no longer have the overheat warning, you can drive. Just to be safe,
drive slower
for about ten minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your vehicle right
away.
If there’s still no sign of steam, you can idle the engine for two or three
minutes while you’re parked, to see
if the warning stops. But then, if you
still have the warning, TURN
OFF THE ENGINE AND GET
EVERYONE OUT OF THE VEHICLE until it cools down.
You may decide not to lift the hood but to get service help right away.
