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.

A CAUTION:
You can be burned if you spill coolant on hot engine parts.
Coolant contains ethylene glycol and
it will burn if the engine
parts are hot enough. Don’t spill coolant on
a hot engine.
Should a low coolant condition
exist, an overheat protection “Limp
Home” feature of the
4.6L Northstar allows alternate firing groups of
four cylinders for a predetermined number of cycles to prevent engine
damage, enabling your vehicle
to be driven to the nearest service center.

COMPACT SPARE TIRE
Although the compact spare was fully inflated when your vehicle was
new,
it can lose air after a time. Check the inflation pressure regularly. It
should be 60 psi (420 kPa). The compact spare is made to go up to 3,000
miles (5000 km), so you can finish your trip and have your full-size tire
repaired or replaced where you want. Of course, it’s best
to replace your
spare
with a full-size tire as soon as you can. Your spare will last longer
and be
in good shape in case you need it again.
Your anti-lock brake system warning li.ght
may come on when you are
driving
with a compact spare. See “Anti-Lock Brake System Warning
Light” in the Index.
