1. Safely pull to the side of the road.
Put the transmission in Neutral or

system and all other accessories.
Turn on the hazard warning
indicators.

coming from under the hood, turn
off the engine.

Taking Care of the Unexpected
3. If you do not see steam or spray,
leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading
(climbing a long, steep hill on a
hot day with the A/C running, for
example), the engine should start
to cool down almost immediately.
If it does, wait until the tempera-
ture gauge comes down to the mid-
point then continue driving.
4. If the temperature gauge stays at
the red mark, turn off the engine.
5. Wait until you see no more signs
of steam or spray, then open the
hood.
6. Look for any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you
continue driving (see
Emergency
on page 283 ).
Towing
7. If you don't find an obvious leak,
check the coolant level in the
radiator reserve tank (see page
161 ). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks.
