driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be

If No Steam Is Coming From Your Engine
If you get the overheat
warning
but see or hear
no
steam, the problem may not be too
serious.
Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow
a
trailer.
If
you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If
you're in a traffic jam, shift
to
NEUTRAL (N);
otherwise, shift to the highest gear while
driving
--
AUTOMATIC OVERDRIVE (D)
or
THIRD
(3).
If you no longer have the overheat warning, you
can
drive.
Just to
be safe, drive slower
for about
10
minutes. If the warning doesn't come back on, you
can drive normally.
If the warning continues, pull
over, stop, and par? ;
~
~
r
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
oflthe engine
and
get everyone out o f the vehicle until it
cools down.
Also,
see "Overheated Engine Protection
Operating Mode" listed previously in this section.
You may decide not to lift the hood but to get service
