18 [IS15905( BCGV)05/96]The pointer moves from the C (cold) mark into
the normal band as your engine coolant warms
up. Under normal driving conditions, the pointer
should stay in the normal band. It is acceptable
for the pointer to fluctuate within the normal
band under normal driving conditions, and
under certain driving conditions such as, heavy
stop and go traffic, or driving up hills in hot
weather, for the pointer to indicate at the top of
the normal band.
[IS16005( BCGV)04/96]
If, under any circumstances, the pointer moves
above the normal band, the engine is
overheating and continued operation may cause
engine damage.

Engine Coolant Temperature Gauge
% [IS25112( GV)05/96]
one third page art:0010570-B
The engine coolant temperature gauge
[IS25114( GV)05/96]
This gauge indicates the engine coolant
temperature not the coolant level. If the coolant
is not at its proper level or mixture, the gauge
indication will not be accurate. It is identified by
a thermometer symbol, an ªHº (hot), and a ªCº
(cold). The ªNORMº indicates the normal
operating range. The bars will move into the
normal operating range as the engine coolant
warms up. It is acceptable under certain driving
conditions such as, heavy stop and go traffic, or
driving up hills in hot weather, for the gauge to
indicate at the top of the NORM band.
[IS25116( GV)05/96]
If, under any circumstance, the pointer moves
above the NORM band, the temperature symbol
flashes and a tone will sound to alert the driver
that the engine coolant is overheating and
continued operation may cause engine damage.

When in AUTOMATIC and weather conditions
require heat, air will be sent to the floor. But, a
feature is included in your EATC to prevent
blowing cold air to the floor if the engine
coolant is not warm enough to allow heating.
For a short time the fan will be at low speed
and air directed to the windshield. In 3-1/2
minutes or less, the fan speed will start to
increase and the airflow will change to the floor
area.

etc.), the six manual override buttons allow you
to select special air discharge locations. A
