Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves into the red warning zone,
your engine is hot. To prevent engine overheating, the
air conditioning compressor will
turn off automatically,
a fdst-pulsed chime
will sound, and the message
ENGINE
HOT ... A/C OFF will appear in the information
center.
As the engine cools down, the air conditioning
compressor will automatically turn back on.
If the coolant temperature is over 26 1 OF (127”C), the
message
HOT ... STOP ENGINE will appear. It means
that your engine coolant has overheated.
If you have
been operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
In “Problems on the Road,’? this manual shows what to
do. See “Engine Overheating”
in the Index.
If your coolant level is low, the message LOW ENGINE
COOLANT will appear 011 the Driver Information
Center. Check your coolant level as soon
as possible.

AUTO-PUSH: To allow the system to automatically
control
the temperature, air distribution and Fdn speed:
1. Set the temperature you want with the colored
temperature buttons.
2. Press the AUTO-PUSH switch. The AUTO light will
appear below the selector.
To maintain proper comfort, the air flow direction
will
automatically change with increases or decreases in
outside temperature, interior temperature, or sun load.
After starting a cold engine, there may be up to a
four-minute delay before the fan is turned on. The fan
will automatically increase
in speed as the coolant
temperature rises.
AUTO FAN: Sets the fan speed. Turn this knob to the
right to raise
the fan speed, to the left to lower the fan
speed. The fan speed
will be displayed by the lights
around the knob (except
in the AUTO mode).
Use the following controls when you wish to override
the AUTO setting.
Directional Controls
When the AUTO-PUSH knob is pressed, the fan speed
will go
to AUTO unless you select a different speed.
After
you turn the knob to a directional control, the set
interior temperature
will be displayed for about five
seconds,
then the outside temperature will be displayed
"ri Upper: Directs air flow through the upper air
outlets
in the instrument panel.
f0 /I' Bi-Level: Use on cool, but sunny days. This
setting brings
in the outside air, but directs it in two
ways. The cool air is directed
to the upper portion of
your body through the instrument panel outlets, but most
warmed air is directed through the heater ducts and
a
little to the defrost and side window vents. At times, this
temperature difference may be more apparent than
others.

4. With the coolant surge tank pressure cap off', start the
engine and
let it run until YOLI can feel the upper r it d' lator
hose getting hot. Watch
out for the engine fans.
By this time, the coolant level inside the coolant surge
tank
may be lower. If the level is lower, add more of'the
proper mix
to the coolant surge tank until the level
reaches
FULL COLD.
5. Then replace the

The engine coolant
surge tank is located
on the driver’s side
of
the engine
compartment.

To Add Coolant
If you need more coolant, add the proper mix at the
surge tank, but only when the engine is cool.
When replacing the pressure cap, make sure it is tight.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
When you replace your thermostat, an AC@ thermostat
is recommended.
Power Steering Fluid
How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap
and wipe the dipstick with a clean rag. Replace the cap
and completely tighten it. Then remove the cap again
and look at the fluid level on the dipstick.
The level should be at the
FULL COLD mark. Add
enough fluid to bring the level up to the mark.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
