Nickel Metal Hydride Battery Replacement
CONSULT-II contains a nickel metal hydride battery. When replacing the battery obey the following:
WARNING:
Replace the nickel metal hydride battery with Genuine CONSULT-II battery only. Use of another bat-
tery may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard
if mistreated. Do not recharge, disassemble or dispose of in fire.
Keep the battery out of reach of children and discard used battery conforming to the local regula-
tions.

Control Operation
AUTO SWITCH
The compressor, air intake doors, air mix door, mode doors, and blower speed are automatically controlled
so that the in-vehicle temperature will reach, and be maintained at the set temperature selected by the
operator.
The air conditioning cooling function operates only when the engine is running.
ECON SWITCH
Fully automatic control with the compressor off. With the compressor off, the system will not remove heat
(cool) or de-humidify. The system will maintain the in-vehicle temperature at the set temperature when the
set temperature is above the ambient (outside) temperature.
TEMPERATURE SWITCH (Potentio Temperature Control)
Increases or decreases the set temperature.
OFF SWITCH
The compressor and blower are off, the air intake doors are set to the outside air position. Then, the mode
doors are set to the foot (80% foot and 20% defrost) position. In the off position, the A/C system uses the
vehicle's ªflow throughº ventilation. It tries to maintain the interior temperature based on the last set tem-
perature of the system.
FAN SWITCH
Manual control of the blower speed. Four speeds are available for manual control (as shown on the display
screen):
low
, medium low, medium high, high
MODE SWITCH
Manual control of the air discharge outlets. Four selections are available (as shown on the display screen):
face
, bi-level, foot, defrost/foot
