Air Conditioning
An automatic air conditioning has been adopted
in consideration to ease of use.

A clean air filter which removes pollen and
dust is included as a standard fitting for puri-
fying the air inside the cab.

Two air conditioning modes, A/C for eco-
nomical air conditioning and MAX for espe-
cially strong air conditioning, are provided.
Wireless Door Lock Remote Control System
With the wireless door lock remote control system, all the doors can be locked and unlocked by signals emitted
by the transmitter.
Power Window System
A power window system which enables all windows to be raised or lowered with switches has been adopted.
An auto up/down function and jam protection function have been added to the driver's power window.
HV Immobiliser System
HV immobiliser system will not allow the HV system to be started by duplicate key is used. This system
will permit the HV system to be started only when the ID code of the transponder chip impregnated in the
key matches the ID code registered beforehand in the transponder key amplifier.
Theft Deterrent System
When an attempt is made to forcibly enter the vehicle or open the hood or trunk lid without a key, or when
the battery terminals are removed and reconnected, this system sounds the horn and flashes the headlights,
taillights and emergency flashers for about 1 minute to alert the owner. At the same time, it locks all the
doors.
Storage Space
Ample storage space with an emphasis on practicality provided throughout the Prius.

CONVERTER
1. General
The power source for auxiliary equipment of the
vehicle such as the lights, audio system, and the air
conditioner cooling fan, as well as the ECUs, is
based on a 12 V system. Because the THS genera-
tor outputs at 273.6 V, the converter is used to
transform the voltage from DC273.6 V to DC 12
V in order to recharge the auxiliary battery. The
converter is installed on the underside of the in-
verter.
2. Operation

The DC273.6 V input is initially converted into alternating current by the transistor bridge circuit and
transformed into a low voltage by the transformer. After this, the current is rectified, smoothed (into direct
current) and converted into DC12 V.

The voltage at the positive terminal of the auxiliary battery is monitored by the converter and is maintained
at a constant level. Consequently, the voltage of the auxiliary battery is unrelated to the engine rpm (even
if the engine is stopped) and to the auxiliary equipment (output current of converter).

AIR CONDITIONING
DESCRIPTION
The air conditioning system in the Prius has the following features:
Both heating and demisting performances are realized by adopting performances are realized by adopting
the 2-way flow heater type air conditioning unit.
A multi-tank, super-slim structure evaporator has been adopted.
An automatic air conditioning system which provides enhanced air conditioning comfort according to the
occupant's senses has been adopted.
A semi-center location air conditioning unit, in which the evaporator and heater core are placed in the ve-
hicle's longitudinal direction, has been adopted.
A compact, high-performance scroll compressor with oil separator has been adopted.
The heat exchange efficiency has been improved through the adoption of the sub-cool condenser.
This condenser is integrated with the radiator to minimize the space they occupy in the engine compart-
ment.
A compact, lightweight, and highly efficient straight flow (full-path flow) aluminium heater core has been
adopted.
This heater core is integrated with a PTC (Positive Temperature Coefficient) heater, which excels in heat-
ing performance.
PTC heaters have been provided in the air duct at the footwell outlet in front of the air conditioning unit.
However, air conditioning without the PTC heaters is offered as an option on the U.S.A. models.
An electrical water pump with a bypass valve that provides a stable heater performance even if the engine
is stopped due to a function of the THS (TOYOTA Hybrid System) has been adopted.
A clean air filter that excels in removing pollen and dust is standard equipment.

Service Tip
The replacement interval for the clean air filter is 30,000 km or 2 years.
However, it varies with the use conditions (or environment). 164
5. Clean Air Filter
A clean air filter that excels in removing pollen and dust is standard equipment.
This filter, which cleans the air in the cabin, is made of polyester. Thus, it can be disposed of easily as a com-
bustible material, a feature that is provided in consideration of the environment.
To facilitate the replacement of the filter, a one-touch clip is used in the filter cover which is unified with filter
case. Thus, a construction that excels in serviceability has been realized.
