Air Inlet Control System
1) Manual Control
Drives the air inlet servomotor according to
the operation of the air inlet control switch and
fixes the dampers in the FRESH or RECIRC
position.
The 2-way flow mode control switches the re-
circulation / fresh-air function in accordance
with the opening of the air mix damper, calcu-
lates the target opening of the damper, and ro-
tates the servomotor.
2) Battery ECU Forced Fresh Air Mode
When the air conditioning ECU receives the forced fresh air mode signal from the battery ECU via the
HV ECU and the ECM, the damper forcefully switches to the FRESH mode.
3) DEF, FOOT / DEF Mode Control
When the mode switching switch is switched to FOOT / DEF mode from DEF mode or other than
FOOT / DEF mode, air conditioning ECU switches to FRESH mode forcibly.
Also, when the mode switching switch is switched to DEF mode from other than DEF mode, air condi-
tioning ECU turns MAX mode ON and switched to FRESH mode forcibly.
Compressor Control System
1) OFF Control
Turns OFF the magnetic clutch of the compressor when the conditions for turning the blower motor OFF
during warm-up control have been met.
2) Compressor Lock Judgment
When the magnetic clutch is ON, if the air
conditioning ECU judges that the compressor
has been locked, it turns OFF the magnetic
clutch relay and flashes the indicator lamp in
the A / C or MAX switch. The conditions in
which the ECU judges the compressor to have
locked are when a slippage rate of 80% or
more has been continued for 3 seconds or
more.

3) Interrupt Screen
a. General
If an abnormal condition occurs in the ve-
hicle system, even if another screen is being
displayed, the interrupt screen automatically
indicates a warning to inform the driver of an
abnormality in the system. The warning in-
dication screen flashes for 5 seconds the
mark of the system in which the abnormality
occurred. Then, it illuminates and remains
displayed until the screen is switched or the
system is reinstated to normal.

THEFT DETERRENT SYSTEM
1. General
The theft deterrent system uses the door lock control system components and some other parts. When
somebody attempts to forcibly enter the vehicle or open the engine hood or luggage compartment door
without a key, or when the battery terminals are removed and reconnected, the theft deterrent system
sounds the vehicle's horn, security horn and flashes the headlights, taillights, hazard lights and interior
light for about one minute to alert. At the same time, it locks all the doors.
The control of this system is effected by the body ECU.

The transmitter of the wireless door lock remote control system is used to unlock the doors.
The ignition key is inserted in the ignition key cylinder and turned until the ignition switch is ON.
Alarm State: a state in which attempted theft can be detected
When an attempted theft is detected, the system sounds the vehicle's horn and the security horn, flashes
the headlights, taillights, and hazard lights, and illuminates the interior light to alert the people in the area.
If any one of the doors is unlocked, and the ignition key is not inserted in the ignition key cylinder, the
system forcefully locks the doors once.
The system transfers to the alert state if the condition (6) described below is met, or, when the system is

REPAIR INSTRUCTIONS
GENERAL INFORMATION
BASIC REPAIR HINT
(a) Use fender, seat and floor covers to keep the vehicle
clean and prevent damage.
(b) During disassembly, keep parts in the appropriate order
to facilitate reassembly.
(c) Installation and removal of battery terminal:
(1) Before performing electrical work, disconnect the
negative (±) terminal cable from the battery.
(2) If it is necessary to disconnect the battery for in-
spection or repair, first disconnect the negative (±)
terminal cable.
(3) When disconnecting the terminal cable, to prevent
damage to battery terminal, loosen the cable nut
and raise the cable straight up without twisting or
prying it.
(4) Clean the battery terminals and cable ends with a
clean shop rag. Do not scrape them with a file or oth-
er abrasive objects.
(5) Install the cable ends to the battery terminals after
loosening the nut, and tighten the nut after installa-
tion. Do not use a hammer to tap the cable ends
onto the terminals.
(6) Be sure the cover for the positive (+) terminal is
properly in place.
(d) Check hose and wiring connectors to make sure that they
are connected securely and correctly.
(e) Non±reusable parts
(1) Always replace cotter pins, gaskets, O±rings, oil
seals, etc. with new ones.
(2) Non±reusable parts are indicated in the component
illustrations by the ºº symbol.
(f) Precoated parts
Precoated parts are bolts, nuts, etc. that are coated with
a seal lock adhesive at the factory.
(1) If a precoated part is retightened, loosened or
caused to move in any way, it must be recoated with
the specified adhesive.
(2) When reusing precoated parts, clean off the old
adhesive and dry with compressed air. Then apply
the specified seal lock adhesive to the bolt, nut or
threads.

PRECAUTION
1. PRECAUTIONS FOR HIGH±VOLTAGE CIRCUIT IN-
SPECTION AND SERVICE
(a) Engineers to be engaged in inspection and servicing re-
lated to high±voltage systems should undergo special
training.
(b) All the high±voltage wire harness connectors are colored
orange: the HV battery and other high±voltage compo-
nents are identified by the ºHigh Voltageº caution labels.
Do not carelessly touch these wires and components.
(c) Before inspecting or servicing the high±voltage system,
be sure to take measures such as wearing insulated
gloves and removing the service plug to prevent electro-
cution. Carry the removed service plug in your pocket to
prevent other technicians from reinstalling it while you are
servicing the vehicle.
(d) After removing the service plug, wait 5 minutes before
touching any of the high±voltage connectors and termi-
nals.
HINT:
The 5 minutes are required to discharge the high±voltage con-
denser inside the inverter.
(e) Before wearing insulated gloves, make sure that they are
not cracked, reptured, torn, or damaged in any other way.
Do not wear wet insulated gloves.
(f) When servicing the vehicle, do not wear a metal object
like a mechanical pencil or scale that may drop acciden-
tally and cause a short circuit.
(g) Before touching a bare high±voltage terminal, wear insu-
lated gloves and ensure that the terminal is not charged
with electricity (approx. 0 V) using an electrical tester.

2. PRECAUTIONS TO BE OBSERVED WHEN INSPECT-
ING OR SERVICING ENGINE COMPARTMENT
The PRIUS, automatically turns the engine ON and OFF when
the ignition switch is set to the ON position provided that the
READY light on the instrument panel is it.
Before inspecting or servicing the engine compartment, there-
fore, remove the ignition switch key.
3. ACTIONS TO BE TAKEN WHEN BATTERIES ARE DE-
PLETED
(a) Actions to be taken when the auxiliary battery is depleted
HINT:
The following phenomena indicate that the auxiliary battery is
depleted:

No display appears on the instrument panel when you
turn the ignition switch to the ON position.

The hybrid system does not start.

The headlights are dark.

The sound from the horn is weak.
NOTICE:
Never use a quick charger.
(1) Move the shift lever to the P position, and engage
the parking brake.
(2) Remove the ignition key plate from the ignition
switch.
(3) Using a booster cable, connect the 12 V battery of
the rescue vehicle and auxiliary battery of the
stalled vehicle, as shown in the illustration.
(4) Start the engine of the rescue vehicle and run the
engine at a speed slightly higher than the idling
speed for 5 minutes to charge the auxiliary battery
of the stalled vehicle.
(5) Turn the ignition switch of the stalled vehicle to the
START position to start the hybrid system.
If the hybrid system fails to start and the master and HV battery
warning lights come on, the HV battery may have been dis-
charged.
(6) Disconnect the booster cable in the reverse way of
the connection procedure.
NOTICE:
If the auxiliary battery needs to be replaced, replace it only
with a 12 V battery specially designed for the use of the
PRIUS.
