CONSTRUCTION AND OPERATION
1. Heater Control Panel
As in the previous model, the rotary switch and lever type heater control panel has been adopted.
The new model uses a larger rotary switch to realize excellent control.
2. Air Conditioning Unit
As in the previous model, the air conditioning unit incorporates a blower, heater and cooler units. This provides high
rigidity and lower ventilating resistance.
Blower Unit
The duct size of the blower unit has been enlarged to reduce ventilating resistance.

3. Defroster Nozzle
The front defroster nozzle inner wall is modified into a radial configuration for a smoother air flow and improved
defroster performance.
4. Air Conditioning Amplifier
On the new Camry, the air conditioning amplifier that is provided on the 1MZ±FE engine model is an individual
amplifier unit type and on the 5S±FE engine model is a type that is integrated with the ECM.
The air conditioning amplifier controls the air conditioning system in accordance with the signals received from
sensors, switches, etc.
Function
Details
Magnetic Clutch Relay Control
When the blower switch and the air conditioning switch are turned on to-
gether, or when the air outlet mode is switched to defroster, the magnetic
clutch relay turns on and activates the compressor.
When one of the following conditions is met while the compressor is
turned on, the magnetic clutch relay is turned off and stops the compres-
sor:
i) The air temperature immediately after passing through the evaporator
is detected to be below 3C (37.4F) by the thermistor.
ii) The compressor speed detected by the lock sensor is compared with
the engine speed signal, and the compressor's slip rate exceeds a pre-
determined level (compressor locked).
iii) ªAir conditioner cutº was requested by the ECM to maintain engine
performance or idling speed.
Compressor Delay ControlWhen the air conditioning switch is turned on, the engagement of the mag-
netic clutch is delayed.
Air Conditioning Indicator Light
Control
When the blower switch and the air conditioning switch are turned on to-
gether, or when the air outlet mode is switched to defroster, and the com-
pressor is activated, the indicator lamp of the air conditioning switch is
turned on.
If compressure lock occurs during compressor operation, the indicator
lamp flashes every 1 second.

ACCESSORIES
DESCRIPTION
The new Camry includes the accessory systems shown in the below.
System
Outline
Power Window System
The power window system includes one±touch auto down and key±off opera-
tion functions. The one±touch auto down function automatically opens the
driver 's door window fully. The key±off operation function makes it possible
to operate the power windows for approximately 45 seconds after the igni-
tion key is turned to the ACC or LOCK position, if the front doors are not
opened.
The basic construction and operation of this system are the same as in the
previous model.
Door Lock Control System
This system has a ªkey±linked lock and unlock functionº and a ªkey±confine
prevention functionº. All doors can be locked and unlocked simultaneously
by a key operation at the front right or left foor. (The key needs to be oper-
ated twice to unlock all the doors at the driver's door.) If the door lock opera-
tion is performed when one of the front doors is open and the ignition key is
inserted in the key cylinder, doors are unlocked automatically to prevent the
ignition key from being left inside the vehicle.
The basic construction and operation are the same as in the previous model.
Wireless Door Lock Remote Con-
trol System
A remote control system in which the lock and unlock functions of all doors
and panic alarm function can be controlled by the signals emitted from a
transmitter is adopted. The transmitter is also provided with a 2±step unlock
function to unlock all the doors by pressing the switch twice.
The basic construction and operation are the same as in the '96 Avalon.
However, certain functions have been changed. For details, see page 107.
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 re-
connected, this system sounds the horn and flashes the headlights and tail-
lights for about 1 minute to alert the owner. At the same time, it locks all the
doors and electronically disconnects the starter.
The basic operation is the same as in the '96 Avalon.
Power Seat
As in the previous model, the front seats are power assisted by electric mo-
tors so that the seat positions can be adjusted easily by a simple switch op-
eration.
The basic construction and operation are the same as in the previous model.

SRS Airbag
The SRS (Supplemental Restraint System) airbag is provided for the driver
and front passenger. The SRS airbag has been designed to lessen the shock to
the head and chest of the driver and front passenger in the event of a frontal
impact collision as a supplement to the seat belt.
A 1±sensor type airbag system is used in which the detection of decelera-
tion during a collision as well as control of the airbag system is accom-
plished by the airbag sensor assembly.
The basic construction and operation are the same as in the '96 Avalon.
However, the inflator for front passsenger and airbag sensor assembly have
been changed.
For details, see page 111.
Cruise Control System
Once it has been set at a desired vehicle speed, this system automatically
adjusts the engine throttle position to maintain the vehicle speed at the de-
sired speed without operating the acceleration pedal.
The basic construction and operation are the same as in the previous model.
However, in the new model, a new type acutator has been adopted. Also, the
functions of the cruise control ECU has been changed. For details, see page
116.
Moon Roof
The moon roof is a tilt±up and sliding type the same as in the previous mod-
el. This system includes ªkey±off operationº, which is the same as with the
power window system. The new model offers an additional ªone±touch slide
openº function which enables the moon roof to fully open when the slide
switch is pressed toward the opening side for a few seconds.
Electrical Remote Control Mirror
The electrical remote control mirrors used in the previous model are also
used in the new model. Also, the internal heater to remove water drops from
the mirror surface is provided.
Key Reminder System
When the driver's door is opened with the ignition key in the ACC or LOCK
position, this system sounds a buzzer to warn the driver that the ignition key
has not been removed.
The basic construction and operation are the same as in the previous model.

WIRELESS DOOR LOCK REMOTE CONTROL SYSTEM
1. General
The wireless door lock remote control system is a conventint system for locking and unlocking all the doors at a
distance.
The basic construction and operation of this system are the same as in the '96 Avalon. However, the following items
have been changed.
The trunk lid open operation, which is provided on the '96 Avalon, has not been adopted.
A panic alarm operation, which activates the alarm of the theft±deterrent system, has been newly adopted.
For ease of verification of the operation of this system, the parking lights and taillights flash to inform that the
operation has been completed.

3. Construction
Transmitter
The transmitter is a key±holder type, which is
separate from the ignition key. the lock and unlock
functions of all doors can be controlled by operating
the switches on the ransmitter. Also, this transmitter
is equipped with a panic switch which activates the
security alarm of the theft deterrent system.
