SEAT BELT WARNING SYSTEM
1. General
A seat belt warning for the front passenger has been newly provided. When the front passenger seat is occu-
pied but its seat belt is not being worn, this function flashes a warning light to inform the front passenger that
the seat belt is not being worn.
2. Seat Belt Warning for Front Passenger
Construction
The seat belt warning for the front passenger consists of the front passenger seat belt buckle / retractor
switch, occupant detection sensor, seat belt warning light for the front passenger.
1) Belt Warning Occupant Detection Sensor
The occupant detection sensor, which is enclosed in the seat cushion of the front passenger seat, is used
to detect whether or not the front passenger seat is occupied.
This sensor, which is shaped as illustrated below, consists of a construction in which two sheets of elec-
trodes sandwich a spacer. When the occupant is seated, the electrode sheets come in contact with each
other through the hole that is provided in the spacer portion, thus enabling the current to flow.
Thus, the sensor detects whether or not an occupant is seated in the front passenger seat.

2) Front Passenger Seat Belt Buckle / Retractor Switch
The front passenger seat belt buckle / retractor switch is enclosed in the seat belt buckle / retractor of the
front passenger seat to detect whether or not the seat belt for the front passenger is being worn.
3) Seat Belt Warning Light for Front Passenger
The seat belt warning light for front passenger flashes to warn if the front passenger does not have the
seat belt buckled.
Operation
When an occupant is seated in the front passenger seat, the occupant detection sensor activates, thus enab-
ling the system to recognize that the occupant has seated. When the ignition switch is turned ON, a warning
light flashes if the front passenger is not wearing the seat belt. The warning light continues to flash until
the front passenger wears the seat belt.
If the front passenger seat is not occupied, the warning light remains extinct regardless of the condition of
the seat belt.

AUDIO
AVC-LAN
1. General
The AVC-LAN (Audio Visual Communication - Local Area Network) is a communication standard that has
been established by the 6 audio manufacturers that produce audio visual units, which are mounted on Toyota's
production vehicles. This standard, which ensures the mutual interchangeability of the manufacturers' units,
facilitates the connection and control of those units.
The characteristics of an audio system that supports AVC-LAN are described below.
An audio system can be created by selecting the units regardless of the audio unit's manufacturer.
The audio system that was installed in the factory can be freely interchanged or added with commercially
available audio units.
Because this standard enables the manufacturers to develop and produce the audio unit of their specialty,
a wide variety of products can be provided in the audio lineup.
The audio units that are newly developed by the manufacturers can be added to the lineup in a timely man-
ner.
By pre-registering the switch operation of each unit established in the line up into the head unit, each unit
can be controlled by the head unit without adding the transmitter when adding units later.
By adopting the audio system corresponded to the AVC-LAN standard, audio units can be easily added or
changed with the audio system mounted originally on the vehicle as the base. Thus, the expandability of the
audio system is improved.

2. Communication Outline
In the audio system that uses AVC-LAN, audio units such as a cassette deck or a CD changer are connected
by a communication bus that establishes communication via serial data signals.
In this system, addresses are used to identify the units with which to establish communication. The addresses
can be broadly divided into two types: the physical address that is assigned to each audio unit such as a cas-
sette deck, CD changer, etc.; and the logical address that is assigned to the function that each unit provides,
such as the radio function or the cassette function. The physical addresses are represented by 3-digit numbers
and the logical addresses are represented by 2-digit numbers.
The signals that are exchanged between the units are the unit's control signal, display data, audio signal, etc.,
which have been rendered into serial data. The configuration of the 4 signals indicated below, which are ren-
dered into serial data and transmitted to the each unit, has been established as a uniform AVC-LAN standard.

The illustration below shows an example of an audio system configuration using AVC-LAN.
3. Operation
System Registration
An audio system that uses AVC-LAN performs a registration process to verify the audio units that comprise
the system.
When the ignition switch is turned to the ACC position, the audio units that comprise the system transmit
the logic address in the units, and the physical address is transmitted by the mode control portion that is
integrated in the smallest audio unit (head unit). By receiving these addresses, the mode control portion veri-
fies the units that comprise the system.
By performing this process, all functions can be controlled regardless of the combination of the units that
comprise the system.

Switching the System
An audio system that uses AVC-LAN consists of audio units that are connected in parallel as described in
Fig. 1. Each of the audio units has a switch to connect the unit to the communication bus.
To control the audio units in accordance with the system to be operated, the mode control portion transmits
output ON and output OFF instructions. In accordance with the instruction signals transmitted by the mode
control portion, the units turn their switches ON or OFF to switch the operating unit and system. Fig. 2 shows
an example of a signal exchange that takes place between the mode control unit and each audio unit during
the switching of the system.

4. Diagnosis Function
A diagnostic function that comprises the following 3 functions has been adopted.
A LAN check mode that displays the code number (physical address) of the tuner and connected equip-
ment.
A system check mode that displays the malfunction judgment of the tuner and connected equipment and
its results.
A diagnosis memory mode that displays the malfunction judgment of the tuner and connected equipment
and its results.
For further details on diagnosis function, see the Toyota Service Bulletin (Ref. No. BE-8008).

2. Engine
ORVR (On-board Refueling Vapor Recovery) system has been adopted on the 1MZ-FE engine models.
The basic construction and operation of this system are the same as in the '98 Camry with 5S-FE Engine.
The direction of the rotation of the radiator cooling fan of the 1MZ-FE engine models has been reversed.
A service port has been provided for inspecting the evaporative emission control system on all models.
For details, see the General 1999 Features section.
3. Axles
The rear axle bearing specifications have been partially changed.
4. Brakes
The brake specifications have been partially changed.
5. Body
The attachment method for the front bumper reinforcement has been changed.
The center pillar garnish extends into the vehicle's interior to provide its effectiveness in absorbing the
energy in case the occupant's head collides against the pillar.
A reinforcement has been added to the rocker panel to effectively dissipate the impact energy during a
frontal collision, thus minimizing the deformation of the cabin.
The front, center and rear pillar garnishes provide an impact-absorbing structure consisting of internal ribs
that dampen the impact.
6. Seat
A seat fabric has been changed on the CE grade models to improve the seat appearance.
7. Seat Belt
The shape of the tongue plate has been changed to help improve the usability of the seat belt.
