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.

3. Wiring Diagram
4. Construction
The engine immobiliser system consists of the transponder key (ignition key), transponder key coil, trans-
ponder key amplifier, and ECM.
Transponder Key (Ignition Key)
A transponder chip is embedded in the grip of the
ignition key. Each transponder chip contains an
individual transponder key-code (ID code). The
key does not need an internal battery to transmit
a key code.
Transponder Key Coil and Transponder Key Amplifier
The transponder key coil is a ring-shaped coil installed around the ignition key cylinder. The transponder
key amplifier is installed in the back of the key cylinder.
An electrical power circuit to provide power to the transponder key coil has been enclosed in the amplifier.
ECM
The control circuit of the engine immobiliser system has been integrated inside the ECM. As a result, the
time has been reduced taken for the engine to start in case of mismatching key code thus improving the
system's theft deterrent performance.
A maximum of 10 different transponder key codes (master key: 7 types, sub key: 3 types) can be registered
in the ECM.
