1. OUTLINE OF THEFT DETERRENT SYSTEM
(a) When the theft deterrent system detects that the vehicle is being tampered with, the system sets off
the alarm, causing the horns to sound and the lights to light up or blink in order to alert people around
the vehicle to the theft.
(b) The theft deterrent system has an active arming mode; a disarmed state, an arming preparation state,
an armed state and an alarm sounding state.

When no key is in the ignition key cylinder and 0.4 seconds have elapsed after the previous out-
put of a forced door lock signal, the doors will be forced to lock if any of the following conditions

function will record it. Whenever you cancel the theft deterrent system, the alarm memory function
causes the taillights to light up for 2 seconds in order to inform you that the alarm has been set off.
(1) Conditions of the alarm memory function that cause the taillights to light up:
When the theft deterrent system has entered into the alarm sounding state (tampering has been
detected) even once, the taillights will light up for 2 seconds if any of the following conditions is
present.

Switched to the disarmed state from the armed state.
5. SECURITY INDICATOR OUTPUT
(a) The theft warning ECU outputs a signal to light up the security indicator, according to the state of the
theft deterrent system. However, some of the actual lighting conditions of the security indicator are dif-
ferent from the outputs of the theft warning ECU.
Output:

6. INTRUSION (THEFT WARNING) SENSOR
(a) Function of the intrusion sensor:
The intrusion sensor (theft warning redar sensor) senses any moving object by using ultrasonic waves
and outputs the signals to communicate an intrusion to the theft warning ECU so that the theft deterrent
system can set off the alarm.
When the theft deterrent system is switched to the arming preparation state, the intrusion sensor is
supplied with S+B by the theft warning ECU. This causes the theft deterrent system to set off the alarm
when the signal is input from the intrusion sensor in a situation such as the window glass being broken.
(b) Press the intrusion sensor OFF switch.
HINT:
The theft deterrent system can be set (switched to the arming preparation state) with the intrusion sensor
OFF when an animal is left inside the vehicle.
(1) Make sure that the theft deterrent system is in the disarmed state.
(2) Press the intrusion sensor OFF switch once.
HINT:
The intrusion sensor and the OFF switch are provided on the roof console box in the vehicle front interior.
NOTICE:
The intrusion sensor returns to ON (initial state) when the doors are unlocked by the wireless opera-
tion.
7. THEFT WARNING (SELF±POWER) SIREN
(a) The theft warning siren has an internal battery. If any of the vehicle's battery or communication lines
are opened, the theft warning siren detects it by itself and sounds. Although the theft warning siren
usually sounds by receiving a signal from the theft warning ECU usually, the theft warning siren can
sound using its internal battery in case that the vehicle's battery is opened.
(b) The theft warning ECU sends an arming signal to the theft warning siren while transferring to the armed
state, as well as sending a disarming signal to the siren while transferring to the disarmed state. Addi-
tionally, the theft warning ECU can sound the theft warning siren by sending an alarm signal in the
alarm sounding state.
