VEHICLES)To make the vehicle theftproof, this system is so
designed that the headlights go on and off and the
horn is sounded intermittently for ‘about threeminutes when the locked door, hood or liftgate has
been forced open without using a key.
Furthermore, the starter circuit is interrupted so that
the engine may not be operated, making the vehicle
theftproof.

and locked, the rear hatch is closed, and the
hood is closed---t SYSTEM ARMED4uthorized

8-32ELECTRICAL - Theft-alarm System
THEFT-ALARM SYSTEM
NOOIAAAWhen the theft-alarm system has been armed by a
fixed sequence for locking the doors with the key or
without the key, if thereafter a door, the rear hatch
or the hood is opened in an unauthorized way. the
horn will sound intermittently for period of approx-
imately three minutes, and. at the same time, the
headlights will flash on and off, thus providing
audible and visual warning. signals.Furthermore, the starter circuit is interrupted in SIa way that the engine cannot be started, if
‘Lignition key is not used. Note that this system is
controlled by the electronic control unit (ECU).
This ECU includes an independent microcomputer
for the exclusive use of the theft-alarm system. This
microcomputer arms, disarms, activates and deacti-
vate the alarm system.
The system is composed of the components de-
scribed below.

ELECTRICAL - Theft-alarm System8-33ARMING THE SYSTEM
After the following procedures have been completed, the SECURITY light illuminates for about 20 seconds,
and when illumination stops, the system is armed.
(1) Pull out the ignition key from the key cylinder.
(2) Open a door. (The other door is closed.)
(3) Lock the door with the key or the
keyless-locking method.
(The central door locking system will then function to lock all doors.)
NOTE(1) The system is set regardless of whether the hood and liftgate are open or
closed, and is armed as
soon as the light goes out.
(2) Even after the system has been armed, if the key is used to open the liftgate, the system will not be
activated; when the liftgate is then
closed, moreover, the system will be armed.
DISARMING THE SYSTEM
(1) The system will be disarmed if the key is used to unlock a door.
(2) If the system is armed while the driver is still in the vehicle, the system can be disarmed by inserting the
ignition key and turning it to the ACC or ON position.
(3) If the door lock is unlocked while closing the door or the door is ajar.
(4) If the door is unfastened while the SECURITY light illuminates.
ACTIVATING THE ALARM
(1) if an attempt is made to open a door, the liftgate or the hood, without using the key, while the system is
armed, the horn will sound intermittently and the headlights will flash on and off for approximately
three,
minutes.Furthermore, the starter circuit is interrupted at this time also, making starting of the engine impossible.
(2) if a further attempt at *forcible entry is made after the first three-minute alarm has finished, the
three-minute alarm will be activated again.
DEACTIVATING THE ALARM
(1) To deactivate the alarm, insert the key into the door’s key cylinder and turn the key.
(2) The alarm is deactivated and the system is disarmed when the iiftgate is unlocked with the key.
CHECKING THE SYSTEM OPERATION
The activation/operation of the system can be checked by following the steps below.
(1) Turn the ignition key to the ON position and then use the power-window switch to fully open the window
at the driver’s seat side.
(2) Turn the ignition key to the LOCK position and then remove the key from the ignition.
(3) Open only the driver’s door, and close all the other doors, as well as the hood and the rear hatch.
(4) Lock the driver’s door by the key or the
keyless-locking method.
(5) All doors will then be
locked, and the SECURITY light (within the combination meter) will illuminate; check
to be sure that illumination stops in about 20 seconds.
(6) After about two seconds have passed after the SECURITY light illumination stopped, reach through the
window of the driver’s door, pull up the lock lever to unlock the door, and then open the door.
(7) Check to be sure that, when the door is opened, the horn starts sounding and the headlights flash on and
Off.
(8) To stop the alarm, insert the key into the door’s key cylinder and turn the key.
!?iEeck the alarm for the opening of the liftgate or hood open the liftgate (or the hood) by using the
remote liftgate release lever (or the hood release lever),
located at the driver’s seat side either before the
alarm is activated by the opening of a door, or after the finish of the first three-minute alarm.
