SYSTEM DESCRIPTION

SECURITY ALARM SYSTEM

The security alarm system is integrated with the multiplex integrated control system, and arms automatically
after the doors, hood, and trunk lid are closed and locked. For the system to arm, the ignition switch must be
off, the key must be removed, and the MICU must receive signals that the doors, hood, and trunk lid are
closed and locked. The alarm can be disarmed at any time by unlocking the driver's door with the key or
pressing the UNLOCK button on the remote.

When everything is closed and locked, the only inputs that are grounded, and have 0 V, are the driver's door
lock knob switch (LOCK position), and the audio unit. In other words, all of the other switches are open,
and have about 0.8 V in sleep mode or 5 V or more in awake mode, including the key cylinder switches. The
security indicator in the gauge control module begins to flash immediately after the doors, hood, and trunk
lid are closed and locked, and shorty later, the security system arms and the security indicator flashes on for
a shorter amount of time than before. If the security indicator does not flash, the system is not arming. If the
vehicle is completely closed and locked, a beep sounds and parking lights flash to confirm the security alarm
system is armed if the LOCK button is pressed a second time within 5 seconds, and the keyless lock
acknowledgment is turned on.

If one of the switches is misadjusted or shorted internally (0 V), or there is a short in the circuit (0 V), the
security system will not arm. A switch that is slightly misadjusted can cause the alarm to sound for no
apparent reason. In this case, a significant change in outside air temperature, the vibration of a passing
vehicle, or something bumping into the vehicle could cause the alarm to sound. There is no glass breakage
or motion detector feature.

If anything is opened or improperly unlocked after the system is armed, the control unit receives a ground
signal from that switch, the 0.8-5.0 V reference drops to 0 V, and the system sounds the alarm. If the audio
unit is disconnected, the input loses its ground, and the input voltage goes to 0.8-5.0 V, and the system
sounds the alarm. The system sounds the alarm when any of following occur while the security system is
armed:



A door or the trunk lid is forced open



A door is unlocked without using the built-in key or the remote



The hood is opened



The audio unit is disconnected



The remote panic is operated



The ignition switch is turned ON (II)

When the system sounds the alarm, the horns sound and the exterior lights flash for 2 minutes. The alarm
can be stopped at any time by unlocking the driver's door with the key or by pressing any button on the
remote.

PANIC MODE

The panic mode sounds the alarm in order to attract attention. When the PANIC button on the remote is
pressed and held for about 2 seconds, the alarm sounds and the exterior lights flash for about 20 seconds.

The panic mode can be cancelled at anytime by pressing any button on the remote or by turning the ignition
switch ON (II). The panic mode will not function if the ignition switch is ON (II).

KEYLESS ENTRY SYSTEM

The keyless entry system is integrated with the multiplex integrated control system. Remotes 1 and 2
(Identified on the back of each remote) are linked to the DPMS, keyless access control unit, the climate
control settings, the custom memory settings (in the MID), and the illumination settings. Depending on
which remote unlocks the vehicle, these settings are chosen.

Some functions of the security, keyless entry, and power door locks can be customized using the MID

keyless memory setting. They include:



AUTO DOOR LOCK: Door locking can be turned off, or turned on when shifting from Park or at a
speed above 10 mph.



AUTO DOOR UNLOCK: Door unlocking can be turned off, or turned on when shifting to Park or
turning the ignition switch OFF.



WHENEVER UNLOCKING: Door unlocking can be set to unlock all doors or only the driver's door
on the first push.



KEYLESS DOOR LOCK ACKNOWLEDGMENT: The beep and the front parking lights can be
turned on or off when pressing the LOCK/UNLOCK button on the remote.



SECURITY RELOCK TIMER: Select the time (30,60, or 90 sec.) that the doors relock if you unlock
the doors with the remote, but do not open any of them.



HEADLIGHT AUTO OFF TIMER: Select time (0,15,30, or 60 sec.) to turn the headlights off after
removing the key from the ignition opening, then closing the driver's door.



AUTO LIGHT SENSITIVITY: Automatic lighting sensor sensitivity can be adjusted five steps
(MIN/LOW/MID/HIGH/ MAX).



INTERIOR LIGHT DIMMING TIMER: Select the dimming time (15,30, or 60 sec.) of the interior
lights after closing the door with the key removed from the ignition.

The remotes can be linked and unlinked to the keyless memory settings by pressing the LOCK and
UNLOCK buttons at the same time for about 1 second. The LED on the remote blinks twice when linked,
and once when unlinked.

The keyless entry system allows you to lock and unlock the vehicle with the remote. When you press the
LOCK button, all the doors lock (unless any one of the doors is not fully closed or the key is in the ignition
switch). When you press the UNLOCK button the first time, only the driver's door unlocks, if keyless
memory setting "WHENEVER UNLOCKING" is set to Driver's Door. The other doors unlock when you
press the UNLOCK button a second time. All the doors unlock when you press the UNLOCK button the
first time if keyless memory setting "WHENEVER UNLOCKING" is set to All Doors.

If the UNLOCK button is pressed, released, then pressed and held, the power windows and the moonroof
begin to open. The windows and the moonroof stop if the button is released. The windows and moonroof
cannot be closed with the remote. See power windows for more information and troubleshooting.

When the interior lights switch is in the "DOOR" position, the individual map lights will come on when the
UNLOCK button is pressed. If a door is not opened, the lights will go off in about 30,60, or 90 seconds
(depending on the keyless memory setting "SECURITY RELOCK TIMER"), and the doors will relock. If
the doors are locked with the remote within 30 seconds, the lights will go off immediately.

POWER DOOR LOCK SYSTEM

The power door lock system locks and unlocks all four doors with the driver's or passenger's master door
lock switch. The doors can be locked and unlocked using the remote's built-in key in the driver's door key
cylinder switch. If the key is turned counterclockwise, all the doors lock. If the key is turned clockwise once,
the driver's door unlocks, and when the key is released, then turned again, the other doors unlock.

NOTE:

The doors will not lock with the remote if a door is not fully closed, or if the
remote's built-in key is in the ignition switch.
