Panic Mode
The panic mode allows the security system to sound the alarm with the remote transmitter in order to attract attention.
When the PANIC butten is pressed and held for 2 seconds, the alarm will sound and the exterior lights will flash for
about 30 seconds.
The panic mode can be canceled at anytime by pressing any button on the remote transmitter or by turning the
ignition switch ON (II). The panic mode will not function if the ignition switch is ON (II).
Keyless Entry System
NOTE: '99-04 LX models have an accessory keyless entry and security system. '99-00 EX models have a factory
keyless entry and an accessory security system. For an accessory keyless entry or security system, refer to the ETM
and accessory owner's manual.
The security alarm system is integrated with the keyless entry and multiplex systems on '01-04 EX, EXL.
The keyless entry system allows you to lock and unlock the vehicle with the remote transmitter. When you push the
LOCK button, all doors lock. When you push the UNLOCK button once, only the driver's door unlocks. The other doors
and the tailgate door will unlock when you push the button a second time.
When the switch for the ceiling light is in the center position, it will come on when you press the UNLOCK button. If
you do not open a door, the light will go off in about 30 seconds, the doors will automatically relock, and the security
system will rearm. If you relock the doors with the remote transmitter within 30 seconds, the light will go off
immediately.
You cannot lock the doors with the remote transmitter if a door or the tailgate is not fully closed, or if the key is in the
ignition switch. If the tailgate or hood is not closed, the doors will lock and unlock, but the security system will not be
armed until the tailgate and hood are closed.
The system will signal you when the doors lock and unlock by flashing the parking lights, side marker lights, and
taillights: once when they lock, and twice when they unlock.
When you press the LOCK button a second time within 5 seconds after you have locked the doors, the horn will sound
once to verify that the security system will be set.
If the lights do not flash, make sure the doors, the hood, and the tailgate are closed and locked. The most common
failure is a door, hood, tailgate, lock knob, ignition key, or door/tailgate key cylinder input. Check that the security
indicator blinks. If the security alarm system does not arm, refer to the multiplex mode or security input tests.
