INTRODUCTION:

There are two variations of vehicle security systems and they operate using one of the
following highly secure remote controls:

 Original Toyota key remote (Alarms: AK4218, ACS71-89020, ACS71-89020-CS & ACS71-

75030)

 Alarm (Cobra) remote control (Alarms: AK4169, ACS71-89030 & ACS71-89030-CS)

To programme extra remotes for either alarm systems, please contact your nearest Toyota
or Cobra dealer.

The protection of your vehicle is assured by interior movement sensors and the alarm
system is self-protected against system attack. During an alarm, the alarm siren will sound
and the vehicle hazard lights will flash.

Product functions

The alarm system performs the following functions:

 Perimetric protection (doors, boot and bonnet)
 Interior and window breakage protection (by ultrasonic sensors)
 Alarm system tampering protection
 Protection against unauthorised starting of the engine
 Digital high powered siren with battery back-up
 Acoustic and visual alarm signalisation
 Alarm system status and diagnostic indication light (LED)
 Optional protection features can be added (inclination sensor and/or PIR sensor).

Alarm operation

The alarm is activated in the following situations:

 A locked door or boot is opened in any way other than using either the alarm system OE

key remote or alarm (Cobra) remote control

 The bonnet is opened while the vehicle is locked
 The intrusion sensor is activated (when the sensor detects something moving inside the

vehicle or a window is broken)

 The vehicle battery terminal is disconnected while the alarm system is armed.

Remarks

The intrusion sensor may be activated (triggered) by any of the following:

 Dangling accessories
 Automatic or high pressure car washes
 The impact of hail, lighting strikes or other kinds of impact or continuous vibrations
 Any partially open window, door ajar or sliding roof.

Note:

- The intrusion sensor can be by-passed (deactivated), see chapter, 2.4. Arming without

intrusion sensor

1. Personal PIN code

The alarm system utilises a unique 4 digit personal identification number “PIN” code.
The PIN code facilitates the alarm programming, manual arm / disarm and emergency
override operation in case the remote control stops working.

The unique PIN code is printed on a PIN code card (credit card size) and has initially been
placed in the vehicles document wallet.

You should keep this card always with you. Do not leave it the vehicle.

If you have lost or want to change the PIN code, please contact your nearest Cobra or
Toyota dealer.

To enter the PIN code

1

Press the button on the LED push button the number of times that
corresponds to the first digit of the PIN code (press with a maximum of 1.5
seconds between one press and the next).
If the LED is already on when the button is pressed, it will go out.

2

Wait for the LED to flash indicating that the next digit can be entered.

3

Repeat the process for all four digits.

The alarm system will be armed when the vehicle is Locked and disarmed when the vehicle
is unlocked using the remote control.

2.1. To ARM the alarm system

3. Features

As well as the alarm functions, some extra features are available which can be activated /
deactivated. To activate or deactivate any of them please contact your Cobra or Toyota
dealer.

3.1. Door ajar warning

This feature is enabled by default. If any door or boot is not fully closed when the remote
lock button is pressed, the system will sound (chirp) 10 times. The system will stop
sounding when all the doors are closed, or if the remote control unlock button is pressed.

If the bonnet is not fully closed when the remote lock button is pressed, the system will
sound (chirp) 3 times.

Note:

- The alarm system will arm, even if a door or bonnet is open.

The alarm override is used if the user loses the remote key or control, or the remote
battery is flat.

To enter the PIN code

1

Press the button on the LED push button the number of times that
corresponds to the first digit of the PIN code (press with a maximum of 1.5
seconds between one press and the next).
If the LED is already on when the button is pressed, it will go out.

2

Wait for the LED to flash indicating that the next digit can be entered.

3

3.3. Ignition controlled door lock

This feature is disabled by default. To enable it, please contact your Cobra or Toyota
dealer.
When the vehicle ignition is turned ON and all doors are closed, the system will lock the
doors.
The alarm system will unlock all the doors when the ignition is turned OFF.

3.4. Passive arming

This feature is disabled by default and can be enabled by your Cobra or Toyota dealer.

Passive arming mode arms the alarm system automatically without the vehicle being
locked. It protects the vehicle in case you forget to lock it.

When this option is activated, it will arm the alarm system after the following:

1. The vehicle’s ignition has been turned off.

2. A door has been opened and all doors have been closed again.

If any door is opened when the alarm system is in passive arming, the siren will

sound unless the unlock button on the remote control is pressed.

Note:

- During passive arming mode, the intrusion (ultrasonic) sensors are activated.

- If the vehicle is locked using the remote control, the alarm system shifts to normal
arming mode.

Important:

- The system does NOT lock any doors, only arms the alarm system.

12

3.5. Vehicle finder

This feature is enabled by default and can be disabled by your Cobra or Toyota dealer.

Vehicle finder enables the user to manually flash the hazard lights 4 times to help locate
the vehicle when the system is in the fully armed state.

To activate vehicle finder, proceed as follows:

Activation steps

Hazard light

indication

Alarm status light (LED)

1

Lock the vehicle
using the remote
control

Flashes once

ON for 30 seconds
2

once

Flashes 4 times

LED flashes (at a steady rate)

3.6. Alarm memory

If the alarm went off during your absence, the hazard lights will flash 5 times when the
doors are unlocked and the system will chirp 5 times.
The system memorises the last alarm trigger. This can then be identified by counting the
number of flashes of the alarm LED before switching the ignition ON.

1 flash: Doors
2 flashes: Intrusion (ultrasonic) sensor
3 flashes: Bonnet
4 flashes: Ignition switch (hot wire)
5 flashes: Boot / Side doors
6 flashes: Alarm system wiring or siren
7 flashes: Optional sensor

Note:

- There is a pause of 2 seconds between 2 different alarm memories.

Important:

- If you suspect that the alarm system is sounding due to false alarms, please count the

number of LED flashes and contact your Cobra or Toyota dealer.

3.7. Garage mode

If you have to take your vehicle to be serviced and you do not want to provide the remote
controlled key, the alarm system can deactivated for a limited period of time.
During garage mode, all the alarm system features are inhibited.

Garage mode has to be manually activated by the following procedure:

1. Disarm the system using the remote control.

2. Insert the ignition key and turn the ignition ON.

3. Open the driver’s door.

4. Entre alarm pin code or press for 3 seconds on the remote control lock button.

If this feature is enabled, the system will chirp once when armed and twice when disarmed
using the remote control.

3.9. Chirp volume adjustment

The volume of the chirp can be adjusted. Please contact you Cobra or Toyota dealer.

4. Remote Control

When the alarm (Cobra) remote control battery is low the remote LED flashes erratically or
slowly when any button is pressed.

Note:
