Immobilizer System

The immobilizer system allows the engine to start only with a

key the system recognizes.

If someone attempts to start the engine with an unrecognized key, the

engine will not start, thereby helping to prevent vehicle theft.

If you have a problem with the immobilizer system or the key, consult

your Toyota dealer.

●The keys carry a unique electronic code. For this reason, and to assure your

safety, obtaining a replacement key requires some waiting time. They are

only available through your Toyota dealer.

●Always keep a spare key in case one is lost. If a key is lost, consult your

Toyota dealer as soon as possible.

●If you lose a key, your Toyota dealer will reset the electronic codes of your

remaining keys and immobilizer system. Bring all the remaining keys to your

Toyota dealer to reset.

Starting the vehicle with a key that has not been reset is not possible.

NOTICE

●Radio equipment like this is governed by laws in the United States.

Changes or modifications not expressly approved by the party responsible

for compliance could void the user’s authority to operate the equipment.

●To avoid damage to the key, do not:

• Drop the key.

• Get the key wet.

• Expose the key to any kind of magnetic field.

• Expose the key to high temperatures on places such as the dashboard

or hood, under direct sunlight.

●If the engine does not start with the correct key, and the security indicator

light keeps illuminating or flashing, the system may have a malfunction.

Consult your Toyota dealer.

2-8. Security System

Operation

■ Arming

The system is armed when the

ignition is switched from ON to

off.

The security indicator light in

the combination meter flashes

every 2 seconds until the sys-

tem is disarmed.

2

■ Disarming

The system is disarmed when the ignition is switched ON with the

correct programmed key. The security indicator light illuminates for

about 3 seconds and then turns off. If the engine does not start with

the correct key, and the security indicator light remains illuminated

or flashing, try the following:

Make sure the key is within the operational range for signal trans-

mission. Switch the ignition off, and then restart the engine. If the

engine does not start after 3 or more tries, contact your Toyota

dealer.

●The engine may not start and security indicator light may illuminate or flash

if the key is placed in an area where it is difficult for the system to detect the

signal, such as on the dashboard or in the glove compartment. Move the

key to a location within the signal range, switch the ignition off, and then

restart the engine.

●Signals from a TV or radio station, or from a transceiver or mobile telephone

could interfere with your immobilizer system. If you are using the proper key

and the engine fails to start, check the security indicator light.

●If the security indicator light flashes continuously while you are driving, do

not shut off the engine. Go to your Toyota dealer and have it checked. If the

engine is shut off while the indicator light is flashing, you will not be able to

restart it.

●Because the electronic codes are reset when the immobilizer system is

repaired, the keys are needed. Make sure to bring all the keys to your Toy-

ota dealer so that they can be programmed.

Theft Deterrent System^

If the theft deterrent system detects an inappropriate entry into

the vehicle, which could result in the vehicle or its contents

being stolen, the alarm alerts the surrounding area of an abnor-

mality by sounding the horn and flashing the hazard warning

lights.

The system will not function unless it’s properly armed. So when you

leave the vehicle, follow the arming procedure correctly.

Operation

■ System triggering conditions

The horn sounds intermittently and the hazard warning lights flash

for about 30 seconds when the system is triggered by any one of

the following:

inside door-lock knob.

• Forcing open a door, the hood or the liftgate/trunk lid.

• Opening the hood by operating the hood release handle.

• Switching the ignition ON without using the push button start.

If the system is triggered again, the lights and horn will activate until

the driver’s door or the liftgate/trunk lid is unlocked with the smart

key.

With the advanced keyless function:

The lights and horn can also be deactivated by pressing the request

switch on a door.

●The liftgate/trunk lid does not open while the theft deterrent system is oper-

ating.

●If the battery goes dead while the theft deterrent system is armed, the horn

will activate and the hazard warning lights will flash when the battery is

charged or replaced.
