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.

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.
