Before Driving
The system operates only when the driver is in the vehicle or within
operational range while the key is being carried.
■Starting the Engine Operational range
●Starting the engine may be possible even if the key is outside of the vehicle
and extremely close to a door and window, however, always start the engine
from the driver’s seat.
If the vehicle is started and the key is not in the vehicle, the vehicle will not
restart after it is shut off and the ignition is switched to off.
● The trunk is out of the assured operational range, however, if the key (smart
key) is operable the engine will start.
● The engine may not start if the key is placed in the following areas:
• Around the dashboard

• On the rear parcel shelf

Immobilizer System
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.
The immobilizer system allows th e engine to start only with a
key the system recognizes.
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.

Before Driving
■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 of f. If the engine does not start with
the correct key, and th e 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.
