THE NEW WORLD OF
ANTI-THEFT
TECHNOLOGY
This Scion vehicle may be equipped
with an electronic “immobilizer”
anti-theft system. When the key is
inserted into the ignition switch it
transmits an electronic code to an
immobilizer computer. The engine will
only start if the code in the key matches
the code in the immobilizer. If the code
does not match, the immobilizer
disables the ignition and fuel systems.
While an exact physical copy of the key
will open the door and allow retrieval of
items locked in the vehicle, it won’t
start the vehicle unless the key has the
same code as the immobilizer.
SECURITY
For security purposes, access to key
codes and service procedures for
electronically registering replacement
keys is restricted. Only an Authorized
Servicing Dealership* or certain
bonded/registered independent
locksmiths can generate replacement
keys.
* For the purposes of this system, an Authorized Servicing Dealership is a Scion dealership or a Toyotadealership.

REPLACING THE KEY
Upon purchase, each vehicle should
have two master keys and an
aluminum tag with a key-code
imprinted on it.
To generate a fully functional
replacement key (one that will both
open the doors and start the engine),
one of the master keys is required. To
make a key that will open the door for
retrieval of items locked inside the
vehicle, the aluminum key-code tag can
be used. If a master key or the
aluminum key-code tag is not available,
an Authorized Servicing Dealership or
certain registered locksmiths can
obtain the key code from a
restricted-access database. These
businesses can also access a service
utility to reprogram the immobilizer if
all registered master keys have been
lost. If an Authorized Servicing
Dealership is not available, please refer
towww.aloa.org to find a
bonded/registered locksmith who
performs high security key service.
KEEPING THE KEY SAFE
Replacing an immobilizer key may be
costly. It is advisable to keep a spare
master key and the aluminum key-code
tag in a safe place. If you record the
key-code in more than one place, do
not record it in a way that can be easily
identified and associated with the
vehicle. It is wise to keep a copy of the
key-code outside of the vehicle.
If the vehicle was delivered with less
than two keys and the aluminum
key-code tag, consider having an
Authorized Servicing Dealership or a
qualified independent automotive
locksmith make a duplicate key before
you need it.

an ethylene-glycol type coolant. Inspect
the radiator, condenser and/or

and clean if necessary. Inspect hoses
and connections for corrosion and
leaks. Tighten connections and replace
parts when necessary. A qualified
technician should perform these
operations. (For further details, refer to

Your Scion is equipped with Genuine
Toyota Super Long-Life Coolant.

high-quality non-silicate,
non-amine, non-borate

long-life hybrid organic acid
technology (i.e., a combination of
low phosphates and organic acids).
If another type of ethylene-glycol
coolant is used, replacement
intervals may be different.

refill the engine oil at specified
intervals. For recommended oil grade
and viscosity, refer to the
Owner’s
Manual.
