INTRODUCTION
THE IMMOBILIZER KEY

THE NEW WORLD OF
ANTI-THEFT TECHNOLOGY
This Toyota 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 a Toyota dealer
or certain bonded/registered independent
locksmiths can generate replacement keys.

INTRODUCTION


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,
a Toyota dealer 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 a Toyota dealer is not available,
please refer to www.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 the Toyota dealer or a
qualified independent automotive locksmith
make a duplicate key before you need it.

YOUR WARRANTY RIGHTS
AND OBLIGATIONS
The California Air Resources Board (CARB)

vehicles must be designed, built and
equipped to meet the state’s stringent
anti-smog standards. CARB regulations
require that Toyota must warrant the
emission control system on your vehicle
for the time periods indicated on the next
page, provided there has been no abuse,
neglect or improper maintenance of
your vehicle.
Your emission control system may include
parts such as the fuel injection system,
ignition system, catalytic converter and
engine computer. Also included may be
hoses, belts, connectors and other
emissions-related assemblies.
Where a warrantable condition exists,
Toyota will repair your vehicle at no cost
to you, including diagnosis, parts and labor.

MAINTENANCE
MAINTAINING YOUR WARRANTY
IMPORTANT MAINTENANCE
INFORMATION
It is especially important to both
routinely check your vehicle’s engine
oil level (once a month) and regularly
replace the engine oil and oil filter
(see the Maintenance Log section of
this booklet to determine how often
you should change your vehicle’s oil
and filter). Failure to do so can cause
oil starvation and/or oil gelling, which
can result in severe damage to your
vehicle and require costly repairs that
are not covered by the New Vehicle
Limited Warranty.
Maintenance Records
Maintaining your vehicle according to
the recommendations in this booklet is
required to ensure that your warranty
coverage remains intact. You should keep
detailed records of vehicle maintenance,
including date of service, mileage at time
of service and a description of service
and/or parts installation performed. The
scheduled maintenance log in this booklet
can help you document this information. If
you sell your vehicle, be sure to give your
maintenance records to the new owner.
Toyota will not deny a warranty claim
solely because you do not have records
to show that you maintained your vehicle.
However, damage or failure caused by lack
of proper maintenance is not covered
under warranty.


Maintenance Providers
Maintenance and repair services may be
performed by you or by any automotive
service provider you choose. Toyota will
not deny a warranty claim solely because
you used a service provider other than a
Toyota dealership for maintenance and
repairs. However, damage or failure
caused by improper maintenance or
repairs is not covered under warranty.
Dealer-Recommended
Maintenance
Your dealer may recommend more
frequent maintenance intervals or more
maintenance services than those listed in
the scheduled maintenance log. These
additional services are not required to
maintain your warranty coverage. Ask
your dealer to explain any recommended
maintenance not included in the scheduled
maintenance log.
For a complete description of Toyota
warranty coverages, see the Warranty
Information portion of this booklet.

MAINTENANCE
Special Operating Conditions
In addition to standard maintenance items,
the maintenance log indicates services that
should be performed on vehicles that are
driven under especially demanding
conditions. These “special operating
conditions” and their required maintenance
items are clearly indicated in each chart.
NOTE:
You should perform these additional
maintenance services only if the
majority of your driving is done under
the special operating conditions
indicated. If you only occasionally
drive under these circumstances, it
is not necessary to perform the
additional services.
Engine Oil Selection
Please refer to your Owner’s Manual for the
specific oil viscosity rating recommended
for your vehicle/engine type.
Additional Maintenance
In addition to scheduled maintenance,
your Toyota requires ongoing general
maintenance, such as fluid checks and
visual inspections. These procedures are
explained in the “Maintenance and Care”
section of the Owner’s Manual. Be sure
to perform these procedures regularly to
ensure the most trouble-free operation
of your vehicle.
SuperChrome and
Alloy Wheel Care
If you purchased Genuine Toyota Accessory
SuperChrome or Aluminum Alloy Wheels,
follow these cleaning guidelines to maintain
the appearance of your wheels:
• If wheels are hot, wait for them to cool
before washing.
• Use a soft sponge or cotton cloth to
apply the same mild car-wash soap as
used for the vehicle body. Quickly rinse
off with water. Use a soft cloth to apply
the same car wax as used for the
vehicle body.
• DO NOT USE: Any kind of chemical-
based cleaners, alcohol, solvents,
gasoline, steam cleaners, scouring
pads, wire brushes or coarse abrasives
to clean your wheels.
