SAFETY PRECAUTIONS
Your Sienna has both high-voltage DC and AC systems as well as a 12-volt system. Both DC
and AC high voltage are very dangerous and can cause personal injury, severe burns, electric
shock and even fatal injury.
To avoid personal injury, please follow all caution labels attached to high-voltage parts. Do not
touch or attempt to remove or replace any high-voltage (orange-colored) wiring and connectors.
Do not touch the service plug located underneath the access hole in the console box.
If an accident occurs, do not touch any high-voltage wiring, connectors or parts such as the
inverter unit or hybrid vehicle battery assembly.
Do not touch the potassium hydroxide electrolyte that might spill or leak from the hybrid vehicle
battery as the result of an accident. If potassium hydroxide electrolyte gets on your skin or in
your eyes, neutralize it immediately with a saturated boric acid solution (ratio: 80 grams boric
acid to two liters water). Seek immediate medical attention.
If a vehicle fire occurs, extinguish it with a Class D powder-type fire extinguisher.
Toyota recommends having maintenance and repairs for your Sienna performed by
an authorized Toyota dealership. To locate your nearest authorized Toyota dealership,
contact the Toyota Brand Engagement Center at (800) 331-4331 or log on to
www.toyota.com.

INTRODUCTION
A
t Toyota, our top priority is always
our customers. We know your Toyota
is an important part of your life and
something you depend on every day. That’s
why we’re dedicated to building products of
the highest quality and reliability.
Our excellent warranty coverage is
evidence that we stand behind the quality
of our vehicles. We’re confident — as you
should be — that your Toyota will provide
you with many years of enjoyable driving.
To further demonstrate our commitment to
our customers’ satisfaction, occasionally
we may establish a special policy
adjustment to pay for specific repairs that
are no longer covered by warranty. When
we establish such a policy adjustment, we
mail details to all applicable owners we
have on record.
To provide you with added protection
against unexpected service costs, we offer
Toyota Financial Services vehicle service
agreements and Toyota Auto Care and
Toyota Care Plus prepaid maintenance
programs. Each offers plans to meet a
wide variety of needs. Your dealership can
help you select the plan that’s best for you.
Our goal is for every Toyota customer to
enjoy outstanding quality, dependability
and peace of mind throughout their
ownership experience. We want you to be
a satisfied member of the Toyota family
for many miles to come.
This booklet describes the terms of
Toyota warranty coverage as well as
general owner responsibilities. The
scheduled maintenance section
describes your vehicle’s maintenance
requirements. Be sure to review this
information carefully, since proper
maintenance is required to ensure that
warranty coverage remains intact.
All information in this booklet is the latest
available at the time of publication and is
subject to change without notice.

IF YOU NEED ASSISTANCE
INTRODUCTION
B
oth Toyota and your Toyota dealer
are dedicated to serving your
automotive needs. Your complete
satisfaction is our first priority. Should
you have a problem or concern — either
during or after the warranty period —
please take the following steps to ensure
the quickest possible response:
Step 1
Discuss the situation with a dealership
manager, such as the service manager
or customer relations manager. In most
cases, a satisfactory solution can be
reached at this step.
Step 2
If the dealership does not address your
concern to your satisfaction, call the
Toyota Brand Engagement Center
at (800) 331-4331.
Please have the following information
ready when you call:
• Your Toyota’s vehicle identification number
(located on the driver’s side corner of the
dashboard, under the windshield)
• Current mileage on your vehicle
• Name of your Toyota dealership
A Toyota customer relations representative
will assist you in working with the dealership
to find a satisfactory solution.
Step 3
If your concern has still not been resolved
to your satisfaction, Toyota offers
additional assistance through the Dispute
Settlement Program, a dispute resolution
program administered by the National
Center for Dispute Settlement. The
purpose of the Dispute Settlement
Program is to resolve disputes through
arbitration — a process by which two
parties authorize an independent third
party to hear and resolve a dispute. The
program is informal and free of charge.
To request that your case be reviewed
through the program, complete the
customer claim form in the Owner’s
Warranty Rights Notification booklet
(found in your glove box) and mail it to:
National Center for Dispute Settlement
P.O. Box 515284
Dallas, TX 75251-5284
To initiate arbitration, you must complete
an NCDS customer claim form and mail it
to NCDS. To request a form, call NCDS
at (800) 777-8119 or obtain a copy at
www.ncdsusa.org. When you call,
please have your vehicle identification
number, the current mileage on your
Toyota and the names of your selling and
servicing dealerships.

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.
