THE NEW WORLD OF
ANTI-THEFT TECHNOLOGY
This Toyota vehicle is equipped with an
electronic “immobilizer” anti-theft system.
The vehicle’s immobilizer system prevents
the fuel cell system from operating if a
Smart key that has been previously
registered with the vehicle’s on-board
computer is not detected. While an exact
mechanical key will open the door and
allow retrieval of items locked in the
vehicle, it won’t READY-ON/start the
vehicle.
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.

the quality and reliability of our
products was a key factor in
your decision to buy a Toyota. We also
know how disruptive the loss of
transportation can be to your daily routine.
That’s why we’re pleased to offer you the
benefits of our Transportation Assistance
Policy.
Under this policy, you are eligible for
transportation assistance if your Toyota
must be kept overnight for
warranty-covered repairs. The policy
applies when your vehicle must be kept
overnight for any of the following reasons:
•The warranty repairs will take longer
than one day to complete.
•The warrantable condition requires
extensive diagnosis.
•The parts needed for the warranty
repairs are not readily available and
your vehicle is inoperative or unsafe to
drive. The policy does not apply when warranty
repairs can be completed in one day but
the vehicle must be kept overnight due to
dealer or owner scheduling conflicts.
The Transportation Assistance Policy
applies for the duration of the New Vehicle
Limited Warranty. The policy applies to all
2017 model-year Toyotas sold and
serviced by authorized Toyota dealerships
in the mainland United States and Alaska.
For further details, please consult your
Toyota dealer.

irai.00505-17WMG-MIR_/TS_Warr_Maint_v1
REPLACING THE KEY
Upon purchase, each vehicle should have
two Smart master keys and an aluminum
tag with a key-code imprinted on it. To
generate a fully functional replacement
Smart key (one that will both open the
doors and READY-ON/start the vehicle),
one of the Smart master keys is required.
To make a mechanical key that will open
the door for retrieval of items locked
inside the vehicle, the aluminum key-code
tag can be used. If a Smart 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 Smart 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.
