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.

MAINTENANCE
You are responsible for performance   
of the required maintenance indicated   
in the Owner’s  Manual and this booklet. 
Toyota will not deny a warranty claim   
solely because you do not have records 
to show that you maintained your vehicle. 
However, any failure or noncompliance   
caused by lack of maintenance is not   
covered by this warranty.
When maintenance and repairs are 
paid for by you, these 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,   
any failure or noncompliance caused by 
improper maintenance or repairs is not 
covered by this warranty.
*   Warranted until first required maintenance under terms of the California Emission Control Warranty.  
8/80 = Covered for eight years or 80,000 miles, whichever occurs first.

YOUR WARRANTY RIGHTS   
AND OBLIGATIONS
The California Air Resources Board (CARB) 
and Toyota are pleased to explain the 
emission control system warranty for your 
2020 vehicle. In California, new motor   
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.
