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)

emission control system warranty for your 
2021 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

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.
