5-1. Essential Information  
Introduction  
Be careful not to hurt yourself when inspecting your vehicle, replacing  
a tire, or doing some kind of maintenance such as car washing. In par-  
ticular, wear thick work gloves such as cotton gloves when touching  
areas that are difficult to see while inspecting or working on your vehi-  
cle. Doing inspections or procedures with your bare hands could  
cause injury.  
If you are unsure about any procedure this manual describes, we  
strongly urge you to have a reliable and qualified service shop per-  
form the work, preferably your Toyota dealer.  
Factory-trained Toyota technicians and genuine Toyota parts are best  
for your vehicle. Without this expertise and the parts that have been  
designed and made especially for your Toyota, inadequate, incom-  
plete, and insufficient servicing may result in problems. This could  
lead to vehicle damage or an accident and injuries.  
For expert advice and quality service, consult your Toyota dealer.  
To continue warranty eligibility and to protect your investment, it is  
your responsibility to properly maintain your vehicle according to fac-  
tory recommended schedules outlined in this manual. Keep a copy of  
the repair order. It proves that the maintenance that has been per-  
formed is under warranty coverage. If any problem should arise while  
your vehicle is under warranty, your Toyota dealer will promptly take  
care of it.  
This evidence may consist of the following:  
• The Maintenance Log, found within the Warranty and Maintenance  
Guide, must be completely filled out showing mileage, repair order  
number, date for each service, and signed by a qualified automotive  
service technician who service vehicles.  
• Original copies of repair orders or other receipts that include the  
mileage and date the vehicle was serviced. Each receipt should be  
signed by a qualified automotive service technician.  
• For self maintenance, a statement that you completed the mainte-  
nance yourself, displaying mileage and the date the work was per-  
formed. Also, receipts for the replacement parts (fluid, filters, etc.)  
indicating the date and mileage must accompany this statement.

5-1. Essential Information  
Claims against the warranty resulting from lack of maintenance, as  
opposed to defective materials or authorized Toyota workmanship, will  
not be honored.  
Any auto repair shop using parts equivalent to your Toyota’s original  
equipment may perform maintenance. But we recommend that it  
always be done by your Toyota dealer using genuine Toyota parts.  
Selecting “Maintenance Monitor” enables the system to notify you of  
your vehicle’s approaching inspection/servicing period (P. 388).  
The malfunction diagnosis connector is designed exclusively for con-  
necting the specially designed device to perform on-board diagnosis.  
Do not connect any devices other than the specially designed mal-  
function diagnosis devices for servicing. If any device other than the  
malfunction diagnosis device is connected, it may affect the vehicle’s  
electrical devices or lead to damage such as battery depletion.

If you elect to perform maintenance yourself or have your vehicle serviced at  
a location other than your Toyota dealer, Toyota requires that all fluids, parts  
and materials must meet Toyota standards for durability and performance as  
described in this manual.
