16Your Warranties in Detail
WARRANTY
Gradual Capacity Reduction
of Traction Battery
(Lithium-ion Battery)
Lithium-ion battery capacity (the ability to
hold a charge) gradually reduces with time
and use. This is a natural characteristic of
lithium-ion batteries. The extent at which
capacity is reduced changes drastically
depending on the environment (ambient
temperature, etc.) and usage conditions such
as how the vehicle is driven and how the
lithium-ion battery is charged. Reduction of
lithium-ion battery capacity is NOT covered
under warranty. In order to lessen the
possibility of capacity reduction, follow the
directions listed in the Owner’s Manual under
“Capacity Reduction of the Hybrid Battery
(Traction Battery).”
Maintenance Expense
Normal maintenance services such as:
• Engine tune-ups
• Replacement of fluids and filters
• Lubrication
• Cleaning and polishing
• Replacement of spark plugs and fuses
• Replacement of worn wiper blades, brake
pads/linings and clutch linings
Vehicles with Altered Odometer
Failure of a vehicle on which the odometer
has been altered so that actual vehicle
mileage cannot be readily determined.



Salvage or Total-Loss Vehicles
Any vehicle that has ever been branded as
salvage, total loss, true mileage unknown or
similar title under any state’s law or has ever
been declared a “total loss” or equivalent by
a nancial institution or insurer, such as by
payment for a claim in lieu of repairs because
the cost of repairs exceeded the cash value
of the vehicle. This exclusion does not apply
to the emission control warranties, including
Emission Control Warranty Enhancements or
any open Safety Recalls/SSCs/LSCs.
Incidental Damages
Incidental or consequential damages
associated with a vehicle failure. Such
damages include but are not limited to
inconvenience; the cost of transportation,
telephone calls and lodging; the loss of
personal or commercial property; and the
loss of pay or revenue.
Disclaimer of Extra
Expenses and Damages
The performance of necessary repairs
and adjustments is the exclusive remedy
under this warranty or any implied
warranty. Toyota does not authorize
any person to create for it any other
obligation or liability in connection with
this vehicle. Toyota shall not be liable
for incidental or consequential damages
resulting from breach of this written
warranty or any implied warranty. Any
implied warranty of merchantability or
tness for a particular purpose is limited
to the duration of this written warranty,
except in states where this limitation
is not allowed.
