Toyota Maintenance and Repair Support7
TrueStart Batteries
The reputation for quality and reliability was likely a key reason behind your
decision to buy a Toyota. That overall quality is present in each of the compo-
nents of your car or truck, including the battery. When it’s time for a replace-
ment, your Toyota dealer is the only place to find a battery with the power to
start and operate your vehicle like new.
To maintain the original performance designed into your Toyota, a replacement
battery must meet Toyota’s specifications for Cold Cranking Amps (CCA) and
Reserve Capacity (RC). RC, a specification often not met by aftermarket brands,
supplies the power you need during high-demand conditions such as driving in
heavy traffic. RC is also what gives you the powerto operate electronic accessories
with the engine off. By choosing a TrueStart,
™you can be confident your battery
will meet your needs, every day.
Warranty coverage is another important consideration when selecting a battery.
TrueStart
™batteries feature a free replacement period of 24 months or the
remainder of the Toyota New Vehicle Limited Warranty, whichever is longer.
Following the free replacement period, warranty coverage is prorated from
months 25—84 in two simple tiers. See your Toyota dealer for more details.
Don’t entrust your Toyota’s performance to anything less than the best: Genuine
Toyota TrueStart
™Batteries.
WARNING: Battery posts, terminals and related accessories contain lead and
lead compounds, chemicals known to the State of California to cause cancer
and reproductive harm.
Wash hands after handling.

Collision Repair Parts
Insist on Genuine Toyota Quality
If you’re involved in a collision, you wantyour vehicle to be returned to its pre-
accident condition when repaired. To maintain your Toyota’s value, it’s important
to make sure it is repaired with Genuine Toyota Parts. Some repair shops and
insurance companies may suggest using imitation or used salvage parts to save
money. However, these parts do not meetToyota’s high standards for quality, fit
and corrosion resistance. In addition, imitation and used salvage parts are not
covered by any Toyota warranty (see box below).
To maintain the appearance, performance and safety of your Toyota, make sure
only Genuine Toyota Parts are used forcollision repairs. Protect your investment
— insist on Genuine Toyota quality.
Toyota warranty coverage remains intact when vehicle repairs are completed
with Genuine Toyota Parts. Toyota warranties do not cover imitation or used
salvage parts or any damage or failures caused by the use of such parts.
In Case of Accident, Be an Informed Owner
Toyota believes customers have the right to choose the types of parts used in the
repair of their vehicles. That’s why Toyota supports full disclosure by repair shops
and insurance companies regarding parts used for collision repair. The following
information is provided to help you understand the differences in the types of
parts that could be used in the repair of your vehicle.
General Information
“Collision repair parts” or “replacement crash parts” are the parts typically
replaced during the repair of a vehicle that has been damaged in a collision.
These parts include exterior sheet metal such as fenders, hoods, doors and
related components; and plastic components such as bumper covers and
lamp assemblies.

Collision Repair Parts
Warranty Coverage
Warranties for collision repair parts are provided by the manufacturer or distribu-
torof the parts. Warranty coverage varies. Your insurance company or collision
repair facility should provide you with written warranty statements for all parts
used in the repair of your vehicle.
Types of Collision Repair Parts
New original-equipment manufacturer (OEM):Parts that are made by the
vehicle manufacturer or one of its licensees and distributed through its normal
channels. These parts maintain the manufacturer’s vehicle warranty.
Aftermarket or imitation:Parts that are made by companies other than the
vehicle manufacturer or its licensees.
Recycled or used salvage:Used parts and assemblies thathave been removed
from another vehicle. There are no systems in place to regulate the quality or
safety of these parts.
Remanufactured:Parts that have been returned to like-new condition through
repair, refurbishing or rebuilding.
Due to the critical nature of Supplemental Restraint Systems (also known as
air bags), Toyota does not support the use of imitation or used parts for their
repair. Only new Genuine Toyota Parts should be used to repair or replace
Supplemental Restraint Systems.
