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.
