TSB: A battery in a stored vehicle is subject to conditions that can reduce its performance and service
life. These conditions include storage period, temperature, parasitic drain, and battery load.
Because of these factors, battery inspection and maintenance are required in order to ensure
proper operation and optimal battery life.
As a matter of policy, Toyota does not provide battery warranty coverage for discharged and/or
failed batteries due to lack of maintenance. It is the dealer?s responsibility to maintain the specified
State-Of-Charge (SOC) of the vehicle?s battery while in stock and ensure proper SOC at delivery.
To eliminate customer service concerns due to an undercharged battery during the first few weeks
of ownership, ALL dealers should check battery SOC and recharge, if necessary, no more
than 48 hours before delivery to the customer.
