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 test the auxiliary (12V) battery and recharge, if necessary, no more than 48 hours before delivery to the customer.
