Even when you’re not driving Model S, the Battery discharges very slowly to power the onboard electronics. On average, the Battery discharges at a rate of 1% per day. Situations can arise in which you must leave Model S unplugged for an extended period of time (for example, at an airport when travelling). In these situations, keep the 1% in mind to ensure that you leave the Battery with a sufficient charge level. For example, over a twoweek period (14 days), the Battery discharges by approximately 14%. Discharging the Battery to 0% may permanently damage the Battery. To protect against a complete discharge, Model S enters a low-power consumption mode when the charge level drops to 5%. In this mode, the Battery stops supporting the onboard electronics to slow the discharge rate to approximately 4% per month. Once this low-power consumption mode is active, it’s important to plug in Model S within two months to avoid Battery damage. NOTE: When the low-power consumption mode is active, the auxiliary 12V battery is no longer being charged and can completely discharge within 12 hours. In the unlikely event this occurs, you may need to “jump start” or replace the 12V battery before you can charge. In this situation, contact
