The power source required to start a 2015 Toyota Highlander is a 12-volt automotive battery. This component provides the necessary electrical current to engage the starter motor, which in turn initiates the engine’s combustion process. It also supplies power to various electrical systems when the engine is not running.
Maintaining a functional power source is crucial for the reliable operation of the vehicle. A failing or depleted power source can lead to difficulty starting the engine, unreliable electrical system performance, and potential vehicle breakdowns. Proper battery care and timely replacement contribute to vehicle longevity and driver safety.
