Lincoln Lincoln Aviator 2020-present Electrical Specifications

The 2020-Present Lincoln Aviator features a 12-volt electrical system with a lithium-ion battery for hybrid models. It supports advanced electrical components, including a 10.1-inch touchscreen, wireless charging, and a 28-speaker Revel Ultima 3D audio system. The hybrid variant includes a 13.6 kWh battery pack, providing an electric-only range of up to 21 miles. The system is compatible with Lincoln's SYNC 3 infotainment platform and supports over-the-air updates.

Regular maintenance includes checking the battery terminals for corrosion, ensuring proper charging system function, and inspecting wiring for wear. Hybrid models require periodic checks of the high-voltage battery cooling system and software updates. Lincoln recommends a professional inspection every 10,000 miles or annually, whichever comes first, to maintain optimal performance and safety.

To replace the 12-volt battery, first, disconnect the negative terminal, followed by the positive terminal. Remove the battery hold-down clamp and carefully lift the battery out. Install the new battery, secure it with the clamp, and reconnect the terminals in reverse order. For hybrid models, high-voltage battery replacement must be performed by a certified technician due to safety risks.

If you experience electrical issues, check the battery connections and fuses first. Use the vehicle's diagnostic system to identify error codes. Common problems include dead batteries, blown fuses, or software glitches. For persistent issues, consult a Lincoln-certified technician to avoid further damage to the electrical system.

To optimize performance, keep the battery charged and avoid draining it excessively. Regularly update the SYNC 3 software and ensure all electrical components are functioning correctly. For hybrid models, use the EV Coach feature to maximize electric-only driving. Avoid overloading the system with aftermarket accessories that exceed the vehicle's electrical capacity.
