Auto Start Stop Switch for Hyundai Santa Fe TM 2019-2020
Eliminate the constant need to manually disable your Hyundai Santa Fe TM’s automatic stop/start function with this direct-fit accessory. Designed specifically for 2019–2020 models that already include a factory start/stop off control, this plug-in module intercepts the original circuit to leave the system disabled by default. After connection, starting the engine automatically defaults to continuous operation, which reduces unnecessary thermal stress on the starter motor, preserves battery charge capacity, and simplifies daily driving. The unit features a durable injection-molded ABS housing and installs directly behind the center console using quick-release wiring and provided trim tools—no cutting, soldering, or ECU programming required. Once plugged into the factory harness, the controller memorizes your preference within three to six seconds of ignition, keeping the dashboard indicator illuminated until you press the toggle once to resume standard OEM behavior. This targeted retrofit delivers consistent cabin comfort while minimizing routine engine wear without altering emissions calibration or safety sensors.
Benefits & Practical Tips
- Extend Component Lifespan: Reducing automatic stop/start cycling decreases wear on starter motors, alternators, and exhaust components while maintaining optimal fluid temperatures.
- Zero-Damage Removal: The supplied soft-plastic pry bars protect interior finishes and keep retaining clips intact during panel disassembly.
- Momentary Override Available: Pressing the original button reactivates factory logic for brief sessions, giving you full control without leaving wires permanently engaged.
