Why Won't My Jetta Start?

[ElijahLee]

Jetta won't start due to a dead battery or incorrect gear position. Below are the specific reasons why a Jetta won't start: Dead battery: This could be caused by leaving headlights on for an extended period leading to battery drain, or the battery may have reached the end of its lifespan. It's generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also cause vehicle electrical circuit failures. Checking for a dead battery is simple - just press the horn to test. Incorrect gear position: For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) position when starting. If placed in R (Reverse) or D (Drive), the car won't start. Some manual transmission vehicles also won't start if the clutch isn't depressed.
