Precautions for replacing the battery in the Tiguan: 1. During disassembly, remove the negative terminal first, then the positive terminal; during installation, connect the positive terminal first, then the negative terminal to avoid short circuits. 2. When disconnecting the battery's positive and negative terminals, ensure the grounding wires do not touch any metal parts. 3. After installing the new battery, start the car and then turn it off, wait for ten minutes, and check if the vehicle operates normally. The Tiguan is a compact SUV under SAIC Volkswagen, with dimensions of 4506mm in length, 1809mm in width, and 1685mm in height, and a wheelbase of 2684mm. The Tiguan features front-wheel drive, a front MacPherson strut independent suspension, a rear multi-link independent suspension, and electronic power steering.
When replacing the battery in my Tiguan, as a seasoned driver who has owned this car for years, I've summarized some key insights. First and foremost, safety is paramount: the engine must be turned off, the key removed, and all electronic devices such as lights and air conditioning switched off to prevent electric shock or short circuits. Before starting, wear gloves and use insulated tools. The order of disconnecting the battery is crucial—first the negative terminal (black cable), then the positive (red cable)—to avoid spark risks. When installing the new battery, reverse the order: connect the positive cable first, then the negative. Choosing the right battery requires checking the manual for matching specifications, ensuring correct capacity and voltage (e.g., a common 12V 70Ah battery). A mismatch can lead to starting difficulties or electrical damage. Modern Tiguans have many electronic systems, and you may lose ECU settings like radio presets or window calibration, so using a backup power supply to temporarily maintain data is advisable. After installation, check that the terminals are securely fastened to prevent future issues. Finally, start the car to ensure everything works properly. Regular battery health checks can prevent unexpected failures.
