I've been driving for over a decade and have encountered three instances of battery depletion. Personally, I feel that the battery is basically useless at this point and it's best not to use it anymore. The battery is the lifeblood of a car. Each time it's depleted, the internal chemical materials suffer damage. After three times, its energy storage capacity is greatly reduced, making it prone to failure during startup or even stalling midway, especially noticeable in winter. I've tried recharging the battery, but it would deplete again shortly after, ultimately wasting money and causing inconvenience. Later, I had it checked at a repair shop, and the mechanic said both the voltage and internal resistance exceeded the standards, so I replaced it with a new one. After the replacement, the car starts much more smoothly, and it's been worry-free. For regular maintenance, remember to periodically check the battery's condition. Reducing the number of depletion instances can extend its lifespan—safety first.

How to turn on the heating function in the Tiguan L's air conditioning system?

Tiguan L air conditioning heating steps: Locate the temperature control switch on the air conditioning control panel; Adjust the temperature to the highest setting to activate heating; Find the airflow control knob and select an appropriate fan speed. Note that you don't need to press the AC button when using the heating function, as the AC button is the cooling switch for the car's air conditioning system. The compressor does not need to operate during heating. The Tiguan L's air conditioning system utilizes engine heat for warming. During heating, high-temperature coolant from the engine flows through the heater core, while the blower forces air to pass through this core, allowing warm air to be discharged from the air vents.

Lightly press the accelerator: The car consumes the most fuel during low-speed starts, so gently pressing the accelerator when starting can prevent excessively high RPM and effectively reduce fuel consumption. 2. Avoid high RPM: Try to avoid unnecessary high RPM as fluctuating engine speeds can significantly increase fuel consumption. 3. Regular maintenance: Change the engine oil and remove carbon deposits. 4. Avoid emergency braking: Anticipating road conditions in advance not only improves driving safety but also saves fuel, such as gradually slowing down before traffic lights and using inertia to coast.

What type of suspension does the Tiguan use?

The Tiguan adopts a front MacPherson strut independent suspension and a rear multi-link independent suspension. This design is more inclined towards urban road conditions and passenger comfort. Most rear suspensions of the Tiguan use multi-link independent suspension, which can improve the wheel's ground contact performance, thereby enhancing the vehicle's handling and grip. Common suspension types used in vehicles include independent and non-independent suspensions. Independent suspensions include MacPherson strut, multi-link, double-wishbone, double A-arm, and double ball joint suspensions. Non-independent suspensions include torsion beam and solid axle suspensions. Most vehicles with MacPherson strut front suspensions are typically those with transversely mounted engines, as transversely mounted engine vehicles usually do not have sufficient space in the front to accommodate double-wishbone suspensions.
