The spark plugs of the Tiguan 1.8T should be replaced every 20,000 kilometers. The function of the spark plugs is to discharge the pulse high voltage sent by the high-voltage wire, break down the air between the two electrodes of the spark plug, and generate an electric spark to ignite the mixed gas in the cylinder. Taking the 2019 Tiguan 4WD Chuangrui model as an example, its body dimensions are: length 4486mm, width 1839mm, height 1657mm, wheelbase 2681mm, and fuel tank capacity 60L. The 2019 Tiguan 4WD Chuangrui model is equipped with a 2.0L turbocharged engine, with a maximum power of 132kW and a maximum power speed of 4000 to 6000 rpm. It is matched with a 7-speed dual-clutch transmission.

Should You Press the Brake When Starting the Engine?

For automatic transmission vehicles, you need to press the brake when starting the engine. For manual transmission vehicles, you should press the clutch to start. Some manual cars can be started directly by turning the key without pressing the brake or clutch if they are in neutral. Benefits of pressing the brake when starting: 1. Enhanced braking: Pressing the brake helps improve the vehicle's braking capability. Some parking slopes are too steep, requiring the use of the handbrake + gear method. If you press the clutch when starting, the car might roll due to insufficient handbrake effectiveness. Pressing the brake at this moment can prevent rolling. 2. Preventing accidents: It avoids situations where you forget to park in gear and start without pressing the clutch, which could cause the car to lurch forward and lead to an accident. Pressing the brake when starting in gear can instantly stall the engine, preventing accidents.

What does independent lane change mean in Subject 3?

Independent lane change refers to the driver selecting an appropriate lane to change to and choosing the most reasonable lane for driving. Below are detailed explanations about independent lane change: 1. Lane change method: Pay close attention when changing lanes and turning, avoid arbitrary turns and lane changes. Before turning, always observe the situation in the rearview mirror in advance, and try to understand the conditions on both sides and behind the vehicle as much as possible. Do not make any turns arbitrarily without clearly seeing the rearview mirror. 2. Precautions: Turn on the turn signal and honk the horn in advance when turning or changing lanes, try to move to the side as early as possible, and turn smoothly. Always slow down in advance and yield to vehicles and pedestrians going straight when entering or exiting non-motorized lanes. 3. Careful observation: Slow down and wait before exiting a gate or turning from a small road onto a main road, and always observe the road conditions on both sides clearly.
