How to Determine if the Car is Turned Off?

1 Answers

The most intuitive method is to check the dashboard. If the battery indicator light and the engine fault light on the dashboard are illuminated, it is likely that the vehicle is turned off. If you are unsure whether the car is turned off, gently press the accelerator with your foot. If you can hear a noticeable increase in RPM, it means the engine is still running. If there is no response, then restart the car. Apart from keyless start models, you can also check the position of the key.

What are the reasons for slow acceleration and insufficient power in the Tiguan?

The following are the reasons for slow acceleration and insufficient power in a car: 1. Engine fuel system: This is a common problem area in cars. Clogged fuel injectors, fuel line leaks, reduced fuel pump power, or a blocked fuel filter can all cause a car to lack power when going uphill. The feeling of powerlessness in a car is mainly due to insufficient fuel supply to the engine during uphill driving, leading to decreased combustion efficiency and failure to meet the required horsepower. 2. Intake system: In addition to fuel, the engine also needs air. If components such as the air filter or throttle valve are clogged, resulting in insufficient air intake, it can also cause the car to accelerate poorly and have slow acceleration. 3. Spark plugs: If the spark plugs have poor ignition, it may lead to issues with poor acceleration.

What is the optimal temperature for car air conditioning?

The temperature difference between the car interior and the external environment should not be too large, as it may cause discomfort. Generally, it is recommended to maintain a temperature difference within 10°C for passenger cars and 8-12°C for large buses. The car air conditioning temperature can be adjusted according to the season, with specific recommendations as follows: 1. In summer, set the air conditioning to 21-25°C. 2. In winter, set the air conditioning to 25-28°C. Additional information about car air conditioning includes: 1. Car air conditioning: This refers to the air conditioning system installed in vehicles, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. 2. Components: The system includes refrigeration units, heating units, and ventilation units, all of which are designed to make efficient use of the limited space inside the car.

What is the reason for one fan turning and the other not in the Tiguan?

Tiguan fan one turns and the other does not turn reasons: 1. Inaccurate water temperature: Most car radiator fans nowadays operate electronically based on temperature control, so generally, the fan will only start turning normally when the car's internal water temperature reaches the required level. If the temperature is too low, the radiator fan will not turn. Therefore, when the car radiator fan fails to turn, the first thing to check is whether the water temperature meets the requirements. 2. Relay failure: If the water temperature meets the requirements but the car radiator fan still does not work, the issue might be with the fan's relay. If the relay is faulty, the car's radiator fan will not function. 3. Thermostat switch problem: If there are no issues with the above two aspects, then it is necessary to check the thermostat switch. This component can sometimes develop faults, which can also affect the operation of the car radiator fan, so it should also be inspected carefully.

Is Automotive Urea Harmful to Humans?

Automotive urea is not harmful to humans. Here is an introduction to automotive urea: 1. Properties: Urea aqueous solution is a high-purity transparent liquid with a faint ammonia odor. Although it is alkaline, it is non-toxic. The SCR solution has obvious advantages in the National IV diesel vehicle exhaust emission treatment system, and automotive urea is an essential additive for the SCR solution. With the gradual implementation of the National IV emission standard for diesel vehicles in various cities, the demand for automotive urea may surge. 2. Categories: Automotive urea includes the urea tank (loaded with diesel exhaust fluid) and the SCR catalytic reaction tank. The operation process of the SCR system is as follows: when nitrogen oxides are detected in the exhaust pipe, the urea tank automatically sprays diesel exhaust fluid. The diesel exhaust fluid and nitrogen oxides undergo a redox reaction in the SCR catalytic reaction tank, producing non-polluting nitrogen and water vapor for discharge.

What Causes the Dashboard Lights to Flicker in the Tiguan?

Tiguan dashboard light flickering is generally caused by an issue with the fuel emission system. When the warning light comes on, you should start the car, turn it off, start it again, turn it off, and repeat this process three times, then observe whether the warning light remains on. If it still stays on, you should take the car to a 4S shop for inspection and repair. Below is an introduction to the dashboard: 1. Basic Introduction: The instrument panels of different cars vary. However, conventional car instrument panels typically include a speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, and charging gauge. 2. Speedometer and Odometer: The speedometer and odometer are actually composed of two gauges. One is the speedometer, and the other is the odometer. 3. Fuel Gauge: There are two coils inside the fuel gauge. They are located on the "F" and "E" sides respectively, and the sensor is a variable resistor controlled by the float height.
