What do the + and - signs next to the D gear in an automatic transmission mean?

Automatic transmission D gear next to the + and - refers to the upshift and downshift, D gear refers to the manual mode of the automatic manual transmission, which can be used to manually control the upshift and downshift of the transmission, when using the D gear does not need to step on the brake or release the throttle. The characteristics of using the D gear of the automatic transmission are: 1. You can get a larger traction force when overtaking; 2. You can get a larger power when going up a long slope; 3. You can use the engine brake to control the speed when going down a long slope to prevent the brake from overheating. The other gears of the automatic manual transmission are: 1. P refers to the parking gear; 2. R refers to the reverse gear; 3. N refers to the neutral gear; 4. S refers to the sport gear; 5. L refers to the low gear.

What Causes Abnormal Noises When the Car Air Conditioner is On?

The air conditioning system adjusts and controls the temperature, humidity, air cleanliness, and airflow inside the car cabin to a suitable state, providing a comfortable environment for passengers, reducing fatigue during travel, and creating favorable working conditions for the driver. It is a crucial ventilation device for ensuring safe driving. The reasons for abnormal noises when the car air conditioner is on include: 1. Damaged compressor belt tensioner; 2. Excessive wear or damage to the blower motor; 3. Malfunction of the air recirculation motor; 4. High pressure in the air conditioning system; 5. Incomplete engagement of the compressor clutch; 6. Prolonged non-replacement of the air filter. Solutions for abnormal noises when the car air conditioner is on: 1. Clean the air conditioner vents promptly; 2. Remove the fan blades to add lubricant and clear any foreign objects; 3. Replace the blower with a new one; 4. Replace the air filter.

How often should the brake fluid of the Tiguan be replaced?

The maintenance manual for the Tiguan specifies that the brake fluid should be replaced every 35,000 kilometers or 48 months. Precautions for using brake fluid are as follows: 1. Do not mix different types or brands of brake fluid, as differing formulations can reduce the performance of the brake fluid. 2. Replace or filter the brake fluid promptly if it absorbs moisture or contains impurities, as this can lead to insufficient braking pressure and affect braking performance. 3. If the vehicle has been driven for 40,000 kilometers or the brake fluid has been in continuous use for over 2 years, it may deteriorate due to prolonged use and should be replaced immediately. 4. If the braking feels inconsistent during normal driving, replace the brake fluid promptly. Before replacement, clean the braking system thoroughly with alcohol. 5. If the vehicle pulls to one side during braking, conduct a comprehensive inspection of the braking system. If the brake cylinder cups are found to be excessively swollen, this may indicate poor-quality brake fluid. In such cases, replace the brake fluid with a higher-quality product and also replace the cups.

What is the device that can reduce nitrogen oxide emissions from the engine?

The device that can reduce nitrogen oxide emissions from the engine is the Exhaust Gas Recirculation (EGR) system. Exhaust Gas Recirculation is a technology used in small internal combustion engines for automobiles, where a portion of the exhaust gases is redirected back to the intake side to be re-breathed after combustion. There are various forms and control methods for EGR systems. Based on the actuator control form, they can be categorized into mechanically controlled EGR systems and electronically controlled EGR systems. The basic principle of Exhaust Gas Recirculation: Since the specific heat of triatomic gases such as CO2, H2O, and NO2 in engine exhaust is relatively high, when fresh air-fuel mixture is mixed with exhaust gases, the heat capacity increases accordingly. Heating this exhaust-diluted mixture requires more heat to raise the temperature by 1 degree, which means that with the same total heat release from fuel combustion, the maximum combustion temperature is reduced. Additionally, the dilution effect of exhaust gases on the fresh air-fuel mixture lowers the oxygen concentration, thereby inhibiting the formation of nitrogen oxides.

What is the difference between static water submersion and dynamic water submersion?

Water-damaged vehicles can generally be divided into two categories: dynamic water submersion and static water submersion. This is actually quite easy to understand. Dynamic water submersion refers to a vehicle being submerged while in motion, whereas static water submersion occurs when the vehicle is parked. The main difference between the two, from an insurance company's perspective, lies in whether engine damage is involved. Engine damage: Under normal circumstances, static water submersion does not cause engine damage. For dynamic water submersion, it's difficult to determine whether the engine will be damaged—it might or might not be. However, if the engine is forcibly started while submerged, it will almost certainly be damaged. This raises the issue of insurance claims. If you have purchased water submersion insurance, the engine damage can generally be covered regardless of whether it was a secondary start or any other scenario, unless it was done intentionally. Therefore, claims that "secondary starts" void engine coverage even with water submersion insurance are either unprofessional or an excuse used by insurers to avoid paying. However, without water submersion insurance, engine damage will not be covered under any circumstances of water submersion.

How many points are deducted for the rearview mirror crossing the line during the reverse parking in Driving Test Subject 2?

This situation will result in a deduction of 100 points. Deduction items for reverse parking in Subject 2: 1. Not following the specified route or sequence: 100 points deducted. 2. Vehicle body crossing the line: 100 points deducted. 3. Failing to complete the reverse parking: 100 points deducted. 4. Stopping midway: 100 points deducted. Extended information on reverse parking operation techniques: Learn to observe and accurately use the rearview mirrors: These include the left and right rearview mirrors and the interior rearview mirror. After the driver sits in the vehicle, their field of vision is obstructed, so it is necessary to use the rearview mirrors to expand the field of vision. The left and right rearview mirrors are mainly used to observe the situation around the vehicle body and the road conditions, while the interior rearview mirror is primarily for observing the situation behind the vehicle. During reverse parking operations, the left and right rearview mirrors are used most frequently.
