Should You Signal or Brake First When Turning in Subject 3?

When turning in Subject 3, you should signal first and then brake. Signaling first is mandatory because traffic laws require the use of turn signals when turning, and you must activate the turn signal at least 50 meters before the intersection to alert vehicles behind you. Therefore, you should signal before slowing down. Additional information about Subject 3 is as follows: 1. Test Content: For large buses, tractors, city buses, medium-sized buses, large trucks, small cars, small automatic transmission cars, low-speed trucks, and small automatic transmission cars for the disabled, the test includes preparation before starting, simulated nighttime lighting test, starting, driving straight, shifting gears, changing lanes, parking by the roadside, going straight through intersections, turning left at intersections, turning right at intersections, crossing pedestrian crossings, passing school zones, passing bus stops, meeting oncoming traffic, overtaking, making U-turns, and nighttime driving. The test content for other permitted vehicle types is determined by the provincial traffic management authorities of the public security department. 2. Large Vehicles: For large buses, tractors, city buses, medium-sized buses, and large trucks, provincial traffic management authorities of the public security department should add complex road driving test content, such as mountainous areas, tunnels, and steep slopes, based on actual conditions.

What to Do When the EA888 Engine Cooling System is Insufficient?

Here is more information about the EA888 engine: 1. The EA888 series engines include two displacements: 1.8L and 2.0L. The 1.8TSI has a maximum power of 118kw at 5000-6200rpm and a maximum torque of 250Nm at 1500-4500rpm. The 2.0TSI can reach a maximum power of 147kw at 5100-6000rpm and a maximum torque of 280Nm at 1700-5000rpm. 2. The mechanical structures of these two displacement engines are basically the same, with the difference lying in the length of the connecting rods between the crankshaft and pistons. The connecting rods of the 2.0TSI are shorter than those of the 1.8TSI, and the crankshaft radius is increased to enhance the displacement.

Can the EA211 spark plug not use double platinum?

EA211 spark plugs can use double platinum. The lifespan of platinum spark plugs is 5 times that of ordinary spark plugs, and the average lifespan of double platinum spark plugs can reach 160,000 kilometers. The following is an introduction to the advantages of double platinum electrode spark plugs: 1. Advantages of platinum electrode spark plugs: (1) Improved ignition performance. (2) Enhanced spark performance. (3) Easily stabilizes within the optimal temperature range between self-cleaning combustion and incandescent combustion. (4) Expanded thermal range. (5) Excellent durability. 2. Types of platinum electrode spark plugs: (1) In terms of materials, they mainly include: nickel alloy, platinum, iridium, etc., all of which have good conductivity. (2) The electrode structures of spark plugs include: single-pole, double-pole, triple-pole, and quadruple-pole, etc.

Why is the steering wheel locked and the key unable to turn?

The steering wheel is locked and the key cannot be turned because the automatic locking function of the steering wheel has been activated. Here are the relevant explanations: 1. Steering wheel anti-theft function: The steering wheel lock is a simple anti-theft feature. When the car is turned off, if the steering wheel is turned left or right or the wheels are not aligned when parked, the force applied can cause the steering wheel to rotate, triggering the self-locking function. Even if the key is inserted and turned with force, it won't move. This is the vehicle's anti-theft system detecting a potential theft risk, thus locking the steering wheel to prevent theft. 2. Solution for a locked steering wheel: First, insert the key and press the brake, then turn the steering wheel left and right. While turning the steering wheel, turn the key to complete the unlocking procedure. If you're not familiar with the process, it might not succeed on the first attempt. Don't worry; simply remove the key and repeat the steps 1-2 times, and you should be able to unlock it successfully.

What Causes the High-Pitched Squealing Sound When Braking?

The reasons for high-pitched squealing sounds when braking: 1. The wear indicator emits a sharp noise as a replacement reminder: Most vehicle braking systems are equipped with a warning mechanism to alert drivers to replace brake pads. When the brake pads wear beyond the designated warning threshold, the wear indicator produces a piercing noise to prompt the owner to inspect or replace the brake pads at a service center. Failure to replace them promptly may result in the metal wear indicator scoring fatal grooves into the brake disc, rendering it unusable. Additionally, excessively worn brake pads can lead to brake failure, potentially causing severe accidents. 2. Severely worn brake discs causing noise: If the brake disc is heavily worn, the outer edge beyond the contact area with the brake pad may develop a raised ridge relative to the friction surface. When the corner of the brake pad rubs against this raised edge of the brake disc, it can generate noise. There are generally two solutions: either have the edges of the brake pads ground down at a service center to avoid contact with the raised disc edge, or opt for a complete brake disc replacement. 3. High-pitched squealing during braking in new vehicles: Many owners assume this indicates a manufacturing defect when they hear sharp noises during braking in new cars. However, this is often part of the break-in process between new brake pads and discs. The noise occurs when braking happens to contact a hard spot in the brake pad material. Applying lubricant at a service center can help reduce this noise.

What are the reasons for the engine fault light in Jetta VS5 to illuminate?

When there is a malfunction in the engine or related components, the engine fault indicator light on the car's dashboard will illuminate, serving as a preventive measure. Generally, the main reasons for the engine fault light to illuminate include the following. 1. Sensor issues: The sensors referred to here include those for coolant temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the car's ECU cannot accurately obtain engine data, leading to the illumination of the engine fault light. 2. Maintenance issues: Poor engine maintenance is the most common cause of the engine fault light illuminating. Vehicles have specific maintenance cycles, and if the owner does not adhere to these schedules, combined with poor driving habits, it will increase the burden on the engine's operation, eventually prompting the fault light to remind the owner to pay attention to the car. 3. Fuel quality issues: The fuel quality mentioned here includes both fuel and engine oil. The fuel added to a car usually has a specific grade, and engine oil can be semi-synthetic or fully synthetic. Manufacturers generally recommend which grade of fuel and type of engine oil to use. If the owner does not follow these recommendations, prolonged use can lead to engine wear. 4. Poor combustion of the air-fuel mixture: Faults in the engine's spark plugs, ignition coils, fuel pump, or clogged fuel lines can all cause poor combustion of the air-fuel mixture. Poor combustion leads to engine carbon buildup or knocking issues, which are eventually detected by the engine's oxygen sensor and reported to the ECU, naturally causing the fault light to illuminate as a warning. 5. Air intake issues: The engine requires air intake during combustion, making the air filter element crucial in this process. If the car's air filter is not clean and not regularly cleaned, it can affect the car's air intake. Over time, this can lead to clogging, and in severe cases, cause the engine fault light to illuminate.
