How to Solve the Issue of Nissan Sunny Consuming 10L/100km?

Here are the solutions for the Nissan Sunny consuming 10L/100km: 1. Tires: Fuel consumption is significantly related to tires. Generally, the larger the contact area between the tires and the ground, the stronger the grip. However, this also means greater frictional resistance. 2. Oxygen Sensor: The primary function of the oxygen sensor is to monitor the oxygen concentration in the exhaust. The vehicle's computer adjusts the fuel injection quantity in real-time based on the data it provides. It is usually installed near the three-way catalytic converter, divided into the front oxygen sensor and the rear oxygen sensor. 3. Carbon Deposit Issue: Carbon deposits inside the engine can cause unstable idle vibrations and reduced machine efficiency, leading to increased fuel consumption. Carbon deposits mainly adhere to areas such as the intake tract, intake and exhaust valves, piston tops, spark plugs, fuel injectors, and throttle valves. 4. Poor Driving Habits and Road Conditions: Poor driving habits are also a reason for increased fuel consumption. Examples include sudden acceleration, sudden braking, sudden stops, prolonged idling, speeding, frequent lane changes; for manual transmission vehicles, delayed gear shifting, and driving at high speeds in low gears, etc.

Can I go at 9 o'clock for the 8 o'clock session of Subject 3?

It's best to go early. If you're late and the first batch of people have already entered, you won't be allowed in. This will be counted as an absence and treated the same as failing the exam, so be sure to arrive early. The content of the Subject 3 exam includes the road driving skills test and the safety and civilized driving knowledge test. It is part of the motor vehicle driver's license assessment and is the abbreviation for the road driving skills and safety and civilized driving knowledge test subjects in the motor vehicle driver's exam. The content of the road driving skills test varies depending on the type of vehicle you are licensed to drive. Additional information is as follows: 1. Road driving skills test content: preparation before getting on the car, simulated lighting test, starting, driving in a straight line, shifting gears, changing lanes, parking by the roadside, going straight through intersections, turning left at intersections, turning right at intersections, passing through crosswalks, passing through school zones, passing through bus stops, meeting vehicles, overtaking, making U-turns, and driving at night. 2. Safety and civilized driving knowledge test content: requirements for safe and civilized driving operations, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations such as tire blowouts, and post-accident handling knowledge.

What to Do If You Fail the First Attempt at Subject One?

You can apply for an immediate make-up test. Each subject allows one examination attempt, and if you fail, you can retake it once. If you do not participate in the make-up test or fail it again, the current examination process will be terminated, and the applicant must reschedule the test. However, for Subject Two and Subject Three, the rescheduling must be done at least ten days later. If you fail the Subject Three safety and civilized driving knowledge test, the passed road driving skills test scores remain valid. Below is an introduction to the relevant content of Subject One: 1. Test Content: The test includes theoretical driving knowledge, road safety laws and regulations, local regulations, and other related knowledge. 2. Alternative Name: Subject One is also known as the theoretical driving test or driver theory test. 3. Test Format: The test is computer-based and conducted at the vehicle management office. The question bank consists of 1,229 questions, from which 100 questions are randomly selected in a specified proportion. 4. Question Types: The questions are divided into single-choice and true/false questions, with a full score of 100, and passing requires a score of 90 or above.

Is it not necessary to wait for the traffic light when turning right?

Whether you need to wait for the red light when turning right depends on the situation. At intersections with circular signal lights or without any auxiliary signs, you do not need to wait for the red light to turn right. However, if the signal light is an arrow type, you must wait for the red light to turn right. When making a right turn, vehicles must drive in the right-turn lane. If you turn right from a straight or left-turn lane, it will increase traffic congestion and may result in penalties from law enforcement for running a red light. How to identify the right-turn lane: Look for the overhead lane signs at the intersection, which are placed high for visibility from a distance, allowing you to change lanes in advance. Alternatively, check the road markings to find the lane marked for right turns. Precautions for right turns: One easily overlooked violation during a right turn is failing to yield to pedestrians. If pedestrians are crossing the road while you are turning right, you must stop and wait; otherwise, you may face fines. Additionally, if a left-turning vehicle is approaching while you are turning right, you must yield to it. In case of a collision, the right-turning vehicle bears greater responsibility.

How to Pass the School Zone in Subject 3 of the Driving Test?

In the school zone section of Subject 3, you need to apply the tap-braking technique. Similar to bus stops, your speed should be below 30 km/h when passing through. You must tap the brake to slow down, and if you encounter students crossing the road after school, you should stop and wait. Here are the key points requiring tap-braking in Subject 3: 1. Straight through intersections: Due to complex traffic conditions with potential vehicles or pedestrians, you must tap the brake in advance to reduce speed below 30 km/h, even when the light is green with no obstacles. Failure to do so will result in immediate failure. 2. Left/right turns: Always signal first, then decelerate (even if moving slowly, tap the brake before turning). 3. Bus stops: Normally announced by voice prompt; if not, watch for roadside signs. Tap brake and pass slowly. 4. Pedestrian crossings: Mandatory brake tap. Stop completely if pedestrians are crossing (never stop ON the crosswalk). Avoid honking or rushing - such behavior means instant failure. 5. School zones: Same as bus stops - below 30 km/h with brake taps. Stop for crossing students. 6. U-turns: Always decelerate, potentially shifting to 1st/2nd gear. High-speed turns compromise vehicle stability. 7. Oncoming traffic: Slow down when meeting vehicles. Follow system instructions - even without actual vehicles, execute the slowdown procedure when prompted.

Can Halogen Headlights Be Replaced with LED?

Halogen headlights can be replaced with LED headlights. Below is more information about these two types of headlights: 1. Halogen lights are based on incandescent bulbs filled with inert gas to extend the filament's lifespan. The light emission of halogen lamps involves three physical processes: electrical energy—thermal energy—light energy, resulting in relatively high energy consumption. Halogen lights emit yellow light. 2. LED lights can directly emit red, yellow, blue, green, cyan, orange, purple, white, and other colors of light. Also known as light-emitting diodes, LEDs can convert electrical energy directly into light energy, achieving an energy conversion efficiency of up to 90%. White light is typically used in automotive applications.
