Can an automatic transmission car coast in neutral when going downhill?

Will the right or wrong be displayed during the subject one exam?

During the subject one exam, the right or wrong will be displayed, but there will be no answer hints. Additional information is as follows: 1. Subject one exam: The total time is 45 minutes. The test paper consists of 100 questions, including true or false and multiple-choice questions, with a full score of 100 points and a passing score of 90. The test paper is randomly selected and combined by the computer driver examination system according to the proportion specified in the "Motor Vehicle Driver's License Work Regulations". The questions are randomly selected by the computer from the question bank to form a set of 100 questions. Candidates select answers based on the questions and click submit after completion, with no modifications allowed. If the answer is wrong, the computer will directly display the correct answer for the previous question when moving to the next question, but it will not show the correct answer. 2. Notes: If you answer 10 questions incorrectly (i.e., deduct 10 points), the computer will automatically prompt the end of the exam and will not allow further answers. Therefore, candidates must carefully check and repeatedly confirm their answers during the exam to ensure they select the correct answers before submitting.

What Happens If a Car Lacks Antifreeze?

If a car lacks antifreeze, the antifreeze cannot circulate properly, the engine cannot dissipate heat normally, and the engine temperature will become excessively high. In severe cases, this can lead to engine damage. The functions of antifreeze: Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and offering year-round protection against scale and corrosion. Can different antifreeze brands be mixed? It is necessary to use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas. If mixed, chemical reactions between the additives may occur, rendering them ineffective. How to choose antifreeze: The basic indicators of antifreeze are its freezing point and boiling point. On the market, antifreeze is available in several specifications with freezing points such as -15°C, -25°C, -30°C, and -40°C. Generally, it is advisable to choose one with a freezing point at least 10°C lower than the lowest temperature in your region.

How to Shift a Serpentine Gear?

Shifting methods for serpentine gears are as follows: 1. P gear: Parking gear, used when the vehicle is parked for a long time. It locks the rotating parts of the car with a mechanical device inside the transmission to prevent the car from moving. The operation method is: pull up the handbrake, then shift into P gear; 2. R gear: Reverse gear, used when the vehicle needs to move backward. The operation method is: press the brake, press the shift lock on the shift lever, then move the shift lever to R gear; 3. N gear: Neutral gear, used when the vehicle is parked for a short time without turning off the engine. After shifting into N gear, the engine's power will not be transmitted to the wheels, and pressing the accelerator will not make the vehicle move; 4. S gear: Represents sport mode, making the vehicle drive more sporty. When the shift lever is shifted into S gear, the throttle response speed becomes faster, the engine speed will also be maintained in a higher speed range, and the shift timing is delayed, keeping the vehicle in a high-power output state at all times.

What is an Automotive ECU?

Automotive ECU is the engine control unit. The ECU control unit makes adjustments to the vehicle's operating system by comprehensively analyzing driving data such as vehicle speed, engine RPM, and transmission gear position. Introduction to ECU: The ECU is referred to as the brain of the engine. During engine operation, the ECU collects data, processes it, and then controls the engine's operation through control mechanisms. Engine sensors transmit data to the ECU, which processes the information and adjusts the engine's operating state through actuators. The ECU is typically installed in the engine compartment. Functions of ECU: The primary role of the electronic control unit is to compute, process, and judge information input from sensors like the air flow meter, based on its stored programs and data, then output commands to provide the fuel injector with electrical pulse signals of a certain width to control fuel injection volume. The electronic control unit consists of a microcomputer, input/output circuits, and control circuits. Capabilities of ECU: ECUs generally feature self-diagnosis and protective functions. When a system fault occurs, it automatically records the fault code in RAM and implements protective measures by reading substitute programs from the inherent programs mentioned above to keep the engine running. Simultaneously, these fault messages are displayed on the dashboard and remain illuminated, allowing the car owner to promptly identify issues and drive the vehicle to a repair shop.

What time does the first session of Subject 2 in the morning start?

Subject 2 is divided into two exam sessions: morning and afternoon. The first session (morning session) is scheduled from 8:00 AM to 12:00 PM. The second session of Subject 2 is from 1:00 PM to 6:00 PM (Note: Exam schedules may vary by region. The above times are for reference only. Please confirm the actual schedule with your local test center or consult your instructor). Additional information: 1. Subject 2: The on-site driving skills test, also known as Subject 2, requires candidates to master basic methods of driving on-site and on internal roads, properly use vehicle controls, accurately control the vehicle's spatial position, and precisely manage the vehicle's movement, speed, and route. 2. Important Notes: There is no overall time limit for Subject 2, but the reverse parking (backing into a garage) must be completed within 210 seconds (starting from engaging reverse gear), otherwise, it will be considered a failure. Parallel parking must be completed within 90 seconds, or it will be deemed a failure. For the hill start, you must start moving uphill within 30 seconds after stopping.

How many seconds does the GTR take to accelerate from 0 to 100 km/h?

GTR's 0-100 km/h acceleration time is 2.8 seconds, while the 2014 model takes 2.7 seconds. Below are the relevant details: 1. 2014 Model: The most significant change in the new car is the reduction of the 0-100 km/h acceleration time by 0.1 second, now at 2.7 seconds. This improvement is mainly due to the reduced drag coefficient and enhanced power tuning. The 2014 GT-R still features the 3.8T V6 engine from the current model, with slightly improved power parameters. The maximum power output is 553 horsepower, an increase of 13 horsepower over the previous model, while the peak torque remains at 628 N·m. 2. Black Diamond Edition: The Black Diamond Edition is equipped with RAYS forged ultra-lightweight 6-spoke black aluminum alloy wheels, a unique red and black interior, RECARO leather racing seats, and a carbon fiber rear wing. The Nissan GT-R Black Diamond Edition still comes with a 3.8-liter twin-turbocharged engine, delivering a maximum output of 550 horsepower and a peak torque of 632 N·m. The transmission system is paired with a 6-speed dual-clutch gearbox.
