Here are the reasons why the car can't start and the gear can't be shifted: 1. No fuel: If the fuel gauge shows below the red line, the car naturally won't start. 2. Dead battery: This could be due to a drained battery from leaving the headlights on for too long or the battery's lifespan has expired. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, DVD players, etc., can also cause vehicle circuit failures. Checking for a dead battery is simple—just press the horn to find out. 3. Incorrect gear position: When starting an automatic transmission car, the gear must be in the P (Park) or N (Neutral) position. If it's in R (Reverse) or D (Drive), the car won't start. Some manual transmission cars also won't start if the clutch isn't pressed.

That winter when I went out, the car just wouldn't start, and the gear was stuck in P position. My first thought was the battery issue, especially since batteries are prone to fail in winter. Using a multimeter, I measured the voltage to be less than 10 volts—sure enough, the battery was done for. I also checked the steering wheel lock and found it was indeed locked, which can also prevent gear shifting. The brake pedal was unusually hard to press, probably due to insufficient vacuum boost. In the end, I had to jump-start the car with a friend's help and drove to the repair shop for a thorough check. A new battery solved the problem. The mechanic also mentioned that the vehicle's anti-theft system can sometimes cause trouble, but that wasn't the case this time. It's really important to keep an eye on the battery's condition, especially for older cars, to avoid being stranded halfway.

How to use the auto start-stop function in Volkswagen Sagitar?

Volkswagen Sagitar's auto start-stop function uses a mechanical button. To turn it on or off, simply press the button. Below is some information about the auto start-stop function in cars: The engine start-stop technology automatically shuts off the engine when the vehicle comes to a temporary stop during driving. When it's time to move forward again, the system automatically restarts the engine. Additional information: The working principle of the start-stop system is: 1. The driver sits in the cockpit, and when the traffic light ahead turns red, the driver presses the brake pedal and shifts to neutral; 2. The Start/Stop system automatically checks: the engine is idling and not in gear; the wheel speed sensors of the anti-lock system show zero; the electronic battery sensor indicates there is enough energy for the next start. After these three conditions are met, the engine automatically stops; 3. When the light turns green, the driver presses the clutch, and the "start stopper" can be activated immediately, quickly starting the engine. The driver shifts gears, presses the accelerator, and the vehicle starts quickly. Supported by efficient battery technology and corresponding engine management programs, the start-stop system can also work normally at lower temperatures, requiring only a brief warm-up process to activate.

What are the methods for testing the quality of engine oil?

There are several methods for testing the quality of engine oil: 1. Check the composition of the oil: Engine oils can be categorized into four types based on their composition: full synthetic, semi-synthetic, mineral synthetic, and mineral oil. Full synthetic oil is of higher quality because it has superior cleaning properties, keeps the engine cylinder cleaner during use, allows for smoother cold starts, improves fuel efficiency, has a longer replacement cycle, and provides lubrication effectiveness equivalent to 1.5 times or more that of conventional lubricants. 2. Observe the color of the oil: Imported engine oil is typically golden with a slight blue tint and is crystal clear. Genuine bulk oil is usually light blue with a bright luster and flows evenly. Any oil with uneven color or streaks of different colors during flow is likely counterfeit or deteriorated, and using such oil can severely damage the engine. 3. Smell the oil: Qualified engine oil should have no strong odor, only a slight aromatic scent. If the oil has a pungent smell, especially a strong fuel odor, it is likely recycled oil. 4. Inspect the oil: Perform a drop test by placing a drop of oil from the oil pan onto white paper. Observe the oil drop. If the center of the drop has a large, dark brown spot that is uniform without particles and the surrounding yellow area is very small, it indicates that the oil has deteriorated and should be replaced.

What to Do for the Second Maintenance?

Items for the second maintenance of a car include: 1. Change the engine oil, oil filter, and fuel filter. 2. Check if the tire pressure is normal. 3. Inspect whether the suspension arms and shock absorbers are securely fixed and functioning properly, and ensure the wheel hub bearings do not overheat after driving. 4. Check if the steering free play and toe-in meet the requirements. The steering should be light, flexible, and reliable, with no lateral wobble or deviation of the front wheels during driving. 5. Verify that the clutch free play meets the requirements. The clutch should operate smoothly, disengage completely, engage steadily and reliably, with no abnormal noises, and the hydraulic system should not leak. 6. Inspect the transmission, drive axle, or half-shaft drive device for good lubrication, secure connections, no abnormal noises or overheating, smooth gear shifting, and no oil leaks. 7. Check if the brake pedal free play and brake clearance meet the requirements. The service and parking brakes should function well, with no deviation or dragging during braking, and the inertia proportioning valve should work normally without leaks. 8. Examine the generator, starter, lights, instruments, signal lights, buttons, switches, and other auxiliary equipment to ensure they are complete and functioning normally. Lubricate all lubrication points of the vehicle. Replace the air filter, cabin air filter, and add brake fluid, power steering fluid, antifreeze, etc.

Why is there no specific time when scheduling Subject 1?

Scheduling Subject 1 does not have fixed time slots for some test centers, so after successfully scheduling Subject 1, the SMS notification or the Traffic Management 12123 App will only show which session it is, without specifying the exact time. You can estimate the exam time based on the session. Subject 1 exam session schedule: Subject 1 first session exam time is 9:00; Subject 1 second session exam time is 10:00; Subject 1 third session exam time is 13:00; Subject 1 fourth session exam time is 14:00; Subject 1 fifth session exam time is 15:00. Subject 1 is also known as Subject 1 theory test or driver theory test, which is part of the motor vehicle driver's license assessment. The total time for the Subject 1 exam is 45 minutes. The exam paper consists of 100 questions, including true/false and multiple-choice questions, with a full score of 100 and a passing score of 90. The exam 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."

What are the common specifications and models of car tires?

Common specifications and models of car tires are 205/55R16, 185/65R15, and 185/65R14. The first numbers 205 and 185 represent the tire width in millimeters. The numbers 65 and 55 indicate the aspect ratio of the tire's cross-section, which is 65% and 55% respectively, meaning the height of the cross-section is 65% or 55% of the width. The numbers 14, 15, and 16 represent the rim diameter in inches. The letter "R" in the middle stands for radial tire. Tires also have speed rating letters, indicating the maximum speed at which the tire can carry a specified load under defined conditions. Letters from A to Z represent certified speed ratings ranging from 4.8 km/h to 300 km/h. Generally, the size of car tires varies depending on the actual configuration of the vehicle. International standard tire codes use millimeters as the unit to denote the cross-section height and aspect ratio percentage. These are followed by several components: the tire type code, rim diameter, load index (also known as the allowable load mass code), and the allowable speed code. Tires are crucial components of a car, with over 10 types of markings on them. Correctly identifying these markings is essential for selecting, using, and maintaining tires, ensuring driving safety and prolonging tire life. Typically mounted on metal rims, tires support the vehicle body, cushion external impacts, ensure contact with the road, and maintain driving performance. Tires operate under complex and demanding conditions, enduring various deformations, loads, forces, and temperature extremes. Thus, they must possess high load-bearing, traction, and cushioning capabilities, along with high wear resistance, flexibility, and low rolling resistance and heat generation. Tire specifications: Specifications are data indicating the geometric parameters and physical properties of a tire. There are three methods to denote tire specifications: A. Metric (m); B. Mixed metric and imperial; C. Imperial. Imperial tire specifications are usually represented by a set of numbers, where the first number indicates the tire cross-section width, and the second number denotes the rim diameter, both in inches. Tires can be classified into approximately 8 types based on vehicle categories: PC—Passenger car tires; LT—Light truck tires; TB—Truck and bus tires; AG—Agricultural vehicle tires; OTR—Off-the-road tires; ID—Industrial vehicle tires; AC—Aircraft tires; MC—Motorcycle tires. Structurally, tires can be divided into bias-ply tires and radial tires. Modern cars predominantly use radial tires, denoted by the letter R, while bias-ply tires are denoted by D. The fundamental difference lies in the carcass: bias-ply tires have crisscrossed layers of fabric, whereas radial tires have multiple layers of polymer materials with steel belt layers on top, reducing the likelihood of punctures by foreign objects.
