Why does the Cadillac screen stay on after turning off the engine?

How many questions are there in the Motorcycle Subject 1 exam?

The Subject 1 exam paper consists of 100 questions, including true/false questions and single-choice questions, with a full score of 100 points 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". The exam content includes the most basic knowledge such as driving theory foundation, road safety laws and regulations, traffic signals, traffic rules, as well as local regulations. The theoretical driving test schedule is arranged by the local vehicle management offices. Exam process: Follow the instructions of the staff and collect your driving training file in order at the waiting area; Carry and present your ID card for inspection by the supervising officer; Mobile phones must be turned off when entering the exam area; No loud noise is allowed in the exam area; Regulation textbooks are not allowed to be brought into the exam area (or placed in bags); After the exam, keep your ID card safe and submit the file to the "Submission Window" at the front of the exam room; Candidates who pass the exam will sign under the guidance of the staff at the exam exit and then leave the exam room; Candidates who fail the exam can leave the exam room and wait for the driving school staff to notify them of the retake time.

What is the normal tire pressure for a Jetta?

The normal tire pressure range for a Jetta is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard requirements. The tire pressure monitoring system in the Volkswagen New Jetta can be viewed on the central control screen. The vehicle is equipped with a tire pressure monitoring system that provides automatic alarm prompts, requiring no manual operation. Generally, a tire pressure exceeding 2.8 bar is considered too high, while a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, lowering driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; weakens the function of cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim, damaging the tire bead and causing abnormal wear; multiplies friction with the ground, rapidly raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes at the bottom, and an exclamation mark inside), it is generally due to one of the following three reasons: Abnormal tire pressure: Usually triggers an alarm when pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, the tire pressure monitoring system was not reset in time, causing it to retain the previous data and trigger the indicator light. Simply reset the tire pressure monitoring to resolve this. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the tire valve, monitors tire pressure. If the sensor is damaged during driving (e.g., by hitting a curb), it can also cause the tire pressure warning light to come on. For sensor damage, the only solution is to replace it with a new part.

Is it necessary to install a bug screen on a car?

Whether it is necessary to install a bug screen on a car depends on individual circumstances. If you frequently drive on highways or in areas with many insects, installing one can be beneficial. The bug screen is installed at the front of the car to prevent insect remains from accumulating on the surface of the condenser and radiator. However, it is not recommended for most car owners to install a bug screen because it is a very fine mesh that can obstruct airflow to the radiator, reducing cooling efficiency. That said, bug screens can be useful in rural areas with many insects or during seasons with flying willow catkins, as they provide some protection.

Does Engine Start-Stop Technology Save Fuel?

Engine automatic start-stop systems save fuel, and here are the reasons: 1. Definition: The English name for engine automatic start-stop is STOP&START, abbreviated as STT. The STT intelligent fuel-saving system is a system that controls engine start and stop. 2. Principle: Automatic start-stop is achieved by installing an enhanced motor with idle start-stop functionality in a traditional engine, allowing the engine to completely shut off when the vehicle meets idle stop conditions. When the vehicle needs to start moving again, the idle start-stop motor system quickly responds to the driver's start command, rapidly restarting the engine with instantaneous engagement, thereby significantly reducing fuel consumption and exhaust emissions.

Can ETC be installed without sticking it to the windshield?

ETC does not have to be stuck to the windshield. Installing ETC on the upper part of the windshield is to minimize obstruction of the driver's view and to ensure better recognition by highway toll station equipment. As long as the highway toll station's sensing device can detect the ETC device, it can be installed on the car's dashboard or held up by hand when passing through the toll station. This will not affect the transmission of electromagnetic waves in free space. Electromagnetic waves will still refract and reflect when passing through different media, eventually reaching the signal receiver. ETC is an electronic toll collection system, and vehicles that frequently use highways usually install this device to save time when passing through toll stations.

What Causes an Automatic Transmission Car to Suddenly Stall While Driving?

Reasons for stalling: 1. Generator failure: All electrical equipment in an automatic transmission car is powered by the battery, which in turn gets its electricity from the generator. If the generator fails, the ignition system loses power, causing the car to stall. 2. Ignition system failure: The most vulnerable parts in the ignition system are the spark plugs, followed by the ignition coils and cylinder wires. If spark plugs or ignition coils in two or more cylinders fail, the car will stall. 3. Fuel system failure: Low fuel pressure can cause the car to stall. Fuel system issues may include clogged fuel lines, fuel pump failure, or pressure pump failure. Common clog-prone areas include the fuel pump filter screen.
