Restart the navigation system or restore factory settings. The restart button is a very small built-in button located on the back or side of the device, and all GPS navigation devices have this button. Below are the reasons for navigation screen malfunction: 1. Static electricity: Although the surface glass of the navigation touchscreen is treated to resist static electricity, it is still susceptible to static, especially conductive media like oil and sweat from the driver's hands. 2. High temperature: The navigation touchscreen is sensitive to high temperatures. If the car interior reaches around 40°C, it can cause the capacitive screen to drift, so try to avoid parking the car under direct sunlight. 3. Magnetic fields: Magnetic fields inside the car, even a small magnet, can temporarily disable the touchscreen.

Where is the car fuel tank cap switch located?

Generally, the fuel tank cap switch is located on the center console or the left front door panel, and some are on the left side of the driver's seat. The switch is usually marked with a fuel refill icon. To understand how to open the car fuel tank cap, we need to know its structure. Modern cars typically allow remote control of the trunk and fuel tank cap from inside the cabin, providing great convenience to the owner. However, when these features malfunction, they can leave the owner helpless and cause significant inconvenience. Most cars have the fuel filler on the left rear or right rear side, so locating the fuel filler is simply a matter of identifying which side of the vehicle it is on. The easiest method is to check the fuel filler side before getting into the car. If you forget to observe beforehand, there's no need to stop and check—most car dashboards have an indicator. Next to the fuel gauge, there is usually a fuel pump symbol with a small triangular arrow pointing toward the side where the fuel filler is located. Most car dashboards include this indicator, even electronic fuel gauges typically retain this feature. There are generally three ways to open a car fuel tank cap: push-to-open, switch-button, and mechanical key.

How many kilometers is 120 mph?

120 mph equals 193.08 kilometers per hour. Unit conversion: Miles and kilometers are completely different units. 'Mile' refers to the British imperial unit where 1 mile = 1609 meters, equivalent to 1.609 kilometers. Therefore, 120 mph converts to 193.08 km/h (120 mph = 120 × 1.609 = 193.08 km/h). About speed units: 'Yard' is a British imperial length unit. Converted to the international standard: 1 yard = 0.9144 meters. 'Mile' is also a British imperial unit, with 1 mile = 1609 meters in international units.

Does no response during the second ignition count as a second ignition?

No response during the second ignition still counts as a second ignition. Reasons for no response during the second ignition: No fuel. If the fuel gauge shows below the red line, the engine naturally won't start; dead battery. This could be due to prolonged use of headlights without turning them off, resulting in a drained battery, or the battery's lifespan has expired. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights or high-power audio systems can also cause vehicle circuit failures; incorrect gear position. For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) to start. If left in R (Reverse) or D (Drive), the engine won't start. Some manual transmission vehicles also won't start if the clutch isn't depressed. Hazards of second ignition: Frequent second ignition can damage the starter motor, starter engagement gear, and the flywheel gear ring on the engine. Normally, turning the ignition key first activates the starter motor. The starter's drive gear engages with the teeth on the flywheel, causing the flywheel to rotate. Finally, with the coordination of the valve timing, ignition, and other mechanisms, the engine starts running. Once the engine starts, the starter motor stops working. Sometimes, because the engine sound is relatively quiet or the engine runs smoothly after starting, many car owners may mistakenly think the engine hasn't started and proceed with a second ignition, which can more or less cause certain damage to vehicle components.

What does engine start-stop mean?

Engine start-stop refers to a system that can automatically shut off the engine when the vehicle comes to a temporary stop during driving, such as waiting at a red light. When the car needs to move forward again, the system can automatically restart the engine. Features of start-stop technology: In ordinary start-stop technology, the engine automatically turns off when the car encounters a red light or traffic jam. When the driver releases the brake pedal or steps on the clutch (or accelerator pedal), the engine promptly restarts on its own. More complex start-stop systems also include brake energy recovery functionality, which can convert part of the energy from the braking process into electricity to charge the battery. Functions of engine start-stop: It is used when the car is moving at low speeds or repeatedly stopping, helping to automatically shut off the engine to avoid unnecessary fuel consumption. It also reduces the car's idle time, which in turn decreases engine carbon buildup, benefiting both environmental protection and the engine's lifespan.

How Many Points Are Deducted for Each Violation in Subject 2?

Different items in Subject 2 have different point deductions. The specific regulations are as follows: Not wearing a seatbelt deducts 100 points; starting the engine without the gear in neutral deducts 100 points; not using the turn signal (including starting, changing lanes, overtaking, turning, or parking by the roadside), using the turn signal for less than 3 seconds, forgetting to turn off the turn signal, or incorrect use of the turn signal deducts 10 points; stalling the engine once deducts 10 points; driving over the edge line deducts 100 points; stopping for more than 2 seconds deducts 5 points; not following the prescribed route or sequence deducts 100 points; failing to reverse into the parking space deducts 100 points; the vehicle body crossing the line deducts 100 points. In Subject 2, special attention should be paid to reversing into the garage and parallel parking, as driving over the edge line will directly deduct 100 points. Introduction to Subject 2: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment and is the abbreviation for the field driving skill test. The C1 test items include five compulsory tests: reversing into the garage, parallel parking, stopping and starting on a slope, turning at a right angle, and curve driving (commonly known as the S-curve) (some areas also have a sixth item, high-speed card collection). The C2 test items include four compulsory tests: reversing into the garage, parallel parking, turning at a right angle, and curve driving (commonly known as the S-curve).
