Car has no internet connection due to poor network signal in the location. Or there might be a network connection error, check if the network exists. Below are the specific details about in-car network: 1. Top-up method: When the in-car network data is used up, you can top up at a local service provider. If there is a data card provided by the car manufacturer, you can contact the 4S store for top-up. 2. Free usage explanation: Most in-car networks are not permanently free. Currently, most in-car networks only provide the car owner with 2G of free data per month. When the data is used up, additional purchase is required. Some new energy vehicle brands also offer lifetime free trial of the network.

Having driven for over a decade, the most common causes I've encountered for car connectivity issues are signal problems or expired services. When driving into underground parking or remote mountainous areas, weak signals naturally lead to disconnections—I usually try moving to an open area. It could also be due to depleted or expired data plans from the carrier, as in-car SIM cards, like mobile ones, require regular top-ups. Hardware-wise, loose antennas or faulty modules can disrupt connectivity, requiring a mechanic to diagnose with specialized tools. Additionally, system bugs often emerge after software updates, which can usually be fixed by rebooting the infotainment system or reconnecting the network in settings. Remember to periodically check the network status in your vehicle settings—don’t overlook these small details. During routine maintenance, remind technicians to inspect antenna connections. Most cases can be resolved with simple troubleshooting, so there’s no need for excessive worry.

What is the full name of Subject 4?

Subject 4, officially known as Subject 4 Theoretical Test or Driver's Theoretical Test, is part of the motor vehicle driver's license assessment. Below are the relevant details: Test Timing for Subject 4: Theoretically, you can schedule the Subject 4 test immediately after passing Subject 3, with no specific waiting period required. However, due to varying local policies, the interval between Subject 3 and Subject 4 may differ. In some regions, you can take Subject 4 right after passing Subject 3, meaning you could complete both tests on the same day. Other areas may require a one-week waiting period before scheduling Subject 4. Test Content for Subject 4: The exam covers safe and civilized driving practices, knowledge of safe driving under adverse weather and complex road conditions, emergency handling procedures such as tire blowouts, and post-accident response measures. Also referred to as the Theoretical Test or Driver's Theory Exam, Subject 4 evaluates 'driving ethics.'

Is there a safety officer in the car during Subject 2 test?

There is no safety officer in the car during Subject 2 test, only staff members in the testing area. Your score is evaluated by the onboard electronic equipment, and you need to sign the document when you pass the test. Here is a detailed introduction about it: Subject 2, also known as the small road test, is part of the motor vehicle driver's license examination and refers to the field driving skills test. Test items include: stake test, slope fixed-point parking and starting, parallel parking, passing single-plank bridge, curve driving, right-angle turn, passing width-limited gate, passing continuous obstacles, driving on bumpy roads, narrow road U-turn, as well as simulated highway driving, continuous sharp turns on mountain roads, tunnels, rain (fog) weather, slippery roads, and emergency situation handling.

How to Make Car Windshield Washer Fluid?

Here are the methods for making homemade windshield washer fluid: 1. Spring Windshield Washer Fluid: Prepare a 2.5-liter plastic bottle, 2 liters of purified water, 250ML of 95% medical alcohol, and 1-2 caps of detergent. Mix them thoroughly and it's ready for use. The detergent is mainly for removing sand and dust, while the alcohol accelerates water evaporation, ensuring quick cleaning of the windshield. 2. Summer/Autumn Windshield Washer Fluid: Use a 2.5-liter plastic bottle, 2 liters of purified water, 500ML of 95% medical alcohol, and 1 cap of detergent. The alcohol is very effective in removing insect residue. If you're in the city, you can top up the reservoir with purified water, but it's not recommended to dilute the mixture on highways as it may reduce effectiveness. 3. Winter Windshield Washer Fluid: A mixture of 20% 95-proof alcohol and 80% water has a freezing point around -10°C, suitable for early winter. A mixture of 20-30% alcohol and 60% water has a freezing point of -15°C. A mixture of 40-50% alcohol and 50-60% water can reach a freezing point of -25°C without freezing, meeting most winter needs.

Can You Stall the Engine in Subject Two?

You only need to complete tasks such as reversing into a garage, parallel parking, stopping on a slope, turning at a right angle, and driving on a curve, then return to the starting point after the assessment. There is no need to stall the engine. Here is an introduction to Subject Two: 1. Introduction One: Subject Two, 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 skills test. 2. Introduction Two: The test items include five mandatory tasks: reversing into a garage, parallel parking, stopping on a slope, turning at a right angle, and driving on a curve. Here are the precautions for Subject Two: 1. Introduction One: Do not wear items that obscure your face when taking photos, such as scarves, masks, hats, etc. 2. Introduction Two: When getting into the car, actively show your ID card, adjust the seat, turn on the left turn signal, fasten the seat belt, release the handbrake, and enter the test area only after hearing that the identity verification is successful. 3. Introduction Three: If the vehicle ahead is reversing into a garage, wait outside the arrow until the vehicle ahead moves to parallel parking before starting your test. 4. Introduction Four: For parallel parking, align with the reference point ahead, avoid pressing the solid lines on both sides, and keep the right wheel 20-50 cm away from the garage line. 5. Introduction Five: Wait for the vehicle ahead to exit before entering the curve driving test. If there is a vehicle ahead, wait outside the arrow. 6. Introduction Six: When starting on a slope, do not wait for the computer voice announcement because you must complete the starting action within 30 seconds. Do as you usually practice to ensure a smooth start without stalling or rolling back. 7. Introduction Seven: For turning at a right angle, control the speed carefully—do not go too fast. Align with the reference point, straighten the direction, identify the point ahead, and quickly turn the steering wheel fully to the left.

Does coasting with the clutch fully depressed damage the clutch?

This is a standard operation. For manual transmission vehicles, braking involves fully depressing the clutch while simultaneously applying the brakes. During this process, there is inevitably a period of coasting, which does not inherently damage the vehicle. However, prolonged coasting in this manner carries certain safety risks. If braking is not intended for stopping, there's no need to depress the clutch—simply apply light brake pressure. Additional information: Reason: When the clutch is fully depressed, the engine and transmission are disconnected, causing the vehicle to lose power. This state imposes no wear on the engine or transmission. Braking in this condition does not harm the vehicle, as the engine and transmission are already disengaged. However, relying solely on the brakes for deceleration without engine braking increases the burden on the braking system over time, potentially compromising driving safety. Precautions: As the vehicle speed decreases, downshift sequentially through gears 6/5/4/3/2/1. Coasting in gear can achieve an average coasting distance of over 80% without fuel injection. This is because the vehicle's inertial force during coasting drives the transmission system and engine in reverse through the wheels. With no operational load, the fuel injection system can cease fuel delivery.

What is the equivalent of 30 psi in atmospheric pressure?

30 psi is equivalent to 2 standard atmospheric pressures. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. Sharp objects like nails or glass can easily penetrate the tire, leading to internal cracks or blowouts. Methods for insufficient tire pressure: If no damage is visible, inflate to normal pressure and reset the tire pressure system; If a puncture is found, promptly drive to a tire shop for repair and reinflation; If the tire pressure warning reappears after inflation without any punctures, it may be due to a leaking wheel rim deformation. Check and replace the rim if necessary.
