How Long Can You Drive When the Oil Level is Low?

Is an exam required to upgrade from C1 to B2?

An exam is required. Conditions for upgrading from a C1 driver's license to a B2 driver's license: Age between 20 and 60 years old; Height not less than 155cm; Held a C1 driver's license for at least 1 year; No record of accumulating 12 penalty points in the current scoring cycle or the most recent scoring cycle before application; Visual acuity must meet or exceed 5.0 on the logarithmic visual acuity chart; No record of drunk driving or being primarily responsible for a traffic accident causing injuries or deaths while holding a C1 license. Specific process for applying for a B2 driver's license: Apply to the vehicle management office for adding the B2 license type; Fill out the application form, submit ID card and physical examination form, and provide the original copy of the current motor vehicle driver's license; Attend theoretical and practical exams as scheduled; Receive the new-level driver's license from the applying vehicle management office within 7 working days after passing the exams.

Can the Electronic Parking Brake A be Left On All the Time?

Electronic Parking Brake A can remain activated. In models equipped with an electronic parking brake, if the AUTOHOLD button is pressed and lit, it means the automatic mode is enabled, allowing it to stay on continuously. The parking brake will automatically engage when the engine is turned off and the vehicle is parked, and it will automatically release when starting. Below are some braking techniques: 1. Emergency Braking: Some vehicles do not have ABS, so it is not recommended to fully press the brake pedal at once. Instead, press it twice in succession to prevent wheel lock-up, which could lead to skidding or loss of steering control. 2. Wet Weather Braking: When driving on wet roads, avoid slamming the brake pedal or jerking the steering wheel. After passing through water, it is advisable to gently press the brake pedal twice to use inertia and friction to remove water from the brake discs, preventing brake failure during sudden braking. 3. Braking While Following Another Vehicle: When following another car, braking is mainly to maintain a safe distance. Therefore, press the brake pedal gently. Besides observing the braking of the car in front, also pay attention to the dynamics of the vehicle ahead of it. If you notice the car in front braking, place your foot on the brake pedal in advance to prepare for sudden braking by the leading vehicle.

Is the Water Dripping Under the Car from the Air Conditioner or a Damaged Radiator?

Whether the water dripping under the car is from the air conditioner or a damaged radiator mainly depends on whether the air conditioner is in use. If the car is using the air conditioner, a small amount of dripping water is normal, as it is the condensate from the air conditioner. If the air conditioner is not in use and water leakage is observed, a radiator leak should be considered: check if the radiator cap is properly secured. Try pumping air into the radiator to see where the water seeps out under pressure, then decide on a repair plan. Unscrew the engine oil filler cap to check for signs of emulsified oil; if found, disassemble the engine to replace the cylinder head gasket. The reason for air conditioner water is that the evaporator box in the air conditioning system cools down, causing the warm air inside the car to condense into water droplets, which then flow out through the drain pipe. Radiator leaks usually occur below the radiator, i.e., between the car's front bumper and the engine, and the dashboard will typically issue a warning. If the water is colored, it indicates a leak in the cooling system, and the vehicle should be inspected. If the car is stationary for a while and clean, transparent water is observed, this is not a malfunction, as the engine coolant is usually antifreeze (green, red, or blue).

Should Brake Fluid Be Replaced?

Yes, it should be replaced. Changing the brake fluid in a car ensures optimal braking performance. Below are the reasons for unusual noises when braking: 1. "Hissing" sound: This indicates a fault in the caliper, brake pad, or brake shoe. 2. Continuous noise: This is caused by poor caliper retraction, leading to prolonged friction between the disc and pad. 3. Foreign objects: There may be debris between the brake pad and brake disc. 4. Faulty guide pin: The brake guide pin is malfunctioning. Below are the reasons for steering wheel vibration during braking: 1. Wear: Uneven wear on the brake disc can cause steering wheel vibration when braking at high speeds. 2. Braking imbalance: When driving at a certain speed, uneven braking torque can cause the left and right wheels on the same axle to desynchronize, resulting in brake looseness. 3. Uneven rolling speed: If the braking torque imbalance becomes severe, it can cause the left and right wheels to roll at different speeds, leading to side-to-side wheel oscillation, which is then transmitted to the steering wheel.

What are the consequences of not repairing a slipping clutch?

Consequences of not repairing a slipping clutch: A slipping clutch in a car can easily lead to insufficient driving power, posing safety hazards; the car is highly prone to oil leakage when climbing slopes, potentially causing accidents; prolonged clutch slipping can also severely damage car components, such as the clutch and flywheel. Causes of clutch slipping: Excessive wear of the driven disc friction plate or exposed rivets; the clutch pressure plate spring is too soft or broken; the clutch pedal free travel is too small; oil contamination or aging hardening on the driven disc friction plate; loose bolts connecting the clutch to the flywheel; blocked return oil hole in the clutch master cylinder. Clutch troubleshooting methods: Check the pedal free travel. If the free travel is normal, remove the clutch bottom cover and check whether the bolts connecting the clutch cover to the flywheel are loose. If loose, tighten them; if they do not meet the standard value, adjust them. Check if there is oil splashed from the edges of the clutch friction plate. If oil is present, remove and clean with gasoline or alkaline water, then dry; if severe wear, exposed rivets, aging hardening, burning, or oil saturation are found on the friction plate, replace it with a new one. Check the return oil hole of the clutch master cylinder, and unclog it if blocked.

What is the Function of an Electronically Controlled Automatic Transmission?

The function of an electronically controlled automatic transmission is to select the optimal gear ratio for different loads and vehicle speeds, ensuring the engine operates at a corresponding stable speed. All gear shifts are performed automatically by the transmission, with the driver only needing to use the accelerator pedal to indicate their intent for speed changes and the gear selector to choose the desired operating mode. The electronically controlled automatic transmission is developed by adding an electronic control system to the traditional hydraulic automatic transmission. Common types of automotive automatic transmissions include: hydraulic automatic transmission (AT), continuously variable transmission (CVT), automated manual transmission (AMT), and dual-clutch automatic transmission.
