ON means on, and the OFF button means off. ON and OFF are two common buttons found in cars, typically seen on the light control lever, used to turn the car lights on or off. Besides ON and OFF buttons, cars also include SEL, OK, AC, VOL+, VOL-, MUTE, MODE, and SET. The AC button is the compressor button for the car's air conditioning, functioning as the cooling switch, used when operating the air conditioning in summer. VOL+ and VOL- refer to the volume control buttons in the car, which adjust the volume of the car audio. MUTE is the mute button in the car; pressing this button while playing music will instantly mute the sound.

I remember when I first started driving, I didn't understand this button either. Later, I learned that the ON button is the key to activating the air conditioning. Pressing it powers up the entire AC system, allowing you to adjust the temperature and fan speed. Some car designs automatically activate the vents, but manually pressing the ON button is more intuitive. Actually, experienced drivers know that turning on the ON button before adjusting the temperature in winter saves the most fuel—much smarter than directly pressing AUTO. Plus, if you notice any issues with the fan speed, promptly power off and get it checked to prevent minor problems from turning into major faults.

How to adjust the clutch of a Toyota Corolla?

Toyota Corolla clutch adjustment method: There is a small clutch lever near the transmission under the car. At the connection point between the lever and the clutch cable, there is a screw that can be used to adjust the clutch height. After adjustment, start the car to test the tightness of the clutch. When pressing the clutch, try to use the front part of your foot for better force application and more stable, thorough pressing. Remember not to use the middle or heel of your foot. Taking the Corolla 2021 1.2T S-CVT Pioneer PLUS version as an example: It is a compact car launched by FAW Toyota, with a length, width, and height of 4635mm, 1780mm, and 1455mm respectively, and a wheelbase of 2700mm.

Do Scooter Motorcycles Require a Driver's License?

Scooter motorcycles, like other motorcycles, require a driver's license. For engines with a displacement of 50CC or above (including 50CC), an E or D license is mandatory. For engines with a displacement below 50CC (excluding 50CC, including so-called 48CC), an F license is required. Driver's License Application Locations: Applicants residing in their household registration area should apply there. Those residing temporarily can apply in their temporary residence area. Active military personnel (including armed police) should apply at their station. Foreign nationals should apply at their place of residence. For adding a permitted vehicle type, applications should be made at the issuing location of the current motor vehicle driver's license. Driving Age Requirements: Applicants for small cars, small automatic transmission cars, small automatic transmission passenger cars for the disabled, or light motorcycles must be between 18 and 70 years old. Applicants for low-speed trucks, three-wheeled cars, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, or wheeled self-propelled machinery must be between 18 and 60 years old.

Methods for Repairing Small Dents on Cars

Here are the methods for repairing small dents on cars: 1. When the car bumper is dented, prepare a pot of boiling water and pour it over the dented area. The dent will slowly pop back out, achieving automatic repair. 2. Depending on the location of the small dent, choose an appropriate round-headed pry bar. Place the pry bar inside the car body and use the round-headed part to gently lift the dent with suitable force. Observe the reference surface of the raised area from the car body's surface, and stop applying force when the raised part just exceeds the metal sheet reference surface. For areas where the pry bar cannot reach, such as double-layered or multi-layered sections of the car body, a dent puller can be used for repair. 3. Visit a 4S shop for repair. For minor car dents, metal sheet and paintwork are used. For severe car dents, replace the damaged part and then repaint. 4. When repairing dents, pay attention to the position, size, and thickness of the metal sheet to select the appropriate current. If the current is too low, the electrode tip will not adhere to the metal sheet. If the current is too high, it may cause penetration or deep welding marks.

What does it mean when the ABS light comes on in a BMW?

When the ABS light is displayed on a vehicle, it indicates a malfunction in the Anti-lock Braking System. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, preventing the driver from slowing down or adjusting the vehicle's trajectory, posing significant safety risks. There are several conditions under which the ABS light may illuminate, each with different causes and solutions, as detailed below: Condition 1: ABS warning light stays on (most common). Cause 1: The ABS speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting its ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle's speed or the wheel's slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the contaminants from the speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal due to loose connections in the system wiring or poor contact in the ABS relay, leading to system failure. Solution: Inspect the wiring connections and reconnect any loose parts. Condition 2: ABS warning light intermittently illuminates but turns off when accelerating. Cause: When multiple vehicle electrical devices are in use, the battery voltage may drop below 10.5V. As the engine speed increases and voltage rises, the ABS light turns off. This can also occur if the ABS system's power supply voltage is too low due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity, inspect the charging system, and examine the power supply (e.g., voltage relay or poor power contact). Condition 3: ABS warning light stays on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body, loose wiring connections in the ABS hydraulic valve body, or ABS computer malfunction. Solution: Loosen and then retighten the grounding screw on the hydraulic valve body, cleaning the contact surface if necessary. Check for enlarged gaps in the connectors and replace the ABS or ABS/ASR computer if needed. Condition 4: ABS warning light illuminates during high-speed driving. Cause: The ABS computer detects a significant discrepancy between the rear and front wheel speed signals during high-speed driving, or incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. Condition 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch or poor internal contact in the brake light. Solution: With the engine running, press the brake pedal and use a finger to push the brake switch linkage all the way down, then release the brake pedal to complete the self-setting position. Replace the brake light switch if necessary.

How to Handle Aged New Energy Vehicle Batteries?

New energy vehicle batteries should undergo downgrading or recycling after aging. Downgrading: Refers to when the battery system detects abnormalities in voltage, current, or temperature approaching safety limits, it proactively notifies the vehicle's VCU to request power or torque limitation, thereby reducing energy output. Recycling: Battery recycling involves collecting used batteries to prevent them from entering the ecosystem and causing environmental harm. Waste batteries contain large amounts of heavy metals and electrolyte solutions such as waste acids and alkalis.
