What does 'lock' mean in a car?

lock refers to the ignition switch. The switch of the car's ignition system (usually requiring a key) can freely open or close the main circuit of the ignition coil. Here is additional information: 1. The activation method is to insert the key into the ignition switch, pause briefly at each gear for about 1-2 seconds, during which you can hear the sound of electrical equipment powering on, and then proceed to the next gear. Some cars can directly enter the ON position, wait for all electrical systems to fully start up (approximately 6-7 seconds), and then turn the key to the START state to ignite directly. 2. The one-button start button or knob can only be activated when it detects the presence of the smart key, with a typical sensing range of about 50 centimeters.

How to Remove a 3M Adhesive Spoiler?

3M adhesive spoiler removal method: Use a hair dryer to slowly heat it, allowing the adhesive to soften, then wipe it off with an eraser; alternatively, you can use an adhesive remover, which can easily remove various types of adhesive residues. The adhesive remover can peel off stickers on car windows, body surfaces, paint surfaces, glass, marble surfaces, etc. A car spoiler refers to the ducktail-shaped protrusion installed at the rear end of the car trunk lid, which is part of the car's aerodynamic kit. Its main function is to reduce the lift at the rear of the vehicle. If the lift at the rear is greater than that at the front, it can easily lead to excessive steering, reduced rear wheel grip, and poor high-speed stability.

Is the Electronic Parking Brake Effective After the Engine is Turned Off?

Electronic parking brake remains effective after the engine is turned off. The electronic parking brake is a technology that achieves parking braking through electronic control. Its working principle is the same as that of a mechanical handbrake, both relying on the friction generated between the brake disc and the brake pads to control parking braking. The only difference is that the control method has changed from the previous mechanical handbrake lever to an electronic button. The electronic parking brake, also known as the electronic parking brake system, integrates the temporary braking function during driving with the long-term braking function after parking, and achieves parking braking through electronic control. Its advantages include saving the space occupied by the mechanical handbrake and creating a larger center console space.

What Does Air Suspension Modification Mean?

Air suspension modification refers to a type of shock absorber that controls the vehicle's height through air pressure. The working principle of air suspension involves adjusting the vehicle's height by regulating air pressure. It consists of elastic rubber airbag shock absorbers, a pneumatic control system, a trunk-mounted air tank, and an electronic control system. Air suspension is not only found in modified vehicles but is also installed in many factory models, such as the Jeep Grand Cherokee, Land Rover Discovery, and even many supercars come with factory air suspension. Modified air suspension systems typically include a connected remote control inside the vehicle, allowing the owner to preset several height settings for quick switching between different levels. This enables the car to "slam" to the ground when parked and rise to a normal driving height when in motion.

What to Do When the Auto Start-Stop Function Doesn't Work?

Solutions for when the auto start-stop function doesn't work: Turn off the engine, disconnect the positive terminal of the battery, reconnect it after 5 minutes, insert the key and turn it to ON (dashboard indicators will light up), wait for 30 seconds, then remove the key. The auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) and restarts it when it's time to move again. Situations where the auto start-stop may not function properly include: 1. The engine coolant temperature hasn't risen after a cold start; 2. The outside temperature is below 5 degrees or the inside temperature is below 20 degrees with the heater on; 3. Insufficient battery charge; 4. The steering wheel angle exceeds 30 degrees; 5. Front seat belts are not fastened; 6. Parking on a slope.

What Causes the Smell of Gasoline During Cold Start?

Reasons for strong gasoline smell during cold start: If it's a carburetor vehicle, it's a normal phenomenon due to incomplete combustion during startup. For fuel-injected vehicles, it can be preliminarily judged as a damaged activated carbon canister. Here is some extended information: 1. Low Temperature: When the external temperature is very low, and both the water temperature and exhaust pipe temperature are low, combined with the cold engine start in winter, the air-fuel mixture becomes richer. As a result, some of the mixture cannot burn completely and is directly expelled through the exhaust pipe, leading to a noticeable gasoline smell. This is normal. 2. Carbon Canister Malfunction: Another reason could be issues with the carbon canister or the carbon canister solenoid valve, causing an overly rich air-fuel mixture during startup. 3. Excessive Engine Carbon Buildup: If the local temperature is low and there is excessive carbon buildup inside the engine, it can lead to poor atomization of the air-fuel mixture, resulting in this phenomenon. 4. Solenoid Valve Closed: If the solenoid valve remains closed, gasoline vapor in the carbon canister will accumulate and eventually fill the entire canister. The excess vapor will then escape into the atmosphere, causing a gasoline smell. 5. Fuel Injector Leakage: If the fuel injector is leaking, it can cause an overly rich air-fuel mixture. The unburned mixture will be expelled through the exhaust pipe, leading to a strong gasoline smell.
