The reasons for the car's one-button start not responding are: 1. The vehicle key is out of battery or the battery is about to run out; 2. The radio waves of the car key are being interfered with; 3. The one-button start function cannot be used when the steering wheel is locked; 4. Car malfunctions causing the one-button start to not respond, such as a dead battery or insufficient voltage, or short circuits in electronic components. The principle of one-button start is based on radio frequency identification technology, which automatically locks and unlocks the doors through the chip in the smart card carried by the owner. When the owner approaches the vehicle, the car automatically recognizes the owner's identity, the door locks will automatically open, and the anti-theft system will be deactivated, eliminating the need to search for a key.

As an experienced driver, I've also encountered situations where the one-touch start didn't respond, and I had to press the brake pedal hard. The one-touch start has a safety design that requires the system to detect the brake signal before unlocking the start permission. The key is to check if the floor mat is blocking the brake pedal. Last time, the plush floor mat in my car shifted, and the brake pedal only went down two-thirds of the way, causing the car to refuse to start. Also, if the smart key's battery is too low, it won't work—check if the key's red light is flashing and try placing it in the cup holder's induction area for emergency start. Older cars often have issues with the steering wheel being locked and unable to turn—remember to wiggle the steering wheel left and right while pressing the start button. If all else fails, use the back of the key to press the start button forcefully, but this method can damage electronic devices, and the dealership technicians advise against using it unless absolutely necessary.

What to Do When Transmission Fluid Temperature Is Too High?

Transmission fluid overheating is generally caused by coolant issues, so regularly replacing high-quality coolant can prevent transmission fluid overheating. Below is extended information: 1. Fluid temperature below 135°C: Generally, transmission fluid temperature should not exceed 120°, with 80° or 90° being optimal. Prolonged temperatures above this range will accelerate the degradation of transmission fluid components and usability. Under normal driving conditions, transmission fluid temperature is typically below 135°C. 2. Fluid temperature reaches 135°C: Excessive vehicle use, such as overloading towing, driving in 4WD mode set for snow or off-road conditions, or operating with excessive torque converter slippage, may cause transmission fluid temperature to reach 135°C. When the transmission fluid temperature hits 135°C, an installed transmission fluid overheating warning system will simultaneously display "Oo-135c" (Note: "Oo" stands for Oi-Overheating) and emit a chime as an alert. The purpose of the warning is to actively prompt the user to stop the vehicle, shift to neutral, engage the parking brake, and keep the engine idling, allowing the fluid circulation to enter cooling mode for rapid temperature reduction until the alarm signal disappears, thereby avoiding potential safety hazards caused by continuously rising fluid temperature.

How to Activate the Lock Sound on Volkswagen Vehicles?

Activation method for the lock sound on Volkswagen vehicles: The lock sound is not enabled by default in the factory settings, meaning the horn does not sound when the doors are locked.

Can You Still Drive When the Engine Shows Insufficient Power?

You can continue driving when the engine shows insufficient power, but it is recommended to identify the cause of the issue as soon as possible. Below are the reasons that may lead to insufficient engine power: Excessive carbon buildup in the engine: Carbon deposits can directly affect the engine, reducing its performance and causing insufficient power. Therefore, regular cleaning of engine carbon deposits, using high-quality fuel, and minimizing carbon buildup are essential. Excessively high or low temperatures: High water temperature is usually caused by prolonged overloading, severe scaling in the cooling system, excessive fuel supply, or delayed fuel injection timing. Avoid prolonged overloading of the vehicle, clean the cooling system of scale, reduce fuel supply, and adjust fuel injection timing. Clogged air filter: A clogged air filter increases intake resistance and reduces the amount of air entering the cylinders, leading to incomplete diesel combustion and insufficient engine power.

What Engine Displacement of Motorcycles is Exempt from Purchase Tax?

When purchasing a used car, if the original owner has already paid the purchase tax, the new owner does not need to pay it. If the tax was not previously paid, the new owner must make up the purchase tax portion.
