What does it mean when the AT light in a car is on?

1 Answers

When the AT light in a car is on, it indicates a transmission fault. Symptoms of transmission fault light activation: Issues such as jerking, abnormal noises, slipping, or impact may occur, which require timely repair. If the AT light is on, you can try turning off the engine and restarting to see if it returns to normal. If it does not return to normal or if there is shifting impact, it is usually a real fault in the transmission system. Car Transmission: The transmission is a mechanism used to change the speed and torque from the engine, fixed or stepped to alter the transmission ratio between the output shaft and the input shaft, also known as the gearbox. The transmission consists of a transmission mechanism and a control mechanism, and some cars also have a power take-off mechanism.

How to Use Corolla Adaptive Cruise Control?

Toyota Corolla adaptive cruise control usage is as follows: 1. Press the cruise control button on the right side of the steering wheel for no more than 1.5 seconds. 2. Press the distance-keeping button, then accelerate to your desired maximum speed. 3. Press the SET button, and the vehicle will automatically cruise at the speed and distance set when the button was pressed. Relevant information is as follows: 1. The adaptive cruise control system uses low-power radar or infrared beams to detect objects up to about 200m ahead, obtaining the exact position of the vehicle in front. If it detects that the front vehicle is slowing down or a new target is identified, the system sends execution signals to the engine or braking system to reduce speed, maintaining a safe distance between your vehicle and the one ahead. 2. The most basic function of adaptive cruise control is to maintain the vehicle's longitudinal movement. In case of a collision risk, the vehicle will alert the driver and actively intervene with braking.

What is the correct method for adding refrigerant to a car?

Automotive air conditioning refrigerant, commonly referred to as car refrigerant, is mainly divided into two types: environmentally friendly 134a and non-environmentally friendly R12. The correct method for adding refrigerant to a car is as follows: 1. After the system is vacuumed, close the high and low pressure manual valves on the manifold pressure gauge. 2. Connect one end of the middle hose to the joint of the refrigerant tank injection valve, open the refrigerant tank valve, then loosen the nut at one end of the manifold pressure gauge hose to allow gas to escape for a few minutes, and then tighten the nut. 3. Fully open the high-pressure side manual valve and invert the refrigerant tank. 4. Inject the specified amount of liquid refrigerant from the high-pressure side, close the refrigerant tank injection valve and the high-pressure manual valve on the manifold pressure gauge, then remove the gauge. When adding refrigerant to the system from the high-pressure side, ensure the engine is not running, and do not open the low-pressure manual valve on the manifold pressure gauge to prevent hydraulic shock.

What are the emergency solutions for a car with a dead battery?

There are several emergency solutions for a car with a dead battery: 1. Jump-starting. First, connect the positive terminals of both cars with a red cable, and the negative terminals with a black cable. In this case, you can use a metal part in the engine compartment as the negative terminal, commonly known as grounding. After connecting, start the ignition. 2. Push-starting. First, turn the key to the ignition position, press the clutch, release the handbrake, and put the gear in 1st or 2nd. Keep the clutch pressed and start pushing the car. When the speed reaches 5 km/h, slowly release the clutch and press the accelerator to start the car. 3. Using a portable car emergency charger. The principle of a car emergency charger is similar to that of a phone power bank. When the battery is dead, you can charge the car to start it.
