TRC off means the Traction Control System of the vehicle is turned off. Turning off TRC has no impact on the vehicle itself and does not affect normal driving, but it may cause wheel slippage when starting on slippery roads. The Traction Control System, abbreviated as TCS, is also known as ASR or TRC, and is referred to as the Anti-Slip Regulation system. Its main function is to maintain the stability of the vehicle while driving. Different brands may have different names for the Traction Control System, but the principles and functions remain the same. The Traction Control System helps the vehicle start or accelerate smoothly on poor road conditions (such as wet or muddy surfaces), ensuring smooth acceleration.

TRC off refers to the state where the Traction Control System is deactivated. TRC is a safety feature in vehicles that normally monitors wheel slip when enabled, automatically adjusting engine power or braking to help maintain traction. When turned off, the system stops functioning, making the car more prone to skidding or losing control during sudden acceleration or on slippery roads. Some drivers may deactivate TRC in specific situations, such as when off-roading to gain extra power if wheels are stuck, or on racetracks to pursue a purer driving experience. However, it's crucial not to turn it off during daily driving, especially in rain or snow—safety comes first. Personally, after years of driving, I’ve tried turning off TRC a few times to escape muddy terrain successfully, but I feel much safer keeping it on in city streets. Remember, the control button is usually near the dashboard—just press it to toggle the system. Always reactivate TRC immediately after special driving conditions to avoid risks from forgetting.

How many times can I earn points online for my driver's license?

There is no limit to the number of times you can participate in the 'Learn and Reduce Points' program. However, once a motor vehicle driver has reduced a total of 6 points within one scoring cycle, they will no longer be able to continue participating in the program. Below are the specific details: 1. Learn and Reduce Points: This program is designed for licensed drivers who have received demerit points due to traffic violations. By participating in online traffic safety education and passing the exam, they can have their demerit points reduced. 2. Specific Procedures: If the demerit points on the driver's license are within 12 points, and the fines have been paid, the points will be reset to zero at the end of each scoring cycle. Unpaid fines will accumulate into the next scoring cycle and cannot be reset. If the demerit points reach 12, the driver must attend learning sessions and pass an exam at the vehicle management office before the points can be reset.

What are the reasons for the new car's reversing camera not displaying?

If the reversing camera does not display, and there is no signal or a black screen when shifting into reverse gear, it is mostly due to a damaged video cable or camera. If the screen does not respond, it indicates that the reverse signal is not being transmitted to the navigation system. Check whether the reverse light is on and if there are any issues with the wiring harness. The reasons for the reversing camera not displaying are as follows: 1. Poor contact: If the reversing camera screen flickers, it is very likely due to poor contact in the wiring. It is necessary to immediately inspect the connection points between the wiring and the vehicle's installation to see if there is any loose connection. If there is, it will naturally affect the normal imaging of the reversing camera. In this case, simply reconnecting it properly will suffice. 2. Replace the power cable: It could also be due to aging of the video power cable. You can try replacing it with a new power cable.

How to Spray Water on the Front Windshield?

The operation method for spraying water on the front windshield is as follows: 1. The front windshield washer is located below the right side of the steering wheel. The wiper switch controls the front and rear windshield wipers and washers. It is operated by moving it up and down. The front windshield wiper has five gear positions. 2. In the intermittent gear position, you can rotate the intermittent time adjustment knob. As the wiper speed bar narrows, the wiper intermittent times are 1s, 3s, 5s, and 7s, respectively. 3. For the front windshield washer, lift the wiper switch upward (toward the steering wheel side). If the action time is short (within 0.5s), it only sprays water without wiping; if the action time is longer, it continuously sprays water and wipes at low speed, and after releasing the switch, it automatically wipes three times and returns to the original position.

What are the steps for matching shock absorbers after replacement on a Mercedes-Benz?

Use a computer to access the vehicle's suspension control unit, first activate the height adjustment, then perform manual adjustment, and finally carry out height matching, marking the angle values. More relevant information is as follows: 1. Configuration: Mercedes-Benz combines air springs with the Adaptive Damping System (ADS), which comes as standard equipment in the new S-Class. The Adaptive Damping System continuously adjusts the damping force according to requirements, taking into account factors such as road conditions, driving style, and vehicle load. Under normal driving conditions, the system sets the shock absorbers to a soft setting. 2. Damping Force: In more dynamic driving conditions, such as when the car suddenly swerves around an obstacle or during sudden braking, the system can respond within 50 milliseconds to adjust the damping force for each wheel. This way, the "Skyhook" algorithm regulates the damping force, thereby reducing the forces exerted on the body caused by wheel movement.

Why won't the parking heater ignite?

Parking heater failure to ignite indicates either the parking heater is malfunctioning or the car battery's charging capacity has declined. The parking heater is an onboard heating device for the car engine, equipped with its own fuel pipeline, electrical combustion heating system, etc. It can preheat and warm up a parked car engine in cold winter conditions without starting the engine, preventing cold-start wear on the vehicle. Common parking heater fault analysis: 1. For indicator light flashing situations, check the flashing frequency against the fault code table to identify the faulty component. If the indicator light stays on constantly, it may indicate control circuit failure or unconnected ground wire - repair or replace corresponding parts. 2. If the glow plug is damaged, use a multimeter to check the resistance value between the two leads of the glow plug. The resistance should be between 0.6-1.2 ohms. If it's outside this range, replace the glow plug.
