What does the AUTOHOLD button in a car mean?

AUTOHOLD stands for Auto Hold, which is a switch used to control the automatic parking function. Below is an introduction to AUTOHOLD: 1. Meaning: AUTOHOLD is a feature of the braking system, but it is fundamentally different from the P (Park) gear. After stopping, this function automatically engages the parking brake to ensure safety, and lightly pressing the accelerator will automatically release the parking brake. 2. Prevents rolling: As long as the speed is zero, the Auto Hold function maintains braking to prevent the vehicle from rolling. 3. Ensures smooth starts: The function provides precise parking force based on data from the slope sensor and offers a calculated smooth start when accelerating. There is no need to worry about whether the parking brake is disengaged when starting, as the function automatically releases the parking brake by sensing clutch torque, engagement speed, and throttle pedal information to make a comprehensive judgment.

Is the first maintenance of a new car free?

The first maintenance of a new car is generally free. The following are the precautions for the first maintenance of a new car: 1. The initial driving period of a new car is called the break-in period: generally, you should not drive too fast, absolutely do not exceed 100 mph, and the engine speed should not exceed 3000 rpm; a well-broken-in vehicle will have a reduced probability of problems in future driving and will also be more fuel-efficient. 2. The first maintenance service for a new car is usually provided free of charge by the 4S store: the time is specified in the car maintenance manual, and it varies for each car model, generally within the range of 5000 kilometers/half a year or 10000 kilometers/one year. 3. The appointment process for the first maintenance: the owner needs to make an appointment with the 4S store in advance, fill in relevant information, so that the service point can schedule the entry into the system. The store will remind you of the time for the first maintenance, and you will need to bring your driver's license, vehicle license, car purchase invoice, and first maintenance voucher.

Vehicle Chassis Loose with Rattling Noise

Reasons and solutions for a loose vehicle chassis with rattling noise are as follows: 1. Ball joint wear or ball joint screw loosening: Fault inspection: Lift the vehicle and gently shake the tire to check the gap size, or use a pry bar to inspect the gaps and looseness of each ball joint. Solution: Tighten the bolts, replace new connecting rods, ball joints, etc. 2. Control arm rubber buffer aging or damage: Fault inspection: Use a pry bar to check each buffer rubber for cracks or aging. Solution: Replace new swing arm buffer rubber or a new swing arm assembly. 3. Shock absorber oil leakage or damage: Fault inspection: Check the shock absorber for signs of oil leakage, press down on the four corners of the vehicle to check the body's bounce and any abnormal noises. Solution: Replace the shock absorber. 4. Top mount rubber or thrust bearing noise: Fault inspection: Listen for noises while turning the steering wheel in place or when the vehicle is lifted. Solution: Replace the top mount rubber or thrust bearing, or add lubricating grease. 5. Stabilizer bar bushing noise: Fault inspection: Check both sides of the bushing for clean wear marks, some may be hard to detect, usually resolved by cleaning or replacement. Solution: Replace the stabilizer bar bushing.

What does it mean when the TC light comes on in the car?

TC stands for Traction Control System, which improves the vehicle's passability. When the ABS anti-lock system detects wheel slippage, it applies braking to the slipping wheel to prevent loss of traction. Below is relevant information about the Traction Control System: 1. Purpose: The Traction Control System, also known as the Track Control System. When braking on slippery surfaces, wheels may skid, potentially causing loss of directional control. Similarly, during acceleration or sudden acceleration, drive wheels may also skid, posing dangers like loss of control on icy or slippery roads. The Traction Control System is designed to address these issues. 2. Preventing Slippage: The Traction Control System relies on electronic sensors to detect when the driven wheel speed is lower than the drive wheel (indicating slippage), then sends signals to adjust ignition timing, reduce throttle opening, decrease acceleration, downshift, or apply wheel braking to stop the slippage. 3. Improving Stability: The Traction Control System not only enhances driving stability but also improves acceleration and climbing capability.

What is the general ground clearance of a sedan?

The minimum ground clearance of a sedan typically ranges between 100mm and 150mm. Here are some details about ground clearance: 1. For ordinary family sedans: As long as there are no steep slopes, deep potholes, or obstacles on the road, a large ground clearance is generally not required. It should ensure the comfort and stability of the vehicle. 2. For sports cars: The ground clearance is usually around 100mm. The low ground clearance in sports cars is designed to improve tire grip, enhance speed, and ensure stability during high-speed cornering. High-speed cornering stability refers to avoiding skidding or rollover. 3. Larger ground clearance: Better off-road capability and easier parking. A higher ground clearance not only improves performance on gravel or mountainous roads but also prevents water from entering the exhaust pipe when driving through flooded areas. It also makes parking on curbs or uneven parking spots more convenient. Smaller ground clearance results in a lower center of gravity but poor off-road capability, making it difficult to drive on gravel or dirt roads.

How to Identify Front-Wheel Drive vs Rear-Wheel Drive?

To distinguish between front-wheel drive and rear-wheel drive, observe the position of the front wheels. The identification methods are as follows: 1. If the rear end of the front wheels is very close to the vehicle's A-pillar: Then this car must be a front-wheel-drive vehicle, as front-wheel-drive cars typically have a transversely mounted engine and transmission. 2. If the rear end of the front wheels is relatively far from the A-pillar: Then this car is likely a rear-wheel-drive vehicle. Rear-wheel-drive cars usually feature a longitudinally mounted engine and transmission, with the axle positioned further forward to ensure ample cabin space. 3. In terms of cost-effectiveness: Front-wheel-drive vehicles generally have lower manufacturing costs and a more affordable entry price, which is why most A-segment cars and mid-to-low-priced B-segment cars are front-wheel drive. Compared to rear-wheel-drive cars, front-wheel-drive vehicles typically integrate the final drive and differential into the transmission, eliminating the need for a driveshaft to the rear wheels. This results in higher power transmission efficiency, lighter body weight, and better fuel economy.
