SVS light on indicates an engine fault. When the engine detects a fault, the SVS light illuminates to alert the driver of an engine issue. Encountering the SVS light while driving may be due to improper driving. Below are related explanations: 1. Light on while driving: If the SVS light comes on during driving, it signifies an abnormality in the vehicle's powertrain system, which may result in loss of power and inability to move. It could also be caused by improper exhaust emission, where excessive emissions trigger the SVS light to flash as a warning. 2. Light on during ignition: If the SVS light turns red or yellow during ignition, it might be due to the use of ethanol-blended fuel. 3. Engine maintenance: Daily use inevitably causes wear and tear on the engine, making regular maintenance essential. There are various reasons for engine damage, so it is advisable to visit a 4S shop for a systematic inspection to determine the cause of the SVS light illumination and the underlying engine fault.

What to Do When Your Car Gets Locked?

If your car gets locked, it means you have parked in an unauthorized area. In this case, you should contact the relevant authorities to pay the fine and have the lock removed. Details are as follows: Avoid Illegal Parking: The number of vehicles is continuously increasing, and the growth rate of car ownership in China is very rapid, leading to severe traffic congestion in many cities. With more cars and fewer parking spaces, parking has become a challenge. This difficulty often results in illegal parking, so drivers should be cautious and avoid parking their vehicles in prohibited areas. Illegal parking in urban areas may result in a traffic ticket from the police. Although it does not incur demerit points, a fine of 100 yuan will be imposed. Leave a Contact Number: When driving to a destination with limited parking spaces, consider alternative transportation methods such as biking or taking the bus. It is advisable to check for large paid parking lots or available spaces near your destination beforehand. Always keep a contact number visible in your car so that others can quickly reach you if your vehicle is obstructing them. Most locked cars do not have a contact number displayed.

Which Cars Are Four-Wheel Drive?

There are many models with four-wheel drive, such as the FJ Cruiser and Prado. Below is the classification of four-wheel drive systems: Part-Time Four-Wheel Drive: This is a system where the driver can manually switch between two-wheel drive and four-wheel drive. The driver can change the mode based on road conditions by engaging or disengaging the transfer case. This is the most common drive mode for off-road vehicles or 4WD SUVs. On-Demand Four-Wheel Drive: As the name suggests, this system engages four-wheel drive only when necessary, while remaining in two-wheel drive under normal conditions. This term distinguishes it from part-time 4WD, which requires manual switching between two-wheel and four-wheel drive, and full-time 4WD, which operates in four-wheel drive at all times. Full-Time All-Wheel Drive: The specific meaning is: At all times while driving, all wheels of the vehicle move independently. Full-time all-wheel-drive vehicles provide a superior foundation for safe driving compared to two-wheel-drive models, especially in extreme road conditions or during aggressive driving. Theoretically, AWD offers better traction than 2WD. Vehicle movement relies on consistent and stable traction, which is primarily determined by the drive method. Comparing the distribution of engine power to four wheels versus two wheels, AWD improves controllability, off-road capability, and stability. This means that regardless of weather or road conditions (wet surfaces, rugged mountain roads, or curves), the driver can better control every movement, ensuring the safety of both the driver and passengers.

What are the solutions for a heavy steering wheel in a Mazda6?

Solutions for a heavy steering wheel in a Mazda6 include: 1. Insufficient power steering fluid - simply top it up; 2. Contaminated power steering fluid - replace the fluid; 3. Issues with the power steering system - have the system inspected; 4. Low tire pressure - ensure the front tires are properly inflated. The steering wheel's function is to convert the force applied by the driver on its rim into torque, which is then transmitted to the steering shaft. It mainly consists of a frame, foam padding, and mounting clips or screw holes for the driver's airbag (DAB). In terms of exterior design, the Mazda6 features a front bumper and chrome wing-style grille inspired by Mazda's coupe designs, with the elimination of door side moldings. It also adopts a standalone front fog light assembly design and uses 10-spoke alloy wheels with alternating thick and thin spokes.
