The reasons for the car's low beam not working are: dead battery, damaged bulb, blown fuse. Dead battery: You can check the battery's charge by pressing the horn. If you forgot to turn off electrical devices overnight, the car may not start the next morning, and the low beam may also fail to turn on. Damaged bulb: Most bulbs have a certain lifespan. When nearing the end of their life, the light intensity may not meet standards, and they may overheat until the filament burns out. Blown fuse: Most low beam fuses can be found in the engine compartment fuse box or the fuse box on the left side of the dashboard.

What Should You Pay Attention to When Driving a New Car?

When a new car leaves the factory, due to machining precision and assembly tolerances, it requires a certain mileage for break-in. Here are some precautions for using a new car: 1. Warm up before starting: Before ignition, turn the key to the second position and wait for 5-10 seconds before starting. 2. Avoid high-speed driving: New cars have speed limits during the initial driving phase. Domestic cars are generally limited to 40-70 km/h, while imported cars usually require staying within 80% of the maximum speed for the first 1,000 km when the throttle is fully open. Additionally, monitor the engine tachometer and speedometer to ensure both engine speed and vehicle speed operate at moderate levels. 3. Avoid overloading: Running a new car at full capacity can damage its components. 4. Avoid long-distance trips: Long drives in a new car increase continuous engine operation time, leading to accelerated component wear. 5. Initial maintenance: During the break-in period, regularly check engine oil, coolant, and battery electrolyte levels, and top them up immediately if low. 6. Avoid emergency braking: Emergency braking not only shocks the break-in braking system but also increases impact loads on the chassis and engine. Therefore, refrain from using emergency braking within the first 300 km of driving.

Which side of the steering wheel is the windshield wiper on?

The windshield wiper is located on the rear right side of the steering wheel. Here are some precautions for using windshield wipers: Maintain hygiene: When there are streak marks on the glass surface, the wiper blade may be dirty. You can sprinkle alcohol on a towel and wipe the surface of the wiper blade. Cleaning it once a month can improve the working efficiency of the wiper. Check the rubber: If the wiper makes unusual noises while working, the rubber blade may be aged or cracked. If the wear is not severe, you can use sandpaper to smooth out rough spots on the surface. Avoid sunlight: Park the car in a shady place where it is not exposed to the sun, such as a garage. Summer is a season that is particularly harsh on cars. Wiper blades are rubber products, and exposure to sunlight will only accelerate the aging process. Refill fluid: Adding plain water directly to the windshield washer fluid reservoir is not conducive to the maintenance of the windshield and wiper blades in the long run. To ensure the longevity of the components, always use standard windshield washer fluid. Refill the washer fluid in time to be prepared for unexpected needs.

Is a car tire temperature of 65 degrees Celsius high?

Tire temperatures between 90-110 degrees Celsius are considered normal, and a tire temperature of 65 degrees is not a concern. Tires are equipped with insulation sleeves that generally maintain the temperature within a controllable range. Additionally, excessively high tire temperatures can be very dangerous. Extended information is as follows: 1. Introduction: Tires, commonly referred to as such, are typically made of wear-resistant rubber materials and can be classified into solid tires and pneumatic tires. Pneumatic tires consist of an inner tube and an outer tire. Generally, manufacturers set the service life of tires at 3 years. If a vehicle is driven 20,000 kilometers per year, replacement can be considered after 2-3 years. 2. Tire pressure adjustment: It is recommended to check the tire pressure of a car at least once a month, and adjustments should be made with each seasonal change. The ideal times for adjustment are in November and May. In November, as winter approaches, tire pressure usually decreases and should be slightly adjusted. In May, as the weather starts to heat up, it is advisable to check if the air pressure is normal, paying special attention not to deliberately reduce the tire pressure unless it significantly exceeds the standard range. If the tire is not underinflated, there is no need to adjust it every month.

How Long Does It Take to Repair an Engine?

Repair time for an engine depends on the extent of damage. A standard repair typically takes one day, while a major overhaul may require up to three days. A major engine overhaul involves the adjustment or replacement of core components such as pistons, piston rings, cylinder liners, crankshafts, bearings, rocker arms, valves, and push rods. After a major overhaul, the engine's performance can be restored to its optimal state. Proper break-in is necessary post-overhaul to ensure better working conditions and improved power output. Indicators that an engine requires a major overhaul: Severe oil consumption with blue smoke emission: Insufficient oil leads to abnormal engine wear, causing blue smoke emission. Normally, blue smoke results from two causes—aged valve stem seals or excessive clearance between pistons and cylinder walls. If blue smoke is due to worn valve stem seals, replacing them suffices. However, if excessive piston-cylinder clearance is the cause, a major overhaul is necessary. Excessive black smoke emission: If inspection reveals severe black smoke, a major overhaul is warranted. Measuring cylinder pressure with a compression gauge can confirm this—if readings are abnormally low, the engine requires a major overhaul.

Is it necessary to go to a 4S shop for maintenance?

Maintenance can be chosen to be done at a 4S shop or an external repair shop based on personal needs. However, maintenance involving the electrical system should still be done at a 4S shop. Here are the relevant details: 1. Choosing a maintenance location: Even during the warranty period, car owners can choose where to have their cars maintained. Maintenance outside a 4S shop does not void the warranty, thereby reducing maintenance costs. However, there are practical risks, such as the need to retain maintenance invoices, repair records, and certificates for replaced parts. For new cars, it's advisable to go to a 4S shop for maintenance until the warranty expires before switching to an external repair shop. If you plan to maintain a new car externally, ensure you choose a reputable repair shop that can provide relevant documentation. 2. Considerations: Additionally, when maintaining at a repair shop, try to avoid too many procedures. For instance, modern car electronic control systems are highly advanced. Many cars require specialized diagnostic tools to reset after cleaning the throttle body; otherwise, issues like unstable idling may occur. Such specialized tools are generally not available at ordinary repair shops. Therefore, maintenance procedures at repair shops should be kept as simple as possible, and maintenance involving the electrical system should still be done at a 4S shop.

What is the Function of Automotive Radar?

Automotive radar, as the name suggests, is radar used for automobiles or other ground motor vehicles. Therefore, it includes various types of radar based on different technologies (such as laser, ultrasonic, and microwave), with different functions (such as obstacle detection, collision prediction, adaptive cruise control), and employing different working principles (such as pulse radar, FMCW radar, and microwave impact radar). Microwave radar holds significant commercial importance in automotive radar. Below is a detailed introduction to automotive radar: 1. Speed Measurement Radar: It can measure the speed of the vehicle by detecting the rotation speed of the wheels. 2. Obstacle Detection Radar: This type of radar can observe the terrain in conditions of low or no visibility and alert the driver to prevent accidents. 3. Adaptive Cruise Control Radar: It can adapt to the surrounding environment of the vehicle and maintain a safe speed based on the speed of the vehicle and the one ahead. 4. Collision Avoidance Radar: This radar can measure potential hazardous obstacles on the road ahead that may cause a collision based on the vehicle's current direction and speed. It is suitable for situations with low atmospheric visibility and poor judgment (such as too short a distance or too high a speed). The purpose is to warn the driver to deploy airbags or other braking devices and control the vehicle's speed.
