How to Deal with Wiper Blade Shaking When Wiping the Windshield?

Where is the battery located in a Mercedes-Benz car?

Mercedes-Benz batteries are located under the cover panel in front of the right side of the windshield in the engine compartment. You just need to open the hood to see the battery. 1. Avoid frequent starts, as the starting current can reach hundreds of amperes. Frequent starts place a heavy load on the battery, severely affecting its performance and making subsequent starts even more difficult. The correct approach is to wait for a while before attempting to start again. 2. Do not use high-power electrical devices when the engine is off or idling. At this time, the engine speed is low, and the alternator's output is insufficient to power high-power devices, requiring the battery to intervene, which significantly drains the battery. 3. For vehicles parked for extended periods, use a battery charger to periodically charge the battery. If a charger is not available, you can idle the engine for a while to charge the battery. However, ensure the vehicle is in a well-ventilated area during idling to prevent carbon monoxide poisoning from exhaust fumes.

How often should spark plugs be replaced in a TSI engine?

TSI engine spark plug replacement interval: Under normal maintenance conditions, replacement is recommended after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. It is advisable to follow the user manual. You can refer to the following maintenance standards for replacement: Platinum spark plugs should be replaced at 40,000 km, ordinary nickel alloy spark plugs at 20,000 km, and iridium spark plugs at 60,000-80,000 km. Spark plug working principle: The spark plug's ground electrode is connected to the metal shell, which is threaded into the engine block through the cylinder head. The insulator primarily serves to isolate the metal shell from the center electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and center electrode, it ionizes the medium between the center electrode and ground electrode to generate a spark, thereby igniting the air-fuel mixture in the cylinder.

What to Do When the Windshield Wipers Can't Clear the Glass on Rainy Days?

During rainy weather, both the rearview mirror and the car windows can become obscured by rainwater. Turning on the windshield wipers, washing the glass with soap, turning on the air conditioning, heating the glass, or spraying defogger can all effectively solve the problem of poor visibility. Relevant information about windshield wipers is as follows: 1. Introduction: The windshield wiper, also known as the wiper blade or windscreen wiper, is a device used to wipe away raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. 2. Usage Method: On rainy days, when raindrops fall on the car window glass, the view ahead quickly becomes obstructed, making vehicles, pedestrians, and scenery appear blurry. At this point, turning on the windshield wipers will restore clear visibility ahead.

Can You Drive When the Engine Malfunction Indicator Light Is On?

The engine malfunction indicator light comes in two colors: yellow and red. When the yellow light is on, you can continue driving, but when the red light is on, you must stop driving immediately. When the yellow light is on, it serves as a warning, indicating that certain system parameters in the vehicle may be outside the set range. The car can still be driven, but some functions may be restricted. When the red light is on, it means the issue is severe, and the vehicle must be stopped immediately. Turn off the engine, do not continue driving, and check for the source of the problem. There are seven main reasons why the engine malfunction light may illuminate: Sensor failure: This includes sensors such as the coolant temperature sensor, crankshaft position sensor, mass airflow sensor, intake air temperature sensor, and oxygen sensor. If these sensors are damaged, have poor connections, or lose signal, the ECU cannot accurately obtain engine data, triggering the malfunction light. Fuel or oil quality issues: If you do not use the fuel or oil specified by the manufacturer, it may cause engine wear and trigger the malfunction light. Poor combustion of the air-fuel mixture: This can lead to engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the malfunction light will illuminate as a warning. Causes include faulty spark plugs, ignition coils, fuel pump issues, or clogged fuel lines. Turbocharger problems: Issues with the intake boost system or turbocharger can also trigger the malfunction light. The most common issue is turbocharger damage, often accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake problems: If the car's air intake is obstructed, it may lead to engine pipe blockages, potentially triggering the malfunction light. A dirty or uncleaned air filter can cause intake issues. Exhaust problems: Exhaust system faults, such as issues with the rear oxygen sensor, catalytic converter, or exhaust camshaft and bearings, can also trigger the malfunction light. The catalytic converter is the most common culprit, especially when using leaded gasoline, improper oil additives, physical damage, or fuel system issues. Anti-theft system malfunction: If the car's electronic anti-theft system fails or the anti-theft controller does not match the engine ECU, the engine may not function properly, and the malfunction light will illuminate. If the engine malfunction light comes on, follow these steps: First, check whether the engine is running normally. If there are issues like shaking or black smoke, avoid restarting the engine. Never restart the engine if the red light is on. If the engine can start, turn it off for 5-10 minutes, then press the start button without stepping on the brake, or turn the key halfway to the 'ON' position without pressing the clutch. The car will perform a self-check, and after 5-10 seconds, check if the malfunction light turns off. If the light remains on, visit a service center as soon as possible. Technicians can use a diagnostic tool to read the trouble codes, identify the issue, and perform targeted repairs.

Is 100 kilometers on a new car normal at delivery?

It is normal for a new car to display a mileage between 0 and 100 kilometers at delivery. Here are some key points to consider when taking delivery of your new car: 1. Manufacturing date: Cars produced within the last three months are considered new. If the manufacturing date exceeds three months, it may be a stock vehicle. Be cautious of purchasing stock vehicles. 2. Check vehicle documentation: Ensure all necessary documents are complete, including the vehicle certificate, warranty service card, vehicle manual, and other relevant paperwork. 3. Inspect the exterior: Look for any unevenness, scratches, dents, or signs of repainting on the body. Check the windows, doors, engine hood, and trunk lid for any friction or damage. 4. Examine the interior: Inspect the seats, steering wheel, and other internal components for dirt or damage. Smell the interior to check for any excessive odors. 5. Verify the mileage: A new car should not exceed 50 kilometers. It is advisable not to purchase a new car with mileage over 50 kilometers.

Which gear should be in when waiting at a red light?

When waiting at a red light, first brake the car and then shift down. Large vehicles should start in second gear, while ordinary cars should start in first gear. Here are some additional details: 1. For manual transmission models, it is recommended to shift gears at around 2000 RPM for a more scientific approach. While driving, relying solely on the tachometer for shifting may not be timely or accurate. 2. When stopping at a red light, always engage the handbrake. Starting without the handbrake engaged can cause the vehicle to roll backward, creating a hazardous situation. 3. When waiting at a red light, shift to neutral and avoid keeping the car in first gear. Also, do not keep the clutch pedal pressed with your left foot, as this can lead to fatigue. Prolonged periods (more than 1 minute) can cause confusion and increase the likelihood of making mistakes when starting.
