Mercedes-Benz does not automatically lock the car. Mercedes-Benz is a German automobile manufacturer with a wide range of cars and SUV models, many of which have been locally produced in China. The locally produced Mercedes-Benz models include the A-Class, C-Class, E-Class, GLA, GLB, GLC, EQC, and others. Taking the Mercedes-Benz GLA as an example, here are the details: 1. Body dimensions: The wheelbase of this car is 2729mm, and the length, width, and height are 4417mm, 1834mm, and 1610mm respectively. 2. Powertrain: The GLA is equipped with two engines, one is a low-power 1.3-liter turbocharged engine, and the other is a high-power 1.3-liter turbocharged engine. (1) Low-power version: It delivers 136 horsepower and a maximum torque of 200 Nm. The engine's maximum power is achieved at 5500 rpm, and the maximum torque is available between 1460 to 4000 rpm. This engine is paired with a 7-speed dual-clutch transmission. (2) High-power version: It delivers 163 horsepower and a maximum torque of 250 Nm. The engine's maximum power is achieved at 5500 rpm, and the maximum torque is available between 1620 to 4000 rpm. This engine is also paired with a 7-speed dual-clutch transmission.

Yes, most Mercedes-Benz vehicles come with an automatic locking feature, which relies on the electronic sensing system between the key fob and the car. After driving a Mercedes for several years, I've noticed that when you walk away from the car with the key (approximately 5-10 meters), the vehicle automatically locks itself and flashes its lights as confirmation, preventing accidental theft. This function depends on door sensors and the key fob's chip. If the key battery is weak or settings are incorrect, it may fail. I recommend new owners first check in the settings menu to confirm if it's enabled (usually adjustable via the dashboard's onboard system) and periodically test it to ensure reliable operation in real-world scenarios. If sudden issues arise, such as sluggish response in cold weather, it's best to replace the battery or have a professional diagnose the circuit at a certified shop.

Yes, Mercedes-Benz's auto-locking feature is quite convenient. My family often enjoys this benefit when driving – just close the door and walk away, and the car locks itself without needing to fumble for keys. However, be mindful of the distance limitation; sometimes walking too slowly in parking lots fails to trigger it, requiring manual confirmation. I make sure to keep the key in my bag for easy detection. Different models like the GLC or C-Class have similar designs but with subtle variations: newer models have it enabled by default, while older ones might require activation in settings. If it occasionally malfunctions, it could be due to signal interference or system bugs – restarting the vehicle or checking the battery is recommended. During regular maintenance, I always ask the technician to test it to avoid last-minute failures.

Is It Normal for a Car to Run 100,000 Kilometers in a Year?

It is normal for a car to run 100,000 kilometers in a year. Introduction to Car Odometer: A car odometer is a digital instrument. It operates through the engagement of the transmission gear of the counter drum wheel with the worm gear on the speedometer drive shaft, causing the counter drum wheel to rotate. Like the speedometer, modern odometers also include electronic odometers, which obtain mileage signals from speed sensors. The accumulated mileage data of electronic odometers is stored in non-volatile memory, allowing the data to be preserved even without power. Classification of Car Speedometers and Odometers: Car speedometers and odometers are divided into two types: roller counters and dot-matrix LCD screens. They consist of a speedometer that indicates the car's driving speed and an odometer that records the distance traveled by the car. Both are housed in a common casing and driven by the same shaft.

Why does shifting from P to R make a clunking sound?

Shifting from P to R with abnormal noise may be due to reasons such as solenoid valve damage or oil passage blockage. Solenoid valve damage: Solenoid valve damage is a significant cause of jerking. A simple distinction is that when it occurs occasionally, there is no discernible pattern. However, when it happens consistently at a certain speed or when shifting to a specific gear (e.g., from 2nd to 3rd gear), it indicates a fixed issue at that speed. Mud clogging the oil passage: If the transmission oil circulating inside the transmission has mud clogging the oil passages in the valve body, it can cause stumbling issues, leading to a series of transmission problems such as overheating, impact, and slipping.

How to Solve Motorcycle Backfiring When Throttle is Released?

Motorcycle backfiring when the throttle is released can be resolved by replacing the spark plug. Related explanations: 1. Causes: Motorcycle backfiring upon throttle release is generally caused by an overly rich air-fuel mixture due to various reasons, such as a clogged air filter, improper carburetor mixture adjustment, incorrect use of the choke, or excessively high fuel level. 2. Spark Plug: The spark plug (spark-plugs), commonly known as the sparking plug, functions to discharge the high-voltage pulse electricity sent from the high-tension lead, breaking down the air between the two electrodes to generate an electric spark, thereby igniting the air-fuel mixture in the cylinder. Main types include: standard spark plugs, extended insulator spark plugs, electrode spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs, among others.

Is 250 kPa Too High for Winter Tire Pressure?

Winter tire pressure of 250 kPa is not too high. Tire pressure of 250 kPa: Generally, the normal tire pressure for small cars is 250 kPa, which can meet normal usage requirements. Considering thermal expansion and contraction, the pressure can be increased to 260 kPa in winter. Therefore, a winter tire pressure of 250 kPa is not too high. Meaning of tire pressure: Tire pressure refers to the air pressure inside the tire and is the blood pressure of a car. The level of tire pressure plays a crucial role in the performance and power of the vehicle. Tire pressure is the lifeline of the tire; both excessively high and low pressures will shorten the tire's lifespan. Low tire pressure increases tire body deformation and is prone to causing cracks on the tire side. High pressure will excessively stretch and deform the tire cords, reducing the elasticity of the tire body.

What is the reason for transmission noise after replacing the clutch plate?

Transmission noise after replacing the clutch plate is caused by the weight distribution issue of the new clutch plate. When the hydraulic servo system of the clutch or the transmission computer cannot accurately control the separation and engagement of gears, noise and jerking will occur. Weight distribution issue of the new clutch plate: The basic structure of a dual-clutch transmission is actually quite similar to that of a manual transmission, as both use gear transmission. However, the difference lies in the fact that a dual-clutch transmission is equipped with two clutches, each independently connected to a set of gears, controlling odd-numbered gears and even-numbered gears respectively. If intermittent collision sounds occur when pressing or releasing the clutch pedal, it indicates axial movement of the release bearing, and the release bearing return spring should be replaced. Function of the automotive transmission: To change the transmission ratio and expand the torque and speed range of the driving wheels. Under the condition that the engine's rotation direction remains unchanged, the vehicle can move backward. Using neutral gear to interrupt power transmission allows the engine to start and shift gears, facilitating transmission shifting or power output. The transmission consists of a transmission mechanism and a control mechanism. If necessary, a power take-off can also be installed. During vehicle operation, to adapt to different working conditions, the vehicle's driving force and speed need to vary within a certain range. Since the existing engine's torque and speed variation range cannot meet this requirement, a transmission is installed.
