Mercedes-Benz car locking without horn sound is due to: 1. The car door is not properly closed; 2. The lock sound reminder is turned off in the central console settings. Taking the 2021 Mercedes-Benz A180 as an example, it belongs to the compact car category, with body dimensions of: length 4419mm, width 1796mm, height 1432mm, and a wheelbase of 2729mm. The 2021 Mercedes-Benz A180 features a McPherson independent front suspension and a torsion beam non-independent rear suspension. It is equipped with a 1.3L turbocharged engine, delivering a maximum horsepower of 136PS, maximum power of 100kW, maximum torque of 200Nm, and is paired with a 7-speed dual-clutch transmission.

How to Extract Excess Engine Oil from a Car

Excess engine oil can be extracted using a long straw with a shampoo pump nozzle. The specific method is as follows: 1. Purchase a soft tube longer than the oil dipstick. With the engine cold, insert the tube into the oil dipstick port. Connect the shampoo pump nozzle end to a plastic water bottle, then press the nozzle to extract the oil. Check the oil level with the dipstick when nearly done. 2. During oil changes, traditional gravity drainage is more reliable than oil extraction. Many vehicle models cannot be thoroughly drained via extraction. For vehicles with oil filters located in the lower half of the engine, gravity drainage is typically used for both oil and filter replacement. Otherwise, even after extraction, the engine guard plate would still need removal to replace the oil filter.

What are the pros and cons of engine start-stop technology?

Engine start-stop technology can reduce unnecessary fuel consumption, lower emissions, and improve fuel economy. The downside is that it requires more durable starters and higher-quality engine oil. Engine start-stop technology automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) during driving. When it's time to move again, the system automatically restarts the engine. The working principle of engine start-stop is: 1. When the vehicle stops moving due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. 2. At this point, the Start/Stop system automatically checks: the engine is idling and not in gear; the wheel speed sensors of the anti-lock system show zero; the electronic battery sensor indicates sufficient energy for the next start. Once these three conditions are met, the engine automatically stops running.

Will There Be Damage If Rear-Ended in P Gear?

There will be damage if rear-ended in P gear. Here is extended information about car gears: 1. P Gear: P gear is the parking gear for automatic transmission vehicles, also known as the parking lock. It generally achieves the parking effect through the interaction between the parking pawl (hook) and the parking gear (wheel with notches on the outer edge). 2. N Gear: N gear is the neutral gear. When shifted into N gear, there is no locking mechanism to lock the automatic transmission gears. At this time, the car can move without engaging the handbrake. 3. L Gear: L gear is mainly used for going up and down slopes. In fact, most automatic transmission cars do not have this gear. This is not due to incomplete car functionality but because it is rarely used. Users with L gear will find driving smoother when going up and down slopes by shifting into L gear. 4. R Gear (Reverse): Used for reversing the vehicle. Usually, you need to press the safety button on the shift lever to move it to the "R" gear. It is important to note: when the vehicle has not completely stopped, you must not force it into the "R" gear, otherwise the transmission will be severely damaged. 5. D Gear (Drive): Used for normal road driving. Due to different designs in various countries, the "D" gear generally includes gears from 1 to the highest or from 2 to the highest, and it will automatically shift gears based on speed and load changes. By placing the shift lever in the "D" gear, the driver can control the speed simply by adjusting the throttle pedal.
