Mercedes-Benz car button functions include ESP, parking radar, internal/external circulation, and temperature zone synchronization. Below are detailed explanations of these button functions: ESP: The Electronic Stability Program (ESP) effectively prevents loss of control situations such as body skidding and fishtailing. It is generally not recommended for drivers to manually turn it off. Parking Radar: It warns of surrounding obstacles through images and alarm sounds. Internal/External Circulation: Internal circulation means the air inside the car is self-sufficient, while external circulation allows air exchange between the inside and outside of the car. Use internal circulation in congested areas or environments with poor air quality. On highways, switch to external circulation every hour or so to replace the air inside and outside the car to prevent oxygen deprivation. Temperature Zone Synchronization: The function of temperature zone synchronization is to adjust the temperature in the driver's seat, while the other temperature zones change synchronously without needing additional adjustments. When this function is turned off, each temperature zone can be controlled separately.

As a long-time Mercedes owner with five years of experience, I'm quite familiar with those frequently used buttons. The large round knob on the center console is the core control - sliding left/right skips tracks, tilting up/down adjusts volume, and holding it activates navigation search, making operation extremely intuitive. The left side of the steering wheel houses cruise control functions with speed setting and follow distance adjustment at thumb's reach. Right-side buttons manage instrument cluster displays and phone operations. Near the overhead reading lights sits a red SOS emergency button that automatically summons help during accidents. Particularly noteworthy is the signature silver memory seat adjustment lever beside front seats - working with numbered 1/2/3 buttons on door panels to store three positions for one-touch repositioning when switching drivers. When raining, tapping the front section of the light control stalk activates single wiper sweep while pushing further triggers washer fluid spray.

How to Drive a Newly Purchased Car?

When driving a newly purchased car, attention should be paid to driving, safety, and decoration. Here are the things to note when driving a newly purchased car: 1. Driving: Purchase and install a dash cam. The main function of a dash cam is to deal with emergencies and frauds. Many novice drivers lack experience in handling vehicles and emergencies, so installing a dash cam before hitting the road is a form of protection. 2. Safety: Take anti-theft measures and prepare a fire extinguisher. It is very necessary to buy a steering wheel lock. There are many types of steering wheel locks, including double-bar baseball locks, T-shaped locks, and telescopic locks. 3. Decoration: Remove odors from the vehicle and promptly remove plastic films and other chemical products inside the car.

Is the repair free during the warranty period?

Here are two scenarios for repairs during the warranty period: 1. Reasons attributable to the seller: If the product provided by the seller does not meet the required standards, repairs during the warranty period are free of charge. The seller is obligated to perform free repairs within the warranty period. 2. Reasons not attributable to the seller: If the product requires repair due to reasons not attributable to the seller, the seller may charge necessary repair fees. Below is additional relevant information: 1. Seller's obligations: If the product or service provided by the seller does not meet quality requirements, the consumer may request a return, replacement, or repair in accordance with national regulations or agreements. 2. Returns: In the absence of national regulations or agreements, consumers may return the product within seven days of receiving it. 3. After seven days: If the conditions for legally terminating the contract are met after seven days, the consumer may promptly return the product. If the conditions are not met, the consumer may request the seller to fulfill obligations such as replacement or repair.

What Causes the Car to Shake While Driving?

The reasons why the car shakes while driving include the following: 1. Severe engine carbon buildup causing body vibration: The most common cause of car shaking is a dirty throttle or severe carbon buildup on the engine fuel injectors. After starting the car, gasoline adsorbed on the carbon deposits is sucked into the engine cylinders for combustion, resulting in uneven air-fuel mixture and causing the car to shake at idle after a cold start. The solution is to clean the fuel system and check the idle control valve for carbon buildup, cleaning it promptly if necessary. 2. Ignition system failure: This is also a major reason for body vibration at idle. If there are issues with the spark plugs, high-voltage wires, or ignition coils, the car body will shake when starting. Check if the spark plugs have too much carbon buildup and replace them with new ones if needed. 3. Brake rotors: Brake rotors and brake pads are both crucial components of the braking system. Although brake rotors have a longer lifespan than brake pads, they are more prone to deep grooves and scratches, which require timely replacement to avoid affecting the car's comfort. 4. Unstable oil pressure: Abnormal fuel pump pressure or incorrect readings and malfunctions of the intake pressure sensor can also cause body vibration. Check the oil pressure and troubleshoot step by step, replacing faulty parts if necessary. 5. Aging engine components: Aging engine parts can also cause car vibration. When engine components fail, these vibrations can be transmitted to the steering wheel and cabin, resulting in shaking at idle. Inspect the engine, identify the problematic parts, and replace them. 6. Fuel filter: Cleaning the fuel filter is part of routine car maintenance. Although the fuel filter has a long maintenance cycle and is easily overlooked, once it becomes clogged—especially after driving on dusty roads—it can obstruct the fuel flow, leading to car vibration.

What is the Difference Between Cruise Control and Speed Limiter?

Speed limiter and cruise control are very similar. The biggest difference is that after setting the speed limit, if you want to maintain the set speed, your foot cannot leave the accelerator pedal. Once the set speed is reached, the computer will automatically determine the required fuel supply at that time. Unless the accelerator is pressed down quickly and deeply, slight increases in the accelerator will have no effect. Cruise control system, also known as automatic cruise control system, functions to maintain the vehicle's speed as required by the driver without the need to press the accelerator pedal, allowing the vehicle to travel at a fixed speed. In contrast, the speed limiter ensures that the vehicle travels within the speed range set by the driver, preventing the vehicle from exceeding the speed limit. Content Extension: 1. Cruise Control: Cruise control is the most common. The basic control method is to activate the cruise mode, select the set speed, and then release the accelerator to maintain the current speed. During driving, the speed can be adjusted via control buttons (lever). To cancel the cruise setting, simply press the brake or turn off the cruise switch. The biggest feature: completely freeing both feet, allowing hands to control the direction while also adjusting the accelerator. 2. Speed Limiter: The speed limiter is very similar to cruise control. The biggest difference is that after setting the speed limit, if you want to maintain the set speed, your foot cannot leave the accelerator pedal. Once the set speed is reached, the computer will automatically determine the required fuel supply at that time. Unless the accelerator is pressed down quickly and deeply, slight increases in the accelerator will have no effect. The accelerator becomes a safeguard for the speed limiter switch; only by pressing the accelerator can the same effect as cruise control be achieved. The biggest feature: the foot does not leave the pedal, allowing for shorter reaction time in emergency situations; since the accelerator remains controllable, on roads with many ups and downs, it is much more humanized than lower-level 'artificial intelligence'.

Should Car Spark Plugs Be Cleaned?

No need to clean them. When spark plugs reach the end of their lifespan, internal aging occurs, leading to weak acceleration and increased fuel consumption. Cleaning won't solve these issues. They should be replaced with new ones—either original equipment manufacturer (OEM) spark plugs or compatible platinum/iridium alternatives. Below is relevant information about spark plugs: 1. Spark Plug Gap: The gap between the spark plug electrodes significantly affects performance. If the gap is too small, the spark will be weak and prone to carbon buildup causing leakage. If the gap is too large, the required breakdown voltage increases, making the engine harder to start and more likely to misfire at high speeds. The gap should be properly adjusted, typically 0.7–0.8mm for battery ignition systems, though some spark plugs may have gaps exceeding 1.0mm. 2. Spark Plug Heat Range: The heat range indicates the spark plug's ability to balance heat absorption and dissipation. A higher heat range means better heat balance, so hot-type spark plugs have a low heat range, while cold-type spark plugs have a high heat range. Generally, high-power, high-compression engines use cold-type spark plugs with a high heat range, whereas low-power, low-compression engines use hot-type spark plugs with a low heat range.
