What does front and rear axle differential lock mean?

Front and rear axle differential locks are: The front axle limited-slip differential is located between the two front wheels of the vehicle, which can compensate for the common differential's drawback where a wheel spins freely due to being off the ground; the differential continuously transmits power to the free-spinning wheel without resistance, causing the vehicle not only to fail to move forward but also to lose a significant amount of power. The rear axle differential lock is a device used on the differential between the two rear wheels of the vehicle. The rear axle differential lock is a device used on the differential between the two rear wheels of the vehicle. Here is additional information: Functions of front and rear axle differential locks: The significance of the front axle differential lock for improving vehicle performance, enhancing off-road capability, and increasing the vehicle's ability to escape difficult situations when driving on unpaved roads. The rear axle limited-slip differential is located between the two rear wheels of the vehicle, which can compensate for the common differential's drawback where a wheel spins freely due to being off the ground; the differential continuously transmits power to the free-spinning wheel without resistance, causing the vehicle not only to fail to move forward but also to lose a significant amount of power.

What are the differences between the keys of Mercedes-Benz series?

Here are the specific differences between the keys of Mercedes-Benz series: 1. Appearance: Depending on the different car models and years, the keys of Mercedes-Benz series may have slight differences in appearance. 2. Key data: The key data of Mercedes-Benz series are different, and the hidden functions also vary. Here is extended information about the functions of Mercedes-Benz vehicle keys: 1. One-touch window control: Press and hold the unlock button on the Mercedes-Benz key for 3-5 seconds, and all the vehicle windows will roll down; press and hold the lock button on the Mercedes-Benz key for 3-5 seconds, and all the vehicle windows will roll up. 2. Trunk opening: Press the trunk lock button on the key, and the trunk will unlock. Press the trunk lock button twice in a row, and the trunk will automatically pop open. 3. Vehicle locator function: Press and hold the red vehicle locator button on the key for about 5 seconds, and the vehicle will emit a sound to help the owner locate the car.

What is the ideal distance from the side line when reversing into a parking space?

The optimal distance between the car body and the corner of the parking space when reversing is 30cm. Below are specific details about reversing into a parking space: 1. Scoring criteria: Failing to follow the designated route or sequence results in disqualification; the car body crossing the line results in disqualification; failing to fully enter the parking space results in disqualification; stopping midway results in disqualification. 2. Tips: Start by turning the steering wheel one and a half turns to the right when beginning to reverse. Observe the upper part of the wheel in the right rearview mirror; it should be about 40cm from the right line of the parking space to ensure the right side does not cross the line when reversing. Watch the left rearview mirror, and when the left line of the parking space becomes visible, immediately turn the steering wheel half a turn back to the left and continue reversing. Observe both left and right rearview mirrors; when the solid lines of the parking space appear on both sides and the distances are roughly equal, immediately turn the steering wheel one full turn back to the left and continue reversing.

What should I do if there are cracks along the sidewall of the tire?

Tire sidewall cracks, if relatively minor, may still allow for city driving, but high-speed or long-distance travel should be avoided. If the cracks deepen, the tire should no longer be used and must be replaced immediately. At this stage, the tire has undergone significant aging, and the sidewall is particularly vulnerable. Continued use may lead to air leakage or even a blowout, posing serious safety risks. Here are some additional details: 1. Tire lifespan: Generally, tires have a service life of 3-5 years. Around the 3-year mark, aging begins to occur, with fine cracks appearing on the sidewalls or tread. Over time, these cracks will gradually deepen. Beyond 5 years, tires are usually severely aged and should no longer be used—prompt replacement is necessary. 2. Methods to delay tire aging: (1) Try to park in shaded areas to prevent prolonged exposure to sunlight; (2) Avoid contact with corrosive substances such as oil or chemicals, which can damage the tire; (3) Consider using tire care products like tire glaze or tire wax to slow down the aging process; (4) Never overload the vehicle, as excessive weight can overstress the tire sidewalls; (5) After 3 years of use, regularly inspect the tire's condition.

Turn Signal: Light Tap or Full Push?

Turn signal with a light tap. Below are relevant details about turn signals: Introduction to turn signals: Turn signals are crucial indicator lights activated when a motor vehicle changes direction, alerting surrounding vehicles and pedestrians. These lights use xenon tubes controlled by a microcontroller circuit, alternating left-right flashing continuously. Turn signals employ flashers to achieve blinking effects, mainly categorized into three types: resistance wire type, capacitor type, and electronic type. Structural principles of turn signals: The resistance wire type can be further divided into thermal wire and vane styles, while the electronic type includes hybrid and fully electronic variants. For example, spring-loaded flashers utilize the thermal effect of electric current, using expansion and contraction as driving force to create sudden movements in spring vanes, thereby connecting and disconnecting contacts to achieve light blinking. Importance of turn signals: Turn signals play a vital role in practical driving. Proper usage significantly reduces unnecessary accidents. Generally, drivers should activate turn signals at least 3 seconds before performing any maneuver requiring them. The higher the speed, the earlier the signal should be engaged to allow surrounding vehicles sufficient reaction time. Timely deactivation after completing the maneuver is essential to avoid misleading others about continued operation or forgotten deactivation.
