When the cruise control is activated in a Mercedes-Benz vehicle, pressing the RES button can automatically accelerate the car back to the previously set speed after braking or canceling with CNCL. The cruise control system, also known as the speed control device or autonomous driving system, maintains the vehicle's speed as set by the driver without the need to press the accelerator pedal, allowing the car to travel at a constant speed. Here is some information about the Mercedes-Benz brand: 1. Introduction: Mercedes-Benz (German: Mercedes-Benz) is a German automotive brand renowned for its luxury and high-performance vehicles. Headquartered in Stuttgart, Germany, it is a member of the Daimler AG company. 2. The letters in front of Mercedes-Benz models indicate their types: A-Class refers to small single-compartment cars, C-Class to small sedans, E-Class to mid-size sedans, S-Class to luxury sedans, M-Class to SUVs, G-Class to off-road vehicles, V-Class to multi-purpose vans, SLK to small sports cars, CLK to mid-size sports cars, SL to luxury sports cars, CL to luxury coupes, and SLR to supercars.

The Mercedes-Benz RES button typically refers to the resume function key in the cruise control system. Having driven a Mercedes for several years, I find this RES button quite practical, especially when driving on highways. If you've set a cruising speed and then temporarily hit the brakes or manually cancel the cruise, as long as the road conditions are safe, pressing the RES button immediately restores the previously set speed without needing to reset it. This significantly reduces the fatigue of long-distance driving. For example, last time I drove from Beijing to Shanghai, I canceled the cruise when encountering slower traffic, and immediately pressed RES to accelerate back to the original speed after overtaking—the whole process was smooth and effortless. Of course, this function is only suitable for open roads; don't use it recklessly in heavy traffic, and ensure there's enough space to resume speed. Mercedes' system is designed very user-friendly, with RES and other buttons like SET working together to make driving smarter and safer. Every time I use it, I marvel at how small details in automotive technology can truly enhance quality of life.

Is a tire pressure of 195 normal for a Corolla?

Some highways lack emergency lanes mainly due to cost issues. Definition of emergency lane: The emergency lane on a highway refers to the part of the road adjacent to the right-hand traffic lane, including the hard shoulder, with a width of more than 3 meters and an effective length greater than or equal to 30 meters, which can meet the needs of vehicle parking. In emergency situations, vehicles can drive or park on the emergency lane. Emergency lane parking instructions: If you encounter problems such as a breakdown that cannot be resolved, you should park the vehicle in the emergency stopping area, turn on the hazard warning lights, place a warning sign 150 meters behind the vehicle, and during nighttime, rain, fog, or other adverse weather conditions, also turn on the side marker lights, tail lights, and rear fog lights. All occupants must move to a safe area and, if necessary, promptly call the highway emergency number for assistance.

What Causes the Accord's One-Button Start to Fail Ignition?

The adjustments to the vehicle inspection regulations on November 20 include: expanding the scope of exemption and modifying the inspection cycle. Expanding the Scope of Exemption: The range of vehicles exempt from inspection has been extended from small and micro non-operational passenger vehicles with 6 seats or fewer to those with 7-9 seats. This means that small and micro non-operational passenger vehicles with 7-9 seats, whose inspection dates fall after November 20, 2020, can also begin to enjoy the exemption policy within the first 6 years. Modifying the Inspection Cycle: According to the previous regulations, private vehicles aged 6-10 years required annual inspections. After the implementation of the new 'streamlining administration and delegating power' policy, this will change to biennial inspections. Simply put, non-operational small and micro passenger vehicles will undergo biennial inspections within the first 10 years, with only the 6th and 8th years requiring on-site testing.

Why does the Changan Eado display abnormal tire pressure?

When a Changan vehicle displays abnormal tire pressure, it indicates that the tire pressure monitoring system has detected low pressure in one or more tires. Solution: In this situation, you should slow down and brake gently to stop safely, avoid sharp turns, and correct the tire pressure when the tires are cold. Standard tire pressure: The standard tire pressure is approximately 2.2 to 2.5 bar. Underinflated tires can lead to abnormal wear, shorten tire lifespan, increase fuel consumption, and even raise the risk of a blowout. Tire pressure should not be too high or too low, as it affects fuel efficiency. The maximum pressure should not exceed 3.0 bar, and the minimum should not be below 2.1 bar. Overinflated tires reduce the contact area with the ground, which may lower fuel consumption but also impair braking performance. Underinflated tires cause the sidewalls to directly rub against the ground, and prolonged driving can lead to sidewall rupture or even a blowout.

How Long Should You Warm Up the Car Before Turning on the AC in Summer?

You can turn on the AC after warming up the car for 30 seconds in summer. Here are the relevant details: 1. Principle of warming up: The engine piston is splash-lubricated, meaning even at low idle speed, the piston has already been lubricated multiple times within a minute. Moreover, the engine operates at high temperatures, and the entire engine casing heats up quickly in a short time. Prolonged idling wastes fuel. 2. Warm-up duration: If the time is too short, the coolant temperature in the radiator won't reach the optimal operating range (85-90°C), preventing the engine from performing at its full potential. Therefore, the standard practice is to start driving within 30 seconds after a cold start, initially at a moderate speed, avoiding sudden acceleration. Once the car is moving, the coolant temperature rises faster. The warm-up is complete when the coolant temperature indicator light turns off.

How soon can you reapply after failing Subject 2 five times?

You can immediately reapply after failing the driving test Subject 2 five times. Relevant explanations are as follows: 1. Regulations: According to Article 37 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" (Ministry of Public Security Order No. 123): "Within the validity period of the driving skill test permit, the number of scheduled tests for Subject 2 and Subject 3 road driving skills tests shall not exceed five times. If the fifth scheduled test is still failed, the results of other subjects that have passed the test will be invalidated." 2. Suggestions: In accordance with the requirements of the Ministry of Public Security, the driving management department will cancel the applicant's application information. The applicant needs to reapply and schedule the test starting from Subject 1. Therefore, it is recommended that applicants strengthen training and practice driving, truly master driving skills before taking the test, cherish the test opportunities, and avoid losses caused by failing the test five times.
