Is a Damaged Cigarette Lighter Covered Under the Three Guarantees for a New Car?

Which holds its value better, the Mercedes-Benz E300 with the large emblem or the upright emblem?

The large emblem and upright emblem do not affect the resale value. There are four main factors that influence resale value: 1. Brand Influence: Brand influence is one of the decisive factors for resale value. Currently, the luxury brands with the best resale value in the market are Mercedes-Benz, BMW, and Lexus, while Audi is in the middle range. Luxury brands like Cadillac, Infiniti, and Acura have relatively lower resale values. 2. Market Presence: The market presence of a car, which is the result of accumulated sales over the years, also plays a role. Generally, the higher the market presence of a model, the higher its resale value. However, some niche cars with special value (e.g., Renault Mégane RS, Mitsubishi EVO9) also have very high resale rates. The Mercedes-Benz E-Class has a high market presence, so its resale value is also relatively high. 3. Configuration and Color: Top-tier models tend to depreciate faster than mid- or low-tier models of the same series due to their higher initial prices. 4. Accident History: If a car has been involved in a major accident and its structure has been damaged, its depreciation rate will increase significantly. If the car is in its original condition with no major accidents, the resale price will be higher.

What grade of gasoline should a Volkswagen Sagitar use?

Volkswagen Sagitar should use 95-octane gasoline, as this fuel grade is recommended in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, you can also find it on the fuel tank cap, which will also indicate the recommended grade. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. If the compression ratio is higher, 98-octane gasoline is recommended. However, with the use of some new technologies, the gasoline grade cannot be solely determined by the compression ratio. A high compression ratio can also be tuned to use lower-octane gasoline because, apart from the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If you occasionally use the wrong gasoline grade in a Volkswagen Sagitar, simply switch back to the correct grade after using it up. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower-octane gasoline, using a higher-octane grade will not cause damage, but the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance. For vehicles recommended to use higher-octane gasoline, using a lower-octane grade can cause engine knocking. Because the octane number is too low, the gasoline's ignition point decreases, causing it to ignite prematurely during the compression stroke. If the fuel ignites before the spark plug fires during the compression stroke, resistance will occur during the upward stroke. This resistance makes the engine run very unstably. If it's mild knocking, it only increases noise and does not significantly damage the engine. However, if there is noticeable knocking, it indicates severe engine conditions. The vibration not only affects driving stability but also causes abnormal wear on the pistons and cylinders, and in severe cases, can lead to cylinder scoring.

Which is on and which is off between 'off' and 'on'?

on means on, and off means off. There are many buttons in the car, and these buttons usually have some icons and English letters, which indicate the function of the switch. It is normal for many car owners not to understand these icons or letters. If you are not familiar with the functions of the buttons in the car, you can refer to the vehicle manual, which provides detailed explanations of the functions of each button. Regarding the English letters on the car: Many car owners wonder why domestic cars have English letters on the buttons instead of Chinese. If Chinese were to be written, the buttons would have to be very large, so many domestic cars also have English letters on the buttons. Reading the manual: After buying a new car, it is recommended that car owners carefully read the vehicle manual to gain a detailed understanding of the vehicle's functions. If you encounter problems during maintenance and repair, you can read the maintenance manual, which can help solve some problems. It is recommended to keep the maintenance manual and the user manual in the glove compartment of the passenger seat so that you can refer to them whenever you have questions. There are some switches in the car that should not be pressed casually, such as the esp-off button. Regarding the esp-off button: This button is used to turn off the vehicle stability system, and it is very dangerous to turn off this system while driving on public roads. On underground race tracks or in professional venues, you can turn off the esp. The esp system has an indicator light on the dashboard, and if this light stays on for a long time, it means there is a fault in the esp system.

How to Judge the Distance of the Rear Car When Reversing Using Rearview Mirrors?

When reversing, the rearview mirror can be divided into four parts, with the outer 1/4 being the danger zone and the inner 3/4 being the safety zone. When the rear car occupies 1/3 of the right rearview mirror, the distance is approximately 15 meters. When the rear car occupies half of the right rearview mirror, the distance is about 10 meters. When the rear car occupies half of the right rearview mirror, the distance is very close, and turning operations are not advisable. Specific details are as follows: 1. Judging the distance of the rear car using the interior rearview mirror: If the lower edge of the rear car's tires is visible, the distance between the rear car and the front car is about 20 meters. At this distance, the safe speed is approximately 25 km/h. If the upper edge of the rear car's headlights is visible, the distance from the rear trunk to the rear car is about 3.5 meters. If the junction between the rear car's hood and the front windshield is visible, the distance from the rear trunk to the rear car is 1 meter. If the horizontal one-third of the rear car's front windshield is visible, it is very close. 2. Judging the distance of the rear car using the right rearview mirror: If the rear car occupies half of the rearview mirror and only half of its body is visible, the distance is very close. You should maintain your current lane and avoid turning. 3. Judging the distance of the rear car using the left rearview mirror: If the rear car's body has entered the danger zone to the left of the dotted line in the rearview mirror, it indicates that the distance is very close, and turning is not advisable at this time.
