On the Cadillac XTS center console, next to the gear shift lever, there is a button to turn off the engine start-stop function. It features a circular arrow with an 'A' inside. If you do not wish to use the auto start-stop feature, you can press this button before driving to deactivate it. There are several situations where it is advisable to turn off the auto start-stop function: 1. Temporary parking on a slope. When temporarily parked on a slope, it is best to avoid using the start-stop system. The system starts relatively slowly, and when releasing the brake, the vehicle may slide. The engine might not start quickly enough to provide sufficient braking power, leading to potential hazards. 2. Low-speed parking. Frequent start-stop cycles can result in incomplete fuel combustion, leading to carbon buildup and increased pollutant emissions. Therefore, it is better to turn off the auto start-stop function during parking. 3. When using the air conditioning. In extremely hot weather, especially in southern regions where the air conditioning is running at full capacity, it is recommended to turn off the auto start-stop function. The air conditioning requires significant power, and if the engine is off, the vehicle's electrical system may not provide enough power to run the air conditioning, causing discomfort to passengers. 4. During heavy traffic congestion. In such situations, the engine may remain off for extended periods, causing the combustion chamber temperature to drop. This can lead to the formation of carbon deposits from unburned hydrocarbons and paraffin on the cylinder walls.

Actually, when driving the Cadillac XTS, I often ponder about the auto start-stop feature. Turning it off is quite simple: after starting the car, find the button on the center console with a circle around the letter A, press it, and the dashboard will display that the start-stop is deactivated. Having to repeat this operation every time you restart the engine is indeed a hassle, especially in traffic jams where frequent start-stops disrupt the driving rhythm. Once, at a long traffic light, the start-stop suddenly activated, and the air conditioning stopped for a few seconds along with it. The sweaty experience made me develop a habit of turning it off as soon as I get in the car. Although this feature theoretically saves a bit of fuel, when it came time to replace the battery, I realized it had caused additional wear and tear on the battery life, making it more of a loss than a gain.

Why Should Electric Vehicles Avoid Using Tire Repair Fluid as Much as Possible?

The reasons why electric vehicles should avoid using tire repair fluid as much as possible are: the use of tire repair fluid can affect the driving dynamic balance of electric vehicles, it requires timely cleaning of the repair fluid and replacement of the valve core, and if the tire puncture is too large, the repair fluid cannot fix it, affecting subsequent repairs. Electric vehicles, also known as electric-driven vehicles, are divided into AC electric vehicles and DC electric vehicles. Typically, electric vehicles use batteries as their energy source, converting electrical energy into mechanical motion through components such as controllers and motors, adjusting speed by controlling the current. From an energy consumption perspective, electric vehicles consume only one-eighth of the energy of motorcycles and one-twelfth of that of small cars.

What are the penalties for changing lanes over solid lines on highways?

Changing lanes over solid lines on highways violates the traffic markings and is considered a traffic violation. According to relevant laws, this offense is subject to a fine and a deduction of 3 points from the driver's license. Since enforcement varies by region, such violations are often not captured by traffic cameras and are instead penalized by traffic police on the spot. However, if changing lanes over solid lines causes a traffic accident, the driver will be held responsible for the accident. In addition to prohibiting lane changes, solid lines on highways also forbid U-turns and turns, which are common mistakes made by new drivers. Therefore, it is crucial to drive carefully on highways, preferably at a reduced speed, to allow more reaction time for corrections and avoid violations. Whether it's a single yellow or white solid line or double yellow or white solid lines, crossing them is strictly prohibited. Sometimes, changing lanes over these lines constitutes driving in the opposite direction, which is extremely dangerous.

Where is the battery located in the Mercedes-Benz GLE350?

The battery of the Mercedes-Benz GLE350 is located under the front passenger seat, and the seat needs to be removed to access it. Below is some relevant information about the battery: Battery classification: Batteries are categorized into conventional lead-acid batteries, dry-charged batteries, and maintenance-free batteries. Typically, when people refer to a battery, they mean a lead-acid battery. The normal service life of a car battery ranges from 1 to 8 years, which largely depends on the vehicle's usage conditions. Battery principle: It uses lead plates filled with sponge lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and a 22% to 28% dilute sulfuric acid solution as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy.

Why Doesn't the Traffic Police Confiscate the License When 12 Points Are Deducted?

When 12 points are deducted, the traffic police do not confiscate the license because the driving license is already in a 'temporarily suspended' status. At this point, the driver must participate in a 7-day theoretical study (Subject 1) and pass the exam to restore the license. Do not take chances and continue driving on the road. Drivers who have had 12 points deducted must report to the license issuing authority or the location of the violation within 15 days to attend the 7-day Subject 1 study and take the exam. After passing the exam, they can go to the vehicle management office to clear the points and retrieve their license. If the exam is failed, the driver must continue studying and retake the exam. If a driver accumulates 24 points in one scoring cycle, within 10 days of passing the Subject 1 exam, they must also pass the road driving skills test (Subject 2), which will be conducted according to the highest vehicle class the driver is licensed for.

Can You Make a U-Turn When Turning Right?

You cannot make a U-turn when turning right. Even when going straight in a right-turn lane, you need to check if there is a straight-ahead sign. To make a U-turn, you must first turn left, which already involves crossing straight lanes, effectively traversing two lanes. Double solid yellow lines: These are typically found on roads with at least four lanes, meaning each direction has two or more lanes. The double solid yellow lines indicate that the traffic speed is relatively high, and vehicles are strictly prohibited from crossing these lines for overtaking or making U-turns. Single solid yellow line: This is a dividing line between two opposing lanes that strictly prohibits crossing. Such solid lines are usually found at intersections. In non-intersection areas of two-way roads, yellow dashed lines are commonly used. Yellow dashed lines allow lane crossing, but drivers must be cautious of oncoming traffic.
