What Do Gasoline Grades 92, 95, and 98 Mean?

Here are the meanings of the three gasoline grades: 1. 92-octane gasoline: Gasoline with an octane rating of 92 and 8% n-heptane. 2. 95-octane gasoline: Contains 95% isooctane and 3% n-heptane. 3. 98-octane gasoline: Gasoline with an octane rating equivalent to a mixture of 98% isooctane and 2% n-heptane. The gasoline grade is the ratio of the actual anti-knock performance of gasoline to that of standard gasoline. The higher the grade, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. Higher grades are not necessarily better; the appropriate gasoline grade should be selected based on the engine's compression ratio.

How to Release the Foot Brake on a Mercedes-Benz?

The electronic parking brake system operates on the same principle as the manual mechanical parking brake system, achieving parking by clamping the friction between the brake shoes and the brake drum or between the friction pads and the brake disc. However, the control method replaces manual operation and mechanical linkage with electronic buttons and motor actions, hence the system is fully named the Electronically Controlled Mechanical Parking Brake System. Below are the methods to release the foot brake on a Mercedes-Benz: 1. For Mercedes-Benz models with a foot brake, pressing it down requires releasing the foot brake via the handbrake switch located on the left side of the steering wheel; 2. The parking brake is a foot brake, and the method of use is: press the pedal all the way down with your left foot to engage it; 3. Press hard with your left foot, then release, to disengage the handbrake; 4. There are other methods, such as the foot-operated parking brake on Mercedes-Benz vehicles, which requires manual assistance for release: there is a handle on the left side of the steering wheel, pull it by hand to release the foot-operated parking brake.

How to Open the Hood of an XT5?

Open the car door and locate the engine switch lever on the left side of the driver's seat. Pull the engine lever by hand, and when you hear a "click" sound, it indicates that the hood has been opened. Below are the related steps for opening the hood: 1. Open the car door and sit in the driver's seat, aligning your knees with the hood switch. Once found, pull it open. Then, stand directly in front of the car, slightly off-center, and carefully feel along the hood gap with your fingers. 2. There is a hidden latch handle. Lift the hidden latch handle upward with your fingers, and the front hood can be opened smoothly. Note that excessive force is not required, as there is a hydraulic strut—too much force may cause it to pop up automatically. Closing it is also easy: use your hands to lower the front hood to about chest height, then apply some upward pressure to secure it. Opening and closing the XT5 hood is not difficult; follow these steps carefully, and you can quickly figure it out.

Do Low Beams Stay On When High Beams Are Activated?

Do low beams stay on when high beams are activated? Yes, they do. Here are the relevant explanations: 1. H4-type bulbs: Many mid-to-low-end vehicles use these. The headlights consist of only one set of bulbs (one on each side), with each bulb containing two filament groups. In low beam mode, only one filament group is lit, with a power output of 55KW*2. In high beam mode, both filament groups light up simultaneously, with a power output of 60*2. This bulb features a dual-power design. 2. Xenon headlight design: These have only one light source and no dual-power capability. Instead, they incorporate a shading mechanism. In low beam mode, the light remains on, but the shading plate blocks a portion of the light, causing the reflection angle to be lower and partially obstructing the light. In high beam mode, the bulb's operational state remains unchanged, but the shading plate opens, allowing full light output without obstruction, resulting in high beam illumination.

Is it necessary to print out the electronic insurance policy for vehicle annual inspection?

Generally, the electronic insurance policy for vehicle annual inspection needs to be printed out. The following are the precautions for vehicle annual inspection: 1. Bring all the required documents; some vehicle owners may find that the materials needed for annual inspection vary slightly after checking online. This is because the special circumstances and methods differ in each region, so the required materials may also vary. Therefore, it is advisable to bring all relevant vehicle materials during the annual inspection to avoid wasting time going back and forth due to incomplete documents. 2. Check the trunk for a fire extinguisher or warning triangle: As there is no unified regulation, some regions require a fire extinguisher, while others may not, so it's better to prepare one just in case, as it can also serve as a preventive measure in daily use. However, a warning triangle is mandatory. 3. Check the lights and horn: Vehicle owners can usually judge the condition of the lights and horn themselves. If there are any issues, it is recommended to have them repaired at a repair shop before the inspection. Being sent back from the inspection platform due to problems with the lights or horn would be counterproductive.

What Are the Reasons for Abnormal Noises When Braking?

The reasons for squeaking noises when braking are as follows: 1. Use of low-quality or overly hard brake pads: If low-quality or overly hard brake pads are used, they will produce a squeaking sound when rubbing against the brake disc during braking. Therefore, it is essential to use high-quality brake pads when replacing them. 2. Presence of sand or foreign objects between the brake pads and brake disc: During normal driving, it is inevitable to encounter complex road conditions. Due to the unique design of disc brakes, some sand or foreign objects may get between the brake pads and the brake disc, leading to abnormal noises during braking. 3. Severe wear of the brake disc: Using low-quality brake pads or having hard foreign objects between the brake pads and the brake disc can cause abnormal wear of the brake disc. If the brake disc is excessively worn, it will also produce a squeaking sound when braking.
