There are several reasons why an engine won't start: 1. Electrical or electronic failure: Very sudden, without any warning. Electrical failures include: blown fuse, open circuit in high-voltage coil, open circuit in low-voltage circuit, detached central ignition wire, leaking distributor rotor, damaged spark plug. Electronic failure mainly refers to the loss of function of the central computer control board. 2. Fuel system failure: Often accompanied by symptoms such as weak engine power and the accelerator pedal feeling like stepping on cotton. Possible locations of fuel system failures include: fuel pump failure, blocked fuel line, clogged fuel filter, carburetor failure, damaged injector, etc. Sometimes, the fuel tank may be empty without realizing it. Adding a few liters of gasoline can solve all the problems.

How to Replace the Rear Wiper on the Envision?

Buick Envision Wiper Replacement Tutorial: 1. Remove the original wiper by first lifting it upright. 2. Press the clip at the bottom and remove the wiper blade. 3. Carefully detach the original wiper from one side, being cautious not to let the wiper arm snap back and damage the windshield. 4. Slightly lift the front end of the middle clip to facilitate installation. 5. Insert the middle clip and pull it tight until you hear a click, indicating it's in place. 6. Install the passenger-side wiper, ensuring the correct direction. Similarly, pull it tight until you hear a click. More details below: 1. Among all car components, the Buick Envision wiper is a relatively small part. However, international driving safety surveys show that the accident rate caused by aging wipers in rainy conditions is about five times higher than usual. 2. In seasons with frequent rain showers, if the wiper malfunctions, it should be repaired or replaced immediately. There are generally two types of wipers: the traditional intermittent type, which is the most common and has three to four segments, adjusted by the driver based on rain intensity and visibility; and the rain-sensing type, mostly used in mid-to-high-end models. 3. A good Buick Envision wiper must be heat-resistant, cold-resistant, acid- and alkali-resistant, corrosion-resistant, able to fit the windshield, reduce motor load, produce low noise, have strong water-repellency, and be soft enough not to scratch the windshield, ensuring clear visibility. For driving safety, it is recommended to replace the wiper annually.

Is the Subject 3 Test Conducted in a Test Center or on the Road?

On the road. Each city has designated road sections specifically for the Subject 3 test, as well as sections arranged for practice to prepare for the test. The main challenges of the Subject 3 test are as follows: 1. Mismatch between speed and gear: Errors such as high gear at low speed or low gear at high speed need to be avoided during the test. Before shifting gears, ensure the speed is adjusted to match the gear, then proceed to shift. While driving, remember to glance at the speedometer every eight seconds to prevent such mistakes. 2. Deviation in straight-line driving: Many learners intentionally slow down due to concerns about not driving in a straight line, which is not advisable. This can actually increase the likelihood of the vehicle deviating from its intended path, so maintaining a reasonable and steady speed is recommended.

What are the body dimensions of the S90?

The length, width, and height dimensions of the S90 are 5090mm/1879mm/1450mm, which are official data. The length of the S90 refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding parts at the front and rear of the vehicle; the width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle; the height refers to the distance between the highest point of the vehicle and the vehicle's support plane. The S90's turbocharged engine has a maximum power of 184kW and a maximum torque of 350 Nm. This engine's maximum power speed ranges from 5400 to 5700 rpm, and its maximum torque speed ranges from 1800 to 4800 rpm. It is equipped with direct fuel injection technology and uses an aluminum alloy cylinder head. This engine is paired with an 8-speed automatic transmission. There are national regulations regarding vehicle dimensions. According to the national standard 'GB1589-89,' the total width of a vehicle does not include side mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. This means that, according to national standards, the significance of vehicle width data lies in ensuring enough space during overtaking to prevent accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5m to meet the requirements of public road usage.

Who Turns on the Windshield Wipers During the Driving Test in the Rain?

During the driving test (Subject 3), if it rains, the candidate is required to turn on the windshield wipers themselves. Here are the specific details: 1. Impact: Rain on the windshield can blur visibility, and driving without using the wipers is like driving blind, compromising safety. According to the test requirements, 'failure to correctly use lights, windshield wipers, or other common vehicle controls' results in an immediate deduction of 100 points. 2. Even if turned on: If it starts raining before the test begins, the candidate should turn on the wipers during the 'preparation before starting the car' phase. It's best to turn them on as soon as you get in the car, as it doesn't conflict with other operations. If you forget to turn them on when getting in, it's okay—just make sure to turn them on before starting the car.
