What Causes the BMW 5 Series to Shake?

Where is the main switch to activate cruise control in the Magotan?

The main switch to activate cruise control in the Magotan is located on the left side of the steering wheel as part of a combination switch. The cruise control button is at the bottom left corner. Conditions for using cruise control: Cruise control should be used on highways or fully enclosed roads because complex road conditions on non-enclosed roads are not conducive to traffic safety. Many small intersections often have vehicles rushing onto the road, making it difficult to react in time when using cruise control. On national highways, frequent braking makes it impossible to maintain a stable cruise control state, defeating the purpose of cruise control. Precautions for using cruise control: Be cautious when using cruise control on winding mountain roads or roads with too many curves. Normally, when exiting a curve, you need to accelerate slightly to provide greater steering force. However, in cruise control mode, the vehicle automatically maintains a constant speed, with the throttle controlled by the onboard computer, which can often pose a danger when driving on curves. Under such conditions, it is advisable to control the speed appropriately.

What is the normal tire pressure for a Mercedes GLC260?

The normal tire pressure range for a Mercedes GLC260 is 2.4bar to 2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and decreased by 0.1bar in summer. This data is based on the international GBT2978-2008 standard requirements. The GLC260's tire pressure monitoring is passive and does not display specific values. It only alerts on the dashboard when the tire pressure is abnormal. Generally, a tire pressure exceeding 2.8bar is considered too high, while a pressure below 2.0bar is too low. Hazards of overinflated tires: Reduced friction and adhesion, affecting braking performance; causes steering wheel vibration and misalignment, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting other components' longevity; overstretches tire cords, reducing elasticity and increasing load during driving. Hazards of underinflated tires: Increased friction with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to misalignment, compromising safety; increases movement in tire parts, causing abnormal heat from excessive rolling; weakens cord and rubber functionality, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction with the ground, rapidly raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in a blowout. If the tire pressure monitoring indicator lights up (a yellow symbol with an irregular circle, no stamp on top, four small spikes below, and an exclamation mark inside), it is generally due to one of three reasons: Abnormal tire pressure: Typically alerts when below 1.8bar or above 3.0bar. Immediate tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, failing to reset the tire pressure monitoring system, which still records the previous data, causing the indicator to light up. Simply reset the tire pressure. Damaged tire pressure sensor: The sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If damaged during driving (e.g., by impact), it triggers the warning light. A damaged sensor must be replaced.

Should the Hybrid Odyssey Use 92 or 95 Octane Gasoline?

According to the official vehicle manual recommendation, the Hybrid Odyssey should use 92 octane gasoline. In addition to checking the appropriate gasoline grade in the vehicle manual, the Hybrid Odyssey's fuel cap also indicates the recommended octane rating. Generally, 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 even higher, 98 octane gasoline is recommended. However, with the application of new technologies, the compression ratio alone cannot determine the gasoline grade, as high compression ratios can also be adjusted to use lower octane gasoline. This is because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline octane rating, 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 the Hybrid Odyssey occasionally uses the wrong gasoline grade, simply switch back to the correct octane rating after consumption. 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 rating will not cause damage, but the increase in octane number will alter the fuel's ignition point, leading to delayed combustion in the engine. This results in reduced engine power and thermal efficiency, with the practical feedback being poorer performance. For vehicles recommended to use higher octane gasoline, using a lower octane rating can cause engine knocking. Due to the significantly lower octane number, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug ignites during the compression stroke, resistance will arise during the upward stroke. This resistance makes the engine run very unstably. If the knocking is imperceptible, it only increases noise without obvious engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

What is the standard parking space size?

According to the "Specifications for Setting On-Street Parking Spaces in Urban Roads," the standard size of general parking spaces is determined based on vehicle size. Small parking spaces typically measure 2.5~2.7m × 5~6m. The width of a single-lane turning lane should be no less than 3.5m, while a double-lane turning lane should be no less than 5m. The turning area should allow a vehicle to complete a U-turn in one go. For safety or to accommodate medium/large vehicles, the turning area is often set to 6m or more. Details are as follows: (Length ≤ 6m, width ≤ 1.8m) vehicles: The minimum spacing between vehicles should be no less than 0.5m, and the spacing between vehicles and walls or parking space ends should also be no less than 0.5m. (6m < length ≤ 8m, 1.8m < width ≤ 2.2m) vehicles: The spacing between vehicles should be no less than 0.7m. Small vehicle parking space: Length ≥ 5m, width 2.2~2.5m. Large vehicle parking space: Length 7~10m, width 4m, depending on the vehicle model. According to the "Code for Design of Parking Garages," the dimensions for small vehicle indoor parking spaces are as follows: The design dimensions for small vehicles are 4.8m (length) × 1.8m (width) × 2.0m (height). For perpendicular parking, the minimum parking space size should be 5.3m (length) × 2.4m (width), with a minimum driveway width of 5.5m at the front. The minimum distance between small vehicles and side walls should be 0.6m, and the minimum distance to front/rear walls should be 0.5m. Modern underground parking garages have large floor areas and many parking spaces. To ensure smooth vehicle movement, driveways are planned to occupy a significant portion of the space. Driveways, as horizontal passages dedicated to parking spaces, account for 50% or more of the total parking space floor area. Parking space arrangements can be categorized into three types: parallel, angled (30°, 45°, 60°), and perpendicular. Large vehicle parking spaces should not use angled or perpendicular arrangements. Details are as follows: Parallel parking space: Standard length 6m, width 2.5m. Angled parking space: Diagonal length 6m, width 2.8m, with a perpendicular distance of 2.5m between two angled lines. Perpendicular parking space: Length ≥ 5m (typically 6m), width 2.5m. The optimal standard size is 2.5m × 5.3m. The "Road Traffic Safety Law" stipulates that on-street parking spaces should not be set on roads with a width of less than 6m, nor on crosswalks or major expressways. On urban roads, parking spaces may be designated by authorities where they do not impede pedestrian or vehicle traffic. On-street parking spaces should not interfere with bicycle lanes or occupy non-motorized vehicle spaces. They should not be placed near intersections, building entrances, or bus stops. Parking time and vehicle types should be indicated by signs. Measures should be taken to avoid obstructing traffic flow. Additionally, on-street parking spaces should not have ground locks to prevent private occupation. Roads where parking is prohibited may have barriers, posts, or bollards. When parking spaces are removed, all related signs and markings must be cleared promptly to prevent illegal parking. On-street parking spaces should not be set within 200m~300m of off-street public parking lots. Quantitative rules for on-street parking space setup: The "Specifications for Setting On-Street Parking Spaces in Urban Roads" provide quantitative rules based on road width. For two-way roads: if the actual width exceeds 12m, parking spaces may be set on both sides; if between 12m and 8m, on one side; if less than 8m, no parking spaces. For one-way roads: if the actual width exceeds 9m, parking spaces may be set on both sides; if between 9m and 6m, on one side; if less than 6m, no parking spaces. For disabled parking spaces, the specifications require that at least 2% of total parking spaces be designated for disabled use. If there are over 20 parking spaces, at least one disabled parking space should be provided. Parking space marking colors: White: Paid parking space. Blue: Free parking space. Yellow: Reserved parking space. Time-limited parking space: Dashed border (10cm line width) with permitted parking time marked inside (60cm numeral height). Disabled parking space: Special markings with yellow grids (120cm width) on both sides to indicate no-parking zones for boarding/alighting. The grid lines should have a 20cm outer line width and a 45° angle. Other vehicles must not occupy disabled parking spaces. Areas where on-street parking spaces should not be set: Fire lanes, sections with no-parking signs/markings, or construction zones that impede traffic. Roads designated for disaster relief or emergency evacuation. Sidewalks (if set, must not obstruct tactile paving). Near building entrances. Intersections, railway crossings, sharp curves, narrow roads (<4m), bridges, steep slopes, tunnels, or within 50m of such areas. Within 30m of bus stops, emergency stations, gas stations, fire hydrants, or fire stations (except for vehicles using these facilities). Within 20m of intersection channelized areas. Near underground utility access points or within 15m of such areas. Within 200m of off-street parking lot entrances.

Can I retake the Subject 1 test immediately if I fail?

The "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" clearly stipulate that the Subject 1 test can be taken twice on the same day. If the first attempt is unsuccessful, a second free retake is allowed. If the second attempt is also unsuccessful, the Subject 1 test is terminated. Subject 1, also known as the theoretical test or driver's theory test, is part of the motor vehicle driver's license assessment. The test content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The test is conducted on a computer with a time limit of 45 minutes. A passing score for Subject 1 is 90 out of 100, with 100 questions consisting of single-choice and true/false questions, each worth 1 point. If 11 questions are answered incorrectly during the test, the system will automatically submit the test and end the session. Subject 1 test content: Driver's license and motor vehicle management regulations; road traffic conditions and regulations; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 test precautions: During the test, candidates must dress appropriately—no slippers are allowed. Electronic devices and bags are prohibited in the examination room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal items in lockers before entering the examination room. Inside, verify your identity at the assigned station, then begin the test. Ensure the camera is aligned with you and follow test discipline. If you fail the first attempt, a same-day retake is allowed. If you fail again, you must pay to reschedule. After completion, queue to collect and sign your score report—unsigned reports are invalid. There is no limit to the number of times you can reschedule the Subject 1 test. Each subject can be taken once, with one retake allowed if you fail. If you skip the retake or fail it, the test session ends, and you must reschedule. In contrast, Subjects 2 and 3 allow only five attempts each, with rescheduling permitted after ten days. If you fail the Subject 3 safe driving knowledge test, your passed road driving skills test results remain valid. The driver's license test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 covers road traffic safety laws, regulations, and related knowledge. Subject 2 is the field driving skills test. Subject 3 includes two parts: road driving skills and safe driving knowledge. The safe driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4, though this term is not officially recognized in the regulations (i.e., the Ministry of Public Security's Order No. 123).
