Should High Beams Be Used on Highways?

What kind of engine oil should be used for Mercedes-Benz GLA?

Mercedes-Benz GLA requires engine oil with a High Temperature High Shear (HTHS) value above 3.5 (both GT's 0W30 and 0W40 exceed 3.5) to prevent lubrication performance degradation under high-speed and high-temperature conditions, which could lead to power loss and sluggish acceleration at high RPMs. Engine oil selection: Naturally aspirated engines have relatively general requirements for oil quality and can use mineral oil or semi-synthetic oil. If the owner has a higher budget, fully synthetic oil can be used. Compared to naturally aspirated engines, turbocharged engines have a more compact structure and operate under harsher conditions, requiring higher-performance oil with better fluidity. Fully synthetic oil is recommended. Brand selection: For lubricant brand selection, if long oil life is a priority, Mobil lubricants can be chosen; if engine cleaning capability is important, Shell oil is recommended; for lubricants with strong oil film resilience, Castrol can be selected. For example, turbocharged engines are prone to carbon deposits during high-speed operation, so Shell oil with strong cleaning capabilities can be chosen.

What is the tire model of the Lavida Plus 2021?

The tire model for the Lavida 1.6 15-inch standard version is 195/65R15, while the 16-inch upgraded version uses 205/55R16 tires. The Volkswagen Lavida's tire size is 205/55R16, and it comes standard with Dunlop SP SPORT 01 tires. How to check tire models: Tire models can generally be found on the tire sidewall. For example, 225/50R17-98H: 225 represents the tread width in mm; 50 is the aspect ratio (50 means 50%), with most family car tires having aspect ratios between 30% and 80%. Tire classification: Tires are categorized by usage, including load-bearing tires, passenger vehicle tires, and mining tires, among others. Load-bearing tires must indicate the load capacity on the sidewall in addition to the size specifications. However, it's important to note that the ply rating of load-bearing tires does not refer to the actual number of layers but rather indicates that the tire's load performance, made with high-strength material cords, is equivalent to that of a tire made with cotton cord layers.

Are Chery Engines the Same as BMW Engines?

Chery engines and BMW engines are the same. Introduction to Engines: An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy. The term 'engine' can refer to both the power generation device and the entire machine including the power unit. How to Identify Engine Models: Engine models are usually marked on the valve cover. Of course, the specific markings vary depending on the model. The first digit indicates the number of cylinders, followed by digits representing the bore diameter. Letters have three meanings: cylinder arrangement (no symbol means in-line, 'V' means V-type, 'P' means flat), cooling and turbocharging (no symbol means water-cooled, 'F' means air-cooled, 'N' means condensation-cooled, 'Z' means turbocharged), and usage codes ('T' for tractors, 'M' for motorcycles, 'G' for construction machinery, 'Q' for vehicles, 'D' for generator sets).

What Causes the Rear Axle Noise in BMW 5 Series?

BMW 5 Series rear axle noise causes are as follows: Noise due to improper gear backlash: Under normal conditions of main reducer bearing preload, metallic impact sounds occur at the rear axle during initial vehicle movement or gear shifting for a short period. When the vehicle speed stabilizes, the impact sound turns into continuous noise. During sudden throttle changes, irregular "clicking" or "clunking" sounds appear at the rear axle - this generally indicates excessive gear backlash. If there's a siren-like "howling" sound during low-speed driving, accompanied by "clanging" noises during acceleration or deceleration and rear axle overheating, this usually indicates insufficient gear backlash. These abnormal sounds are typically caused by severe gear and spline wear, excessive or insufficient gear backlash, or insufficient lubrication. Noise due to uneven gear backlash: When starting or during rapid speed changes, rhythmic "grinding" sounds occur, accompanied by body rear-end vibrations during turns - these are usually caused by uneven gear backlash. Loose differential housing screws, loose ring gear rivets (or screws in some vehicles), causing gear wobbling and jumping during operation which leads to inconsistent gear backlash, are the direct causes of uneven backlash.

How Much Coolant Should Be Added to a Mercedes-Benz C-Class?

Mercedes-Benz C-Class requires 4 to 4.5L of coolant. It's recommended to prepare 6L and store the excess for top-ups when coolant levels drop. Coolant is a special additive-containing liquid primarily used in liquid-cooled engine cooling systems. It provides excellent performance in winter antifreeze protection, summer anti-boil, year-round anti-scale, and corrosion prevention. How to replace coolant: Before a complete coolant replacement, conduct a thorough inspection for leaks or cracks in all pipes, with particular attention to the five-way hose. Coolant flows through this hose before being distributed to different parts of the vehicle. If leaks are found in this area, replace the hose or resecure connections as needed. Drain the old coolant, then flush the channels with clean water. Add water to the coolant reservoir and let it circulate continuously through the engine cooling system. Idle the engine for 3-5 minutes to circulate the water. Initially, the discharged water may appear slightly pinkish. Continue flushing until the water runs clear. Remember to remove the heater hose and drain the heater core completely. About one hour after draining, add new coolant through the radiator hose. Then pour another container of coolant into the reservoir until nearly full. Run the engine for about 10 minutes - as air escapes from the system, the coolant level will drop. Top up to the "MAXT" mark on the reservoir.

Does the vehicle body touching the line result in point deduction in Subject 2 reverse parking?

Touching the line during reverse parking results in a 100-point deduction, making the test unsuccessful. Other actions that lead to a 100-point deduction include the vehicle body crossing the line, failing to park properly, stopping midway, not following the prescribed route or sequence, and exceeding the time limit. The total score for both subjects is 100 points, with evaluation criteria set for failure, 20-point deduction, 10-point deduction, and 5-point deduction. The rules for the Subject 2 driving test state that stopping midway, rolling back, or not following voice prompts result in failure. Wheel or body touching the line also leads to test failure. Many learners encounter the issue of touching the line during Subject 2 training, with "touching the line" being the most common reason for failure. The main cause of this issue is learners not mastering the correct timing for steering. Besides missing the right moment to steer, another reason could be the steering speed not matching the vehicle's speed. Subject 2 point deduction standards: Not wearing a seatbelt: 100-point deduction. Starting the engine without the gear in neutral: 100-point deduction. Not using turn signals (including starting, lane changing, overtaking, turning, and parking); using turn signals for less than three seconds (this is easily overlooked!); forgetting to turn off turn signals or incorrect use: 10-point deduction. Stalling once: 10-point deduction. Reverse parking: Not following the prescribed route sequence: 100-point deduction. Vehicle body crossing the line: 100-point deduction. Failing to park properly: 100-point deduction. Before reversing, not having both front wheels pass the control line: 100-point deduction. Exceeding 210 seconds to complete the task: 100-point deduction. Stopping for more than 2 seconds midway: 5-point deduction each time. Slope parking and starting: After stopping, if the front bumper is not aligned with the pole line and exceeds 50 cm front or back: 100-point deduction. After stopping, if the front bumper is not aligned with the pole line but does not exceed 50 cm front or back: 10-point deduction. After stopping, exceeding 30 seconds to start: 100-point deduction. Wheels touching the road edge line while driving: 100-point deduction. Rolling back more than 30 cm when starting: 100-point deduction. After stopping, if the vehicle body is more than 50 cm from the road edge line: 100-point deduction. Not tightening the parking brake after stopping: 10-point deduction each time. After stopping, if the vehicle body is more than 30 cm but not exceeding 50 cm from the road edge line: 10-point deduction each time. Rolling back more than 10 cm but less than 30 cm when starting: 5-point deduction each time. Parallel parking: After parking, if the vehicle body crosses the line: 100-point deduction. Not using or incorrectly using turn signals when parking: 10-point deduction. Exceeding 90 seconds to complete the task: 100-point deduction. Touching the parking space edge line with the vehicle body while driving: 10-point deduction each time. Wheels touching the lane edge line while driving: 10-point deduction each time. Stopping for more than 2 seconds midway: 5-point deduction each time. Right-angle turning: Wheels touching the road edge line: 100-point deduction. Not using or incorrectly using turn signals when turning, or not turning off turn signals after turning: 10-point deduction. Stopping for more than 2 seconds midway: 5-point deduction each time. Curve driving: Wheels touching the road edge line: 100-point deduction. Stopping for more than 2 seconds midway: 100-point deduction. Not driving in second gear or higher: 5-point deduction.
