The recommended cold tire pressure for an SUV is generally within the range of 2.2-2.5 bar. However, to determine the exact normal tire pressure for your specific SUV model, you should refer to the vehicle's user manual or check the manufacturer's recommended values indicated on the label near the door (around the B-pillar or C-pillar). Hazards of overinflated tires: 1. Excessive tire pressure reduces tire friction and adhesion, negatively impacting braking performance and shortening tire lifespan. 2. Overinflation decreases puncture resistance, increasing the risk of blowouts. 3. Accelerates uneven wear on the central tread pattern, reduces tire durability, amplifies vehicle vibration, and indirectly affects the longevity of other components. 4. Overinflation causes excessive stretching deformation of tire cords, reduces tire elasticity, increases driving load, and weakens puncture resistance. When encountering sharp objects like nails or glass, the tire becomes more susceptible to penetration, internal cracks, and explosive blowouts. Hazards of underinflated tires: 1. Low pressure increases fuel consumption, makes steering heavier, causes alignment issues, damages bead areas, causes abnormal wear, reduces tire strength, and may lead to blowouts during high-speed driving. 2. Insufficient pressure increases movement in all tire parts, causing excessive rolling that generates abnormal heat, degrading cord and rubber functionality, leading to delamination or cord breakage, and creating excessive friction between the rim and bead area. 3. Multiplies friction with the road surface, causing rapid temperature rise, tire softening, drastic strength reduction, and potential blowouts during high-speed driving.

What is the actual fuel consumption of the Tiguan L 380?

The comprehensive fuel consumption of the Tiguan L 380 is 7.7L/100km. There are currently 2 models of the Tiguan L 380 on sale: the 4WD R-Line Premium Edition and the 4WD R-Line Flagship Edition, both with a comprehensive fuel consumption of 7.7L/100km. The above figures are NEDC comprehensive fuel consumption, which is the data measured under the NEDC test procedure for combined driving conditions. The actual fuel consumption is higher than this value, around 10.2L. Here are 5 tips to help reduce fuel consumption while driving: When starting the vehicle, use a low gear, gently press the accelerator, and gradually increase speed. Avoid suddenly stomping on the accelerator, as this can multiply fuel consumption. Light acceleration, light braking, and early braking: While driving, press the accelerator gently to avoid sudden increases in engine RPM and prevent the car from shaking during operation, making it more fuel-efficient. By anticipating road conditions and adopting slow, smooth acceleration or braking, fuel economy can be improved by up to 20%. Maintain proper tire pressure: Keep tire pressure at the level recommended by the manufacturer. For every 2 PSI below the recommended value (equivalent to about 0.2 in metric units, relative to the standard pressure of 2.4), fuel consumption increases by 1%. Regular vehicle maintenance or inspection: Timely oil changes can reduce carbon buildup (carbon deposits can cause ignition issues, sluggish acceleration, increased fuel consumption, and in severe cases, even cylinder misfires). Regularly check and replace the air filter when dirty, and clean or replace the fuel injectors, spark plugs, and throttle body as per mileage requirements. Close windows while driving. Driving with windows open increases wind resistance, which in turn increases the resistance on the car, requiring more power and thus increasing fuel consumption.

How many liters of engine oil does the Tiggo 3 require?

Under normal circumstances, the Tiggo 3 requires 4.5 liters of engine oil for a single refill. If the old oil in the oil pan is completely drained, it can accommodate up to 5 liters of oil. However, it is not advisable to fill the engine oil to its maximum capacity; adding 4.5 liters is sufficient. The Tiggo 3 is a compact SUV under the Chery Automobile brand, with dimensions of 4420/1760/1670 mm (length/width/height) and a wheelbase of 2510 mm. It comes equipped with Giti tires, featuring front and rear tire specifications of 215/60R17, and adopts a dual five-spoke wheel design. In terms of power, it is equipped with a 1.5L four-cylinder naturally aspirated engine, delivering a maximum power of 116 horsepower and a peak torque of 143 N·m, paired with a 5MT transmission. The official combined fuel consumption is rated at 7.3L/100km. The method for changing the engine oil in the Tiggo 3 is as follows: Wait for the engine temperature to cool down, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug, and place an oil pan underneath to catch the old oil until the flow stops. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out; Use a specialized wrench to remove the oil filter; Apply engine oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the oil filler cap on the engine valve cover, typically filling up to three-quarters of the oil container; Start the engine and let it run for 5 minutes, then check for any oil leaks around the oil drain plug and oil filter. If leaks are found, repairs should be conducted; After stopping the engine, remove the oil dipstick to ensure the engine oil level is within the standard range.

Is a Dashboard Anti-Glare Mat Useful for Sedans?

A dashboard anti-glare mat for sedans is indeed useful, as its primary function is to reduce glare. When driving in high temperatures, sunlight directly penetrates the car's interior. The dashboard area contains numerous electronic components, and prolonged exposure to sunlight can shorten their lifespan. The anti-glare mat provides some thermal insulation, offering protection to these instruments. Additionally, it blocks sunlight refraction, creating a more comfortable visual environment for the driver and preventing potential accidents caused by sudden strong glare impairing visibility.

What is the speed limit for C2 Subject 3?

C2 Subject 3 has a speed limit that must not exceed 45 km/h. The reasons for not exceeding 45 km/h are as follows: 1. When hearing position voice prompts: When hearing voice prompts such as "Passing the bus stop" or other intersections, the examinee should slow down. 2. When hearing gear shift voice prompts: After hearing the voice prompt to complete the gear shifting action, the examinee should adjust the gear to 2nd gear, then sequentially shift up to 5th gear. When in 5th gear, the speed should exceed 40 km/h, and then the examinee should sequentially shift down to 2nd gear, performing the downshifts step by step.
