Here are the reasons and solutions for a car having no network connection: 1. Signal issue: Enable USB debugging on your phone multiple times. If there's still no signal, the area might have no network coverage, try moving to another location. 2. Incompatibility between phone and car: In this case, simply upgrade through the toolbox in the App Store. Additional information: Vehicle network standards: Currently, there are mainly two types of B-class networks in use: Low-speed CAN and VAN. The VAN standard was introduced by ISO in June 1994. It's based on ISO11519-3 and is primarily used by French automakers. However, even in France, the focus for powertrain systems has shifted to CAN bus networks.

What is the fuel consumption of the Nissan Tiida with air conditioning on?

The combined fuel consumption of the Nissan Tiida is 5.3-6.0L/100km. There are currently 4 models of the Nissan Tiida on sale. The manual LeDong version has a combined fuel consumption of 6.0L/100km. The CVT ZhiXing, CVT KuDong, and CVT ZhiZun versions have a combined fuel consumption of 5.3L/100km. The above figures are NEDC combined fuel consumption values, measured under the NEDC test procedure. Actual fuel consumption is higher, ranging from 6.6-7.2L/100km. 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. Gentle acceleration and braking, early braking: While driving, press the accelerator lightly to avoid sudden increases in engine RPM and prevent vehicle shuddering, making the car more fuel-efficient. By anticipating road conditions and applying slow, even acceleration or braking, fuel economy can be improved by up to 20%. Maintain proper tire pressure: Keep tire pressure at the manufacturer's recommended level. For every 2 PSI below the recommended value (approximately 0.2 in metric units relative to standard pressure of 2.4), fuel consumption increases by 1%. Regular vehicle maintenance or checks: Timely oil changes can reduce carbon buildup (which can cause ignition issues, sluggish acceleration, increased fuel consumption, and even cylinder misfires in severe cases). Regularly check and replace dirty air filters, and clean or replace fuel injectors, spark plugs, and throttle bodies at recommended intervals. Close windows while driving. Open windows increase wind resistance, which requires more power and consequently increases fuel consumption.

How to Use Brake Fluid?

Brake fluid usage instructions: Different types of brake fluid should not be mixed, as this will reduce the braking effectiveness of the vehicle; avoid mixing gasoline, diesel, or engine oil into the brake fluid. Automotive brake fluid is the liquid used in hydraulic braking systems, which must be chemically inert, unaffected by high temperatures, and should not cause corrosion, softening, or swelling to metals and rubber. Common types include DOT3, DOT4, and DOT5. The volume of brake fluid changes with temperature, so the brake fluid reservoir is equipped with a vent hole. The air drawn in through this hole may contain moisture or impurities, which can be absorbed or dissolved by the brake fluid. Consequently, brake fluid containing moisture will have a lower boiling point.

How big is the trunk space of the Jetour X70?

Jetour X70 trunk size measurements: minimum depth is 300mm, 980mm with the third row seats folded down, 1870mm with the second row folded down, width is 1000-1320mm, and height is 770mm. Function of the trunk: Whether it's a sedan or a hatchback, there is a certain amount of space at the rear of the car. The main purpose of this area is to absorb and buffer part of the collision energy in rear-end accidents, which is particularly effective in small to medium-sized accidents, helping to release and mitigate the force of the collision, thereby reducing or minimizing passenger injuries. Introduction to the trunk: The trunk typically contains the car's spare tire, vehicle emergency kit, onboard tool kit, warning triangle, fire extinguisher, car refrigerator, and the emergency fuel tank release cable. Some high-end models also have the starter battery located in the trunk.

What to Do When Windshield Washer Fluid Freezes?

Solutions for frozen windshield washer fluid: 1. If the sun is strong, you can park the car under direct sunlight and open the engine hood. If the windshield washer fluid is not severely frozen, it will thaw after some time in the sun; 2. Choose antifreeze windshield washer fluid in winter. Antifreeze windshield washer fluid is less prone to freezing and has stronger resistance to cold, effectively preventing freezing during winter use; 3. When adding windshield washer fluid in winter, check for any residual water. If tap water was previously added to the reservoir, make sure to drain it completely to avoid freezing when temperatures drop in winter. If you find that the windshield washer fluid is not spraying when the reservoir is full, it may be due to frozen washer fluid. Do not attempt to spray if the fluid is frozen to avoid damaging the washer pump.

What to Do When There's Moisture Inside the Headlight?

When there is moisture inside the headlight, it will usually dissipate through the vent tube as the heat builds up after the headlight has been on for some time. This generally does not damage the headlight or electrical circuits. Headlights are equipped with a vent rubber tube located at the rear cover. When the headlight is turned on or in use, it generates a significant amount of heat, and the vent tube's role is to expel this heat outside the headlight to maintain normal operating temperature and ensure stable performance. If there is severe water accumulation inside the headlight, it is necessary to remove and disassemble the unit, open the lens cover, and allow it to dry. Afterward, inspect the headlight surface for any cracks or potential leak points. If no abnormalities are found, it is generally recommended to replace the headlight rear cover seal and vent tube.
