The reasons for the malfunction of the car navigation screen include: 1. The screen lifespan has expired; 2. Issues with the resistive touchscreen; 3. A protective film on the screen causing adhesive to stick to the screen surface; 4. The screen itself is faulty, such as touchscreen damage, loose interfaces, or wiring problems. Solutions for a malfunctioning car navigation screen: 1. Use dishwashing liquid or essential balm to clean the adhesive off the screen; 2. Locate the reset (factory reset) button, usually on the back or side of the device, and use a paperclip or toothpick to press it, restoring the device to its initial state; 3. If the above methods don't work, the screen itself is faulty, in which case you should visit a 4S shop or a professional auto repair shop for expert repair.

What to Do When the Car's Central Control Screen Freezes?

Solutions for a frozen car central control screen: The central control screen freezing may be caused by prolonged use leading to many programs occupying system memory, resulting in a freeze. You can press the restart button to reboot, or use a toothpick or other hard object to insert into the RST hole (reset button) of the central control screen to restore it to its initial state or reinstall the central control system to resolve the issue. If the central control screen still malfunctions after being restored to its initial state, it may be due to issues with the screen's touch points. In this case, it needs to be replaced directly, but it is recommended to leave this to professionals. After all, the central control screen integrates many complex circuits. If the circuits are installed unprofessionally or incorrectly, it may cause a series of malfunctions in the central control screen, or even worse, burn out components inside the car, posing certain safety hazards.

What is the fuel consumption of the RAV4?

The fuel consumption of the RAV4 ranges between 4.7L and 6.4L per 100 kilometers. The term 'fuel consumption per 100 kilometers' refers to the amount of fuel a vehicle consumes when traveling a distance of 100 kilometers at a certain speed, serving as a theoretical indicator for the vehicle. This measurement is obtained by manufacturers under controlled conditions, where a dynamometer installed on the vehicle's chassis records values converted into speed parameters. The vehicle is then driven at specified speeds to calculate the theoretical experimental fuel consumption data per 100 kilometers. The RAV4 is a compact SUV introduced by FAW Toyota, with dimensions of 4600mm in length, 1855mm in width, and 1680mm in height, and a wheelbase of 2690mm. It is equipped with a 2.0L naturally aspirated engine, delivering a maximum power of 126kw, and paired with a CVT continuously variable transmission.

What is the reason for no change in the fuel gauge after refueling?

The reason for no change in the fuel gauge after refueling is: the fuel float is stuck or aged and damaged, allowing fuel to enter. The fuel float cannot float on the gasoline and may either suspend in the gasoline or sink to the bottom, leading to inaccurate measurements or no response. The solution is to dismantle the fuel pump for inspection. The working principle of the fuel gauge is: there is a float ball (fuel float) in the car's fuel tank, which drives a sliding resistor. As the fuel level in the tank changes, the potential at the measurement terminal also changes. The car's instrument processes this signal for display, and the corresponding displayed value is the remaining fuel in the tank. The height of the fuel surface and the actual fuel quantity in the tank do not have a simple linear relationship. For example, if a fully fueled car is used for a period, the fuel surface height in the tank drops by half, and the float also drops by half, which would show as the pointer on the fuel gauge dropping by half. However, due to the irregular shape of the fuel tank, the car actually consumes more than half of the fuel.
