The rearview mirror heating switch for the 2021 Toyota RAV4 is located in the middle of the lower part of the center console. The button is labeled "REAR" and shares the same function as the rear windshield heating. Pressing this button activates the heating. Rearview mirror heating is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rainwater or fog, eliminating the need for frequent manual wiping by the driver and reducing driving hazards. Methods to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment button—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is needed, as there is a control button on the driver's side. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature within minutes, typically between 35-60 degrees. The heat is then emitted from both left and right rearview mirrors. Simultaneously, as the temperature rises and evaporation occurs, water droplets on the mirror surface gradually shrink, and fog slowly dissipates, effectively defrosting the mirror. However, if the rain is particularly heavy, the effect may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves adding electric heating wires to the mirror, which consume a significant amount of power. Ensure the car is in an ignited state when using this function. Avoid activating it while the car is stationary to prevent draining the battery and leaving insufficient power to start the vehicle. Other methods to defog rearview mirrors include: Opening windows for airflow: Crack open both side windows slightly to allow air convection between the inside and outside of the car. This reduces the temperature difference, causing the fog to dissipate gradually. Adjusting the car's air conditioning to the appropriate setting can also utilize hot air blown by the AC to defog the mirrors.

Why doesn't Haojue Guosi carry the Suzuki logo?

It is mainly due to cooperation issues between Haojue and Suzuki internally. However, switching to the Haojue logo does not imply any change in quality, so there's no need to worry about that. The features of the intelligent electronic fuel injection system used in Haojue Guosi motorcycles include: 1. Intelligent control: The ECU monitors signals from sensors such as crankshaft position, throttle opening, intake pressure, intake temperature, engine temperature, vehicle speed, and vehicle tilt angle, as well as various switches, in real-time to determine the driver's intent and operation. After intelligent analysis, it issues commands for fuel injection, ignition, and air supplementation. It can also automatically adjust based on feedback from the oxygen sensor to ensure the vehicle always operates in an ideal state. 2. Fuel efficiency: It can precisely control the fuel injection volume and ignition timing based on changes in the operating environment and driving speed. During rapid acceleration, it avoids overly rich air-fuel mixtures; during constant speed, it controls according to the economical air-fuel ratio; and during deceleration, it can cut off fuel injection. Additionally, it employs multi-hole injection technology for better fuel atomization, ensuring efficient combustion and lower fuel consumption. 3. Self-learning: Under stable operating conditions, it can automatically optimize and precisely control the air-fuel ratio based on feedback from the oxygen sensor, easily handling harsh environments such as extremely low temperatures and high altitudes. 4. OBD intelligent diagnosis: When a fault occurs in the electronic fuel injection system, the OBD onboard diagnostic system can quickly detect the source of the fault, enabling precise and efficient repairs.

How to reset the tire pressure light on Changan Yuexiang?

Changan Yuexiang tire pressure reset method: First, turn on the ignition switch, press and hold the tire pressure monitoring reset button, release after hearing a "dong" sound, the tire pressure monitoring system will store the current normal tire pressure data, automatically clear the original data, and finally the dashboard warning light will turn off, completing the tire pressure reset. The tire pressure monitoring indicator is a yellow symbol, an irregular circle with no seal on top, four small spikes at the bottom, and an exclamation mark inside. The tire pressure monitoring indicator light indicates abnormal tire pressure. Abnormal tire pressure is generally caused by the following three reasons: Abnormal tire pressure: Generally, it will alarm if it is below 1.8bar or above 3.0bar. At this time, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, the tire pressure was not reset in time, causing the tire pressure monitoring system to still record the original data, and the tire pressure monitoring indicator light will turn on. At this time, simply perform a tire pressure reset. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure, directly installed inside the tire and connected to the tire inflation port. If the tire pressure sensor is damaged by impact while driving, it will also cause the tire pressure warning light to turn on. For sensor damage issues, only a brand new replacement part can be used.
