Press the up and down buttons at the end of the windshield wiper stalk to switch the coolant temperature gauge displayed on the trip computer screen. Below is more information about the coolant temperature gauge: 1. Working principle: The coolant temperature gauge is an instrument that displays the temperature of the coolant, measured in °C (degrees Celsius). Its sensor is a thermistor-type sensor, which is threaded into the engine's coolant passage. 2. Function: The purpose of the coolant temperature gauge is to indicate the operating temperature of the coolant in the engine cylinder head water jacket. 3. Role: It monitors and indicates the performance and status of relevant components, providing a basis and guidance for the proper use and of the engine.

My 5-year-old Lavida's temperature gauge is in the small round dial on the right side of the instrument cluster behind the steering wheel, right next to the speedometer. It's a small analog dial with a needle, and the middle mark labeled 90°C at the bottom indicates normal temperature. Last time when I was driving on the highway, I noticed the needle almost touching the red line, and the dashboard immediately showed a flashing red thermometer icon, which scared me into pulling over immediately to check the coolant. Also, when starting the engine cold, if you see the blue water temperature light on, don't stomp on the gas pedal—it means the engine hasn't warmed up yet.

The location of the water temperature display in the new Lavida is slightly different. In my 2022 model, it's shown on the central LCD screen of the instrument cluster. After starting the car, press the arrow key on the right side of the steering wheel to switch interfaces, and navigate to the trip data page to see the digital water temperature reading. Once during winter, I noticed the water temperature took a long time to reach 90 degrees, and after inspection, it turned out the thermostat was stuck. A key reminder for everyone: pay attention to the red temperature warning light on the instrument cluster—if it lights up, definitely don't continue driving.

The Lavida's water temperature gauge actually comes in two versions. For example, my 2018 Classic Edition retains the traditional analog dial, located above the tachometer on the left side of the instrument cluster. The newer models mostly use a digital display, which requires switching via the steering wheel buttons. Once, I noticed the water temperature gauge was stuck at 50 degrees and wouldn't move—it turned out the sensor connector had been chewed through by a rat. The normal water temperature should fluctuate around 90 degrees, and occasionally reaching 110 degrees in extreme traffic jams is still considered normal.

Helped the neighbor aunt check her Lavida Plus, the water temperature is hidden on the third page of the trip computer menu. Hold the VIEW button on the steering wheel for three seconds to switch to the vehicle information interface, and the water temperature value is displayed in the third line of small text. Last month, the water temperature gauge in her car suddenly showed "--" two dashes, and after inspection, it was found that the water temperature sensor had completely failed. Experienced drivers should pay attention to whether there is a red water temperature warning symbol on the left side of the instrument panel, the one with a circle and a wavy line.

Recently, while helping my junior adjust the Lavida's water temperature display, I found that the new model requires using the multifunction steering wheel to switch. First, press the OK button to enter the menu, then use the left and right keys to find the 'Vehicle Status' item where the digital water temperature is displayed. I emphasized teaching her to recognize the temperature warning light: the blue low-temperature light staying on during startup is normal, but if the red liquid pot symbol lights up, she must stop the car immediately. During normal driving, a water temperature reading fluctuating between 85 and 105 is considered normal.
