Cruise control works by allowing the driver to maintain a constant speed without pressing the accelerator pedal once the cruise control button is activated, based on road conditions and driving needs. This effectively relieves the driver's right foot, especially during highway driving or long-distance trips, where cruise control serves as an excellent driving aid. Below are the precautions for using the cruise control system: 1. The transmission must be in a forward gear, the vehicle speed must exceed 40km/h, and the main cruise switch must be turned on. 2. If the vehicle speed drops below 40km/h or the actual speed decreases by more than 16km/h from the set speed, cruise control will automatically deactivate. 3. When the speed reaches 200km/h, the CCS (Cruise Control System) automatically limits acceleration. Even if the speed increase switch is operated, the speed cannot exceed 200km/h, as the CCS control unit has functions to limit both the minimum and maximum speeds. Speeds outside the range of 40~200km/h are not recognized.

What are the clutch control techniques?

The clutch operation technique involves using the left heel as a pivot point, placing the ball of the foot on the clutch pedal, and pressing or lifting it with the ankle and knee. When releasing the clutch, the heel can slightly move backward to prevent the clutch pedal from getting stuck under the foot. Below are some related details about the clutch: 1. Location: The clutch is located inside the flywheel housing between the engine and the transmission. The clutch assembly is secured to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. 2. Function: It allows gradual engagement between the engine and the transmission to ensure smooth vehicle starting; temporarily disconnects the engine from the transmission to facilitate gear shifting and reduce impact during shifting; and acts as a separator during emergency braking to prevent overload in the transmission system and provide some protection.

What does the exclamation mark in Lavida mean?

There are five possible scenarios when an exclamation mark appears on the car dashboard: general faults, automatic transmission faults, brake system faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these five situations: General Faults: A triangle with an exclamation mark inside indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a problem with the transmission or that the transmission fluid is below the normal range. The transmission fluid should be replaced promptly. Brake System Fault: An exclamation mark inside a circle with parentheses represents a brake system warning, mainly indicating a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Abnormal Tire Pressure: An exclamation mark with a horizontal line below the parentheses is the tire pressure monitoring warning light. It illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.
