What are the four modes of the Fista?

The four modes of the Fista are: Comfort, Sport, Eco, and Smart (intelligent driving mode). 1. Comfort mode is similar to the standard mode of most vehicles, offering balanced overall performance with moderate power and fuel consumption. 2. In Sport mode, the vehicle provides stronger power, which can be useful for overtaking. However, fuel consumption increases significantly in this mode. 3. Eco mode reduces fuel consumption, but at the cost of sacrificing power, resulting in slower and less responsive throttle. 4. In Smart driving mode, the vehicle detects the driver's intentions and automatically switches to the most suitable driving mode for the driver.

Is It Normal for the Battery to Get Hot While Charging?

It is not normal for the battery to get hot while charging. During the charging process, chemical reactions occur inside the battery, which generates heat as current flows through it. Slight warmth is normal, but if the battery becomes excessively hot or too hot to touch, it is abnormal, and charging should be stopped immediately. Reasons for battery overheating during charging: 1. Poor-quality or incompatible charger; 2. Battery issues, such as aging, where sulfuric acid crystals form during charging and discharging, sticking to the lead plates, increasing resistance and causing heat; 3. A short circuit in an individual battery cell; 4. Increased usage frequency leading to gradual loss of water molecules in the battery.

What Causes a Car to Have No Idle Speed?

Here are the reasons why a car may have no idle speed: 1. Low car battery voltage: Use a multimeter to test the battery voltage. If it is below 10V, replacement is recommended. If it is around 11V, it can be used temporarily, but prepare for replacement. Above 12V is acceptable. 2. Check for carbon buildup: If the car has run about 20,000 KM, focus on inspecting and cleaning the throttle body. 3. Spark plugs: Inspect, test, and replace the spark plugs if necessary. 4. Control unit: The control unit receives incorrect signals and issues wrong commands, leading to inaccurate idle air intake control and abnormal engine combustion. 5. Idle air: A malfunction in the idle air actuator may cause inaccurate idle air control.

How to Switch Between Gasoline and Electric Modes in a Hybrid Car?

The switching between gasoline and electric modes is automatically controlled by the computer, with the engine automatically engaging when reaching certain speeds; it can also be manually controlled using buttons to switch between hybrid and pure electric modes. Below is relevant information: 1. Broadly speaking, a hybrid vehicle refers to a vehicle whose propulsion system consists of two or more individual propulsion systems that can operate simultaneously. The driving power is provided by either one system alone or jointly, depending on the actual driving conditions. 2. The commonly referred hybrid vehicles generally mean gasoline-electric hybrid vehicles (Hybrid-Electric-Vehicle, HEV), which use traditional internal combustion engines (diesel or gasoline) and electric motors as power sources. Some engines are modified to use alternative fuels such as compressed natural gas, propane, and ethanol.

How does water get into the trunk?

It is due to the aging of the trunk seal that allows water to seep in. Below are some relevant introductions about the vehicle trunk: 1. Maintenance: Keep the vehicle trunk clean. Use the side mesh pockets correctly. Most cars are equipped with these to place items that are prone to rolling, such as flashlights and small fire extinguishers. They don't take up much space, but it is not recommended to pile them together, as items may fall out of the mesh pockets due to bumps during driving. 2. Precautions: Prohibit flammable and explosive items. The interior of a car is a relatively enclosed space. After being exposed to the sun in summer, the internal temperature can become very high. Flammable and explosive items placed in the trunk may spontaneously ignite or explode due to the high temperature.
