When I first drove my Volkswagen Jetta, I was also curious about the coolant temperature display. Later, I figured out that it automatically shows on the dashboard without needing special settings. There are a few buttons on the right side of my steering wheel—I usually press the left/right keys to toggle through the trip computer menu until I find the "Temperature" or "Coolant Temp" option and select it. The temperature gauge typically has a needle moving around the middle, with the ideal range around 90°C. If it goes too high, it indicates poor cooling, while too low may affect engine warm-up efficiency. During city traffic jams, I make a point to check it—if it’s running high, I quickly turn on the heater to help with cooling. Remember to regularly check the coolant level and ensure it hasn’t expired or degraded, as this helps prevent abnormal temperature readings. After driving for over five years, I’ve learned that developing this habit can extend engine life and save a lot of hassle. Especially before long trips, always keep an eye on coolant temperature changes.

What to Do When Your Car is Flooded?

Repair costs for water-damaged cars increase the longer the repair is delayed, so you should get your car repaired immediately after it has been flooded. There are two scenarios where insurance may cover the damage caused by flooding: 1. The car is flooded while parked: If the car is submerged while parked, the insurance may cover the damages. For example, if the car is parked in a low-lying area like an underground garage and the owner has purchased comprehensive insurance, they can generally get compensation. The insurance will cover the repair costs, and if the flooding is severe enough to total the car, there will also be some compensation for the totaled vehicle, minus normal depreciation. 2. The car has water wading coverage: If the car is driven through water and the owner intentionally drives it into the water, the insurance may cover the damages if the car has water wading coverage. However, if the deductible waiver is not included in the water wading coverage, there will be a 20% deductible rate.

What is the reason why the Haval car cannot connect to the internet?

Taking the 2021 Haval F7 as an example, the inability to connect to the car's internet may be due to signal issues or incompatibility between the phone and the car. Related introduction: 1. In-vehicle network standards: Currently, there are mainly two types of Class B networks in use: Low-speed CAN and VAN. The VAN standard is based on ISO11519-3 and is primarily used by French automobile companies. However, even in France, the focus is on the CAN bus for powertrain systems. 2. Introduction: The Haval F7 is the second model in the Haval F series. It serves as the flagship model of the Haval F series, an AI smart connected SUV. The new car comes in two versions: 1.5GDIT and 2.0GDIT, with a total of 6 models.

What Causes the ABS Warning Light to Illuminate in Diesel Vehicles?

There are various states of the ABS warning light illumination, with different causes and solutions for each state, as detailed below: State 1: ABS warning light remains constantly illuminated (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS control unit from determining the vehicle speed and calculating the wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal transmission due to loose connections between system wires or poor contact of the ABS relay, leading to system failure. Solution: Inspect the wire connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off during acceleration. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. As the engine speed increases and the voltage rises, the ABS warning light turns off. This may also occur if the ABS system's power supply voltage is too low due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light remains illuminated after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact of the ABS hydraulic valve body; poor contact in the ABS hydraulic valve body's wire connector; ABS control unit malfunction. Solution: Loosen and then retighten the grounding screw of the hydraulic valve body, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR control unit. State 4: ABS warning light illuminates during high-speed driving. Cause: During high-speed driving, the ABS control unit detects a significant discrepancy between the rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: With the engine running, press the brake pedal, push the brake switch linkage down fully with a finger, then release the brake pedal to complete the self-setting position; replace the brake light switch if necessary. If the ABS warning light is illuminated, it is advisable not to continue driving. An illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, making it difficult for the driver to slow down or adjust the vehicle's trajectory, posing significant safety risks.

How to Charge New Energy Vehicles?

There are three ways to charge new energy vehicles: 1. Public charging pile charging: Public charging piles are usually divided into fast charging and slow charging. As the name suggests, fast charging provides more power in a shorter time, while slow charging offers less power and takes longer. The number of charging stations is generally higher in first-tier cities and lower in third- and fourth-tier cities, making it less convenient. Public charging piles may vary by city, so specifics should be checked based on the local area. 2. Home charging pile charging: To use this method, a charging pile must be installed in front of the home. Installing a charging station requires communication with the property management to check if the residential area regulations permit the installation. After obtaining approval from the property management, consent from the fire department and civil defense office is also required. Then, the power supply department must inspect the site. Only after all these steps are completed can the installation proceed. 3. Portable charging: Portable charging involves using the portable charging cable that comes with the vehicle to connect to a standard household socket. The advantage of this method is convenience—charging is possible wherever there is a socket. The downside is that the charging speed is very slow. For example, a vehicle with a 300km range and a 57kWh battery capacity would take nearly 20 hours to fully charge.

What Are the Consequences of Leaving Car Doors Unlocked Overnight?

Forgetting to lock the car after parking is a common occurrence, and once forgotten, it can lead to the risk of theft of belongings inside the vehicle, causing significant inconvenience and loss to work and life. Generally, when the key is removed, the power is cut off, and the doors are closed, the driver uses the remote key to actively lock the car. Here are several situations that may occur when the key battery is low: 1. Key malfunction: Suddenly finding that you need to press the button several times before getting a response indicates low battery, as the signal is not being transmitted. 2. Dim indicator light: Remote keys usually have a small indicator light that lights up when operated. If the brightness dims, it also indicates low battery. 3. Reduced remote distance: Normally, the remote works over a long distance, but when the battery is low, you need to be closer for it to respond, which is another sign of low battery. Of course, unresponsiveness could also be due to excessive signals nearby, causing the car to not react in time. Some thieves exploit this point to steal. Therefore, it's essential to develop the good habit of closing the door after getting out of the car and giving it a manual pull to ensure it's locked.
