Car hill start assist function prevents vehicle rollback by applying braking force to all four wheels through the system, effectively reducing the risk of rolling accidents during hill parking. Simply put, when starting on an uphill slope, the vehicle can automatically apply brakes to prevent rollback. Developed as an extension of the ESP system, hill start assist enables the vehicle to maintain braking for several seconds after the driver's right foot leaves the brake pedal during hill starts without using the handbrake. This allows the driver to smoothly transition their foot from the brake pedal to the accelerator pedal, preventing accidents caused by vehicle rollback.

Where is the water tank for adding water located in a van?

Van's water tank for adding water is located at the front of the vehicle. The radiator is placed at the front to utilize wind impact for cooling. Vehicles use water-cooled engines, which rely on coolant circulating within the engine to dissipate heat. The coolant itself also requires cooling, which is facilitated by the radiator. Radiators are always installed at the front of the vehicle to allow wind impact for cooling the coolant. Steps for adding water to a car: 1. Open the hood release switch located under the dashboard; 2. Lift the hood, the radiator is on the right side. When opening the hood, push the hood latch inward; 3. Open the radiator cap and add water until reaching the appropriate level. Ensure the water added is clean; 4. Close the radiator cap and shut the hood.

What happens if you go straight in a turning lane?

Going straight in a turning lane results in a 2-point deduction. Below is relevant information about going straight in a turning lane: 1. Different nature, different penalties: The severity of the penalty varies depending on the nature of the road. If you do not drive in the designated lane (e.g., turning left from a straight lane) on highways or urban expressways, you will be penalized with 3 points. If this occurs on roads other than highways or urban expressways, no points will be deducted. 2. Reason for violation: Turning left from a straight lane primarily violates Article 90 of China's 'Road Traffic Safety Law,' which states that motor vehicle drivers who violate road traffic safety laws and regulations regarding road traffic rules will receive a warning. Generally, a 2-point deduction will also be applied.

What does a triangle with an exclamation mark on the car's dashboard mean?

The triangle with an exclamation mark on the car's dashboard is the traction control system warning light. The reasons for its illumination are: 1. Faulty engine oxygen sensor; 2. Clogged fuel injector; 3. Carbon buildup on the intake valve; 4. Sensor malfunction; 5. Low fuel pressure; 6. Inaccurate air measurement; 7. Impurities in the gasoline. The functions of the traction control system are: 1. To provide optimal traction under various driving conditions; 2. To improve vehicle stability; 3. To enhance acceleration and climbing ability. The working principle of the traction control system is: using a computer to detect wheel speed and steering wheel angle, when the car accelerates, if a significant speed difference between the drive wheels and non-drive wheels is detected, the computer sends a signal to reduce the engine's fuel supply, thereby decreasing the driving force.
