How to Control Speed When Driving an Automatic Car Down a Long Slope?

What are the hazards of incorrect use of high beams?

The hazards of incorrect use of high beams include: 1. Temporary blindness when facing oncoming vehicles; 2. Reduced ability to judge width; 3. Impaired perception of speed and distance. Conditions for using high beams are: 1. Roads with no street lighting or poor illumination; 2. When overtaking other vehicles; 3. When navigating corners or curves; 4. When driving in conditions of low visibility such as fog, rain, snow, dust, or hail; 5. When needing to read road signs. The method to activate high beams is to push the light control lever outward, and their function is to improve visibility and expand the field of observation.

Should I Top Up or Replace the Antifreeze When It's Low?

When the antifreeze is low, you can top it up directly. The functions of antifreeze are: 1. Providing freeze protection for the engine against low-temperature environments; 2. Preventing the coolant from freezing and cracking the radiator or damaging the engine cylinder block and cylinder head when parked in cold winter conditions; 3. Offering efficient heat dissipation. Antifreeze is categorized into: 1. Calcium chloride in inorganic compounds; 2. Methanol in organic compounds; 3. Ethanol; 4. Ethylene glycol; 5. Glycerol; 6. Lubricating oil. Precautions for using antifreeze include: 1. Choosing the appropriate antifreeze based on your vehicle's requirements; 2. Using the same brand of antifreeze whenever possible; 3. Avoiding dilution with water.

Why is it bad to sleep in a parked car with the air conditioning on?

The reasons why it is bad to sleep in a parked car with the air conditioning on are: 1. It increases the production and retention of engine carbon deposits; 2. It is not conducive to effective heat dissipation, leading to high engine water temperature; 3. It places a greater load on the engine cooling system; 4. It reduces the service life of the engine; 5. It may cause carbon monoxide poisoning for the occupants. The method to turn on the air conditioning is: 1. Turn the knob in the air conditioning control area to cool or heat; 2. Press the AC button when cooling. The functions of the car air conditioning are: 1. To provide a comfortable environment for passengers and reduce travel fatigue; 2. To create good working conditions for the driver.

What is the appropriate tire pressure for the Boyue?

The normal tire pressure range for the Boyue is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard. The Boyue's tire pressure monitoring system is indirect, utilizing the vehicle's ABS balance control, and only displays low pressure when there is a leak. To check the tire pressure, first prepare a tire pressure gauge, locate the original tire pressure label, press the gauge onto the tire valve to measure and read the value, and remember to replace the valve cap after measurement. Generally, a tire pressure exceeding 2.8 bar is considered too high, while a pressure below 2.0 bar is too low. Hazards of over-inflation: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches the tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of under-inflation: Increased friction coefficient with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; reduces the functionality of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction between the tire and the ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes below, and an exclamation mark inside), there are generally three possible causes: Abnormal tire pressure: Typically, it will alert if the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are needed. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the indicator light to come on. Simply perform a tire pressure reset to resolve this. Damaged tire pressure sensor: The sensor, which monitors tire pressure and is directly installed inside the tire connected to the inflation valve, can be damaged if the tire is impacted while driving, triggering the tire pressure warning light. For sensor damage, the only solution is to replace it with a new part.

Can windshield washer fluid be replaced with water in summer?

Windshield washer fluid can be replaced with water in summer. Windshield washer fluid, short for automotive windshield cleaning fluid, mainly consists of: water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. Windshield washer fluid can be divided into solid and liquid forms based on its state, and it has cleaning and antifreeze properties. The method for adding windshield washer fluid is: 1. Pull the hood switch to open the front hood; 2. Open the washer fluid reservoir cap; 3. While filling, observe the dipstick inside the reservoir and fill up to the marked line. Precautions for using windshield washer fluid include: 1. Regularly check the windshield washer fluid; 2. Use professional windshield washer fluid.
