The reason one side of the low beam does not light up may be due to a blown fuse or a short circuit in the bulb. Here are the relevant details: 1. Detail one: The low beam is designed for close-range illumination, with a large coverage area and a short projection distance, and its focus cannot be adjusted. The projection distance of the low beam is approximately 30-40 meters. 2. Detail two: When driving in areas without streetlights at night, or during dusk when it's darker or at dawn when light is just appearing, the low beams must be turned on. If you encounter heavy fog, snow, or heavy rain that obstructs visibility, the low beams must be turned on even during the day. On some roads where there is lighting but the brightness is insufficient, the low beams should also be turned on.

How much air should be added to a 195/70R15C tire?

195/70R15C tires normally require 2.5 kg of air pressure. If the vehicle is frequently carrying heavy loads, the rear tires should be inflated to 2.7 kg. The standard air pressure for passenger cars is 2.4-2.8 kg/cm². Seasonal factors to consider are as follows: 1. Winter: In colder temperatures, you can slightly increase the standard tire pressure by about 0.2 bar. 2. Summer: In high temperatures, follow the lower limit of the standard tire pressure. If the car is parked outdoors in summer, the pressure can generally be about 0.1 bar lower than the standard to prevent tire blowouts due to heat.

What does the engagement point mean?

Engagement point refers to the position where the clutch is raised just enough to make contact with the power. Lightly rev the throttle and gently lift the clutch; the moment when the car shakes and is about to move forward is the engagement point. Below is a related introduction to the engagement point: 1. Finding the semi-engagement point: Finding the semi-engagement point is essentially finding a critical state. Lifting the foot gradually engages the power, and when the power and resistance are evenly matched, it is the semi-engagement state. The correct posture is to place the ball of the left foot in the center of the clutch pedal, moving the entire foot up and down when pressing. 2. Precautions: During normal driving, the clutch is in a tightly engaged state and should not slip. Therefore, during driving tests (e.g., Subject 3), avoid stepping on the clutch unnecessarily or resting the foot on the clutch. Instead, place the left foot on the ground to the left of the clutch pedal. The vehicle's clutch is only used when starting the car, shifting gears, or braking at low speeds.
