How to Turn on the Car Ventilation?

To ventilate the car, locate the air recirculation switch and use the external circulation mode. The specific steps are: 1. Find the air recirculation switch, rotate it to the external circulation position, and adjust the temperature control knob to the middle position between hot and cold; 2. Push up the air vent button to open it, then adjust the direction of the air flow; 3. Rotate the fan speed control button to set the desired airflow intensity. The purpose of external circulation is to connect the air inside and outside the car, thereby replenishing fresh air. While the vehicle is moving, airflow automatically enters the car due to wind pressure. When the car is stationary, outside air flows through the air duct into the blower, which then blows it into the car. The air inside the car is then expelled through the exhaust vents at the rear of the cabin, achieving a circulation effect.

Ventilating your car is actually quite simple. I remember when I first started driving, I always felt the car was stuffy. Later, a friend taught me that car ventilation is usually handled by the air conditioning system. After getting in the car and starting the engine, look for the air conditioning control area near the dashboard. There, you'll find a fan icon or knob—turning it will activate the fan to blow air. If there's an AUTO button, pressing it will automatically turn on the ventilation mode, adjusting airflow based on the interior temperature. Automatic air conditioning is quite smart—it intelligently switches between recirculation and fresh air modes. The fresh air mode brings in outside air, while recirculation maintains a stable interior temperature. Pay attention to the scenario when operating it: use fresh air mode on highways in summer for faster cooling, but switch to recirculation in city traffic to avoid exhaust fumes. I also learned that regularly replacing the cabin air filter is important to prevent dirty air. If fogging occurs, switch to defog mode—safety first.

What is car FM?

Car FM refers to the frequency modulation band in the radio function. Its working principle is: modulating the audio signal onto the frequency of a high-frequency carrier wave, transmitting it into the air, the FM radio receives the radio signal through the antenna, separates the audio signal through tuning, intermediate frequency amplification, and frequency discrimination circuits, and then amplifies the low frequency to output sound through the speaker. The buttons in the car are divided into: 1. Fuel tank opening button: remotely opens the fuel tank cap inside the car; 2. ESP switch: used to turn the vehicle's ESP on and off; 3. Central lock button: the control button for the vehicle's central door lock; 4. Headlight cleaning button: controls the automatic cleaning function of the headlights; 5. Rear sunshade button: controls the opening and closing of the electric rear sunshade inside the car.

What is the tire model of the Peugeot 3008?

The tire model of the Peugeot 3008 is 225/50r17. The functions of the tires are: 1. Transmit driving force, braking force, and steering force to achieve vehicle operation; 2. Support vehicle load; 3. Reduce and absorb vibrations and impact forces during driving, avoiding severe vibrations that may damage vehicle components. Taking the 2019 Peugeot 3008 as an example, it belongs to the compact SUV category, with body dimensions of: length 4435mm, width 1840mm, height 1652mm, wheelbase of 2613mm, fuel tank capacity of 60l, and curb weight of 1540kg. The 2019 Peugeot 3008 features a front McPherson independent suspension and a rear torsion beam non-independent suspension. It is equipped with a 1.6L turbocharged engine, delivering a maximum horsepower of 167ps, maximum power of 123kw, and maximum torque of 245nm, paired with a 6-speed automatic transmission.

What Does the Car Grille Mean?

The car front grille is a mesh-like component with grid patterns located at the front of the vehicle. Positioned between the front bumper and the front crossbeam of the body, the front grille requires an engine hood lock avoidance hole on its upper surface area to accommodate the placement of the engine hood lock. Beyond aesthetics, the primary functions of the front grille are air intake and reducing air resistance. The front grille significantly impacts the engine compartment's resistance, which accounts for about 10% of the total drag. An active grille shutter helps minimize resistance within the engine compartment. An active grille is an adjustable intake grille that can open or close based on vehicle speed and cabin temperature. After the vehicle starts, the active grille adjusts its opening degree according to the engine temperature, achieving quicker warm-up effects and allowing the engine to reach optimal operating conditions faster. During high-speed driving, keeping the grille fully open increases aerodynamic drag and fuel consumption. Timely closure of the grille reduces the drag coefficient, thereby enhancing vehicle stability and fuel efficiency.

Should You Slow Down and Yield When Driving Through an Unsignalized Intersection?

Driving through an unsignalized intersection requires slowing down and yielding. The specific guidelines are as follows: 1. Look, slow down, then proceed: When driving through an intersection without traffic signals, you should slow down within 50-100 meters of the intersection. Upon reaching the intersection, carefully observe the traffic conditions on both sides, slow down or stop to look around, following the principle of "look, slow down, then proceed." Vehicles going straight have the right of way. If there is a stop sign at the intersection, come to a complete stop, observe the main road conditions, and proceed only after confirming safety. 2. Passing through unsignalized intersections at night: When driving through an unsignalized intersection at night, you should alternate between high and low beams. When passing through sharp curves, slopes, arched bridges, crosswalks, or unsignalized intersections at night, vehicles must alternate their headlights between high and low beams as a signal. At intersections, switching between high and low beams is necessary to alert vehicles on either side.

Is Full Coverage Insurance Mandatory in the First Year of Car Purchase?

Full coverage insurance is not mandatory for a new car in the first year, and you can purchase insurance according to your needs. Typically, new cars are often insured with full coverage because the combination of a new car and an inexperienced driver increases the likelihood of accidents. However, when renewing insurance in the second year, car owners can choose the coverage items based on their own needs. Usually, when registering a new car, in addition to paying various taxes, it is also necessary to purchase compulsory traffic insurance, which is a mandatory requirement by the state. The concept of full coverage insurance typically includes the following types of coverage: Third-party liability insurance: This refers to the third-party liability insurance clause, where the insurance company compensates for the other party's losses if you collide with them while driving. Vehicle damage insurance: This is the vehicle loss insurance clause, where the insurance company compensates for the loss of your own vehicle in case of natural disasters or collisions. Passenger liability insurance: This is the motor vehicle passenger liability insurance clause, where the insurance company compensates for the losses of the driver and passengers in case of injuries during an accident.

Can points be deducted 15 days before the driver's license expires?

It is best not to have points deducted on the day the driver's license expires. Below is relevant information about driver's license point deductions: 1. Point reset time: The cumulative penalty point cycle for road traffic safety violations (i.e., the point cycle) is 12 months, with a maximum of 12 points. It is calculated from the date the motor vehicle driver's license is initially issued and continues to cycle accordingly. The point reset time for the driver's license is the issuance date on the license. The system automatically resets the points on the issuance date each year, with one year constituting a point cycle. 2. Point cycle: If the initial issuance date of the driver's license is May 3, 2010, then the point cycle is from 00:00 on May 3, 2010, to 24:00 on May 3, 2011. 3. Automatic reset in the next cycle: If the penalty points recorded during a point cycle do not reach 12 points, the point system will automatically reset the recorded points (after fines are paid) at the start of the next point cycle.
