New energy vehicles' three electric systems refer to the battery, motor, and electronic control system. Below is an introduction to these three components: Battery: The battery here does not refer to the one that powers vehicle lighting, air conditioning, etc., but rather the high-voltage battery responsible for providing the power source. The performance of a pure electric vehicle's battery directly determines its driving range. Motor: The motor system is the high-voltage motor that provides torque to the vehicle, supplying it with power. A vehicle can be equipped with one, two, or four motors, which are currently divided into two types: AC asynchronous motors and permanent magnet synchronous motors. Electronic Control System: Its main function is to collect various signals such as the accelerator, brake pedal, and steering wheel, and issue corresponding instructions based on the received information. The electronic control system needs to control the speed and direction of the drive motor, as well as manage energy recovery and other tasks.

What is the first maintenance mileage for the Kia Stonic?

First maintenance refers to the initial service for a new car. The first maintenance for the Kia Stonic is typically performed at around 7,500 kilometers. Below is a related introduction to the first maintenance of a car: Introduction to the items included in the first maintenance: The first maintenance only requires changing the engine oil, oil filter, and air filter. The first maintenance can usually be completed in about an hour. First maintenance is very important for a car, so it's essential to perform it on time—neither delaying nor advancing it. First maintenance refers to the initial service after a new car has been driven, and the exact timing varies by vehicle, usually performed after driving 1,000 to 3,000 kilometers. Cars should undergo first maintenance on schedule, neither earlier nor later. Completing the first maintenance indicates that the vehicle's break-in period has ended, and it can then be driven according to the standard load and normal speed specified by the manufacturer. The first maintenance time is calculated from the date of vehicle delivery. There are two indicators for first maintenance: mileage and time, whichever comes first. Exceeding either of these may affect the warranty. Precautions for the first maintenance: Before the first maintenance, fully understand whether your car has any other faults or issues, and note them down. When registering for the first maintenance, inform the 4S shop about these items that need to be checked. Before maintenance, review the user manual to understand the general content of this service and any items that may require out-of-pocket expenses. A few days before the maintenance, call the 4S shop to schedule an appointment. Prepare the user manual (must bring), driver's license, digital camera, or a camera phone for the maintenance.

What is the normal tire pressure for the Mercedes V260?

The recommended tire pressure range for the Mercedes V260 is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and decreased by 0.1 bar in summer. This data complies with the international GBT2978-2008 standard. The tire pressure monitoring data for the Mercedes V260 is displayed on the central screen of the instrument panel. Generally, the tire pressure monitoring can be operated via the steering wheel buttons. Generally speaking, a tire pressure exceeding 2.8 bar is considered too high, while a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates uneven wear of 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 underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement of various tire parts, causing abnormal heat due to excessive rolling; weakens the function 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 at the bottom, and an exclamation mark inside), it is generally due to one of the following three reasons: Abnormal tire pressure: Usually triggers an alarm when below 1.8 bar or above 3.0 bar. In this case, the tires need to be checked and the pressure adjusted. Tire pressure monitoring not reset: After inflating the tires, the system was not reset in time, causing it to display the previous data, which triggers the indicator light. Simply reset the tire pressure monitoring system. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If the sensor is damaged during driving (e.g., by hitting a curb), the tire pressure warning light will illuminate. In this case, the only solution is to replace the sensor with a new one.

What is the sequence of B2 Subject 2?

Pole shifting, parallel parking, ramp stop, single-plank bridge, curve driving, right-angle turn, pressing cakes, passing through a width-limited gate, driving on undulating roads, narrow road U-turn, simulating continuous sharp bends on mountain roads, simulating rainy/foggy weather, simulating slippery roads, simulating tunnel driving, simulating highway driving, simulating emergency handling, etc. These are the 16 items of the B2 driver's license Subject 2 test. Below is the detailed sequence of the B2 Subject 2 test items: Pole Test: Reverse from the starting point into the B garage and stop properly, then move the vehicle two times forward and two times backward to shift to the A garage and stop properly. Then drive forward out of the B garage to the control line, reverse into the A garage and stop properly, and then drive forward back to the starting point. The vehicle must not stop during the process, and the total time must not exceed 8 minutes. Parallel Parking: After the vehicle is parked properly on the right side in front of the garage, reverse into the garage in one go without stopping. The wheels must not touch or press the lane boundary lines or the garage boundary lines. Single-Plank Bridge: During the test, the vehicle must not stop, and the wheels must not fall off the bridge. Narrow Road U-Turn: Drive the vehicle to the U-turn section and park on the right side. Complete the U-turn within no more than three forward and two backward movements. The test time must not exceed 5 minutes. Right-Angle Turn: Drive the vehicle along the specified route, making a right-angle turn from left to right or right to left in one go without stopping. The wheels must not touch or press the lane boundary lines. Slope Stop and Start: Control the vehicle to stop accurately and start smoothly without rolling backward. The start time must not exceed 30 seconds. Simulated Highway Driving: After driving to the entrance ramp, turn on the left turn signal, look back to the left to observe oncoming traffic, and after confirming safety, accelerate into the driving lane to reach the minimum speed limit and drive normally, then turn off the turn signal. When changing lanes, turn on the turn signal for the lane you intend to enter, observe the traffic situation, and change lanes after confirming safety. When exiting the highway, adjust the speed and lane in advance according to the exit warning signs. Simulated Emergency Handling: During normal driving, one of the following emergency situations will be randomly selected and simulated using voice or lights: If an obstacle suddenly appears ahead, brake immediately, stop quickly, and turn on the hazard warning lights after stopping. In case of a flat tire or other vehicle malfunction while driving on the highway, reduce speed appropriately, observe the following traffic, park the vehicle steadily in the emergency lane, turn on the hazard warning lights, prompt passengers to move outside the guardrail, place the warning sign correctly, and the driver should move outside the guardrail to simulate calling for help. Curve Driving (commonly known as S-curve): The test requires the vehicle to drive on an S-shaped road of specified width without pressing the road edge lines, with smooth steering control. This assesses the driver's ability to maneuver the vehicle through curves and control its trajectory, aiming to develop skills in steering and wheel path control. Simulated Tunnel Driving: Before entering the tunnel, observe the road traffic signs at the tunnel entrance and operate accordingly. When approaching the tunnel, reduce speed, turn on the headlights, and sound the horn. When exiting the tunnel, sound the horn again and turn off the headlights. Do not sound the horn in no-horn zones. Simulated Rainy/Foggy Weather Driving: Drive at reduced speed. In rainy conditions, adjust the wiper speed according to the rainfall. In foggy conditions, turn on the fog lights, position lights, headlights, and hazard warning lights. Simulated Slippery Road Driving: Before entering the slippery road, reduce speed. After entering, use a low gear to drive steadily and control the vehicle direction smoothly. Simulated Continuous Sharp Bends on Mountain Roads: Reduce speed before reaching the bend, drive on the right side, sound the horn before entering the bend, and avoid occupying the opposite lane while driving. Passing Through a Width-Limited Gate: Drive through the three gates at a speed of no less than 10 km/h without touching the hanging rods.
