An automatic car can shift from D to S while driving, and switching between S and D can be done at any time, but it should not be done when the engine speed is high. Introduction to automatic transmission gears: 1. P gear is the parking gear, used for long-term parking of the vehicle; 2. R gear is the reverse gear, engaged when the vehicle needs to move backward; 3. N gear is the neutral gear, engaged when the vehicle is parked for a short time without turning off the engine; 4. D gear is the drive gear, when the gear lever is in D, the vehicle will automatically shift gears based on throttle opening and speed data; 5. S gear is the sport mode, making the vehicle drive more sporty; 6. M gear refers to the manual mode, when the gear lever is in M, shifting is done manually by the driver; 7. L gear is the low gear.

Absolutely, I do this all the time while driving, and it feels particularly exhilarating. Switching to S mode makes the vehicle more responsive, with higher RPMs and earlier shift points, giving a sense of abundant power without hesitation during overtaking or acceleration. It's perfectly safe to switch directly while driving—no hidden risks. From my experience, just a gentle push of the gear lever above 60 km/h, and the system immediately adjusts its logic without harming the transmission. Just remember not to overuse it, or fuel consumption will skyrocket, and the engine can overheat. S mode is especially useful on downhill slopes, providing engine braking to reduce the burden on the brakes. Combining this, I always adjust the gear flexibly based on different road conditions, making driving more fun and safer.

Yes, I occasionally shift to S mode while driving an automatic transmission car, such as when overtaking or climbing hills. It mainly enhances power response, keeping the vehicle in a higher RPM range for more sensitive acceleration, and the transition is smooth without worrying about damage. As a safe driver, I recommend using it only when necessary, as D mode is more fuel-efficient and comfortable for normal cruising. An additional consideration is that the electronic control system is designed with buffering mechanisms, preventing knocking even if accidentally shifted. If driving long distances with family, S mode can briefly boost performance to avoid dangerous overtaking, but it's best used sparingly to minimize engine wear risks.

How often should the coolant be replaced for a Haval H2?

Haval H2 engine coolant should be checked every 6 months and replaced every 24 months. Here are more details about the coolant: 1. Most family cars require coolant replacement every two years or 40,000 kilometers, but the specific replacement interval depends on the vehicle's usage and whether the coolant level is below the minimum mark (the normal coolant level should be between MIN and MAX; if it's too low, it should be topped up promptly to avoid affecting the engine's cooling efficiency). 2. Long-term failure to replace the coolant can lead to deterioration in its quality, reducing its anti-corrosion properties. This can damage components like the radiator and pipes and affect the boiling and freezing points, compromising the coolant's effectiveness. Do not wait until the coolant turns black before replacing it—blackened coolant indicates severe deterioration and significant scale buildup, which may have already damaged the pipes. During each maintenance check, use a freezing-point tester to measure the coolant's freezing point. If the freezing point is too high, it means the coolant has deteriorated and needs replacement. 3. Generally, coolant should be replaced every two years or around 60,000 kilometers. Coolant prevents freezing when the vehicle is not running, as it resides in the engine block. If the liquid turns into a solid, it expands, which can crack the engine block. Additionally, after the vehicle starts, the coolant helps cool the engine to prevent overheating and potential damage. It also plays a role in preventing rust and excessive scale buildup, which can clog the pipes.

Where is the OBD interface located in the Touran?

The OBD interface of the Volkswagen Touran is located behind the plastic cover under the steering wheel. OBD is the abbreviation for On-Board Diagnostics, which means the vehicle's automatic diagnostic system in Chinese. Information about the vehicle's automatic diagnostic system is as follows: 1. The vehicle's automatic diagnostic system can monitor important parts of the car in real-time and will issue an alarm promptly when a fault occurs. 2. The parts monitored by OBD include the oxygen sensor, fuel system, engine, emission control system, catalytic converter, EGR, particulate filter, etc.

What documents should I bring for the first car maintenance?

Items required for the first maintenance include: driver's license; vehicle registration certificate; maintenance manual; warranty manual; owner's ID card; vehicle's driving license; vehicle purchase invoice, to be taken to the designated first maintenance facility for the service. Important note: make an appointment with the 4S shop in advance. The first maintenance refers to the initial service after a new car has been driven, with the specific time varying by vehicle, usually after driving 1,000 to 3,000 kilometers. It is essential to attend the first maintenance on time, neither in advance nor delayed. The completion of the first maintenance marks the end of the car's break-in period, allowing it to be driven under standard loads and normal speeds as required by the vehicle. The timing of the first maintenance is calculated from the date of vehicle pickup. There are two indicator values for the first maintenance: mileage and time. Whichever comes first serves as the standard. The first maintenance items include: oil change, oil filter replacement, air filter cleaning, checking various fluid levels for normalcy, inspecting the generator belt and wiper blades for damage, checking tire pressure for normalcy, and inspecting tires for damage or bulges. Estimated time required: approximately 2 hours to complete all tasks. The most crucial aspect of the first maintenance for a new car is the replacement of engine oil and the oil filter. When changing the oil, the oil filter must also be replaced. The selection of oil must refer to the "Vehicle Usage and Maintenance Manual," as different vehicle models specify different oil grades. Maintenance precautions: Do not wash the interior of the car body with water: Many people clean their cars during holidays, washing the body with water and wiping it with a cloth. It is important to note that the interior of the car body should not be directly washed with water. If the floor mats are dirty, use a vacuum cleaner or take them out to brush and clean with detergent, dry them, and then put them back. There are many vent holes under the rubber mats on the floor of the driver's compartment. Water entering these areas will not dry naturally but will flow through the holes to parts like the gearbox, causing erosion and corrosion. The best practice is to clean with a vacuum cleaner and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is low, it is recommended to drain the existing antifreeze and add the same brand from the beginning. Different brands of antifreeze have significantly different chemical properties. Various functional additives may corrode others. Different brands of antifreeze use different additives, so they should not be mixed to avoid unnecessary issues. Do not lubricate tire bolts and nuts: When bolts on a moving car rust, they are often oiled to function properly again. Some people apply lubricant to bolts and nuts to prevent rust, but this poses a risk to safe driving. At high speeds, bolts and nuts can easily loosen or even fall off, leading to driving failures. Do not press the accelerator when starting an EFI (Electronic Fuel Injection) car: The starter of an EFI car differs from that of a conventional car. Its fuel injection control device can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring a smooth start.

What material are car bumpers made of?

Car bumpers are typically made of plastic, although some older or special-purpose vehicles may have metal bumpers. The material used for bumpers varies depending on the vehicle's function and driving environment. Car bumpers not only enhance the vehicle's appearance but also provide a safer driving environment for the driver. Reasons for using plastic bumpers in cars: 1. Weight reduction - Plastic bumpers are lighter than metal ones, helping achieve vehicle weight reduction goals, which in turn helps drivers save fuel and reduce emissions. 2. Pedestrian safety - In the event of a traffic accident, plastic bumpers offer better protection for pedestrians due to their excellent impact resistance, reducing potential injuries caused by the bumper.
