What is the size of the steering wheel cover for Haval H2s?

Haval H2s steering wheel cover has an approximate diameter of 37. Comfort steering mode: Suitable for general driving habits. Sport steering mode: Reduces power steering assistance and increases steering feedback, recommended for use in situations such as high-speed driving or heavy rain. Light steering mode: Increases power steering assistance, making steering easier, suitable for driving in congested urban traffic environments. Haval H2 has three driving modes: Economy mode, Normal mode, and Snow mode. In Normal mode, the transmission starts shifting up around 2000rpm, maintaining higher RPM ranges to keep the power readily available. Of course, drivers can also lightly lift the accelerator pedal to signal the transmission to upshift. Additionally, during rapid acceleration, the transmission's shift logic is quite satisfactory, though the slightly sluggish shift speed somewhat hinders the overall process.

Why Does New Engine Oil Have a Bad Smell?

New engine oil having a bad smell may indicate the use of counterfeit or inferior products. Precautions for adding engine oil are as follows: 1. Choose engine oil based on the requirements of the engine. Do not use high-grade oil in lower-grade engines or low-grade oil in high-grade engines; select oil that matches the engine. 2. Multi-grade oil should be preferred. Multi-grade oil offers advantages such as fuel economy, long service life, and high efficiency, providing better protection for the engine. 3. The oil level should be slightly below the mark on the dipstick and not overfilled. Excessive oil not only increases the rotational resistance of the crankshaft but also reduces the engine's output power. Moreover, excess oil can enter the combustion chamber and participate in combustion, leading to oil burning, blue smoke emissions, and increased fuel consumption. 4. Select oil with different viscosities based on the engine's operating condition. If the engine is in good condition and the seasonal temperature is low, use oil with lower viscosity. If the engine is severely worn and the seasonal temperature is high, opt for higher viscosity oil. 5. Always drain the existing oil completely and clean the lubrication system thoroughly before adding new oil to avoid mixing different types.

Why Do New Cars Have Rusty Screws?

New cars having rusty screws may indicate they are inventory vehicles that have been stored for an extended period, leading to screw rust. Solutions for rusty screws are as follows: 1. Tap the screw with a hammer or wrench. When a screw is rusted, avoid forcing it with a wrench as this will only tighten it further. Instead, use a wrench to grip the screw and strike the wrench handle with a hammer. A few firm strikes will loosen the rusted parts inside the screw, making it much easier to turn. 2. Apply cola to the rusted screw. Rust primarily consists of iron oxide, and cola contains carbonic acid, which reacts chemically with the rust, making it easy to remove and allowing the screw to turn freely. 3. If the screw is severely corroded, heating it with a flame is an option. Use an oxyacetylene torch to thoroughly heat the screw, then apply a drop of oil to the heated screw. The principle of thermal expansion and contraction will create more space between the screw and the nut. 4. Directly spray rust remover onto the rusted screw. Once the rust remover penetrates the screw, it can be easily unscrewed.

Can the New Santana Start Without Pressing the Brake?

Manual transmission Santana can start without pressing the brake, while the automatic transmission New Santana requires pressing the brake. When starting the car, pressing the clutch facilitates ignition, and pressing the brake prevents the car from rolling when in neutral. New Santana Models: The 2021 New Santana is available in four versions: Automatic Comfort Edition, Automatic Trend Edition, Manual Comfort Edition, and Manual Trend Edition. Scenarios Requiring Brake Pressing for Ignition: Automatic transmission models and keyless start models require pressing the brake to start. The design principle of these models mandates pressing the brake for ignition; otherwise, the car cannot start. Scenarios Not Requiring Brake Pressing for Ignition: Manual transmission models do not require pressing the brake to start. The purpose of pressing the brake is to prevent the car from rolling or sliding during the starting process. Not pressing the brake will not affect the car's ignition.

Why does a new car show an engine fault?

There are several possible reasons why a new car shows an engine fault: 1. Sensor issues. Sensors include those for coolant temperature, crankshaft position, air flow, intake temperature, oxygen, etc. When these sensors are damaged, have poor connections, or signal interruptions, the car's ECU cannot accurately obtain engine data, which can trigger the engine fault light. 2. Maintenance issues. Vehicles have specific maintenance schedules. If the owner fails to follow the schedule and has poor driving habits, it can increase the burden on the engine. 3. Fuel quality issues. If the owner does not use the required fuel type, prolonged use can cause engine wear. 4. Poor combustion of the air-fuel mixture. Faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can all lead to poor combustion. 5. Air intake issues. A dirty air filter that is not cleaned regularly can affect the car's air intake, potentially leading to blockages over time. 6. Turbocharger issues. Problems with the intake boost pipes or turbocharger can also trigger the engine fault light. 7. Exhaust system issues. This includes the rear oxygen sensor, catalytic converter, exhaust camshaft, and bearings. 8. Anti-theft system. A malfunctioning anti-theft system can prevent the engine from operating normally and may also trigger the engine fault light.
