You cannot turn on the air conditioning without starting the car. The car's air conditioning compressor relies on the engine's operation to function, and the heat for the warm air is generated by the engine warming up. If the car is only powered on but not started, turning on the air conditioning will not produce cooling or heating effects. Functions of the car air conditioning: 1. Achieve cooling effects through the continuous cycle of refrigerant; 2. Remove dust, odors, smoke, and toxic gases from the car's interior air, making the air fresher, and humidify the air to increase relative humidity. Maintenance methods for car air conditioning: 1. Do not set the temperature too low; 2. Control the direction of the air vents; 3. Avoid prolonged use; 4. Appropriately use high fan speed; 5. Turn off the air conditioning when driving at low speeds.

Does the Lavida's handbrake brake the front wheels or the rear wheels?

The handbrake of the Lavida brakes the rear wheels. The handbrake, also known as an auxiliary brake, can achieve the parking brake function by pulling it up when the vehicle is stationary. Principle of the handbrake: The handbrake uses a steel cable connected to the rear brake shoes to brake the vehicle. As a mechanical auxiliary brake, the handbrake actually only brakes the rear wheels. However, long-term use of the handbrake may cause the steel cable to deform, reducing the braking effect. Principle of the foot brake: The foot brake generally adopts a dual-circuit hydraulic braking system. When using the foot brake, the braking system evenly distributes the force from the master cylinder to all four wheels. The foot brake provides better braking performance on all four wheels and has a higher safety factor.

Does the Geely Emgrand have cruise control?

Some models of the Geely Emgrand, such as the Emgrand GSe and Emgrand GS, are equipped with a cruise control system, which allows the car to maintain a constant speed within a certain range. Functions of cruise control: After cruise control is activated, it automatically maintains the speed set by the driver and can also adjust the speed, pause cruise control, etc., via the control switch. During long-distance driving, cruise control not only reduces driver fatigue but also minimizes unnecessary speed changes, thereby saving fuel. Precautions for using cruise control: While using cruise control, drivers must wear seat belts and use this function within the specified speed range. Additionally, cruise control should be used with caution or avoided altogether on winding roads, in heavy traffic, or when the road is wet due to rain.

Can the Chery Ant be charged on rainy days?

Chery Ant can be charged on rainy days, but it is necessary to ensure that the charging port is not submerged in water. Chery Ant range: Chery New Energy Vehicle product Ant features an all-aluminum body structure, which results in an ultra-lightweight body that significantly extends the vehicle's range, achieving an NEDC range of 510km and a maximum range of up to 600km. Such an extended range can fully meet the needs of consumers. Moreover, it charges quickly, faster than most new energy vehicles. Chery Ant appearance: The vehicle's body dimensions are 4630mm in length, 1910mm in width, and 1655mm in height, with a wheelbase of 2830mm.

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.
