Why is the Honda Elysion reverse radar not beeping?

Why does the car air conditioner not cool when running but cools when parked?

If the car air conditioner does not cool when running but cools when parked, the reasons are as follows: 1. Lack of Freon: The lower engine speed causes the compressor speed to be relatively lower, and the lack of Freon means the instantaneous pressure boost does not reach the standard state, resulting in low high pressure and suboptimal cooling performance. 2. Compressor pressure leakage: This directly leads to severely low pressure during idle. 3. Air conditioner cooling fan not working: When parked, due to insufficient cooling and the absence of wind speed during driving to lower the temperature, the pressure becomes excessively high, causing the high-pressure sensor to force the compressor to stop working, thus resulting in no cool air.

What Causes the Screeching Metal Friction Sound from the Front Wheels?

The screeching metal friction sound from the front wheels can be caused by foreign objects between the brake disc and brake pads, a damaged brake separation pump, or excessive wear of the brake pads. Details are as follows: Foreign objects between the brake disc and brake pads: Check if there are any wire-like objects entangled around the wheel or the nearby drive half-shaft. Damaged brake separation pump: If the vehicle is not regularly maintained, it can lead to wear of the brake caliper's moving pins, detachment of spring plates, and other issues. Poor caliper resetting can cause prolonged friction of the disc, resulting in abnormal noise. Additionally, check if the brake disc has grooves, as localized friction can also cause noise. Excessive wear of the brake pads: Inaccurate four-wheel alignment can cause significant tire wear during long-distance driving, leading to uneven tire wear and abnormal noise.

What causes the air conditioning to stop cooling after a vehicle goes through water?

The reasons why the air conditioning stops cooling after a vehicle goes through water are as follows: 1. Air entering the vehicle's air conditioning system: This can cause excessive pressure in the refrigeration pipes or form ice blockages, leading to poor refrigerant circulation and resulting in no cooling. 2. Loose drive belt of the air conditioning compressor: During compressor operation, this can cause slipping, reducing transmission efficiency, slowing down the compressor speed, and causing compressor wear or valve leakage, which decreases the delivery of compressed refrigerant and directly reduces the cooling capacity of the air conditioning system or stops cooling altogether. 3. Low power supply or voltage: The electromagnetic clutch of the compressor will have reduced suction, and oil contamination between the clutch pressure plate and the pulley may occur, leading to a 'slipping' condition similar to a loose drive belt.

What is the width of a car?

Generally, a sedan is about 4.8 meters in length and 1.8 meters in width. Below are detailed introductions about it: 1. Introduction 1: Vehicle dimensions refer to the regulatory limits on the total height, total width, and total length of a car. 2. Introduction 2: The width of a car refers to the distance between two planes parallel to the longitudinal symmetry plane of the vehicle and touching the outermost rigid fixed protrusions on both sides of the vehicle (excluding rearview mirrors, side marker lights, position lights, turn indicators, etc.). 3. Introduction 3: The length of a car refers to the distance between two vertical planes perpendicular to the longitudinal symmetry plane of the vehicle and touching the outermost front and rear protrusions of the vehicle.

What is the normal range of tire pressure in kPa?

The standard tire pressure is 240-250 kPa, and the reinforced tire pressure is 280-290 kPa, which is the normal tire pressure range. However, the specific normal tire pressure for a car should be based on the manufacturer's recommended value, which can generally be found in the vehicle's user manual, the label near the driver's door (B-pillar), the drawer next to the driver's seat, or the small door on the fuel tank cap. The manufacturer's recommended value will provide detailed information on the specific tire pressure for the tires. Tire pressure standards also depend on the type of tire and the vehicle model. Different vehicle models have varying weights, heights, and tire sizes, and thus require different tire pressures. Additionally, the tire pressure for cold tires and hot tires is different, with hot tires having a pressure about 20 kPa higher than cold tires. The manufacturer's recommended value refers to the cold tire pressure, which is typically around 230-250 kPa when the vehicle is cold, but the exact value should be based on the specific tire pressure indicated for each vehicle. Small cars: Normal tire pressure is 210-230 kPa, 220-240 kPa when the seats and trunk are fully loaded, and 220-230 kPa when the speed exceeds 140 km/h. Compact cars: Normal tire pressure is 220-240 kPa, 230-250 kPa when the seats and trunk are fully loaded, and 230-250 kPa when the speed exceeds 140 km/h. Mid-size cars: Normal tire pressure is 230-250 kPa, 240-260 kPa when the seats and trunk are fully loaded, and 240-260 kPa when the speed exceeds 140 km/h. Large mid-size cars: Normal tire pressure is 250-270 kPa, 270-290 kPa when the seats and trunk are fully loaded, and 270-290 kPa when the speed exceeds 140 km/h. Large cars: Normal tire pressure is 260-300 kPa, 280-310 kPa when the seats and trunk are fully loaded, and 280-310 kPa when the speed exceeds 140 km/h. Furthermore, tire pressure is significantly affected by seasonal factors. In summer, high temperatures can cause tires to heat up during driving, and high tire pressure can lead to blowouts, so the pressure should be slightly lower. In winter, tire pressure should be slightly higher than in summer due to thermal contraction and expansion, so a tire pressure of 250-280 kPa is generally more suitable for winter. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; causing steering wheel vibration and deviation, reducing driving comfort; accelerating wear on the central tread of the tire, shortening tire life; increasing vehicle vibration, indirectly affecting the lifespan of other components; overstretching the tire cords, reducing tire elasticity, and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; causing heavy steering and deviation, which are unsafe for driving; increasing movement in various parts of the tire, leading to excessive rolling and abnormal heating; reducing the functionality of the cords and rubber, causing delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; significantly increasing friction between the tire and the ground, rapidly raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a blowout.

Does the Audi Q3 have independent suspension?

Audi Q3 has independent suspension. Independent suspension location: An independent suspension system means that the wheels on each side are individually suspended under the frame or body through an elastic suspension system. Most modern cars use independent suspension systems, which can be further divided into different structural types such as transverse arm, longitudinal arm, multi-link, strut, and MacPherson suspension systems. Advantages of independent suspension: Light weight, reducing the impact on the body and improving wheel traction; softer springs with lower stiffness can be used to enhance ride comfort; it allows the engine to be positioned lower, lowering the car's center of gravity and improving driving stability; the left and right wheels can move independently, reducing body tilt and vibration.
