BMW 5 Series steering gear excessive friction causes: Low-quality lubricating oil leads to poor lubrication effect. Mechanical steering system: The mechanical steering system uses the driver's physical strength as the steering energy source, consisting of steering control mechanism, steering gear and steering transmission mechanism. The series of components from steering wheel to steering transmission shaft belong to the steering control mechanism, while the series of parts from steering knuckle arm to steering trapezoid belong to the steering transmission mechanism. Power steering system: The power steering system uses both driver's physical strength and engine power as steering energy sources. Normally, the driver only provides a small portion of the required steering energy, while most energy is provided by the engine through power steering devices. When the power steering device fails, the driver should be able to independently undertake the vehicle steering task. Therefore, the power steering system is formed by adding a set of power steering devices to the mechanical steering system.

Do hybrid vehicles need regular charging?

There are two types of hybrid electric vehicles. Standard hybrid models can charge the battery while driving. Plug-in hybrid models consume battery power and generally do not require charging. For non-plug-in hybrid vehicles, the hybrid system utilizes part of the engine's power to generate electricity and store it in the battery when high engine output isn't needed. Plug-in hybrid electric vehicles represent a new generation of hybrid technology. More details are as follows: 1. Taking Toyota's Leiling Dual Hybrid as an example, during coasting phases the drive motor functions as a generator, converting kinetic energy into electrical energy to charge the vehicle's battery. 2. The Leiling's battery has a range of 40 kilometers, but since it has charging capability, the battery doesn't need charging as long as it shows normal status, eliminating the need for frequent charging. 3. For plug-in hybrids like the 2018 Changan Ford Mondeo Plug-in Hybrid, since the drive motor lacks battery charging capability, the battery power is constantly in a consumption-only state. Therefore, charging is typically required before each trip.

How to Use the Windshield Wiper in Subject Three?

The method to use the windshield wiper in Subject Three is: by pushing the wiper control lever, you can control the wiper's operation modes (intermittent, off, auto, and high/low speed). When in the auto mode, you can also adjust the sensitivity on the lever to control the wiper's frequency. Of course, it's essential to consider the current rainy conditions—higher frequency isn't always better. If the rain is light but the wiper is set to the highest speed, it may obstruct the driving view. More details are as follows: 1. Learn to use the washer switch, as there may occasionally be difficult-to-remove impurities (like bird droppings or resin) on the windshield. 2. To use it, simply pull the wiper lever toward yourself, and the washer fluid and wiper will work simultaneously. 3. Some models use a physical button, usually located on the outermost part of the wiper control handle—just press it to activate.

What Causes All the Warning Lights in a Car to Illuminate?

There are several reasons why all the warning lights in a car may illuminate: 1. CAN bus failure in the ECU, or poor contact at the ECU's CAN interface. 2. Excessive dirt and carbon deposits, causing abnormal air flow and preventing accurate control of the normal air intake, leading to unstable gas content and poor engine performance. 3. Low fuel pressure combined with poor constant pressure performance results in low system atomization levels, making the car difficult to start. 4. If all dashboard lights remain illuminated after the vehicle starts, it could be due to dashboard wiring faults, engine failure, transmission failure, brake system failure, coolant temperature issues, etc.

What Insurance Policies Are Needed When Buying a Car?

First and foremost, compulsory traffic insurance is a must, as it is mandated by the state. Additionally, vehicle damage insurance, third-party liability insurance, and no-deductible insurance are essential. Below are the details of these auto insurance policies: 1. Vehicle Damage Insurance: The most widely used type of auto insurance, it covers the loss of your own vehicle in the event of a traffic accident, such as falling objects or unexpected incidents. It is recommended to purchase coverage equal to the value of your vehicle. 2. Third-Party Liability Insurance: Often referred to as 'third-party insurance,' it covers the legal liability of the insured driver for bodily injury or property damage to a third party caused by the insured vehicle. Similar to compulsory traffic insurance, it can be seen as a supplement to the coverage limits of compulsory insurance. If you collide with a luxury car, the coverage provided by compulsory insurance alone may be insufficient, and the resulting losses could be substantial. 3. No-Deductible Insurance: After an accident, the insurance company may impose a deductible based on the policyholder's liability, with a maximum deductible of 20% for full liability and a minimum of 5% for partial liability. No-deductible insurance is an additional policy that eliminates these deductibles and can only be purchased as an add-on to a primary insurance policy.

What should be noted for the first car maintenance?

Here are the precautions regarding the first car maintenance: 1. The first maintenance time of the car is calculated based on the pickup date. 2. There are two indicators for the first maintenance time: mileage and time. Whichever comes first, maintenance must be performed. Exceeding either will affect the warranty. It is worth mentioning that according to relevant regulations, if the first maintenance date is exceeded, it will be regarded as automatically waiving the rights of the first maintenance. If the first maintenance is not performed, future quality issues of the car will not be guaranteed. 3. The first maintenance time and maintenance cycle of the car are different. Some car maintenance cycles are only 2000 kilometers, while others are as long as 8000 kilometers. The engine and the new car have a break-in period. The first car maintenance includes the following: 1. Replace engine oil, oil filter, clean air filter, check whether the generator belt and wiper blades are damaged, check whether the levels of various fluids are normal, check whether the tire pressure is normal, and whether the tires have uneven wear, bulges, or damage. 2. Check the car chassis: including whether the brake pads, brake discs, connecting rods, ball joints, and CV joints are scratched. 3. Check all the switches and lights in the car to see if they are working properly.
