Manual transmission cruise control typically requires the vehicle to be in the highest gear (5th or 6th gear) before it can be activated. When the driver reaches the desired speed, they can engage the cruise control, and the vehicle will maintain that speed. The cruise control can be deactivated by pressing the brake or the cruise control off button. Additional information is as follows: 1. Meaning of Cruise Control System: The cruise control system (CRUISE-CONTROL-SYSTEM), abbreviated as CCS, is also known as a speed control device, speed control system, or autonomous driving system. 2. Function: Once the driver sets the desired speed, the system automatically maintains that speed without the need to press the accelerator pedal, allowing the vehicle to travel at a constant speed. Using this system reduces driver fatigue during long highway drives by eliminating the need to control the accelerator pedal, while also minimizing unnecessary speed variations and saving fuel.

After driving for so many years, I love using the highest gear when cruising on the highway, like 6th gear, keeping the engine RPM steady around 2000. It's fuel-efficient and quiet, making the drive super smooth. Of course, you can't rigidly stick to the gear—it depends on speed. High gears work best between 80 to 120 km/h. If climbing a hill or accelerating, temporarily downshift. Remember, too high RPM (like over 3000) wastes fuel, while too low RPM can lug the engine and cause damage. Checking gear matching during regular maintenance can extend transmission life. Getting used to listening to engine sound changes is a good habit—don’t just rely on the dashboard.

What are the body dimensions of the Beijing BW007?

Beijing BW007 has a length, width, and height of 4595mm/1828mm/1830mm, which are official data. The length of the Beijing BW007 refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding parts at the front and rear of the vehicle. The width refers to the distance between two parallel planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle. The height refers to the distance between the highest point of the vehicle and the supporting plane of the vehicle. The turbocharged engine of the Beijing BW007 has a maximum power of 140kw and a maximum torque of 250 Nm. This engine reaches its maximum power at 5500 rpm and its maximum torque between 2400-4800 rpm. It is equipped with multi-point fuel injection technology and uses an aluminum alloy cylinder head and cast iron cylinder block. This engine is paired with a manual transmission (MT). The state has relevant regulations regarding vehicle dimensions. According to the national standard "GB1589-89," the total width of a vehicle does not include rearview mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. This means that, according to national standards, the significance of vehicle width data is to ensure enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5m to meet the usage requirements of public roads.

What are the indicators on the dashboard?

The most common indicators on the dashboard include: door warning, handbrake warning, seatbelt warning, engine self-check, lubricant condition check, ABS system check, airbag check, battery warning, and fuel level warning. Common warning indicators: The car dashboard is a device that reflects the working status of various vehicle systems. Common indicators include fuel indicator, washer fluid indicator, electronic throttle indicator, front/rear fog light indicator, and warning lights. Under the dashboard cover, various indicator or warning lights are installed, such as coolant level warning light, fuel level indicator, washer fluid level indicator, charging indicator, high/low beam indicator, transmission gear indicator, anti-lock braking system (ABS) indicator, traction control indicator, airbag (SRS) warning light, etc. Common gauges: Dashboards vary between different vehicles. However, conventional gauges in most cars typically include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, and charging gauge. The speedometer actually consists of two gauges: one showing speed and the other displaying mileage.

How does the 4S shop compensate for the new car's malfunction indicator light being on?

Below are two scenarios regarding how a 4S shop compensates for a new car's malfunction indicator light being on: 1. The maintenance personnel use a computer to read the car's fault codes, inspect and repair the corresponding faulty parts, and the 4S shop will repair the faulty components. 2. If the new car frequently has issues with the malfunction indicator light being on, and the owner requests a car replacement or refund, it depends on whether the owner's specific situation meets the conditions. According to the national new three-guarantee law, consumers are entitled to conditions for car replacement or refund. There are several reasons why the malfunction indicator light of a newly purchased car may be on: 1. Every time the vehicle is started by ignition, all malfunction indicator lights on the dashboard will light up. This is a normal phenomenon, indicating that the car's electronic system is performing a self-check on the vehicle components. After a while, if the components are in normal condition, the malfunction indicator lights will turn off. 2. If there is a genuine fault issue with the new car's components, the light will remain on.

Is the compulsory insurance label no longer required to be displayed?

If electronic insurance policies have been implemented in your region, vehicles are no longer required to display the compulsory traffic insurance label. In regions where electronic insurance policies have not been implemented, vehicles must still display the compulsory insurance label. Below are the key points to note: 1. The removal of the label requirement does not mean the purchase of compulsory insurance is optional. During traffic police inspections or annual vehicle inspections, the electronic insurance policy must be presented for verification. For vehicles without compulsory insurance or with expired policies, traffic authorities have the right to impound the vehicle, impose a fine of twice the amount of the compulsory insurance premium, and require the completion of necessary procedures. 2. For the use or production of 'fake' insurance labels, public security traffic police departments will confiscate them, impound the vehicle, and impose a fine ranging from 200 to 2,000 yuan. If the act constitutes a crime, criminal liability will be pursued according to the law. 3. In regions where the compulsory insurance label is still required, failure to display it as required may result in the vehicle being impounded by traffic authorities until the owner provides the corresponding documents, labels, or completes the necessary procedures. Additionally, a warning or a fine ranging from 20 to 200 yuan may be imposed, and 1 point will be deducted from the driver's license.

How Often Should a Truck's Air Filter Be Replaced?

Truck air filters generally need to be replaced every 10,000 kilometers or every six months. Below are the consequences of a dirty air filter: 1. Increased Fuel Consumption: If the air filter is severely dirty, it will restrict airflow, leading to sluggish acceleration. Insufficient oxygen can also cause incomplete combustion of the air-fuel mixture, reducing engine power and requiring more fuel supply, which increases fuel consumption. In severe cases, the exhaust may emit thick, foul-smelling smoke. 2. Impact on Health: After prolonged use, the air conditioning system accumulates impurities, dust, and bacteria. These contaminants are blown directly into the cabin, deteriorating the air quality inside the vehicle and affecting the health of the driver and passengers.
