What Causes Severe Shaking and Jerking When Starting in First Gear?

What is the difference before and after the first maintenance?

Generally, after the first maintenance, the fuel consumption of the vehicle may change, and the acceleration during driving may become more responsive. During the first maintenance, the car will be inspected, ensuring better driving safety. When scheduling the first maintenance, owners need to make an appointment in advance to save time and avoid waiting in line. Below is more information about the first maintenance: 1. When changing the engine oil during the first maintenance, the old oil containing debris must be drained from the engine. The first maintenance is usually free. During daily driving, it's important to keep track of the car's performance and provide feedback to the technician during the first maintenance to avoid potential issues. 2. After the first maintenance, regular maintenance is typically required every 5,000 kilometers. Even if the car is not used frequently, timely maintenance is necessary to prevent component failures that could affect driving safety. 3. During the first oil change, many 4S shops drain the old oil from the engine using the oil pan drain bolt. However, this method may not completely remove all the old oil. A specialized oil extractor can be used to suction out the remaining oil. 4. During the first maintenance, various components of the car should be inspected, including fluid levels and tire pressure. The car's lighting system should also be checked to ensure proper functionality.

How to adjust the rear seats of the Buick GL8?

The side of the rear seats of the Buick GL8 has buttons for adjustment. Press the buttons to adjust the front and rear positions—pressing the front part moves the seat forward, while pressing the rear part moves it backward. The armrests of the rear seats can be adjusted by pulling them manually. Here is more information about the Buick GL8: 1. The new Buick GL8 features a dual-armrest design, offering an aviation-like seating experience. The third row of the Buick GL8 consists of fully fixed seats, which can only be folded in the more common 4/6 split configuration. The folding method involves pulling the rings located at the bottom left and right of the rear seats to fold them separately, thereby increasing trunk space. Proportional folding allows the rear seat backrests to be divided proportionally, enabling any side to be folded down as needed to meet the requirements for increased trunk storage space and rear passenger capacity. 2. The driver's seat of the Buick GL8 is an electric seat. The electric seat control system not only allows for adjustments in seat sliding and tilting but also enables adjustments in front vertical, rear vertical, headrest, and lumbar cushion positions. Simply pulling or pressing the buttons can achieve electric-driven seat movement forward and backward, as well as backrest adjustments.

What are the dimensions of the Explorer?

Ford Explorer's length, width and height are 5075mm, 2004mm and 1778mm respectively, with a wheelbase of 3025mm. Below are the detailed specifications of Ford Explorer: 1. Vehicle Positioning: Ford Explorer is a mid-to-large size SUV. 2. Interior: The 12.8-inch vertical central control screen is equipped with SYNC+2.0 intelligent information entertainment system, which supports GPS navigation, voice recognition control, multimedia entertainment and other functions. The L2-level Ford Co-Pilot360 intelligent driving assistance system is also standard across all models. 3. Power: The entire series adopts a high-specification 2.3T+10AT powertrain combination, with the engine delivering a maximum power of 276Ps and a maximum torque of 425Nm. The rear-wheel-drive model can accelerate from 0 to 100km/h in just 7.6 seconds. Except for the entry-level model, all other models are equipped with a four-wheel-drive system, with a fuel consumption of around 12L per 100 kilometers.

What to Do About Car Battery Leakage?

Solutions for car battery leakage are as follows: 1. Visual Inspection: It is necessary to inspect the exterior of the battery to check if the casing is cracked. If there are small holes or overflow on the leaking surface, plastic welding can be used to patch them up. After patching, the concentration of the battery fluid can be measured with a hydrometer, and an appropriate amount of sulfuric acid and purified water can be added as needed. If it's due to evaporation, simply top it up with more fluid. 2. Internal Inspection: If the first step shows no issues, remove the panel and check for any signs of leakage around the safety valve. If there are none, proceed to the next step. If there are, the safety valve needs to be repaired or replaced. 3. Leakage Check: If the first two steps show no abnormalities, a pressure test is required. This involves pressurizing the battery with air underwater to check for bubbles. If bubbles appear, it indicates a leakage. If no bubbles are present, the battery is functioning normally.

How Often Should CVT Transmission Fluid Be Changed?

CVT transmission fluid generally needs to be changed every two years or every 40,000 kilometers. However, this may vary depending on the vehicle model, as different models have different requirements. The primary function of transmission fluid is to keep the shifting system clean and to lubricate the transmission components, thereby extending their lifespan. Below is more detailed information: 1. Due to differences in transmission design, transmissions are categorized into manual and automatic (which further includes CVT, AMT, etc.). Each transmission type has unique technical requirements. Even the same transmission model, when installed in different vehicles, may differ in torque, weight, speed, and structure. Therefore, manufacturers specify their own dedicated transmission fluids. 2. Automatic transmission fluid (ATF) is specifically designed for automatic transmissions. Early automatic transmissions did not use dedicated fluid but instead relied on engine oil. Due to significant differences in operating conditions and technical requirements, using engine oil as transmission fluid was quickly phased out. Modern automatic transmission fluid serves as both the hydraulic fluid for the torque converter and the lubricant for the planetary gear structure, as well as the hydraulic fluid for the shifting mechanism. Under normal driving conditions, ATF should be changed every 120,000 kilometers, while under severe driving conditions, it should be changed every 60,000 kilometers.

What are the reasons for feeling lack of power when stepping on the accelerator?

Specific reasons for feeling that the car lacks power and accelerates slowly when stepping on the accelerator are as follows: 1. Clutch slipping: The main cause of clutch slipping is insufficient friction on the clutch friction plate; shifting gears prematurely or disengaging before the clutch is fully engaged; driving for extended periods with the clutch partially engaged or coasting with the clutch depressed; shifting or disengaging gears improperly, and applying excessive throttle when the gear is not fully engaged or disengaged, leading to abnormal wear of the clutch plate. 2. Engine issues: The source of power is fuel combustion, and the engine is responsible for supplying fuel and converting chemical energy into mechanical energy. Therefore, when the car lacks power and accelerates slowly, the engine system should be a key focus for inspection. 3. Engine oil system: The importance of engine oil is self-evident—it ensures sufficient lubrication, reduces resonance, and enhances the smooth operation of the engine. If the engine oil is insufficient for a long time, mild cases may result in insufficient power and increased fuel consumption; severe cases may lead to piston knocking, causing mechanical damage to related components. Additionally, a faulty fuel pump or a clogged fuel filter can also reduce engine power. 4. Engine intake system: Besides fuel, the engine also requires air. If components like the air filter or throttle valve are clogged or malfunctioning, leading to insufficient air intake, the car may experience sluggish acceleration, lack of power, and a jerky sensation.
