An automatic transmission car stalls when braking due to the vehicle's engine auto start-stop function. Automatic transmission cars usually have an "autohold" button that can turn off the auto start-stop feature, or if the brake is not fully depressed, the engine will not automatically stall. Information about the engine auto start-stop is as follows: 1. The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) during driving; when it's time to move forward again, the system automatically restarts the engine. 2. At red lights or in traffic jams, the system minimizes engine idling time to reduce unnecessary fuel consumption.

What does the zigzag line on the highway represent?

The zigzag line on the highway represents longitudinal deceleration markings. Here are some precautions for driving on the highway: 1. Both the driver and front-seat passenger should fasten their seat belts, and the driver should not answer phone calls; 2. Avoid making sharp turns with the steering wheel while driving at high speeds; 3. Do not change lanes arbitrarily while driving. When changing lanes or overtaking the vehicle ahead, the turn signal must be activated in advance; 4. Only adjacent lanes are allowed for overtaking, and the vehicle should return to the driving lane immediately after overtaking. Vehicles must not ride or press on the lane dividing line; 5. Do not reverse, drive in the opposite direction, cross the central divider to make a U-turn or turn, do not test drive or operate a training vehicle, and do not overtake or park on the ramp; 6. Maintain a following distance of more than 100 meters. When the speed is below 100 kilometers per hour, the distance from the vehicle ahead in the same lane can be appropriately shortened, but the minimum distance should not be less than 50 meters.

How Long is Considered as Inventory Car?

Inventory car refers to vehicles that have been in stock for over a year without being sold. There is no clear legal definition for inventory cars, but the term is commonly used in the automotive sales industry. Here are some extended details: 1. Inspection of inventory cars: Inventory cars are often dirty, so extra caution is required when selecting one. After a thorough cleaning, carefully inspect the paint for scratches and dents. If components like wiper blades, engine belts, and tires show no significant signs of aging, the storage conditions are likely acceptable. Checking the battery status can indicate how well the dealer maintains inventory cars. If the battery is periodically charged, the status window should display a green light, indicating normal condition. Also, verify that the VIN code on the certificate matches the engine number and that the stamped numbers are neat and unaltered. 2. Considerations when purchasing a one-year-old inventory car: New cars stored for less than a year can be purchased, often with substantial discounts. However, it's advisable to request the 4S store to replace the original engine oil and check the tire manufacturing date. New tires over two years old may face rubber aging risks, so replacement should also be requested from the 4S store.

What is the appropriate position for seat adjustment?

Seat adjustment to the appropriate position should be determined based on the driver's individual circumstances. Each person's driving habits and height are different, so the seat should be adjusted to a comfortable level. First, depending on the height, there should be at least a fist's distance between the head and the car roof. Secondly, the driver's visibility should be considered, with the line of sight falling on the middle of the windshield. There are three types of car seat adjustments: 1. Height adjustment refers to the driver adjusting the seat height according to their own height and arm length; 2. Front and rear adjustment refers to the distance between the seat and the car pedals. Considering the driver's height, if the distance between the car seat and the pedals is too far, the feet may not reach the pedals, and the accuracy and force when stepping on the pedals will vary greatly. The front and rear position of the seat must be adjusted to a suitable distance; 3. Backrest adjustment refers to the inclination of the seat backrest. The more inclined the seat, the more comfortable it feels, but it should not be overly inclined as it may affect the car's handling. Try to adjust it to a suitable inclination.

What are the functions of the four major chassis systems?

The functions of the four major chassis systems are: 1. Transmission system: Transmits the engine's power to the driving wheels; 2. Running system: Supports and installs various component assemblies of the vehicle, transmitting and bearing various loads from both the vehicle and the ground to ensure normal vehicle operation; 3. Steering system: Ensures the vehicle can travel in the direction selected by the driver; 4. Braking system: Enables the vehicle to decelerate, stop, and reliably remain stationary. The maintenance methods for the chassis include: 1. Regularly check the assembly oil; 2. Replace brake pads and clutch plates in a timely manner; 3. Perform four-wheel alignment; 4. Monitor tire pressure conditions—excessive pressure can lead to tire blowouts, while insufficient pressure increases vehicle resistance and fuel consumption; 5. Keep the vehicle clean by regularly washing the car and cleaning the chassis; 6. Protect metal parts exposed to the air; 7. Clean the original paint layer; 8. Avoid wetting the car's floor mats to prevent chassis rust.

Why does the car sometimes feel underpowered?

The reasons for a car feeling underpowered are as follows: 1. Insufficient fuel supply: The return oil control valve in the pump cover oil passage is not tightly closed, causing unstable engine operation. In severe cases, the engine may stall under slight load and become difficult to start. 2. Fuel leakage in the fuel line: Air entering the system or a clogged fuel filter can obstruct fuel flow, resulting in weak engine performance. 3. Leakage due to damaged sealing copper gasket of the delivery valve: The delivery valve not closing tightly or a broken delivery valve spring can reduce fuel supply, leading to an underpowered engine. 4. Worn plunger pair causing insufficient fuel supply: This is often accompanied by difficulty starting and unstable operation at low throttle. Additionally, sluggish movement of the plunger or roller body, or weak plunger spring tension, can also affect fuel supply and weaken engine performance. 5. Loose plunger adjusting arm: A broken plunger spring or loose adjusting fork on the fuel supply lever can also impact fuel supply, causing the engine to feel underpowered. 6. Fuel injector leakage or clogged nozzle: Poor atomization quality and incomplete combustion after injection can result in weak engine performance, accompanied by knocking sounds and black smoke from the exhaust pipe.
