Where is the forward gear in an automatic transmission car?

In an automatic transmission car, D1, D2, and D3 are all forward gears. 1. D1 is generally used when climbing steep slopes (equivalent to first gear in a manual transmission). 2. D2 is typically used when ascending long slopes. 3. D3 is used on regular roads. 4. On current roads, D1 and D2 are rarely used as the speed is not fast even at high RPM. Below is some information about the D gear: (1) The "D" on the gear shift stands for Drive, which is the forward gear. (2) By placing the gear lever in the "D" position, the driver only needs to control the accelerator pedal to adjust the speed. (3) This gear is undoubtedly the most frequently used one, especially in automatic transmission models. The "D gear for all situations" is a driving mode favored by many drivers.

How to Deal with the Exclamation Mark with a Gear?

An exclamation mark inside a gear is the automatic transmission fault warning light, indicating a fault in the transmission or that the transmission lubricant is below the normal range. It is necessary to replace the transmission oil promptly. The exclamation mark is a common fault warning in cars. Besides the exclamation mark inside a gear, there are four other forms of exclamation marks: an exclamation mark inside a triangle, an exclamation mark inside a circle with parentheses, an exclamation mark with a horizontal line below parentheses, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four situations: General Fault: An exclamation mark inside a triangle. If this symbol lights up, it indicates a fault in the car's general performance or components and functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Brake System Fault: An exclamation mark inside a circle with parentheses. This represents a warning for the brake system, mainly indicating a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Tire Pressure Anomaly: An exclamation mark with a horizontal line below parentheses. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, signaling a fault in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.

What does DPF light mean?

There are two situations when the DPF light is on. 1. The automatic catalytic cleaning of the diesel particulate filter will cause the DPF light to turn on. 2. A malfunction in the diesel particulate filter causes the DPF light to turn on. Classification of car dashboard indicator lights: 1. Red indicator lights: Red lights are generally danger warning lights. If these red indicators are lit and ignored, they can either have a significant impact on driving safety or cause considerable damage to the vehicle itself. 2. Yellow indicator lights: Yellow lights are malfunction indicator lights. When yellow lights on the dashboard are lit, they inform the driver that a certain system function of the vehicle has been lost. 3. Green indicator lights: Green lights are status indicator lights, showing the current working state of the vehicle. For example, the power mode indicator of an automatic transmission or the HINLO for body height adjustment does not warn the driver but indicates the current state of the vehicle.

Will a speed exceeding 10% but less than 20% result in points deduction and fines?

Exceeding the speed limit by 10% but less than 20% will result in a 3-point deduction and a fine, with the fine amount varying depending on the circumstances. Below is an introduction to the penalties for speeding and situations where speeding does not incur points or fines. Penalties for speeding: Driving medium-sized or larger passenger or cargo vehicles, school buses, or hazardous material transport vehicles on highways or urban expressways at speeds exceeding the limit by 20% or more, or driving such vehicles on other roads at speeds exceeding the limit by 50% or more, as well as driving other motor vehicles at speeds exceeding the limit by 50% or more, will result in a 12-point deduction. Driving medium-sized or larger passenger or cargo vehicles, school buses, or hazardous material transport vehicles on highways or urban expressways at speeds exceeding the limit by less than 20% will result in a 6-point deduction. Driving medium-sized or larger passenger or cargo vehicles, school buses, or hazardous material transport vehicles on roads other than highways or urban expressways, or driving other motor vehicles at speeds exceeding the limit by 20% but less than 50%, will result in a 6-point deduction. Driving medium-sized or larger passenger or cargo vehicles or hazardous material transport vehicles on roads other than highways or urban expressways, or driving other motor vehicles at speeds exceeding the limit by less than 20%, will result in a 3-point deduction. Driving a motor vehicle on a highway at a speed below the minimum speed limit will result in a 3-point deduction. Situations where speeding does not incur points or fines: On roads with speed limits below 60 km/h, speeding by less than 50%. For ordinary vehicles, if the speed exceeds the limit by less than 10%, a warning is issued without penalty. For example, on a highway with a speed limit of 120 km/h, driving at 128 km/h, which is less than 7% over the limit, will not result in points or fines.

What Oil to Use in All Seasons?

For all seasons, oil grades such as 5W40, 5W30, 5W20, 0W40, 0W30, 0W20, etc., can be used. The classification of oil and the reasons for the oil light to come on are as follows: Oil Classification: Oil grades are represented by a combination of two letters. The 'S' series represents oil for gasoline engines, with specifications ranging from SA to SN in alphabetical order, skipping SI, with each increment representing a higher grade. The 'C' series represents oil for diesel engines. If both 'S' and 'C' letters are present, it indicates that the oil is suitable for both gasoline and diesel engines. Reasons for the Oil Light to Come On: High engine temperature can thin the oil, causing it to leak excessively through the clearances and leading to a drop in oil pressure. Insufficient oil quantity reduces the oil pump's output or prevents it from pumping oil due to air intake, resulting in decreased oil pressure. Improper clearance between the crankshaft and the main or connecting rod bearings—too tight increases oil pressure, while too loose decreases it, among other reasons.

How Much Transmission Fluid Should Be Added?

Generally, about 4 liters of fluid are needed. The types of transmissions and precautions for transmission break-in are as follows: Types of transmissions: AT transmission, which is a hydraulic automatic transmission. CVT transmission, which is a mechanical continuously variable automatic transmission. AMT transmission, which is an electronically controlled mechanical automatic transmission. Dual-clutch transmission, which has two sets of clutches inside the transmission. Manual transmission. Precautions for transmission break-in: Shift gears promptly while driving, especially avoiding lugging the engine. Lugging increases the engine load and causes impact on the engine, suspension, and chassis. Some cars equipped with intelligent transmissions will have the transmission learn the driver's habits during the first 500km of the break-in period. The transmission's computer will calculate an optimal working mode to improve the car's comfort and fuel efficiency. Therefore, it is best not to frequently change drivers during the first 500km of the break-in period to allow the intelligent transmission to adapt to the learning process.
