When driving an automatic transmission car up a steep slope, use the L gear, which is the low-speed gear. The method for starting an automatic transmission car on an uphill is: 1. Press the brake while pulling up the handbrake; 2. Shift the gear to L or S gear and gradually apply the throttle; 3. When the car's forward power is held back by the handbrake, slowly release the handbrake, and the vehicle will start climbing the slope smoothly. An automatic transmission means that the driver does not need to manually shift gears; the vehicle will automatically select the appropriate gear based on the driving speed and traffic conditions. The gears of an automatic transmission car are: 1. P gear is the parking gear; 2. R gear is the reverse gear; 3. N gear is the neutral gear; 4. D gear is the drive gear; 5. S gear is the sport mode.

My personal experience driving up steep slopes is that it's best to switch to manual mode or a lower gear. When driving an automatic transmission car, I often find that the D gear lacks sufficient power on steep slopes, with the engine roaring but the speed not increasing. In such cases, shifting into L or S gear can lock the transmission in a lower gear, avoiding frequent gear changes. This results in more stable engine RPM and smoother power output. It's advisable to downshift before climbing the slope; never wait until the car starts rolling back to change gears. Last week, on a winding mountain road with continuous sharp turns and steep slopes, using manual mode fixed in 2nd gear made it much easier, with no shaking or struggling from the car body. Similarly, when descending long slopes, it's essential to engage a lower gear to use the engine's braking force to control speed, preventing the brake pads from overheating and failing.

How to Use ETC After Successful Activation?

Usage method after successful ETC activation: 1. You need to recharge the ETC card and attach the small device to the front windshield; 2. When entering the ETC lane at highway toll stations, maintain a speed of approximately 20 kilometers per hour, and the toll will be automatically deducted. ETC is an electronic toll collection system that doesn't require stopping. The ETC dedicated lane is designed for vehicles equipped with ETC onboard units, utilizing electronic toll collection methods. The ETC non-stop toll system achieves the purpose of paying bridge and road tolls without stopping by establishing microwave-dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations, using computer networking technology for backend settlement processing with banks.

What does driving on the shoulder mean?

Driving on the shoulder refers to a vehicle traveling on the far-right lane of the road, which is the edge section adjacent to the roadside. On both regular roads and highways, driving on the shoulder is prohibited due to its high risk, especially on highways where the far-right lane is designated as an emergency lane. The emergency lane is not permitted for regular vehicle traffic. Under normal circumstances, the shoulder is not allowed for driving. However, in emergencies (including vehicle breakdowns), vehicles may briefly stop on the shoulder. Special vehicles such as police cars, ambulances, and tow trucks performing official duties have the right of way, and other vehicles may only pass under police direction. Therefore, the shoulder can also be referred to as an emergency stopping lane or emergency driving lane. The emergency lane is primarily designated for situations involving traffic accidents where police cars, ambulances, or fire trucks need immediate access to the scene for rescue operations. During normal driving, it is illegal to occupy the emergency lane, and prolonged driving or stopping in this lane is strictly prohibited. Emergency lanes are typically marked on both sides of urban ring roads, expressways, and highways.

What is the reason why Wuling Zhiguang cannot accelerate when the engine is hot?

Check the fuel pressure. Check whether the intake manifold (including the air filter) is unobstructed. The following is a related introduction to Wuling Motors: 1. Introduction: Wuling is the registered trademark and brand of Liuzhou Wuling Automobile Co., Ltd. This logo has been fully authorized for use by SAIC-GM-Wuling. 2. Appearance: Wuling Hongguang adopts the currently very popular double U front face design and a three-dimensional vertical waterfall-style chrome-plated air intake grille, which not only makes the front of the car look more fashionable and dynamic but also inherits some characteristics of the General Motors series. The eye-catching eagle-eye crystal diamond headlights and feather-shaped crystal diamond front fog lights further enhance the vehicle's sense of grade. The two powerful lines on the engine hood give a strong sense of power visually.

What Causes Engine Oil to Leak into the Radiator?

Causes of engine oil in the car radiator: 1. Blown head gasket: After the head gasket is damaged, the oil passage and coolant passage become connected. Since the oil pressure is higher than the coolant pressure, the oil enters the coolant passage and then the radiator. Observe air bubbles escaping from the surface of the radiator coolant. After stopping the engine, the coolant will flow into the oil passage and then into the oil pan. 2. Cracked cylinder liner: Due to the high fuel pressure in the cylinder, oil and diesel are "squeezed" into the coolant through cracks in the cylinder liner under high pressure. Observe the surface of the coolant for intense movement of air bubbles. 3. Faulty oil cooler: During assembly or manufacturing of the oil cooler, cracks in the cooling tubes, poor welding, or freezing and cracking of the cooling tubes due to not draining the coolant properly in winter can cause oil to enter the coolant. If you observe the surface of the radiator coolant, it is generally calm.
