Is Gear Shifting Tested in Subject 3 Driving Exam?

Gear shifting is indeed tested in the Subject 3 driving exam. During the gear shifting segment, when the voice prompt instructs to perform gear shifting, the candidate should adjust the gear to 2nd gear, sequentially shift up to 5th gear (where the speed must exceed 40km/h), and then sequentially shift down to 2nd gear. Gear Up-shifting Operation: After starting with 1st gear, appropriately press the accelerator to increase speed before upshifting. Accelerate to 15-20 km/h before shifting to 2nd gear. During shifting, release the accelerator pedal, depress the clutch pedal, move the gear lever to neutral, then release the clutch pedal. Depress the clutch pedal again, push the gear lever into 2nd gear, and gradually release the clutch while slowly pressing the accelerator to maintain smooth acceleration. The same procedure applies for other upshifts. Gear Down-shifting Operation: When downshifting, release the accelerator pedal and depress the clutch pedal. Push the gear lever to neutral, release the clutch pedal, then lightly press the accelerator to increase engine RPM. Depress the clutch pedal again and push the gear lever into a lower gear. Gradually release the clutch until fully disengaged. Downshifting can skip one gear level but not two. Downshifting can also be used for engine braking during long descents.

Can Autonomous Vehicles Drive on Highways?

Autonomous vehicles can drive on highways. Below is an introduction to the speed regulations for two-lane and three-lane highways: 1. Two-lane highways: This refers to highways with two lanes in the same direction. The speed range for the right lane is 60 to 100 kilometers per hour, while the left lane has a speed range of 100 to 120 kilometers per hour. 2. Three-lane highways: This refers to highways with three lanes in the same direction. The speed range for the far-right lane is 60 to 90 kilometers per hour, the middle lane is 90 to 110 kilometers per hour, and the far-left lane is 110 to 120 kilometers per hour. The left lane is designated as the overtaking lane, hence it has a higher speed limit.

What is the battery model for the Jetour X70 Plus key?

The battery model for the Jetour X70 Plus key is a CR2032 coin cell battery. It can be replaced by yourself, but be careful not to touch the internal circuits and electronic connectors during the replacement process. The key has three function buttons: lock, open the trunk, and start. Additionally, it has the function to lower all four car windows by long-pressing the unlock button. Similarly, if you need to raise all four windows, long-press the lock button. Method to replace the key battery: Turn the car remote key to the back, and you will see the back cover divided into two parts. The side with the key ring has the battery underneath the back cover. There is a gap on the side of the key, both near the key ring and on the side of the key. Insert a flat-head screwdriver into the gap and gently push upward to partially open the back cover. Move the screwdriver along the gap to both sides to gradually widen the gap. You can then fully open the back cover by moving it in the closing direction with your hand to remove it and see the inside of the battery. The protruding clip on one side of the battery can be used to slide the battery out from the other side. Insert the new battery into the car remote key in the opposite direction of removal. Solution for lost car keys: If you lose your car key, the best solution is to replace all the locks on the car, including the door locks and trunk lock. This is undoubtedly the most thorough, safest, and worry-free method, but it is also relatively more expensive.

Is It Normal for the Electronic Parking Brake to Make Noise?

It is normal for the electronic parking brake in a car to make noise. When operating the electronic parking brake, the motor on the rear wheel parking brake will engage, which can produce sound. Releasing the button may also cause noise. However, if the noise is harsh, it is recommended that the car owner immediately inspect the electronic parking brake to prevent malfunctions during use. Relevant details are as follows: 1. The electronic parking brake replaces the mechanical handle, mechanical cable, and mechanical lever. 2. When using the electronic parking brake, it is important to note that if the button is accidentally pressed during high-speed driving, the car's computer will recognize it as a misoperation if it is not held down for a long time. However, if it is pressed for an extended period, an emergency braking signal will be triggered, which can cause significant damage to the car's braking system and compromise safe driving.

Why does the warning light come on after replacing spark plugs?

Poor combustion of air-fuel mixture, sensor issues, maintenance problems, and fuel quality issues. Spark plugs are crucial components in a gasoline engine's ignition system. They introduce high voltage into the combustion chamber and create sparks by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Under high voltage, the air between the spark plug's center electrode and side electrode rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties. This creates a discharge channel between the gap, resulting in a "breakdown" phenomenon. At this point, the gas forms a luminous body known as a "spark." Accompanied by thermal expansion, it also produces a "crack" sound. The temperature of this electrical spark can reach 2000-3000°C, which is sufficient to ignite the air-fuel mixture in the cylinder's combustion chamber.

Is it necessary to slow down when changing lanes in Subject 3?

Whether to slow down when changing lanes in Subject 3 depends on the actual situation. Here are the relevant details: 1. Exam challenges: The main challenges in Subject 3 include: First, speed and gear mismatch. During the exam, you must constantly monitor the speedometer and accelerate or decelerate appropriately before shifting gears. Second, vehicle deviation. Examinees often struggle to judge the vehicle's direction and worry about not maintaining a straight trajectory. 2. Exam content: The Subject 3 exam includes 16 items such as vehicle preparation, light simulation, starting, straight-line driving, passing intersections, left and right turns, etc. Each item is announced via voice command in the exam vehicle, and examinees must respond accordingly. The exam is scored out of 100 points.
