It is recommended to drive at 15 km/h in 1st gear, 25 km/h in 2nd gear, 35 km/h in 3rd gear, 55 km/h in 4th gear, and 65 km/h in 5th gear. Car transmission: The car transmission is a gearbox containing many gears. The driving gear (connected to the engine via the clutch) receives power from the engine to drive the driven gear (connected to the wheels via the main reducer and drive shaft), thereby rotating the wheels. Each gear has a pair of driving and driven gears, and engaging a specific gear means connecting that particular pair of gears to transmit power. Introduction to gears: P gear is the parking gear, used for long-term parking; R gear is the reverse gear, engaged when the vehicle needs to move backward; N gear is the neutral gear, used when the vehicle is parked for a short time without turning off the engine; D gear is the drive gear, where the transmission automatically shifts gears based on throttle opening and speed data when the gear lever is placed in D.

What are the techniques for beginners to straighten the steering wheel?

Turn the steering wheel 90 degrees left and right on the spot to feel the weight of the steering wheel. Align the steering wheel to make 90 degrees light, and rotate one circle to make 90 degrees heavy. After parking, just move slightly forward or backward to determine whether the steering wheel is aligned, and you can make timely adjustments during the movement. When parking, if possible, stick your head out of the window to see if the tires are complete, which makes it easier to align the steering wheel while driving. Whether it's turning the steering wheel half a circle or turning it, there's no need to turn it several times at the right moment; just move the handle logo back to the top.

What to Do When the Tire Pressure Warning Light Comes On in Snowy Weather?

When the tire pressure warning light comes on in snowy weather, you can turn on the ignition switch, press and hold the tire pressure monitoring reset button until you hear a "beep" sound, then release it. At this point, the tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off. Hazards of Low Tire Pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes the steering wheel to feel heavy and may lead to drifting, which are factors detrimental to driving safety; Increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; Reduces the functionality of the cord and rubber, leading to delamination or cord breakage, excessive friction with the rim causing damage to the bead area, and abnormal wear; The friction between the tire and the ground multiplies, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving under these conditions may lead to a tire blowout; Increases tire body deformation, making the tire sidewalls prone to cracking, while generating flexing movements that lead to excessive heat, accelerating rubber aging, fatigue of the cord fabric layer, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulders.

What to Do When Keyless Start Key is Left in the Car?

Cars usually come with two standard keys. If the key is locked in the car, you can use the spare key. This method results in zero loss. Start with the seal strip on the front left door. Insert a sturdy wire along the door seal strip and use the wire to press the unlock button on the central lock. Use a mobile phone for remote unlocking. This function is generally achieved by connecting the phone to a cloud system, which then transmits a signal to the car to unlock it. Find a nearby locksmith company. Unlocking this way will not cause any damage to the car's components, and there's no need to replace the car lock. Both 4S shops and repair shops can provide special unlocking services, but the car must first be towed to the repair shop.

In the longitudinal driving assistance, the setting for automatic lane change when turning on the turn signal is a necessary driving setting. The shortcut button on the steering wheel, the button at the lower right corner on the left side, is the switch for the autonomous driving function. Press it to activate autonomous driving with one click.
