How many car keys come with a new car?

Typically, a car comes with two keys: one spare key and one for regular use. What to do if you lose your car key: 1. If you are certain the key was not stolen and was lost in an uncommon parking area, you can go to a 4S shop or auto parts market to get a replacement key. The service station will require the vehicle and the owner's ID documents. Depending on the car model, the service station may also need the 17-digit anti-theft code for key configuration. Once this code is obtained, the service station can make a metal key for the owner. Additionally, they will modify the car's computer parameters to deactivate the lost key, rendering it unable to start the vehicle, though it may still physically open the door. 2. For 100% security, you can visit a 4S shop or auto parts market service station to replace all the locks. The number of locks that need to be replaced varies depending on the car model.

What are the full English names of the gears in an automatic transmission car?

Gear P stands for Parking, gear R stands for Reverse, gear N stands for Nogear, gear D stands for Drive, gear L stands for Low, and gear S stands for Sport. Gear P means parking or stopping, commonly known as the parking gear. When engaged on flat ground, the vehicle will brake without the need to press the brake pedal. Gear R means reverse, so R is the reverse gear. Of course, you must ensure the car is completely stopped before shifting into R to avoid damaging the transmission. Gear N means that when this gear is engaged, power is not transmitted to the drive wheels. This gear can help save fuel, but this only applies to manual transmission vehicles. However, it is not recommended to use this gear when going downhill, as it can easily cause unnecessary damage. Gear D is called the Drive or Forward gear. It is used when moving forward. Gear L is the Low gear. When going downhill or on long slopes, engaging this gear limits the car to the lowest gear automatically, preventing the need for prolonged braking, which can overheat the brake pads and pose a danger. Gear S stands for Sport mode. When engaged, gears can shift freely, but the shift timing is delayed, keeping the engine at high RPM for a period to increase the car's power. However, this mode will result in higher fuel consumption.

What lights to use when going straight through an intersection?

When going straight through an intersection, learners should use low beam headlights. If there is a voice prompt to pass through an intersection without traffic signal control, it is necessary to alternately use high and low beam headlights twice. The following are scenarios for the use of other lights: Turn signal usage scenarios: Turn signals should be activated 100 to 50 meters in advance when turning, changing lanes, overtaking, making a U-turn, or pulling over to the side of the road. The left turn signal should be activated in advance when turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn. The right turn signal should be activated in advance when turning right, changing lanes to the right, returning to the original lane after overtaking, or pulling over to the side of the road. When overtaking, the left turn signal should be activated in advance, and high and low beam headlights should be alternated or the horn should be sounded. Low beam headlight usage scenarios: On roads without central separation facilities or center lines, low beam headlights should be switched on when meeting oncoming vehicles at night at a distance of more than 150 meters from the opposite direction. Low beam headlights should also be used when meeting non-motorized vehicles on narrow roads or narrow bridges. High and low beam headlight usage scenarios: When passing through sharp curves, slopes, arched bridges, crosswalks, or intersections without traffic signal control at night, high and low beam headlights should be alternately used.

What Causes an Automatic Transmission Car to Fail to Shift Gears?

Automatic transmission cars may fail to shift gears due to reasons such as the gear lock being engaged, the P-lock mechanism being stuck and unable to reset, a damaged shift solenoid valve, or a malfunction in the control computer. Gear lock engaged: If the gear lock is engaged or stuck, the gear lever will inevitably fail to shift. In this case, you can use the key to unlock the gear lock. If this doesn't work, check the brake. When pressing the brake, observe whether the brake light turns on. If the brake light does not illuminate, the brake switch may be damaged. The car's computer cannot detect whether the brake is pressed, thus preventing gear shifting. The brake switch should be replaced promptly. P-lock mechanism stuck and unable to reset: The transmission P-lock mechanism consists of a lock gear, a lock pin, and a set of operating components. When shifting the gear lever to P, the cable drives the connecting ball pin, causing the working pin to slide and engage the lock pin pawl with the parking gear, thereby achieving parking lock. If the P-lock mechanism is stuck and cannot reset, it needs to be manually reset. Damaged shift solenoid valve: If the shift solenoid valve is damaged, it cannot execute shift commands. In this case, a repair shop should be consulted to replace the solenoid valve. Control computer malfunction: In this scenario, it is necessary to contact a 4S shop or repair center for professional maintenance.

Does the third-generation EA888 consume engine oil?

The third-generation EA888 engine no longer has the issue of excessive oil consumption. While some oil consumption is normal, excessive consumption leads to the problem of burning oil. The following factors can exacerbate oil consumption and lead to burning oil: 1. Carbon deposits in the combustion chamber can cause the piston rings to stick, leading to poor sealing. 2. Sludge formation in the lubrication system can block the oil return holes of the oil control rings, reducing their oil-scraping efficiency. 3. Wear between the pistons and cylinder walls. 4. Corrosion or aging of the valve seals, resulting in loss of sealing performance. 5. Modern vehicles are equipped with a crankcase ventilation system (PCV valve), and if it malfunctions, it can also increase oil consumption.
