What are the rules for using turn signals when driving in a roundabout?

In a roundabout, the methods for using turn signals are as follows: 1. Changing lanes when entering the roundabout: Generally, vehicles turning left will need to change lanes, and drivers usually choose the inner lane of the roundabout. Since the vehicle needs to move from the outer lane to the inner lane, the left turn signal must be activated to alert vehicles inside the roundabout and those behind, indicating the intention to switch to the inner lane for a left turn and to yield accordingly. 2. Going straight when entering the roundabout: If the vehicle is going straight and does not need to change lanes, there is no need to activate the left turn signal when entering the roundabout. When the vehicle is preparing to exit the roundabout to continue straight, since it needs to cross the right lane inside the roundabout, the right turn signal should be activated to alert other vehicles, and then the vehicle can exit the roundabout. 3. Turning right when entering the roundabout: If the vehicle intends to turn right towards another intersection, it should naturally choose the lane closer to the right side of the roundabout. This situation is similar to the second case, and there is no need to activate the left turn signal. After selecting the corresponding intersection, the driver should activate the right turn signal in advance, confirm it is safe, and then turn right to exit the roundabout.

What does the 'hold' on a car key mean?

The 'hold' on a car key refers to the hold mode. This switch can be seen on the left side of the gear lever. The function of the hold mode is to keep the car in a specific gear range, allowing it to be driven like a manual transmission. For example, if the car is driving in third gear and the hold switch is pressed, the car will continue to drive in third gear. Below is more information about how car keys work: 1. Active working mode: The principle is to control the car door through the vehicle's electronic module and body control module. Simply press the key button to send an unlock or lock command, and after verification by the vehicle's electronic module, the door can be opened or closed. 2. Coil induction working mode: Mainly involves placing an encrypted chip inside the key. During the unlocking process, the vehicle's RF transceiver verifies whether the key matches to determine if the engine can be started. This is primarily used in special situations where the key has no power but the car still needs to start normally. 3. Passive working mode: When entering the sensing area of the key system, as long as the hand touches the door handle, the carried 'key' with identity recognition will receive a low-frequency signal sent by the car. If this signal matches the identity recognition information stored in the 'key,' the 'key' will be awakened.

What to do if a tire is punctured by a nail?

If a car tire is punctured by a nail and there is no air leakage or the leakage is very slow, you can drive at a low speed to the nearest repair shop for inspection. If the air leakage is severe, do not continue driving; instead, replace the spare tire or call for roadside assistance. Solutions for tire air leakage: 1. Severe air leakage: If the tire is losing air rapidly, do not continue driving. Park the vehicle in a safe location immediately and call for assistance or replace it with the spare tire to reach the nearest repair shop. Continuing to drive not only causes irreversible damage to the inner wall of the tire and the rim but also significantly affects the vehicle's handling, especially increasing the risk of skidding on rainy days. 2. Slow air leakage: If the air leakage is slow, you can drive at a low speed to the nearest repair shop. It is advisable to plan your route in advance and locate the nearest auto repair shop to minimize the distance traveled. 3. No air leakage: If the tire is punctured but shows no signs of air leakage, it can still be used. However, it should not be ignored for long, as this can pose significant safety risks. Leaving a nail puncture untreated for an extended period may worsen the damage, leading to a higher risk of a blowout.

Where is the manufacturing date of a car engine located?

Here are the methods to check the manufacturing date of an engine: 1. Check the nameplate in the engine compartment: There is usually an aluminum nameplate inside the engine compartment, which indicates the car's serial number, engine displacement, model, brand, and importantly, the specific manufacturing date. 2. Look for the small nameplate around the door seam: There is a small nameplate around the driver's or passenger's door seam, which clearly states the car's brand, model, manufacturing date, etc. 3. Check the VIN under the windshield: Every car has a VIN under the front windshield, and the 10th digit of the VIN represents the manufacturing date of the car. Each vehicle has a unique VIN.
