In a car, 'reg' refers to the cruise control function. Below is a detailed introduction to the cruise control system: 1. Function: The cruise control system, abbreviated as CCS, automatically maintains the vehicle's speed once the driver reaches the desired speed, eliminating the need to press the accelerator pedal, thus allowing the vehicle to travel at a fixed speed. Using this device during long highway drives reduces driver fatigue by eliminating the need to control the accelerator pedal and minimizes unnecessary speed variations, which can save fuel. 2. Usage conditions: The cruise control system is not suitable for all situations. In principle, it should be used on highways or fully enclosed roads. This is because on non-enclosed roads, complex road conditions can compromise traffic safety.

Where should temporary license plates be affixed?

Temporary license plates should be affixed to the lower left or lower right corner of the front windshield inside the vehicle, with another one affixed to the lower left corner of the rear windshield inside the vehicle. For passenger vehicles that have not yet been registered, if they need to be driven temporarily on the road, they must carry two temporary license plates, which must be affixed in the specified positions. For other types of vehicles, due to installation limitations, only one temporary license plate is required, but it must still be affixed to the lower left or lower right corner of the front windshield inside the vehicle. According to regulations, motor vehicle license plates should be hung in the designated positions at the front and rear of the vehicle, kept clear and intact. Heavy and medium-duty trucks, their trailers, and tractors should have enlarged license numbers painted on the body or the rear of the cargo compartment, with the characters upright and clearly visible.

What to Do If the Car Is Not Driven for a Period of Time?

Methods for dealing with a car that hasn't been driven for a while: 1. Warm up the car every week and drive for about 15 minutes to ensure lubrication of moving parts and the formation of protective oil films, while also replenishing the battery's charge appropriately; 2. Check the battery every month to see if there are signs of power loss. If signs of power loss appear, the engine can be used to charge the battery appropriately; 3. If you're going on a long trip, you can entrust the car to relatives or friends to take care of it in this manner. Hazards of not driving the car for a long time: 1. If the car is not driven, it will experience severe power loss after 3 months and won't be able to start; 2. If the car is parked for too long, the engine will lose the protection of the lubricating oil film, leading to oxidation and corrosion, which can reduce engine power and shorten its lifespan.
