The plus symbol represents upshifting, while the minus symbol represents downshifting. Principles of car gears: 1. N stands for neutral. Selecting the N button disengages the transmission and disconnects the driven wheel of the transmission. At this point, the car will move based on its own weight, momentum, and inertia, which is equivalent to turning off the engine. The car cannot rely on the engine to operate and move, so remember not to use neutral when going uphill. 3. D stands for drive. Its principle is to engage all possible forward movement gear ratios through the transmission, with these ratios generally ranging between 3-9. 4. Overdrive (OD). The principle of overdrive is to allow the automatic transmission to overload. If the automatic transmission is turned off, the gears will automatically downshift under hard acceleration.

How many types of red are there in automotive red paint?

Red paint is divided into two types: Passion Red and Bordeaux Red. Passion Red resembles the color of fire, while Bordeaux Red is a shade similar to red wine. The color of the paint does not significantly affect the price, which generally follows the order: standard paint -- metallic paint -- matte paint -- color-shifting paint. Most paints available in the market are standard or metallic, categorized into domestic and imported brands. Domestic paints tend to fade over time. Additional information: Buyers typically choose paint based on the car model rather than simply by color. For example, silver metallic paint used by Mercedes-Benz is not the same as others. The choice of paint grade depends on specific requirements, and nowadays, paint mixing is usually free, with paint sold by weight.

Is It Advisable to Buy a Flood-Damaged Car with Water Reaching the Seats?

Flood-damaged cars are not recommended for purchase due to significant potential issues in the long run. Below are the hazards associated with flood-damaged vehicles for your careful consideration. Hazards of flood-damaged cars: Firstly, they can severely damage the electronic control systems inside the car. The corrosive nature of mixed rainwater can impair electrical functions, particularly affecting future usage. Here are the relevant details: 1. Flooding height: The severity of a flood-damaged car depends on the water submersion height and whether the vehicle was started while submerged. If the water only reached below the seats, not reaching the vehicle's air intake, fuse box, or central dashboard, the impact on the vehicle is relatively minor after thorough cleaning. 2. Location: At this height, water reaches the transmission, oil pan, and exhaust pipe. Therefore, during cleanup, it's necessary to replace transmission fluid, engine oil, and brake fluid, as well as perform maintenance on the vehicle's braking system, exhaust pipe, and catalytic converter to further mitigate the impact of flooding on subsequent vehicle use.
