Automatic transmission car plus and minus signs refer to the manual mode of the automatic transmission. Here are detailed introductions about automatic transmission: 1. The plus sign is for manual upshifting, and the minus sign is for downshifting. The method is: shift to D gear, push the gear lever to the right, and the transmission enters sports mode; use the forward method to shift gears, push forward to upshift, and push backward to downshift; switch to automatic mode by pushing left to the D gear position. 2. The gears of an automatic transmission car are: P is parking gear and starting gear; R is reverse gear; N is neutral gear; D is drive gear, also called driving gear; L is low gear; S is sports mode; OD is overdrive gear.

I was in my early 20s when I first drove an automatic car and was super curious about those + and - signs. Simply put, they're manual mode controls that let you manually shift gears while still in automatic transmission. The + means upshift—press it when speeding up to lower engine RPM and save fuel. The - means downshift, useful for mountain climbs or downhill braking to boost power or use engine braking, preventing overheated brakes. These are usually on the gearshift sides or steering wheel paddles, super easy to use without clutch hassle. I love using them for overtaking—it feels like controlling speed myself, adding fun beyond full-auto mode. Beginners might fumble, but practice in slow city traffic helps. After a few drives, it becomes second nature.

How to Shift Gears in a Lynk & Co 03?

Lynk & Co 03 uses an electronic gear shift. Simply push the gear lever lightly to shift. The upper position of the electronic gear lever is the reverse gear (R). Pushing the lever forward engages reverse, allowing the car to move backward. Pushing the lever backward engages the drive gear (D) for forward movement. The parking gear (P) is operated via a button. Here are the details: 1. The gear positions of an automatic transmission car are relatively simple and very convenient to operate. The P position refers to the parking gear, also known as the parking brake. When the car needs to be parked for a long time, simply press this button to stop the car. Note that the P gear should only be used when the car has come to a complete stop, otherwise it may damage the car's locking mechanism. 2. The R gear represents the reverse gear, used when the car needs to move backward. To engage reverse, first ensure the car is completely stopped, then press the safety button on the shift lever before moving the lever to the R position. The N gear stands for neutral. This gear is not used for long periods and is typically used during brief stops, such as waiting at traffic lights.

How to Fix Automatic Parking System Malfunctions?

Solutions for automatic parking system malfunctions are as follows: 1. Manually move the parking brake to check for loose fixing screws, deformed operating levers, loose fixing pins, or damaged operating lever springs. If any of these issues are found, repair and adjust them promptly. 2. After driving for a while, touch the surface of the brake drum by hand. If it is excessively hot, it indicates that the gap with the brake drum is too small. In this case, simply readjust the gap. 3. Pull the parking brake lever to the braking position and release it. Then, grip and release the lever handle to perform up-and-down movement tests to check if the lever is bent, stuck, or if the spring is broken. If no issues are found, immediately take the vehicle to a repair shop for maintenance.

How to Deal with a Tire Blowout at High Speed?

Here are the methods to handle a tire blowout at high speed: 1. If the front tire blows out, firmly grip the steering wheel to adjust the direction of the car. Avoid repeatedly jerking the steering wheel or slamming on the brakes. Wait until the vehicle gradually slows down before gently steering to a stop. Then, set up a warning triangle behind the car to prevent secondary accidents. 2. If the rear tire blows out, gradually reduce speed by easing off the accelerator and downshifting to bring the car to a gentle stop. 3. To ensure even tire wear on the same vehicle, perform a tire rotation every 5,000 kilometers and a four-wheel alignment every 5,000 to 10,000 kilometers to prevent abnormal or excessive tire wear. Additionally, it is not allowed to install tires of different models or with significant differences in wear on the same axle.
