What Happens If You Make a U-Turn at a Highway Exit?

What is the gear shifting mantra from first to fifth gear?

The gear shifting mantra from first to fifth gear is: For speeds between 10 to 20 km/h, you can use either 1st or 2nd gear; between 20 to 30 km/h, 2nd or 3rd gear can be used; between 30 to 40 km/h, 3rd or 4th gear; between 40 to 50 km/h, 4th or 5th gear; and for speeds above 50 km/h, use 5th gear. As speed increases, the gear should be shifted up accordingly. Failing to do so will keep the engine at high RPM, leading to a rapid increase in fuel consumption. 1st gear is for starting; 2nd gear is a transition gear, suitable for speeds up to about 30 km/h; 3rd to 4th gears are for city driving, suitable for speeds up to 60 km/h; and 5th gear is for fast driving, suitable for speeds above 70 km/h.

What is the reason for the P light being on?

The reasons for the P light being on: 1. ABS function failure; 2. Severe brake pad wear leading to failure; 3. Brake oil not meeting requirements. Abnormalities in the braking system manifest as poor or failed braking, unilateral braking deviation, braking noise, brake drum overheating due to brake drag, parking brake failure, etc. The braking system mainly consists of four parts: the energy supply device, control device, transmission device, and brake. Its main functions are: 1. To decelerate or even stop a moving vehicle; 2. To maintain a stable speed for a vehicle going downhill; 3. To keep a parked vehicle stationary.

How to Replace Brake Fluid in a Car?

The method for replacing brake fluid in a car is as follows: 1. Open the driver's side door of the car and pull the hood release lever located on the left side of the driver's leg area; 2. Lift the car's engine hood upwards and secure it with the support rod, ensuring it is firmly propped to avoid any hazards during the operation; 3. Refill the car's brake fluid up to the MAX level. Brake fluid, also known as hydraulic brake fluid, should be purchased from reliable manufacturers, and the higher the grade, the better. All liquids have the characteristic of being incompressible. In a sealed container or a liquid-filled pipeline, when the liquid is under pressure, it quickly and uniformly transmits the pressure to all parts of the liquid. Hydraulic braking systems operate based on this principle.

What materials are needed to collect the annual inspection sticker for a new car after two years?

To collect the annual inspection sticker for a new car after two years, the following materials are required: 1. Motor Vehicle Inspection Mark Application Form (not required to bring, provided on-site, fill out directly); 2. Motor Vehicle License; 3. Compulsory Traffic Insurance Certificate; 4. Vehicle and Vessel Tax Payment or Tax Exemption Certificate; 5. Owner's ID card. If someone else is handling the process on behalf of the owner, the representative must bring their ID card. For company-owned vehicles, additional documents are needed, including the original vehicle license, duplicate of the compulsory traffic insurance, Organization Code Certificate of the People's Republic of China (with fresh seal), Power of Attorney (with fresh seal), and a copy of the representative's ID card.

What are the symptoms of a dirty fuel injector?

Symptoms of a dirty fuel injector: 1. The throttle response becomes less sensitive, and acceleration is not as smooth as before; 2. The engine noise increases, especially noticeable at low gears and low RPMs; 3. Driving becomes less smooth, the car feels less powerful, and there is a lag when pressing the accelerator. In neutral, the tachometer needle rises slowly; 4. Idling becomes rough, especially noticeable when starting; 5. Fuel consumption increases; 6. The car's emissions exceed standards; 7. In severe cases, it can damage the engine and reduce its lifespan. The fuel injector is one of the key components of an electronic fuel injection engine, designed to atomize gasoline for better combustion. However, due to various factors, carbon deposits can form on the fuel injector. For example, gasoline itself contains impurities that can form sludge-like deposits over time. Additionally, unstable components in gasoline can react at certain temperatures, forming sticky substances like gum and resin. Therefore, it is necessary to clean the fuel injector regularly, typically every 40,000 to 60,000 kilometers.

What Are the Common Engine Faults and Troubleshooting Methods?

Common engine faults include: 1. Mechanical component failure in the engine, where cylinder wear leads to excessively low cylinder pressure; 2. Malfunction of the coolant temperature sensor; 3. Failure of the air flow meter or intake pressure sensor; 4. Malfunction of the throttle position sensor; 5. Excessively high fuel pressure; 6. Fuel injector leakage; 7. Oxygen sensor failure; 8. Ignition system fault; 9. Incorrect valve timing. Engine troubleshooting methods: 1. Inspect for mechanical faults in the engine, check if the exhaust system is blocked, and examine the thermostat in the cooling system; 2. Measure the coolant temperature sensor, ensuring its resistance values at different temperatures meet the standard; 3. Test the air flow meter or intake pressure sensor, verifying their readings comply with the standard; 4. Inspect the throttle position sensor; 5. Measure the fuel pressure.
