I've been driving the BYD Han for 5 years and have memorized all the key functions. The leftmost button is the unlock key - a single press opens all doors. Right next to it is the lock button that automatically secures the vehicle when pressed after turning off the engine. The bottom right button controls the trunk - short press to unlock then long press for 2 seconds to lift the trunk lid, preventing accidental operation. The most distinctive circular button is the remote start - press and hold for 3 seconds in winter to pre-start the engine, or activate air conditioning in summer. The key back even has a hidden key ring that releases a mechanical emergency key - such thoughtful detailing! These well-designed functions make driving effortless, especially the remote start which is literally life-saving in Northeast China's sub-zero winter temperatures.

What Causes a Motorcycle to Lack Power and Run Slowly?

Insufficient power and slow speed in motorcycles are usually caused by issues such as damaged cylinder head gasket leaks or the throttle linkage failing to return to position after opening. Precautions for motorcycle riding: When riding in urban areas: The rider should stay focused to accurately judge and handle various situations. Drivers should maintain proper anticipation for different pedestrians. Motorcycles must slow down on muddy roads: Since dirt roads are often uneven, high-speed riding can cause severe jolting, shortening the vehicle's lifespan. Prolonged riding on dirt roads may loosen fastening bolts. Motorcycles can maintain speed on straight roads and short slopes: No need to decelerate or downshift. For sharp turns after uphill climbs or unclear road conditions, riders may accelerate uphill but should slow down near the crest, then proceed after assessing the path.

How Often Should Gear Oil Be Changed in a Car?

Under normal circumstances, the gear oil in a car should be changed every 60,000 kilometers. Here is some relevant information: 1. Changing gear oil can effectively improve the efficiency of gear transmission of engine power. The selection of oil viscosity is the most basic factor when changing oil. If the viscosity is too high, it can cause overheating of the friction surfaces and unnecessary power loss. 2. The commonly used steels for manufacturing car gears include quenched and tempered steel, hardened steel, carburized and quenched steel, and nitrided steel. The strength of cast steel is slightly lower than that of forged steel and is often used for larger-sized gears; gray cast iron has poorer mechanical properties and can be used in lightly loaded open gear transmissions; ductile iron can partially replace steel in gear manufacturing; plastic gears are mostly used in lightly loaded applications where low noise is required, and the paired gears are generally made of steel with good thermal conductivity.
