Most vehicle models require checking when cold. Cold and hot engine readings differ: When cold, the dipstick shows the engine's total oil capacity, while when hot it displays the amount sufficient for lubrication needs. Recommended cold checking: Always check the dipstick when cold to avoid starting the engine without oil. Hot measurements are inaccurate as splashed oil affects readings. Measurement procedure: 1. Remove dipstick and completely wipe clean with tissue 2. Note scale markings 3. Reinsert dipstick fully 4. Remove again - the oil clinging to the tip indicates current level

The following are specific details: Turn off the high-voltage switch before maintenance: If the repair involves the power system during operation, the power supply must be disconnected. To prevent electric shock, it is necessary to wear insulated gloves and insulated shoes, and use insulated tools in accordance with the specified procedures and processes. Follow the safety operation procedures for electrical circuits during maintenance: Due to the characteristics of new energy vehicles, the power battery is the power source of electric vehicles, providing continuous and stable energy for the entire vehicle to ensure normal driving. Currently, ternary lithium-ion batteries are widely used in electric vehicles. The high-voltage electricity in the vehicle's power battery ranges from 380 to 650 volts, so it is essential to follow the safety operation procedures for electrical circuits during maintenance.
