This is an emergency response, not a roadside repair. Protect the engine and people first.
这是应急处置，不是路边维修；首先保护人员和发动机。
Emergency response · Act immediately · Hazard lights, phone
1. Reduce load and stop safely
Switch off air-conditioning, turn on cabin heat only if safe to do so, and move out of traffic. If the red temperature warning appears or steam is visible, stop and switch off.
降低负荷并安全停车
关闭空调；在安全可行时可短暂开启暖风帮助散热，并尽快驶离车流。红色水温灯亮或看到蒸汽时，立即停车熄火。
2. Do not open the cooling system
Keep clear of steam. Never open a radiator or pressurised coolant cap while hot, and never pour cold water onto a hot engine.
不要打开冷却系统
远离蒸汽；高温时绝不能打开散热器盖或加压冷却液盖，也不能向热发动机直接浇冷水。
3. Call for recovery
Wait in a safe place and arrange towing. A car that overheated can lose coolant again even if the gauge later falls.
联系道路救援
在安全地点等待并安排拖车；即使水温表后来下降，车辆也可能再次缺液或过热。
4. Stop signs
Flashing warning, persistent steam, coolant pouring out, knocking, loss of power or oil-pressure warning means do not restart.
危险信号
警告灯闪烁、持续蒸汽、大量漏冷却液、敲击声、动力丧失或机油压力灯亮时，禁止重新启动。
