1. Confirm the sound source
Open slowly while listening at upper hinge, lower hinge and check strap. A sagging, clicking or loose door needs hinge inspection, not lubricant.
确认声音来源
缓慢开门分别听上下铰链和限位器；门下沉、咔嗒或松动需要检查，不能只靠润滑。
2. Protect surrounding surfaces
Ignition off, car secure and wind calm. Place cloth behind the target so overspray cannot reach paint, seals or cabin trim.
保护周边表面
熄火并固定车辆，在无强风处操作；目标后垫布，防止喷到车漆、密封条与内饰。
3. Apply a minimal correct product
Clean grit first, then place one small amount on the exposed pivot specified by the manual. Do not flood electrical connectors.
少量使用正确产品
先清除砂尘，再按手册在外露转轴少量点涂，不要淹没电气插头。
4. Cycle and remove excess
Move the door several times while controlled, wipe all excess and verify the door latch and check strap operate normally.
活动并擦净余量
控制车门来回活动数次，擦净所有多余润滑剂，并确认门锁与限位器正常。
