Where is the sunroof drain outlet of the Mercedes-Benz GLK?

[DelEsther]

The sunroof drain holes of the Mercedes-Benz GLK are located at the four corners of the sunroof, and rainwater is discharged from the A-pillar and C-pillar positions of the car. The maintenance methods for the sunroof are as follows: 1. Talcum powder cleaning: Fine talcum powder can be used for regular cleaning, which can extend the service life of the sealing ring. The moving parts of the sunroof are made of low-maintenance materials, and the mechanical parts should be cleaned regularly with engine oil or lubricant. It is recommended to clean them every two months. 2. Remove sand particles: After prolonged use of the sunroof, a significant amount of sand particles may accumulate in its sliding tracks and gaps. If not removed regularly, these particles can wear out the sunroof components. The sliding tracks should be cleaned frequently to prevent sand particle accumulation and extend the service life of the sunroof sealing ring. Generally, after 2 to 3 months of use, the sealing rubber strips or sliding tracks can be cleaned with gauze soaked in cleaning water. After wiping them dry, apply a small amount of engine oil or butter.
