Paint Drying In Drying Facility Service Information Notes - Si98.00-P-0020A

Model all (CAR, smart) 

Notes on temperature measurement 

A temperature of 80°C in the drying facility corresponds to an object temperature on the vehicle surface of approx. 60°C to 80°C. A check measurement on the component surface can be taken using an infrared temperature measuring instrument.

The following measures must always be performed before drying the paint in the drying facility: 

• The vehicles must be thoroughly cleaned before they are brought into the painting facility.
• Remove grease, tar and wax from the vehicle exterior. Fire extinguishers, spray cans, fuel canisters, CDs, music cassettes, foodstuffs and any other loose, heat-sensitive objects must be removed from the vehicle.
• The recommended drying times for the paints approved by Mercedes-Benz must not be exceeded. All approved materials, technical information and manufacturers are available on the website: https://xentry.mercedes-benz.com at the "Guidelines for paint technology" category.

The following points must additionally be observed in the case of vehicles with high-voltage batteries: 

• It must be ensured that the drying time is not exceeded.
• The battery temperature must be less than 30°C before the drying procedure is started. The maximum length of stay for vehicles in the drying facility must not exceed 60 min at 80°C because otherwise the battery cells may be permanently damaged.
• Remove the ignition key during the drying procedure and put it at a clearly visible location in the vehicle.
• Opening the engine hood opens the engine hood contact switch and deactivates the climate control preconditioning functions.
• The fault memory must be read out and, if necessary, deleted after work has been completed and the vehicle has cooled down.
• On P1 hybrid vehicles (model 221) the state of charge of the high-voltage battery must be grater than 45% before drying the paint in the drying facility. This ensures that the P1-hybrid vehicles (model 221) can be started after paint drying.
• On P2 hybrid vehicles (e.g. model 212, 222) the engine is started using the 12 V battery. A minimum state of charge of the high-voltage battery is not required for the engine to be started.

The following points must additionally be observed in the case of vehicles with gaseous fuel drive or fuel cell: 

• It must be ensured that the drying time is not exceeded.
• On vehicles equipped with a fuel cell, the battery temperature must be less than 30°C before the drying procedure is started. The maximum length of stay for vehicles in the drying facility must not exceed 60 min at 80°C.
• Remove the ignition key during the drying procedure and put it at a clearly visible location in the vehicle.
• On vehicles equipped with a fuel cell, make sure that the H₂ refueling system is at a max. 150 bar (at 15°C). Vehicles are only allowed to be brought into buildings if the H₂ lamp is not  lit.
• When a vehicle with gas system is accepted at service reception, it must be ensured that the system does not leak.
• The fault memory must be read out and, if necessary, deleted after work has been completed and the vehicle has cooled down.
