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 can be found on the website: http://aftersales.mercedes-benz.com  under "Guidelines for paint technology".

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 lower  than 30 °C before the drying procedure is started. The maximum time that the vehicles can remain in the drying facility must not exceed 60 min at 80 °C, otherwise the battery cells can 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 charge level of the high-voltage battery must be higher  than 45 % before paint drying in the drying facility. This ensures that the P1-hybrid vehicles (model 221) can be started after paint drying.
• P2 hybrid vehicles (e.g. model 212, 222) start the engine via the 12 V battery. A minimum charge level 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 with fuel cell, the battery temperature must be lower than 30 °C before the drying procedure is started. The maximum time that the vehicles are permitted to remain 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, it must be ensured that the H2 tank pressure is max. 150 bar (at 15 °C). Vehicles are only allowed to be brought into buildings if the H 2 lamp is not lit.
• When a vehicle with gas system is accepted at service reception, it must be ensured that the system is leak tight.
• The fault memory must be read out and, if necessary, deleted after work has been completed and the vehicle has cooled down.
