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 MercedesBenz 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 H2 lamp is not lit.
When a vehicle with gas system is accepted at service reception, it must be ensured that the system is leaktight.
The fault memory must be read out and, if necessary, deleted after work has been completed and the vehicle has cooled down.
