A/C-Heater Blower Motor Fan Speed
A/C-heater blower motor fan speed will need to be calibrated. To calibrate, turn ignition to position II. Turn blower fan switch to maximum, then to minimum. Calibration is complete.
Central Locking System & Courtesy Lighting
Initialize central locking and courtesy lighting by unlocking vehicle using remote control, key or through VADIS (factory scan tool) vehicle communication.
ECM
If connector is disconnected from ECM or battery is disconnected, all adaptation values in control module are erased. DTC memory content will remain intact however. If engine is started after this, a rough, uneven idle can result. In this case, engine must be allowed to run at idle for a few minutes or a longer road test must be performed until adaptation procedure has been completed.
Power Windows
Completely open and close all power windows.

GENERATOR BELT PULLEY (W/FREEWHEEL)
Note. If vehicle is cold, battery charge warning lamp may light shortly after start-up. Freewheel needs to rotate and warm up bearing grease before it locks and engages the rotor shaft. If warning lamp remains lit, it may be an indication that freewheel has not locked pulley to rotor shaft.
Start engine. Raise engine to 3,000 RPM. Ensure power consuming components are connected. Check that only a weak clicking sound is heard when freewheel engages and disengages. Switch off engine. Check that generator rotates for longer than engine.
Rotate pulley counterclockwise and brake heavily. Freewheel should grip generator rotor shaft when rotating counterclockwise. Stop rotation. When stopping pulley, freewheel mechanism should release so that rotor shaft continues to rotate.
