1. Check the engine oil level. Top up if necessary.
2. Warm up the oil in the automatic transmission to an operating temperature of 50-80°C after approx. 10 minute car ride. Then check the oil level in the automatic transmission. Top up if necessary.
Note: At an ambient temperature of 20°C, after a 10-minute drive in the urban driving cycle, the oil temperature in the automatic transmission rises to 50-80°C.
3. After warming up the automatic transmission, unscrew the plug of the control hole to check the pressure and install a pressure gauge there (special tool ST2505 S001).
Attention:
Remove and install the inspection hole plug with the special tool ST2548 0000.
Since the threads of the plug will be covered with adhesive, do not reuse the removed plug.
