	Risk of accident  caused by vehicle starting off by itself when engine is running. Risk of injury  caused by contusions and burns during starting procedure or when working near the engine as it is running	Secure vehicle to prevent it from moving by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.	AS00.00-Z-0005-01A
	The vehicle must  be positioned horizontally on its wheels, otherwise measurement errors will occur.
	Check and pour in transmission oil when cold (approx. 25 °C)
1	Remove engine cover.	Only if required
2	Remove locking pin (93a) and take plug (93) off oil filler pipe	To do so, break off the plate of the locking pin (93a) using a suitable tool and remove the pin remaining in the cap (93) by pressing downwards.
3	Fill with transmission oil	After a complete refill and after changing the transmission oil, pour in approx. 5 liters of transmission oil before starting the engine. Insufficient and excessive quantities of oil can result in malfunctions and transmission damage.

4	Start engine and allow it to idle briefly in gear range "P"
5	Fill with remaining quantity of transmission oil	Only with complete refill	*BF27.00-P-1001-01C
6	Actuate service brake and briefly shift through gear ranges several times with vehicle stationary and engine running at idle speed, then reengage gear range "P"
7	Insert oil dipstick all the way into oil filler pipe, pull it out again and read off transmission oil level	When cold, the transmission oil level must be between the "min" and "max" marking in the range (A).	Fig 3
8	Correct transmission oil level	If necessary Insufficient and excessive quantities of oil can result in malfunctions and transmission damage.

9	Check transmission oil level again	After pouring in transmission oil.
	Only perform steps 10 to 14 if shifting problems occur.	Precise checking is only possible at a transmission oil temperature > 80 °C.
10	Connect Star Diagnosis and check transmission oil temperature in gear range "R" or "D"	Operate the service brake when doing so.
11	Start engine and allow it to idle in gear range "P"
12	Insert oil dipstick all the way into oil filler pipe, pull it out again and read off transmission oil level	The transmission oil level must be between the "min" and "max" marking in the range (B).	Fig 3
13	Correct transmission oil level	If necessary Insufficient and excessive quantities of oil can result in malfunctions and transmission damage.
