Engine oilChecking the engine oil1 Park the vehicle on a level surface
2 Shut the engine off after it has 
reached normal operating tempera-
ture
3 After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean 
lint-free cloth, paper towel, or similar 
material
4 Push the dipstick all the way into the 
guide tube and pull it out again
5 The oil level should be in between the 
two graduations on the dipstick.
As with fuel economy, oil consumption 
is directly influenced by your driving 
style and vehicle operating conditions.380de076
The oil volume between the two marks 
on the dipstick corresponds to approx. 
1.1 US quarts (1 liter). Do not fill to be-
yond the upper mark on the dipstick. 
Excess oil will damage the engine.460de189
Adding engine oilWait until the level has dropped to just 
above the lower mark before adding oil. 
However, do not wait until the oil drops 
below the lower mark.
BMW engines are designed to op-
erate without oil additives. The 
use of additives could lead to damage 
in some cases. This is also true for the 
automatic transmission, the differential 
and the power steering system.< 380de077

Vehicle Identification Number
Power steeringWith the engine off, unscrew the reser-
voir cap and remove the cap with dip-
stick. Then push the dipstick into the 
reservoir again.
The fluid level should be in between the 
marks on the dipstick.
Screw the reservoir cap back on.
Contact your BMW center if the fluid is 
low, as only ATF may be used and spe-
cial knowledge is required for topping 
up.380de078

With the engine shut off, loosen the 
knurled nut and remove the reservoir 
cap.
With the vehicle empty, the fluid level 
should be barely 0.2 in (5 mm) above 
the screen bottom.
Correct the fluid level if required. Al-
ways use Pentosin CHF 11S. 
Position the reservoir cap and tighten 
the knurled nut. Make sure the cover is 
properly seated.380de079
