Engine oil Specified engine oilThe quality of the engine oil is 
extremely important for the function 
and life of an engine. Based on exten-
sive testing, BMW has approved only 
certain types of engine oils. 
Use only approved "BMW High Perfor-
mance Synthetic Oil." 
If you are unable to obtain "BMW High 
Performance Synthetic Oil", you may 
use small volumes of other approved 
synthetic oils for topping off between oil 
changes. Use only oils with the specifi-
cation API SH or higher. 
Ask your BMW center for details 
concerning the specific "BMW 
High Performance Synthetic Oil" or 
synthetic oils that have been 
approved.<
You can also call BMW of North America 
at 1-800-831-1117 or visit this website: 
www.bmwusa.com to obtain this 
information.
Viscosity ratings Viscosity is the oil flow rating as estab-
lished in SAE classes.
The selection of the correct SAE class 
depends on the climatic conditions in 
the area where you drive your BMW.
Approved oils are in SAE classes 
5W-40 and 5W-30.<
These kinds of oil may be used for 
driving in all ambient temperatures.

Caring for your vehicleExterior finish To provide effective corrosion protec-
tion, multilayer paintwork is applied at 
the factory. Cataphoretic immersion 
priming techniques are supplemented 
with special body-cavity protectants, 
by applying specially-developed and 
extensively tested materials.
A layer of flexible PVC is first applied 
to the undercarriage. Following this, 
a comprehensive undercoating treat-
ment with a wax-based protectant is 
applied. Regular maintenance makes 
an important contribution to maintaining 
the safety and value of your vehicle.
Increasing awareness of the effects of 
harmful environmental factors on vehi-
cle finishes have led paint and vehicle 
manufacturers to initiate programs 
designed to further improve the durabil-
ity of their finishes. Despite this, envi-
ronmental factors that occur locally or 
regionally can have negative effects on 
the finish of your vehicle. Use the 
factors to determine the frequency and 
extent of your efforts to maintain the 
vehicle finish.Depending upon material and type of 
impact (perforation of paint layer), 
physical stresses from sand, road salt, 
gravel, etc., can cause corrosion to start 
extending beneath the finish, starting at 
the point of impact.
Road dirt, tar spots, dead insects, 
animal droppings (strong alkali effect) 
and tree excretions (resins and pollen) 
all contain substances capable of 
causing damage when allowed to 
remain on the finish of your vehicle for 
any extended period of time (spots, 
etching, flaking, separation in the top 
coat).
In industrial areas, flue dust deposits, 
lime, oily soot, precipitation containing 
sulfur-dioxide (acid rain) and other envi-
ronmental pollutants will damage the 
vehicle's finish unless adequate care is 
provided Ð even though this is generally 
limited to the outside horizontal sur-
faces.In coastal regions, high levels of 
atmospheric salt and humidity promote 
corrosion.
In tropical zones, temperatures of over 
+105 7 (+40 6) in the shade prevail, 
in addition to heavy ultraviolet radiation 
and high humidity. Under those condi-
tions, light paints can reach tempera-
tures up to +175 7 (+80 6) and dark 
paints up to +250 7 (+120 6).
