Engine oilChecking the oil level 1 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 
dipstick out and wipe it off with a 
clean lint-free cloth, paper towel, or 
similar material.
4 Carefully push the dipstick all the way 
into the guide tube and pull it out 
again.
5 The oil level should be between the 
two marks on the dipstick.
As with fuel economy, oil consumption 
is directly influenced by your driving 
style and vehicle operating conditions.462de244
The oil volume between the two marks 
on the dipstick corresponds to approx. 
1.1 US quarts (1 liter). Do not fill beyond 
the upper mark on the dipstick. Excess 
oil will damage the engine.460de189
To add oil Wait until the level has dropped to just 
above the lower mark before adding oil. 
However, never let the oil drop below 
the lower mark. 
BMW engines are designed to 
operate without oil additives; the 
use of additives could lead to damage 
in some cases. This is also true for the 
manual transmission, the automatic 
transmission, the differential and the 
power steering.<462de245

Engine oil Coolant 
Always observe all environmental 
protection laws when disposing of 
used oil.<
Recommendation: have the oil changed 
by your BMW center only.
Continuous exposure to used oil 
has caused cancer in laboratory 
testing.
For this reason, thoroughly wash any 
areas of skin that come into contact 
with oil using soap and water.
Always store oils, grease and similar 
materials so that they are inaccessible 
to children. Comply with warning labels 
and information on containers.<
Do not add coolant to the cooling 
system when the engine is hot. If 
you attempt to do so, escaping coolant 
can cause burns. 
To avoid the possibility of damage later 
on, never use anything other than 
factory-approved, nitrite and amino-
free extended-duty antifreeze with 
corrosion inhibitor. Your BMW center is 
familiar with the official specifications. 
Antifreeze and anticorrosion agents are 
hazardous to health. You should always 
store it in its original container and in a 
location that is inaccessible to children. 
Extended-duty antifreeze with corro-
sion inhibitor contains ethylene glycol, a 
flammable substance. For this reason, 
do not spill antifreeze with corrosion 
inhibitor on hot engine parts. It could 
ignite and cause burns.<
Comply with the applicable envi-
ronmental laws regulating the 
disposal of extended-duty antifreeze 
with corrosion inhibitor.<
Checking coolant levelCorrect coolant level for cold engine 
(approx. 68 7 or +20 6):
Unscrew the cap from the expansion 
tank.
The coolant level is correct when the 
upper end of the red float is at least 
even with the upper edge of the filler 
neck (refer to the arrow in the illustra-
tion), but no more than 0.8 in (2 cm) 
above it Ð that is, up to the second mark 
on the float (refer also to the schematic 
diagram next to the filler neck).46cde036

The BMW Maintenance System has 
been designed as a reliable means of 
providing maximum driving and operat-
ing safety Ð and as cost-effectively as 
possible for you. 
Please keep in mind that regular main-
tenance is not only necessary for the 
safety of your vehicle, but also plays a 
significant role in maintaining the resale 
value of the vehicle. 
Service Interval DisplayAdvanced technology is employed 
to calculate the optimal maintenance 
intervals. These are then indicated in 
the Service Interval Display. While 
conventional systems rely on distance 
traveled alone to determine when 
service is due, the BMW Maintenance 
System has for years considered the 46cus018
actual conditions under which the 
vehicle operates, because miles can be 
traveled in many different ways:
From a maintenance point of view, 
62,000 miles (100,000 km) of short-
distance urban driving are not equiva-
lent to the same distance covered at 
moderate speeds in long-distance 
highway travel.
The BMW Maintenance System 
includes the Engine Oil Service and 
Inspections I and II.
Determining the maintenance intervals 
according to the actual use of the 
vehicle covers every kind of operating 
situation. However, even those who 
drive only short distances Ð significantly 
less than 6,000 miles (10,000 km) annu-
ally Ð should have the engine oil 
changed at least every 2 years, since oil 
deteriorates over time, regardless of 
use.Service and Warranty Information 
Booklet (US models)/Warranty 
and Service Guide Booklet 
(Canadian models)For additional information on mainte-
nance intervals and procedures, please 
refer to the Service and Warranty 
Information Booklet (US models), or the Warranty and Service Guide Booklet 
(Canadian models).
As a precaution against rust, it is advis-
able to have the body checked for 
damage from rocks or gravel at the 
same time, depending upon operating 
conditions.
Have your BMW center perform 
maintenance and repair. 
Your BMW center is always informed on 
the latest maintenance work and repair 
techniques and equipped with the 
required special tools. In addition, 
checking parts known from experience 
to be subject to wear is a permanent 
part of the maintenance specifications. 
Be sure that all maintenance work is 
confirmed in the Service and Warranty 
Information Booklet (US models), or in 
the Warranty and Service Guide 
Booklet (Canadian models). These en-
tries are your verification for the regular 
maintenance of your vehicle and are 
required for the performance of 
warranty repairs.<
