Washer fluid Engine oilWindshield and headlamp washer
system Approximate capacity is 8.2 quarts/
7.8 liters.
Fill with water and — if required — with
the addition of a washer antifreeze,
according to manufacturer's recom-
mendations.
We recommend that you mix the
washer fluid before adding it to
the reservoir.<
Antifreeze agent for the washer
systems is inflammable. For this
reason, keep it away from sources of
flame and store it only in its original
containers. Store it so that it is inacces-
sible to children. Comply with the
instructions on the containers.< 530de298
Checking oil level 1. Park the vehicle on a level surface
2. Switch 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 carefully all the way
into the guide tube and pull it out
again
5. The oil level should be in between
the two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions. 530us100
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.
X5 4.8is:
With a very sporty driving style, the
engine oil level should be at the upper
mark on the dipstick.530us205

Engine oil Adding engine oil Wait until the level has dropped to just
above the lower mark before adding oil.
Continuous exposure to used oil
has caused cancer in laboratory
testing. For this reason, any skin areas
that come into contact with oil should
be thoroughly washed with 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.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of used oil.< 530de326
Specified engine oils The quality of the engine oil selected
has critical significance for the opera-
tion and service life of an engine.
Based on extensive testing, BMW has
approved only certain engine oils.
Use only approved BMW High Perfor-
mance Synthetic Oil.
If you are unable to obtain BMW High
Performance Synthetic Oil, you can add
small amounts of synthetic oil in
between oil changes. Use only oils with
the API SH specification or higher.
Ask your BMW Sports Activity
Vehicle center for details concern-
ing the specific BMW High Perfor-
mance Synthetic Oil or synthetic oils
which have been approved.<
You can also call BMW of North Amer-
ica at 1-800-831-1117 or visit this web-
site: www.bmwusa.com to obtain this
information.
BMW engines are designed to
operate without additives, and
their use could even lead to damage in
some cases.<
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 typically drive your
BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.

Coolant
Do not add coolant to the cooling
system when the engine is hot.
Escaping coolant can cause burns.<
Coolant consists of water and coolant
additive. Not all commercially available
additives are suitable for your BMW.
Ask your BMW Sport Activity Vehicle
center for suitable additives.
Only use suitable additives, as
otherwise engine damage may
result. The additives present a health
hazard.<
Always observe all applicable
environmental rules and regula-
tions when disposing of used coolant
additives.<
Checking coolant level 1. The engine must be at ambient tem-
perature
2. Start by turning the cap of the expan-
sion tank counter-clockwise. Pause
to allow any accumulated pressure to
escape, then open
3. The coolant level is correct when the
end of the red float is aligned with
the upper edge of the filler opening,
refer to the arrow in the illustration,
or max. 0.8 in/2 cm higher, i. e. up to
the mark on the float, refer also to the
schematic diagram, next to the cap530us102
4. If the coolant is low, slowly add cool-
ant up to the specified level – do not
overfill
5. Twist closed the cap and tighten
firmly
6. Have the reason for the coolant loss
eliminated as soon as possible.

Brake fluidBrake fluid level
If the warning lamp lights up
or the message "CHECK
BRAKE FLUID" appears in the
Check Control: stop immedi-
ately. The brake fluid in the res-
ervoir has fallen to below the
minimum level.
Add brake fluid The brake fluid reservoir is located
under the microfilter housing trim panel
on the driver's side of the vehicle. For
adding brake fluid or for determining
and correcting the cause of brake fluid
loss, consult your BMW Sports Activity
Vehicle center. Your BMW Sports
Activity Vehicle center is familiar with
the specifications for factory-approved
DOT 4 brake fluids.
Brake fluid loss may result in extended
brake pedal travel. For this situation,
refer to the notes on page 139.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
a BMW Sports Activity Vehicle center.
Refer also to the Service and Warranty
Information Booklet for US models or
the Warranty and Service Guide Book-
let for Canadian models.
Brake fluid is toxic and also damages
vehicle paintwork. Always store these
agents in tightly-closed original con-
tainers kept well away from the reach of
children.
Do not spill the fluid and do not refill the
brake fluid reservoir to beyond the MAX
mark. The brake fluid could ignite upon
contact with hot engine parts and
cause serious burns.<
Always observe all applicable
environmental rules and regula-
tions when disposing of used brake
fluid.<

The BMW Maintenance System is
designed in such a way that it reliably
ensures the road safety and operating
reliability of the vehicle, keeping the
cost for you as low as possible.
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 Display Conventional systems rely solely on
distance traveled to determine when
service is due. The BMW Maintenance
System, on the other hand, began many
years ago to take the actual conditions
under which the vehicle is driven into
consideration. After all, different drivers 390us008
can accumulate mileage in very differ-
ent ways:
From the point of view of maintenance,
62,000 miles/100,000 km accumulated
in short-distance urban driving are not
the equivalent of 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 loads on the
vehicle covers every kind of operating
situation. However, even those who
drive only short distances, significantly
less than 6,000 miles/10,000 km annu-
ally, should have the engine oil changed
at least every 2 years since oil deterio-
rates over time, regardless of use. Service and Warranty Information
Booklet for US models/Warranty
and Service Guide Booklet for
Canadian models For additional information on mainte-
nance intervals and procedures, please
refer to the Service and Warranty Infor-
mation Booklet for US models or the
Warranty and Service Guide Booklet for
Canadian models. As a precaution against corrosion, it is
advisable to have the body checked for
damage from rocks or gravel at the
same time, depending upon operating
conditions.
Have your BMW Sports Activity
Vehicle center do the mainte-
nance and repair.
Be sure that all maintenance work is
confirmed in the Service and Warranty
Information Booklet for US models or
the Warranty and Service Guide Book-
let for Canadian models.
These entries will constitute your proof
that the vehicle has received regular
maintenance. They are also required for
warranty claims.<

Proposition 65 Warning California laws require us to state the
following warning:
Engine exhaust and a wide variety
of automobile components and
parts, including components found in
the interior furnishings in a vehicle, con-
tain or emit chemicals known to the
State of California to cause cancer and
birth defects and reproductive harm. In
addition, certain fluids contained in
vehicles and certain products of com-
ponent wear contain or emit chemicals
known to the State of California to
cause cancer and birth defects or other
reproductive harm. Battery posts, ter-
minals and related accessories contain
lead and lead compounds. Wash your
hands after handling.
Used engine oil contains chemicals that
have caused cancer in laboratory ani-
mals. Always protect your skin by
washing thoroughly with soap and
water.<
Event Data Recorders Your vehicle may be equipped with one
or more sensing and diagnostic mod-
ules or a recording device capable of
recording or transmitting certain vehicle
data or information. In addition, if you
have a Subscription Service Agreement
for the BMW Assist system, certain
vehicle information may be transmitted
or recorded in order to provide such
services.
The interface socket for the Onboard
Diagnostic is located on the left of the
driver's side at the bottom of the instru-
ment cluster and under a cover. The
cover has the letters OBD on it.
The purpose of the OBD system is to
ensure proper operation of the emis-
sion control system for the vehicle's
lifetime. The system monitors emission-
related components and systems for
deterioration and malfunction.

An illuminated indicator lamp
informs you of the need for ser-
vice, not of the need to stop the
vehicle. However, the systems should
be checked by your BMW Sports Activ-
ity Vehicle center at the earliest possi-
ble opportunity.
Display of the previously
described malfunction on Cana-
dian models.
Under certain conditions, the indicator
lamp will blink or flash. This indicates a
rather severe level of engine misfire.
When this occurs, you should reduce
speed and consult the nearest BMW
Sports Activity Vehicle center as soon
as possible. Severe engine misfire over
only a short period of time can seriously
damage emission control components,
especially the catalytic converter.
When the filler cap is not properly
tightened, the OBD system can
detect the vapor leak and the indicator
lamp will light up. If the filler cap is sub-
sequently tightened, the indicator lamp
should go out within a few days.<
