Technology for comfort, convenience and safety
94 In the event of a malfunction, the
warning lamp lights up yellow.
Have the system checked and
repaired at your BMW center as soon as
possible.
Check Control messages, refer to page 82.
Please take note of the additional informa-
tion on the Control Display.

Dynamic Drive
The concept
Dynamic Drive minimizes body roll and
optimizes vehicle stability during cornering
and evasive maneuvers.
Active stabilizers at the front and rear axles
form the basis for Dynamic Drive. Suspen-
sion compliance adapts to suit driving con-
ditions, varying from performance-oriented
during cornering to smooth and comfort-
oriented when the vehicle is proceeding in
a straight line.
The system assumes operational status
each time you start the engine.
Driving with Dynamic Drive
During vehicle operation, the system con-
tinuously runs through closed-loop control
cycles lasting only fractions of a second.
In case of malfunction
The symbol will light up, accompa-
nied by a status message in the
Check Control. Please take note of
the additional information on the Control
Display.
You can find more information on the
Check Control starting on page 82.
If the Dynamic Drive system switches
off in response to malfunction, please
remember to adapt your speed accord-
ingly, especially in curves.
The suspension will be noticeably softer
and the vehicle will display a greater ten-dency to tilt during cornering and in cross-
winds.
If a Check Control message stating that
you should stop appears in addition to the
red symbol, stop immediately and switch
off the engine. In this case the oil level in
the reservoir may have dropped below the
minimum, possibly owing to a leak in the
hydraulic system.
Please observe the additional instructions
provided on the Control Display.<
EDC Electronic Damping
Control*
The suspension responds to changes in
factors such as road surface, or operating
conditions such as steering and braking, by
adapting to the new conditions within frac-
tions of a second.
Two programs are available; they can be
selected in the "Settings" menu.
Comfort program
The Comfort program is suitable for use
throughout the vehicle's entire speed range
and regardless of load.
Sport program
You should select the Sport program for
consistently performance-oriented
response from shock absorbers and steer-
ing.

Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as pos-
sible. Always protect tires against all con-
tact with oil, grease and fuels.
Do not exceed the maximum tire inflation
pressure indicated on the side wall of the
tire.
Run-flat tires*
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the
side of the tire. They consist of self-con-
tained tires and special rims. The tire rein-
forcement ensures that the tire retains
some residual safety in the event of pres-
sure drop and driving remains possible to
a restricted degree.
If you switch from summer to winter
tires, or vice versa, use run-flat tires,
as in the event of a breakdown there is no
spare wheel available. In this case, BMW
recommends that you consult your BMW
center. Your BMW center is qualified to
handle run-flat tires and equipped with the
necessary special tools.<
Continuing driving with a damaged
tire
Driving on run-flat tires can continue,
depending on the vehicle load and the
severity of the tire damage, at a maximum
speed of 50 mph/80 km/h.
In the case of complete inflation pressure
loss, 0 psi/kPa, or obvious tire damage,
you can estimate the possible distance for continued driving on the basis of the fol-
lowing guide values:
>With low load:
1 to 2 persons without luggage:
Approx. 150 miles/250 km
>With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
Approx. 90 miles/150 km
>With full load:
More than 4 persons, luggage compart-
ment full:
Approx. 30 miles/50 km.
Drive reservedly and do not exceed
a speed of 50 mph/80 km/h. With
inflation pressure loss, the driving charac-
teristics change, for example reduced track
stability on braking, extended braking dis-
tance, and altered self-steering character-
istics.<
Snow chains*
BMW only tests certain snow chains, clas-
sifies them as road-safe and approves
them. Consult your BMW center for more
information. BMW recommends only using
these approved, narrow-link snow chains.
These snow chains are approved exclu-
sively for use in pairs on the rear wheels,
and should only be mounted on tires
with the dimensions 245/50 R 18. Observe
the manufacturer's instructions when
installing snow chains.Do not exceed a
vehicle speed of 30 mph/50 km/h with the
chains mounted.
After mounting snow chains, do not
activate the Flat Tire Monitor.
When you are driving with snow chains, it
can be beneficial to switch off DSC briefly,
refer to page 93.<

Engine oil
Checking oil level
1.Park the vehicle on a level surface
2.Switch the engine off after it has
reached normal operating temperature 3.After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean lint-
free cloth, paper towel, or similar mate-
rial
4.Carefully push the dipstick all the way
into the guide tube and pull it out again
5.The oil should extend to between the
two marks on the dipstick.
As is the case with fuel economy, the rate
at which the engine uses oil is strongly
influenced by driving style and operating
conditions.

Under the hood
196 The oil quantity between the two marks
of the dipstick is approx. 1.65 US quarts/
1.5 liter. Do not fill beyond the upper mark
on the dipstick. Excess oil can damage the
engine.
Adding engine oil
Wait until the level has dropped to just
above the lower mark or a message
appears in the Check Control before add-
ing oil.
BMW engines are designed to oper-
ate without additives, and their use
could even lead to damage in some cases.
This also applies to the automatic transmis-
sion, the differential and the power steering
system.<
Recommendation: have your oil changed
at your BMW center.
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.
Store oil, grease, etc., well out of the reach
of children; always observe all warning
labels on the containers. and regulations for environmental
protection when disposing of used oil.<
Specified engine oils
The quality of the engine oil selected has
critical significance for the operation and
service life of an engine. BMW approves
only specific oils after confirming their suit-
ability for use in its vehicles with extensive
testing.
Use only approved BMW High Perfor-
mance Synthetic Oil.
If you are unable to obtain BMW High Per-
formance Synthetic Oil, you can add small
amounts of another synthetic oil between
oil changes. Use only oils with the API SH
specification or higher.
Ask your BMW center for details con-
cerning the specific BMW High Per-
formance Synthetic Oil or synthetic oils
which 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 informa-
tion.
Viscosity ratings
Viscosity is the oil flow rating as defined 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.
Antifreeze and anticorrosion agents are
hazardous to health. Always store these
agents in tightly-closed original containers
kept well away from the reach of children.

Maintenance
The BMW Maintenance
System
The BMW Maintenance System is
designed to ensure that your vehicle will
continue to furnish consistent reliability
combined with optimized safety. The ser-
vice schedule also includes operations
related to the vehicle's comfort and conve-
nience features, such as replacement of
the filters for the inside air. The aim is to
optimize maintenance with regard to
reducing the cost of running the vehicle.
Should the day come when you decide to
sell your BMW, you will find that a complete
dealer service history is an asset of inesti-
mable value.
CBS Condition Based Service
CBS is a more advanced version of the
Service Interval Display. Sensors combine
with highly-specialized algorithms to sup-
ply service information that reflects your
vehicle's actual operating conditions more
precisely than ever before.
The system now furnishes individual dis-
plays of the times remaining until the dead-
lines for specific service operations as well
as official state inspections:
>Engine oil
>Brakes: separate for front and rear
>Microfilter/activated-charcoal filter
>Brake fluid
>Spark plugs >Vehicle check
>Coolant
>Official state inspections.
CBS monitors both current and upcoming
service requirements. After accessing the
data stored in the vehicle's key, your BMW
Service Advisor is able to suggest precisely
the right array of service procedures for
your own individual vehicle.
By letting you define a service and main-
tenance regimen that reflects your own
individual requirements, Condition Based
Service builds the basis for trouble-free
driving.
You can find more detailed information
on the Service Interval Display on page 81.

Rules and regulations
California Proposition 65
Warning
California laws require us to issue the fol-
lowing warning:
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the interior
furnishings in a vehicle, contain or emit
chemicals known to the State of California
to cause cancer and birth defects and
reproductive harm. In addition, certain flu-
ids contained in vehicles and certain prod-
ucts of component wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other
reproductive harm.
Battery posts, terminals and related acces-
sories contain lead and lead compounds.
Wash your hands after handling.
Used engine oil contains chemicals that
have caused cancer in laboratory animals.
Always protect your skin by washing thor-
oughly with soap and water.<
OBD connector
The Onboard Diagnostic OBD interface
socket is located on the left of the driver's
side under the instrument panel 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 emission
control system for the vehicle's lifetime.
The system monitors emission-related
components and systems for deterioration
and malfunction.
An indicator lamp informs you of the
need for service, not of the need to
stop the vehicle. However, the sys-
tems should be checked by your BMW
center at the earliest possible opportunity.
Indicator lamp for Canadian mod-
els.
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 center as soon as
possible. Severe engine misfire over only a
short period of time can seriously damage
emissions control components, especially
the catalytic converter.
When the fuel filler cap is not properly
tightened, the OBD system can
detect the vapor leak and the indicator will
light up. If the filler cap is subsequently
tightened, the indicator lamp should go out
within a few days.<
