For your own safety
Maintenance and repairs
Advanced technology, e.g. the use of
modern materials and high-performance
electronics, requires specially adapted mainte-
nance and repair methods. Have corresponding
work on your BMW performed only by your
BMW center or a workshop that works accord-
ing to BMW repair procedures with appropri-
ately trained personnel. If this work is not
carried out properly, there is a danger of subse-
quent damage and related safety hazards.<
California Proposition 65 Warning
California law requires us to issue the following
warning:
Engine exhaust and a wide variety of
automobile components and parts,

Engine oil temperature gauge
During normal operation, the engine oil temper-
ature is between approx. 1607/706 and
approx. 3407/1706.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 18.5 gallons/
70 liters. You can find information on refueling
on page182.
If the tilt of the vehicle varies for a longer period,
for example when you are driving in mountain-
ous areas, the indicator may fluctuate slightly.
Reserve
After the reserve quantity has been reached, a
message appears for a short time on the Con-
trol Display; the remaining range is shown in the
onboard computer. Below a range of approx.
30 miles/50 km, the message remains on the
Control Display.
Refuel as soon as possible once your
remaining range falls below 30 miles/
50 km; otherwise, engine functions are not
ensured and damage can occur.<
Computer
Displays in instrument cluster
To display the information, press the BC button
in the turn signal lever with the ignition switch at
radio readiness or higher.
The following information is displayed in the
specified order:
>Remaining range
>Average speed
>Average fuel consumption
Remaining range
Displays the estimated remaining range avail-
able with the remaining fuel. The range is pro-
jected based on the driving style over the last
20 miles/30 km.
Refuel as soon as possible once your
remaining range falls below 30 miles/
50 km; otherwise, engine functions are not
ensured and damage can occur.<
Average speed
Periods with the vehicle parked and the engine
off are not included in the calculations of aver-
age speed.
To reset the average speed: press the BC but-
ton in the turn signal lever for approx. 2 sec-
onds.
Average fuel consumption
The average fuel consumption is calculated for
the time during which the engine is running.
You can use the Control Display to view your
fuel consumption rate over two different dis-

Technology for comfort, convenience and safety
88
Dynamic Drive*
The concept
Dynamic Drive minimizes body roll and opti-
mizes vehicle stability during cornering and
evasive maneuvers.
Dynamic Drive is based on active stabilizers on
the front and rear axles. Suspension compli-
ance adapts to suit driving conditions, varying
from performance-oriented during cornering to
smooth and comfort-oriented when the vehicle
is proceeding in a straight line. During vehicle
operation, the system continuously runs
through closed-loop control cycles lasting only
fractions of a second.
The system assumes operational status each
time you start the engine.
Malfunction
The warning lamp lights up yellow and
a message is shown on the Control Dis-
play. There is a malfunction in the sys-
tem. Have the system checked as soon as pos-
sible.
If a malfunction occurs, please remember
to adapt your speed accordingly, espe-
cially in curves.
The suspension will be noticeably softer and
the vehicle will display a greater tendency to tilt
during cornering and in crosswinds.
If a message stating that you should stop is
shown on the Control Display, stop at a suitable
location and switch off the engine as soon as
possible. In this case the oil level in the reservoir
may have dropped below the minimum, possi-
bly owing to a leak in the hydraulic system. Do
not continue driving, but instead contact your
BMW center.<
Flat Tire Monitor FTM
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the tires as you drive. The sys-
tem provides an alert whenever the inflation
pressure drops significantly in relation to the
pressure in another tire.
In the event of a pressure loss, the rolling radius
and therefore the rotation speed of the wheels
change. This change is detected and signaled
as a flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be repeated after
every correction of the tire inflation pres-
sure and after every tire or wheel change.<
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused by
outside factors and does not detect a natural,
even pressure drop in all four tires.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snow-covered or slippery roads
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is auto-
matically continued.
Do not initialize the system when driving with
snow chains

5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.
Load
The permissible load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of occupants, the less cargo/luggage
can be transported.
Stowing cargo
>Load heavy cargo as far forward and as low
as possible, placing it directly behind the
bulkhead behind the rear seats.
>Cover sharp edges and corners.
Securing cargo
>Use the luggage net* or securing straps to
hold down small and lightweight luggage
and cargo.
>Heavy-duty cargo straps
* for securing
larger and heavier objects are available at
your BMW center. Four lashing eyes
mounted in the luggage compartment are
used to secure these heavy-duty cargo
straps, refer to arrows.
>Please observe the special instructions
supplied with the heavy-duty cargo straps.
Always position and secure the load as
described above. If you do not, it can
endanger the passengers during braking or
evasive maneuvers.
When fastening lashings, use only the lashing
eyes, refer to illustration; otherwise, the lash-
ings could come loose or you could damage the
vehicle.
Never exceed the approved gross vehicle
weight or either of the approved axle loads, refer
to page210, as excessive loads can pose a
safety hazard, and may also put you in violation
of freeway safety laws.
You should never transport heavy or hard
objects unsecured in the passenger compart-
ment, as they could fly around and pose a safety
hazard to the vehicle's occupants during abrupt
braking or evasive maneuvers.<
Pad on bottom of luggage
compartment
You can use the pad as needed, for example to
transport soiled objects. The rubberized side is
washable and has an anti-skid effect.

Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Watch speed
Always observe the maximum permissi-
ble speed for the winter tires, otherwise
tire damage may occur, which can result in acci-
dents.<
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels. Do not exceed the maximum
tire inflation pressure indicated on the side wall
of the tire.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Consult your BMW center for more infor-
mation.
These snow chains are approved exclusively for
use in pairs on the rear wheels with the tire size:
>245/50 R 17 Y
>245/45 R 18 Y
Follow the chain manufacturer's instructions
when installing snow chains. Do not exceed a
vehicle speed of 30 mph/50 km/h with the
chains installed.
Do not initialize the Flat Tire Monitor after
installing snow chains as this could cause
the Flat Tire Monitor to malfunction.
When you are driving with snow chains, it can
be beneficial to switch off DTC briefly, refer to
page87.<

Engine oil
Engine oil consumption depends on driving
style and driving conditions.
Checking engine oil level
Your vehicle is equipped with an electronic oil
level check.
The condition for the most accurate indication
of the oil level possible is measurement with the
engine at operating temperature, i.e. following
an uninterrupted drive of at least 6 miles/10 km.
You can display the oil level on the Control Dis-
play while driving or when stopped on a level
surface with the engine running.
iDrive, for principle details, refer to page16.1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.
3.Select "Service" and press the controller.

5.Select "Engine oil level" and press the con-
troller. The oil level is displayed.
Possible messages
>"Engine oil level O.K."
>"No measured value available: Updating
engine oil level measurement...":
Engine oil level is being measured. This
process can take approx. 3 minutes when
stopped on a level surface and approx.
5 minutes while driving.
>"Oil level at the minimum! Refill with 1 quart
engine oil.":
Add 1 quart/liter of engine oil at the next
opportunity.
>"Engine oil level too high":
Have the vehicle checked immedi-
ately; otherwise, engine damage may
result if too much oil has been added.<
>"Please observe recalculated service inter-
val for engine oil":
Do not add engine oil. Continued driving is
possible. To do this, observe the recalcu-
lated remaining mileage until the next oil
change service, refer to page195. Have the
system checked as soon as possible.
Topping off engine oil
Do not add 1 quart/1 liter of oil until a corre-
sponding message appears on the Control Dis-
play.
Add oil within the next 125 miles/200 km,
otherwise engine damage could result.<
Continuous contact with used oil has
caused cancer in laboratory tests.
For this reason, thoroughly wash exposed areas
of skin with soap and water after such work.
Keep oil, grease, etc. out of reach of children
and heed warnings on containers. Failure to do
so could pose health risks.<
Oil change
Have oil changes carried out only by a BMW
center or a repair shop that works in accordance
with BMW guidelines and uses appropriately
trained personnel.
Approved engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Use only approved BMW High Performance
Synthetic Oil.
If BMW High Performance Synthetic Oil is
unavailable, you can add small quantities of
other synthetic oils between oil changes. Use
only oils of the specification API SH or higher.
Your BMW center will be happy to answer
detailed questions on BMW High Perfor-
mance Synthetic Oil or approved synthetic
oils.<
