Indicator and warning
lamps
Technology that monitors itself
Indicator and warning lamps that are iden-
tified by
+ are tested for proper functioning
whenever the ignition key is turned. They
each light up once for different periods of
time.
If a fault should occur in one of these sys-
tems, the corresponding lamp does not go
out after the engine is started or it lights up
again while the vehicle is moving. The indi-
cated pages provide information on what
measures to take.

Technology for safety and driving convenience
52 For more information on the various
systems, refer to the "Technology"
brochure.<
Switching off DSC/Activating DTC
Press the DSC button briefly. The DTC indi-
cator lamp comes on and stays on.
DSC has been switched off; DTC is in ready
mode.
In the following exceptional circumstances,
it may be effective to activate the DTC for a
short period:
>When rocking the vehicle or starting off
in deep snow or on loose surfaces
>When driving on snow-covered grades,
in deep snow, or on a snow-covered
surface that has been packed down
from being driven on
>When driving with snow chains.
The gain in traction is achieved by a reduc-
tion in stabilizing intervention.
Switching off DSC and DTC
Hold the DSC switch down for at least
3 seconds. The DSC indicator lamp stays
lit.
In this case, no interventions to increase
stability and traction for the engine and
brakes are carried out.
To maintain vehicle stability, drive
with the DSC switched on whenever
possible.<
Reactivating DSC and DTC
Press the button again.
The indicator lamp goes out.
The laws of physics cannot be
repealed with DSC. It will always be the driver's responsibility to drive in a man-
ner that matches road conditions. We
therefore urge you to avoid using the addi-
tional safety margin of the system as an
excuse for taking risks. Stabilizing interven-
tion is only performed to a limited degree
when the DTC is activated.
Do not make any modifications to the DSC
system. Allow only authorized technicians
to perform service procedures on the
DSC.<
Dynamic Brake Control DBC
If you step on the brake rapidly, this system
automatically produces maximum braking
force boost and thus helps to achieve the
shortest possible braking distance during
panic stops. All of the benefits of the ABS
system are exploited under these circum-
stances.
Do not reduce the pressure on the brake
pedal for the duration of the brake applica-
tion. When the brake pedal is released, the
DBC is deactivated.
For more information on the system, refer
to the "Technology" brochure.
Brake Force Display
The Brake Force Display indicates to the
road user behind you how hard you are
braking.
The display has two levels:
>Normal braking:
Brake lamp 1 lights up on both sides of
the vehicle together with the center
brake lamp.

Refueling

Refueling
Fuel filler door
1.Open fuel filler door
2.Turn the filler cap in a counter-clock-
wise direction
3.Place the filler cap in the bracket on the
filler door.
Releasing manually
If an electrical malfunction occurs, you can
unlock the fuel filler door manually.
1.Remove the covers of the tail lamps by
turning the lock to the right; refer also to
page 87
2.Pull the luggage compartment trim
panel slightly toward the interior.
The green button with the fuel pump
symbol is revealed
3.Undo the adhesive strip and pull off
4.Pull on the knob
Fuel filler cap is released.
Fuel gas cap
Close the gas cap carefully after refu-
eling until a "click" is heard. While closing, be sure not to squeeze the strap
which is fastened to the cap. A loose or
missing cap will activate the "Check gas
cap" lamp.<
Check gas cap
This indicator lamp comes on when
the fuel gas cap is loose or missing.
Close the gas cap tightly as described
above.
Tank capacity: approx. 14.5 gallons /
55 liters, of which approx. 2.1 gallons /
8 liters are reserve capacity.
Simple and environmentally friendly
When handling fuels, comply with all
of the applicable safety precautions
posted at the service station.<
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Pulling the nozzle
out of the pipe during refueling
>results in premature shutoff
>and will reduce the effect of the vapor
recovery system on the pump.
The fuel tank is full when the filler nozzle
shuts off the first time.
Fill the fuel tank before it is com-
pletely empty. Driving to the last drop
of fuel can prevent the engine from operat-
ing properly and result in damage.<
Fuel specifications
The engine uses lead-free gasoline only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI.
AKI = Anti Knock Index.
Do not use leaded fuels. The use of
leaded fuels will cause permanent
damage to the system's oxygen sensor and
the catalytic converter.<

2.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 but no more than ι in / 2 cm
above it, that is, up to the second mark
on the float. Refer also to the schematic
diagram next to the filler neck
3.If necessary, add coolant. Slowly add
coolant until the correct level is reached
– do not overfill.
Comply with the applicable environ-
mental laws regulating the disposal of
extended-duty antifreeze with corrosion
inhibitor.<
Brake fluid
Indicator lamp
The brake warning lamp lights up
red when the parking brake is not
engaged: the brake fluid level is too
low, refer to page 65.
Brake warning lamp for Canadian
models
Brake fluid, refilling
Brake fluid loss may result in extended
brake pedal travel. If this occurs, also refer
to the notes on page 65.
Brake fluid is hygroscopic, that is, it
absorbs moisture from the air over
time.
In order to ensure the brake system's
safety and reliability, have the brake fluid changed every two years by a BMW center.
Refer also to page 48 and the Service Man-
ual.
Brake fluid is toxic and damages the vehi-
cle's paint. You should always store it in the
closed original container and in a location
inaccessible to children.
Do not spill the fluid and do not fill the brake
fluid reservoir beyond the MAX mark. The
brake fluid could ignite upon contact with
hot engine parts and cause serious
burns.<
Comply with the applicable environ-
mental laws regulating the disposal of
brake fluid.<
Brake fluid level
Low brake fluid level in the reservoir com-
bined with extended pedal travel may indi-
cate a defect in one of the brake system's
hydraulic circuits.
BMW recommends that you proceed
to the nearest BMW center. Higher
brake application pressure may be neces-
sary under these conditions, and braking
distances may be significantly longer.
Please remember to adapt your driving
style accordingly.<

Laws and regulations
California Proposition 65
warning
California laws require us to state the fol-
lowing warning:
Engine exhaust, some of its constitu-
ents, and certain vehicle components
contain or emit chemicals known to the
State of California to cause cancer and
birth defects and reproductive harm. In
addition, certain fluids contained in vehi-
cles and certain products 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 interface socket
The Onboard Diagnostic OBD interface
socket is located on the left of the driver's
side behind a specially marked cover
located beneath the instrument panel. The
cover has the letters OBD on it.
This interface makes it possible to access
data on emissions – related components
using special equipment.If the Service Engine Soon indicator
lamp comes on either continuously
or intermittently, this indicates a
fault in the emissions-related electronic
systems. Although the vehicle remains
operational, you should have the systems
checked by your BMW center at the earli-
est possible opportunity.
The illuminated indicator informs you of the
need for service, not that you need to stop
the vehicle. However, the systems should
be checked by your BMW center at the
next opportunity.
If the indicator blinks or flashes, this indi-
cates a high level of engine misfire. Reduce
speed and contact the nearest BMW center
immediately. Severe engine misfiring over
even a short period of time can seriously
damage emission control system compo-
nents, especially the catalytic converter.
Service Engine Soon
warning lamp for Canadian
models.
If the fuel filler cap is not on tight
enough, the OBD system can detect
leaking vapor and the indicator will light up.
If the fuel filler cap is then tightened, the
indicator will usually go out after a short
period of time.<
