Dynamic Stability Control (DSC)
*
Deactivating the DSC/activate the 
ADBPress the DSC button briefly; the indi-
cator lamp comes on and stays on.
DSC is deactivated; ADB is operational.
In the following rare situations, it may 
prove useful to activate the ADB for a 
brief 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.
Under these special circumstances 
traction is increased by deactivating the 
control systems that enhance traction 
under normal conditions.
Deactivating the DSC and ADB Hold the DSC button down for at least 
3  seconds. The indicator and the yellow 
brake warning lamps will remain on 
continuously.
The systems for enhancing stability and 
traction are deactivated, and there is no 
active braking intervention or torque 
control.
To maintain vehicle stability, 
always drive with the DSC acti-
vated whenever possible.
lamp or the indicator lamps will go out.
The laws of physics cannot be 
repealed, even with DSC. It will 
always be the driver's responsibility to 
drive in a manner that matches road 
conditions. This is why you should not 
use the additional safety margin the 
system provides as an excuse to take 
risks.
When ADB is in its standby mode, DSC 
is deactivated; DSC does not intervene 
to enhance vehicle stability under these 
conditions.
Do not make any modifications to the 
DSC system. Allow only authorized 
technicians to perform service proce-
dures on the DSC.<
Dynamic Brake Control (DBC)DBC is an integral component of the 
DSC system.
The system responds to sudden, high-
intensity applications of force to the 
brake pedal by automatically braking 
the vehicle with maximum boost to 
achieve the shortest-possible braking 
distances during "panic stops." This 
system exploits all the benefits of ABS.
Do not reduce the pressure exerted 
against the brake pedal until the 
braking maneuver has been completed. 
DBC is deactivated when you release 
the brake pedal.

Flat Tire Monitor
*
The conceptAs you drive, the Flat Tire Monitor 
keeps track of pressure levels in all four 
tires in order to detect and warn of any 
substantial pressure loss. 
The system actually detects pressure 
loss by monitoring differences in the 
relative speeds of the four wheels. It 
interprets variations outside specified 
limits as severe pressure loss, and then 
responds by generating a warning.
Initializing the systemInitializing is necessary to familiarize the 
system with the correct inflation pres-
sure.
Repeat this process after any changes 
in tire inflation pressure, tire rotation or 
replacement. Do not carry out further 
system initialization after adjusting the 
inflation pressure and letting the system 
"learn" the correct pressures.
1. Check the tire inflation pressures in 
all the tires, comparing them with the 
inflation pressure chart on page 25 
and adjusting their pressure if neces-
sary
2. Turn the ignition key to position 2
3. Press the button as long as you need 
to until the indicator lamp on the 
instrument cluster lights up. After a 
little while, the indicator lamp will go 
out by itself
4. After a few minutes driving time, the 
Flat Tire Monitor adopts the current 
pressure levels as the reference, and 
from that point on, can detect and 
report a flat tire.

Flat Tire Monitor
*
To activate/deactivate the systemThe Flat Tire Monitor automatically 
assumes operation whenever you turn 
the ignition key to position 2. Unless 
manually deactivated, it is always on 
during normal vehicle operation.
To deactivate the system: press the 
button, the yellow indicator lamp comes 
on.
To activate the system: press the 
button again, the indicator lamp goes 
out.
You should deactivate the system 
before driving with snow chains, as the 
chains can generate spurious warnings 
and/or prevent the system from 
detecting actual pressure loss. 
Flat tire warning
The red warning lamp in the 
instrument cluster lights up to 
warn of pressure loss and tire 
failure. This visual alert is accompanied 
by an acoustic warning signal. Reduce 
your speed immediately, and steer and 
brake gently as you bring the vehicle to 
a stop. 
To reset the warning lamp: after 
replacing the damaged tire you will 
need to reset the red warning lamp 
manually: maintain pressure on the Flat 
Tire Monitor button until the warning 
lamp goes out. Then reinitialize the 
system.
The Flat Tire Monitor cannot 
provide you with advance warning 
of sudden and severe tire damage 
caused by external factors.
The system also does not detect the 
gradual and minor loss of pressure that 
all tires display over extended periods 
of time.<
Check tire inflation pressures on a 
regular basis, correcting them as 
necessary, refer to page 24.
The system may respond to operation 
on slippery or snow-covered road 
surfaces with false warnings or delays 
in detecting actual pressure loss.
Performance-oriented driving (slip at 
the drive wheels, high rates of lateral 
acceleration) can also increase the time 
that the Flat Tire Monitor requires to 
detect a flat.<
System malfunctionsThe yellow indicator lamp in the instru-
ment cluster lights up and remains on 
until the problem is corrected.
Please refer the problem to your BMW 
center.

Parking lamps/Low beamsParking lamps
The front, rear and side vehicle 
lighting is switched on. You can 
use the parking lamps for 
parking. For lighting on one side for 
parking as an additional feature, refer to 
page 78.
Low beams
When the ignition is switched off 
while the low beams are on, the 
headlamps go out and only the 
parking lamps remain on.
FOLLOW ME HOME lamps:
When you activate the headlamp 
flasher after parking the vehicle with the 
lights turned off, the low-beam head-
lamps will come on for a short time. You 
can also have this function deacti-
vated.<
LIGHTS ON warningWhen you open the driver's door, after 
having turned the ignition key to posi-
tion 0, you will hear an acoustic signal 
for a few seconds to remind you that 
the lamps have not been switched off.Daytime driving lamps

If you desire, the light switch can be left 
in the second position: 
When the ignition is switched off, the 
external lighting is also switched off.
You can have the activation 
settings for the daytime driving 
lamps programmed on your vehicle.<
Automatic headlight control
* 
When the switch is set to this 
position the system automati-
cally activates and cancels the 
low beams in response to changes in 
ambient light ( in tunnels, at dusk, etc.) 
as well as rain and snow.
The vehicle's external lights 
remain on constantly when you 
switch on the front fog lamps after the 
headlights have come on automati-
cally.< 
Automatic headlight control 
cannot serve as a substitute for 
the driver's judgement in determining 
when the vehicle lights should be 
switched on. For example, the sensors 
are not able to detect fog. To avoid 
safety risks, you should respond to 
these kinds of low-visibility situations 
by switching the headlights on manu-
ally.< You can have the sensitivity of 
your vehicle's automatic head-
light control adjusted.<

Engine 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 oil, grease, etc., out of 
reach of children. Comply with all 
warning labels and information on 
containers.<
Comply with the applicable envi-
ronmental laws regulating the 
disposal of used oil.<
Specified engine oilsThe quality of the engine oil is 
extremely important for the operation 
and service life of an engine. Based on 
extensive testing, BMW has approved 
only certain grades of engine oil.
Use only approved "BMW High 
Performance Synthetic Oil." 
If you are unable to obtain an approved 
"BMW High Performance Synthetic 
Oil," you may use small volumes of 
other synthetic oils for topping up 
between oil changes. Use only oils with 
the specification API SH or higher. 
Ask your BMW center for details 
concerning the specific "BMW 
High Performance Synthetic Oil" or 
synthetic oils that 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 information.
Viscosity ratings Viscosity is the oilflow rating as estab-
lished in SAE classes.
The selection of the correct SAE class 
depends on the climatic conditions in 
the area where you drive your BMW.
Approved oils are in SAE classes 
5W-40 and 5W-30.<
These kinds of oil may be used for 
driving in all ambient temperatures.

Brake fluidWarning lamp
The brake warning lamp comes 
on when the parking brake is 
not engaged: the brake fluid 
level is too low, refer to page 17.
Brake warning lamp for Cana-
dian models.
Adding brake fluidFor adding brake fluid or for deter-
mining and correcting the cause of 
brake fluid loss, consult your BMW 
center. Your BMW center is familiar 
with the specifications for factory-
approved brake fluids (DOT 4).
Brake fluid loss may result in extended 
brake pedal travel. Refer to the informa-
tion on page 100.
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 65 and 
to the Service and Warranty Information 
Booklet (US models) or the Warranty 
and Service Guide Booklet (Canadian 
models). 
Brake fluid is toxic and damages the 
vehicle's paint. You should always store 
it in its original container and in a loca-
tion which is out of reach of 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 envi-
ronmental laws regulating 
the disposal of brake fluid.<

Light-emitting diodes (LEDs)Light-emitting diodes installed behind 
translucent lenses serve as the light 
source for many of the controls and 
displays in your vehicle. The concept 
behind their operation is related to that 
employed for conventional lasers.
Do not remove the protective lens 
and avoid staring directly at the 
unfiltered beam for extended periods 
(several hours), as inflammation of the 
iris could result.<
California laws require us to state the 
following warning:
Engine exhaust, some of its 
constituents, and certain vehicle 
components contain or emit chemicals 
known to the State of California to 
cause cancer and birth defects or other 
reproductive harm.<

OBD interface socketThe interface socket for onboard diag-
nostics is located on the left-hand side 
of the driver's side, on the underside of 
the instrument panel and under a cover 
panel. The cover has the letters OBD on 
it.
This interface makes it possible to 
access data on emissions-related 
components using special equipment.
An 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 
earliest possible opportunity.
If the indicator blinks or flashes, this 
indicates 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 components, 
especially the catalytic converter.
Service Engine Soon warning

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.<
