Under these special circumstances
traction is increased by deactivating the
control systems that enhance traction
under normal conditions.Deactivating the DSC and the
DTCPress the DSC button as long as you
need to until the indicator lamp and the
yellow brake warning lamp light up, but
no more than 10 seconds.
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. or the indicator lamps will go out. DTC
is deactivated.
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repealed even with DSC.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.
Whenever the DTC is activated, the
DSC is switched off and DTC performs
minor stabilizing intervention.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
Flat Tire Monitor*The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires. The system alerts you whenever
the inflation pressure of a tire falls sig-
nificantly below the pressure of another
tire.
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.Functional requirementsIn order for the Flat Tire Monitor to learn
the correct tire inflation pressure,
please do the following:
1. Check the tire inflation pressures in
all tires
2. Compare them with the tire inflation
pressure table, refer to page 116,
and correct them, if necessary
3. Initialize the system.
Dynamic Stability Control (DSC)

System limitations
The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors and does not detect
the balanced and very gradual pressure
loss that takes place in all four tires
over an extended period of time.<
On the other hand, the following situa-
tions can lead to a delayed detection of
pressure loss and even to the system
not functioning:
>Driving on snow-covered or slippery
roads
>Performance-oriented driving: slip at
the drive wheels, high levels of lateral
acceleration
>When driving with snow chains, false
warnings and undetected pressure
losses may occur
>When driving with a space-saver
spare tire, the Flat Tire Monitor can-
not function.
Initializing the system
Each time you correct the pres-
sure in a tire, or change a wheel or
tire, reinitialize the system immediately
afterwards. This requires a bit of driv-
ing.<
1. Before driving off, start the engine
but do not start driving
2. Press the button as long as you need
to, but no more than 10 seconds,
until the indicator lamp in the instru-
ment cluster lights up in yellow for a
few seconds
3. Drive off.
It takes a few minutes before the Flat
Tire Monitor can detect a flat tire and
issue a warning.
When driving with snow chains or
a space-saver spare tire, do not
initialize the system.<
Flat tire
The indicator lamp in the instru-
ment cluster lights up red. This
visual alert is accompanied by
an acoustic warning signal.
1. Carefully reduce speed and come to
a stop. Avoid sudden braking and
steering maneuvers
2. Determine which wheel is damaged
If this cannot be determined, con-
tact your BMW center.<
3. Replace the damaged wheel, refer to
Changing a wheel on page 141.
After replacing the damaged tire, initial-
ize the system.
Vehicles with Run Flat tires:
1. Carefully reduce your speed to under
50 mph / 80 km/h. Avoid sudden
braking and steering maneuvers. Do
not exceed a speed of 50 mph /
80 km/h

85 Lamps
Parking lamps/Low beamsParking lamps
The front, rear and side vehicle
lighting is switched on. You can
use the parking lamps to signal
the position of the vehicle when it is
parked. For lighting on one side for
parking as an additional feature, refer to
page 87.
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 lampsWhen 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
deactivated. 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 igni-
tion is switched off, the external lighting
is also switched off.
You can have the activation set-
tings for the daytime driving lamps
programmed on your vehicle.<
Automatic headlamp 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, for example in tunnels, at
dusk, and when it is raining or snowing.
The low-beam headlamps remain
on, regardless of the ambient
light, when you switch on the fog
lamps.<
Automatic headlamp control can-
not 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
headlamps on manually.<
You can have the sensitivity of
your vehicle's automatic head-
lamp control adjusted.<

Adding engine oilOnly add engine oil when the oil level
has dropped to just above the lower
mark on the dipstick.
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 oils, grease and similar materials
so that they are inaccessible to chil-
dren. Comply with warning labels and
information on containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of used oil.<
Recommendation: have the oil changed
at your BMW center.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 Perfor-
mance Synthetic Oil.
If an approved BMW High Performance
Synthetic Oil should be unavailable, you
may use small amounts of other syn-
thetic oils for topping up between oil
changes. Use only oils with the specifi-
cation API SH or higher.
Ask your BMW center for details
concerning the specific BMW
High Performance Synthetic Oil or syn-
thetic oils that have been approved.<
BMW engines are designed to
operate without oil additives; the
use of additives could even lead to
damage in some cases.<
You can also call BMW of North Amer-
ica toll-free at 1-800-831-1117 or visit
this website: www.bmwusa.com to
obtain this information.Viscosity ratingsViscosity 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 driv-
ing in all ambient temperatures.

Coolant
Do not add coolant to the cooling
system when the engine is hot. If
you attempt to do so, escaping coolant
can cause burns.<
Coolant consists of water as well as an
additive such as antifreeze with corro-
sion inhibitor. Not all commercially
available additives are suitable for your
BMW. Your BMW center knows which
additives are appropriate.
Only use approved additives, as
the engine could otherwise be
damaged. The additives are hazardous
to your health; therefore, follow the
instructions on the containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of antifreeze with corrosion inhib-
itor.<
Checking the coolant level and
adding coolantCheck the coolant level when the
engine is cold, approx. 687/+206.
1. Open the cap for the expansion tank
by turning it slightly counterclock-
wise to allow accumulated pressure
to escape. Then open
2. The coolant level is correct when the
upper end of the red float rod is at
least even with the upper edge of the
filler neck; see arrow. The end of the
float may stick out by a maximum of
3/4 in/2 cm – that is, up to the sec-
ond mark on the float
3. If necessary, add coolant. If the cool-
ant is low, slowly add coolant until
the correct level is reached – do not
overfill.
Brake fluidIndicator lamp
The warning lamp comes on
even though the parking brake
is released:
The brake fluid level in the reservoir is
too low, refer to page 18. At the same
time, there may be significantly greater
pedal travel. Have the system checked
as soon as possible.
Warning lamp for Canadian
models.
If you continue driving, extended
pedal travel may be necessary
and braking distances may be signifi-
cantly longer. Be sure to adapt your
driving style accordingly.<

132Laws and regulations
California lawsProposition 65 warningCalifornia 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, terminals and related
accessories contain lead and lead com-
pounds. Wash your hands after hand-
ling.
Used engine oil contains chemicals that
have caused cancer in laboratory ani-
mals. Always protect your skin by
washing thoroughly with soap and
water. 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.
OBD interface socketThe interface socket for onboard diag-
nostics is located on the left-hand side
of the driver's side, below the instru-
ment 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 com-
ponents using special equipment.
An illuminated indicator informs
you of the need for service, not
that you need to stop the vehi-
cle. 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

133
engine misfiring for even a short period
of time can seriously damage emission
control system components, especially
the catalytic converter.
Service Engine Soon warning
lamp for Canadian models.
If the gas cap is not on tight
enough, the OBD system can
detect leaking vapor and the indicator
will light up. If the gas cap is then tight-
ened, the indicator will usually go out
after a short period of time. OverviewControlsMaintenanceRepairsDataIndex

License plate lamps5 watt bulb
1. Place a screwdriver in the slot and
press toward the left to release the
lens
2. Replace the bulb.Light-emitting diodesLight-emitting diodes (LEDs) installed
behind translucent lenses serve as the
light sources for many of the controls
and displays in your vehicle. These
light-emitting diodes are related to con-
ventional lasers, and legislation defines
them as light-emitting diodes, Class 1.
Do not remove the protective lens,
and avoid staring directly at the
unfiltered beam for several hours, as
inflammation of the retina could
result.<
Changing a wheel
Safety precautions in the event of
a flat tire or wheel change:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat sur-
face. Switch on the hazard warning
flashers. Turn the steering wheel to the
straight-ahead position and engage the
steering lock. Shift into 1st or Reverse,
or if you have an automatic transmis-
sion position the selector lever in Park,
and engage the parking brake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area, behind a guardrail,
for example.
If a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all local safety guidelines and reg-
ulations.
Change the wheel only on a level, firm
surface which is not slippery. Avoid
jacking the vehicle on a soft or slippery
support surface – snow, ice, loose
gravel, etc. – as either the vehicle or the
jack could slip sideways.
Position the jack on a firm support sur-
face.
Do not place wooden blocks or similar
objects under the jack. They could pre-
vent the jack from extending to its full
Lamps and bulbs

Towing and tow-starting the vehicle
Always observe all applicable
towing laws and regulations.<
Using the towing eyeletThe screw-in towing eyelet is located in
the luggage compartment under the
floor panel; be sure that it remains with
the vehicle at all times. It can be
attached at the front or rear of your
BMW.
Observe the following instruc-
tions in order to avoid damaging
the towing eyelet or the vehicle: use
only the towing eyelet supplied with the
vehicle, and screw it in firmly until it
stops. Use the towing eyelet for towing
on paved roads only. Avoid subjecting
the towing eyelet to lateral loads, e.g.
do not lift the vehicle using the towing
eyelet.<
Access to the threaded socketPress out the cover in the front or rear
bumper with a screwdriver at the top of
the recess.Being towed
Make sure that the ignition key is
in position 1, because the steering
lock could otherwise engage and the
vehicle could no longer be steered.
There is no power assist while the
engine is off. Therefore, you will need to
exert more force to brake and steer the
vehicle.<
Turn on the hazard warning flashers, if
required by national regulations. If the
electrical system has failed, clearly
identify the vehicle being towed, e.g. by
placing a sign or a warning triangle in
the rear window.
Vehicles with manual transmission:
gearshift lever in idling position.
Vehicles with automatic transmission:
selector lever in position N.
Do not exceed a towing speed of
45 mph / 70 km/h, nor a towing
distance of 90 miles/150 km, because
the automatic transmission could other-
wise be damaged.<
Vehicles with sequential manual gear-
box SMG: selector lever in position N.Towing methodsIn some countries, it is not permitted to
tow the vehicle with a tow bar or tow
rope on public roads.
Familiarize yourself with the applicable
towing regulations for the country in
which you are driving.

With a tow bar
The towing vehicle must not be
lighter than the vehicle being
towed; otherwise, vehicle handling can
no longer be controlled.<
The towing eyelets of both vehicles
should be on the same side.
If the tow bar can only be used in a
diagonal position, please note the fol-
lowing:
>Clearance is restricted while you are
driving around corners
>The inclination of the tow bar pro-
duces lateral force.
Only attach the tow bar to the
towing eyelets. Other parts of the
vehicles could otherwise be dam-
aged.<
With a tow ropeWhen the towing vehicle is driving off,
make sure that the tow rope is taut.
Use nylon ropes or straps for tow-
ing because they prevent sudden
jerking movements. Attach the tow rope
only to the towing eyelets. Other parts
of the vehicles could otherwise be
damaged.<
With a tow truckHave the BMW transported by a tow
truck with a lift sling, or on a flatbed.
Never allow passengers to ride in
a towed vehicle for any reason.<
Do not lift the vehicle by the tow-
ing eyelet, nor by parts of the
body or chassis. Otherwise damage
could result. Do not tow-start vehicles with
automatic transmissions. Jump-
starting, refer to page 147.<
Only tow-start vehicles with catalytic
converters if the engine is cold. It is
better to have the engine jump-started,
refer to page 147.
1. Turn on hazard warning flashers;
comply with national regulations
2. Turn the ignition key to position 2
3. Engage the 3rd gear
4. Have the vehicle towed with the
clutch pedal completely depressed
and then slowly release the clutch
pedal. After the engine has started,
immediately depress the clutch pedal
again completely
5. Pull over at a suitable location,
remove the tow bar or tow rope, and
turn on the hazard warning flashers
6. Have the vehicle checked.
Vehicles with sequential manual gear-
box SMG:
>Have the vehicle towed with the
selector lever in position N
>Select sequential mode. The correct
gear will automatically be selected
and engaged.
