Indicator and warning lamps
The concept
Indicator and warning lamps and their combina-
tions appear in the indicator area1 and in the
display2. For better differentiation of malfunc-
tions, different symbols can appear in the dis-
play 2.
Some lamps in the indicator area1 are checked
for proper operation when the engine is started
or the ignition is switched on and light up briefly
in the process.
Confirmation of active functions
The following indicator lamps in the indicator
area1 indicate that certain functions are active:
Required action in case of a
malfunction
All warning lamps and indicator lamps not pre-
viously listed are also accompanied by text
messages at the bottom of the Control Display.
These may contain detailed information on the
cause of a malfunction and the corresponding
action required.
Sometimes warning lamps are also accompa-
nied by additional text messages on the Control
Display which are displayed immediately. Text
messages which do not appear immediately are
stored and can be displayed at a later time. For
details on displaying these messages later,
refer to Check Control on page71. Turn signals60

Everything under control
Odometer, outside
temperature display, clock
When the ignition is off you can briefly activate
the time, outside temperature and odometer
displays by pressing the knob3 at the lower left
of the instrument cluster.
1 Outside temperature display, clock,
date
The outside temperature and the time are dis-
played from ignition key position 1 onwards.
To call up the date:
Press the CHECK button on the turn signal
lever, refer to page74.
Setting time and date, refer to page78.
You can set the measurement unit 7 or 6 on
the Control Display, refer to Measurement units
on page77.
Ice warning
A signal sounds when the outside temperature
falls to roughly +37.57/+36; this is accompa-
nied by a message.
Please bear in mind that the ice warning
does nothing to alter the fact that black
ice may be present on roads at temperatures
higher than +37.57/+36, e.g. on bridges and
shaded roads.<
2 Odometer and trip odometer
To reset the trip odometer to zero:
Press button3 in the instrument cluster.
Tachometer
The white-striped advance warning field,
arrow1, changes depending on the engine
temperature. The segments disappear in
sequence as the engine warms to its normal
operating temperature.
Avoid allowing the engine speed to rise as far as
the advance warning field whenever possible.
Engine speeds in the red warning field, arrow2,
must absolutely be avoided.
In this range, the fuel supply is interrupted to
protect the engine.

Malfunction in the driving-stability
control systems
The brake system warning lamp lights
up in red, appearing together with the
indicator lamps for ABS and DSC. A
message appears on the Control Dis-
play. The driving-stability control sys-
tems have failed. Conventional braking
efficiency remains available without
limitations.
While you may continue, you should remember
to proceed cautiously and drive defensively
while avoiding full brake applications.
Have the system checked as soon as possible.

malfunction on Canadian models.
The DSC indicator lamp lights up. A
message appears on the Control Dis-
play. A malfunction has occurred in
DSC and DTC.
The stability maintenance functions are no
longer available. The vehicle remains opera-
tional.
Have the system checked as soon as possible.
The warning lamp for the brake system
lights up in yellow. A message appears

Active roll stabilization*
The concept
Active roll stabilization minimizes body roll and
optimizes vehicle stability during cornering and
evasive maneuvers.
Dynamic stabilizers at the front and rear axles
form the basis for active roll stabilization. Sus-
pension compliance adapts to suit driving con-
ditions, varying from performance-oriented
during cornering to smooth and comfort-ori-
ented when the vehicle is proceeding in a
straight line. During vehicle operation, the sys-
tem 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 and a mes-
sage appears on the Control Display.
There is a malfunction in the system.
Have the system checked as soon as possible.
If there is a malfunction in the system,
please remember to adapt your speed
accordingly, especially 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
appears on the Control Display, stop and switch
off the engine as soon as possible. In this case
the oil level in the reservoir may have dropped
below the minimum, possibly owing to a leak in
the hydraulic system. Do not continue driving.

Report of a flat tire
The warning lamp lights up in red. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
1.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden brak-
ing and steering maneuvers. Do not exceed
a vehicle speed of 50 mph/80 km/h.
If the vehicle is not, as provided at the
factory, equipped with run-flat tires,
refer to page172, stop driving. Continued
driving after a flat tire can result in serious
accidents.<
2.Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized.<
3.In case of a complete loss of the tire inflation
pressure or obvious tire damage, you can
estimate the possible driving distance for
continued driving base on the following ref-
erence values:
>With low load:
1 to 2 persons without luggage:
approx. 155 miles/250 km.
>With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 94 miles/150 km.
>With full load:
4 persons, luggage compartment full:
approx. 30 miles/50 km.
Drive reservedly and do not exceed
a speed of 50 mph/80 km/h. In the
event of pressure loss, vehicle handling
changes. This includes reduced tracking
stability in braking, extended braking dis-
tance and altered natural steering charac-
teristics.
If unusual vibrations occur while the vehicle
is being driven, this can indicate final failure
of the damaged tire. Reduce speed and stop as soon as possible. Do not continue
driving. Contact your BMW center.<
Malfunction
The warning lamp lights up in yellow. A
message appears on the Control Dis-
play. The Flat Tire Monitor has a mal-
function or has failed. Have the system checked
as soon as possible.
Active steering*
The concept
The active steering is a system that actively var-
ies the steering angle of the front wheels in rela-
tion to the steering wheel movements.
A t l o w s p e e d , e . g . i n a t o w n o r w h e n p a r k i n g , t h e
steering angle of the wheels is reinforced, i.e.
the steering becomes very direct.
In the higher speed range, on the other hand,
the steering angle is reduced more and more.
This improves the handling capability of your
BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stability-pro-
moting intervention is deactivated when DSC is
switched off, refer to page82.
Malfunction
The warning lamp lights up. The active
steering is no longer operational. At low
speed, larger steering wheel move-
ments are required, while the vehicle reacts
more sensitively to steering wheel movements
in the higher road-speed range. Have the sys-
tem checked.
If the warning lamp lights up during the first
engine starting following a power supply inter-
ruption, the system must be activated by being
initialized.

Lamps
92 The low beams remain on independent of
the ambient lighting conditions when you
switch on the fog lamps.
With the daytime driving lamps activated, the
low beams are always switched on in this switch
position with the ignition key in position 2.<
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the system
cannot detect fog. To avoid safety risks, you
should always switch on the lamps manually
under these conditions.<
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables better illumination
of the road surface. Depending on the steering
angle and other assumptions, the light from the
headlamp follows the course of the road.
Activating Adaptive Head Light
In switch position3 the Adaptive Head Light is
active and the automatic headlamp control is
switched on.
To avoid blinding oncoming traffic, the Adaptive
Head Light
>is not active when driving in reverse
>i s o n l y a c t i v e t o w a r d p a s s e n g e r ' s s i d e w h e n

lamp control flashes. The Adaptive Head Light
is malfunctioning or has failed. Have the system
checked as soon as possible.
High beams/
roadside parking lamps
1High beams
2Headlamp flasher
3Roadside parking lamps
Roadside parking lamps, left or right*
You also enjoy the option of lighting up just one
side of your vehicle when parking. When using
this function, comply with national regulations:
With the ignition switched off, press the lever in
the desired direction3, past the resistance
point.
The roadside parking lamps drain the bat-
tery. Avoid using for longer periods, as
otherwise it may not be possible to start the
engine.<
Fog lamps
The parking lamps or low beams must
be switched on for the fog lamps to
operate. The green indicator lamp in
the instrument cluster lights up when the fog
lamps are switched on.

Refueling
166
Refueling
Always switch off the engine before refu-
eling. If you do not, fuel cannot be dis-
pensed into the tank and a message on the
Control Display will appear.<
Always observe all applicable precautions
and regulations when handling fuels.
Never carry spare fuel containers in your vehi-
cle. Whether empty or full, these containers can
leak, cause an explosion, and lead to fire in the
event of a collision.<
Fuel filler door
To open and close: briefly press the rear edge of
the fuel filler door.
Manual release
In the event of an electrical malfunction in the
system, you can release the fuel filler door man-
ually:
In the luggage compartment, pull the knob with
the gas pump symbol on the right side panel.
Observe following when refueling
When handling fuels always observe any
safety guidelines posted at the gas sta-
tion.<
Put the fuel filler cap in the bracket attached to
the fuel filler door.
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Lifting the filler nozzle
during refueling
>results in premature pump shutoff
>can lead to reduced efficiency in the fuel-
vapor recovery system
The fuel tank is full when the filler nozzle clicks
off the first time.
Fuel tank capacity
Approx. 18.5 US gallons/70 liters, including the
reserve capacity of approx. 2.1 gallons/8 liters.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, as otherwise engine functions are not
ensured and damage can occur.<
Closing fuel filler cap
Fit the cap and turn it clockwise until you clearly
hear a click.
Close the fuel filler cap carefully after
refueling, continuing 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 an indicator lamp and the mes-
sage Check Gas Cap
* on the Control Display.<

1.Park the vehicle on a level surface with the
engine warm, i.e. after an uninterrupted
drive of at least 6 miles/10 km.
2.Switch off the engine.3.After approx. 5 minutes, pull the dipstick3
out and wipe it off with a clean lint-free
cloth, paper towel, or similar material.
4.Carefully push the dipstick all the way into
the guide tube and pull it out again.
The oil should extend to between the two
marks on the dipstick.
The oil quantity between the centers of the two
marks on the dipstick, refer to arrows, is approx.
1.6 US quarts/1.5 liters.
Do not fill beyond the upper mark on the
dipstick. Excess oil can damage the
engine.<

Under the hood

Topping off engine oil
Wait until the level has dropped to just above
the lower dipstick mark before adding oil. When
it falls to this level, a message also appears on
the Control Display.
Refill the oil within the next 125 miles/
200 km, otherwise engine damage could
result.<
Store oil, grease etc., well out of the reach
of children; always observe all warning
labels on the containers.<
Oil change
Have oil changes carried out only by a BMW
center.
Specified 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 you are unable to obtain BMW High Perfor-
mance Synthetic Oil, you can add small
amounts of another synthetic oil between oil
changes. Use only oils with the API SH specifi-
cation or higher.
Ask your BMW center for details concern-
ing the specific BMW High Performance
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 information.BMW engines are designed to operate
without additives, and their use could
even lead to damage in some cases.<
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 open the cooling system when the
engine is hot. Escaping coolant can cause
burns.<
Coolant consists of water and coolant additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for
suitable additives.
Only use suitable additives, as otherwise
engine damage may result. The additives
present a health hazard.<
Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives.<
Checking coolant level
1.The engine must be at ambient tempera-
ture.

The BMW Maintenance
System
The BMW maintenance system supports the
preservation of the traffic and operating safety
of your BMW. The service schedule also
includes operations related to the vehicle's
comfort and convenience features, such as
replacement of the filters for the inside air. The
ultimate objective is to ensure economical
maintenance by providing the ideal service for
your 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 inestimable value.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
You can set the Control Display to show
remaining times or distances of selected main-
tenance intervals and legally mandated dead-
lines, refer to page70:
>Engine oil
>Brakes, front and rear separately
>Microfilter/activated-charcoal filter
>Brake fluid>Spark plugs
>Vehicle check
>Legally required tests depending on local
regulations
Your vehicle stores this information continu-
ously in the master key while the vehicle is
being driven. After accessing the data stored in
the master key, your BMW Service Advisor can
suggest precisely the right array of service pro-
cedures for your own individual vehicle. You
should therefore give your BMW Service Advi-
sor the key you last used to drive when you take
your vehicle in for service.
Make sure the date in the Control Center
is always set correctly, refer to page78,
as otherwise the effectiveness of CBS Condi-
tion Based Service is not ensured.<
