Indicator and warning lamps
The concept
Indicator and warning lamps and their combina-
tions are displayed in the display region1 and in
the display2. To better differentiate between
malfunctions, different symbols can be shown
on the display2.
Some lights in the display region1 are tested
for proper function by briefly lighting up during
starting of the engine or when the ignition is
switched on.
Acknowledging active functions
The following indicator lamps in the display
region1 indicate that the associated functions
are activated:
What to do in case of a malfunction
All warning lamps and indicator lamps not yet
listed are also accompanied by text messages
on the Control Display. These may contain
more information as to the cause of a malfunc-
tion and instructions on what to do.
Sometimes, warning lamps are also accompa-
nied by supplemental text messages on the
Control Display that are shown immediately.
Text messages that do not appear immediately
are stored and can be displayed subsequently.
For further information on displaying these
messages later, refer to Check Control on

3 Start engine
Starting engine
Do not run the engine in closed rooms, as
otherwise the inhaling of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattended vehicle with the engine running, as such a vehicle represents a
potential safety hazard.
To prevent the vehicle from rolling, always
select neutral position or position N and apply
the handbrake before leaving the vehicle with
the engine running.<
When starting the engine, do not press the
accelerator pedal.
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive immediately at a moder-
ate engine speed.
Special starting conditions
Press the accelerator pedal halfway down when
starting if
>the engine fails to start on the first attempt,
for instance, if it is very hot or cold
>the engine is started at very low tempera-
tures, below approx. 57/–156, at high
altitudes, over approx. 3,300 ft/1,000 m.
Avoid frequent starting in quick succes-
sion or repeated start attempts in which
the engine does not start. Otherwise, the fuel is
not burned or inadequately burned and there is
a danger of overheating and damaging the cat-
alytic converter.<
Manual transmission
1.Apply the handbrake.
2.Gearshift lever in neutral position.
3.Press the clutch pedal.
If the clutch pedal is not depressed,
the engine will not start.<
4.Start the engine.
Do not end the starting procedure too early,
however after approx. 20 seconds at the lat-
est. Release the ignition key immediately as
soon as the engine starts.

SMG Sequential manual transmission
and automatic transmission
Your BMW is equipped with the convenience
starting feature. It is sufficient to turn the igni-
tion key into position 3 for only a short time and
then release it again. The system responds by
automatically engaging the starter for a certain
period and allowing it to run until the engine
starts, after which it then disengages automati-
cally.
SMG Sequential manual transmission
1.Press the brake pedal.
2.Place selector lever in position N.
3.Start the engine.
If the engine does not start, shift back to
the last gear selected, refer to Instrument
cluster display, and then shift into position N.<
Automatic transmission
1.Press the brake pedal.
2.Place selector lever in position P or N.
3.Start the engine.
Switching off engine
Do not remove the ignition key while the
vehicle is rolling, as otherwise the steer-
ing wheel lock will immobilize the steering.
When leaving the vehicle, remove the ignition
key and lock the steering. When parking on a
downhill incline, apply the handbrake, as other-
wise the vehicle could roll away.<
Manual transmission
1.Turn the ignition key to position 1 or 0.
2.Shift into first gear or reverse.
SMG Sequential manual transmission
1.Engage a driving position.
2.Turn the ignition key to position 1 or 0.
A signal sounds if the transmission is in
Neutral when the engine is switched off.
Automatic transmission
1.Engage selector lever position P.
2.Turn the ignition key to position 1 or 0.
Handbrake
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.
Indicator lamp
The indicator lamp lights up, and an
acoustic signal also sounds when start-
ing off. The handbrake is applied.
Indicator lamp for Canadian models.
Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If it becomes necessary under special cir-
cumstances to use the handbrake while
driving, it must not be pulled too sharply. In
doing so, continuously press the button of the
handbrake lever. Strong application of the
handbrake can lead to overbraking of the rear
axle and associated 'fishtailing' of the vehicle
rear end.
The brake lamps do not light up when the hand-
brake is applied.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the hand-

Shiftlock
Press the brake pedal before shifting out of N;
the shift command will not be executed unless
the brake is applied.
R Reverse
Select only when the vehicle is stationary.
Sequential mode
After every engine start, as soon as the selector
lever is pushed to the right and the brake pedal
is pressed, the Sequential mode is activated.
You can shift up and down using the shifting
paddles or the selector lever. You do not need
to remove your foot from the accelerator to do
so.
It is also possible to start off in second gear, e. g.
in slippery conditions.
D Drive mode
In the Drive mode, all forward gears are shifted
automatically.
Shifting from Sequential mode to Drive mode:
press selector lever to the right toward D.
Kick-down:
For rapid acceleration, e. g. when passing, press
the accelerator pedal as far down as it will go.
You achieve maximum acceleration.
To switch back into the Sequential mode: press
selector lever to the right again toward D or shift
using the shifting paddles or the selector lever.
Start off quickly on slopes. Do not hold
the vehicle on a hill by pressing the accel-
erator, but apply the handbrake instead. Other-
wise overheating can occur in the transmission
region.<
Gear changes
Using selector lever
>To upshift, pull the selector lever back.
>To downshift, push the selector lever for-
ward.
Using shift paddles on steering wheel
>To upshift, pull one of the shift paddles.
>To downshift, press.
In the following situations, the SMG in Sequen-
tial mode assists you:
>Upshifts and downshifts are executed only
when they will result in a plausible combina-
tion of engine and vehicle speed; thus, for
example, a downshift that would cause the
engine to overrev will not be executed by
the system.
>When the vehicle is stationary, the trans-
mission automatically downshifts into first
gear.
>Shortly before dropping below a gear-
dependent minimum speed, the transmis-
sion downshifts automatically even without
your intervention.
Dynamic Driving Control
The Dynamic Driving Control makes it possible
for your BMW to react in an even more perfor-
mance-oriented manner at the push of a button:
>The engine responds more spontaneously
to accelerator pedal movements.
>Gearshifts are faster.
>The engine speed range is used optimally in
the Drive mode.
>Cruise control

The system requests that you
intervene by braking or with an
evasive maneuver. The display 2
flashes red and a signal sounds.
The active cruise control cannot
automatically restore the distance to the vehicle
driving ahead. You will find more detailed infor-
mation on page. You will find more detailed
information on page64.

Desired speed, store and increase
Press the lever forward 1 at a driving speed of
more than approx. 20 mph/30 km/h:
The system applies and stores your current
speed as a desired speed. This speed is indi-
cated on the speedometer and displayed briefly
in the instrument cluster.
Subsequently pressing forward increases the
desired speed to the next multiple of 5 mph/
10 km/h. Each time the lever is pressed forward
again, the desired speed is increased by
another 5 mph/10 km/h until a maximum of
110 mph/180 km/h is reached. The speed then
displayed is stored and achieved, provided that
the road is clear.
If the display ACC --- mph/km/h briefly
appears in the instrument cluster, it might
be that conditions necessary for operation are
not currently being met.
To call up Check Control messages, refer to
page67.<
Desired speed, store and decrease
Pull back the lever 2:
The current driving speed is rounded off to the
next multiple of 5 mph/10 km/h, displayed and
stored.
Each time the lever is pulled back again, the
desired speed is decreased by another 5 mph/
10 km/h until the minimum speed of 20 mph/
30 km/h is reached. The speed then displayed
is stored and achieved, provided that the road is
clear.
Deactivate system
Press the lever up or down while the system is
active 3. The displays in the instrument cluster
disappear. You can use the system again as
required.
In addition, the system is deactivated automati-
cally:
>When you apply pressure to the brake pedal
>When you select the automatic transmis-
sion's/SMG's neutral position N
>When the manual transmission is shifted
into neutral
>When you deactivate the DSC Dynamic
Stability Control
>When you actuate the handbrake during
driving
>When the system reduces the speed to
below 20 mph/30 km/h due to a traffic situ-
ation
The system deactivates automatically
when the speed is set to below 20 mph/
30 km/h. An acoustic signal sounds and a mes-
sage appears on the Control Display. The active
intervention of the driver is required.<
When you switch off the ignition, the stored
desired speed is deleted.
Resume stored desired speed and
distance setting
Press button 4 when the system is deactivated.

Portable phone in the vehicle
BMW discourages the use of mobile
communications devices, e. g. portable
phones, inside the vehicle without a direct con-
nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communication
device can influence one another. In addition,
there is no assurance that the radiation which
results from transmission will be dissipated
from the vehicle interior.<
Interior and exterior mirrors, automatic
dimming feature*
This feature is controlled by two photocells in
the inside rearview mirror. One is integrated into
the glass of the mirror, while the other is located
at an offset position on the rear of the mirror
housing.
For trouble-free operation, keep the photocells
clean and do not cover the area between the
interior rearview mirror and the windshield. Do
not attach stickers of any kind to the windshield
in front of the mirror, either.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between the tires and
the road surface, ultimately undermining your
ability to steer and brake the vehicle.<
The risk of hydroplaning increases as the tread
depth of the tires decreases, refer also to Mini-
mum tire tread on page173.
Driving through water
Do not drive through water on the road if it
is deeper than 1 ft/30 cm, and then only at
walking speed at the most. Otherwise, the vehi-
cle's engine, the electrical systems and the
transmission may be damaged.<
Using handbrake on inclines
On inclines, do not hold the vehicle with
the clutch; use the handbrake. Otherwise
greater clutch wear will result.<
SMG Sequential manual transmission
Start off quickly on slopes. Do not hold
the vehicle on a hill by pressing the accel-
erator, but apply the handbrake instead. Other-
wise overheating can occur in the transmission
region.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. In situations that require it, it is best to
brake with full force. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.

Malfunctions
Brake fluid
The warning lamp lights up in spite of
the handbrake being released; a mes-
sage appears on the Control Display:
Stop immediately.
The brake fluid in the reservoir has fallen to
below the minimum level. At the same time, a
considerably longer brake pedal travel may be
noticeable. Have the system thoroughly
checked.

When you continue driving, an increased
brake pedal path can be necessary, and
significantly longer braking distances might be
required. Please adapt your driving style
accordingly.<
Brake pads
The warning lamp lights up in spite of
the handbrake being released; a mes-
sage appears on the Control Display:
The brake pads have reached their minimum
pad thickness. Have brake pads replaced
immediately.

malfunction on Canadian models.
For your own safety: use only brake pads
that BMW has approved for the corre-
sponding vehicle model. As BMW cannot
assess the suitability of other brake pads for
use on your vehicle, we are unable to assume
continued responsibility for the vehicle's oper-
ating safety if non-approved pads are
installed.<

1.Insert screwdriver into the slot and press to
the right, refer to arrows. This releases the
lamp.
2.Remove the lamp and replace the bulb.
Backup lamps
In the event of a malfunction, please go to your
BMW center or a workshop that works accord-
ing to BMW repair procedures with correspond-
ingly trained personnel.
LEDs light-emitting diodes
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers, and never
stare directly into the unfiltered light for
several hours, as this could result in irritation of
the retina.<
Changing wheels
Safety precautions in the event of a flat
tire or wheel change: Park the vehicle as
far as possible from passing traffic and on solid
ground. Switch on the hazard warning flashers.
Lock the steering wheel in straight-ahead set-
ting of the wheels. Apply the handbrake and
engage first gear, reverse gear or selector lever
position P.
Have all vehicle occupants get out of the vehicle
and ensure that they remain outside the imme-
diate area in a safe place, such as behind a guardrail.
If a warning triangle or portable hazard warning
lamp is required, set it up on the roadside at an
appropriate distance from the rear of the vehi-
cle. Comply with all safety guidelines and regu-
lations.
Change the wheel only on a level, firm surface
which is not slippery. The vehicle or the jack
could slip to the side if you attempt to raise the
vehicle on a soft or slippery surface such as
snow, ice, tiles, etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar object as a
support base for the jack, as this would prevent
it from extending to its full support height and
reduce its load-carrying capacity.
To avoid serious or fatal injury: never lie under
the vehicle, and never start the engine while it is
supported by the jack.<
What you will need
To avoid rattling noises later on, note the posi-
tions of the tools before removing them, then
return them to their initial positions after com-
pleting work.
