Indicator and warning lamps
The concept
Indicator and warning lamps can light up in a
variety of combinations and colors.
Some lamps are checked for proper functioning
and thus come on briefly when the engine is
started or the ignition is switched on.
Explanatory text messages
Text messages at the upper edge of the Control
Display explain the meaning of the displayed
indicator and warning lamps.
You can call up more information, e.g., on the
cause of a malfunction and on how to respond,
via Check Control, refer to page73.
In urgent cases, this information will be shown
as soon as the corresponding lamp comes on.

Parking brake
The concept
Your BMW is equipped with an electromechan-
ical parking brake that can be set and released
by using a button.
The parking brake is primarily used to prevent
the vehicle from rolling when it is parked.When the vehicle is stationary, the parking
brake acts on the rear wheels via an electrome-
chanical mechanism. When the vehicle is rolling
or being driven, the parking brake acts on the
disc brakes of the front and rear wheels via the
hydraulic brake system.
Setting the brake
Pull the button. The parking brake is set.
The indicator lamp in the instrument
cluster and the LED on the button light
up red. The parking brake is set.

To set the parking brake, the remote control
does not need to be in the ignition lock.
While driving
In the rare case that the parking brake needs to
be used while driving, pull the button for a
lengthy period:
The vehicle brakes hard while the button is
being pulled.
The indicator lamp in the instrument
cluster lights up red, a sound is issued
and the brake lamps light up.

Cleaning windshield and headlamps*
Pull the lever, arrow 4.
Washer fluid is sprayed onto the windshield and
the wipers are operated for a short time.
When the vehicle lighting system is switched
on, the headlamps are cleaned at regular and
appropriate intervals.
Do not use the washers if there is any
danger that the fluid will freeze on the
windshield. If you do, your vision could be
obscured. Antifreeze should therefore be
added to the fluid, refer to Washer fluid.
Do not use the washers when the washer fluid
reservoir is empty; otherwise, you will damage
the washer pump.<
Windshield washer nozzles
The windshield washer nozzles are heated
automatically while the engine is running or the
ignition is switched on.
Washer fluid
Washer fluid antifreeze is flammable.
Therefore, keep it away from ignition
sources and only store it in the closed original
container that is kept out of reach of children;
otherwise, there is a risk of personal injury.
Comply with the instructions on the con-
tainer.<
Washer fluid filler neck
Only refill washer fluid when the engine is
cool to avoid contact with hot engine
parts. Otherwise, fluid spills constitute a fire
hazard and a risk to personal safety. fluid by the same reservoir.
Fill with water and, if required, with a washer
antifreeze, according to manufacturer's recom-
mendations.
Mix the water and antifreeze before filling
the washer fluid reservoir to make sure
the correct concentration is maintained.<
Capacity
Approx. 6.3 US quarts/6 liters.
Cruise control*
The concept
Cruise control is available for use at speeds of
approx. 20 mph or 30 km/h. The car then stores
and maintains the speed that you specify using
the lever on the steering column. In order to
maintain the specified speed, the system
brakes the vehicle when the engine braking
effect is insufficient on downhill gradients.
Do not use cruise control when driving at
constant speed is prevented by adverse
conditions, e.g., winding roads, dense traffic,
poor visibility or unfavorable road conditions
due to, e.g., snow, rain, ice or loose surfaces.
Otherwise, you could lose control of the vehicle
and cause an accident as a result.<
Manual transmission
You can shift gears while cruise control is acti-
vated. An indicator lamp notifies you that you
should shift gears when you drive for an
extended period at very high or very low engine
speeds, or the system is deactivated.

Maintaining current speed
Tap the lever, arrow 1, or pull it briefly, arrow 2.
The car's current speed is stored and main-
tained. It is displayed on the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking
effect is insufficient on downhill slopes, the sys-
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow1, until the desired
speed is reached.
>Each time the lever is pressed to the resis-
tance point, the desired speed is increased
by approx. 1 mph or 1 km/h.
>Each time the lever is pressed beyond the
resistance point, the desired speed is
increased by up to 5 mph or 10 km/h.
The system stores and maintains the speed.
Accelerating using the lever
Accelerating slightly:
Press the lever to the resistance point, arrow 1,
and hold until the desired speed is reached.Accelerating significantly:
Press the lever beyond the resistance point,
arrow 1, and hold until the desired speed is
reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores and
maintains the speed.
Decreasing speed
Repeatedly pull the lever to the resistance point
or beyond, arrow 2, until the desired speed is
displayed.
>Each time the lever is pulled to the resis-
tance point, the desired speed is decreased
by approx. 1 mph or 1 km/h.
>Each time the lever is pulled beyond the
resistance point, the desired speed is
reduc ed by up to 5 mph o r 10 km/h until the
minimum speed of 20 mph or 30 km/h is
achieved.
The system stores and maintains the speed.
Interrupting the system
Tap the lever upwards or downwards, arrow3.
The displays in the speedometer change color.
In addition, the system is automatically deacti-
vated:
>When you brake the vehicle
>When you switch gears very slowly or shift
to neutral in cars with a manual trans-
mission
>When you engage selector lever position N
in cars with an automatic transmission
>When you engage transmission position N
in 7-gear sport automatic transmissions
with a dual clutch
>When you activate the DTC Dynamic Trac-
tion Control or deactivate DSC
>When DSC or ABS is intervening
Cruise control is not deactivated by depressing
the accelerator pedal. Once the accelerator
pedal is released, the stored speed is achieved
again and maintained.

Technology for driving comfort and safety
78 Loud sound sources outside or inside the car
can drown out the PDC signal. Therefore,
always drive cautiously; otherwise, there is a
risk of personal injury or property damage.<
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
Antilock Brake System ABS
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page114.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake for the
duration of the full braking application.
Dynamic Stability Control DSC
DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. The system also recognizes unstable
driving conditions, for example if the rear of the
car is about to swerve or if momentum is acting
at an angle past the front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through braking actions at the indi-
vidual wheels.The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
s a f e t y m a r g i n a g a i n b y t a k i n g r i s k s , a s t h i s c o u l d
result in an accident.<
Deactivating/activating the DSC OFF
program
The program can be deactivated via Dynamic
Driving Control, refer to DSC OFF.
For better control
The indicator lamp flashes: DSC con-
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.
DTC Dynamic Traction Control
The concept
The DTC system and the TRACTION program
are a variant of the DSC in which forward
momentum is optimized.
The system ensures maximum forward
momentum on special road conditions, e.g.,
unplowed snowy roads, but driving stability is
limited.
It is therefore necessary to drive with appropri-
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving in slush or on uncleared,
snow-covered roads.
>When rocking the vehicle or driving off in
deep snow or on loose surfaces.
>When driving with snow chains.
Deactivating/activating DTC Dynamic
Traction Control
The system and program can be deactivated/
activated via Dynamic Driving Control.

The drive-off assistant enables you to drive off
smoothly on uphill gradients. The parking brake
is not required.
1.Hold the car in place by depressing the
brake.
2.Release the brake and drive off without
delay.
The drive-off assistant holds the car in

able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Servotronic*
The concept
The Servotronic varies the steering force
required to turn the wheels depending on the
speed at which you are driving. When you are
driving at low speeds, power steering provides
more support, i. e. little effort is needed to turn
the wheels. Power steering support lessens as
your speed increases.
The system works automatically.
Malfunction
Malfunctions are displayed via Check Control.
Dynamic brake lamps*
On the left: normal braking.
On the right: sharp braking.
During sharp braking, the brake lamps and the
dynamic brake lamps of your BMW light up.
The dynamic brake lamps are automatically
activated if the turn signal is not flashing.
Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Side airbags in the seat backrests
3Knee airbag
Protective action
Observe the adjustment instructions on
page41 to ensure the best possible per-
sonal protection.<
The front airbags help protect the driver and
passenger by responding to frontal impacts in
which safety belts alone cannot provide ade-
quate restraint. When needed, the side airbags
help provide protection in the event of a side
impact. The relevant side airbag supports the
head and the side upper body area.
The airbags have been designed to not be trig-
gered in every collision situation, e.g., not in
minor accidents or rear-end collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Keep the dashboard and window on the pas-
senger side clear, i.e., do not cover with adhe-
sive labels or coverings, and do not attach hold-
ers such as for navigation instruments and
mobile phones.
Do not attach seat covers, cushions or other
objects to the front seats that are not specifi-
cally approved for seats with integral side air-
bags. Do not hang items of clothing such as
coats or jackets over the backrests.
Do not attempt to remove the airbag retention
system from the vehicle. Do not modify the indi-
