Seat and mirror memory
*
Adjusting steering wheel
Your BMW center can adjust your
vehicle's systems in such a man-
ner that your personalized settings are
automatically set for the seat and out-
side mirror positions when you unlock
the vehicle with your personal remote
control.<
If you make use of this method of
adjustment, be sure that the foot-
well behind the driver's seat is unob-
structed before unlocking the vehicle.
If you fail to do so, persons or objects
could be injured or damaged if the seat
should move backward.<
Passenger side exterior mirror tilt
function(automatic curb monitor)
1 Move the mirror selector switch 1 to
the "driver's mirror" position.
2 When the selector lever is placed in
"Reverse," the passenger-side mirror
tilts downward. This allows the driver
to see the area directly adjacent to
the vehicle during parking (curbs,
etc.).
You can deactivate this automatic fea-
ture: Set the mirror selection switch to
the "passenger side" position.463de043
1 Push the locking lever downward.
2 Adjust the steering wheel (fore/aft
and up/down) to the desired position.
3 Pull the lever back in to clamp the
steering wheel in the new position.
Do not adjust the steering wheel
while the vehicle is moving. If you
do so, there is a risk of accident from
unexpected movement.<460de073

AirbagsIndicator lamp
The indicator lamp displays the
operational status of the airbag
system when the ignition key is
in position 1 and higher.
System operational:
>The indicator lamp comes on briefly
then goes out.
System malfunction:
>The indicator lamp fails to come on.
>The indicator lamp comes on briefly
before going out, and then lights up
again.
If there is a system malfunction, there is
a risk that the airbags will not be trig-
gered within their normal response
range, even if the level of impact would
normally have triggered them.
Have your BMW center inspect and
repair the system immediately.
The airbag indicator lamp also
comes on if the safety belt ten-
sioners have been triggered.<
For your own safety, please com-
ply with the following precautions
concerning airbags. If you do not, their
protective function may be impaired
and your personal safety endangered.
The following information pertains to all
occupants:
The airbags are supplemental restraint
devices designed to provide extra pro-
tection; they are not a substitute for
safety belts. Wear your safety belt at all
times. The airbags will not be triggered
in the event of a minor accident, a vehi-
cle roll-over, or collisions from the rear.
In these instances, the safety belt offers
the best protection.
Airbags are located under the cover
panels in the steering wheel, in the in-
strument panel, in the side trim panels
in the front and rear
*, in the roof panels,
and in the sides of the inside roof lining.
Select a seat position that is comfort-
able and allows the greatest possible
distance from each of the applicable air-
bags. Hold the steering wheel at the rim
(hands at the "9 o'clock and 3 o'clock"
positions) in order to avoid injuries to
your hands or arms if the airbag is trig-
gered.
Never allow any objects to obstruct the
area between the airbag and an occu-
pant.
Do not use the cover panel above the
front passenger airbag as a storage
area.
Never tape the airbag cover panels,
cover them over or alter them in any
other way.
Never install a rear-facing child restraint
device on the front passenger seat. Chil-
dren under 13 years of age and children
who are smaller than 5 feet (150 cm),
should only travel in the rear seat.
If your vehicle is equipped with side air-
bags in the rear, be sure that child seats
are installed correctly and with the
greatest possible distance from the side
trim panels. Do not allow children to
lean out of the child's seat in the direc-
tion of the side trim panels. Otherwise,
serious injuries could occur if the airbag
is triggered.
At all times, occupants should sit up-
right and be properly restrained (infants
and small children in appropriate child
restraint systems; larger children and
adults using the safety belts). Never let
an occupant's head rest near or on a
side airbag because the inflating airbag
could cause a serious or fatal injury.
Please note that the word "Airbag" im-
printed on the door trim panel indicates
the airbag's location.

0 Steering lock engaged The key can only be inserted or re-
moved in this position.
After removing the key, turn the steer-
ing wheel slightly to the left or right until
the lock engages.
If the key is not removed, an acoustic
signal is sounded after the driver's door
has been opened.
Vehicles with automatic transmis-
sion:
Do not move the selector lever from the
"Park" position until the engine is run-
ning (ignition key at position 2).
In order to turn the key back to position
0 or to remove it, move the selector
lever into position "Park" first (Inter-
lock).<460de022
1 Steering lock disengaged Turning the steering wheel slightly to
the right or left often makes it easier to
turn the key from 0 to 1.
Individual electrical devices are ready
for operation.2 Ignition onAll electrical equipment and accesso-
ries are available for use.3 Starting the engine
Vehicles with manual transmis-
sion: Depress the clutch when
starting the vehicle. A lockout prevents
the engine from starting if the clutch is
not depressed.c
Before starting>Engage the parking brake.
>Be sure that the shift lever is in "Neu-
tral" (or "Park" if the vehicle is equipped
with an automatic transmission).
>Manual transmission: Depress the
clutch pedal.
>Automatic transmission: Depress the
footbrake.
Do not run the engine in enclosed
areas. The exhaust gases contain
carbon monoxide, an odorless and col-
orless, but highly toxic gas. Breathing
the exhaust gases poses an extreme
health risk, and can lead to uncon-
sciousness and death.
Do not leave the car unattended with
the engine running. An unattended vehi-
cle with a running engine represents a
potential safety hazard.<
>Start the engine. Do not press the
accelerator pedal.
Do not actuate the starter for too
short a time, but not turn it for more
than approx. 20 seconds. Release the
ignition key immediately when the
engine starts.
Do not allow the engine to warm up by
leaving it running while the vehicle remains
stationary. Instead, begin driving immedi-
ately at a moderate engine speed.<

attempt (if it is very hot or cold, for in-
stance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold start at extremely low tempera-
tures, from approx. + 5 7 (Ð 15 6)
and at elevations above 3,300 feet
(1,000 meters):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds)
>Press the accelerator pedal halfway
down while engaging the starter.Turn the ignition key to position 1 or 0.
Do not remove the ignition key
while the vehicle is still moving.
If you did so, the steering lock would
engage when the steering wheel is
turned.
When you leave the vehicle, always re-
move the ignition key and engage the
steering lock.
Vehicles with manual transmission:
Always engage the parking brake when
parking on slopes and inclined sur-
faces. Placing the lever in 1st gear or
reverse may not provide adequate
resistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park."<

Dynamic Stability Control (DSC) The conceptDSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, the system recog-
nizes unstable vehicle conditions (un-
dersteering or oversteering, for example)
and holds the vehicle on a sure course
by intervening via the engine and by
braking intervention at the individual
wheels.
The system activates automatically each
time you start the engine.462us284
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to pages 21 and 22.
Indicator lamp flashes:
The system is actively regulating drive
torque in response to monitored vehicle
operating conditions.
If the indicator lamp fails to go out after
the engine is started, or comes on dur-
ing the course of normal vehicle opera-
tion:
If the system was not switched off,
there is a system malfunction. The vehi-
cle remains operational, but without
DSC. Please consult your BMW center
for repairs.
To deactivate the systemPress the button. The indicator lamp
flashes.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.
When the DSC is deactivated, you are
operating the vehicle in the conven-
tional drive mode.
In exceptional instances, it is effective
to deactivate the system:
>when rocking the vehicle or starting
off in deep snow or on loose surfaces
>or when driving with snow chains.
Refer also to page 110.To reactivate the systemPress the button again; the indicator
lamp goes out.
The laws of physics cannot be re-
pealed, even with DSC. Any con-
sequences arising from traction loss
due to excessive vehicle speed remain
the responsibility of the driver. For this
reason, do not take risks by using the
additional safety margin provided by
the system as an excuse.<
For additional details concerning DSC,
please refer to the chapter describing
"Advanced technology" on page 163.

Antilock Brake System (ABS)The concept ABS enhances active safety by helping
to prevent the wheels from locking un-
der braking. This is because locked
wheels are dangerous. When the front
wheels slide, the driver loses steering
control over the vehicle. Traction loss at
the rear wheels can cause the rear end
to break into an uncontrolled skid.
ABS is designed to meet two essential
requirements during every brake appli-
cation:
>To help provide vehicle stability
>To help maintain steering control and
maneuverability Ð on all types of road
surfaces (asphalt, concrete, mud, wet,
snow, ice).
The system can achieve the shortest
braking distances possible under most
conditions (on straight-aways and in
curves, on asphalt, ice, wet road sur-
faces, etc.).
Braking with ABSThe system becomes operative once
the vehicle exceeds a speed of approx.
6 mph (10 km/h). Below approx. 3 mph
(6 km/h), it is once again deactivated.
This means that the wheels can lock in
the final phase of a panic stop Ð a factor
of no significance in actual use.
If you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply maxi-
mum brake pressure ("panic stop").
Since the vehicle maintains steering re-
sponsiveness, you can avoid possible
obstacles with a minimum of steering
effort, despite the full brake application.
The ABS system closed-loop control
circuit cycles in fractions of a second.
A pulsation at the brake pedal indicates
to the driver that ABS is active, that is,
that the vehicle is within its maximum
braking range. In addition, a pulsation Ð
a result of the control function cycles Ð
indicates to the driver that vehicle
speed should be reduced to adapt to
road surface conditions when there is
reduced traction and grip between tires
and road surface (slippery road sur-
face).
On road surfaces that have a loose sur-
face layer on a firm base with good
traction (on gravel or snow, for exam-ple), or when snow chains are mounted,
braking distances may be longer than
with locked wheels. However, ABS
continues to provide enhanced vehicle
stability and steering response under
these conditions.
Information for your safetyNot even ABS can suspend the laws of
physics. ABS cannot prevent the con-
sequences of brake applications with
inadequate clearances for safety be-
tween vehicles, when exceeding the
speed limit in curves, or the risks in-
volved when aquaplaning occurs. Re-
sponsibility for these types of situations
remains in the hands (and at the feet) of
the driver. You should never allow the
added safety of ABS to lull you into a
false sense of security, or mislead you
into taking increased risks that could af-
fect your own safety and that of others.
Do not make any modifications to
the ABS system.
Service procedures on ABS are to be
performed by authorized technicians
only.<

Disc brakesDisc brakes furnish optimum decelera-
tion and braking control and greater
fade resistance under heavy use.
When the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, and in oper-
ating conditions where brake applica-
tions are less frequent, there is an
increased tendency for corrosion of the
rotors and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure that must
be exerted by the pads to clean the
rotors by brake applications is not
reached.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
For your own safety: Use only
brake pads that BMW has ap-
proved for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
Driving notesWhen driving in wet conditions and in
heavy rain, it is effective to apply light
pressure to the brakes every few miles
or kilometers. Be aware of traffic condi-
tions to ensure that this maneuver does
not endanger other road users. The
heat that is generated by the brake ap-
plications helps to dry the brake pads
and rotors.
Maximum braking force is obtained
while the wheels are not locked, but
rather when they are still barely turning
immediately prior to locking. ABS main-
tains this state automatically. If the ABS
fails, you should revert to the staggered
braking technique described above on
page 110.
Long or steep mountain descents do
not necessarily lead to reduced braking
efficiency if you drive downhill with the
transmission in a gear that allows mini-
mal brake applications (or, with an au-
tomatic transmission, in an appropriate
lower range).
You can further increase the engine's
braking effect by selecting a lower gear,
downshifting as far as first gear or plac-
ing the selector lever in position 1.Should engine braking prove inade-
quate, you should still avoid extended,
continuous braking. Instead of main-
taining low to moderate pressure over
an extended period of time, you should
decelerate by applying more substantial
pressure to the brake pedal (watch for
following traffic), releasing the pedal,
and then repeating the application
(staggered braking). The cooling phases
between active braking intervals pre-
vent the brakes from overheating, thus
ensuring that full braking capacity re-
mains available at all times.
Do not coast with the clutch de-
pressed or with the shift lever or
selector lever in neutral. Do not drive
with the engine shut off. The engine
provides no braking effect when the
clutch is depressed or the transmission
is in neutral, and there is no power-
assist for braking or steering when the
engine is not running.
Do not allow floor mats, carpets or any
other objects to protrude into the area
around the brake pedal, the clutch or
the accelerator which could obstruct
their freedom of movement.<
