Sitting safely
The ideal sitting position can make a vital con-
tribution to relaxed, fatigue-free driving. In con-
junction with the safety belts, the head
restraints and the airbags, the seated position
has a major influence on your safety in the event
of an accident. To ensure that the safety sys-
tems operate with optimal efficiency, we
strongly urge you to observe the instructions
contained in the following section.
For additional information on transporting chil-
dren safely, refer to page48.
Airbags
Always maintain an adequate distance
between yourself and the airbags. Always
grip the steering wheel on the rim, with your
hands in the 3 o'clock and 9 o'clock positions,
to minimize the risk of injury to the hands or
arms in the event of the airbag being triggered
off. No one and nothing should come between
the airbags and the seat occupant.
Do not use the cover of the front airbag on the
passenger side as a storage area. Make sure
that the passenger is sitting correctly, e.g.,
keeping his or her feet or legs in the footwell
and not on the dashboard; otherwise, leg inju-
ries can occur if the front airbag deploys.
Make sure that passengers do not lean their
heads against the side airbag; otherwise, seri-
ous injuries could result if the airbag suddenly
deployed.<
Even if you follow all the instructions, injuries
resulting from contact with airbags cannot be
fully excluded, depending on the circum-
stances. The ignition and inflation noise may
provoke a mild hearing loss in extremely sensi-
tive individuals. This effect is usually only tem-
porary.
For airbag locations and additional information
on airbags, refer to page85.
Safety belt
Before every drive, make sure that all occupants
wear their safety belts. Airbags complement the
safety belt as an additional safety device, but
they do not represent a substitute.
Your vehicle has two seats, each of which is
equipped with a safety belt.
Never allow more than one person to
wear a single safety belt. Never allow
infants or small children to ride in a passenger's
lap. Make sure that the belt in the lap area sits
low across the hips and does not press against
the abdomen.
The safety belt must not rest against the throat,
run across sharp edges, pass over hard or frag-
ile objects or be pinched. Fasten the safety belt
so that it sits as snugly as possible against the
lap and shoulder without being twisted. Other-
wise, the belt could slide over your hips and
injure your abdomen in the event of a frontal
collision.
Avoid wearing bulky clothing and regularly pull
the belt in the upper-body area taut; otherwise,
its restraining effect could be impaired.<
Safety belts, refer to page44.
Seats
Note before adjusting
Never attempt to adjust your seat while
the vehicle is moving. The seat could
respond with unexpected movement, and the
ensuing loss of vehicle control could lead to an
accident.
On the passenger seat as well, do not incline
the backrest too far to the rear while the vehicle
is being driven; otherwise, there is a danger in
the event of an accident of sliding under the
safety belt, eliminating the protection normally
provided by the belt.<
Note the information on safety belt damage
on page 45.

Automatic heating
Depending on the outside temperature, both
exterior mirrors are heated automatically when
the engine is running or the ignition is
switched on.
Passenger-side mirror tilt function –
automatic curb monitor*
Activating
1.Push the switch to the position for the
driver's side mirror, arrow 1.
2.Engage reverse gear or move the selector
lever to position R.
The glass of the mirror on the passenger
side tilts slightly down. This allows the
driver to see the area immediately adjacent
to the vehicle, e.g., a curb, when backing
into a parking space.
Deactivating
Push the switch to the position for the passen-
ger-side mirror, arrow 2.
Interior rearview mirror
Turn the knob to reduce glare from the head-
lamps of cars behind you when driving
at night.
Interior and exterior mirrors, automatic
dimming feature*
The automatic dimming feature of the interior
and exterior mirrors
* is controlled by two photo
cells in the interior rearview mirror. One photo
cell is in the mirror frame, see arrow; the other is
on the back of the mirror.
In order to ensure that the system functions
correctly, keep the photo cells clean, do not
cover the area between the interior rearview
mirror and windshield, and do not affix adhesive
labels or stickers of any kind to the windshield
directly in front of the mirror.
Steering wheel
Adjustments
Do not adjust the steering wheel position
while the car is in motion; otherwise, there
is a risk of accident due to an unexpected
movement.<
1.Fold the lever down.
2.Move the steering wheel to the preferred
height and angle to suit your seated
position.

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-
