For maximum safety when adjusting the
seating position, please observe the
following:
Never try to adjust your seat while
driving the vehicle. The seat could
respond with an unexpected move-
ment, and the ensuing loss of vehicle
control could lead to an accident.
Be sure that the safety belt remains
firmly against your body at all times. In
the event of a frontal impact, a loose lap
belt could slide over the hips, leading to
abdominal injury. In addition, the safety
belt's restraint effectiveness is reduced
if the belt is worn loosely.
Never ride with the backrest reclined to
an extreme angle (especially important
for the passenger to remember). If you
do so, there is a risk that you will slide
under the safety belt in an accident,
thus reducing the protection provided
by the safety belt.<
Correct sitting postureTo reduce strain on the spinal column,
sit all the way back in the seat and rest
your back fully against the backrest.
The ideal sitting posture is achieved
with your head extending from your
spine in a straight line.
For long-distance driving, you may wish
to increase the backrest tilt-angle
slightly to reduce muscular tension.
You should be able to grasp the
steering wheel at its highest point with
your arms slightly bent.
1 Backward/Forward adjustment
2 Cushion height
3 Backrest angle
Adjust the head restraint manually.
Ensure that the backrest detent is
fully engaged before sliding the
seat to the rear. If the seat is moved
back with the backrest is folded
forward, the detents may not engage
during subsequent attempts to return
the backrest to its upright position.
Both the rear of the backrest and the
upholstery in the rear storage well may
sustain damage as a result. Always
ensure that the backrest is not reclined
to an excessively steep angle when
sliding the seat back: failure to observe
this precaution can result in damage to
both the upholstery in the rear storage
well and to the backrest itself.<

Adjusting the steering wheel
Mirrors
Press the button to move the steering
wheel forward or back to suit your
selected seating 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.<520de118
Exterior mirrors1 Switch for 4-way adjustment
2 Selection switch for changing
between mirrors, switch either all the
way to the left or the right 520de018
You can also adjust the mirrors manu-
ally by pressing against the outer edges
of their lenses.
When estimating the distance
between yourself and other traffic,
bear in mind that the objects reflected
in the mirror are closer than they
appear. This means that estimates of
the distance to following traffic should
not be regarded as precise.

AirbagsSitting correctly with airbags
Comply with the following instruc-
tions for the airbags, otherwise,
the airbags may not be able to provide
their maximum protection, with
resulting risks to personal safety. All
passengers in the vehicle should be
aware of and comply with this informa-
tion:
The airbag is a supplemental restraint
device; it is not a substitute or replace-
ment for your safety belt, which you
should continue to wear at all times.
When adjusting your seat, assume a
comfortable driving posture allowing
comfortable and secure access to all of
the vehicle's controls. Avoid sitting too
close to the steering wheel.
Always hold the steering wheel by the
rim Ð hands in the "9 o'clock" and
"3 o'clock" positions Ð otherwise, your
hands or arms could be injured if the
airbag is triggered.
Never allow any other passengers,
animals or objects to intrude into the
area between the airbag and the driver
or front passenger.
Do not use the cover panel above the
front passenger airbag as a storage
area.
Do not apply adhesive materials to the
cover panels of the airbags, or cover or
modify them in any other way.
Do not use a rear-facing child seat in the
front passenger seat. If you use a child
restraint system, carefully read and
comply with the instructions on page 53.
Be sure that child seats are installed
correctly and with the greatest possible
distance between them and the side
airbag. Do not allow children to lean out
of the child's seat in the direction of the
side trim panels. If they do so, serious
injuries can occur if the airbag is trig-
gered.<
Even when all these guidelines are
observed, there is still a small residual
risk of injury to the face, hands and
arms occurring from airbag deployment
in isolated instances.
The ignition and inflation noise may
cause a mild temporary hearing loss in
extremely sensitive individuals.
You will find the proper airbag safety
precautions on both sun visors and on
the instrument cluster (US models).
For additional information concerning
the airbag system, refer to pages 121
and 148.The illustration shows the correct
seating position for a child in a child
restraint system
* with sufficient
distance between the child and the side
airbag (arrow).

detent can be heard disengaging. If
you encounter any resistance when
turning the key to the right this indi-
cates that the detent is still engaged:
turn the steering wheel slightly to free
the mechanism and turn the key.
The vehicle immobilizer is deacti-
vated

Removing the keyThe key is removed in position 0. Turn
the steering wheel to engage the
steering lock and activate the electronic
vehicle immobilizer.
With a discharged or discon-
nected battery, the steering
column will not be locked or unlocked.
Leaving the key in the ignition uses up a
minimal amount of power. In order to
avoid discharging the battery, remove
the key if the vehicle is to be parked for
an extended period of time.<
If the steering is locked and the
battery discharged or discon-
nected, do not tow the vehicle, as it will
not be possible to turn the steering

Do not allow the engine to run in
enclosed areas. The exhaust
gases contain carbon monoxide, an
odorless and colorless, but highly toxic
gas. Breathing the exhaust gases poses
an extreme health risk, and can lead to
unconsciousness and death.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard.<520de141
>Start the engine (by pressing the start
button) but do not step on the accel-
erator pedal.
Do not press on the starter button
for too short a time, but do not hold
it down for longer than 20 seconds,
either. Do not allow the engine to warm
up by leaving it running while the vehicle
remains stationary. Instead, drive off
immediately at a moderate engine
speed.<
Cold starts at very low temperatures,
from approx. +5 7 (Ð15 6) and at alti-
tudes above 3,300 ft (1,000 meters):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds).
Engine idle speed is controlled by the
electronic engine management system.
A fast idle immediately after starting is
normal and should decrease as the
engine warms up. If the idle does not
return to normal as the engine reaches
normal operating temperature, service
is required.
To prevent the battery from discharg-
ing, always deactivate electrical
devices that are not in use. Switch the
ignition off when the vehicle is not
being driven.
Turn the ignition key to position 1 or 0.
Never remove the ignition key
while the vehicle is rolling. If you
did so, the ignition lock would engage
when the steering wheel is turned.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.
Always engage the parking brake when
parking on hills and inclined surfaces,
as first gear or reverse may not provide
adequate resistance to rolling.<

Parking brake The parking brake is primarily designed
to prevent the vehicle from rolling while
parked. It operates on the rear wheels.To engageThe lock engages automatically when
you lift the lever, and the indicator lamp
in the instrument cluster comes on
when the ignition key is in position 2.
Refer to page 21.To releasePull up slightly on the lever, press the
button and lower the lever.520de024
If, in rare circumstances, it should
be necessary to engage the
parking brake while the vehicle is in
motion, do not pull hard on the lever.
Keep your thumb pressed against the
release button while carefully pulling
the lever up to apply moderate pres-
sure.
Excessive pressure can lead to over-
braking and loss of traction (fishtailing)
at the rear axle.
The brake lamps do not come on when
the parking brake is engaged.
Always engage the parking brake when
parking on hills and inclined surfaces,
as selecting first gear or reverse may
not provide adequate resistance to
rolling.<
To avoid corrosion and one-sided
braking, apply the parking brake lightly
from time to time when coasting to a
standstill (at a traffic signal, for
instance), provided that it is safe to do
so.

The conceptDSC maintains vehicle stability even in
critical driving situations.
DSC maintains optimal, predictable re-
sponse while maximizing traction when
you accelerate from a standing start or
speed up while already underway. The
system recognizes any tendency for the
vehicle to assume an instable attitude
such as oversteer and understeer, and
counteracts this tendency with a com-
bination of graduated reductions in en-
gine torque and braking intervention at
individually selected wheels. DSC pro-
vides optimal stability Ð within the limits
defined by the laws of physics.
The system automatically assumes
operational status each time the en-
gine is started.
Indicator lamp
The indicator lamp in the in-
strument cluster goes out
shortly after you switch on the
ignition. Refer to page 22.
The indicator lamp flashes:
The system is actively regulating drive
torque.
The indicator lamp does not go out
after the engine is started, or if it comes
on during normal driving and stays on:
There is a system malfunction or the
system was deactivated with the button.
You can continue to drive the vehicle
normally, but without DSC.
Please respond to any suspected de-
fects by referring the problem to your
BMW center.
To deactivate the systemPress the button, the indicator lamp
comes on and stays on.
When the DSC is deactivated, you are
operating the vehicle in the conven-
tional drive mode.
In the following rare circumstances, it
may be effective to deactivate the DSC
for a short period of time:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces.
To maintain vehicle stability,
always drive with the system
switched on when possible.<520de035

Tire Pressure Warning (RDW)The conceptRDW monitors the tire pressure in all
four wheels while driving. The system
provides an alert whenever the inflation
pressure drops significantly in one of
the tires.
For RDW to "learn" the correct tire infla-
tion pressure, check the inflation pres-
sure in all tires, comparing them with
the values in the inflation pressure table
(refer to page 27), and make correc-
tions as necessary. Then activate the
system.
The indicator lamp within the in-
strument cluster flashes to alert
you to substantial pressure loss
in any of the tires.
To activate the system 1 Turn the ignition key to position 2
2 Press the switch long enough for
the indicator lamp in the instrument
cluster to light up red for a few
seconds
3 RDW carries out an automatic
initialization process while you are
driving, and stores this data to aim for
optimal conditions. This one-time
"learning" process lasts at least
10 minutes, after which the RDW is
able to detect and report a flat tire.520de117
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement.
Do not reactivate the system after
periodic corrections of inflation pres-
sures to maintain them at the levels
stored during an earlier initialization
process.
