Airbags
The airbags do not deploy in
response to minor collisions, rear
impacts and certain kinds of vehicle
rollover.<
For your safety, comply with the
following instructions for the
airbags. If you do not, the airbags may
not be able to provide their maximum
protection. All passengers in the vehicle
should be aware of and comply with
these directions:
The airbags are supplemental restraint
devices designed to provide extra
protection; 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
vehicle rollover, or collisions from the
rear. In these instances, the safety belt
provides optimal protection.
Airbags are located under cover panels
in the steering wheel, in the instrument
panel, in the side trim panels in the
front and rear
*, in the roof panels, and
in the sides of the inside roof lining.
Adjust your seat to a position that
provides maximum distance between
you and the steering wheel, the instru-
ment panel and the door while still
allowing comfortable and safe access
to all vehicle controls.
To avoid sustaining hand and arm inju-
ries, always grasp the steering wheel
on the rim with the hands at the 9 and
3 o'clock positions. Do not place your
hands on the center pad.
Never allow any objects to obstruct the
area between the airbag and an occu-
pant.
Do not use the cover panel above the
passenger-side airbag as a storage
area.
Do not apply adhesive materials to the
cover panels of the airbags, cover them
or modify them in any other way.
Do not install a rear-facing child-
restraint system in the front passenger
seat of this vehicle.
Children under 13 years of age and less
than 5 ft (150 cm) tall should ride only in
the rear seat. Infants or small children
should never be held on the lap of a
passenger.
If your vehicle is equipped with side
airbags in the rear passenger area
*, be
sure that child restraints are mounted
correctly, with the greatest-possible
distance between the airbags in the
side trim panels. 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 triggered. always sit upright 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: in
the event of deployment the airbag
could cause a serious or fatal injury.
Please note that the word Airbag
embossed on the door trim panel indi-
cates the airbag's location.
Accident research shows that the
safest place for children in an automo-
bile is in the rear seat. However, a child
sitting in the rear seat and not properly
restrained may place his or her head on
or near the airbag, if one is installed.
For example, a child Ñ even though
belted Ñ may fall asleep with his or her
head against the side airbag. It may be
difficult for a driver to ensure that chil-
dren in the rear seat will remain prop-
erly positioned at all times and do not
place their heads on or near the side
airbag.
Therefore, we recommend that the
rear-seat side airbags, if installed, be
deactivated if children will be riding in
the rear seat.
The rear-seat side airbags may already
have been deactivated, either at the

Vehicles with automatic transmis-
sion:
Do not move the selector lever from
position "P" until the engine is running
(ignition key position 2).
Your vehicle is equipped with an inter-
lock. Therefore, the ignition key cannot
be turned to position 0 and removed
until the selector lever is in

removed in this position.
After removing the key, turn the
steering wheel slightly to the left or right
until the lock engages.
The sound system remains operational
for approx. 20 minutes after you switch
off the ignition (ignition key in position 0
or key extracted). Simply switch it back
on.Steering unlocked You will find that it is often easier to turn
the ignition key from position 0 to posi-
tion 1 when you move the steering
wheel slightly to help disengage the
lock.
Individual electrical accessories are
ready for operation.
Before starting>Engage the parking brake
>Gearshift lever in neutral, or, with an
automatic transmission, selector
lever in position "P"
>Depress the clutch pedal.
Do not allow the engine to run in
enclosed spaces. 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 unat-
tended vehicle with a running engine
represents a potential safety hazard.<
When driving, standing at idle,
and parking the vehicle, take care
to avoid contact between the exhaust
system and flammable materials (grass,
hay, leaves, etc.). Such contact could
lead to a fire, resulting in serious
personal injury and property damage.<
>Start the engine. Do not press the
accelerator pedal.

Parking brake Manual transmission The parking brake is designed primarily
to prevent the vehicle from rolling when
it is parked. It operates on the rear
wheels.To engageThe detent engages automatically, the
indicator lamp in the instrument cluster
comes on when the ignition key is in
position 2, refer to page 18.To releasePull up slightly on the lever, press the
button (arrow) and lower the lever.
If exceptional circumstances
make it necessary to engage the
parking brake while the vehicle is in
motion, do not pull it with excessive
pressure. Keep your thumb pressed
against the release button while care-
fully pulling the lever up to apply
moderate pressure.
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.
Vehicles with manual transmission:
Always engage the parking brake when
parking on hills and inclined surfaces,
as first gear or reverse may not provide
adequate resistance to rolling.
Vehicles with automatic transmission:
place the selector lever in "Park."<
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.
Reverse Select only when the vehicle is
stationary. Press the shift lever to the
left to overcome the slight resistance.
As you do this, the backup lamps will
turn on automatically when the ignition
key is in position 2.
Do not hold the vehicle in place on
slopes by slipping or "riding" the
clutch. Use the parking brake instead.
Riding the clutch leads to severe and
premature clutch wear.<

Automatic transmission with Steptronic
*
You can drive as with a normal auto-
matic transmission. In addition, you can
also shift manually.
When you move the selector lever from
the "D" position to the left into the M/S
range, the performance-oriented shift
programs of the automatic transmission
are engaged. Steptronic enters the
manual selection mode and executes
the desired shift whenever you tap the
selector lever in the direction indicated
by "+" or "Ð." Whenever you want to use
automatic again, just shift the selector
lever toward the right to position D.

Starting the engineThe engine can only be started in
selector lever positions P ("Park") or N
("Neutral").Range selectionA detent prevents inadvertent shifts to
the "Reverse" or "Park" selector lever
positions. To disengage the detent,
press the button on the front side of
the shift knob (arrow).
While the vehicle is stationary and
before shifting out of "Park" or
"Neutral," depress the footbrake in
order to disengage the selector lever's
lock mechanism (Shiftlock).
Hold the footbrake down until starting
off. Otherwise the vehicle will "creep"
when a drive position is engaged.<
To prevent the vehicle from
starting off on its own, always
move the selector lever to position P
or N and engage the parking brake
before leaving your vehicle with the
engine running.

Automatic Stability Control plus Traction (ASC+T)

The conceptThis system optimizes vehicle stability
and traction, especially when just
starting off, when accelerating or when
going through curves.
ASC+T recognizes the danger present
in traction loss and will increase driving
stability and traction by reducing the
engine's output, and if necessary, by
applying the brakes to the rear wheels.
ASC+T is ready each time you start the
engine.
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition,
refer to pages 18, 19.
The indicator lamp flashes:
ASC+T controls the drive and braking
forces.
The indicator lamp fails to go out
after the engine is started, or it
comes on during normal driving and
stays on:
There is a system malfunction or the
system was deactivated with the
button. Consequently, interventions to
increase driving stability (as described
in the preceding column) are no longer
available. You can still drive the vehicle
perfectly well without ASC+T.
In the event of a fault, please consult
your BMW center, refer to
pages 18, 19.<
Deactivating the ASC+TPress the button; the indicator lamp
comes on and stays on.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.
In the following rare situations, it may
prove useful to deactivate the ASC+T
for a brief period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains.
To maintain vehicle stability,
always drive with the ASC+T acti-
vated whenever possible.<

ASC+T Dynamic Stability Control (DSC)
*
Reactivating the ASC+TPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with ASC+T. It will
always be the driver's responsibility to
drive in a manner that matches road
conditions. This is why you should not
use the additional safety margin the
system provides as an excuse to take
risks.<
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, it recognizes
unstable vehicle conditions, such as
under- or oversteering, and, within
physically feasible limits, helps keeping
the vehicle on a steady course by
reducing the engine speed and brake
applications to the individual wheels.
The DSC is operational every time you
start the engine. DSC incorporates the
ADB and CBC (Cornering Brake
Control) functions.
The Automatic Differential Brake (ADB)
relies on selective braking applications
at the drive wheels to furnish the func-
tionality of a conventional limited-slip
differential for enhanced traction in crit-
ical driving conditions such as those
encountered on snow-covered road
surfaces, etc.
The ADB is operational when DSC is
switched off.
Indicator lamp
The indicator lamp on the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to pages 18, 19.
The indicator lamp flashes:
DSC controls the drive and braking
forces.
The indicator lamp stays lit:
DSC has been switched off with the
button; ADB is operational.
ADB control intervention is not indi-
cated.
The indicator and the brake
warning lamps will remain on
continuously:
The DSC, ADB and DBC have
been switched off with the
button or are defective.
The vehicle will remain completely
operational, however, without DSC. In
the event of a fault, please consult your
BMW center, refer to pages 18, 19.

Tire Pressure Monitor (RDC)
*
The conceptRDC monitors the tire pressures at all
four wheels while the vehicle is moving.
The system provides an alert whenever
the inflation pressure drops significantly
below the specified pressure in one or
more tires.
In order for the system to "learn" the
correct tire inflation pressure, check the
inflation pressures in all tires according
to the inflation pressure table on
page 25 and make corrections as
necessary. Then activate the system.
This indicator lamp in the instru-
ment cluster will inform you if
the tire pressure is not correct.
To activate the system1. Turn ignition key to position 2 (do not
start the engine)
2. Press the button long enough for the
yellow indicator lamp in the instru-
ment cluster to light up for a few
seconds
3. After a few minutes driving time,
RDC sets the current inflation pres-
sures in the tires as the target values
to be monitored.
You will only have to repeat this proce-
dure following a correction of the tire
inflation pressure. Otherwise, RDC
functions automatically when the igni-
tion key is in position 2, and thus oper-
ates whenever the vehicle is driven.
In the event of loss in inflation
pressureIf the inflation pressure has dropped
significantly over a long period of time
(which is normal for any tire), the yellow
indicator lamp will come on.
This alerts you to have the tires inflated
to the specified pressures as soon as
possible.
If you are prompted to check the
tire pressure shortly after a
correction has been made, this indi-
cates that the corrected values were
not accurate. Please check the inflation
pressure again and make corrections
according to the inflation pressure
table. Then activate the system once
again.<

Tire Pressure Monitor (RDC)
*
In the event of a flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, an acoustic
signal is sounded.
If this occurs, reduce vehicle speed
immediately and stop the vehicle in a
safe location. Avoid hard brake applica-
tions. Do not oversteer. Replace the
wheel and flat tire.
The space-saver spare tire is
provided for temporary use only in
the case of a tire failure. It does not
have RDC electronics and is not moni-
tored. The spare tire
that has the same
dimensions as the tires already
mounted on the vehicle is equipped
with the necessary RDC electronics
and will be also monitored once the
tires have been mounted and the
system activated.<
The RDC cannot alert you to
severe and sudden tire damage
caused by external factors.<
Have the tires changed by your
BMW center.
Your BMW center has the information
needed for working with RDC and is
equipped with the necessary special
tools.<
System interferenceLocal devices using the same radio
frequency can interfere with the RDC.
The yellow indicator lamp will come on
during the malfunction.
The indicator lamp also comes on
>in the event of a system fault
>if a wheel is mounted without the
appropriate electronics
>if, in addition to the spare tire, addi-
tional wheels with RDC electronics
are on board.
Please contact your BMW center for
additional information.

Flat Tire Monitor
*
The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires in order to detect and warn of any
substantial pressure loss.
The system actually detects pressure
loss by monitoring differences in the
relative speeds of the four wheels. It
interprets variations outside specified
limits as severe pressure loss, and then
responds by generating a warning.
Initializing the systemInitializing is necessary to familiarize the
system with the correct inflation pres-
sure.
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement. Do not carry out further
system initialization after adjusting the
inflation pressure and letting the system
"learn" the correct pressures.
1. Check the tire inflation pressures in
all the tires, comparing them with the
inflation pressure chart on page 25
and adjusting their pressure if neces-
sary
2. Turn the ignition key to position 2
3. Press the button as long as you need
to until the indicator lamp on the
instrument cluster lights up. After a
little while, the indicator lamp will go
out by itself
4. After a few minutes driving time, the
Flat Tire Monitor adopts the current
pressure levels as the reference, and
from that point on, can detect and
report a flat tire.

Flat Tire Monitor
*
To activate/deactivate the systemThe Flat Tire Monitor automatically
assumes operation whenever you turn
the ignition key to position 2. Unless
manually deactivated, it is always on
during normal vehicle operation.
To deactivate the system: press the
button, the yellow indicator lamp comes
on.
To activate the system: press the
button again, the indicator lamp goes
out.
You should deactivate the system
before driving with snow chains, as the
chains can generate spurious warnings
and/or prevent the system from
detecting actual pressure loss.
Flat tire warning
The red warning lamp in the
instrument cluster lights up to
warn of pressure loss and tire
failure. This visual alert is accompanied
by an acoustic warning signal. Reduce
your speed immediately, and steer and
brake gently as you bring the vehicle to
a stop.
To reset the warning lamp: after
replacing the damaged tire you will
need to reset the red warning lamp
manually: maintain pressure on the Flat
Tire Monitor button until the warning
lamp goes out. Then reinitialize the
system.
The Flat Tire Monitor cannot
provide you with advance warning
of sudden and severe tire damage
caused by external factors.
The system also does not detect the
gradual and minor loss of pressure that
all tires display over extended periods
of time.<
Check tire inflation pressures on a
regular basis, correcting them as
necessary, refer to page 24.
The system may respond to operation
on slippery or snow-covered road
surfaces with false warnings or delays
in detecting actual pressure loss.
Performance-oriented driving (slip at
the drive wheels, high rates of lateral
acceleration) can also increase the time
that the Flat Tire Monitor requires to
detect a flat.<
System malfunctionsThe yellow indicator lamp in the instru-
ment cluster lights up and remains on
until the problem is corrected.
Please refer the problem to your BMW
center.
