190nChanging a wheel
Safety measures in the event of a
flat tire or wheel change:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat,
surface. Switch on the hazard warning
flashers.
Turn the steering wheel to the straight-
ahead position, remove the key and
engage the steering lock. Shift into 1st
or reverse (selector lever in Park with
automatic transmission) and engage
the parking brake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area (behind a guardrail,
for instance).
If necessary, set up your warning trian-
gle or portable hazard warning lamp on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all safety guidelines and regula-
tions.
Change the wheel only on a level, firm
surface which is not slippery. Avoid
jacking the vehicle on a soft or slippery
support surface (snow, ice, loose
gravel, etc.), since it could slide side-
ways.Position the jack on a firm support
surface.
Do not place wooden blocks or similar
objects under the jack. If this is done,
the jack might not be able to reach its
full support capacity because of the
limited height.
Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack – risk of fatal injury. <
What you will need
In order to avoid rattling noises later,
note the position of the tools when you
remove them and return them to their
original position when you are through
using them.

For vehicles with Tire Pressure
Control (RDC)
*:
After mounting the spare tire or cor-
recting the inflation pressure, reacti-
vate the system. Refer to page 103.
The vehicle jack is designed for
changing tires only. Do not
attempt to raise another vehicle model
with it or to raise any load of any kind.
To do so could cause accidents and
personal injury.
To ensure continued safety, have the
lug bolts checked with a calibrated
torque wrench [torque specification

193nChanging a wheel Battery
When storing the wheel, take care to
ensure that you do not damage the
retaining pin in the spare tire recess.
If light-alloy wheels other than original
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced.
Size 255/40 R17 94 W
* tires on
the rear axle:
In the event of a puncture or other tire
failure, it may be necessary to mount
the spare tire of different size at the
rear. This tire is of full capacity in all
load and speed ranges. Nevertheless,
mount a tire of the correct size as soon
as possible. <
Battery posts, terminals, and re-
lated accessories contain lead
and lead compounds. Wash hands after
handling. <
Installation location
The battery is located behind the right-
hand side trim panel in the luggage
compartment.
Fold the trim panel down with the
handle at the top. On the sport wagon,
press the button.
If a subwoofer
* is installed on the sport
wagon, loosen the T-screw and swing

Maintenance
The battery is absolutely maintenance-
free, that is, the original electrolyte will
normally last for the service life of the
battery under moderate climatic condi-
tions.
Symbols
You will find the following symbols on
your vehicle battery. To avoid injury,
please comply with the corresponding
precautions whenever you work with or
near the battery.
Please read the following infor-
mation before working with the
battery.
Wear eye protection. Do not al-
low particles containing battery
acid or lead to come into con-
tact with your eyes, your skin, or your
clothing.
Battery acid is extremely corro-
sive. Wear eye protection and
protective gloves. Do not tip the
battery. Battery acid can leak from the
ventilation openings.
Be sure that children keep well
away from batteries and battery
acid.

202nTowing the vehicle
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it is no longer
possible to control vehicle response. <
Tow-starting
It is not possible to start the engine of
vehicles equipped with an automatic
transmission by towing or pushing.
For instructions on jump starting, refer
to page 200.
Never attempt to use your vehicle to
push another vehicle, since damage to
the energy-absorbing bumpers could
result.
Towing a vehicle with automatic
transmission
1 Place the selector lever in position N.
2 Towing speed: Max. 45 mph (70 km/h).
3 Towing distance: Max. 95 miles (150 km).
4 Leave the ignition key in position 1 to ensure that the brake lamps, turn sig-
nals, horn and windshield wipers re-
main operative, and to prevent the
steering lock detent from engaging.
5 Switch on the hazard warning flash- ers (observe country-specific regula-
tions).
Find some means of identifying the ve-
hicle in tow, for instance, place a sign
or warning triangle in the rear window.
Make sure that the ignition key
remains in position 1 even when
the electrical system has failed to pre-
vent the steering lock from engaging.
The steering and brakes are without
power assist when the engine is off.
This means that increased effort is
required for steering and braking. <
Towing with a commercial
tow truck
> Do not tow with sling-type equip-
ment.
> Use a wheel lift or flat bed carrier.
> Please comply with applicable towing
laws.
Never allow passengers to ride in
a towed vehicle for any reason. <

208nASC+T/DSC*
Precision sensors monitor the number
of revolutions of the wheels. When
equipped with DSC, they also monitor
steering angle, lateral acceleration,
brake pressure and the movement of
the vehicle around its vertical axis.
If differences in the wheel speeds
occur, the system counteracts the dan-
ger of wheelspin by reducing torque. If
necessary, the system also responds
with additional brake applications at the
rear wheels, and at all 4 wheels with
DSC.
In addition, DSC permanently monitors
the vehicle's current operating condi-
tion and compares it with an ideal con-
dition that is calculated from the sen-
sor's signals. If deviations from this
occur (understeering or oversteering,
for instance), DSC can stabilize the
vehicle in the fraction of a second by
reducing engine output and with the
assistance of braking intervention at in-
dividual wheels. As a result, dangerous
skids can be prevented even as they
are just beginning. You may need some time to become
accustomed to this system intervention.
However, it guarantees optimum drive
force and driving stability.
The braking intervention may be
accompanied by a certain degree of
noise.

Overview
213nTire Pressure Control (RDC)*
The Tire Pressure Control system (RDC)
assumes the task of regular tire pres-
sure checks for you. The tire pressure is
monitored at all four wheels, even when
the vehicle is moving.
Behind the valve stem in every wheel,
there is an electronic chip which is
designed for severe-duty applications
and long service life. It contains a pres-
sure sensor, a transmitter and a battery.
The pressure is measured in extremely
short time intervals and then transmit-
ted by a radio signal. If an irregularity is
detected, the transmission rate is
increased.
394de304
Near every wheel, there are antennas in
the body which receive the signals from
all four wheels. A central electronics
system evaluates the quadruple signals
and forwards any changes.
The RDC provides an important contri-
bution to driving safety.

214nIntegrated rear suspension Level control system*
The control arms on the patented inte-
grated aluminum rear axle assembly are
not mounted directly on the body. They
are mounted elastically on a chassis
sub-frame which is joined in turn with
elasticity to the vehicle body. The result-
ing double elastic suspension system
effectively absorbs the forces resulting
from bumps and road surface irregulari-
ties.
The compliance rates of the integrated
rear axle assembly's control arm mounts
have been precisely calibrated to help
provide supplementary adjustment in
the tracking angle of the rear wheels
(programmed self-steer effect). The ulti-
mate result is enhanced safety and con-
trol under all conditions.
390de114
The illustration shows the rear axle of the
sedan. With the lightweight, compact
rear axle of the sport wagon, the shock
absorbers are positioned at an angle.
The level control system for the rear
axle maintains constant ground clear-
ance of your vehicle, even when carry-
ing a load.
To achieve this, the vehicle is equipped
with air struts at the rear axle instead of
conventional shock absorbers and steel
suspension springs. With the help of
two sensors, an electronic control unit
calculates the height of the body at all
times and, if it is required, it allows air
which is generated in a compressor to
flow into the air springs.
As a result of the pressure increase in
the air springs, the level control system
ensures not only constant ride height,
but also ride comfort which is indepen-
dent of the load the vehicle is carrying.
