You also enjoy the option of having the
system show distances to objects in the
Control Display. The Control Display will
also indicate the presence of objects in
green before they are close enough to
generate a signal tone.
Select "PDC pic." from the "Settings" menu
and confirm your selection. This activates
the PDC display.
The display then appears in the Control
Display whenever PDC is automatically or
manually activated.
The previous display automatically reap-
pears after the system is deactivated.
Confirm in the menu to return to
the previous display.<
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always
remains with the driver. Even when sensors
are involved, there is a blind spot in which
objects cannot be detected. The system is
also subject to the physical limits that apply
to all forms of ultrasonic measurement,
such as those encountered with tow bars
and trailer couplings, as well as thin and
wedge-shaped objects, etc. After initial
detection, low objects such as curbs, etc.,
may disappear again before the system
starts to generate a continuous warning
tone. Loud noises from outside and inside
the vehicle may prevent you from hearing
PDC's signal tone.<
Keep the sensors clean and free of ice
or snow in order to ensure that they
will continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time. Keep the spray at least 4 in (10 cm) away
from the sensors.<
Driving stability control/
DSC Dynamic Stability
Control Your BMW is equipped with an extended
array of systems designed to enhance and
maintain vehicle stability under extreme
conditions. The following section describes
these functions based on DSC and ABS. The concept DSC 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.
The system recognizes any tendency for
the vehicle to assume an unstable attitude
such as oversteer or understeer; it then
counteracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking intervention at
individual wheels. DSC provides optimal
stability within the limits defined by the
laws of physics.
The DSC is operational every time you start
the engine. DSC includes the functionality
of the DTC Dynamic Traction Control and
DBC Dynamic Brake Control.
With its selective braking intervention at the
individual drive wheels, DTC fulfills the
same function as a conventional limited-
slip differential to enhance traction under
difficult driving conditions, such as on
snow, etc. Indicator lamps
The indicator lamp in the Info
Display goes out soon after you
start the engine.
If the indicator lamp flashes:
DSC controls the drive and braking forces.
The indicator lamp stays lit:
DSC has been switched off via the Control
Display.

Technology for comfort, convenience and safety
90 The indicator lamp and the brake
warning lamp remain on continu-
ously:
DSC, DTC and DBC have been
deactivated or a system malfunc-
tion is present.
When the system is off, the stability main-
tenance functions described above are no
longer available. The vehicle will remain
completely operational, however, without
DSC.
Please respond to any malfunctions by
referring the problem to your BMW center.

Activating DTC Dynamic Traction
Control You may find it useful to briefly activate
DTC under the following special circum-
stances:
>When rocking the vehicle and starting off
in deep snow or on loose road surfaces
>When ascending snow-covered hills,
and when driving in deep or on hard-
packed snow
>When driving with snow chains.
Select the "Settings" menu. Select "DTC"
and confirm your entry. DTC is now acti-
vated. The "DTC" indicator lamp in the
Control Display lights up.
When DTC is operating, DSC is
restricted to limited functionality up
to vehicle speeds of approx. 45 mph (70 km/h). Control intervention to maintain
stability is reduced.<
To deactivate DTC again Select the "Settings" menu. Select "DTC"
and confirm your entry. DTC is now deacti-
vated. The "DTC" indicator lamp in the Info
Display goes out. To deactivate DSC Select the "Settings" menu. Select "DSC"
and confirm your entry. DSC is deactivated.
The indicator lamp in the Info Display
remains on continuously.
Deactivating DSC automatically deacti-
vates DTC as well. The systems for
enhancing stability and traction are deacti-
vated, and there is no active braking inter-
vention or torque control.
A status report appears in the Check
Control panel. Please take note of the addi-
tional information in the Control Display
panel.
To maintain optimal stability, drive
with the system on whenever
possible.< To reactivate DSC Select the "Settings" menu. Select "DSC"
and confirm your entry. DSC is now on. The
indicator lamp in the Info Display goes out.
The laws of physics cannot be
repealed, even with DSC. An appro-
priate driving style always remains the
responsibility of the driver. Avoid using the
additional safety margin provided by the
system as an excuse for taking unneces-
sary risks.
When DTC is active, DSC provides only

additional precautions to secure the
vehicle from rolling.
3.Loosen the lug bolts 1/2 a turn
4.Set up the jack beneath the jacking
point closest to the flat tire. Ensure that the
entire surface of the jack's base is in firm
contact with the ground and that the jack
itself is standing completely vertical (not
tilted), and that the fitting on the top of the
jack will align with the rectangular recess
on the vehicle when you raise it, refer to
illustration
5.Jack the vehicle up until the wheel you
are changing is raised from the ground
6.Unscrew the lug bolts and remove the
wheel
7.Remove accumulations of mud or dirt
from the mounting surfaces of the wheel
and hub. Clean the lug bolts
8.Position the spare wheel. Secure the
wheel by turning at least two lug bolts into
opposite bolt holes
9.Screw in the remaining lug bolts.
Tighten all the bolts securely in a diagonal
pattern
10.Lower the jack and remove it from
beneath the vehicle.
11.Tighten the lug bolts in a diagonal
pattern
12.Check and correct the tire inflation
pressure at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.
Vehicles with RDC Tire Pressure Monitor:
After mounting a spare tire or correcting the inflation pressure(s) always remember
to reinitialize the system, refer to page 92.
The vehicle jack is designed for
changing wheels 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 safety, always have the lug bolts
checked with a calibrated torque wrench to
ensure that they are tightened to the spec-
ified torque of 140 Nm as soon as
possible.<
Reverse the removal sequence to store the
wheel and tools in the vehicle.
When you mount wheels other than Orig-
inal BMW light-alloy wheels, different lug
bolts may also be required.
Always have damaged tires replaced and
the wheel and tire assembly rebalanced at
the earliest possible opportunity.
Battery Battery care The battery is 100% maintenance-free, i. e.,
the electrolyte will last for the life of the
battery when the vehicle is operated in a
temperate climate.
For all questions that regard the
battery, please consult your BMW
center. Since the battery is maintenance-
free, the following is for your information
only.< Charging the battery Only charge the battery in the vehicle via
the terminals in the engine compartment
with the engine off. Connections, refer to
Jump starting on page 187.
To avoid short circuits, as well as
possible fires and personal injury,
always disconnect the cable from the
battery's negative terminal before working
on the vehicle's electrical system.<
