Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to page 21.
Indicator lamp flashes:
The system is active and governs drive
torque and braking force.
If the indicator lamp fails to go out after
the engine is started, or if it comes on
during normal driving:
There is a system malfunction or the
system was deactivated with the
button. You can still drive the vehicle
normally without ASC+T/DSC.
Please consult your BMW center for
repairs.
To deactivate the systemPress the button, the indicator lamp
lights up and remains on continuously.
Depending on equipment options, the
button is marked with ASC or DSC.
With deactivated ASC+T/DSC you are
driving with conventional, unregulated
torque transfer.
In the following exceptional situations,
it may be effective to deactivate the
ASC+T/DSC for a brief period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains.390us728
To reactivate the systemPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with ASC+T/DSC.
An appropriate driving style always
remains the responsibility of the driver.
Do not use the extra safety margins fur-
nished by these systems as an excuse
for taking unnecessary risks.< Dynamic Brake Control (DBC)
*
DBC is an integral component of the
DSC system.
The system responds to sudden, high-
intensity applications of force to the
brake pedal by automatically braking
the vehicle with maximum boost to
achieve the shortest possible braking
distances during "panic stops." This
system exploits all the benefits of ABS.
Do not reduce the pressure exerted
against the brake pedal until the
braking maneuver has been completed.
DBC is deactivated when you release
the brake pedal.

Changing a wheel16. Wheels with hub covers:
Position the hub cover and press it
on tightly
17. If equipped with lug bolt covers:
Align the arrow on the cover with
the line in the wheel and press the
cover into place
18. Check and correct the tire inflation
pressure at the earliest opportunity.
For vehicles with Tire Pressure
Monitor (RDC)
*:
After mounting the spare tire or cor-
recting the inflation pressure, reac-
tivate the system. Refer to
page 101.
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 continued safety, have the
lug bolts checked with a calibrated
torque wrench [torque specification
72 lb-ft (100 Nm)] at the earliest
opportunity.<
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.
Protect valve inserts against dirt using
screw-on valve stem caps. Dirty valve
stems frequently lead to slow pressure
loss.

* tires on
the rear axle:
In the event of a flat tire, it may be nec-
essary to mount the spare tire of dif-
ferent size at the rear. This tire is suit-
able for use in all load and speed
ranges. Nevertheless, you should
remount a tire of the correct size as
soon as possible.<
