been switched off: add engine
oil at the earliest opportunity, such as
the next time you stop to refuel.

Automatic Stability Control plus Traction (ASC+T)*The conceptASC+T optimizes vehicle stability and
traction, especially when you are start-
ing off, accelerating or when going
through curves.
ASC+T is ready each time you start the
engine.
ASC+T contains the Automatic Differ-
ential Brake (ADB) and Cornering Brake
Control (CBC) functions.
Additional information on ASC+T is
found in the "Technology" brochure.Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition,
refer to page 19.
>The indicator lamp flashes: ASC+T is
actively controlling drive torque and
braking intervention
>The indicator lamp stays lit: ASC+T
has been switched off with the but-
ton; ADB is operational. ADB control
intervention is not indicated.
The indicator and the brake
warning lamps will remain on
continuously yellow:
The ASC+T and ADB have been
switched off manually or there is
a system malfunction.
You can still drive the vehicle as normal
without ASC+T.
In the event of a fault, please consult
your BMW center.

cator lamp comes on and stays on.
ASC+T has been switched off; ADB is
operational.
In the following rare situations, it may
be effective to activate the ADB 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.<

Deactivating the ASC+T and ADBPress the ASC button for at least 3 sec-
onds; the indicator lamps and the yel-
low brake warning lamp come on and

control.

out. ADB is deactivated.
The laws of physics cannot be
repealed even with ASC+T. An
appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the sys-
tem as an excuse for taking risks. OverviewControlsMaintenanceRepairsDataIndex

Dynamic Stability Control (DSC)*The conceptDSC maintains vehicle stability, even in
critical driving situations.
DSC is operational every time you start
the engine.
DSC contains the Dynamic Traction
Control (DTC) and Cornering Brake
Control (CBC) functions.
Additional information on DSC is found
in the "Technology" brochure.Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition,
refer to page 19.

>The indicator lamp stays lit: DSC has
been switched off with the button;
DTC and DBC are operational. DTC
control intervention is not indicated.
The indicator and the brake
warning lamps will remain on
continuously yellow:
The DSC, DTC and DBC have
been switched off manually or
there is a system malfunction.
The vehicle will remain completely
operational, however, without DSC. In
the event of a fault, please consult your
BMW center.

DSC is deactivated; DTC is operational.
In the following rare situations, it may
prove useful to activate the DTC for a
brief period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains
>When driving on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on.

Under these special circumstances
traction is increased by deactivating the
control systems that enhance traction
under normal conditions.To switch DSC and ADB offHold the DSC button down for at least
3 seconds. The indicator lamp and the
yellow brake warning lamps light up
and remain on continuously.
The systems for enhancing stability and
traction are deactivated, and there is no
active braking intervention or torque
control.
To maintain vehicle stability,
always drive with the DSC acti-
vated whenever possible. lamp or the indicator lamps will go out.
DTC is deactivated.
The laws of physics cannot be
repealed even with DSC. An
appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the sys-
tem as an excuse for taking risks.
Whenever the DTC is activated, the
DSC is switched off and performs minor
stabilizing intervention.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<

13. Wheels with full wheel covers*:
place the wheel cover with the
valve opening – see arrow – over
the valve. Use both hands to press
the cover securely onto the rim
14. Check and correct the tire inflation
pressure at the earliest opportunity.
Vehicles with Tire Pressure Monitor
(TPM)/Flat Tire Monitor:
After mounting the spare tire or
correcting the tire inflation pres-
sure, reinitialize the system, refer to
page 92.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirty
valve stems frequently lead to slow
pressure loss.
Do not place the full wheel cover
on the space-saver spare tire,
since this could damage the cover.<
The vehicle jack is designed for
changing wheels only. Do not
attempt to raise another vehicle model
with it or to raise any other type of load.
To do so could cause accidents and
personal injury.
To ensure continued safety, have the
tightness of the torque bolts checked
with a calibrated lug wrench – torque
specification: 88.5 lb ft/120 Nm – at the
earliest opportunity.<
When storing a wheel in the spare tire
recess, take care to avoid bending the
threaded rod.
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.
Driving with the space-saver
spare tireDrive cautiously. Do not exceed a
speed of 50 mph / 80 km/h.
Be aware that vehicle handling may be
altered. Anticipate, e.g., reduced track-
ing during braking, longer braking dis-
tances and changed steering charac-
teristics when approaching limit
conditions. These handling characteris-
tics will be even more pronounced if
winter tires are mounted.
Only one space-saver spare tire
may be mounted at one time.
Mount a wheel and tire of the original
size at the earliest possible opportu-
nity.<
