Dynamic Stability Control (DSC)The conceptDSC maintains vehicle stability, even in
critical driving situations.
DSC is operational every time you start
the engine.
DSC incorporates the Dynamic Traction
Control (DTC) and Cornering Brake
Control (CBC) functions.
For information on vehicles with all-
wheel drive, refer to page 88 ff.Indicator lamps
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: DSC con-
trols the drive and braking forces
>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 lamp and the
brake warning lamp continu-
ously light up in 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.
Indicator and warning lamp for
Canadian models.
Deactivating the DSC/activating
the DTCPress the DSC button briefly, the indi-
cator lamp comes on and remains lit.
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 on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on
>When driving with snow chains.
Traction is increased by deactivating
the control systems that enhance trac-
tion under normal conditions.

Dynamic Stability Control (DSC) – 325xiThe conceptDSC maintains vehicle stability, even in
critical driving situations.
DSC is operational every time you start
the engine.
DSC incorporates the Automatic Differ-
ential Brake (ADB-X) and Cornering
Brake Control (CBC) functions.Indicator lamps
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: DSC con-
trols the drive and braking forces
>The indicator lamp stays lit: DSC has
been switched off with the button;
ADB-X is operational. ADB-X control
intervention is not indicated.
If the indicator lamp fails to go out
when you press the DSC button
again, this indicates a malfunction in
the DSC and ADB-X systems; the sta-
bility enhancement functions are no
longer available.<
The vehicle will remain completely
operational, however, without DSC. In
the event of a fault, please consult your
BMW center.
To deactivate DSCPress the DSC button; the indicator
lamp comes on and remains lit.
DSC is switched off, and ADB-X reverts
to its maximum torque-transfer mode.
In the following rare situations, it may
be effective to deactivate the DSC 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 DSC acti-
vated whenever possible.<

Flat Tire Monitor*The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires. The system alerts you whenever
the inflation pressure of a tire falls sig-
nificantly below the pressure of another
tire.
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.Functional requirementsIn order for the Flat Tire Monitor to learn
the correct tire inflation pressure,
please do the following:
1. Check the tire inflation pressures in
all tires
2. Compare them with the tire inflation
pressure table on page 26 and cor-
rect them, if necessary
3. Initialize the system.
System limitations
The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors and does not detect
the balanced and very gradual pressure
loss that takes place in all four tires
over an extended period of time.<
On the other hand, the following situa-
tions can lead to a delayed detection of
pressure loss and even to the system
not functioning:
>Driving on snow-covered or slippery
roads
>Performance-oriented driving: slip at
the drive wheels, high levels of lateral
acceleration
>When driving with snow chains, false
warnings and undetected pressure
losses may occur
>When driving with a space-saver
spare tire, the Flat Tire Monitor can-
not function.
Initializing the system
Each time you correct the pres-
sure in a tire, or change a wheel or
tire, reinitialize the system immediately
afterwards. This requires a bit of driv-
ing.<
1. Before driving off, start the engine
but do not start driving
2. Press the button as long as you need
to until the yellow indicator lamp in
the instrument cluster lights up for a
few seconds
3. Drive off.
It takes a few minutes before the Flat
Tire Monitor can detect a flat tire and
issue a warning.

When driving with snow chains or
a space-saver spare tire, do not
initialize the system.<
Flat tire
The indicator lamp in the instru-
ment cluster lights up red. This
visual alert is accompanied by
an acoustic warning signal.
1. Carefully reduce speed and come to
a stop. Avoid sudden braking and
steering maneuvers
2. Determine which wheel is damaged
If this cannot be determined, con-
tact your BMW center.<
3. Replace the damaged wheel, refer to
Changing a wheel on page 147.
After replacing the damaged tire, initial-
ize the system.
Vehicles with Run Flat tires:
1. Carefully reduce your speed to under
50 mph / 80 km/h. Avoid strong
braking and steering maneuvers. Do
not exceed a speed of 50 mph /
80 km/h.
Because the sides of Run Flat
tires are reinforced, a drop in infla-
tion pressure usually cannot be
detected from the outside, refer to Run
Flat tires, page 150.<
2. To continue driving, follow the
instructions under Driving with a
damaged tire on page 151.
System malfunction
The indicator lamp in the instru-
ment cluster lights up yellow.
The Flat Tire Monitor is malfunc-
tioning or out of order. Please refer the
problem to your BMW center.
Brake force displayThe brake force display indicates to the
driver of the vehicle behind you how
hard you are braking your vehicle.
The display has two levels:
>Normal braking: the brake lamps
among the rear lamps and the center
brake lamp light up
>Hard braking or use of ABS: the tail
lamps light up with the same bright-
ness as the brake lamps and thereby
intensify the visual effect of the brake
lamps.

the tire sidewall, refer to Changing a
wheel. In this case, use only Run Flat
winter tires, since no spare tire is pro-
vided in the event of a flat tire.Tire condition, tire pressureAt tread depths below approx. 3/16 in /
4 mm, winter tires display a perceptible
decrease in their ability to cope with
winter driving conditions, and should be
replaced in the interest of safety.
Comply with the specified tire inflation
pressures — and be sure to have the
wheel and tire assembly balanced
every time you change a tire or wheel.Snow chains*Only certain snow chains have been
tested by BMW and determined and
approved as roadworthy. Consult any
BMW center for details. BMW recom-
mends using only these approved fine-
link snow chains. Use them in pairs on
either summer or winter tires, but only
on both rear wheels.325xi: in an extreme emergency – for
instance, with the vehicle stuck on one
side, or when obstructions make it
impossible to reach one tire – a chain
may also be mounted on just one tire
for the limited period needed to resolve
the problem.
Comply with all manufacturer's safety
precautions when mounting the chains.
Do not exceed a speed of 30 mph /
50 km/h when using snow chains.
You cannot mount snow chains on the
following tires:
225/50 R 16
225/45 R 17
245/40 R 17
225/40 R 18
255/35 R 18
Do not initialize the Flat Tire Moni-
tor after mounting snow chains to
the tires.
When driving with snow chains, it may
be useful to turn off the DSC for a short
time, refer to page 87 or 88.
