The vehicle may roll slightly before
it is held by the gradient assis-
tance after releasing the footbrake.
Two seconds after the footbrake is
released, the vehicle begins to roll, as it
is no longer held with the gradient
assistance.<
The gradient assistance must be reacti-
vated before each use.
Indicator lamp
The transmission indicator lamp
in the instrument cluster goes
out after the engine is started.
>If it does not go out, or if it lights up
during driving, a fault has occurred.
The available functions may be
limited under certain circumstances.
Drive carefully and with the Dynamic
Stability Control (DSC) activated.
Have the system checked by the
nearest BMW center
>If the indicator lamp flashes while
driving, the system is overloaded.
Avoid high loads until the indicator
lamp goes out again permanently.
Shift lightsTo achieve the best possible vehicle
acceleration with a sporty driving style
in the sequential mode, shift lights in
the instrument cluster indicate the
optimum shifting point shortly before
the maximum engine speed is reached.
1 When the maximum engine speed is
approached, yellow indicator fields
(shift lights) in the tachometer light up
consecutively to indicate the
approaching upshift time
2 Shift at the latest when the last indi-
cator field lights up red.Tire replacement, snow chainsFollowing a tire or wheel change and

Dynamic Stability Control (DSC) Flat Tire MonitorTo deactivate DSCPress the DSC button briefly; the indi-
cator lamp will light up and stay on.
The vehicle does not execute the
stability-enhancement and traction-
control functions when DSC is deacti-
vated.
We recommend that you deactivate
DSC for increased traction:
>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 on whenever possible.<
Reactivating the DSCPress the button again; the indicator
lamp goes out.Dynamic Brake Control (DBC)DBC is an integral component of the
DSC system.
If you apply the brakes rapidly, this
system automatically generates
maximum braking force boost and thus
helps to achieve the shortest possible
braking distance in "panic braking" situ-
ations. All of the benefits of the ABS
system are exploited under these
circumstances.
Do not reduce the pressure on the
brake pedal for the duration of the
brake application. When the brake
pedal is released, the DBC is deacti-
vated.
The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires in order to detect and warn of any
substantial pressure loss.
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.

78n
Flat Tire MonitorInitializing the systemInitializing is necessary to familiarize the
system with the correct tire inflation
pressure.
Repeat this process after any changes
in tire inflation pressure, tire replace-
ment or rotation.
1. Check the tire inflation pressure in all
the tires, comparing them with the
inflation pressure table (page 25),
and adjusting their pressure if neces-
sary
2. Turn the ignition key to position 2
3. Press button as long as you need to
until the indicator lamp in the instru-
ment cluster lights up. After a little
while, the indicator lamp will go out
by itself
4. After a few minutes, the Flat Tire
Monitor will accept the current infla-
tion pressure as the value to be
measured against, and from that
point on, can detect and report a flat
tire.
Activating/deactivating the
systemThe system is automatically activated in
ignition key position 2 and conse-
quently is on whenever the vehicle is
operated.
To deactivate the system, tap the
button, the indicator lamp will light up
yellow.
To activate the system, tap the button
again; the indicator lamp goes out.
Deactivate the system when snow
chains are mounted, since false warn-
ings and undetected losses in pressure
are possible under these kinds of
conditions.

Special characteristics of winter tires Snow chainsChoosing the right tireBMW recommends winter tires (M+S
radial tires) for operation under adverse
winter driving conditions. So-called all-
season tires with the M+S identification
mark do indeed possess better winter
traction than summer tires that have the
H, V, W, Y and ZR speed ratings, they
generally fail to provide the same levels
of performance as snow tires.
In the interest of safe tracking and
steering response, install winter tires
made by the same manufacturer having
the same tread configuration on all four
wheels. Do not exceed specified
maximum speeds
Never exceed the maximum
speed for which winter tires are
rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire pressureOnce winter tires wear to a tread depth
of less than 0.16 in (4 mm), their perfor-
mance under winter driving conditions
deteriorates noticeably. Worn tires
should therefore be replaced for safety
considerations.
Inflate tires to specified pressure and
have the wheels balanced every time
the tires or wheels have been replaced.Use narrow-link BMW snow chains
* on
winter tires in pairs only and only on the
rear wheels. Comply with all manufac-
turer's safety precautions when
mounting the chains. Do not exceed a
maximum speed of 30 mph (50 km/h)
with snow chains.
After mounting or removing snow
chains, always reinitialize the sequential
M gearbox
* SMG II, refer to page 65.
It is not possible to mount snow
chains on tires with 18- and
19-inch wheels.
Deactivate the Flat Tire Monitor when
using snow chains. Malfunction warn-
ings and undetected losses in pressure
are a possibility when driving with snow
chains.

page 77.<
