DTC Dynamic Traction Control
In special driving states, e.g. in deep snow,
DTC ensures maximum forward momen-
tum. The gain in forward momentum also
involves a reduction in driving stability.
DTC is active up to 45 mph/70 km/h.
Activating DTC
Press the DSC button briefly; the
DTC indicator lamp in the instru-
ment cluster lights up permanently.
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 sur-
faces
>When ascending snow-covered hills,
and when driving in deep or on hard-
packed snow
>When driving with snow chains.
When DTC is active, DSC provides
only limited system response up to a
speed of approx. 45 mph/70 km/h. Control
intervention for stability-enhancement is
reduced.<
Deactivating DTC again
Press the DSC button again; the DTC indi-
cator lamp in the instrument cluster goes
out. DSC is available once again without
restriction.
Deactivating DSC
Press the DSC button for at least 3 sec-
onds; the DSC indicator lamp in the instru-
ment cluster lights up permanently. DSC is
deactivated.
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 message appears on the Control Display.
Please note any supplementary information
that appears there.
To maintain optimal stability, drive
with the system on whenever possi-
ble.<
Reactivating DSC
Press the DSC button again briefly; the
indicator lamp in the instrument cluster
goes out. DSC is now activated.
The laws of physics cannot be
repealed, even with DSC. An appro-
priate driving style always remains the
responsibility of the driver. Therefore, do
not reduce the additional safety margin
again by taking risks.
Do not make any modifications to the DSC
system. Never allow anyone other than
authorized professional technicians to
carry out service or repairs on the DSC sys-
tem.<
DBC Dynamic Brake Control
When you apply the brakes rapidly, this
system automatically produces the maxi-
mum braking force boost and thus helps to
achieve the shortest possible braking dis-

natural, even pressure drop in all four
tires.<
In the following situations, on the other
hand, there can be delays in detecting tire
pressure losses, and even system failure:
>When you are driving on snow-covered
or slippery road surfaces
>If you are using a sports driving style:
slip on the drive wheels, high lateral
acceleration
>False alarms and undetected loss of
pressure may occur when you are driv-
ing with snow chains fitted
>When you are driving with the compact
wheel, the Flat Tire Monitor is unable to
function.
Initializing the system
Perform the initialization immediately
after correcting the inflation pressure,
after changing a tire or changing a wheel or
all wheels. A drive is necessary for this pur-
pose.<
Control Center, for principle details, refer to
page 16:
1.Before beginning driving, start the
engine, but do not drive off
2.Open the menu
3.Select "Vehicle settings" and press the
controller
4.Select "FTM" and press the controller
5.Select "Set tire pressure" and press the
controller
6.Select "Yes" and press the controller
7.Drive off.
The message "Initializing" is displayed.It takes a few minutes before the Flat Tire
Monitor can detect and report a flat tire.
After the initialization is completed, the
message "Active" is displayed.
If a flat tire is detected during initialization,
a message appears on the Control Display.
When driving with snow chains or
with the compact wheel, do not initial-
ize the system.<
Flat tire
Indicator lamp
The symbol in the instrument clus-
ter lights up in red and a simulta-
neous message appears on the
Control Display. In addition, an acoustic
signal sounds.
Please note any supplementary information
that appears on the Control Display. You
can find more information on the Check
Control starting on page 68.
1.Reduce speed and stop the vehicle
carefully. Avoid sudden braking and
steering maneuvers
2.Identify damaged tire
If identification is not possible,
contact your BMW center.<
3.Replace the damaged wheel, refer to
Changing a tire on page 187.
Vehicles with run-flat tires:
1.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden
braking and steering maneuvers. Do
not exceed a vehicle speed of 50 mph/
80 km/h
Due to the reinforcement on the
edges of the run-flat tires, inflation
pressure loss can not usually be recog-
nized from the outside, refer to Run-flat
tires on page 175.<
2.To continue driving, comply with the
instructions for driving with damaged
tires on page 175.

Wheels and tires
176 can estimate the possible distance for con-
tinued driving on the basis of the following
guide values:
>With low load:
1 to 2 persons without luggage:
Approx. 155 miles/250 km
>With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
Approx. 90 miles/150 km
>With full load:
4 persons or more, luggage compart-
ment full:
Approx. 30 miles/50 km.
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. With infla-
tion pressure loss, the driving characteris-
tics change, for example reduced track sta-
bility on braking, extended braking
distance, and altered self-steering charac-
teristics.
For safety reasons, BMW recommends that
you do not have damaged run-flat tires
repaired and that you consult your BMW
center in this case.<
Snow chains*
BMW only tests certain snow chains, clas-
sifies them as road-safe and approves
them. Consult your BMW center for more
information. BMW recommends only using
these approved, narrow-link snow chains.
These snow chains are approved exclu-
sively for use on summer or winter tires in
pairs on the rear wheels.
Observe the manufacturer's instructions
when installing snow chains.
Do not exceed a vehicle speed of 30 mph/
50 km/h with the chains mounted.
After mounting snow chains, do not
activate the Flat Tire Monitor.
When you are driving with snow chains, it
can be beneficial to switch off DSC briefly,
refer to page 78.<
