roads

Activating DTC
Press the button; the indicator lamps for DTC in
the instrument cluster come on.
For better control
If the indicator lamp flashes:
DTC is regulating the drive and braking
forces.
If the indicator lamps are on:
DTC has been activated.
Deactivating DTC
Press the button again; the DTC indicator
lamps in the instrument cluster go out.
Drive-off assistant
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the parking brake for this.
1.Hold the car in place by depressing the
brake.
2.Release the brake and drive off without
delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Drive off without delay after
releasing the brake. Otherwise, the drive-off assistant will no longer hold the car in place
after approx. 2 seconds and the car will start to
roll backwards.<
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. This change is detected
and is reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period of
time.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration
>Snow chains are attached
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<

When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Special characteristics of winter tires
BMW recommends winter tires for winter roads
or at temperatures below +457/+76.
Although all-season M+S tires provide better
winter traction than summer tires, they gener-
ally fail to provide the same levels of cold-
weather performance as winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents.<
If the car is capable of speeds higher than that
permitted for the winter tires, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW center
can supply these labels.
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible. Always
protect tires against all contact with oil, grease
and fuels.
Do not exceed the maximum tire inflation pres-
sure indicated on the sidewall of the tire.
Swapping wheels between axles
BMW advises against swapping wheels
between the front and rear axles, even if all tires
have the same size, as this could impair driving
characteristics. If the tires are of mixed sizes,
swapping wheels between the axles is not per-
missible.
Snow chains*
Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your BMW center for
more information. Snow chains must be mounted in pairs and on the rear wheels only.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with chains.
Do not initialize the Flat Tire Monitor if
snow chains are mounted; otherwise, the
instrument might issue an incorrect reading.
When driving with snow chains, you may find it
helpful to activate DTC temporarily, refer to
page76.<
