BMW 2010 135i Coupe Manual De Propietario

chnology for

driving comfort

and

safe

When driving uphill on snow-covered roads,
in slush or on unplowed, snow-covered
roads

When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground

When driving with snow chains

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.

Hold the car in place by depressing the
brake.

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.
